A) The six digit number of Hannah is; 513315

B) The number of ways that 15 be written be written as the sum of 4 different counting numbers is; 4 different ways

A) Hannah wants to give a clue about her 6 digit secret number. We are told that if you read the number from right to left, it will be the same number.

Also, the number is a multiple of 9. Lastly, we are told that if we cross off the first and last number, the only remaining prime factor of the remaining four digit number is 11.

From the list of numbers gotten online that fit the bill, the only one that applies in this case is 513315

B) The different ways that 15 can be written as a sum of four different numbers are;

1 + 2 + 3 + 9 = 15

2 + 3 + 4 + 6 = 15

1 + 2 + 5 + 7 = 15

1 + 3 + 4 + 7 = 15

To calculate the amount of punch Jane can make with 6 cups of plum juice, we need to convert cups to liters and use proportions based on the original juice ratios. She can make approximately 4.8 liters of punch with 1.44 liters of plum juice, 2.4 liters of pear juice, and 0.96 liters of pineapple juice.

Jane's favorite fruit punch consists of pear, pineapple, and plum juices in the ratio 5:2:3. To find out how much punch she can make with only 6 cups of plum juice, we need to set up a ratio based on the original proportions. First, we convert the given amount of plum juice to liters because the original recipe is in liters (1 cup is approximately 0.24 liters). Six cups of plum juice is roughly 1.44 liters.

Using the original ratio of 5:2:3 for pear, pineapple, and plum juice, and knowing that the amount of plum juice is 1.44 liters, we can set up the following proportions:

To find the values of x and y, we use cross multiplication:

By solving these equations, we find x (pear juice) is approximately 2.4 liters and y (pineapple juice) is approximately 0.96 liters. Adding these up, Jane can make a total of 4.8 liters of punch with the available plum juice.

Estimation and mental math techniques, like knowing certain reciprocals, help to easily compute numbers mentally, a skill valuable in both academic and real-world settings.

Estimation and mental math are key concepts when considering numbers that are easy to compute mentally. By using heuristics, such as knowing the reciprocals of numbers that multiply to 10, or by rounding numbers to nearest tens or hundreds, we can simplify computations and make them more manageable without the use of calculators or paper. This approach is particularly useful when dealing with real-world scenarios where exact numbers are not necessary and approximate values will suffice.

Step-by-step explanation:

The length of the Mississippi River is approximately 2,336.8 miles.

If the Mississippi River is about [tex]\( \frac{23}{25} \)[/tex] the length of the Missouri River, and the Missouri River is 2,540 miles long, we can find the length of the Mississippi River by multiplying the length of the Missouri River by [tex]\( \frac{23}{25} \).[/tex]

Length of the Mississippi River = [tex]\( \frac{23}{25} \times \text{Length of the Missouri River} \)[/tex]

Substituting the given value for the length of the Missouri River:

Length of the Mississippi River = [tex]\( \frac{23}{25} \times 2540 \)[/tex]

To compute this:

[tex]\[ \frac{23}{25} \times 2540 = \frac{23 \times 2540}{25} \][/tex]

[tex]\[ = \frac{58,420}{25} \][/tex]

= 2,336.8

Therefore, the length of the Mississippi River is approximately 2,336.8 miles.

Therefore, the quotient of 67 divided by 4 is 16.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, 67 divided by 4.

Here,

4|67|16

Final answer:

To estimate the time it would take to fill a swimming pool with a garden hose, use the formula: time = volume / flow rate. Part (a): time = 80,000 L / 60 L/min = 1333.33 min. Part (b): time = 80,000 L / 60,000 L/min = 1.33 min.

Explanation:

To find the time it would take to fill a swimming pool using a garden hose delivering a certain amount of water per minute, you can use the formula: time = volume / flow rate.

For part (a) of the question, the volume of the swimming pool is given as 80,000 L and the flow rate of the garden hose is 60 L/min. Plugging these values into the formula, we get: time = 80,000 L / 60 L/min = 1333.33 min.

For part (b) of the question, the volume of the swimming pool is still 80,000 L, but the flow rate is given in a different unit: 5000 m³/s. To make the units consistent, we need to convert 5000 m³/s to L/min.

There are 1000 L in 1 m³ and 60 min in 1 hour, so the conversion factor is 1000 L / 1 m³ * 60 min / 1 hour = 60,000 L/min.

Plugging this value into the formula, we get: time = 80,000 L / 60,000 L/min = 1.33 min.

After dividing 17 by 4 we get quotient 4 and remainder 1 so the mixed fraction of  [tex]\dfrac{17}{4} = 4 \dfrac{1}{4}[/tex] .

Use the concept of fraction defined as:

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.

Here we have to convert 17/4 into a mixed fraction.

Divide 17 by 4,
