Answer:
a. 3/5 liters per hour
b .06 hours
Step-by-step explanation:
Change 40 minutes to a fraction of an hour
40 minutes/ 60 minutes = 2/3 hour
It takes 1 2/3 hours to fill the container
Changing to an improper fraction
(3*1+2)/3 = 5/3 hours
We want liters per hour
1 liter per 5/3 hours
1 ÷ 5/3
Copy dot flip
1 * 3/5 = 3/5 liters per hour
Change 100 ml to liters
We know 1000 ml = 1 lt
100 ml * 1 lt/1000 ml = .1 lt
So 100 ml = .1 lts
.1 lt * 3/5 lt per hour
Changing the fraction to a decimal
.1 lt * .6 lt per hour
.06 hours
Answer:
Step-by-step explanation
larger angle = 76+2x
smaller angle = x
supplementary angles add up to 180
∴(76+2x)+x=180
76+3x=180
3x= 180-76
3x = 104
x = 104/3
x = 34.7°(smaller angle)≈ 35
larger angle = 76+2(34.7)
=76+69.4
=145.4≈ 145
To simplify this, you would have to turn b^-2 into a positive exponent.
To do this, we have to flip b^-2, which would get rid of the negate from the exponent: -2
3a^4 b^-2 c^3 / b^-2
Then we get the answer:
3a^4 c^3
------------
b^-2
I have a picture to clarify!
I hope this helped, let me know if you don't understand! ^.^
Answer:
There are 26 investors which contributed 6,000
And 34 investors which contributed 3,000
Step-by-step explanation:
You need to set up a two equation problem
Now you have to clear "x" or "y" from the second equation:
And replace on the first equation:
And now you use this "x" vale on the second equation
There are 26 investors which contributed 6,000
And 34 investors which contributed 3,000
Answer:
2 m/s
Step-by-step explanation:
Since speed is total distance over time, we first need to find the total distance the car traveled.
Total distance = 200 + 80 + 120 = 400 m
total time = 200 sec
speed = distance/time = 400/200 = 2 m/s
