(21 * 1.10) / 3 = 23.10/3 = 7.7....so each friend has to pay $ 7.70
Answer:
12 n 4−36 n 2+27 ... 12n4 - 36n2 + 27 = 3 • (4n4 - 12n2 + 9) ... splitting the middle term using the two factors found in step 2 above, -6 and -6
Step-by-step explanation:
hope this helps
Ok so you would take the number 6 and divide that by 1.50 since there are 6 plumes for 1.50. That is 25 cents per plum. But you want to buy 2 plums so multiply 25 by 2 which is 50 cents. Do the same for the apples,divide 3.00 by 5 which is 60 cents per apple but you want two apples so that is 1.20 for both apples. Then you have to figure out the cost of the plums and the apples so you add 50 cents to 1.20 and you get 1.70.
X = 7/12 or another way x= 0.583
Answer:
287
Step-by-step explanation:
The lateral surface area of a cone is r*pi*l, where l is the slant height. This is much like the formula of a square pyramid, which is a good way to understand this formula. But that aside, Lets plug in some values:
We know the diameter is 12 so r = 6.
Now lets find the slant height. We can draw a right triangle using the height, radius, and slant height. So we get, sqrt(6^2 + 14^2 ) = l, by Pythagorean's theorem. Therefore, l = sqrt(232) which is roughly 15.23
So we have 6*pi*15.23 which is roughly 287
