Meyer restocks on toilet paper Sunday they get 800 rolls. They are open Monday through Sunday 8am to 10pm. They sell 16 rolls pe
ohaa [14]
Remember 800 because that’s your big number / most important.

So they’re open from 8am - 10pm. They’re open for 14 hours a day and they sell 16 rolls per hour.
If one hour is 16 rolls sold , then what is 14?
16 x 14 hours (16 x 14 = 224)
In a whole day they sell 224 rolls.
Monday: 800 rolls - 224 rolls = 576 rolls
Tuesday: 576 rolls - 224 rolls = 352 rolls
Wednesday: 352 rolls - 224 rolls = 128
By Thursday they won’t be able to sell more than 224 because there is only 128 rolls left that will be sold out in 8 hours on that day.
So they will be sold out completely by THURSDAY.
The best time to go to the store is most likely on a Tuesday around 12-1pm

Use a diagram to name each of the following pairs of angles. If the name doesn't exist say none​
nirvana33 [79]

Answer:

  see below

Step-by-step explanation:

This is a vocabulary problem, identifying the names of things on a diagram.

Angles are "interior" when they are between the "parallel" lines. They are "exterior" when they are outside those lines. They are "alternate" if they are on opposite sides of the transversal, and "same side" if they are not.

They are "vertical" if they share a vertex and have opposite rays for sides, and they are "corresponding" if they are in the same quadrant of the intersection of crossing lines. (1, 5, 9, 13 are "corresponding", for example.)

Two times the least of three consecutive odd integers exceeds three times the greatest by 15
Mariana [72]
Three consecutive odd integers would be x, x+2, and x+4 assuming x is an odd integer. The smallest of these is x. Two times x is 2x. The greatest integer is x+4. Three times this is 3 (x+4), and if you distribute you get 3x+12. If 2x exceeds this by 15, you would make it 3x+12-15. If you add the like terms, 12+(-15) is -3. So, you have 2x=3x-3. Subtract 3x from both sides. 2x-3x is -1x, or -x. Now we have -x=-3. Divide by -, or -1 on both sides. Now we have x=3. You can substitute x for 3 for any of the consecutive odd integers to find their value.

1.3×5=6.5
So that means Alonzo will need 6.5m at least amount of fabric.
