Answer:
D. Scalene triangle
Step-by-step explanation:
This right triangle is a scalene triangle because all the three sides are of different lengths.
i.e 17.6 units, 25.1 units and 30.7 units are all different.
10 x 523.6 inches = 5236 inches.
5236 inches is equal to 0.08262311 miles.
Answer:
Quarters = 10
Dimes = 15
Step-by-step explanation:
d = number of dimes, q = number of quarters
d + q = 25 is the equation for number of coins
0.1d + 0.25q = 4 is the equation for value of coins
First, solve for d in terms of q:
d + q = 25
d = 25 - q
Then substitute that into the other equation:
0.1(25 - q) + 0.25q = 4
2.5 - 0.1q + 0.25q = 4
0.15q = 1.5
q = 10
And back to d = 25 - q, d = 25 - 10 = 15
Check the math:
0.1(15) + 10(0.25) = 1.5 + 2.5 = 4
