As a retiring employee, you'll receive 5.96% of your average salary from the last five years you worked with your company.
You plan to retire after 37 years with the company.
Your salaries for your last five years are:
$180,267
$210,325
$126,591
$77,184
$173,175
Calculate your annual retirement salary.
Answer:
9,149.10
Step-by-step explanation:
To get the average you take all the values and add them up then divide by 5.
767,542 divided by 5 = 153,508.40
Now to get the percentage take 5.96 and divide by 100 = 0.0596
With this you can multiple the average by the percent in decimal form.
153,508.40 * 0.0596 = 9,149.10

Haley made 88% on a history test. The
test had 50 questions of equal point value.
How many questions did Haley miss?
Answer:
She missed 6 questions.
Step-by-step explanation:
88% can be written as (88/100) or as 0.88.
You can set this as a ratio problem which is,
88/100 = correct/50
correct = (88/100)*50 (multiply both sides by 50)
correct = 44
So, 50 (total questions) - 44 = 6 incorrect questions

K is between P and Q. Suppose PQ- 10x - 16, PK - 6x + 8, and KQ-8. What is PQ?
Answer:
PQ = 64
Step-by-step explanation:
PQ = PK + KQ
10x - 16 = 6x + 8 + 8
10x - 16 = 6x + 16
4x = 32
x = 8
PQ = 10(8) - 16
= 80 - 16

a negative times a negative is a positive and squaring those numbers would be multiplying a negative by itself.
For example (-2)*(-2) is 4
**note, this only applies if the negative value is in the parentheses. (-2)^2 is different than -2^2 because with -2^2 only the 2 is getting squared and then you’d have to multiply the negative after**

A bowling ball is placed on the moon.
Which feature of the bowling ball stays the same?
A. force from gravity
B. weight
C. mass
Answer:
C. mass
Step-by-step explanation:
gravity is different on the moon
and weight is different because of that change in gravity
If the bowling ball is placed on the moon, the feature which will stays same, mass of the ball. So option C is correct
What is Force ?The definition of force is the pushing or pulling of anything. Push and pull are the result of two things interacting with one another. Stretch and crush are two more phrases that can be used to describe force.
Given that,
A bowling ball is placed on the moon
So, when ball is placed on moon, it affects the following factors,
Force from gravity - On the Earth and on the Moon the gravitational force will be different.
Weight - On the Earth and On the Moon the gravitational acceleration will be different so weight will be different on both the planets.
Mass- It is the property of the object and it is independent from the planets, it will be same on every planet.
Hence, the Mass is same on both the planets

Find the length of the missing side. The triangle is not drawn to scale.

Answer:

Step-by-step explanation:
pythagorean theorem
take the sum of the square of each leg and set it equal to the square of the hypotenuse
8² + 6² = x²
64 + 36 = x²
x² = 100
x = [tex]\sqrt{100}[/tex] or 10
Answer:
B.10 units
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem which states that a^2+b^2=c^2
Plug in what we know....
8^2+6^2=c^2
64+36=c^2
c=sqrt(100)
c=10 units or B
The space probe Voyager I travels 3.255 x 108 miles in a year.
At this rate, how far does the Voyager I travel during a period of 40 years?
The Voyager I travel 130.2 x [tex]10^8[/tex] miles during a period of 40 years.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
The space probe Voyager I travels 3.255 x [tex]10^8[/tex] miles in a year.
So, in 40 years Voyager I travel
= 3.255 x [tex]10^8[/tex] x 40
= 130.2 x [tex]10^8[/tex] miles.
Thus, the Voyager I travel 130.2 x [tex]10^8[/tex] miles.
