An art teacher has a total of 5/8 pound of clay.The teacher puts 1/32 pound of clay at each work station.How many total work station will the art teacher be able to set up

Answers

Answer: Total work stations = 20

Step-by-step explanation:

Total clay = [tex]\dfrac58[/tex] pound

Clay at each work station = [tex]\dfrac1{32}[/tex] pound

Total work stations = (Total clay ) ÷ (Clay at each work station )

[tex]=\dfrac58\div\dfrac{1}{32}\\\\=\dfrac58\times32\\\\= 5\times4\\\\= 20[/tex]

Hence, Total work stations = 20

Step-by-step explanation:

Angela works 18 hours a week for 12 weeks in the summer at the local swimming pool as a life guard. She earns $13 per hour. Her employer takes 15 percent out of her check for federal income tax withholding and 6.2 percent for Social Security and 1.45 percent for Medicare. She will receive 12 paychecks, one for each week she works. Calculate Angela’s weekly gross pay

Answers

Answer:

We know that per week, she works 18 hours.

For each of these hours, she earns $13.

Then in one week, she earns a total of:

18*$13 = $234

This is her gross pay (the pay before the taxes apply)

Now we know that her employer takes:

15% for federal income tax withholding.

6.2% for Social Security

1.45% for Medicare.

If we add all of these, we get:

15% + 6.2% + 1.45% = 22.65%

This means that 22.65% of $234, is taken by her employer to pay taxes and such.

Then the amount left is:

M = $234 - ( 22.65%/100%)*$234 = $234 - 0.2265*$234 = $180.999

And we can round the last digit to $181 (because we can not have a 0.009 of a cent)

This means that her weekly net pay is $181

And she works for 12 weeks, this means that in total, she will earn:

12*$181 = $2,172

Answer:

growth2.3%

Step-by-step explanation:

The number with the exponent is 1+0.023/4 = 1.00575. This number is greater than 1, so represents growth.

When x increases by 1, the multiplier of 800 increases by ...

1.00575^4 ≈ 1.023199 = 1 + 2.3199%

Rounded to the nearest tenth percent, this is a 2.3% growth rate.

_____

Additional comment

The formula corresponds to a financial formula in which a 2.3% annual interest rate is compounded 4 times per year. The effective annual interest rate is almost 2.32% per year. The difference is there, but is too small to see when the interest rate is rounded to a tenth percent.

A robin can fly 10 miles per hour faster than a blue jay. It takes a robin 1 1/2 hours to fly 45 miles.

How many hours will it take a blue jay to fly that same distance?

Answers

Answer: [tex]2\dfrac14\text{ hours}[/tex]

Step-by-step explanation:

Given: It takes a robin [tex]1\dfrac12[/tex] hours to fly 45 miles.

[tex]1\dfrac12=\dfrac32[/tex]

Speed of robin= [tex]\dfrac{distance}{time}=\dfrac{45}{\dfrac32}[/tex]

[tex]\dfrac{45}{3}\times2= 15\times2= 30\text{ miles per hour}[/tex]

A robin can fly 10 miles per hour faster than a blue jay. It

Speed of Blue jay = Speed of robin - 10 miles per hour

= 30 miles per hour - 10 miles per hour

= 20 miles per hour

Time taken to cover 45 miles = [tex]\dfrac{45}{20}=\dfrac{9}{4}=2\dfrac14\text{ hours}[/tex]

Hence, it will take [tex]2\dfrac14\text{ hours}[/tex] by a blue jay to fly that same distance.
