What is the measure of an angel that turns through 3/4 of a complete circle?
dimulka [17.4K]
2/3 think of this as a pie right divided into 3 area but only 2 people eat from it 1 left but how would i complete it if its not done well i need to  complete the "pie"
by adding an exponent into the mesure and cacultating a mass of a=mx+b
now you divide and get 0.75
so you will fill in .25 more to get the full measurement by eating 1 more pie:

Hook wants to set aside $2000 this year for a vacation. She plans on saving $48 dollars each week. There are 52 weeks in a year.
Doss [256]
I think it is reasonable. She will have extra cash (almost $500) but that isn't a bad thing when you are going on a vacation. 

If you need to know how to do it, what I did was take the $48 and the 52 weeks and multiply them together to get $2,496.... But if you think in your own opinion it's not reasonable than say she could trim down her savings and only try to earn about 40 dollars each week; you get to the closer amount of $2,000 with $2,080...

I hope this helps. Choose for yourself though! <3 Good luck! (:

F(1)=15<br> f(n)=f(n-1)*n<br> What does f(2) equal?
Arlecino [84]

Answer:

f(2) =30

f(1)=15

f(n)=f(n-1)*n

Put in n=2

f(2)=f(2-1)*2

If coal is mined at $35.99 per short ton, how much is the price per kg? Use dimensional analysis to solve. 1 short ton = 907 kg.
cricket20 [7]

The cost of 1kg of coal mined from the ore is $0.0397

Data;

  • 1 ton = $35.99
  • 1kg = ?

<h3>The Cost of 1kg of Coal</h3>

To find the cost of 1kg of coal, we can simply and equate 1 ton to its equivalent in ton and the solve.

1ton = 907kg\\

let's write this and equate it

1 ton = $35.99

907kg = $35.99

1kg = x

Let's cross multiply both sides and solve for x

907kg = \$35.99\\1kg = x\\x = \frac{1 * 35.99}{907} \\x = \$0.0397

The cost of 1kg of coal is $0.0397
