Will mark brainliest for area.
Elena L [17]

Answer:

c

Step-by-step explanation:

first, find the area of the rectangle thing,

A = lw

14 x 8

112

but, there is a semicircle in it so you need to subtract that from it:

A = πr^2/2

A = π(4)^2/2

A = π16/2

A = 8π

A ≈ 25.132741228718346

then subtract that area from the area of the rectangle:

112 - 25.132741228718346

86.867258771281654

or about 89.9

Question 1: An online music store is offering a promotion. When you spend $30 or more, you receive 3 songs for free. You buy an
ch4aika [34]

Answer:

10 + m  ≥ 30

You must spend AT MOST $20 or more

Step-by-step explanation:

Basically you have already spent 10 dollars and you have to pay MORE than or equal to 30. You cannot pay less than because you want the free songs. So the sign has to be  ≥ or the inequality will not be true.

10 + m  ≥ 30

10 - 10 + m  ≥ 30 - 10     ( subtract 10 from each side to isolate m)

m  ≥ 20     ( we are left with this )

The answer is :

m  ≥ 20

You must spend at most 20 dollars more to get the 3 free cd's. Your welcome :D
