Please help me ASAP yall!!!

Mathematics
1 answer:
ASHA 777 [7]3 years ago
8 0

Answer:

60

Step-by-step explanation:

<C+<D = 180 since they form a straight line

5x+20 +3x = 180

8x+20 = 180

Subtract 20 from each side

8x+20-20 = 180-20

8x = 160

Divide by 8

8x/8 = 160/8

x = 20

We want to find angle D

<D = 3x= 3*20 = 60

The function f(x)=600+2x over x yields the average cost in dollars for a company to produce x calendars. Which statement best fi
nevsk [136]

Answer:

The correct option is a.

Step-by-step explanation:

The average cost function is

f(x)=\frac{600+2x}{x}

Where x is the number of calendars produced.

The average cost formula is

AC=\frac{\text{Total Cost}}{\text{Number of items}}

Therefore the total cost is defined b the function

g(x)=600+2x

Here 600 is the initial cost and the cost each unit is 2.

Initial cost is the fixed cost which occurs at zero level of productivity.

The company spends $600 on a new computer and printer before beginning the project. The option (a) is correct.

8th grade teachers and students from M.I.T went on a field trip to an zoo. Tickets
alukav5142 [94]

As there are multiple answers going with trial and error seems good in this case.

A

5.00 + 5.00 + 5.00 + 5.00 = 20.00

3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 31.5

20.00 + 31.5 = 51.5

B

5.00 + 5.00 + 5.00 + 5.00 = 20.00

3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 35.00

20.00 + 35.00 = 55.00

C

5.00 + 5.00 + 5.00 = 15.00

3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 + 3.50 = 31.5

15.00 + 31.5 =46.5

Knowing that for the first one all A,B, and C were wrong we can determine that D is the answer. But wait if I made one mistake and didn't understand if $156.5 is equivalent to $156.50 that would mean A is correct.

Always recheck your answers and good luck,

Jon

The radius of this ball is 15 inches. Which equation gives the ball's surface area, in square inches?
lilavasa [31]

Best to look up the formula for the surface area of a sphere and then find it:

A = 4πr^2, where r is the radius of the sphere.  Then,

A = 4π(15 in)^2 = 4(3.14)(225 in^2) =  2826 in^2 (answer)

This is represented by the formula given in the lower left.
