Answer:

D

Step-by-step explanation:

We can find the answer by comparing the sides of the triangles!

We are trying to find a triangle where the ratios are the same: 4/9 has to equal another fraction.

Triangle D is correct because 12/27=0.4 which is equal to 4/9=0.4

another way we can check is by seeing how much 4 is multiplied to get to twelve and seeing how much 9 is multiplied to get to 27

4*3=9

9*3=27

by this we can confirm the fractions of 4/9 and 12/27 are equal because both 4 and 9 are multiplied by the same number to get to the new fraction numbers.

hope this helps!

The wind blew away 24 of your muffins. That was 3/4 of them! How many are left?
forsale [732]
Set up a proportion:

3/4/24 = 1/x

Cross multiply:

3/4x = 24

Divide 3/4 to both sides or multiply by its reciprocal, 4/3:

x = 24 * 4/3

x = 96/3

x = 32

So you had a total of 32 muffins, now subtract this from the amount that blew away to find out how many you have left:

32 - 24 = 8

So you have 8 muffins left.

Someone help please haha​

Answer:

{-8, -7, 0, 6, 9}

Step-by-step explanation:

1. The range of a relation is the set of its possible output values, also known as the y-values of a function.

2. Let's find the y-coordinate of each point.

  • 9, 6, 0, -7, -8

3. Now, let's order them (from least to greatest) to get the range.

  • -8, -7, 0, 6, 9
  • {-8, -7, 0, 6, 9}

Therefore, the range of this relation is {-8, -7, 0, 6, 9}.
