thank you, have an amazing day :)
Step-by-step explanation:
We can do this in a few steps.
First: If it is 300 ounces per second then how many pounds per second?
1 ounce is 1/16 of a pound.
So we multiply 300 by 1/16.
300 x 1/16 = 300 ÷ 16 = 18.75
Now we know: 300 oz/sec equals 18.75 lbs/sec
But, we want to know how many lbs per minute (lbs/sec)
We need to calculate how many seconds are in a minute.
1 minute = 60 seconds.
We know how many lbs per second.
If we want to know how many lbs per minute, we multiply # of pounds per seconds by 60.
# pounds per second x 60 = # pounds per minute
# pounds per second: 18.75
18.75 x 60 = # lbs/min
18.75 x 60 = 1125
This means that 300 oz/sec => 1125 lbs/min
Comment: Wow, you have at least 390 math problems. That is insane! I've never had to do "the 390th math problem"!
You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
