Sarah has private health insurance that costs $575 per month. Her new employer will provide health insurance at no cost to her. What is her health insurance worth as a benefit of employment?

Answers

Based on the above information, it can be inferred that Sarah saves $6,900 per year.

How to calculate how much Sarah saves per year in health service?

Taking into account that her new employer is going to give her a free health service and that before she paid $575 for the health service monthly, to calculate her savings per year we must multiply the value of the health service by the number of months of one year (12).

$575 × 12 = $6,900

Based on the above, it can be inferred that Sarah is saving $6,900 per year on health care.

On Thursday afternoon at camp, Nora played basketball and went swimming before dinner. She started playing basketball at 2:50 P.M. and played for 1 hour and 45 minutes. Then she swam for 50 minutes. Dinner lasted for 1 hour. What time did dinner end?

Answers

Answer:

6:25 PM

Step-by-step explanation:

Start of dinner

2:50 PM + 1:45 + 0:50

convert it to minutes

2:50PM + 60+ 45 + 50

= 2:50Pm + 60 + (50 + 10) + (45 - 10)

= 4:50Pm + 35

= 4:50PM + 10 + 25

= 5:25PM

Which words mean the same thing as 5/8

Answers

Answer:

c) Five out of 8 equal parts of a whole

Step-by-step explanation:

The statement "Five out of 8 equal parts of a whole" means the fraction of 5/8. Hence, option (c) is the correct answer.

Answer:

"Five out of eight equal parts of a whole"

Step-by-step explanation:

In a fraction, the numerator (top part) is saying "this number out of the number below it."

The denominator (lower part) is the number below it that we are taking the proportion out of.

A denominator is ALWAYS equal parts, so if we match up the phrase: "5 out of eight equal parts of a whole"

In a town, 15% of the population is unemployed. what is the
total population, if number of people who are employed is
8381

Answers

Answer:

1479 people

Step-by-step explanation:

If the amount employed is 8381, that means 8381 is 85% of the population. 8381/85 = 98.6

Every 1% of the population is 98.6, so we can just do 15 x 98.6 to get 1479

Answer:

9,860

Step-by-step explanation:

100% - 15% = 85 % = 85/100

85/100 * 8381/x

85x = 838,100

838,100/85 = 9,860

15 men produce 500 watches in 15 working days. How long would it take 45 men to produce 500
watches?

Answers

Answer:

It would take 45 men 5 days to make 500 watches.

Explanation.

for 15 men it takes 15 days.

but if you have 45 men. that is 3x the amount of men.

they will be able to make watches 3 times faster.

just believe me its the right answer.

Please Vote Me Brainliest. Thank You.

(Assuming every single man has the same working rate.)

Solution 1 :

If there is 45 men working, there will be 45 : 15 = 3 times as much men.

So, the amount of time taken will be reduced by 3 times.
=> It will take 15 : 3 = 5 days for 45 men to produce 500 watches.

Solution 2 :

15 men produce 500 watches in 15 days -> If there is only 1 man, it will take 15 x 15 = 225 (days).

If there is 45 men, the amount of time will reduce by 45 times.

So, it will take 225 : 45 = 5 days for 45 men to produce 500 watches.

write y=x^2+24x+124 in vertex form. step by step

Answers

Step-by-step explanation:

the general vertex form is

y = a(x - h)² + k

with (h, k) being the vertex of the curve.

after doing all the multiplications we get

y = a(x² - 2hx + h²) + k = ax² - 2ahx + ah² + k

now we have

y = x² + 24x + 124

and we can compare

ax² = x²

a = 1

-2ahx = -2hx = 24x

-2h = 24

h = 24/-2 = -12

ah² + k = 124

(-12)² + k = 124

144 + k = 124

k = -20

so, the vertex form is

y = (x + 12)² - 20
