Answer:
32 gallons
Step-by-step explanation:
A standard showerhead in Marty's house dispenses 7 gallons of water per minute. If he showers for 8 minutes, he uses:
1 minute = 7 gallons
8 minutes = x
x = 7 × 8 minutes = 56 gallons of water
We are told that:
Marty changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x
The equation for the energy saving shower:
y = 3x
Where x is the number of minutes spent in the shower
For 8 minutes
y = 3 × 8
y = 24 gallons
The gallons of water Marty saved each day with the change in showerheads if he uses the shower for 8 minutes each day is calculated as:
56 gallons - 24 gallons
= 32 gallons
Answer:
plot points:
(0, 5)
(3, 5)
(3, 0)
Step-by-step explanation:
The actual price of a new lacrosse stick = $29
Percentage of discount given = 10%
Then
Amount of discount that is given = (10/100) * 29 dollars
= 29/10 dollars
= 2.9 dollars
So
The new price of the lacrosse stick = (29 - 2.9) dollars
= 26.10 dollars
So the new price of the lacrosse stick on display will be $29.10 dollars. I hope there is nothing complicated in the procedure for you to not understand. In future you can always use this procedure for solving similar problems without requiring any additional help from outside.
Time = Distance / Speed [ Already mentioned ]
Then, substitute the known values,
t = (9.6 × 10⁶) / (3 × 10⁸)
t = 3.2 × 10⁻² s
In short, Your Answer would be Option B
Hope this helps!
