**Answer 1**

**Answer:**

**Start:**

Percentage with pelvic spines = 94.4%

Percentage without pelvic spines = 5.6%

**End:**

Percentage with pelvic spines = 61%

Percentage without pelvic spines = 39%

**Explanation:**

For both of these, you just need percentage. To find that for both, you just divide the value you want by the total value and then you multiply that result by 100. This will give you the percentage.

So you see, if you divide a number smaller than 1, but bigger than 0, you get a number larger than the original one. So a method to prove that is multiply both sides by 100 and you get 909.5/17 which is 53.5

**Step-by-step explanation:**

The raspberries cost 1.53 dollars more than the strawberries per pound.

If the grocery store charges $9.50 for 2 pounds of strawberries, we must divide 9.50 by 2, which equals 4.75.

Comparing 4.75 (the cost of strawberries per pound) to 3.22, (the cost of raspberries per pound), we find that the difference between the two numbers is 1.53z

### Answers

**Answer:**

If you mean the sum of internal angles of the n-gon is 6 right angles,

we use the formula 180*(n-2) = 6*90

or n-2 = 6*90/180

or n - 2 = 3

or n = 5

So it is a pentagon or 5-gon

### Answers

There are 2 ways to do this. I'm going to do it the way that I think is most simple.

You have to find their LCM which is 40. Now times 40 to 1/4 v and 7/10

The equation then becomes 10+40v=28

You simplify it: 40v=18

v= 9/20

**Answer:**

v = 9/20

**Step-by-step explanation:**

1/4 becomes 10/40

7/10 becomes 28/40

28/40 - 10/40 = 18/40

simplify 18/40 divided by 2

v = 9/20

### Answers

what's up? we can use the following formula:

(leg)^2 + (leg)^2 = (hypotenuse)^2 to get 6, 8, 10 as your answer

6^2 + 8^2 = 14^2

36 + 64 = 196?

100 ≠ 196

6^2 + 8^2 = 10^2

36 + 64 = 100?

100 = 100

3^2 + 5^2 = 6^2

9 + 25 = 36?

34 ≠ 36

7^2 + 12^2 = 13^2

49 + 144 = 169?

193 ≠ 169

let's firstly convert the mixed fraction to **improper fraction** and then multiply.

Hey there!

3/4 * 2 1/2

= 3/4 * 5/2

= 3(5) / 4(2)

= 15/8

≈ 1 7/8

Therefore, your answer is:

15/8 or 1 7/8

EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT TO EACH OTHER!
