the circumference is same ratio

60/360=1/6

1/6 of circumference is the legnth of the arc

c=6pi

1/6 of 6pi is pi

ankoles [38]
P(x > 6.9) = 1 - P(x < 6.9) = 1 - P[z < (6.9 - 5.1)/0.9] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275.

Therefore P(x > 6) is about 2.5%

Josh has 4 times as many pears as leya, who has one half as many pears as amy. If josh has 32 pears how many does amy have?
arlik [135]
<h3>The number of pears Amy has is 16.</h3>

Step-by-step explanation:

Let J represent the number of pears Josh has.

Let L represent the number of pears Leya has.

Let A represent the number of pears Amy has.

From the question given above,

Josh (J) = 4 × Leya (L)

J = 4L ....... (1)

Leya (L) = ½ × Amy (A)

L = ½A ........ (2)

Next, we shall determine the number of pears Leya has. This can be obtained as follow:

From equation 1

J = 4L

But

Josh (J) = 32 pears

Thus,

32 = 4L

Divide both side by 4

L = 32 / 4

<h3>Leya (L) = 8 pears </h3>

Finally, we shall determine the number pears Amy has. This can be obtained as follow:

From equation 2

L = ½A

But

Leya (L) = 8 pears

Thus,

8 = ½A

Cross multiply

A = 8 × 2

<h3>Amy (A) = 16 pears </h3>

Therefore, Amy has 16 pears.

A local concert promoter purchases 2 3/4 pages of ads. When one of the concerts is cancelled, the promoter cancels 1 5/8 pages o
Lynna [10]

Answer:

1\frac{1}{8} pages

Step-by-step explanation:

Since the concert promoter started with 2 \frac{3}{4} pages of ads but had to cancel 1 \frac{5}{8}, subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:

 2 \frac{3}{4}  = 2 \frac{6}{8}

- <u>1 \frac{5}{8}</u>      - <u>1 \frac{5}{8}</u>

     1\frac{1}{8} pages

In order to subtract fractions, you need to have like denominators, so you need to convert \frac{3}{4} into an equivalent fraction with a denominator of '8'.  Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.
