Answer:
40 percent
Step-by-step explanation:
Start by taking the difference of the two values:
35-25 = 10.
the $10 is how much the value increased by.
To get the percent that the $25 increased by, take 10/25 to get .4
This .4 can then be turned into a percentage when you multiply it by 100. = 40 percent.
You can check your answer by finding 40 percent of 25, which is 10.
Answer:
204 in^3
Step-by-step explanation:
The volume of the base square is V=lwh.
When we substitute our givens, it becomes V=6(4)(2). This equals 48 in^3.
The volume of the triangle is V=.5lwh.
When we substitute our givens, it becomes V=.5(6)(4)(15-2). This equals 156 in^3.
When we add 48 and 156, we get 204 in^3.
Hope this helps :)
