coca-cola $1.29 for 1.25 L or Pepsi $2.49 for 2 L.find the unit price of each and choose the better deal.

lys-0071 [83]

Answer:

Coca Cola

Step-by-step explanation:

To find the unit price, divide the cost by the amount

Coca-Cola:

cost/amount

1.29/1.25=1.032

Rounded to the nearest cent: 1.03

Pepsi:

cost/amount

2.49/2=1.245

Rounded to the nearest cent: 1.25

So, Coca Cola is the better deal

Hope this helps! :)

Note that $\displaystyle{ \sin30^{\circ}= \frac{1}{2}$ and $\displaystyle{ \cos30^{\circ}= \frac{ \sqrt{3}}{2}$ .

From the unit circle, we can check that $\sin30^{\circ}$ and $\sin(-30)^{\circ}$ have the same value, but opposite signs, that is:

$\sin(-30)^{\circ}=-\sin(30)^{\circ}=-\frac{1}{2}$ .

Thus,
$\displaystyle{ \cos(x-y)= \cos(-30^{\circ}-60^{\circ})=cos(-90^{\circ})$ .

Note that $cos(-90^{\circ})$ is the x-coordinate of the lowest point on the unit circle, that is (0, -1). Thus $cos(-90^{\circ})=0$

On Thursday, the amount of snowfall was 1/8 cm. On Wednesday, the amount of snowfall was 4 1/4 cm. What was the amount of snowfa

marysya [2.9K]

The total amount of snowfall on the two days combined is 4 3/8 cm

<h3>Addition of fractions </h3>

From the question, we are to determine the amount of snowfall on the two days combined

From the given information,

the amount of snowfall was 1/8 cm on Thursday

The amount of snowfall was 4 1/4 cm on Wednesday

Then,

The total amount of snowfall on the two days combined will be

$\frac{1}{8}+4\frac{1}{4}$ cm

= $\frac{1}{8}+\frac{17}{4}$

= $\frac{1+34}{8}$

= $\frac{35}{8}$

= $4\frac{3}{8} \ cm$

Hence, the total amount of snowfall on the two days combined is 4 3/8 cm

Maleah turned on the water in the kitchen. For every 1 3/4 minute, 1 2/3 gallons of water went into the sink. How many gallons o

dolphi86 [110]

Answer: 20/21 gallons

Step-by-step explanation:

From the question given, we are informed that Maleah turned on the water in the kitchen and that for every 1 3/4 minute, 1 2/3 gallons of water went into the sink.

The number of gallons of water that filled the sink per minute will then be calculated as:

= Amount of gallons of water that went into sink / Number of minutes used

= 1 2/3 ÷ 1 3/4

= 5/3 ÷ 7/4

= 5/3 × 4/7

= 20/21

Therefore, 20/21 gallons of water filled the sink per minute
