90 minus 35 = 55
Cause that is a right angle which = 90 degrees
Answer: 12 minutes per mile
Step-by-step explanation: 20 miles) / (4 hours) = (20/4) (miles/hours) = 5 miles per hour
(4 hours) / (20 miles) = (4/20) (hours/miles) = 0.2 hours per mile
Answer: Option C: 44
Step-by-step explanation:
so, here we have the equation:
H(a,b) = 2a + 4b
"evaluate" means change the values of the variables for specific values, here we must replace the "a" for 10, and the "b" for a 6.
So we have:
H(10, 6) = 2*10 + 4*6 = 20 + 24 = 44
So,
If we visualize it, we can see a 3 x 3 square, with each unit representing 2 in.
If we do simple multiplication, we can figure out that each side is 6 in. long.
Fourfold of 6 in. reveals the perimeter: 24 in.
