Square of longest side = 17^2 = 289
15^2 = 225
13^2 = 169
total 394 289 is less than this so its acute
Answer:
There are 24 dimes
Step-by-step explanation:
we can make an equation and then solve it to find our answer.
n = number of nickles at $0.05 each
4d = number of dimes at $0.10 each
(0.5)n + (0.10)(4n) = 5.40
We now solve this
First, multiply
0.5d+0.4d=5.40
then add
0.9d=5.40
then divide
D=6
Then, multiply by four since there are four times as many dimes
6x4=24
There are 24 dimes
