Answer:
2 1/4
Step-by-step explanation:
In an equilateral triangle, all 3 sides are the same length. If one side length is x, the perimeter is x+x+x or 3x which is equal to 6 3/4 as said in the problem. You get the equation 3x=6 3/4. Dividing both sides by 3, you get x=2 1/4.
Answer:
<u>Each of the 4 sectors have an area:</u>
- πR²/8 - πr²/8, where
- R = 28/2 - 2 = 12 in
- r = 6/2 = 3 in
<u>Find the area:</u>
- A = π/8(12² - 3² ≈ 53 in²
<u>Outer perimeter of the frame:</u>
- P = d + πd/2 =28( 1 + π/2) ≈ 72 in
Answer:
x=2
Step-by-step explanation:
Answer:
(- 1, 5 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(- 1, - 5 ) → (- 1, 5 )
I believe its 80 if you derive it out, but there is no units of measurement.
