On a recent trip to the convenience store, you picked up 3 gallons of milk, 4 bottles of water, and 7 snack-size bags of
chips. Your total bill (before tax) was $23.40. If a bottle of water costs twice as much as a bag of chips, and a gallon of
milk costs $2.20 more than a bottle of water, how much does each item cost?

The value of  the height of the water at  midday  is 14 feet.

Height, altitude, and elevation all refer to the vertical distance between something's top and bottom or its base and something above it. Height is used to describe everything that may be measured vertically, high or low.

Similarly, we will determine the height at other times during the day, at midday . we have the value $t=3$, so using the formula, we have

[tex]H(3)=10+4 \sin \left(\frac{\pi}{6} \cdot 3\right)=10+4 \cdot \sin \frac{\pi}{2}[/tex]

Taking into account that

Step-by-step explanation:

Formula we use,

→ 192 hours

Hence, there are 192 hours.

Answer:

4) Melody is 9 and her sister is 24

5) The numbers are 3 and 9

6) 14 feet per second

Step-by-step explanation:

Questions 4

There is a lot going on here.  This is probably hard to follow.  If it is, it is me and not you.

Let m = Melody and s = sister

m - 4 = 1/4(s-4)                     m + 6 = 1/2(s + 6)  Clear the fractions

4m - 16 = s -4                        2m -s = -6

Multiple the second equation by -1 and add together

4m - s = 12

-2m + s = 6

2m = 18  Divide both sides by 2

m = 9  Substitute this in to find the sister's age

2m + 12 = s + 6

2(9) +12 + s + 6

18 + 12 = s + 6

30 = s + 6  Subtract 6 from both sides

24 = s

Questions 5

x + y = 12              x = 5y - 6

Plug in 5y - 6 in the first equation for x

5y - 6 + y = 12  Combine like terms

6y - 6 = 12  Add 6 to both sides

6y = 18  Divide both sides by 6

y = 3

x + y = 12

3 + y = 12  Subtract 3 from both sides

y = 9

I am little confused by this because it says, "The value of the number..."  What number are they referring to?

Question 6

To find the rate taking into consideration the walkway rate:

[tex]\frac{48}{3}[/tex] - w  Which is equivalent to 16 - w

[tex]\frac{24}{2}[/tex] + w  Which is equivalent to 12 + w

Set these expression equal to each other and find the rate of the walkway

16 - w = 12 + w  Add w to both sides

16 = 12 + 2w  Subtract 12 from both sides

4 = 2w  Divide both sides by 2

2 = w

The rate of the walkway is 2 feet per second.  Subtract that from 16 or add is to the 12 to get 14 steps per second.

I'm assuming your equation was:

        [tex]y-2=\dfrac{1}{5}(x-3)[/tex]

Both Jules' line and Lauren's line have a slope of -5 or [tex]-\dfrac{5}{1}[/tex] and those two lines are parallel since they have the same slope.

Answer:

To describe the temperatures for the week, we can apply the following statistical tools:

a) Find the mean, median, mode, and range.

c) Construct a line graph.

d) Construct a stem and leaf plot.

We can describe temperatures using measures of central tendencies (especially the mean, median, and mode).

The mean temperature is the average, which shows the overall trend in temperature changes.  It is computed by adding up the temperatures for the period and diving by the number of data values.

In addition, the median gives the middle value when the data set is ordered in ascending or descending orders. Similarly, the mode gives the highest temperature occurrence within the period. It may not be useful here.

We can estimate the difference between the highest and lowest temperature for the week with the range.

A line graph (showing connecting lines) and a stem-and-leaf plot (like a bar graph) can graphically describe the temperatures for the week.

Thus, we can use Options A, C, and D to describe the temperature.

To have the same price, 40 stickers will have to be ordered and the equation is 16 = 0.40p.

What is the equivalent equation?

Equivalent equations are algebraic equations with identical solutions or roots. Adding or subtracting the same number or expression from both sides of an equation yields an equivalent equation. An equivalent equation is created by multiplying or dividing both sides of an equation by the same non-zero number.

We have,

for company A :

Design Fee = $30

Costvper sticker = $0.80

for company B :

Design Fee = $14

Cost per sticker = $1.20

Let the number of stickers = p

Total cost of company A = 30 + 0.80p

Total cost of company B = 14 + 1.20p

For the cost to be the same :

Company A = Company B

30 + 0.80p = 14 + 1.20p

Collect like terms :

30 - 14 = 1.20p - 0.80p

16 = 0.40p

p = 16/0.40

p = 40 stickers

Therefore, to have the same price, 40 stickers will have to be ordered and the equation would be 16 = 0.40p.

Therefore the total surface area of the cylinder is 157 square feet.

The number of tiles that would be required to cover a floor that is 288 square feet is 512.

According to the question,

We have the following information:

Area of the tile = 9*9 square inches

Area of the tile = 81 square inches

Area of the floor = 288 square feet

So, we will convert the area of the floor from square feet to square inches.

We know that 1 feet = 12 inches.

So, we have the following expression:

Area of the floor = (288*12*12) square inches

Area of the floor = 41,472 square inches

Number of tiles required to cover the floor = area of the floor/area of the tile

Number of tiles required to cover the floor = 41,472/81

Number of tiles required to cover the floor = 512

Hence, the number of tiles that would be required to cover a floor that is 288 square feet is 512.
