Answer:
$0.63
Step-by-step explanation:
Raoul saves $14.50 each month for 3 months. Total amount saved is 14.50 * 3 = $43.50
He earned an interest of $0.33.
The total amount of money he has is thus: 43.50 + 0.33 = $43.83
Hector puts $3.60 each week for 12 weeks. Total amount save by Hector is thus 3.60 * 12 = $43.2
Now we are asked to get how much money Raoul has. To get this, we simply subtract the amount of money Hector has from that of Raoul
That would be 43.83 - 43.2 = $0.63
Answer:
4^3
Step-by-step explanation:
4×4×4
Multiply 4 and 4 to get 16.
16×4
Multiply 16 and 4 to get 64.
64=4^3
Answer:
dV/dt = 40π
Step-by-step explanation:
We are told that The radius r(t) of the base of a cone is increasing at a rate of 10 meters per second. Thus;
dr/dt = 10 m
Height: h = 6 m
Volume of cone is given by the formula;
V = ⅓πr²h
dV/dr = ⅔πrh
We want to find the rate at which the volume is changing at radius of 1m.
Thus;
dV/dt = (dV/dr) × (dr/dt)
dV/dt = ⅔π(1 × 6) × (10)
dV/dt = 40π
Answer:
y = 7/2x + 7
Step-by-step explanation:
0 = 7/2(-2) + b
0 = -7 + b
b = 7
y = 7/2x + 7
