Answer:
4.09 m
Step-by-step explanation:
Let the length of the shadow cast by a person be x m.
![\tan \: 24 \degree = \frac{height \: of \: person}{length \: of \: the \: shadow} \\ \\ 0.4452286853 = \frac{1.82}{x} \\ \\ x = \frac{1.82}{0.4452286853} \\ \\ x = 4.08778693 \: m \\ x = 4.09 \: m](https://tex.z-dn.net/?f=%20%5Ctan%20%5C%3A%2024%20%5Cdegree%20%3D%20%20%5Cfrac%7Bheight%20%5C%3A%20of%20%5C%3A%20person%7D%7Blength%20%5C%3A%20of%20%5C%3A%20the%20%5C%3A%20shadow%7D%20%20%5C%5C%20%20%5C%5C%200.4452286853%20%3D%20%20%5Cfrac%7B1.82%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B1.82%7D%7B0.4452286853%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%204.08778693%20%5C%3A%20m%20%5C%5C%20x%20%3D%204.09%20%5C%3A%20m)
Answer:28inches & 84inches
First, lets write an equation that fits the data given. The string is 112 inches long. When the two pieces are cut, the first piece will be three times as long as the second piece. If we use the variable, x, to represent the second piece, we can create the following equation...
112=3x+x
Now lets solve for x.
112=4x
divide both sides by 4
28 inches=x
Now we know that the second piece is 28inches long. Since the first piece is three times as long, simply multiply 28*3 and we'll know the length of the first piece.
28*3=84 inches
28+84=112
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

hi
Step-by-step explanation:
I can't figure out a factor for this but graphing it shows x = -2 and +1 as real roots.
