The percentage that the number of airlines with an average airplane age of 14 is less than the number of airlines with an average airplane age of 11 is:
B. 20%.
<h3>What is a percentage?</h3>
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

The percentage of airlines with an average age of 14 years is:

The percentage of airlines with an average age of 11 years is:

The difference is:
33.33% - 13.33% = 20%.
Hence option B is correct.

Well first of you need to know that on a straight line there should be 180 degrees. Also a triangle has 180 degrees in total. Now if this is to scale then you can always measure the angle BCA and explain how you took that away from 180 to get whatever. Assuming otherwise i don't know how one can actually complete this question without any measurements, at least one and it would be something anyone can complete. Even if you didn't have anything it should be a equilateral triangle or isosceles. That way you can work out the inside sides than the exterior. But since it's not, I'm not to sure.
Answer:
$34
$26.5
Step-by-step explanation:
Membership cost per month = $25
Price of a slice of pizza for members= $1.50
How much would Aaliyah have
to pay the pizza shop if she bought 6 slices of pizza this month
Total cost of Aaliyah on 6 slices of pizza = membership cost per month + prices of 6 discounted pizza
= $25 + $1.50(6)
= $25 + $9
= $34
What would be the
monthly cost for a slices of pizza
Monthly cost of Aaliyah a slices of pizza = membership cost per month + price of 1 discounted pizza
= $25 + $1.5
= $26.5
The will spend $33.60 (option C) to make the figure out of construction paper, if the construction paper cost $0.10 per square inch.
Step-by-step explanation:
The given is,
Construction paper cost $0.10 per square inch
Pyramid diagram with dimensions
Step:1
Formula to calculate the area of pyramid,
..............(1)
Where,
l - Base length
w - Base width
h - Height of pyramid
From given,
l = 12 inches
w = 12 inches
For height of pyramid,
By using Pythagorean theorem,
.................(2)
For right angle triangle,
Base =
= 6 inches
Equation (2) becomes,




Height = 5.2915 inches
h - 5.2915 inches
Equation (1) becomes,




≅ 336 square inches
Where,
$0.10 per square inch ( from given)
Paper cost of total figure = 336 square inches
= 336 × 0.10
= $ 33.60
Result:
The will spend $33.60 to make the figure out of construction paper, if the construction paper cost $0.10 per square inch.
