Answer:

  $735

Step-by-step explanation:

We assume the cover needs to cover the pool only, not any extra area around the pool.

The cost is given per square foot, so to find the total cost, we need to know how many square feet the cover must cover. The cost will be found by multiplying the cost per square foot by the number of square feet.*

The dimensions of the pool are given as 35 ft by 70 ft. The pool area is the product of these dimensions.

  A = LW

  A = (70 ft)(35 ft) = 2450 ft²

Then the cost is ...

  C = ($0.30/ft²)(2450 ft²) = $735

The cost to buy a pool cover is $735.

__

* This is the same rule you use for any purchase. The total cost is the cost per item multiplied by the number of items. Here, each "item" is 1 square foot of pool cover.

Brady creates the graph below to keep track of the approximate height of the grass on his
IgorC [24]

Answer:

<h2>Time is the independent variable and Height of the Grass is the dependent variable.</h2>

Step-by-step explanation:

The graph is about the height of the grass thourgh time, that means Brady is analysing how long it takes to the grass to grow.

It's important to know that time is a variable which doesn't depends on any other variabel, that is, it's an independent variable all the time.

Therefore, Time is the independent variable and Height of the Grass is the dependent variable.

This is just simple deduction, because the grass grows through time, it doesn't happen in the opposite way, time doesn't change accoring to the height of the grass.

matrenka [14]

<u>9 bags</u> can be brought

Explanation :-

As per given conditions,

\frac{132.75}{14.75}

Multiplying numerator and denominator to get positive values,

\frac{132.75 \times 100}{14.75 \times 100}

=  > \frac{13275}{1475}

Now by normal division, we get,

-2x-1 is less than or equal to 5 how can you solve it
aniked [119]
<u>Answer</u>

x ≥ -2


<u>Explanation</u>
The inequalities are solve the same way as algebra. This would be solve as follows. 
-2x-1≤5
-2x≤5+1
-2x≤4

Divide both sides of the inequality by -2. This will change the sign from ≤ to ≥.

(-2x)/(-2) ≤ 4/(-2)
x ≥ -2
