A race car travels at a speed of 230 miles per hour. The race track on which the car is competing is 400 miles long. About how long does it take for the car to finish, disregarding pit stops and yellow flags?
A) 174 minutes
B) 345 minutes
C) 1 hour 45 minutes
D) 2 hours 14 minutes

Answers

Answer 1
To solve for this we will be using the formula S = D/T

S = Speed
D = Distance 
T = Time

First we need to re-arrange this formula to solve for time

T= D/S

T = 400/230

T=1.74 hours

.74 hours is close enough to .75 that we can say it is 45 minutes

So it is 1 hour and 45 minutes
Answer 2

Answer:

Option(c)

Step-by-step explanation:

The race track on which the car is competing miles= 400 miles

A car travels with speed= 230 miles per hour

We have to find time taken for the car to finish

As we know,

Time taken to cover certain distance=[tex]\frac{Distance}{Time}[/tex]

Time taken to cover certain distance=[tex]\frac{400}{230}[/tex]

Time taken to cover certain distance=[tex]\frac{40}{23}[/tex]

Time taken to cover certain distance=1 hour 45 minutes

Hence, the correct answer is option(c)

Jane’s favorite fruit punch consists of pear, pineapple, and plum juices in the ratio 5:2:3.
How much of each juice is needed to make 25 liters of this punch?
I got 12.5L for pear, 5L for pineapple, and 7.5L for plum. These were all right. Now, I have the second part I need help with:

How much punch can she make if she has only 6 cups of plum juice?

Answers

Answer:

20!

Step-by-step explanation:

trust me i just did this problem! is 20 :)

Final answer:

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.

Explanation:

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:

Plum Juice: 3 parts (original ratio) = 1.44 liters (actual)Pear Juice: 5 parts (original ratio) = x liters (actual)Pineapple Juice: 2 parts (original ratio) = y liters (actual)

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

For pear juice: (5/3) = x/1.44For pineapple juice: (2/3) = y/1.44

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.

Estimate the quotient of 67 divided by 4

Answers

Of course! 
So basically division is finding out how many times a number goes into the other number. In this case we are trying to see how many times 4 goes into 67. 
4 goes into 67 16.75 times. 
Since we are estimating the answer is a little different. 
If we are rounding the the nearest tenth the answer would be 16.8. 
If you are round the the nearest whole number the answer is 17. 

I hope this helps!

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

What is the division?

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.

The Mississippi River is the second longest river in the United States,second only to the Missouri River. The Mississippi River is about 23/25 the length of the Missouri River.if the Missouri River is 2,540 miles long,how long is the Mississippi River?

Answers

Well the percent of 23 into 25 is 92%, so 92% of 2,540 is 2,336.8.

So I believe the answer is 2336.8.

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.

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.

Explanation:

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.

How to find a six digit number?

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

A 18,000 gallon swimming pool contains 7,000 gallons of water when a hose is placed into the pool and begins adding water at a rate Of 1100 gallons per hour

Answers

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.
