Dominique is buying water. She needs 2 liters. A half-liter of water costs $2.46. A 250-milliliter container of water costs

Andrew [12]

Answer:

$\fbox{\begin{minipage}{15em}A half-liter of water costs 2.46$\end{minipage}}$

Step-by-step explanation:

Dominique wants to buy $2$ liters of water.

Case 1:

A half-liter of water costs $2.46$ .

The $2$ half-liters is $1$ liter => The cost of a liter of water ( $A$ ) is calculated by multiply the cost of $1$ half-liter by $2$ :

$A = 2.46$ x $2$ = $4.92$

=> The cost of two liters: $A_{1}$ = $A$ x $2$ = $4.92$ x $2$ = $9.84$ $

Case 2:

A quarter-liter of water costs $1.48$ .

The 4 quarter-liters is $1$ liter => The cost of a liter of water ( $B$ ) is calculated by multiply the cost of $1$ quarter-liter by $4$ :

$B = 1.48$ x $4$ = $5.92$

=> The cost of two liters: $B_{1} = 5.92$ x $2$ = $11.84$ $

Compare $A_{1}$ and $B_{1}$ , the cost of second buying method is more expensive.

=> She should buy the water, in which a half-liter of water costs $ $2.46$

Hope this helps!

Please help me find the value of x!

dlinn [17]

Answer:

x = 27

Step-by-step explanation:

line AC and DE are parallels, so the extra angle in the triangle would be 2x because they are corresponding angles.

A triangle adds up to 180, so the equation would be 180 = 72 + 2x + 2x

Markups The depth of water in a pond increases by 3% after a heavy rain. If the average depth of the water was 8.3 feet, what is

jek_recluse [69]

Answer: 8.55 feet

Step-by-step explanation:

We should equal the average depth to 1, so if it raises 3%, it raises 0.03. Simply add the original (1) plus what it rose (0.03) and multiply the original by that, so 8.3 × 1.03 = new depth. The result is 8.549 feets.

Pick two points (0,1) (1,4)

m = (y2-y1)/(x2-x1)

=(4-1)/(1-0)

=3/1

The rate of change is 3 dollars per guest
