Answer:
78.5 inch²
Step-by-step explanation:
Given
diameter (d) = 10 inches
radius (r) = 10 / 2 = 5 inches
Area of circle
= πr²
= 3.14 * ( 5)²
= 3.14 * 25
= 78.5 inch²
Answer:
It's c) y = 15x +200
Step-by-step explanation:
First divide the total cost by the number of students using two values of the table:
1500/100 = 15

In the options given, there is just one equation that have 15 multipling x, so that must be the answer
Answer:
The amount of water must be added to this task = 60 
Step-by-step explanation:
Let amount of water added = x 
Then from the given conditions
A chemist would like to dilute a 90-cc solution that is 5% acid to one that is 3% acid. So
90 (0.05) = 0.03 ( 90 + x )
4.5 = 2.7 + 0.03 x
0.03 x = 1.8
x = 60 
Therefore the amount of water must be added to this task = 60
