Let's begin by listing out the information given to us:
We start out by observing that Triangles MKR & ACD are similar or proportional
We will solve for the missing side by using the similar triangle theorem. This is shown below:~
Answer:
8.33 hours
Step-by-step explanation:
120-45 = 75
75 ÷ 9 = 8.33
Well we know that the ratio is 2 boys : 4 girls, 2*2=4, if there are 12 boys the ratio would be 12 boys : 24 girls because 12*2=24. Thus, the new ratio is 12 boys : 24 GIRLS
He has 11 quarters, 9 dimes, and 55 nickels.
11x.25=2.75
9x.1=.9
55x.05=2.75
2.75+2.75+.9=6.4
