Which linear line equation has no solution?

Step-by-step explanation:

pizza = circle

the area of a circle is

pi×r²

r = radius (half of diameter), in our case 15/2 = 7.5 in.

the total area of the whole pizza (circle) is

pi×7.5² = 56.25×pi = 176.7145868... in²

it is cut into 12 slices. Carson eats 5 of these 12 slices.

that means he eats 5/12 of the whole area :

176.7145868... × 5/12 = 73.63107782... in²

Answer:

50°

Step-by-step explanation:

the sum of the angles of a quadrilateral is 360°

so

2x + 110 + x + 10 + 90 = 360

2x + x = 360 - 110 - 10 - 90

3x = 150

x = 150 : 3

x = 50°

-------------------------

check

50 + 10 + 2 * 50 + 110 + 90 =

360°.

the answer is good

Answer:

x = 50

2x = 110°

(x + 10)° = 60°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral is 360°

⇒ 2x° + (x + 10)° + 110° + 90° = 360°

⇒ 2x° + x° = 360° - 110° - 90° - 10°

⇒ 3x° = 150°

⇒ x = 50

Substitute found value of x into the expressions and solve:

⇒ 2x° = 2(50)° = 110°

⇒ (x + 10)° = (50 + 10)° = 60°

Answer:

a.) Graph is attached; blue is Petunia's and red is Billy's

b.) Number of Hours: 4 | Cost: 32 Pounds

Answer:

Step-by-step explanation:

In a parallelogram, opposite angles are congruent.

∠A = ∠C

4x + 20 = x + 26

Step 1: To find the valu of 'x', first subtract 20 from both sides

4x = x + 26- 20

4x = x + 6

Step2: Now, subtract 'x' from both sides

4x -x = 6

3x = 6

Step:3: divide both sides by 3

x = 6/3

x = 2

∠A = 4*2 + 20

      = 8 + 20

∠A = 28°

Answer:

The z-test statistic for a hypothesis test in which the null hypothesis states that the population proportion, p, equals 0.14 if the following sample information is present (n = 200; x = 31) is z = .6114.

Step-by-step explanation:

The z-test statistic formula is:

We are given x = 31 and n = 200, so we can solve for [tex]\hat{p}[/tex] : 31/200 = .155.

The population proportion, [tex]p=.14[/tex], is given in the problem.

We can substitute the known values into the z test statistic formula:

The z-test statistic for this problem is z = .6114.

y + 2 = -3/8x + 3

y = -3/8x + 1

Answer:

  no solution

Step-by-step explanation:

A graphing calculator shows the left-side expression is never equal to the right-side expression for any real-number value of A.

The equation is not an identity, and has no solution.

Additional comment

By subtracting the right-side expression from the left-side expression, we get an equation of the form f(A)=0. Any solutions will be x-intercepts of the graph. The graph for this equation never comes close to crossing the x-axis.

The function represents a decay of 88.97% per unit increase in x.

What is percentage?

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

The exponential function can be written in the form of y = [tex]ab^{x}[/tex], where:

a is the initial value or the value of the function when x = 0

b is the base or the factor by which the function changes for each unit increase in x

Comparing this form to the given function, we can see that:

a = 8600

b = 0.11

To determine whether the function represents growth or decay, we need to consider the value of the base (b). If the base is greater than 1, then the function represents growth, and if the base is between 0 and 1, then the function represents decay.

In this case, the base (0.11) is between 0 and 1, so the function represents decay.

To determine the percentage rate of decrease, we can use the formula:

Percentage change = (new value - old value) / old value * 100%

Since the function represents decay, the old value is the initial value (a = 8600) and the new value is the value of the function when x = 1:

y(1) = 8600(0.11)¹ = 946

Plugging in these values, we get:

Percentage change = (946 - 8600) / 8600 * 100% = -88.97%

Therefore, the function represents a decay of 88.97% per unit increase in x.

Using the Central Limit Theorem, it is found that the sampling distribution of the sample proportion of the 50 questions on which you get the correct is approximately normal, with mean of 0.7 and standard error of 0.0648.

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

In this problem, we have that p = 0.7, n = 50, hence the mean and the standard deviation are given as follows:

[tex]\mu = p = 0.7[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.7(0.3)}{50}} = 0.0648[/tex]

1111/1250

Step-by-step explanation:

Hey there!

To find what fraction represents the decimal shown, you can take each answer choice, and divide the two numbers

We can do this because a fraction is a simple way of dividing two rational numbers

Our answer is 1111/1250

In order to check if this is correct, we can just divide 1111 and 1250

When you divide this, you get 0.8888...

So the fraction that represents 0.888... is 1111/1250

A fraction that represents the decimal 0.8888 is: 1111/1250

In Mathematics, fractions are represented as a numerical value, can be defined as the parts of a whole. A fraction can be a portion or section of any quantity out of a whole, where, the whole can be any number, a specific value, or a thing.

Given is decimal number 0.8888... we need to convert it into a fraction,

Since the number has 4 decimal places, then the first thing to do is multiply and divide the number by 10000.

We have then:

0.8888* (10000/10000) = 8888/10000

Simplifying we have:

8888/10000 = 4444/5000

4444/5000 = 2222/2500

2222/2500 = 1111/1250

Hence, the fraction that represents the decimal 0.8888 is: 1111/1250

Distance is the product of speed and time. The rate at which the distance between the ships changes at 4:00 p.m is 27.293 km/h.

Distance is the product of speed and time. It is given by the function,

[tex]\rm Distance = Time \times speed[/tex]

Given at noon the distance between two ships is 170 km. Furter ship A is moving towards the east at a speed of 40 km/h, therefore, the distance covered by Ship A in 4 hours will be,

[tex]\rm \text{Distance covered by Ship A in 4 hours} = 4 \times 40 = 160\ km[/tex]

The distance covered by Ship B in 4 hours will be,

[tex]\rm \text{Distance covered by Ship B in 4 hours} = 4 \times 15= 60\ km[/tex]

At 4 pm the distance between the two ships is the hypotenuse of the red triangle as shown below,

[tex]\rm Hypotenuse = \sqrt{10^2 + 60^2} = \sqrt{100+3600 }= 60.827\ km[/tex]

The rate of change in the distance between the two ships can be written as,

[tex]\rm \text{Rate of change of distance} = \dfrac{170-60.827}{4} = 27.293\ km/h[/tex]

Hence, the rate at which the distance between the ships changes at 4:00 p.m is 27.293 km/h.
