She would need to work for 35 hours.
She earned $250.25 total the first two weeks, so divide that by the new rate per hour, $7.15, to get the 35 hours.
Answer:
the first one is 3.74 and the second one is 6%
its basic percent subtraction
Step-by-step explanation
We know that the area is 20.
Since 20 is a small number: lets list out possible combinations of lengths and widths.
1 * 20
2 * 10
4 * 5
L = 7 + 3w
lets see which on makes sense.
L = 7 + 3w
20 = w7 + 3w^2
3w^2 + 7w -20 = 0
(3w - 10)(w - 2)
w can equal 10/3 or 2.
So the dimensions: are Width = 2 Length = 10
The answer should be b¹². You add the exponents of each constant. In the case of the simple b the exponent would be one.
Y = 2x + 0.5
or
y = 2x + 1/2
