Draw a right rectangular prism. Draw it so one face is pretty much the way you would see it if it was real. The other two faces you can see have a slant to them.
Label the face you can see as x and y. Name any of the slanted lines as z. Put cm for centimeters behind the letters.
Volume = x*y*z the units here are cm^3
Why because you are multiplying cm*cm*cm together.
The surface area is a whole different ball game.
you have 2 surfaces who have areas of x*y There's one in front of you and one you cannot see
You have a top and a bottom that is y*z each that's 2y*z
You have two surfaces that are x*z each and that's 2x*z
The total surface area = 2xy + 2xz + 2yz
The units here are cm*cm or cm^2
Window size goes from -10 to 10 on both axes
To find this out:
Turn the percent into a fraction and cross multiply!
5%=5/100
5 39
_ × ____
100
Multiply 39 × 100 (3,900)
Then divide by 5!
3900/5=780
39 is 5% of 780!
Answer:
F. 82
Step-by-step explanation:
To calculate the length of BC, Pythagoras theorem will be used.
It says, Hypotenuse^2 = Perpendicular^2 + Base^2
In our case, Perpendicular = AB = 18 and Base = AC = 80
therefore,
Hypotenuse^2 = 18^2 + 80^2 = 6724
Hypotenuse = BC = 
= 82
The answer could be 32^(-2)
