Step-by-step explanation:
Calculate the area of the base (which is a circle) by using thee equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume. ... Since the volume V of a right circular cylinder is given by V = πr²h.
Which equation can be used to find 75 percent of 200?
(A) StartFraction 75 times 1 Over 200 times 1 EndFraction = StartFraction 75 Over 200 EndFraction
(B) StartFraction 100 times 26.7 Over 75 times 2.67 EndFraction = StartFraction 267 Over 200.25 EndFraction
(C) StartFraction 200 times 2 Over 100 times 2 EndFraction = StartFraction 400 Over 200 EndFraction
(D) StartFraction 75 times 2 Over 100 times 2 EndFraction = StartFraction 150 Over 200 EndFraction

1 yard in 6 minutes
Question 1
Part A
Find the unit rate.
The unit rate in feet per second is 1/120 feet/sec.
Given that, 1 yard in 6 minutes.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
We know that 1 yard=3 feet and 1 minute = 60 seconds
Now, 6 minutes = 360
So, unit rate is 3/360
= 1/120 feet/sec
Therefore, the unit rate in feet per second is 1/120 feet/sec.
#SPJ2
"Your question is incomplete, probably the complete question/missing part is:"

The event coordinator asks you to determine how many students participated in the
track-and-field day. The total number of students in seventh and eighth grade
combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth-graders. If 4/8 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answer:
374.125 students. Not sure if you're supposed to round up or down considering you can't have a fraction of a person, but I would round down.
Step-by-step explanation:
(5/8) (584) = 365 seventh graders in total
(3/8) (584) = 219 eighth graders in total
(4/8) (365) = 182.5 seventh graders who participated in track-and-field day
(7/8) (219) = 191.625 eighth graders who participated in track-and-field day
182.5 + 191.625 = 374.125 students in total who participated
Answer:
First, I took 5/8 out of 584 for the seventh graders which came out to 365 seventh graders. Then, I did the same thing with 3/8 and it came out to 219 eighth graders. Then I took out 4/5 out of 365 which resulted as 292. Then I did the same thing for 7/8 and the results came out as 191. So in total 483 students participated in track-and-field day.
