7/8 = /48 A. 1 B. 6 C. 42 D. 13

1 answer:

6 0

7/8 = x/48

Cross multiply, which is: a/b = c/d ⇒ ad = bc

After cross multiplying, we get:

8x = 7(48)

8x = 336

Divide 8 on both sides

x = 42

Your final answer is B. 42.

There are 26 prize tickets in a bowl, labeled A to Z. What is the probability that a prize ticket with a vowel will be chosen, n

Roman55 [17]

Using it's concept, there is a 0.0308 = 3.08% probability that a prize ticket with a vowel will be chosen, not replaced, and then another prize ticket with a vowel will be chosen. Since the letter is not replaced, the number of outcomes change, hence they are dependent.

<h3>What is a probability?</h3>

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For the first ticket, since 5 out of 26 letters are vogal, the probability is:

5/26.

For the second ticket, since there is no replacement, the probability is:

4/25.

The probability of both tickets is:

$p = \frac{5}{26} \times \frac{4}{25} = 0.0308$

0.0308 = 3.08% probability that a prize ticket with a vowel will be chosen, not replaced, and then another prize ticket with a vowel will be chosen. Since the letter is not replaced, the number of outcomes change, hence they are dependent.

Hey there,

Your question states: Part A-Find the PERIMETER of the outside edges of the frame.

You will do 5+5+7+7 and you will get 24.

Your correct answer would be 24 ft
_____________________________________________________________

Your question states: Find the AREA of the inside of the frame where the picture would belong and the area of the entire frame using the outside values. So I will basically do everything I did for (Part A) but I will do 25 x 35 and this would give me 875.

The area of the frame above would be 875 ft.
_____________________________________________________________

Your question states: If the area of the frame was 64 inches², what would be 2 possible sets of dimensions that could be used to make a frame with that area?

You would do 64/4 because this is a square and a square has 4 sides. So I will do 64/4 and I will get 16.

16 will be your correct answer.
_____________________________________________________________

Your question states: The frame is being enlarged to hang on a gallery wall. Using the scale factor of 1in=2.5ft., give the new dimensions of the outside edges of the frame.

So if each each equals 2.5. I will do 2.5 x 5 and that will give me 12.5. I will also do the same on the other side because this is a square.So that means I will do 12.5+12.5 and I will get 25. Now for the number 7, I will do 7 x 2.5 and that will give me 17.5 but sense its a square I will do the same on the other side and I will get 35. So then I will add 25+35 and I will get 60.

The perimeter of the frame would be 60 ft.

Hope this helps your brain.
