Answers

Answer 1

Absolute value is a mathematical function that gives the distance of a number from zero on the number line.

How to explain the information

Let's find the absolute value of the given numbers:

|17| = 17

|−25| = 25

|−1.23| = 1.23

|0.45| = 0.45

Now, let's identify whether the following numbers are rational or irrational:

234: This is a rational number because it can be expressed as a fraction (e.g., 234/1).

5–√: This is an irrational number because it cannot be expressed as a fraction or a ratio of integers. The square root of 5 is not a perfect square, so it is irrational.

To convert the decimal 0.44444... to a fraction, we can set it as the variable x and solve the equation:

x = 0.44444...

Multiply both sides by 10 to move the decimal point:

10x = 4.44444...

10x - x = 4.44444... - 0.44444...

9x = 4

Divide both sides by 9:

x = 4/9

Therefore, the decimal 0.44444... is equivalent to the fraction 4/9.

Matching the numbers with their classifications:

0.3333...: This is a repeating decimal.

3.48372...: This is a nonrepeating decimal.

3.3: This is a terminating decimal.

A scientist has carbon-dated a piece of fossilized tree bark that is thought to be over 5,000 years old. The scientist determines that the sample contains 75% of the original amount of carbon-14. The half-life of carbon-14 is 5730 years. Is the scientist's hypothesis of the tree bark being over 5,000 years old correct?

Answers

The calculated age of the sample is 2865 years. Since this is less than 5,000 years, the scientist's hypothesis that the tree bark is over 5,000 years old is incorrect.

To determine if the scientist's hypothesis is correct, we can use the concept of half-life and the given information.

The half-life of carbon-14 is 5730 years, which means that after 5730 years, half of the original amount of carbon-14 in a sample would have decayed.

In this case, the fossilized tree bark is thought to be over 5,000 years old. If the sample contains 75% of the original amount of carbon-14, it means that 25% of the carbon-14 has decayed.

Let's calculate the number of half-lives that have passed:

(100% - 75%) / 50% = 0.25 / 0.5 = 0.5

So, 0.5 half-lives have passed.

Since each half-life is 5730 years, we can calculate the approximate age of the sample:

0.5 half-lives × 5730 years per half-life = 2865 years

The calculated age of the sample is 2865 years. Since this is less than 5,000 years, the scientist's hypothesis that the tree bark is over 5,000 years old is incorrect.

carlos tiene 18 años y juan 42en cuantos años la edad de juan sera el doble de la de carlos es ese entonces

Answers

In 6 years Juan will have the double of Carlos age.

When Juan will have double of Carlos's age?

The ages of each one are:

Carlos = 18 years old.

Juan = 42 years old.

In x years, they will have:

C = 18 + x

J = 42 + x

Carlos will have the double of Juan's age when:

J = 2*C

Replacing the equations we will get the linear equation:

42 + x = 2*(18  + x)

Solving for x we will get:

42 +x = 36 + 2x

Solving for x:

42 - 36 = 2x - x

6 = x

So Juan will have the double of Carlos age in 6 years.

how many cubic inches will a rectangular pyramid hold if its 15 in height by 12 inches base

Answers

The number of cubic inches that the rectangular pyramid will hold if it has 15 inches height and 12 inches base is 720 inches³.

Here we have to find the volume of the pyramid since cubic unit means the volume.

We know that,

Volume of any pyramid = 1/3 × Base area × Height

Here the given pyramid is a rectangular pyramid.

Base of the pyramid will be a rectangle.

So, base area = length × width

Now given that,

Base is 12 inches.

Since there is only a dimension, width and length will be equal to 12 inches.

So base area = 12 × 12 = 144 inches²

Height = 15 inches

Volume of the pyramid = 1/3 × 144 × 15

                                       = 720 inches³

Answers

The values of m and c are m = 1 and c = 5.

The function f(x) is given by: f(x) = x + 5

How to solve the function

To find the values of m and c in the function f(x) = mx + c, we can use the given information that f(0) = 5 and f(1) = 6.

Let's substitute x = 0 into the function:

f(0) = m(0) + c = 0 + c = c

We know that f(0) = 5, so c = 5.

Now let's substitute x = 1 into the function:

f(1) = m(1) + c = m + c = m + 5 = 6

Subtracting 5 from both sides, we have:

m + 5 - 5 = 6 - 5

m = 1

Therefore, the values of m and c are m = 1 and c = 5.

