Answer:

7.) 53.38

8.) 18.84

9.) 87.92

Step-by-step explanation:

7.)

For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.

The formula for finding the circumference is 2 × π × 8.5

2 × 3.14(π) = 6.28.

6.28 × 8.5 = 53.38

8.)

For the second question, we can see that the radius is now given to us which is 3ft.

The formula for finding the circumference is 2 × π × 3

2 × 3.14(π) = 6.28.

6.28 × 3 = 18.84

9.)

For the third question the raduis is also given to us, which is 14 in.

The formula for finding the circumference is 2 × π × 14.

2 × 3.14(π) = 6.28.

6.28 × 14 = 87.92

Answer:

The following is an income statement using the Contribution format.

...........................Income Statement for Rivieremia Corp................................

Sales ........................................................................$1,500,000

Less Variable Costs................................................<u>($1,200,000)</u>

Contribution Margin..............................................$300,000

Less Fixed Costs....................................................<u>($200,000)</u>

Operating Income .................................................$100,000

Less Tax...................................................................<u>.($10,000)</u>

Net Income...............................................................$90,000

Tax = 10% * 100,000 = $10,000

Proving breakeven is $1,000,000.

The breakeven point for a company can be calculated by dividing the Fixed cost by the contribution margin ratio.

Contribution margin ratio = Contribution margin / Sales

= 300,000/1,500,000

= 20%

= Fixed Cost/ Contribution Margin ratio

= 200,000/20%

= $1,000,000

Degree of Operating Leverage = Contribution Margin/ Operating Income

= 300,000/100,000

= 3

Does anyone know how to solve this?
masya89 [10]

Answer:

b = -125/9

Step-by-step explanation:

1 + log5 ( -9b) = 4

Subtract 1 from each side

1 -1+ log5 ( -9b) = 4-1

log5 ( -9b) = 3

Raise each side to the base 5

5^  log5 ( -9b) = 5^3

This will cancel the log5

-9b = 125

Divide each side by 9

-9b/-9 = 125/-9

b = -125/9
