let X be amount of time in seconds
the slope intercept form is y=mx+b
fill in the variables: y=30x
The correct answer is y=30x
Answer:
[5 2.6 8 2]
Step-by-step explanation:
For this we simply add the digits
A+ B
[3+2 2+.6 0+8 -1+3]
[ 5 2.6 8 2]
P = 2(L + W)
P = 360
L = 5W
360 = 2(5W + W)
360 = 2(6W)
360 = 12W
360/12 = W
30 = W <=== width
L = 5W
L = 5(30)
L = 150 <=== length

<h3>
Answer:</h3>
6 hours
<h3>
Step-by-step explanation:</h3>
The two hoses together take 1/3 the time (4/12 = 1/3), so the two hoses together are equivalent to 3 of the first hose.
That is, the second hose is equivalent to 2 of the first hose. Two of the first hose could fill the vat in half the time one of them can, so 6 hours.
The second hose alone can fill the vat in 6 hours.
_____
The first hose's rate of doing work is ...
... (1 vat)/(12 hours) = (1/12) vat/hour
If h is the second hose's rate of doing work, then working together their rate is ...
... (1/12 vat/hour) + h = (1/4 vat/hour)
... h = (1/4 - 1/12) vat/hour = (3/12 -1/12) vat/hour = 2/12 vat/hour
... h = 1/6 vat/hour
so will take 6 hours to fill 1 vat.
