Answer:
(a) 
(b)300 Hours
(c)150 Hours
(d)Reduced and halved.
(e) 
Step-by-step explanation:
(a) The number of hours worked is inversely proportional to the wage.
This is written as:
(b)If the student earns $8 an hour
w=$8
(c)When the wage per hour =$16
When w=$16
The number of hours reduced and is in fact halved.
(d)
The effect of raising the wage from $w to $2w per hour is that the number of hours required to work is reduced and exactly halved.
(e)The wage per hour is inversely proportional to the number of hours.
In fact,
Answer:
85
Step-by-step explanation:
Volume of cone= pie.r2 h
=1/2*22/7*3^2×9=85
Answer:
The answer to your question is: length = 14 ft; width = 3 ft
Step-by-step explanation:
Data
Area = 42 ft²
length = 8 + 2w
w = width = ?
length = ?
Formula
Area = length x width = l x w
Substitution
42 = (2w + 8)w
42 = 2w² + 8w
2w² + 8w - 42 = 0
Dividing by 2
w² + 4w - 21 = 0 Factorize
(w + 7) (w - 3) = 0
w1 = -7 w2 = 3
It's not possible to have negative widths
So the answer is w = 3 ft
length = 2(3) + 8
length = 6 + 8
length = 14 ft
Answer:
The answer to your question is the letter D. 64π
Step-by-step explanation:
Data
diameter = 8 in
depth = 4 in
Volume = ?
Formula
Volume of a cylinder = πr²h
Process
1.- Calculate the radius
radius = 8 /2
radius = 4 in
2.- Calculate the volume
- Substitution
Volume = π(4)²(4)
- Simplification and result
Volume = π(16)(4)
Volume = 64π
