Answer:
56
Step-by-step explanation:
Let the x be the amount of money Maria had.
3/7 + 1/4 + 1/8 = 45/56
She spend 45/56 of x.
∴ 45/56 × x = (45/56)x
1 - 45/56 = 11/56
(11/56)x is the money that was left.
This is equivalent to 11.
(11/56)x = 11
11x = 11×56
11x = 616
x = 616/11
= 56.
Maria had #56.
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s

Answer:
1.46 cm
Step-by-step explanation:
You have to first convert meters into centimeters to make everything easier. (1m = 100cm)
1.52 meters is 152 centimeters
152-6 = 146 cm
146 cm divided by 100 is 1.46 meters
George is 1.46 meters tall