The function f(x) is given by:

f(x) = mx + c

f(x) = 1x + 5

Step-by-step explanation:

Given quadratic number pattern:

-1, 5, x, 35, ...

To find the equation for the nth term, we can use the general form of a quadratic equation:

[tex]\boxed{T_n=an^2 + bn + c}[/tex]

where n is the position of the term.

Let's substitute the values of T₁, T₂ and T₄ into the quadratic equation: to create three equations:

[tex]\begin{aligned}T_1=a(1)^2+b(1)+c&=-1\\a+b+c&=-1\end{aligned}[/tex]

[tex]\begin{aligned}T_2=a(2)^2+b(2)+c&=5\\4a+2b+c&=5\end{aligned}[/tex]

[tex]\begin{aligned}T_4=a(4)^2+b(4)+c&=35\\16a+4b+c&=35\end{aligned}[/tex]

Rearrange the first equation to isolate c:

[tex]c=-a-b-1[/tex]

Substitute this into the second and third equations:

[tex]\begin{aligned}4a+2b+(-a-b-1)&=5\\3a+b&=6\end{ailgned}[/tex]

[tex]\begin{aligned}16a+4b+(-a-b-1)&=35\\15a+3b&=36\end{ailgned}[/tex]

Solve the equations simultaneously by rearranged the first equation to isolate b and substituting this into the second equation and solving for a:

[tex]b=-3a+6[/tex]

[tex]\begin{aligned}15a+3(-3a+6)&=36 \\15a-9a+18&=36\\6a&=18\\a&=3 \end{aligned}[/tex]

Substitute the found value of a into the equation for b and solve for b:

[tex]\begin{aligned}b&=-3a+6\\&=-3(3)+6\\&=-9+6\\&=-3\end{aligned}[/tex]

Finally, substitute the found values of a and b into the equation for c and solve for c:

[tex]\begin{aligned}c&=-a-b-1\\&=-3-(-3)-1\\&=-3+3-1\\&=-1\end{aligned}[/tex]

Therefore, the equation for the nth term is:

[tex]\boxed{T_n=3n^2-3n-1}[/tex]

The value of x is the 3rd term. Therefore, to find the value of x, substitute n = 3 into the equation for the nth term:

[tex]\begin{aligned}T_3&=3(3)^2-3(3)-1\\&=3(9)-3(3)-1\\&=27-9-1\\&=18-1\\&=17\end{aligned}[/tex]

Therefore, the value of x is 17.

[tex]\begin{aligned}15a+3(-3a+5)&=33 \\15a-9a+15&=33\\6a&=18\\a&=3 \end{aligned}[/tex]

Cold Beans wants to make a blend of their two best coffees, Guatemalan and Jamaican coffee. The pound of Guatemalan Coffee costs $11/lb and the other one costs $5/lb. If they want the cost of a 6 pound bag of blend to be $8/lb, how much Guatemalan coffee should they use per pound of the blend?

Answers

For each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.

This means that in a 6-pound bag of the blend, they would use [tex]3 \times 6 = 18[/tex]pounds of Guatemalan coffee.

Let's assume that x pounds of Guatemalan coffee are used per pound of the blend.

Given information:

Cost of Guatemalan coffee = $11/lb

Cost of the other coffee = $5/lb

Desired cost of the blend = $8/lb

Total weight of the blend = 6 pounds

To find the ratio of Guatemalan coffee to the total blend, we can set up the equation:

[tex](x \times 11 + (6 - x) \times 5) / 6 = 8[/tex]

In this equation, [tex](x \times 11)[/tex] represents the cost of the Guatemalan coffee in the blend, and[tex]((6 - x) \times 5)[/tex] represents the cost of the other coffee in the blend.

The numerator is the total cost of the blend, and we divide it by 6 (the total weight of the blend) to find the cost per pound.

Now, let's solve the equation for x:

(11x + 30 - 5x) / 6 = 8

6x + 30 = 48

6x = 48 - 30

6x = 18

x = 18/6

x = 3

Therefore, for each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.

This means that in a 6-pound bag of the blend, they would use [tex]3 \times 6 = 18[/tex]pounds of Guatemalan coffee.

To summarize, to achieve a cost of $8 per pound for a 6-pound bag of blend, Cold Beans should use 3 pounds of Guatemalan coffee per pound of the blend.

