<h2><u>Answer:</u></h2><h3>6.) \boxed{A}</h3><h3>7.) \boxed{D}</h3><h2 /><h2><u>Solution Steps:</u></h2>

______________________________

<h3>6.) Solve each problem:</h3>
  • 3 ÷ 8=0.375
  • 4 ÷ 12=0.333333333
  • 2 ÷ 6=0.333333333
  • 10 ÷ 30=0.333333333

 - So looking at this most of them equal 0.333333333, which in fraction form is \frac{1}{3}, so 3 ÷ 8 must be the answer.

<h3 /><h3>7.) Solve each problem: </h3>
  • 25 ÷ 8=3.125
  • \frac{25}{8}=3.125
  • 3\frac{1}{8}=\frac{25}{8}=3.125
  • 8 ÷ 25=0.32

<em>  - So looking at each problem answer, most of them are 3.125, except for 8 ÷ 25.</em>

Hi, can you please help me answer this direct proportion question?
Oksanka [162]

Answer:

X = 100

Step-by-step explanation:

  • In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
  • This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.
  1. Multiply the left by k, so y = \frac{k}{\sqrt{x} }
  2. we know that y= 5, for x = 36, so sub this in the equation
  3. 5 = \frac{k}{\sqrt{36} }
  4. simplify5 = \frac{k}{6 }
  5. re-arrange for k, <u>k = 5*6 = 30</u>
  6. now we know k, we can create the real equation, y = \frac{30}{\sqrt{x} }
  7. sub in 3 as y
  8. 3 = \frac{30}{\sqrt{x} }
  9. <u>x = 100</u>

Please help me! I will give brainliest and 50 points if all correct!
miss Akunina [59]

Answer:

10. ○\displaystyle 4,85; 4\frac{17}{20}

9. ○680%

8. ○40%

7. ○\displaystyle 60

6. ○0,4, 40,5%, 11⁄25, 4⁄9

5. ○\displaystyle 0,928

4. ○1%

3. ○76%

2. \displaystyle See\:above\:grid

1. \displaystyle See\:above\:grid

Step-by-step explanation:

10. To convert from a percentage to a decimal, move the decimal mark twice to the left; each 20 is worth 5, and since 5 by 17 is 85, you have your fractional part of 17⁄20, then attach the whole number of 4.

9. To convert from a mixed number\improper fraction to a percentage, first evaluate the fractional part for a decimal answer, then move the decimal mark twice to the <em>right</em>.

8. To convert from a fraction to a percentage, evaluate the fraction for a decimal answer, then move the decimal mark twice to the right.

7. \displaystyle \frac{132}{220} = \frac{3}{5} =60%

Greatest Common Divisor [GCD]: 44

6. \displaystyle \frac{11}{25} =44%

_

\displaystyle \frac{4}{9} =44,4%

\displaystyle 0,4 =40%

Now that these are all percentages, it is alot easier to order them from least to greatest.

5. To convert from a percentage to a decimal, move the decimal mark twice to the <em>left</em>.

4. To convert from a decimal to a percentage, move the decimal mark twice to the <em>right</em>.

3. Each 25 is worth 4, and since 4 by 19 is 76, you get 76%.

2. Each 25 is worth 4, and since 4 by 6 is 24, you get 24%, and this graph.

1. Each 36 is worth 2 7⁄9, and since 12 by 2 7⁄9 is 33⅓, you get 33⅓%, so you would choose this answer.

I am joyous to assist you anytime.
