The following numbers ARE functions:

2, 3, 6, 7, 9, 12

Step-by-step explanation:

A function is only possible if the x values have NO REPEATING NUMBER!!!

Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.

Question 1 has the 8 and 4 with 2 numbers.

Question 4 the 3 repeating. (There are 2 dots over the 3)

Question 5 has numbers 1 and 5 repeating many times

Question 8 numbers 1 and 2 are repeated twice

Question 10 number 3 repeats twice

Question 11 has the 1 repeated

Sara is building a triangular pen for her pet rabbit. If two of the sides measure 8 feet and 15 feet, what could the length of t

Aleks04 [339]

As the pen is a triangle, the third side can either be the hypotenuse or a regular side. If the third side is the hypotenuse, it's length would be $l= \sqrt{8^2+15^2} = \sqrt{64+225} = \sqrt{289} =17$ feet. If the third side is a regular side, than it would be $l= \sqrt{15^2-8^2} = \sqrt{225-64} = \sqrt{161}$ ≈12.689 feet. This means your third side can either be 17 feet long or 12.689 feet long.

A hardware store clerk mixed nuts worth $1.32 per kilogram with bolts worth $1.20 per kilogram. If he made 108 kilograms of a mi

AlladinOne [14]

Answer:

the way to work these types of problems is to create a table. The table will have three rows and three columns.

The table:

Let x represent the kilograms of nuts, then 138 - x will represent the kilograms of bolts.

Product Amount Cost Total

--------------------------------------------------------

Nuts x .60 .60 * x

Bolts 138 - x .66 .66 * (138 - x)

Mix 138 .65 .65 * (138)

Step-by-step explanation:

The equation:

The nuts plus the bolts must equal the mix or:

.60 * x + .66 * (138 - x) = .65 * 138

I do not like to work with decimals, so multiply each term by 100:

60 * x + 66 * (138 - x) = 65 * 138

Remove the parenthesis and combine like terms:

-6x = -66 * 138 + 65 * 138

-6x = -138

Divide both sides by -6:

x = 23

Solution:

The mixture contains 23 kilograms of nuts.

The mixture contains 138 - 23, or 115 kilograms of bolts.

Emily read 24 fiction books and 2 nonfiction books. What is the ratio of the number of fiction books she read to the total numbe

Tems11 [23]

The ratio of number of fiction books to total number of books that she read 12:13.

Given :

Emily reads 24 friction books and 2 nonfiction books.

Number of fiction books she read =24

Number of nofiction boos she read = 2

Total number of books = 26

To Find :

What is the ratio of the number of fiction books she read to the total number of books that she read ?

Solution :

Total number of books that she read=24+2=26

number of fiction books she read=24

Thus ratio of number of fiction books to total number of books that she read

⇒ $\frac{24}{26}$

⇒ $\frac{12}{13}$

⇒ 12: 13

Hence ratio of number of fiction books to total number of books that she read 12 : 13
