Volume = 12 * area of triangular base
area of triangle = 1/2 base * height = 3 * height
height = sqrt(5^2 - 3^2) = 4
area of triangle = 4*3 = 12
Vol of prism = 12*12 = 144 cubic units
(0.7p)=p-250
30% off of p must be equal to 250 less than p. As a result you can say that 0.7p (0.7Xp), which is 70% of p (100%-30%=70%) is equal to p-250, so 0.7p=p-250.
Tina takes Karate classes every Tuesday and Thursday. The classes are 55 minutes long.
Take the 55 minutes and multiply that by 2 {2 represent Tuesday and Thurdsday} 55 x 2 = 110. Tina takes Karate classes for 110 minutes each week. Take the 110 and multiply that by 3 {3 represent the 3 weeks}. 110 x 3 = 330. 330 minutes is 5 hours and 30 minutes.
Tina's total hours of Karate in 3 weeks is 5 hours and 30 minutes.
