Answer:
18/44
Step-by-step explanation:
To turn 9/22 into something over 44, we need to figure out what to multiply it by.
44 / 22 = 2.
Multiply 9/22 by 2:
9/22 * 2 = 18/44
15/6=2.5 which is the scale factor since they are similar triangles. We divide each side of the large triangle by 2.5 to get the sides for the small triangle since they are similar. 20/2.5=8cm
25/2.5=10cm
For the second problem, you put 15/6 and set in equal to x/8 when you cross multiply you get 6x=120 then you divide x=20
For the last problem, you divide 43,75 by 5 then multiply it by 400 to get the kiloliters which equals 3,500.
Volume of a cylinder is defined as:
v = volume
r = radius
h = height.
V = 
(r^2)h
In this problem,
v = 1,356.48 in^3
r = 6 in
h = ?
Plug our numbers into the volume formula above.
1,356.48 in^3 = (6^2)h
Divide both sides by (6^2) to isolate variable h
12.0 = h
The height of the cylinder is 12.0 inches
Direct variation equal is written as : y = kx
K is the constant of variation.
12 = k4
12/4 = k
k = 3
y = 3x
Answer: <span>B. y = 3x </span>
Answer:
1
Step-by-step explanation:
Since 12 / x = 4, you can safely assume that you would need to divide the 3 by x as well.
12 / 3 = 4
x = 3
3 / 3 = 1
Therefore, the answer is 1.
