The volume for a pyramid is
, where B is the area of the base and h is the height. We are given the volume, and the base and height in terms of x. Our formula then looks like this:
. Simplifying the right side we have
. Multiply both sides by 18 to get rid of the fraction and we have
, so x = 117.575
Answer:
19600
Step-by-step explanation:
For every year the profit increases by 40% so to figure out the profit from 2017 to 2018 you do 10,000*1.4 to and get 14,000. To get 2019's profit you do the same process, but use 2018's profit of 14,000 instead of 2017's profit to get 19,600.
The measurements are 3 times as big.

Answer:
Area of the figure = 350 cm²
Step-by-step explanation:
Area of the given figure in the picture = Area of big rectangle - Area of small rectangle A
Area of big rectangle = Length × Width
= 25 × 15
= 375 cm²
Length of mall rectangle = 25 - (5 + 15)
= 5 cm
Width of small rectangle = 5 cm
Area of small rectangle = 5 × 5
= 25 cm²
Area of the figure = 375 - 25
= 350 cm²
