In a town, 15% of the population is unemployed. what is the
total population, if number of people who are employed is
8381
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
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?
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 = $6,900Based on the above, it can be inferred that Sarah is saving $6,900 per year on health care.

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

Which words mean the same thing as 5/8
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"
2. If ¡2x+3 = i, where i = V-1, then which of the
following is a solution for x?
(1) x = 16
(3) x = 11
(2) x = 10
(4) x = 14
I assume you mean the equation
[tex]i^{2x+3} = i[/tex]
Since i = √(-1), we have i⁴ = 1 and so i⁵ = i. Then 2x + 3 must be some multiple of 5.
Now just check for which of the given choices that this holds:
x = 16 ⇒ 2x + 3 = 35 (yes)
x = 11 ⇒ 2x + 3 = 25 (yes)
x = 10 ⇒ 2x + 3 = 23 (no)
x = 14 ⇒ 2x + 3 = 31 (no)

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)

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.

The lines that appear tangent are tangent. What is the value of x, to the nearest tenth.
Answer:
x ≈ 10.7
Step-by-step explanation:
Is given in the picture that x is the radius of the circle.
The radius of a circle and the tangent line to the circle form a right angle, therefore our triangle is a right triangle.
We can apply the Pythagorean Theorem to find one equation that will have one unknown x.
(x+12)² = x² +20² , use that (a+b)² = a²+b²+2ab
x²+12²+2·x·12 = x² +20², subtract x² from both sides of the equation
12² + 24x = 20², subtract 12² from both sides of the equation
24x = 20²-12², raise to power and combine like terms
24x = 256, divide by 24 both sides of the equation
x = 10.6666666..., round to the nearest tenth
