Answer:
π(5²)(13)+⅓π(5²)(12)
Step-by-step explanation:
You can find the volume of the cylinder by:
V=πr²h
which is V1=π(5²)(13)
and the volume of the crooked cone by:
⅓πr²h
which is V2=⅓π(5²)(12)
and you need the volume of the whole shape. you can find by adding V1+V2
Answer:
B.
Step-by-step explanation:
Answer:
The hourly wage is $8.55 per hour
Step-by-step explanation:
Step 1: Determine the expression for the gross pay
Total gross pay=(Unit rate per hour×number of hours(≤40))+(Overtime rate×number of overtime hours)
where;
Total gross pay=$380.48
Unit rate per hour=x
Number of hours=40 hours
Overtime rate=x×(1 1/2)=1.5 x
Number of overtime hours=3 hours
Step 2: Replace to solve for hourly wage
380.48=(x×40)+(1.5 x)×3
40 x+4.5 x=380.48
44.5 x=380.48
x=380.48/44.5
x=8.55
The hourly wage is $8.55 per hour
Answer:
10 seconds
Step-by-step explanation:
Find the zeros by equating f(x) to zero, that is
- 5x² + 50x = 0 ← factor out - 5x from each term
- 5x(x - 10) = 0
Equate each factor to zero and solve for x
- 5x = 0 ⇒ x = 0
x - 10 = 0 ⇒ x = 10
x = 0 denotes the time when the ball is struck and x = 10 when the ball returns to the ground.
Time in air = 10 - 0 = 10 seconds
