Answer:

Step-by-step explanation:

In most cases the first step is to create an equation to solve for the missing variable

But in this case we are already given the equation

(7.25h + 5 = 6.5h + 10.25)

All we have to do is solve for h

7.25h + 5 = 6.5h + 10.25

Step 1 subtract 5 from both sides

7.25h = 6.5h + 5.25

Step 2 subtract 6.5h from both sides

0.75h = 5.25

Step 3 divide both sides by .75

h = 7

So at 7 hours the cost will be the same for both instructors

Hello there! :)

4x=22-2

4x=20

Divide both sides by 4 to isolate x:

x=5

Remember to divide both sides.

Hope this helps!

The 8 foot diameter circular table has a 4 foot wide extension. What is the total area with the extension? How does the area com

galina1969 [7]

Answer: the total area with the extension S≈82,3 foot², S>S'.

Step-by-step explanation:

D₁=8 foot D₂=10 foot a wide extension = 4 foot.

1) Let the total area with the extension S is the area of the circular table S₁

plus a wide extension S₂.

Considere S₁:

$R_1=\frac{D_1}{2} \\R_1=\frac{8}{2} \\R_1=4 foot.\\S_1=\pi* R_1^2\\S_1=\pi *4^2\\S_1=16*\pi \\S_1\approx50,3\ foot^2.\\$

$S_2=8*4\\S_2=32 \ foot^2.$

$S\approx50,3+32\\S\approx82,3 \ foot^2.$

2)\ Considere S':

$R_2=\frac{D_2}{2} \\R_2=\frac{10}{2} \\R_2=5 \ foot.\\S'=\pi *R^2\\S'=\pi *5^2\\S'=25*\pi \\S'\approx78,5\ foot^2.$

S>S'.

Good luck an' have a nice day!
