Answer:

416 mi

Step-by-step explanation:

In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.

<em>Remember to find the area it is length x width</em>

  1. 9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottom
  2. Lastly for the last 2 squares to find the area you multiply 8 x 8 = 64
  3. In total, you will add 72+72+72+72+64+64 which equals 416

15. Apply Mathematics (1)(A) Suppose you have a box with a 4 X 4-in.
erastova [34]

Answer:

Step-by-step explanation:

Formula for calculating the surface area of the box S = 2(LW+LH+WH) where

L is the length of the box

W is the width of the box

H is the height of the box

If the box is square based with dimension 4 * 4in, then L = W = 4in. substituting this values given into the formula we will have;

S = 2(4(4)+4H + 4H)

S = 2(16+8H)

S = 32+16H

<em>Hence, The function that represents the surface area of this box as a </em>

<em>function of its height is S = 32+16H where H is the height of the box</em>

<em></em>

Given H = 6.5in, to evaluate the function, we will substitute h = 6.5in into the modeled equation;

S = 32+16H

S = 32+16(6.5)

S = 32+106

<em>S = 138in²</em>

<em>Hence the total surface area of the box is 138in²</em>

The estimated velocity v (in miles per hour) of a car at the end of a drag race is v=234\sqrt[3]{p/w} , where p is the horsepowe
Dennis_Churaev [7]

Answer:

299 miles per hour

Step-by-step explanation:

v=\frac{234}{\sqrt[3]{\frac{p}{w}}}

v=\frac{234}{\sqrt[3]{\frac{1311}{2744}}}

v\approx299

Therefore, the velocity of the car at the end of a drag race is 299 miles per hour

The cost y (in dollars) of renting a segway for x hours is y=30x+25. Find the initial fee and the cost per hour.
Hitman42 [59]

Given:

The cost y (in dollars) of renting a segway for x hours is

y=30x+25

To find:

The initial fee and the cost per hour.

Solution:

We have,

y=30x+25       ...(i)

The slope intercept form of a linear equation is

y=mx+b      ...(ii)

where, m is slope is b is y-intercept or initial value.

From (i) and (ii), we get

m=30,b=25

The value of m is 30, so the slope is 30. It means cost per hour is $30.

The value of b is 25, so y-intercept is 25. It means the initial fee is $25.
