Ugentttt Identify each ratio as proportional or not to ratio 3:7

Mathematics
1 answer:
Aloiza [94]3 years ago
6 0

Answer:

1. Not proportional

2. Proportional

3. Proportional

4. Not proportional

Step-by-step explanation:

A trick I used was to divide 3 by 7 and I got around 0.42.

Then I proceeded to type the fractions into the calculator to see which ones gave me 0.42.

Example: 12 divided by 28 is equal to about 0.42 so it is <u>proportional</u>

24 divided by 54 is not 0.42 so it is <u>not proportional</u>

I need help please help me.
Nadusha1986 [10]

Answer:

20°.

Step-by-step explanation:

According to both the diagram and the presented angle measure, m∠RPS + m∠QPR = m∠QPS.

(4x + 27) + (9x - 115) = 107

4x + 9x + 27 - 115 = 107

13x - 88 = 107

13x = 195

x = 15

Now that we have the value of x, we can find the m∠QPR.

9x - 115

= 9 * 15 - 115

= 135 - 115

= 20

So, m∠QPR is 20°.

Hope this helps!

How old am I if 250 reduced by 5 times my age is 50?

250 - 5(x) = 50

250 (-250) - 5x = 50 (-250)

-5x = -200

-5x/-5 = -200/-5

x = 40

There are 250 students in the 6th grade 45% of the eat lunch in 4th period how many students eat lunch in 4th period?
horrorfan [7]

Answer: 112.5

Step-by-step explanation:

The question really is asking whats 45% of 250

1. Calculate 10% of the total

2. Calculate 5% of the total

3. Solve for 40% of the total

4. Add 5% of the total

1. 10% of 250

250 = 100%

*divide both sides by 10*

25 = 10%

2. 5% of 250

25 = 10%

*divide both sides by 2*

12.5 = 5%

3. 40% of 250

10% + 10% + 10% + 10% = 40%

25 + 25 + 25 + 25 = 40%

50 + 50 = 40%

100 = 40%

4. 45% of 250

100 = 40%

12.5 = 5%

100 + 12.5 = 40% + 5%

<em>112.5 = 45%</em>
