Answer:
If the prism is trapezoid then you need to find the height and use this formula
1/2 x a+b x h
This has been done below you only need to fill in the height and do the shape for 3cm x 2cm as you haven't been clear in your question.
Volume = 8 x h x 10 = 80 x h cm^3
Hope this helps.
Step-by-step explanation:
Slope triangle prism and or rectangle
The area can be seen either by finding height of the triangle or working out the rectangle and halving the rectangle.
Step-by-step explanation:
Volume
6 x 8 = 48cm^2
48 x 5 = 230cm^2 for double (rectangle prism of 6 x8)
385/2 = 115cm^2 triangle slope prism
---------------
Area first
trapezoid front measures 6,5, 10
1/2 x 6 + 5 x h
=1/2 x 6 + 5 x h
= 8 x h x 10= 80 x h
Volume = 8 x h x 10 = 80 x h cm^3
Answer:
21/2
Step-by-step explanation:
10*2+1/2=21/2
use the formula
a
=
Answer:
y = 6
Step-by-step explanation:
7x - 9y = 23
7(11) - 9y = 23
77 - 9y = 23 (subtract 77 from both sides)
-9y = -54 (divide both sides by -9)
y = 6
Answer:
wearing to not wearing= 7:5
5x=30
x=6
7(6)= 42
Answer is 42
Step-by-step explanation:
Don’t trip just use the distributive property. -5(3x-2)= -50 which would end up being -15x -7 = -50; then add 7 to both -7 which then they will cancel out and add 7 to -50 which equal -43 so x = -43
