Answer:
A
Step-by-step explanation:
One complete turn is 1 perimeter (aka circumference).
We have to find the length it turned, hence, its circumference.
The formula for circumference (C) of a circle is:

Where r is the radius
The radius is HALF of diameter. Given diameter is 250, the radius is:
r = 250/2 = 125 feet
Now, substituting in formula we have:

So, it turned 785.4 feet with 1 rotation.
The correct answer is A
Answer:
300 students
Step-by-step explanation:
Since 4/5 of students do not wear glasses, 1/5 of students do.
There are 60 students who wear glasses, so let 'x' represent the number of students who wear glasses
(1/5)x = 60 is our equation. "One-fifth of the number of students who wear glasses is 60"
Now solve for x
(1/5)x = 60
x = 300 (multiply both sides by 5 to get rid of the fraction)
$2,500- $60 = $2,440 divided by $35= 69.714 which is rounded to 69 people that can attend the anniversary party
Step-by-step explanation:
Marked price (MP) = x
Selling Price after discount (SP after discount)
= Rs. 1350
Discount rate = 25%
Now
SP after discount = MP - discount % of MP
1350 = x - 25 % of x
1350 = x - x / 4
1350 = 3x / 4
1350 * 4 =3x
5400 / 3 = x
Therefore x = Rs. 1800
The marked price is Rs. 1800
