Line AB is parallel to line CD. What is the measure of angle CFE?

A 45°
B. 55°
C. 125°
D. 180°

Answers

Answer: c

Step-by-step explanation:

A full circle is 360 degrees so half way would be 180 and since theyre parallel you know that you can use the 55 degrees up top to use in ur equation to find cfe

180-55=125

Can't be 45 because the angle on the other side is smaller than cfe and its 55 degrees and cfe has to be wider than 90 degrees because a right angle is 90 degrees and this angle noticeable goes past 90

Can't be 180 because the whole thing equals 180

) Suppose you are installing a wood floor in a square room. The cost to install the floor is $9 per square foot. The area of the room is given by the function A(x) = x 2 and the cost per square foot is given by the function C(A) = 9A. Which function can be used to find the total cost to install the wood floor? A) A(C(x)) B) C(A(x)) C) x(A(C)) D) x(C(A))

Answers

Answer:

The correct option is;

B) C(A(x))

Step-by-step explanation:

The given information are;

The cost to install the floor per square foot = $9

The area of the room is given by the function A(x) = x²

The function for the cost per square foot = C(A) = 9·A

We note that the total cost to install the wood floor = (The cost to install the floor per square foot) × (The area of the room)

∴ The total cost to install the wood floor = $9 × x²

Given that A(x) = x², we have;

The total cost to install the wood floor = $9 × A(x)

Also, given that C(A) = 9·A, we have;

C(A(x)) = 9·A(x)

Therefore;

The total cost to install the wood floor in dollar amount can be given by the function, C(A(x)) = 9·A(x)

Two​-thirds of the​ T-shirts in a​ T-shirt shop are blue. Three​-fifths of those​ T-shirts are on sale. ​One-half of the blue​ T-shirts that are on sale are size medium. What fraction of the​ shop's T-shirts are blue​ T-shirts that are on sale and are size​ medium? Explain.

Answers

Let, total number of T-shirts are x.

Number of blue T-shirts = (2/3)x = 2x/3 .

Number of blue shirts on sale = (3/5)(2x/3) = 2x/5 .

Number of medium sized blue shirts on sale = (1/5)(2x/5) = 2x/25 .

Fraction of the​ shop's T-shirts are blue​ T-shirts that are on sale and are size​ medium = [tex]\dfrac{2x/25}{x}[/tex]= 2/25 . ( Number of medium sized blue shirts on sale divided by total number of T-shirts )

Hence, this is the required solution.

What is reciprocal of the number 5

Answers

Answer:

1/5

Step-by-step explanation:

5 = 1/5

6= 1/6

1/6= 6/1 (or just 6)

5/6= 6/5

Do you see the pattern?

Every number has a reciprocal except for 0. There is nothing you can multiply by 0 to create a product of 1, so it has no reciprocal.

Answer:

1/5.

Step-by-step explanation:

When referring to a reciprocal, it basically means taking the numerator and the denominator and flipping them.

For example, take 4/5. The reciprocal of 4/5 would be 5/4.

Now, take 5. As a fraction, it would look like 5/1. If you were to flip it, it would be 1/5.

Therefore, the reciprocal of 5 is 1/5.
