Answer: 5 cents

Step-by-step explanation:

Given

Flow rate of water is 3.5\ gal/min

At this rate it cots \$1.90 for 10 minutes

Volume that flown in this time

\Rightarrow V=3.5\times 10\\\Rightarrow V=35\ \text{Gallons}

So, \$1.90 is charged for 35 gallons of water

Using unitary method, 1 gallon costs

\Rightarrow 1\ \text{gallon}=\dfrac{1.9}{35}\\\\\Rightarrow 1\ \text{gallon}=\$0.0542\ \text{or}\ 5.4\ \text{cents}\\\text{Round off to nearest cent}\\\Rightarrow 1\ \text{gallon}=5\ \text{cents}

Antonia bought a set of dishes, a towel, and a candle at a housewares store. The set of dishes cost $35.02, the towel cost $21.4
vekshin1

Answer:

Antonia saved $5.39

Step-by-step explanation:

Candle:

$9.59 - $0.50 (coupon) = $9.09

Towel:

$21.43 - $2.75 (coupon) = $18.68

Dishes:

$21.43 x 10% = 2.143

$21.43 - $2.143 = $19.287, rounded to the nearest cent and it’s $19.29.

Calculate the amount of money saved by adding 0.50 + 2.75 + 2.143, which is 5.393. Round to the nearest cent and it will be $5.39.

The graph of 15x + 7y = 15 is shown on the grid. Which ordered pair is in the solution set of 15x + 7y ≥ 15?
elena55 [62]

Answer:

The correct option is c.

Step-by-step explanation:

The given equation is

15x+7y=15

The given inequality is

15x+7y\geq 15

A point will contained in solution set if the above inequality satisfied by that point.

Check the point (0,-3),

15(0)+7(-3)\geq 15

-21\geq 15

This statement is false, therefore option a is incorrect.

Check the point (-3,0),

15(-3)+7(0)\geq 15

-45\geq 15

This statement is false, therefore option b is incorrect.

Check the point (3,3),

15(3)+7(3)\geq 15

66\geq 15

This statement is true, therefore option c is correct.

Check the point (-3,-3),

15(-3)+7(-3)\geq 15

-66\geq 15

This statement is false, therefore option d is incorrect.
