Answer:
5"
Step-by-step explanation:
Set this up as a proportion: 3 is your constant of proportionality
3 / 5
9 / 15
3/5 x 3/3 = 9/15
To calculate the x-intercept of a line written in standard form you simply remove the "y" and solve for x. And you remove the "x" when solving for y.
y=0 , solve for x
x=0 , solve for y
Here is an example: (solving for x)
2x + 3y = 6
2x + 3(0) = 6
2x = 6
2x/2 = 6/2
x = 3
Here is an example: (solving for y)
2x + 3y = 6
2(0) + 3y = 6
3y = 6
3y/3 = 6/3
y = 2
Since it is about only the outer part of the aquarium which is made of glasses we need to calculate the total surface area.
Surface area of the base = 4*3 = 12 square feet
Surface area of the shorter length of wall = 3*2 = 6 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
6*2 = 12 square feet
Surface area of the longer length of wall = 4*2 = 8 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
8*2 = 16 square feet
Therefore the total surface area that need to be covered with glasses
12+12+16 = 40 square feet
A square is a parallelogram, a rectangle, and a rhombus,
but it is not a pentagon.
Answer:
Step-by-step explanation:
(8-5)/(1-0) = 3/1 = 3
y - 5 = 3(x -0)
y -5 = 3x - 0
y = 3x + 5
