Answer:
(11)
Step-by-step explanation:
If it varies directly, you need to find k, the constant of proportionality.
This is done by plugging the values in for x & y that are known.
y = kx
18 = k(5)
= k
Now solve for y when x is 11.
y = (11)
y = 39.6
Answer:
The answer is C.

Step-by-step explanation:
4x − 3= −12x + 13
4x + 12x = 13 + 3
16x = 16
x = 1
Answer: 3,017.5 cubic centimeters.
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of each cd case:
Volume of a rectangular prism= length x width x height
Replacing with the values given:
V = 14.2 x 12.5 x 1 = 177.5 cubic centimeters.
Since there are 17 cases in the stack, we have to multiply the volume one case by 17.
177.5 x 17 = 3,017.5 cubic centimeters.
Answer:
Step-by-step explanation:
40/ 1.5= 20
20/ 1.5= 10
10/ 1.5= 5
5/ 1.5= 3.3
Answer: 3.3

Step-by-step explanation:
Suppose the results obtained are numbers from 1 to 10, then after 10 rolls, the average is
(1+2+3+4+5+6+7+8+9+10)/10
= 55/10
= 5.5
