Answer:
Step-by-step explanation:That is, the circumference would be the length of the circle The area of a circle is pi (approximately 3.14) times the radius of the circle squared. The circumference is pi times the diameter if it were opened up and straightened out to a line segment.
Alright first off 8 filters cost $39.92 and out goal is to find the cost of 6 filters Set this up as a proportion. 8 = $39.926 = x
So let find x
x = (6)($39.92) / 8 = $29.94 <span>It costs $29.94 to buy 6 filters.</span>
Step-by-step explanation:
- m <a+m <b+m <c=180 {sum of angles in a straight line are 180}
- 3x+5+5x-18+7x-2=180
- 15x-15=180
- 15x=180-15
- 15x=165
- x=165/15
- x=11
- so, m<a=3x+5=3×11+5=33+5=38
m<b=5x-18=5×11-18=55-18=37
m <c=7x-2=7×11-2=77-2=75
part B: no bcuz their sum isn't 90 whereas to be complement it must be 90
Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
× 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches
