1 dozen eggs = 12 eggs
1.35 / 12 = 0.1125.....so the unit cost = $ 0.11 (11 cents) per egg
Answer:
b=1
Step-by-step explanation:
<u>First, let's regroup, terms,</u>
<u>Add 11 to both sides,</u>
<u>Simplify, 7+11 = 18,</u>
<u>Now, divide both sides by 3,</u>
<u>Simplify, 18/3 = 6,</u>
Subtract 5 from both sides,
Hope it helps! :)
Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
First, we will establish that the shape of the window is a semi-circle. This means we must use the formula for the perimeter of a semi-circle to obtain the perimeter of the window.
The formula for the perimeter of a semi-circle is as follows:
Let perimeter of window or semi-circle = P
P = [ 2( Pi )r / 2 ] + 2r
Where r = radius of circle or semi-circle
From this, we will simply use the value of the radius given from the diagram in the problem and substitute it into the formula to obtain the perimeter of the window.
P = [ 2( Pi )r / 2 ] + 2r
r = 20
THEREFORE:
P = [ 2( Pi )( 20 ) / 2 ] + 2( 20 )
P = 20( Pi ) + 40
P = 102.83...cm^2
P = 102.8cm^2 ( to the nearest tenth )
FINAL ANSWER:
Therefore, the perimeter of the window is 102.8cm^2 ( to the nearest tenth ).

Have a lovely day! <3
Answer: 20 hours
Step-by-step explanation: We want to round our answer to the nearest hour, we know that the rocket can travel 200 miles per 1 minute, but we want to know first how many miles the rocket can travel per 60 minutes or 1 hour.
To find how many miles the rocket can travel at 60 minutes or 1 hour, simply multiply 200 x 60. 200 x 60 = 12,000 miles per hour.
Now, we want to find how many hours it would take for the rocket to travel from the earth to the moon.
Simply divide 239,000 by 12,000 to get the amount of hours it would take to reach the moon. 239,000/12,000 = about 20 hours.
So, it would take the rocket ship 20 hours to reach the moon from the earth.
so 1.25 is the right answer not sure tho
