The equation for volume of a sphere is:

Volume = 4/3 * PI * r^3

r is the radius = 1 inch

Volume is given as 4 cubic inches per second increase.

Given: dv/dt = 4 cubic inches per second.

Need to find dr/dt

Formula for volume of a sphere is: V = 4/3 * π * r^3

so now we have:

4 in^3 = 4 * π *1^2

Divide both sides by 4 * π *1^2

4 in^3 / 4π = 1/π inch per second.

The answer is 1/π inch per second ( exact answer)

or as a decimal: 0.3183 ( round as needed).

Hopi Corporation expects the following operating results for next year: Sales $ 400,000 Margin of safety $ 100,000 Contribution
Serggg [28]

Answer:

Hopi Corporation Total fixed expenses next year= $225,000

Step-by-step explanation:

Given,

Contribution margin ratio = 0.75

Current sales =  $400,000

Margin of Safety = $100,000

Breakeven sales can be calculated as,

Breakeven sales = Current Sales - Margin of safety

                            = $400,000 - $100,000

                            = $300,000

Fixed Expenses can be calculated as,

Fixed Expenses = Breakeven Sales × Contribution margin ratio

                           = $300,000 × 0.75

                           = $225,000

Answer: Expected total fixed expenses for Hopi next year is $225,000

Hey there!

The answer to your question is 313/495

To solve this, let's use the equation x = .6323232...

We want to get <u>ONLY THE REPEATING PART</u> on one side of the decimal, so we can multiply the equation by 101:

100x = 6.323232...

Now, we can take the original equation and subtract it from the new equation:

100x = 63.232...

     x =     .632...

 99x = 62.6

Now, divide both sides by 99.

x = 62.6/99

Simplify the fraction:

x = 313/495

Good luck! Hope it helps, and have a great day!

16. In the figure below, vertices D and F of ADEF lie on
Hatshy [7]

Answer:

J. 108°

Step-by-step explanation:

m<EDF = 180 - 148 = 32° (angles on a straight)

m<EFD = 180 - 140 = 40°(Angles in a straight line)

m<DEF = 180 - (m<EDF + m<EFD) (sum of triangle)

m<DEF = 180 - (32 + 40)

m<DEF = 180 - 72

m<DEF = 108°
