Answer:
175 dimes and 75 quarters
Step-by-step explanation:
Make a system of equations, where d is the number of dimes and q is the number of quarters:
d + q = 250
0.1d + 0.25q = 36.25
Solve by elimination by multiplying the top equation by -0.1:
-0.1d - 0.1q = -25
0.1d + 0.25q = 36.25
0.15q = 11.25
q = 75
Then, plug in 75 as q into one of the equations to solve for d:
d + q = 250
d + 75 = 250
d = 175
So, there are 175 dimes and 75 quarters

The total amount of calories burnt in jogging 2 miles = 185 calories
We have to determine the number of calories burned in jogging 3 miles.
Firstly, we will determine the amount of calories burnt in jogging 1 mile. We will use unitary method to evaluate this.
So, the total amount of calories burnt in jogging 1 mile =
= 92.5 calories
So, the amount of calories burnt in 3 miles =
= 277.5 calories
Therefore, 277.5 calories are burned in jogging 3 miles.
Answer:
3/6
Step-by-step explanation:
If the probability that it will happen is 3/6 or 1/2 the probability is the opposite. which is also 3/6 or 1/2.
You have a fraction of 3/2. 3/2=1.5
