Answer:
second choice is the answer
Step-by-step explanation:
8•20=q. Multiply the number of piles by the number of quarters in each pile: 8•20=160, there were 160 quarters. Now to find how much they made multiply the number of quarters by how much 1 quarter is: 160•.25=40 they made $40 :)
What is the measure of arc ADB?
The measure of the arc for this case is given by the following angle:
theta = 360-90
theta = 270 degrees
What is the length of arc ADB?
The arc length is given by:
s = R * theta
Substituting values:
s = 15 * (270 * (pi / 180))
s = 70.69 m
What is the area of the shaded region?
The area of the shaded region is:
A = (s' / s) * (pi) * (r ^ 2)
Substituting values:
A = (270/360) * (3.14) * (15 ^ 2)
A = 529,875 m ^ 2
Answer:
11.25 yards
Step-by-step explanation:
The first thing we must do is see what the volume of the tank would be, which due to the measurements they give us would be:
v = height * width * length
We are asked to calculate the length, therefore:
length = v / (width * height)
volume equals 525, width 16 2/3 (16.67) and height 2 4/5 (2.8), replacing:
length = 525 / (16.67 * 2.8)
length = 11.25
Which means that the length is 11.25 yards
