Answer:

The answer is below

Step-by-step explanation:

The volume of a cuboid is the product of its length, height and breadth. It is given by:

Volume = length × breadth × height

Since the volume is given by the expression 12y² + 8y - 20. That is:

Volume = 12y² + 8y - 20 = 4(3y² + 2y - 5) = 4(3y² + 5y - 3y -5) = 4[y(3y + 5) -1(3y + 5)]

Volume = 4(y-1)(3y+5)

Or

Volume = 12y² + 8y - 20 = 2(6y² +4y - 10) = 2(6y² + 10y - 6y -10) = 2[y(6y + 10) -1(6y + 10)]

Volume = 2(y-1)(6y+10)

Therefore the dimensions of the cuboid are either 4, y-1 and 3y+5 or 2, y-1 and 6y+10

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to th
aleksklad [387]

Answer:

As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.

Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.

Subtract the 2 hours from 10am:

= 10 - 2

= 8am

Subtract the 15 minutes from 45:

= 45 - 15

= 30

Put that together:

= 8:30 am

<em>They left their house at 8:30 am using this scenario. </em>

Part A. Solve -np - 80 &lt; 60 for 'n'. Show your work.
skelet666 [1.2K]
Part A: 
- np -80 <60
Adding 80 both sides
- np < 140
Dividing by -p both sides
n > -140/p
Part B:
2a - 5d =30
5d = 2a-30
d= (2a-30)/5

Samia normally works 8 hours a day and earns $X per hour. For each hour she works
Inga [223]

9514 1404 393

Answer:

  $(4/3)X

Step-by-step explanation:

Working 12 hours, Samia gets paid for the first 8 hours ...

  8 · ($X) = $8X

For the remaining 4 hours, she is paid ...

  4 · ($2X) = $8X

Then for 12 hours, she is paid a total of ...

  $8X +$8X = $16X

Her average hourly pay is then ...

  total pay / total hours = $16X/12 = $(4/3)X . . . average hourly pay
