Answer:
Step-by-step explanation:
Complement means the other angle that will sum up to 90°
So:
x + 2x = 90°
3x = 90
x = 30°
So, it is 30° and 30 * 2°, or 60°
If you type the equation into y1 on your calculator and use the table graph you get coordinates that you can graph. ( 0,-9 ) ( 1,-6 ) ( 2, -3 ) ( 3 , 0 ) ( 4, 3 ) ( 5 , 6 ) ( 6 , 9 ), just graph those and that should answer your question :)
3 1/2 x 1/4= 7/2 x 1/4= 7/8 so he's watered and fertilized 7/8 of an acre today.
Answer:
10 inches by 4 inches
Step-by-step explanation:
Area of envelope, A = 40 in²
Perimeter of envelope, P = 28 in
Area = Length * width, L*W
Perimeter = 2(L + W)
40 = LW - - - (1)
28 = 2(L+W)
28/2 = L+W
14 = L+W - - - (2)
Solving like a quadratic equation ;
We need two numbers whose sum gives 14 and product gives 40
The numbers are 10 and 4
(10*4) = 40 and (10+4) = 14
