Caissa can download a maximum of 1000 megabytes (MB) of songs or movies to her smartphone each month. The file size of each movi
Firdavs [7]

Answer:

85M + 4S <u><</u> 1000

Step-by-step explanation:

An inequality represents an expression that can have different values as long as the value is within the range given.  In this case, the number of songs and movies that Caissa can download can not exceed 1000 MB.  Since each move is 85 MB and each song is 4 MB, then any combination of these two files combined must not be larger than 1000 MB.  Using the variable (M) for movies and (S) for songs, we can set up an expression 85M + 4S to represent the number of movies times 85 for each movie and the number of songs times 4 for each song.  Since the total can be no greater than 1000, the expression would be less than or equal to (<u><)</u> 1000 MB.

A backyard pool has a concrete walkway around it that is 5' wide on all sides the total area of the pool and the walkway is 950'
Soloha48 [4]

The dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0

<h3>How to determine the dimension</h3>

For the pool, we have that;

Let the width = x feet

Length = (x+8) feet

The pool alongside the walkway gives;

Width = x + 5 + 5 = (x + 10) feet

Length = x + 8 + 5 + 5 = (x + 18) feet

Total area of the pool with walkway = 950 square feet

Note that formula for area is given as

Area = length * width = 950

Equate the length and width

(x+18)  × (x + 10) = 950

Using the  FOIL method, we have;

(x × x )+ (x × 10) + (18 × x) + (18 × 10) = 950

x² + 10x + 18x + 180 -950 = 0  

collect like terms

x² + 28x - 770 = 0

Thus, the dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0
