Answer:
a) -3 gallons per hour
b) y = -3x +14
Step-by-step explanation:
Rate of change is computed by dividing the amount of change by the interval over which it occurred.
<h3>a)</h3>
Here the amount of gas decreased from 14 to 2 gallons, so a decrease of 14-2 = 12 gallons. That occurred over a 4-hour period, so the rate of change is (-12 gallons)/(4 hours) = -3 gallons/hour.
__
<h3>b)</h3>
The initial amount was 14 gallons, so the equation for the line describing remaining gas will be ...
y = -3x +14 . . . . gas in the tank after x hours
Volume is measured of the objects which are three-dimensional .. And square is just a shape , hence it doesn't have any formula for volume .
.
If you were tryna ask about cube , the formula for cube is s^3
Where s is the side of the cube
Answer:
$18.00
Step-by-step explanation:
Start by working out 10%, that's easy:
15 ÷ 10 = 1.5
That means a 10% tip would be $1.50, so a 20% tip would be twice that amount:
1.50 x 2 = 3
A 20% tip is $3.00, and added on to the original $15.00, the total is $18.00
Answer:
A) ≈22.4 concert attendees might have left early.
B) 605 attendees might leave early.
Step-by-step explanation:
A) 11/100, or 11%, of the sample left early.
11% of all the concert attendees is (11/100) × 2040 ≅ 22.4
attendees who might have left early.
B) 11% of the total attendance is 11% × 5500 = 605 attendees who might
leave early.
Basically it means judging if something is right.
