Answer:
D
Step-by-step explanation:
the lines will be parallel if when cut by a transversal line form same size angles, so 63= x-1, therefore x = 64°
Answer:
15 (x+y)
Step-by-step explanation:
Multiply 6 with inside the parenthesis 6(2x+3y) ➡ 12x + 18y
Multiply 3 with inside the parenthesis 3(x-y) ➡ 3x - 3y
Now add them up
12x + 18y + 3x - 3y = 15x + 15y ➡ 15(x + y)
It will take 4.7 minutes to empty the tank. This is because you first would have to find the area of the tank. In order to do that you would have to find the area of just the flat circle, so to do that you do the radius squared times pi. So take the diameter divide it by 2 And get 0.8 (radius) and then square it (multiply it by itself) and get 0.64 than multiply it by 3.14. Than take the answer to that and multiply it by the height (4) and than divide by 1.7 .
Hope that helped :)
