Answer:
Answer
Step-by-step explanation:
OK, there are 360 students in the whole school and 15 classes there, too.
Each class has an EVEN amount of students, so simply, all you need to do is divide (360 divided by 15)
5/30 were absent or 1/6 simplifying or dividing both by 5 we have: 1/6
Answer:
D
Step-by-step explanation:
-2x(x+3)
-2x-6
Jill ran faster. I know because I compared both of their unit rates.
Jack's unit rate is 5/42.5 = 0.118 mile per minute (rounded)
Jill's unit rate is 3/23.25 = 0.129 mile per minute (rounded)
Jill runs a greater part of a mile per minute than Jack does.
She is faster. There's no getting around it.
Answer:
The equation is
![f(x) = [\frac{x}{13}]](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5B%5Cfrac%7Bx%7D%7B13%7D%5D)
Where x is the ribbon's length in ft and with [a] we denote the integer part of a real number a.
Step-by-step explanation:
In order to obtain how many pieces of ribbon Lei can make, we have to divide the length of the Ribbon by the length of each piece, which is 13 ft. This means that if we have x ft of ribbon, then Lei can make a total of x/13 pieces.
However, if the result we obtain is not an integer we need to discard the last part of the ribbon that couldnt form and entire piece of 13 ft, therefore, after we divide x by 13, we also need to take the integer part of that division, that is, the biggest integer that is not bigger than x/13. With this information in mind, we obtain that the amount of pieces Lei can make is given by the following formula:
![f(x) = [\frac{x}{13}]](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5B%5Cfrac%7Bx%7D%7B13%7D%5D)
Where [ a ] denotes the integer part of a real number a.
