Answer:

41

Step-by-step explanation:

113 = x + 72

subtract 72 from both sides

41 = x  

Answer:

22 11/16 or 22.68

Step-by-step explanation:

Turn the mixed numbers to fractions

[tex]\frac{11}{2} *\frac{33}{8}[/tex]

Then multiply both Numerators

11 x 33=363

Also do the same to the Denominators

2 x 8=16

You get  [tex]\frac{363}{16}[/tex]

Simplify and it becomes 22 11/16 or 22.68

Answer:

8 4/25

Step-by-step explanation:

2 2/5 = 12/5

3 2/5 = 17/5

12×17/5×5

204/25 = 8 4/25

Answer:

[tex] 8 \dfrac{4}{25} [/tex]

Step-by-step explanation:

[tex] 2 \dfrac{2}{5} \times 3 \dfrac{2}{5} = [/tex]

[tex] = \dfrac{12}{5} \times \dfrac{17}{5} [/tex]

[tex] = \dfrac{204}{25} [/tex]

[tex] = 8 \dfrac{4}{25} [/tex]

Answer:

{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}

Step-by-step explanation:

you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)

an example of a function would be {(1,2) (3,4) (5,6)}

an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.

using this, another example of a function would be {(1,2) (3,2) (5,2)}

an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

i cant process what your saying

Answer:

1)  a = 16.38 (nearest hundredth)

   b = 11.47 (nearest hundredth)

2)  b = 14.14 (nearest hundredth)

    c = 15.36 (nearest hundredth)

Step-by-step explanation:

Sine Rule

[tex]\sf \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

Question 1

The interior angles of a triangle sum to 180°

⇒ m∠B = 180° - 90° - 55° = 35°

Given:

[tex]\implies \sf \dfrac{a}{\sin 55}=\dfrac{b}{\sin 35}=\dfrac{20}{\sin 90}[/tex]

[tex]\implies \sf a=\dfrac{20\sin 55}{\sin 90}=16.38304089...[/tex]

[tex]\implies \sf b=\dfrac{20\sin 35}{\sin 90}=11.47152873...[/tex]

Question 2

The interior angles of a triangle sum to 180°

⇒ m∠B = 180° - 90° - 23° = 67°

Given:

[tex]\implies \sf \dfrac{6}{\sin 23}=\dfrac{b}{\sin 67}=\dfrac{c}{\sin 90}[/tex]

[tex]\implies \sf b=\dfrac{6\sin 67}{\sin 23}=14.13511419...[/tex]

[tex]\implies \sf c=\dfrac{6\sin 90}{\sin 23}=15.35582799...[/tex]

Answer:

There is a positive correlation happening.

Step-by-step explanation:

A positive correlation happens when both of the sequences are going up. In the first sequence, the terms go up by 2. In the second one, the terms go up by 1. While the do not have the same common difference, the two sequences still increase. This makes the relationship a positive one.

Answer:

2,4,6,8,10 You multiply by 2 each time

1,2,3,4,5 You add 1 each time

Step-by-step explanation:

You multiply 2 and you add 1

Answer:

No

Step-by-step explanation:

It is not an appropriate method because if you add all of the people that got 1, 3, and 5 together to get all the people that got the 20% discount, you get 140/400 people, and in order for it to be half there would have to be, or close enough to, a total of 200/400 people.

15% discount = 185/400 or 46.25%

20% discount = 140/400 or 35%

30% discount = 75/400 or 18.75%

answer:

A dot plot. The numbers 10 through 50, in increments of 5, are indicated. There are diamonds indicated at 12, 20, 33, 40, and 49. The data are as follows: 12, 1 dot; 14, 1 dot; 16, 1 dot; 18, 1 dot; 20, 1 dot; 24, 1 dot; 26, 1 dot; 28, 1 dot; 31, 1 dot; 33, 2 dots; 36, 1 dot; 38, 1 dot; 39, 1 dot; 40, 1 dot; 44, 1 dot; 46, 1 dot; 48, 1 dot; 49, 1 dot.

Answer:

The answer is 192.33

Step-by-step explanation:

A coaster measures 7 cm in diameter. The total area of five roller coasters must be determined.

