I would say the answer is : C ) 3 to 5.
Since we know that all angles in a triangle add up to 
, we can solve for 
and substitute it back into 
to find 
.
Remove the parentheses and combine like terms.
Add 
to both sides of the equation.
Divide both sides of the equation by .
Now that we have the value of , we can substitute it back into to find .
10$ an hour so they are making $2.50 every 15 minutes
a) 3 1/4 pounds of apple costs $6.46
b) X pounds of apple costs $1.99X
c) Clare bought 2.59 pounds of apple
Step-by-step explanation:
Cost of apple per pound= $1.99
a) 3 1/4 pounds = 13/4 pound
Cost for 13/4 pounds of apple = 1.99(13/4)
= $6.46
b) cost for X pound = 1.99(X)
=$ 1.99X
c) money spent for apples = $5.17
Cost per pound = $1.99
Total weight of apple bought = 5.17/1.99
= 2.59 pounds of apple
Surface area = πr² + πrl
Surface area = π(3)² + π(3)(7) = 94.25 in² (nearest hundredth)
