a 32 ounce bottle of apple juice for$2.50 or a 48 ounce bottle for$3.84

Answers

Final answer:

To determine which bottle of apple juice is a better value, calculate the cost per ounce by dividing the price by the number of ounces. The 32 ounce bottle at $2.50 has a slightly lower cost per ounce than the 48 ounce bottle at $3.84.

Explanation:

The student is asking to compare the cost per ounce of two different sizes of apple juice to determine which offers the better value. To do this, you would divide the price of each bottle by the number of ounces it contains to get the cost per ounce for each. Then, you compare these two values.

For the 32 ounce bottle: $2.50 / 32 ounces = $0.078125 per ounce

For the 48 ounce bottle: $3.84 / 48 ounces = $0.08 per ounce.

Although the prices per ounce are very close, the 32 ounce bottle is slightly cheaper per ounce.

Final answer:

To determine the better deal between a 32-ounce bottle of apple juice for $2.50 and a 48-ounce bottle for $3.84, we need to calculate the cost per ounce for each option. The 32-ounce bottle of apple juice is a better deal as it has a lower cost per ounce.

Explanation:

To determine the better deal between a 32-ounce bottle of apple juice for $2.50 and a 48-ounce bottle for $3.84, we need to calculate the cost per ounce for each option.

The cost per ounce for the 32-ounce bottle is $2.50/32 = $0.078125.

The cost per ounce for the 48-ounce bottle is $3.84/48 = $0.08.

Therefore, the 32-ounce bottle of apple juice is a better deal as it has a lower cost per ounce.

Step-by-step explanation:

Six bakers use a total of 12x - 3.6 pounds of flour each hour. If each baker uses the same amount of flour, find an expression for the number of pounds each baker uses in an hour. Then write an expression equivalent to 12x - 3.6 to represent the total hour used in an hour.

Answers

Final answer:

Each baker uses (12x - 3.6) / 6 pounds of flour in an hour. The expression equivalent to 12x - 3.6 to represent the total flour used in an hour is 12x - 3.6 pounds.

Explanation:

To find an expression for the number of pounds each baker uses in an hour, we divide the total amount of flour (12x - 3.6 pounds) by the number of bakers (6). Therefore, each baker uses (12x - 3.6) / 6 pounds of flour in an hour.

To write an expression equivalent to 12x - 3.6 to represent the total flour used in an hour, we can simply use 12x - 3.6 pounds, as this already represents the total amount of flour consumed by all the bakers in one hour.

Final answer:

Each baker uses 2x - 0.6 pounds of flour each hour. The expression 12x - 3.6 represents the total flour used by all bakers in an hour, so it's already the equivalent expression needed.

Explanation:

If six bakers use a total of 12x - 3.6 pounds of flour each hour, and each baker uses the same amount of flour, we need to divide the total amount of flour by the number of bakers to find how much flour each baker uses per hour.

Amount of flour per baker per hour = Total flour used / Number of bakers

= (12x - 3.6) / 6

By simplifying this expression, we divide each term in the numerator by 6:

= 12x/6 - 3.6/6

= 2x - 0.6

So, each baker uses 2x - 0.6 pounds of flour each hour.

To represent the total hour used in an hour with an equivalent expression, we can simply rewrite the original expression, as it already represents the total amount of flour used by all bakers in an hour. Thus, the expression equivalent to 12x - 3.6 is already the total amount used in an hour.

If line BC represents 200% what is the length of a line segment that is 75% explain

Answers

This is really easy, because 8m is 200% you have to divide it in half to figure out the 100% which is 4... now you have to find the 75%. all you have to do is divide 4 by 25% which is 3.
Final answer:

The length of the line segment that is 75% of the line BC is 6 cm.

Explanation:

In this problem, we are given that line BC represents 200% or twice the length of a line segment. Let's say the length of BC is 8 cm. To find the length of a line segment that is 75%, we can use proportion. Since 75% is three-fourths of 100%, the length of the line segment will be three-fourths of the length of BC.

So, the length of the line segment that is 75% is (3/4) * 8 cm = 6 cm.

a scuba diver dives to a depth of 50 feet, sinks 12 feet, then rises 20 feet. what is the diver's final position relative to sea level?

Answers

We can use a number line to help us solve, but I guess "visualizing" it with a vertical number line works too. 

