irga5000 [103]

Answer:

5 pounds / Make sure to read the explanation so you know how to solve it

Step-by-step explanation:

First thing to do is:

Subtract 90 by 47.10 to find the amount of money she spent

90 - 47.10 = 42.90

She spent $42.90 on coffee and we know that it costs $8.58 per pound so that means that we should divide 42.90 by the cost per pound:

42.90 / 8.58 = 5

She bought 5 pounds of coffee

A trampoline has an area of 49pi square feet. What is the diameter of<br> the trampoline?
Alex17521 [72]

Answer:

The diameter is 14π

Step-by-step explanation:

We know the area of a circle is πr^2

let 49π=πr^2

Cancel the π's, and you get 49=r^2

Take the square root and you get r=7

The diameter of a circle is 2πr.

2π(7)=14π.
