Answer:
208.6 gal/min
Step-by-step explanation:
For 2" pipe,
Given Volume = 463.2 gal, time = 12 min
flow rate for 2" pipe
= Volume ÷ time
= 463.2÷12
= 38.6 gal/min
For 4" pipe,
Given Volume = 1730.4 gal, time = 7 min
flow rate for 4" pipe
= Volume ÷ time
= 1730.4÷7
= 247.2 gal/min
Difference in flow rate = 247.2 - 38.6 = 208.6 gal/min
The difference in flow rate between a 2-inch and 4-inch pipe, based on Janice's data, is 208.6 gallons per minute.
To determine the difference in flow rate between a 2-inch and a 4-inch pipe, we first need to calculate the flow rate for each pipe. This can be done by dividing the amount of water that flowed within a given time by that time.
For the 2-inch pipe: 463.2 gallons flowed in 12 minutes, so the flow rate is 463.2 / 12 = 38.6 gallons per minute.
For the 4-inch pipe: 1730.4 gallons flowed in 7 minutes, so the flow rate is 1730.4 / 7 = 247.2 gallons per minute.
Now, to find the difference in flow rate between the two pipes, we subtract the smaller flow rate from the larger one. Thus, 247.2 - 38.6 = 208.6 gallons per minute.
Therefore, the difference in flow rate between a 2-inch and 4-inch pipe, based on Janice's data, is 208.6 gallons per minute.
#SPJ3
Answer:
90 mi/h
Step-by-step explanation:
Calculate speed, distance, or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown sdt value given two known values.
Time can be entered or solved for in units of seconds (s), minutes (min), hours (hr), or hours and minutes and seconds (hh:mm:ss).
To solve for distance use the formula for distance d = st, or distance equals speed times time.
distance = speed x time
Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.
distance = rate x time
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
speed = distance/time
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
time = distance/speed

Answer:
The imaginary part is: z = 19
Step-by-step explanation:
For real numbers a and b, a number written in form a+bi is called a acomplex number. The value a is called the real part and b is called the imaginary part of complex number.
Answer:
Here we have the case where:
"one chip is eaten in 1/4 mins."
(that means unit rate, the amount of a given variable that we need to do a unit of another variable)
Then the unit rate would be:
4 chips per minute.
Or, in a more mathematical way to write this:
4 chips/min.
Now we could write this in other units, for example.
We know that 1 min = 60s.
Then we have that (1/4) min = 60s/4 = 15s.
Then we have the unit rate:
1 chip every 15 seconds, or:
(1/15) chips/second.
Now, the variable in this case is time, t = time, let's multiply bot our unit rates by the same amount of time, and see if we have the same outcome.
Let's use t = 2 min.
1) (4chips/min)*2min = 8 chips.
2) ((1/15) chips/second)*2min
First, 2 min = 120 seconds.
((1/15) chips/second)*2min = ((1/15) chips/second)*120seconds = 8 chips.
So both unit rates are equivalent.
