Step-by-step explanation:
<u>Steps to answering this question </u>
- determine how many eggs would be required to make one cookies
- Multiply the answer gotten above by the number of cookies
Number of eggs needed for one cookie = 4/30 = 0.1333

Answer:
Perimeter = 36.8 ft
Step-by-step explanation:
<u>Step 1:  Add the straight sides together</u>
3+3+3+3+3+3 = 18 ft
<u>Step 2:  Find the perimeter of the semi-circles</u>
The formula for the perimeter of semi-circle:  1/2 π × d
Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.
Now, 1/2π * 6 = 9.4 ft
But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft
<u>Step 3:  Add all of them</u>
18 + 18.8 = 36.8 ft

Answer:
$1.20
Step-by-step explanation:
Ratio:
Grams : Kilograms
1 : .001
Multiply both sides by 20 to convert grams to kilograms:
Grams : Kilograms
1 : .001
x20 x20
20 : .02
This means that 20 grams of lead = .02 kilograms of lead
Price:
Cost : Kilogram
$60 : 1
Multiply both sides by .02 to find the price of the lead:
Cost : Kilogram
$60 : 1
x.02  x.02
$1.20 : .02
Therefore, .02 kg of lead costs $1.20.
