Lets go ahead and calculate the area of each side; added together, this will give us the full surface area. First the base, which is 9 by 9 and a square. This means its area is 9*9, which equals 81. Next the triangles, which are all the same, so we only have to do it once and then add it 4 times at the end. The area of a triangle is (1/2)bh, so (1/2)(9)(7) = 31.5.
Finally, we just need to add the areas up.
81 + 31.5 + 31.5 + 31.5 + 31.5 = 81 + 4(31.5)
81 + 126 = 207 units^2
Answer:
y=mx+b where m is the slope and b is where the line crosses the y axis.
THe line crosses the y axis at 0, 2 so 2 = b
the slope is how many units the point goes up/down and to the left/right from the y intercept. From 0, 2 to 3, 3 the point goes up 1 and over to the right 3 times. rise/run is slope so 1/3 is the slope:
y=1/3x+2
Step-by-step explanation:
iiii wish iiiis corrrrrrect
The definition is pretty simple:
So, we only have to sum the expressions:
700 times 3 is 2,100, You get 700 from estimating 697
