Acompany produces boxes of dvds of a rate at 52 boxes per hour. they begin to produce boxes when they first open for the day and after 3 hours they have 404 boxes in stock. how many boxes are in stock when they open? write a linear model for the amount of boxes b ,of a function of the number of hours since they opened ,h. what is the slope of the linear model you found above ? what is the y-intercept of the linear function you found above? use your model to predict the number of boxes in stock at the end of an 8 hour shift

this number 1 and 2  is the only one i could answer

Step-by-step explanation:

1.In three hours, at 52 boxes an hour, they produce 3(52) = 156 boxes.

If they then have 404 boxes on hand, they must have had

404 - 156 = 248 boxes when the store opened.

2.N=404-3 times 52

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
