on a recent survey, 90% of those surveyed indicated they preferred walking to running. If 130 people preferred running to walkin
maks197457 [2]

Answer:

<u>145 people were surveyed</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Percentage that indicated they preferred walking to running = 90%

2.  If 130 people preferred running to walking, how many people where surveyed?

For answering this question, we will use the Rule of Three simple, this way:

x = Number of people surveyed

90 * x = 130 * 100

90x = 13,000

x = 13,000/90

x = 144.44

But we need a whole number for an accurate answer, so we round the value of x to the next whole number.

<u>145 people were surveyed</u>

Please help I can’t solve this

1.25

If you take the difference between two y axis numbers (say 5 and 10) which is 5 and the difference between two X axis numbers (say 4 and 8) which is 4. The y axis is the rise(5) and the x axis is the run(4). Using the formula rise/run (5/4) you can calculate the answer to be 1.25.

Are these ratios equivalent?
Debora [2.8K]
<h3>Answer:  Yes</h3>

========================================================

Explanation

The ratio 8:10 simplifies to 4:5 when you divide both parts by 2.

The ratio 16:20 simplifies to 4:5 when you divide both parts by 4

Therefore the two ratios 8:10 and 16:20 are both equal 4:5, so they are equal to one another.

------------

Put another way,

(8 large)/(10 small) = (16 large)/(20 small)

8/10 = 16/20

8*20 = 10*16 ... cross multiply

160 = 160

We get a true equation, so the first equation is true as well.

This shows the ratios are equivalent.

-------------

Or you could have...

(8 large)/(16 large) = (10 small)/(20 small)

8/16 = 10/20

8*20 = 16*10

160 = 160

We get the same conclusion as before.
