Ok so look for the change between x and y.
Answer:
<u>Yes they are equivalent.</u>
Step-by-step explanation:
Use PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
Distribute or multiply -3 with 2p and 4 to get -6p and -12.
You will then have 18-6p-12-3p, simplify to get 6-9p
For the second equation multiply 3 with 2 and -3p, you will then get 6-9p as well.
They are equal, hope the helps ;)
This is a matter of Amount = Rate times time.
First, find the area of the circular opening. A = pi (r^2). Here,
A = pi(10.5 inches)^2.
To obtain the volume of water that flows out of the pipe per second, multiply this area by the 30 inches per second rate.
That comes out to a volume per second of Volume rate = pi*(10.5 inches)^2 * 30 inches per second:
Volume rate = 3.14(110.25 in^2)(30 inches/sec)
= 10390.8 cubic inches per second
Convert this result to cubic feet per second. Recall that 1 cubic foot = (12 inches)^3, or 1728 cubic inches / 1 cubic foot.
Thus, 10390.8 cubic inches per second comes out to
10390.8 cubic inches
---------------------------- = Just over 6 cubic feet per sec.
1728 cu. inches
---------------------
1 cu. ft
How many sec in 1 day? 1 day = 24 hours
1 hour = 60 minutes
60 seconds = 1 minute
Figure out how many seconds there are in 1 day, and then multiply your result by 6 cu. ft. / sec.
