Answer:
684 sq.ft
Step-by-step explanation:
(1) The base area of the pyramid is 18x20=360 sq.ft
(2) The Triangles of the pyramid:
1. There are two kinds of the triangles.
2. Smaller one: 18x8/2 (base times height divide 2)=72 sq.ft
3. Bigger one: 20x9/2=90 sq.ft
4. There are two of them so 72+72+90+90=324 sq.ft
And so 360+324=684 sq.ft.
Answer: y=(x-1)/2
Step-by-step explanation:
To find the inverse, you want to switch the y with x and x with y. Then, you solve.
y=2x+1 [switch y with x and x with y]
x=2y+1 [subtract both sides by 1]
x-1=2y [divide both sides by 2]
(x-1)/2=y
Now, we know that y=(x-1)/2 is the inverse.
It would be 110 miles. 5×20=100 and half of 20 is 10
