The formula for the volume of a pyramid is base*height*1/3
For this pyramid, it would be
(9*6)(10)(1/3)
540(1/3)
180
The answer is 180 cubic inches
If we're going to use an inequality to solve this, then we'd probably be saying that 3.25 x ? >210. The 3.25 is the selling price per taco and the ? is the number of tacos that you sell. According to the equation, the number of tacos times the selling price has to be greater than 210, which are the expenses, in order to gain a profit. If we solve this, we simply divide 210 by 3.25. We will get an answer of 65. So we can conclude that if the taco business wants to have a profit, then they have to sell more than 65 tacos so that they can be able to cover their expenses.
Answer:
(2a+3 ) (a-4 )=0
Step-by-step explanation:
2a^2 + 8a - 15 = 3a - 3
Subtract 3a from each side
2a^2 + 8a-3a - 15 = 3a-3a - 3
2a^2 + 5a - 15 = - 3
Add 3 to each side
2a^2 + 5a - 15+3 = 3 - 3
2a^2 -5a -12=0
(2a+3 ) (a-4 )=0 These are the factors
