There are always two possible unit rates.
Either way, you just divide to find it.
(5 hours) / (216 miles) = 0.023 hours per mile .
(216 miles) / (5 hours) = 43.2 miles per hour .
Answer:
537.2 ft^2
Step-by-step explanation:
For this problem, we need to find the area of both the inner and outer circle and subtract the area of the outer circle from the area of the inner circle.
The equation for the area of a circle is:
A = πr^2
So we are given the diameters of the circles. We know that the diameter of a circle is twice the radius.
Let's find the area of the 10ft diameter circle:
A_Little = π(10/2)^2 = π(5)^2 = 25π
Let's find the area of the 28ft diameter circle:
A_Big = π(28/2)^2 = π(14)^2 = 196π
So the area of the big circle excluding the inner circle would be as follows:
196π - 25π = 171π
So 171π in terms of decimals rounded to the nearest tenth would be 537.2.
Cheers.
Answer:
D for the first one A for the second
For this case, we must build a quotient that, when multiplied by the divisor, eliminates the terms of the dividend until it reaches the remainder. In this case we have to:
Remainder: 20
Quotient: 3x-9
It must be fulfilled that:
Dividend = Quotient * Divider + Remainder
