Answer:
9 boys
Step-by-step explanation:
15/5
=3
3*3
=9
Using equation of motion.
S = ut + (1/2)gt²
Where S = Height, t = time, g = acceleration due to gravity = 9.8 m/s²
time, t = 8 seconds
Since it was dropped from height, initial velocity, u = 0
S = 0*t + (1/2)gt²
S = (1/2)gt²
S = (1/2)*9.8*8² = 4.9 * 8 * 8 = 313.6
Therefore the ledge is 313.6 m tall.
Answer:
A. The product is equal to 743.
B. The product is less than 107.
C. The product is more than 647.
Step-by-step explanation:
If both sides of the fraction are equal it is equal, if the top is higher it is greater and if the bottom is greater then it is less. Btw I mean greater than the other side of the fraction.
4m + 9 + 5m - 12 = 42
9m + 9 -12 = 42
9m -3 = 42
9m = 42 + 3
9m = 45
m= 45/9
m= 5
Answer is C.
