Answer:
The area would be 170 cubic inches.
Step-by-step explanation:
To find the area, use the area of a trapezoid formula.
A = (a + b)/2*h
Now input the values
A = (18 + 22)/2 * 8.5
A = 40/2 * 8.5
A = 20 * 8.5
A = 170
8/2 = 4
Explanation : reverse it so 4 times 4 = 8
10 years divided by 5 years is 2 years(thats how many times u double) then double 450 once =900 then double it again=1800
so the answer would bw $1,800
Answer:
36.56
Step-by-step explanation:
it's actually a rectangle and a circle
the per. of the rectangle is 8 x 2 + 4 x 2 = 24
the per. of the circle is 2.r.pi, 2.2.3.14 = 12.56
.
24+12.56 = 36.56
Answer:
f(h) = (5h² + 3h) / 2
f(6) = 99 cm²
Step-by-step explanation:
Let's call this function f(h), as we are referring to the base of a triangle in terms of its height.
The equation for the area of a triangle is given by
A = (base * height) / 2
Let's denote height as h and base as b
base b = 5h + 3
Let's substitute base b in terms of h for our area equation
A = ((5h + 3) * h) /2
Expanding this
A = (5h² + 3h) / 2
Written as a function of height then we have
f(h) = (5h² + 3h) / 2
Let's solve for the area of a triangle then who's height is 6 cm
f(6) = (5(6)² + 3(6)) / 2
f(6) = (180 + 18) / 2
f(6) = 198 / 2
f(6) = 99 cm²
