<h3>
Answer: 40 cubic inches</h3>
=============================================================
Explanation:
This pyramid is strangely drawn, but 3D objects are hard to convey on a 2D surface sometimes. The shaded triangle represents the floor of the pyramid. This triangle has a base of 5 inches and height 6 inches.
area = base*height/2 = 5*6/2 = 30/2 = 15
The floor area is 15 square inches.
This is the value of the uppercase B in the formula V = (1/3)*B*h
The h is the height of the pyramid which is the 8 inch segment (not to be confused with the 6 inch segment)
So,
V = (1/3)*B*h
V = (1/3)*15*8
V = 5*8
V = 40 cubic inches
Answer:
25% is the same as 1/4. So to find 25% of a quantity, divide it by 4. First find 10% of it. Then find 1% of it, and use that 1% to find 2% of it.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given
f(x) = 3x - 40 and f(x) = 8 , then equate the right sides, that is
3x - 40 = 8 ( add 40 to both sides )
3x = 48 ( divide both sides by 3 )
x = 16 → C
Answer:
15 ft
Step-by-step explanation:
Using sinus law
sin(A) /a = sin(B) /b = sin(C) /c
Where smale letters indicate the sides
For this question :
(sin(90)*12)/sin(53)=15
It can go to 3.5/9 but thats as low as it can go
