Last year, 9 employees of an electronics company retired. Their ages at retirement are listed below.

51 61 62
54 68 58
60 57 54

Find the mean retirement age.
58.3 yr
57.7 yr
58.0 yr
57.1 yr

Answer:

A

Step-by-step explanation:

Answer:

C. 35 sq. units

Step-by-step explanation:

in order to find the area of a triangle you have to use the formula

1/2 b h

b as in base

h as in height

so if we use the measurements on the triangle and we plug that in we will get

1/2 x 14 (the base) x 5 (the height)

therefore giving us 35 sq. units.

hope this helps!

Hey could U help me with this question

Answer:

3.45

Step-by-step explanation:

if 4 pints are 13.80 you would have to divided 13.80 by 4 and 4 by 4 to get 1 over blank. The denominator would be 3.45 which would be the amount 1 pint cost. If you don't want to do it as fractions you can simply divide 13.80 by 4.

Answer:

No solutions; parallel

Step-by-step explanation:

The equations x=16 and x=3 both have a slope of 0. So when graphed, they would be parallel and there are no solutions between parallel lines.

Answer:

a = 86y

Step-by-step explanation:

Given:

Number of applicants per year = 86

Find:

Equation represent total applicants

Computation:

Assume;

Total number of years = y

Total number of applicants = a

So,

Total number of applicants = Number of applicants per year x Total number of years

a = 86 x y

a = 86y

Step-by-step explanation:

Answer:

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6, and the correct answer 6, 8, and 10.

Step-by-step explanation:

Jared wanted three consecutive even integers, whose sum is 4 times the first integer.

He let k represent the first integer and wrote:

[tex]k+(k+1)+(k+2)=4k[/tex]

We can solve this first. Combine like terms:

[tex]3k+3=4k[/tex]

So:

[tex]k=3[/tex]

This means that our sequence will be 3, 4, and 5, which is not correct since we have odd integers.

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation*:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6**, and the correct answer 6, 8 , and 10.

To verify, 6 + 8 + 10 = 24.

And 6(4) = 24, so our answer is correct.

**To solve, we can combine like terms:

[tex]3k+6=4k[/tex]

So:

[tex]k=6[/tex]

*The reason we use (k + 2) instead of (k + 1) is because (if k is an even number), then adding 2 guarantees another even number. If we added only 1, we will get odd numbers.

Step-by-step explanation:

Step-by-step explanation:

[tex] \tt{30.16 = 17.56 + 5x} [/tex]

Swap the sides of the equation :

⤑ [tex] \tt{17.56 + 5x = 30.16}[/tex]

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ [tex] \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}[/tex]

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ [tex] \tt{5x = 12.6}[/tex]

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ [tex] \tt{ \frac{5x}{5} = \frac{12.6}{5}} [/tex]

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

[tex] \pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}[/tex]

Hope I helped ! ♡

Answer:

100

Step-by-step explanation:

"Percent" or "%" means "out of 100" or "per 100".

Therefore 20% can be written as  20 /100

Therefore, 20 is 20% of  100

Answer: 1/14, 2/28.

Step-by-step explanation:

2/7 x 0.25 =

Convert 0.25 into a fraction.

0.25 = 1/4.

Multiply the numerators together and then multiply the denominators with each other.

1/4 x 2/7 = 2/28.

Therefore, the answer is 2/28, but it can also be simplified to 1/14. So the answer is the first one, or 1/14.

Answer:

1/14 or A

Step-by-step explanation:

0.25 as a fraction is 1/4

1/4 x 2/7 = 2/28, simplify to become 1/14, and there is your answer

Answer:

-10

Step-by-step explanation:

we know that when x=4 y=2 so we can just plug in the numbers

2=3(4)+b

-10=b

Divide the number by your guess. Now you have two numbers that multiply to get your original number. Take the average of these two numbers. This becomes your second guess for the square root.

Answer:

you can find it with do its LCM.

Answer:

x = - 8/23

y = 40/23

Step-by-step explanation:

-5x- y = 0

and

-8x+3y = 8

The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.

-5x-y = 0

-y = 5x

y = - 5x

Now you can take this y value and plug it into the section equation.

-8x + 3(-5x) = 8

-8x - 15x = 8

-23x = 8

x = - (8/23)

Once you get the x value you can plug it back into equation one to get y's value

-5*-(8/23)  - y = 0

40/23 - y = 0

y = 40/23