The diameter of the coaster is d = 7 cm

The radius is:

[tex]r =[/tex] [tex]\frac{d}{2}[/tex]

[tex]=[/tex] [tex]\frac{7}{2}[/tex] [tex]cm[/tex]

[tex]= 3.5[/tex] [tex]cm[/tex]

The area of the circle is:

[tex]A =[/tex] [tex]\pi r^{2}[/tex]

= (3.14 x 3.5^2) [tex]cm^{2}[/tex]

[tex]= 38.465[/tex] [tex]cm^{2}[/tex]

We now know that the area required for five coasters is 5 x 38.465 [tex]cm^{2}[/tex]

[tex]= 192.325[/tex] [tex]cm^{2}[/tex]

Round 192.325 to the nearest hundredth and you'll get 192.33 as the correct answer.

Answer:

25

Step-by-step explanation:

(You can do this differently, but I chose to do it like this)

First, convert the 1816 kilograms to pounds.

1816 kilograms = 4003.595 pounds

Then, we can divide 4003.595 pounds by 160 to figure out how many 160-pound people the balcony can hold.

4003.595 ÷ 160 ≈ 25.02

If the balcony holds 26 people, it will collapse, so the answer must be 25.

Answer:

942.4777960769 square feet - sorry if I am wrong

Step-by-step explanation:

The area fo a circle is pi x Radius to the power of 2. 20 ft is the radius and 20x20= 400. 400 x Pi = 1,256.6370614359. The house takes up 1/4 of the whole area so 1,256... ÷ 4 = 314.159265359. This is the value of 1/4 of the area so times 314... times 3 to get 3/4ths of the area. 942.4777960769

Answer:

125˚

Step-by-step explanation:

The angles given are supplementary. So we can set up the equation :

(3x+5)+(x+15)=180

Then we can solve for x.

Combine like terms:

4x+20=180

4x+20-20=180-20

4x=160

4x/4=160/4

x=40

Now we plug in 40 for x.

3(40)+5=<A

120+5=<A

<A=125

Answer:

Step-by-step explanation:

It is necessary to isolate the term of x from one side of an inequality to find its solution.

First, add by 8 from both sides.

[tex]\sf{-4x-8+8 > -20+8}[/tex]

Solve.

-20+8=-12

Rewrite the problem down.

[tex]\sf{-4x > -12}[/tex]

Multiply by -1 from both sides.

(-4x)(-1)<(-12)(-1)

Solve.

Multiply the numbers from left to right.

(-12)(-1)=12

4x<12

Divide by 4 from both sides.

4x/4<12/4

Solve.

Divide the numbers from left to right.

12/4=3

x<3

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

Option D.

These equations prove it true.

[tex]-4 * 2 - 8 = -16 > -20[/tex]

[tex]-4 * 1 - 8 = -12 > -20[/tex]

The only reason these two equations are correct, is because on the number line it shows: Any negative number further to the right than the last negative number is greater than that number.

Answer:The difference between the medians is 2.5

Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5

Step-by-step explanation:

To find the quadrent a coordinate pair is in:

1. look at the "x" value in the (x,y) pair

2. if its negetive go leftward and if its positive go rightward

3. once you have moved to the respective x location do the same thing with the y coordinate in the (x,y) pair

4. up is positive for y and down is negitive.

for example (3,3) would be 3 to the right and 3 up so its in the top right quadrent

(-3,-3) would be 3 left and 3 down so its in the bottom left  

Answer:

Step-by-step explanation:

Answer:

Reflected along x axis

Translated 7 units to the right

A transformation of a point is the movement of the point from its initial position to a new position. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.

Figure ABCD has A at (- 4, 4), B at (- 2, 2), C at (- 2, - 1), D at (- 4, 1).

If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)

If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:

It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)

It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

Answer:

First, we must know that;

Given this, multiply the pounds you are given by 2.2 kilograms since 2.2 kilograms make up one pound.

23.4(2.2)

= 51.48 kilograms

23.4 = pounds

2.2 = kilograms (that make up one single pound)
