If you would like to know the change in Debra's hours, you can calculate this using the following steps:
x% of 16 hours is 22 hours
x% * 16 = 22
x/100 * 16 = 22
x = 22 * 100 / 16
x = 137.5%
137.5% - 100% = 37.5%
22 hours - 16 hours = 6 hours
The correct result would be: an increase of 6 hours, and an increase of 37.5%.
Answer: The dimensions of the frame:.
W= 2√10 or about 6.3245 inches
L= 4√10 or about 12.6491 inches
Step-by-step explanation:
This would be so much easier if the area of the box was 72. Then the dimensions of the frame would be 6 × 12. So just a little bit larger and more complicated.
Here the equation is w(2w)=80
2w^2 = 80 (2w is easier to work with than L/2).
w^2=40 (^2 means squared)
√w^2 = √40 square root of both sides: Factor 40. Take out√4
W = √4*10
W= 2√10
L= 2w = 4√10
6.3245 × 12.6491 = 80
Answer:
y = -0.005x² + 50
Step-by-step explanation:
The diameter is 200 feet, so the parabola has roots at (-100, 0) and (100, 0). The maximum height is 50, so the vertex of the parabola is at (0, 50).
Using vertex form of a parabola:
y = a (x − h)² + k
y = a (x − 0)² + 50
y = ax² + 50
Plugging in either root:
0 = a (100)² + 50
a = -0.005
y = -0.005x² + 50
Answer:
slope is zero equation is y=-3
Step-by-step explanation:
since there is no change in y and they cancel out so you just 0.
Answer: 8,000 Liters
Step-by-step explanation:
There are 1,000 liters in 1 cubic meter. So you would just do 8 times 1,000, which is 8,000 liters.
