Answer:

The answer is 78%

Step-by-step explanation:

Step 1: The given regression equation y = -0.414x + 106.55

Step 2: The length of the film  = 70 minutes

Step 3: Plug in x = 70 in the given equation and find the value of y.

y = -0.414 (70) + 106.55

y = -28.98 + 106.55

y = 77.57

Y = 78%

Hope you will understand. :)

Determine the value of pie for a circle with a diameter of 9 inches and a circumference of 28.26 inches
jarptica [38.1K]

Hello from MrBillDoesMath!

Answer:

3.14

Discussion:

C = circumference, r = radius, d = diameter = 2 r

For a circle, C = 2 Pi r  = d Pi

Substituting the values in the question gives


C = d Pi

28.26 = 9 Pi       => divide both sides by 9

Pi = 28.26/9  = 3.14


Thank you,

Find the volume of the square pyramid below.
miv72 [106K]

Hello!

\bf ANSWER

The volume of the square pyramid is approximately \boxed{ \bf 19.19~km^3}

____________________________________________________________

\bf EXPLANATION

V = a^{2}\frac{h}{3}

First, we must find the area of the square base.

A = l * w

A = 3.5 * 3.5

A = 12.25 km^2

The area of the base is 12.25 km^2. Now, multiply the base area by the perpendicular height. Then divide by 3.

V = (12.25 * 4.7) / 3

V = 19.1916666667

V ≈ 19.19 km^3

Please answer hurry!!!!

The best way to solve this problem is by plugging in each answer choice for both equations and seeing which one works. You can already see that choice A doesn't work because -1 is not greater than or equal to 4. That means you just need to test choices B and C!

Choice B (4, -2)
x + y  \geq 6\\&#10;4 + -2  \geq 6\\&#10;2  \geq  6 &#10;
2 is not greater than or equal to 6, so choice B doesn't work.

Choice C (4, 2)
x + y \geq 6\\ &#10;4 + 2 \geq 6\\ &#10;6 \geq 6 \\\\&#10;x  \geq 4\\&#10;4 \geq 4
Since 6 is equal to 6 and 4 is equal to 4, choice C works!
