Answer: question 5 is C

Question 4 is 37.68

Question 3 is 153.86 ft sq

The question about finding the area with a diameter of 16mm is 803.84

The next one is A. 25÷8

Step-by-step explanation:

C = 2 pi r

C = 2 pi (7.8) and you get 49.01

Becuse the question is asking to round c is the best choice

When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6

The formula for this one is A = pi r sq

You have the radius for this one is 7

Put 7 into that and you get. ~153.94

How do i simplify this equation?

Answer:

-6 = m (i'll show my work below)

Step-by-step explanation:

-6(m-7) + 7 = -8m + 37

-6m + 42 + 7 = -8m + 37

-6m + 49 = -8m +37

     -37     =      -37

-6m + 12  =  -8m

+6m       =    +6m

12 = -2m

/-2 = /-2

-6 = m

Where can I find the shaded area of this diagram?
erik [133]

To find the area of the figure, we divide it into two rectangles as follows:

And we find the area of each rectangle, which is given by:

\begin{gathered} A=b\cdot h \\ \text{where b = base and h = height} \end{gathered}

Area rectangle 1:

A=3\cdot10=30m^2

Area rectangle 2:

A=4\cdot6=24m^2

Therefore, the shaded area of the diagram is:

A=30+24=54m^2

Answer: 54 m^2

Answer:

  The function r(x)=(2+.25x)(240-20x) reveals that the revenue earned by the cafe from coffee sales will be $500 after 2 $0.25 price increases.

Step-by-step explanation:

The revenue from sales is the product of the price per cup and the number of cups sold.

For x increases of $0.25 each, the price per cup is (2 +0.25x).

For x increases of $0.25 each, the number of cups sold is (240 -20x).

Then the revenue as a function of x is ...

  r(x) = (2 +0.25x)(240 -20x)

The revenue function can be simplified to better show its zeros.

  r(x) = 5(8 +x)(12 -x)

The maximum is halfway between the zeros, so is at x = (-8 +12)/2 = 2.

When x=2, the revenue is ...

  r(2) = 5(8+2)(12-2) = 5(10)(10) = 500

__

The function <u>r(x)=(2+.25x)(240-20x)</u> reveals that the revenue earned by the cafe from coffee sales will be <u>$500</u> after <u>2</u> $0.25 price increases.
