The surface area of a cube is 96 square feet. Find the volume of the cube.

Answers

cube has six identical walls

96ft
² : 6 = 6 ft²  - one wall surface

pattern on the surface of the cube
A = a²
a - the edge of the cube

A = a
²    ⇔ a=√A
                  a = √(16ft)² = 4ft
V = volume
V = a³
V = (4ft)³ = 64 ft³

A line goes through{2,-3)and (-1, 0).slope =
Equation in point -slope form or equation in slope-intercept form

Answers

(2,-3)(-1,0)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (0 - (-3) / (-1 - 2) = 3/-3 = -1

y = mx + b
slope(m) = -1
use either of ur points (2,-3)...x = 2 and y = -3
now we sub and find b, the y int
-3 = -1(2) + b
-3 = -2 + b
-3 + 2 = b
- 1 = b

so ur equation is : y = - x - 1 (slope intercept form)

An internet service provider changes an initial fee of $65 and $18 per hour of labor for office internet installation. Which equation represents the total cost, C, of the installation after h hours of labor?

Answers

Answer:

The total cost (C) charged by the internet service provider = $65 + $18(n)

Step-by-step explanation:

Initial fee charged by the servic eprovider = $65

Cost per hour of labor for office internet installation = $18

The cost per hour be $18

Cost per two hours = 18 * 2 = $36

Cost per n number of hours = $18 (h)

where h represents the number of hours

The total cost (C) charged by the internet service provider = $65 + $18(n)

Find the area of the shaded region. Round your answer to the nearest hundredth.

Answers

4 semicircles of 90º=1 circle

Area of the shade region=area of the square -  area of a circle

1)we calculate the area of the square.
area of a square =slide²
slide=8 m

area of a square=(8 m)²=64 m².

2) we calculate the area of the circle:
area of a circle=πr²
r=4 m

area of a circle=π(4 m)²=16π m²≈50.27 m²

3) we calculate the area of the shaded region:

Area of the shaded region=64 m² - 50.27 m²=13.73 m²

answer:The area of the shaded regios is 13.73 m²
8 times 8 is 64 so rounded to the neArest hundreth it is 100
