Answer:
Paint required will be 2.06gallons
Step-by-step explanation:
The given dimensions are
Height - 8ft
Width - 7
= 7.9ft
Length - 9. 83ft
To calculate the the amount of paint required to paint the walls we need to find the area of the walls
wall 1 = height * width of room= 8 * 7.9 = 63.28![ft^2](https://tex.z-dn.net/?f=ft%5E2)
wall 2 = height * length = 8*9.83 = 78.64 ![ft^2](https://tex.z-dn.net/?f=ft%5E2)
The total area of the 4 walls will be = 2*(63 .28+78.64)= 283.84![ft^2](https://tex.z-dn.net/?f=ft%5E2)
ceiling area = 77.66![ft^2](https://tex.z-dn.net/?f=ft%5E2)
total area to be painted = 283.84 + 77.66 = 361.50
One gallon of paint covers 350
of area
so 361.50
area will be covered by = 361.5/350 = 1.03gallons of paint
also we need two coating so the paint required will be = 1.03 * 2 =2.06gallons
Answer:
Option 1
Step-by-step explanation:
Counter-intuitively, the correct answer is option 1. Option 2 is obviously a cross section, since it is the shape of the base of the triangle. Option 3 is also obviously a cross section, since the figure is a triangular prism. Option 4 is a cross section because, if you slice diagonally, you may create a cross section with a wider base on the bottom and larger on top. However, it is impossible to create a cross section of a rectangle from this square pyramid. Hope this helps!
First subtract 30 from both sides so it is equal to 0
the quadratic formula is -b plus or minus sqrt of (b^2 - 4ac) all over 2a so
-10 plus or minus sqrt (100-25) all over 2
this is equivalent to
A polynomial in standard form only means that you put it in order of descending x values. Multiplying out those 2 factors gives us
. Combining like terms and we have
. That's in standard form.
The answer would be a meter.
