Answer:
-7.35
Step-by-step explanation:
7/x = cos(60)
x = 7(cos(60))
x = 7/(-0.95)
x = -7.35
There is a 57% they will both be black.
8+6=14
8÷14=.571 move decimal point 2 to the right
Might be 134 because since angle 2 and 8 are lined up like that it is same side exterior angles which means they are supplementary from each other so they will equal 180. So I did 180-46 to get 134, I’m not sure if I’m correct
Considering the volume of a rectangular prism, the capacity of the second sandbox would be of 80 cubic feet.
<h3>What is the volume of a rectangular prism?</h3>
The volume of a rectangular prism with length l, width w and height h is given by the multiplication of the measures, that is:
V = lwh.
In this problem, the capacity is of 10 cubic feet, that is:
V = lwh = 10.
When each measure is doubled, the volume will be given as follows:
V= 2l x 2w x 2h = (2 x 2 x 2)lwh = 8lwh = 8V = 80 cubic feet.

Answer: (0, 1), (-1, -3)
Given two equation's:
- y = 2x² + 6x + 1
- y = −4x² + 1
<u>Solve them simultaneously</u>:
(a) When x = 0, y = −4(0)² + 1 = 1
(b) When x = -1, y = -4(-1)² + 1 = -3
Solution: (x, y) → (0, 1), (-1, -3)