We start at the point 0. We go down to the point -50, after the diver dives down to a depth of 50 feet. "Sink" is to go down, so we go down to -62 because -50-12=-62. "Rise" is to go up, so we go up to -42 because -62+20=-42.

The diver's final position relative to sea level would be at 42 feet.

it takes 1 day to repair 100 meter of road.At this rate how many days will it take to repair 1 kilometer of road?

Answers

This is a simple proportion problem.  Assuming that the rate is constant for how fast the person can repair the road, the number of days it takes to repair the road will be exactly 10 days.

1 day to repair 100 meters
? days to repair 1 kilometer

1 kilometer = 1000 meters
Substitute 1000 meters for 1 kilometer

So set up your proportion as so:
1 day/ 100 meters = x / 1 kilometer
1 day / 100 meters = x/ 1000 meters
x = 10 days
1 km = 1000 m

1/100 = x/ 1000...1 day to 100 m = x days to 1000 m
cross multipy
100x = 1000
x = 1000/100
x = 10 days <==

What is this number written in expanded form with multiplication

2.306

Answers

2 times 1   3 times .1   0 times .01    6 times .001
Just look at each place value of every number in the integer.
Final answer:

The number 2.306 can be written in expanded form with multiplication as 2 x 1 + 3 x 0.1 + 0 x 0.01 + 6 x 0.001.

2.25meters long and 1.8meters wide what is the area of the blanket give the answer in centimeters

Answers

The length is 2.25 meters          The width is 1.8 meters
1 meter =100 centimetres                1 meter=100centimeters
2.25 meters=?                                   1.8 meters=?
2.25m/1m*100cm=225cm                 1.8m/1m*100cm=180 cm
The area of this shape is length *width
A=225cm*180cm
A=40500cm²
Therefore the area in centimeters is 40500cm²

The 1 meter contains 100 centimeters therefore the area of the blanket with dimensions 2.25meters long and 1.8meters wide is 40500 cm².

What is unit conversion?

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

As per the given dimension of the blanket,

Length = 2.25 meters and width = 1.8 meters.

Since,1 meter = 100 cm

Length = 2.25× 100 = 225 cm.

Width = 1.8× 100 = 180 cm

The area of the rectangle is Length × width.

Area = 225 × 180

⇒ 40500 cm²

Hence "The 1 meter contains 100 centimeters therefore the area of the blanket with dimensions 2.25meters long and 1.8meters wide is 40500 cm²".

melanie has 25.999 ruond to the nearest hunredths?Explain how you found the awnser

Rounding decimals is very similar to rounding other numbers. If the thousandths place of a decimal is four or less, it is dropped and the hundredths place does not change. For example, rounding 0.843 to the nearest hundredth would give 0.84.

If the thousandths place is five through nine, the hundredths place is increased by one. The decimal 0.846 rounded to the nearest hundredth is 0.85.

So for your case 25.999 rounded to the nearest hundredths would be 26.

Final answer:

To round 25.999 to the nearest hundredths, the rounded answer is 26.

Explanation:

To round 25.999 to the nearest hundredths, we need to look at the digit in the thousandths place which is '9'. Since '9' is greater than or equal to 5, we will round up the digit in the hundredths place by adding 1. Therefore, the number 25.999 rounded to the nearest hundredths is 26.

Explain how to check multiplication using addition and division ñ. Include an example in your explanation.

Answers

Addition/Subtraction and. Multiplication/ Division ... So checking one operation with its opposite is a good way to help verify your answer.
Final answer:

Multiplication can be checked using division and addition by following these steps: multiply two numbers, divide the product by one of the numbers used in multiplication (correct multiplication gives the other number), and validate multiplication using repeated addition (adding one of the numbers as many times as the value of the other number).

Explanation:

You can check multiplication using addition and division by following these steps:

Let's take an example of multiplying two numbers, say, 4 and 5, which equals 20. Then, divide the product with one of the multiplier numbers that you used for multiplication. For instance, when you divide 20 (the product of 4 and 5) by 4, you'll get 5. If you get the other number (that you multiplied with at first), then your multiplication was correct. You can also verify multiplication by using repeated addition. In our example, if you add 4 five times: 4 + 4 + 4 + 4 + 4, you'll get 20, which is the same result as the multiplication problem.
