If P equals p plus at Find a when P equals 82 p equals 76 and t equals 20?
P = p + at 82 = 76 + a*20 6 = a*20 6/20 = a that is a = 3/10 or 0.3 That is the answer.
You do 45 J of work in 3 seconds How much power do you use?
p = 15 Explanation: p=w/t p= 45/3 p=15 watts
20 equals 4p plus 5 plus p?
20 = 4p + 5 +p 20 = 5p + 5 5p = 20 - 5 = 15 5p = 15 p = 15/5 = 3
A student opens a mathematics book to two facing pages. The product of the pages numbers is 420. Find the page numbers?
If one of the pages is numbered p, the other is p+1. So p*(p+1) = 420 That is, p2 + p - 420 = 0 which factorises as (p - 20)*(p + 21) = 0 That implies that p = 20 or p = -21. Assuming that pages do not have negative numbers, p = 20 and then the other page is p+1 = 21.

What is the 20 percent of 30.00?
6. all you have to do is use the IS over OF strategy. IS 20% and OF 30 so: P 20 30 100 then cross multiplication: P x 100 = 30 x 20 P x 100/100 = 600/100 P = 6 So there you have it, P = 6
20 equals 4p plus 5 plus p?
20 = 4p + 5 +p 20 = 5p + 5 5p = 20 - 5 = 15 5p = 15 p = 15/5 = 3
Petrol costs 81.9 p per liter how much does it cost if you travel 20 km if your car uses 0.25 liters every 10 km?
(20 km) x (0.25 litre/km) x (81.9 p/litre) = 409.5 p = ₤ 4.095
What is the future value of 10000 dollars with 3 percent interest after 20 years?
I'll do it both ways since you do not specify whether it is simple of compound interest. FV = P + PRT 10000 = P + P(.03)(20) 10000 = P(1 + 0.60) 10000 = 1.6P 6250 = P Check 6250 * .03 * 20 = 3750 + 6250 = 10000 ◄ FV = P + P(1+R)T 10000 = P + P(1.03)20 10000 = P + P(1.80611) 10000 = 2.80611*P 3563.65 = P Check 3563.25 + 3563.25(1.03)20 3563.25 + 3563.25*1.80611 3563.25 + 6436.35 9999.70 (Rounding error) ◄
What is the answer to 4p - 12 equals 20?
p = 8. The calculation for this equation works out as follows: 4p - 12 = 20 4p = 20 + 12 4p = 32 p = 32 / 4 p = 8
