How do you write a ratio as a percent

1 answer:

3 0

Let's use the ratio 3:6 as an example. So 3:6 is the same as 3 over 6, aka 3/6. Divide 3 by 6 and you'd get 0.50. To turn a decimal into a percent, move the decimal to the left 2 times. (If you want to turn a percent into a decimal, you'd move the decimal to the right 2 times.) So then, 0.50 becomes 50%. Hope I helped!!! :-) (You could also multiply the decimal by 100 if you find that quicker/easier)

What is the predicted difference in sleep between individuals A and B, where individual A has 12 years of education and works 20

kari74 [83]

Answer: The predicted difference in sleep is 1251437 minutes.

Step-by-step explanation:

Since we have given that

Number of years of education = 12 years

Number of minutes a week = 2000

As we have

In case of individual A:

7 days = 2000 minutes

1 year = 365 days = $\dfrac{2000}{7}\times 365=104285$

12 years = $104285\times 12=1251420\ minutes$

In case of individual B:

7 days = 3000 minutes

1 year = 365 days = $\dfrac{3000}{7}\times 365=156428$

16 years = $156428\times 16=2502857$ minutes

So, the predicted difference in sleep between individuals A and B is given by

$2502857-1251420\\\\=1251437\ minutes$

Hence, the predicted difference in sleep is 1251437 minutes.

Step-by-step explanation:

From the scenario described :

The length of the rope, h is the hypotenus. From the data Given, we cannot obtain how far wthe bird will need to fly directly, we use Pythagoras rule to calculate the hypotenus of the triangle :

Hypotenus, h = sqrt(opposite² + adjacent²)

h = sqrt(7² + 5²)

h = sqrt(49 + 25)

h = sqrt(74)

h = 8.6 feet
