Answer:
50 muffins
Step-by-step explanation:
20 : 40%
y : 100%

y · 40 = 20 · 100
40y = 2000
40y ÷ 40 = 2000 ÷ 40
y = 50
Answer:
V = 15 in.³
Step-by-step explanation:
The original cylinder has radius r and height h.
V = πr²h
Its volume is 30 in.³, so
πr²h = 30 in.³
The new cylinder has radius (1/2)r and height 2h.
Its volume is
V = π(r/2)²(2h)
V = πr² × 2h/4
V = πr²h/2
πr²h is the volume of the original cylinder, and it is 30 in.³.
V = 30 in.³/2
V = 15 in.³
Answer:
Step-by-step explanation:
You start off by rewriting the equation:

Then you have to factor:

Then you subtract the 0.2x:

Add the positives on the right:

Add 14:

Divide:

You get x is approximately equal to 10.84
Answer:
31 days
Step-by-step explanation:
125 kg/1 day = 3875 kg/x days
x(125) = 3875
x = 3875/125
x = 31 days
Answer:

Step-by-step explanation:

Step 1. Switch sides.

Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.


Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.
