Answer:
I got 65
Step-by-step explanation:
The profit will be given as:
P=$15x−$225
(where we subtracted the cost of the mower) so that P=$750
x will be the required number of needed lawns.
We need to solve:
$750=$15x−$225
rearranging:
x=$750+$225 / $15 =65 lawns
Answer:
137.68

Answer:
The length of DF must be between 21 and 53.
Step-by-step explanation:
In a triangle, the length of two sides added together must exceed the length of the 3rd side. So, since EF is the shortest of the two givens, we know that EF + DF must be greater than DE. So we can plug in these numbers to find the minimum.
EF + DF > DE
16 + DF > 37
DF > 21
Now, for the upper maximum, we know that the two given lengths must be greater than the length of DF. So again, we can solve for the maximum using the amounts.
DE + EF > DF
37 + 16 > DF
53 > DF
With these two in mind, we know that DF must be between 21 and 53
Note that "Complement" = 90°, and "Supplementary" = 180°
Let the complement angle of 32 be x
x + 32 = 90
Isolate the x. Subtract 32 from both sides
x + 32 (-32) = 90 (-32)
x = 90 - 32
x = 58
D. 58° is your complement.
