Answer:
8 l
Step-by-step explanation:
1 l = 1000 mm
8000 mm = 8000/1000
8000 mm = 8 l
Answer:
1 hour 12 minutes or 1.2 hours
Step-by-step explanation:
You add fractions to get this.
1 room/3 hours + 1 room / 2 hours = 1 room / x
0.33333333+0.5 = 1 room / x
0.83333333 = 1 / x Multiply both sides by x
0.83333333x = 1 Divide by 0.8333333
x = 1/0.833333
x = 1.2 hours or
x = 1 hour and 12 minutes
Answer:
60 cubic inches
Step-by-step explanation:
A = πr²(h/3) = 4(5)π
Answer:
(for the second one)
y = 4x + 10
solution:
so first you have to find the slope, there is an equation for it. it is y2 - y1/ x2 - x1 or just y1 - y2/ x1 - x2 . so input the easiest points. id say f(0) and f(1)
so it will look like
2 - 6/0 - 1
-4/-1
4
so you can now write the equation as
y = 4x + b
now you have to find the y-intercept so input a point. i dont think you should input a point you used to find the slope because you could have made a mistake calculating so lets input f(2)
sooo
18 = 4(2) + b
18 = 8 + b
b = 10
so the function for the second one is y = 4x + 10
Answer:
11x+5=13x=5
We move all terms to the left:
11x+5-(13x)=0
We add all the numbers together, and all the variables
-2x+5=0
We move all terms containing x to the left, all other terms to the right
-2x=-5
x=-5/-2
x=2+1/2
Step-by-step explanation:
hope this helps
