Answer: The Surface area is 72 units
Step-by-step explanation:
2*(3*6+2*6+2*3)=72
Area = length × width
2 × 3 = 6
6 ft²
Using y to represent number of bottles filled in x minutes, y = 250x.
This is rather basic, and I urge you to think about it so that it's very clear to you, and you will be able to do similar problems on your own in the future.
The graph will be a straight line passing through the origin (0,0).
The area of a triangle is 1/2(h*b). We know the height is 7.794 and the base is 9 so just plug and chug!
1/2(7.794*9)= 35.073
<span>Lets use x to represent how much each person spent.
Jolly's amount = xPauline's amount = yHarry's amount = 3y (he spent 3 times more than Pauline)
1. Set up 2 equations:
Jolly + Pauline = $1440 x + y = 1440
Jolly + Harry = $2658x + 3y = 2658
2. Put the equations in terms of x ( x = ______)
Jolly + Pauline x + y = 1440In terms of x: x = 1440 - y
Jolly + Harry x + 3y = 2658In terms of x: x = 2658 - 3y
3. Set the two equations equal to each other (so we can find the value of y, pauline’s amount)
If x = (1440 - y) and x also = (2658 - 3y), then 1440 - y must = 2658 - 3y
1440 - y = 2658 - 3y
4. Move like terms to the same side to find the value of y (pauline’s amount)-y + 3y = 2658 - 14402y = 1218
y = 1218/2y = 609
Pauline spent $609 total
5. Find out how much Jolly spentFrom earlier steps we found Pauline spent $609.We know that Pauline and Jolly spent a joint total of $1440, so subtract 609 from 1440 to find Jolly’s amount
1440 - 609 = 831
Jolly spent 831 dollars total.
Hope this answers your question, and May the Force Be With You!