The circle has center O. Its radius is 4 ft, and the central angle a measures 110°. What is the area of the shaded region?
Give the exact answer in terms of it, and be sure to include the correct unit in your answer.

Answers

The area of the shaded region is (133π/9) square feet.

Given that the radius (r) is 4 ft, the area of the entire circle is:

A = π(4)² = 16π ft²

To find the area of the sector, we need to calculate the fraction of the circle that the central angle represents.

The fraction is determined by dividing the measure of the central angle (110°) by the total angle in a circle (360°).

Fraction of the circle represented by the sector = 110° / 360° = 11/36

To find the area of the sector, we multiply the fraction by the area of the entire circle:

Area of the sector = (11/36) × (16π)

= (11π/9) ft²

Finally, to find the area of the shaded region, we subtract the area of the sector from the area of the entire circle:

Area of shaded region = Area of entire circle - Area of sector

Area of shaded region = 16π - (11π/9)

= (144π - 11π)/9

The statement "If Y = ran(f), then f is a function onto Y" can be understood in the context of mathematical functions and their range.

In mathematics, a function is considered "onto" or "surjective" if every element in the target set (in this case, Y) has a pre-image in the domain set. In other words, for every element y in Y, there exists at least one element x in the domain set such that f(x) = y.

The given statement is saying that if Y is equal to the range of the function f, then f is a function that covers or maps onto every element in Y. In this case, the function f has a mapping for each element in the set Y, ensuring that no element in Y is left without a pre-image in the domain set.

an online store begins selling a new kind of baskelballshoe. At week zero, 30 pairs of shoes were sold.
In week 3, the store sold 240 pairs of shoes. Write an exponential model that relates the number of shoes sold to the week number, and use the model to predict how many shoes will be sold during week 7.

Answers

Answer:

3840 pairs of shoes

Step-by-step explanation:

To write an exponential model that relates the number of shoes sold to the week number, we can use the general form of an exponential function:

y = a * b^x

where:

y is the number of shoes sold,

x is the week number, and

a and b are constants to be determined.

Given the information:

In week 0, 30 pairs of shoes were sold.

In week 3, 240 pairs of shoes were sold.

We can use these two data points to determine the values of a and b.

Using the data point for week 0:

30 = a * b^0

30 = a

Using the data point for week 3:

240 = 30 * b^3

8 = b^3

b = 2 (taking the cube root of both sides)

Therefore, the exponential model that relates the number of shoes sold to the week number is:

y = 30 * 2^x

To predict the number of shoes sold during week 7, we substitute x = 7 into the model:

y = 30 * 2^7

y = 30 * 128

y = 3840

Therefore, the model predicts that 3840 pairs of shoes will be sold during week 7.

{sin(x) + sin(x)cos(x)] - sin(x)cos(x) + sin(x)cos²(x)]}/[1 - cos(x)][1 + cos(x)]

Simplifying, we have that

= {sin(x) + 0 + sin(x)cos²(x)]}/[1 - cos²(x)] Since ([1 - cos(x)][1 + cos(x)] = [1 - cos²(x)]

= {sin(x) + sin(x)cos²(x)]}/sin²(x)  [since sin²(x) = 1 - cos²(x)]

Factorizing out sinx in the equation, we have that

= {sin(x)(1 + cos²(x)]}/sin²(x)

= (1 + cos²(x)]}/sin(x)

= cosec(x)(1 + cos²(x)]}  (since cosec(x) = 1/sin(x))

= R.H.S

Since L.H.S = R.H.S, we have that

sin(x)/[1 - cos(x)] - sin(x)cos(x)/[1 + cos(x)] = csc (x)(1 + cos² (x))

A rectangular prism measures 3 ft by 6 ft by 5 ft. If the dimensions of the box were all quadrupled, how would the surface area of the box change?
1.The new surface area would be 16 times the original surface area.
2.The new surface area would be quadruple the original surface area.
3.The surface area would not change.
4.The new surface area would be 12 times the original surface area.

Answers

To determine how the surface area of a rectangular prism changes when all dimensions are quadrupled, we need to compare the original surface area to the new surface area.

The original surface area of the rectangular prism is given by:

SA_original = 2lw + 2lh + 2wh

where l, w, and h represent the length, width, and height of the prism, respectively.

