Answer:
18 yds
Step-by-step explanation:
Let the length and width be L and W respectively.
Then L· W = area = 72 yd², so that L = (72 yd²) / W.
But also L = 3W + 6 yd. Subbing this into L· W = area = 72 yd², we get:
(3W + 6) · W = 72, or
3W² + 6W - 72 = 0. Since all four terms are evenly divisible by 3, we get:
W² + 2W - 24 = 0, which factors as follows:
(W + 6)(W - 4) = 0. Then W + 6 = 0, or W = -6 (makes no sense for a length), and W - 4 = 0 yields W = 4 yds.
If the shorter side is of length 4 yds, then the longer side is of length
L = 3(4 yds) + 6 yds = 18 yds
It would be 1.3 less than the other.
L’oreal’s car can gets better mileage because you have to divide both the miles and the amount of gallons they carried. L’oreal: 420 divided by 14 is 30 = 30 miles per gallon. Laila: 435 divided by 15 = 29 miles per gallon. But since we have to even out the amount of gallons they both carry, we can either take away 29 to the 435 (Laila), or add 30 to the 420(L’oreal). 420 + 30 = 450. 435 - 29 = 406. 420 > 406 = 450 > 435. L’oreal has the better mileage
Answer:
33.7º
Step-by-step explanation:
tan = opp/adj
tan∅ = 100/150 = 2/3
∅ = arctan 2/3
∅ = 33.690067525979787
33.7º
0 if it is parellel to the x axis then the slope is 0
