∆CAT ≅ ∆ ______ by ______

Answers

Answer:

∆CAT ≅ ∆ _____ by cannot be determined

Step-by-step explanation:

If two angles of a triangle are given then a side length is needed too.

The triangles are known to have two of the same angles which automatically makes the 3rd angle equal to the other, but the side length can be any length even when the angles are the same.

The example below shows a picture of what I mean. (credit to mathisfun.com)

They both have the same angles but different side lengths.

Mr. Chang’s class has 28 students, 4 Over 7 of whom are girls. Which equation shows how to determine the number of girls in Mr. Chang’s class?

28 divided by 4 Over 7 = 49
Image with alt text: 28 divided by 4 Over 7 = 49

28 times 4 Over 7 = 16
Image with alt text: 28 times 4 Over 7 = 16

4 Over 7 divided by 28 = 1 Over 49
Image with alt text: 4 Over 7 divided by 28 = 1 Over 49

7 Over 4 divided by 28 = 1 Over 16

Answers

Answer:28 times 4 over 7 = 16Step-by-step explanation:1 - Break down the word problem logically

In Mr. Changs class

there are 28 students in total

4 over 7 = 4/7 = out of every 7 students 4 are girls.

2 - Use mathematical reasoning

To figure out how many girls;

Out of the for every 7 students of the 28 total 4 are girls

With that in mind we'll need to know how many groups of 7 there are which is 28/7

We know now that there are 4 groups of 7 students, so with there being 4 girls in each group, we multiple 4 girls across each group which is 4 x 4

This equals 16

To summarize what I did, I divided 28 by 7 and multiplied that by 4 (How many girls per) which is the same as multiplying 28*4 and dividing that by 7

which is the same as 28 x 4/7

Reasoning

[tex]\frac{28~students}{1~class} * \frac{4~girls}{7~students} = \frac{28~students~*~4~girls}{7~students} = \frac{28~*~4}{7} = 16[/tex]

Step-by-step explanation:

Well first to get to fraction multiply 3/4 by two = so there is 6 /8 of a cup of sugar for every 1/8 of butter so  8X6 = 48 so for every full cup like 8/8 there would be 48/8 cups of sugar or 6 full cups

3/4 x 8 = 24/4 = 6
1/8 x 8 = 8/8 = 1
3/4 : 1/8 = 6 : 1
So 6 cups of sugar is needed for 1 cup of butter.
