Answer:
107.2 seconds
Step-by-step explanation:
Step one:
given
the diameter of ball 8 inches
radius= 8/2 = 4 in
The volume of the ball


Step two:
we know that
rate= quantity/time
rate= 2.4 in per second
quantity= 268.12
time=?
time= quantity/rate
time= 268.12/2.5
time= 107.2 seconds
Answer:
9 quarters
Step-by-step explanation:
From the question
Jesse has $3.40 in quarters and nickels
Quarters = q = number of quarters
1 quarter = $0.25
nickels = n = number of nickels
1 nickel = $0.05
Hence,
0.25q + 0.05n = $3.40 .......Equation 1
The number of nickels is 5 more than 2 times the number of quarters.
n = 2q + 5
0.25q + 0.05n = $3.40 .......Equation 1
0.25q + 0.05(2q + 5) = 3.40
0.25q + 0.10q + 0.25= 3.40
0.35q = 3.40 - 0.25
0.35q = 3.15
q = 3.15/0.35
q = 9
Therefore, Jessie has 9 quarters.
189 inches is 15.75 feet
16 ft - 15.75 ft = 0.25 ft
0.25ft = 3 inches
He must vault 3 inches higher

Answer:
20,9
Step-by-step explanation:
this is how I did=x=1st, y=2nd; x=4y-16 and x+y=29; thus 4y-16+y=29; 5y-16=29; 5y=45; y=45/5=9, once you know y=9, put in equation, 4y-16=×, (4*9)-16=x, 36-16=x, 20=x
