8. myles had 103 coins in a jar - all nickels, dimes, and quarters. if the total value of the coins is $15
Ivanshal [37]

If the total value of the coins is $15. The number of each type of coin is: 31 quarters, 72 dimes.

<h3>Number of each type of coin</h3>

Let D = number of dimes

Let Q = the number of quarters

Equations

d + q = 103

0.10d + 0.25q = 15  

d = 103 -q

0.10(103 -q) + 0.25q = 15

10.3 - 0.10q + 0.25q = 15

0.15q = 4.7

q=4.7/0.15

q=31 quarters

Substitute q into second equation

D+31=103

D=72 dimes

Therefore the number of each type of coin is: 31 quarters, 72 dimes.

First of all you have to use the formula

a^2+B^2=c^2
a=6   b=4   c=?

6^2+4^2=?
36+16=?
after you add 36 and 16 find the square root
the square root of 52 is 7.211
if you don't want it in decimals you can just put it like this <span>sqrt(52)</span>
