C) they are parallel
as the slopes must be equal due to the fact they are both perpendicular to line n ( for a perpendicular line you flip the slope and change the sign , so both of them being perpendicular to n the slopes must be equal)
They cant interest at all since they are perpendicular and they may not be the same line
Answer:
A = 0.8 litres
B = 0.7 litres
C = 0.5 litres
D = 0.2 litres
Step-by-step explanation
Here's what we know:
1. Jug A = B + .1 litres
2. Jug C = B - 200 (or 0.2 litres)
3. Jug D = .25 x A
4. Jug A + Jug B = 1.5 litres
In problem 1, we learned that Jug A has .1 litres more than Jug B and in problem 4, the two of them added together are 1.5 litres. To solve this we can combine the problems.
B + .1 litres + B = 1.5 litres
2B + .1 = 1.5
Subtract .01 from each side and you have 2B = 1.4
Divide each side by 2 and you have B = 0.7 litres
Plug this info into problem 1 and you can solve for A. (0.7 + 0.1 = 0.8)
Plug this info into problem 2 and you can solve for C. (0.7 - 0.2 = 0.5)
Since you have A, you can use that info to solve problem 3 (0.25 x 0.8 = 0.2)
Answer:
x^3-6x^2-10x+100
Step-by-step explanation:
Step 1: Distribute x to (x²-6x+20).
x(x²-6x+20)=x^3-6x^2+20x
Step 2: Distribute 5 to (x²-6x+20).
5(x² − 6x + 20)=5x²-30x+100
Step 3: Combine x^3-6x^2+20x and 5x²-30x+100.
x^3-6x^2-10x+100
hope it helps you <3
divide the two:
52.50 / 7 = 7.50 per hour
