disa [49]

Answer:

The length of the hypotenuse is 5 inches.

Step-by-step explanation:

The formula for finding the hypotenuse is $a^{2} + b^{2} = c^{2}$ ,

with a and be being the two shorter sides of the triangle, while c is the hypotenuse.

Let's plug in our values for a and b and solve.

$4^{2} + 3^{2} = c^{2}$

16 + 9 = $c^{2}$

25 = $c^{2}$

Jill has $1.25 in her pocket. The money is in quarters and dimes. There are a total of 8 coins. How many quarters and dimes does

erica [24]

Answer:

3 quarters
5 dimes

Step-by-step explanation:

Let q represent the number of quarters (the higher-value coin). Then 8-q is the number of dimes, and Jill's total amount in change is ...

0.25q +0.10(8-q) = 1.25

0.15q + 0.80 = 1.25 . . . . . . . eliminate parentheses

0.15q = 0.45 . . . . . . . . . . . . . subtract 0.80

q = 3 . . . . . . . . . . . . . . . . . . . . divide by 0.15

the number of dimes is 8-q = 8-3 = 5.

Jill has 3 quarters and 5 dimes.
