there are four Defenders on a soccer team that this represents 20% of the players on the team which equation can be used to find the total players on the team plzz help me like this is hard

Answers

4=(total players on the team) x 0.2
(total players on the team) = 4/0.2
(total players on the team) = 20

20% is the same as 0.2.
2 is 20% of 10.
to find 10, divide 2 by 0.2
2/0.2=10
4 is 20% of something
to find 'something', divide 4 by 0.2
4/0.2=20

Brian wants to buy a motorcycle and is planning to get motorcycle insurance. Suppose the average accident rate is 0.1, and the average expenses incurred on accidents is $38,000. The insurance plan has a yearly premium of $1,000 and a deductible of $4,000.If after 4 years of insuring 100 people, 9 motorcycle drivers had an accident, where does the company stand after money has been taken in and paid out for this group of 100 insured people?

$85,500
-$36,000
$94,000
$58,000

Answers

Answer:

The correct option is $94,000

Step-by-step explanation:

Yearly premium under the insurance plan = $1,000

Total premium from single motorcycle driver in 4 years = $1,000 * 4 = $4,000

Number of people insured = 100

Total premium collected from 100 motorcycle drivers = $4,000 * 100 = $400,000

Average expenses incurred on accident = $38,000

Deductible = $4,000

Net expenses incurred per accident = $38,000 - $4,000 = $34,000

In 4 years , 9 motorcycle drivers had an accident

Total expenses incurred for accident = $34,000 * 9 = $306,000

Net savings of Insurance Company = total premium - total expenses = $400,000 - $306,000 = $94,000

Hope it helps.

Thank you !!

It's $94,000

1,000 X 100 X 4 = 400,000

If y = kx, what is the value of k if y = 20 and x = 0.4?

Answers

y = kx
20 = .4k
--- ----
.4 .4

50 = k

First when two variable are next to each other it means to multiply.
In this problem you have to do inverse operations.
20÷0.4=50
So the answer is 50.