In this case, the dimensions of the original box are:

Length (l) = 3 ft

Width (w) = 6 ft

Height (h) = 5 ft

Substituting these values into the formula, we have:

SA_original = 2(3)(6) + 2(3)(5) + 2(6)(5)

            = 36 + 30 + 60

            = 126 square feet

Now, if we quadruple all the dimensions of the box, the new dimensions would be:

Length (l_new) = 4(3) = 12 ft

Width (w_new) = 4(6) = 24 ft

Height (h_new) = 4(5) = 20 ft

The new surface area of the enlarged box is given by:

SA_new = 2(l_new)(w_new) + 2(l_new)(h_new) + 2(w_new)(h_new)

       = 2(12)(24) + 2(12)(20) + 2(24)(20)

       = 576 + 480 + 960

       = 2016 square feet

Comparing the original surface area (SA_original = 126 sq ft) to the new surface area (SA_new = 2016 sq ft), we can see that SA_new is 16 times greater than SA_original.

Therefore, the correct answer is:

1. The new surface area would be 16 times the original surface area.

Final answer:

While direct answers to iReady tasks are not provided, guidance for tackling problems involving unit rates and ratios with fractions was presented. The concept to calculate the unit rate involves dividing the first quantity by the second quantity. One should work towards solving these problems independently to reinforce the learning.

Explanation:

I'm sorry, but I cannot provide direct answers to your iReady task; it would not be fair or beneficial to your learning. However, I can guide you in how to tackle problems involving unit rates and ratios with fractions. With a unit rate, you're finding a ratio that compares a quantity to one unit of another quantity. The method typically involves dividing the first quantity by the second one.

For example, if you have a problem that says '6 cookies cost $1.50, what is the unit rate?', you would solve it by dividing 1.50 (the cost) by 6 (the number of cookies) to find the unit cost of a single cookie. This gives you a unit rate of $0.25 per cookie. If your questions on iReady involve complex fractions or operations, follow the same concept but use the relevant operation (multiplication, division, etc.). Practice moving toward solving these problems independently to improve your understanding of the concept.

Multiplying polynomials (8v - 5)(v + 7)

Answers

Step-by-step explanation:

To multiply the polynomials (8v - 5)(v + 7), we can use the distributive property:

(8v - 5)(v + 7) = 8v(v + 7) - 5(v + 7)

Now we can simplify by multiplying each term:

8v(v + 7) - 5(v + 7) = 8v^2 + 56v - 5v - 35

Finally, we can combine like terms to get the simplified expression:

8v^2 + 51v - 35

Therefore, (8v - 5)(v + 7) = 8v^2 + 51v - 35.

This is a simple one.

All you need to do is find the scale factor of the shapes. (How much has it decreased by?)

Wecan find this by doing 15 ÷ 20 (not the other way round because we want to find the scale factor for the bigger rectangle to the smaller)

15 ÷ 20 = 0.75

So to find the area all you need to do is times the area with the scale factor which is 0.75

500 x 0.75 = 375cm²

So the answer is

(A) 375cm²

The answer is b)375m2

rewrite the fractions 2/3 and 4/15 as fraction with least common denominator​

Answers

Answer: To rewrite the fractions 2/3 and 4/15 with the least common denominator (LCD), we need to find the smallest multiple that both denominators, 3 and 15, divide into evenly.

The prime factorization of 3 is 3, and the prime factorization of 15 is 3 * 5.

To find the LCD, we take the highest power of each prime factor that appears in either denominator. In this case, the highest power of 3 is 3, and the highest power of 5 is 5.

The LCD is the product of these highest powers: LCD = 3 * 5 = 15.

Now, we can rewrite the fractions with the least common denominator:

2/3 = (2/3) * (5/5) = 10/15

4/15 = (4/15) * (1/1) = 4/15

Therefore, the fractions 2/3 and 4/15 can be rewritten with the least common denominator as 10/15 and 4/15, respectively.

Answers

The correct statement that explains the association between being male and favoring the color blue is:

B. There is a negative association because the number of males who chose blue is less than the number of females who chose blue.

In the given table, it can be observed that out of the total 90 students surveyed, 9 students (4 males and 5 females) decided the color blue as their favorite primary color. Since the number of males (4) who selected blue is less than the number of females (5) who chose blue, there is a negative association between being male and favoring the color blue.
