Answer:

<h2>421.</h2>

Step-by-step explanation:

If 47% of the pages include her twin sister, Bethany, we just need to obtain that percentage from the total 896 photos.

896\frac{47}{100} = 421,12.

Hence, 421 is the amount of photos of her.

 you do 47%/100% and X/896 and cross multiply . so 47 times 896 =  42112 and divide that by hundred so the answer should be 421 photos.

A department store is having a sale in which every item is 38% off its original price. The regular price of a suit is $112. How
lara [203]

Answer: $42.56

Step-by-step explanation:

Percent discount in department store = 38%

The regular price of suit = $112.

Price taken off the regular price of the suit =

38% of $112

So, 38% of $112

= (38/100) x $112

= 0.38 x $112

= $42.56

(i.e the customer will pay $112 - $42.56 = $69.44 only for the suit)

Thus, the price taken off the regular price of the suit is $42.56

Hello!

The formula for circumference is 2\pi r and the formula for area of a circle is \pi r^{2}. Armed with these formulas, we can begin to find the circumferences and areas of the circles.

20. 
C = 2 \pi r
C = 2 \pi (6.5)
C = 13 \pi
C = 13(3.14)
C = 40.8

A = \pi r^{2}
A = \pi (6.5)^{2}
A = \pi (42.25)
A = 132.7

The circumference of the circle is 40.8 in and the area of the circle is 132.7 in².

21.
[Since we are given the diameter for this problem, to find the circumference, we no longer need to multiply the radius by 2 as in 2 \pi r because the diameter is the radius × 2. For \pi r^{2} we do need to divide the diameter by 2.]

C = 15.7 \pi
C = 49.3

A = \pi r^{2}
A = \pi (7.85)^{2}
A = 61.62 \pi
A = 193.5

The circumference of the circle is 49.3 in and the area of the circle is 193.5 in².

And that is all there is to it. I hope this helps you! (:
