Answer:
59.99 minutes
Step-by-step explanation:
4 hours divided by 28 mins = 8.57142857 (rounded to 8.57)
7 x 8.57 = 59.99.
If you would like to solve the following equations, you can calculate it using these steps:
1) x% of 125 cm is 87.5 cm
x% * 125 = 87.5
x/100 * 125 = 87.5 /*100/125
x = 87.5 * 100 / 125
x = 70%
2) y% of 132 days is 125.4 days
y% * 132 = 125.4
y/100 * 132 = 125.4 /*100/132
y = 125.4 * 100 / 132
y = 95%

Answer:
Step-by-step explanation:
The vertex is the point at which the parabola or quadratic equation opens up or down. To calculate the parabola, we must use the formula: -b/2a = x; x = -16/2(4) x = -2
Substitute -2 in where you see x appear and do the arithmetic to find that y = -15. Therefore, the vertex coordinates are (-2,-15).
