42 is 87.5% of what number

Answers

Answer:48

Step-by-step explanation:

Answer:

Step-by-step explanation:

42 = 87.5% x Y

42 = 87.5 x Y

100

Multiplying both sides by 100 and dividing both sides of the equation by 87.5 we will arrive at:

Y = 3 x

100

87.5

Y= 48

If there are 36 performer's in a dance recital and the ratio of men and women are 2:7.How many of the men where performer's??????????????????????

What is the arc length of an angle of 7pi/6 radians formed on the unit circle?A) pi/6

B) 5pi/6

C) 7pi/6

Answers

Arc length is7 pi / 6.The distance between two places along a segment of a curve is known as the arc length.

How do you calculate the arc's length?

Using the formula Length of an Arc = r, where is in radians, one may determine the arc length of a circle given its radius and central angle. Arc length is equal to (r/180), where r is the radius in degrees.

The distance between two places along a segment of a curve is known as the arc length.

Remember that an arc is a section of a circle. The use of degrees is one method of arc measurement. An arc's length is equal to the length of the center angle it corresponds to.

Detailed explanation:

Angle * Radius = Arc Length (in radians)

arc length equals 1/7 pi/6

arc length = 7 pi / 6.
