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.

Sierra drives for h hours at a rate of 2x miles per hour. Which expression shows the distance that she drives after h hours
Eva8 [605]

Answer:

Distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh

Explanation:

Distance traveled by a body = Velocity of the body * Time taken by the body

Here velocity of Sierra =  2x miles per hour

Time taken by Sierra = h hours.

Distance traveled by Sierra = 2x * h = 2xh

So distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh

6x+3y=6  and 8x+9y= -22  describes the outcomes of Clare and Noah.

Step-by-step explanation:

Let,

x represents the number of points for a goal.

y represents the number of points for a penalty.

Therefore,

6 goals = 6x

3 penalties = 3y

8 goals = 8x

9 penalties = 9y

According to given statment;

6x+3y=6    Eqn 1

8x+9y= -22   Eqn 2

6x+3y=6  and 8x+9y= -22  describes the outcomes of Clare and Noah.

A retail store is offering a series discount of 10/10 on a dishwasher with a list price of $346. Find the net cost after the ser
lutik1710 [3]
$346/100=$3.46  =1% of $346.  So, giving 10% discount we $3.46*90=$311.40

Again, $311.40/100=$3.114, providing, 10% discount we get $3.114*90=$280.26.

The net cost after the series discount is $280.26
