Answer:
x = 4 when y = 12
Step-by-step explanation:
The ratio of y to x is 6:2. If you multiply either one of them, you must do the same to the remaining number. So, when you multiply 6 by 2 to get 12, you must also multiply 2 by 2 to keep the ratio equal and the same. 2x2 = 4, so x=4 when y=12. Hope this helped! Good luck with other math problems :)
Answer:
127
Step-by-step explanation:
15+38+a=180
a= 127
Multiply total students by the percentage:
600 x 80% = 600 x 0.80 = 480
480 students want more field trips.

Area = πr²
Area = 3.14* 6²
A = 3.14 * 36
A = 113.04
Now find the area of the other one.
<span>Area = πr²
A = 3.14 * 0.75</span>²
A = 1.76625
Now subtract them.
113.04 - 1.76625 = 111.27375
Now, we have our answer: A = <span>111.27375
However, I don't see why they told you to have an exact answer for the area. You can't have an exact answer when you use 3.14 for pi.</span>
