Answer:
will flow from the hose in 45 minutes.
Step-by-step explanation:
The line of best fit for the scatter plot can be described by the equation :
y is amount of water in gallons
x is time
When x = 45 minutes, put x = 45 in above formula as :
So, will flow from the hose in 45 minutes.
V + 4 = -2(x - 1)
v + 4 = -2x + 2
v = -2x - 2. [ Final answer]
Hope this helps!
The cost price of the table is $40.
<h3>What is Gain ?</h3>
Gain is the amount gain by selling the product at a higher price than its cost.
Let the cost of the table is $ x
The percentage gain is x% (as given in the question)
Cost price = ?
It is known that
Step 1 : Gain = ( selling Price - Cost Price) * 100 / Cost Price
Selling price = 56
Cost Price = $ x
Therefore substituting the value
x = (56 - x) * 100 / x
x² = 5600 - 100x
x² +100x -5600 = 0
Step 2 : Factorizing
x² + 140x - 40 x -5600 = 0
x( x+14 ) -40( x +14) = 0
( x - 40)(x +14) = 0
x = $40
Therefore the cost price of the table is $40.
