Answer:

yes

Step-by-step explanation:

A function is any graph that the x values do not repeat.

You can check this by using this vertical line test

Run your finger or a pencil down a specific vertical (top to bottom) line on the graph, if you can see that it intersects into the graph more than once, then it's not a function.

<h3>Answer:</h3>

99.90%

<h3>Step-by-step explanation:</h3>

STEPS:

  1. Find the total amount
  2. Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
  3. Turn into a percentage by multiplying by 100

Find the total sum

30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total

Find the fraction that small businesses make up of the total

\frac{small~businesses}{total~businesses} = \frac{30,200,000}{30,230,000} = 0.9990

Convert to percentage

0.9990 → % = 0.9990 × 100 = 99.90%

The side lengths in yards of a triangle and a square are shown in the diagram. The perimeter of the triangle is equal to the per
Tatiana [17]

The value of x given the perimeter of the square is 6.

<h3>What is the value of x?</h3>

The first step is to determine the perimeter of the square.

Perimeter of the square = 4 x length

4 x 2.5x = 10x yards

The perimeter of the triangle is equal to the sum of the three side lengths

2x + 4x - 2 + 2x + 14 = 10x

Combine similar terms

14 - 2 = 10x - 2x - 4x - 2x

Add similar terms

12 = 2x

Divide both sies by 2

x = 6

What units could you use to measure the height of a hexagonal prism?
LenaWriter [7]
The answer is centimeters (cm)

Height is 1D dimension so we cannot use cm^2 or cm^3 to measure some distance. With cm^2 we measure surface (because surface is 2D that is why it has this ^2 next to cm) and cm^3 is unit for measuring volume (volume is 3D it has height, width and thickness that is why it has ^3)
cm^4 cannot be the answer since there is no more than 3 dimensions.
