sometimes, people have a pet house mouse. If a mouse could travel at top speed, running 20.25 miles in 2.5 hours, how far could it travel in an hour
Final answer:
By dividing the total distance (20.25 miles) by the total time (2.5 hours), we find that the mouse has a top speed of 8.1 mph and could therefore travel 8.1 miles in one hour if it maintained this speed.
Explanation:
To find out how far a mouse can travel in an hour at its top speed, we can use the information provided that the mouse ran 20.25 miles in 2.5 hours. This question is essentially asking us to calculate the speed of the mouse in miles per hour (mph), which is a common way to express speed. We'll use a simple division to solve this problem.
First, we divide the total distance traveled by the total time taken to find the speed:
Total Distance = 20.25 milesTotal Time = 2.5 hoursSpeed = Total Distance ÷ Total Time = 20.25 miles ÷ 2.5 hoursPerforming the division:
Speed = 8.1 mph
Therefore, if the mouse continued to run at its top speed, it would be able to travel 8.1 miles in one hour.

A teacher promised a movie day to the class that did better, on average, on their test. The box plot shows the results of the test:
Which class should get the reward, and why?
A. The 2nd period class should get the reward. They have the highest score, a perfect 100.
B. The 2nd period class should get the reward. They have a higher median.
C. The 4th period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd period class.
D. The 4th period class should get the reward. Their lowest score is an outlier, and should be thrown out.
Sarah buys 2 gallons of milk. There are approximately 3.875 liters in a gallon. How many milliliters of milk did Sarah buy?
To calculate the volume in milliliters, we first convert gallons to liters (2 gallons * 3.875 liters/gallon = 7.75 liters), then convert liters to milliliters (7.75 liters * 1000 ml/liter = 7750 milliliters). So, Sarah purchased 7750 milliliters of milk.
Explanation:Sarah purchased 2 gallons of milk, with each gallon approximately 3.875 liters. To convert liters to milliliters (ml), we should remember that 1 liter equals 1000 milliliters. So, to find the total amount in milliliters, we first convert gallons to liters (2 gallons * 3.875 liters/gallon = 7.75 liters), then convert liters to milliliters (7.75 liters * 1000 ml/liter = 7750 milliliters). Therefore, Sarah bought 7750 milliliters of milk.

the ratio of the amount of money Jason had to the amount of money Wilson had was 12:13. After Wilson spent $63, Jason had 3 times as much money as Wilson. How much money did Jason have? How much money did they have altogether in the end?
The ratio of the amount of money Jason had to the amount of money Wilson had was 12:13, then Jason had $12x and Wilson had $13x.
Wilson spent $63, then in the end he had $(13x-63). Since in the end Jason had 3 times as much money as Wilson, then
[tex]\dfrac{12x}{13x-63}=3.[/tex]
Solve it:

A 7-foot tall stop sign creates a shadow that is 2 feet long. At the same time, a utility pole creates a shadow that is 11 feet long. How tall, in feet, is the utility pole?
Answer:
The height of the pole is 38.5 m.
Step-by-step explanation:
Given information:
The height of stop sign is [tex]h=7\rm \; ft[/tex]
Length of shadow of stop sign is [tex]l=2\rm \; ft[/tex].
The length of shadow of pole is [tex]L=11\rm \; ft[/tex].
Now, the shadow is measured at the same time for both the cases. So, the triangles formed by stop sign and its shadow, and pole and its shadow will be similar.
For similar triangles, the sides are always in same proportion.
Solve for the length of pole as,
[tex]\dfrac{H}{h}=\dfrac{L}{l}\\\dfrac{H}{7}=\dfrac{11}{2}\\H=7\times 5.5\\H=38.5[/tex]
Therefore, the height of the pole is 38.5 m.

How is interest similar to sales tax and markups? How is it different?
Interest, sales tax, and markups are all additional charges added to the original amount, but they differ in how they are calculated and when they are charged.
Explanation:Interest is similar to sales tax and markups in that they all involve additional charges or fees that are added to the original amount.
Interest is the extra amount paid for borrowing money, while sales tax is the extra amount paid on the purchase of goods or services, and markups are the extra amount added to the cost price to determine the selling price. They all increase the total cost or price of the transaction.
The main difference is that interest and markups are calculated as a percentage of the original amount, while sales tax is calculated as a percentage of the purchase price. Additionally, interest and markups are typically charged over a period of time or for a specific duration, while sales tax is a one-time charge at the point of sale.

Jeremy’s sister Susie, borrowed money from their mom to pay her order. Their mother has agreed to deduct an equal amount of money from Susie’s allowance each week for the next five weeks to repay the loan. What is the weekly change in Susie’s allowance?
Final answer:
The question requires dividing the total amount borrowed by Susie by the number of weeks to obtain the weekly change in her allowance.
Explanation:
The question pertains to a simple mathematical calculation of equal division of a loan amount across a specified number of weeks to determine the weekly change in Susie's allowance. Although the exact loan amount isn't provided, the process would involve dividing the total sum borrowed by the number of weeks (5 weeks, as mentioned) to find out how much Susie's allowance will reduce each week.
For instance, if Susie borrowed $100, her weekly allowance would be reduced by $100 / 5 = $20 per week.
Final answer:
The weekly change in Susie's allowance is $20.
Explanation:
The weekly change in Susie's allowance can be calculated by dividing the total amount borrowed by the number of weeks she has to repay the loan. In this case, if Susie borrowed $100 and has five weeks to repay it, the weekly change in her allowance would be $100/5 = $20. Therefore, her allowance would decrease by $20 every week for the next five weeks.

What is the distance between points (10,7) and (2,7) on a coordinate plane?
please help me
The distance between points (10,7) and (2,7) on a coordinate plane will be 8 units.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that, the points on the coordinate planes are (10,7) and (2,7).
(x₁,y₁) = (10,7)
(x₂,y₂) = (2,7)
The distance between points (10,7) and (2,7) on a coordinate plane is found as,
(d) = √(x₂ - x₁)² + (y₂-y₁)²
Substitute the given values as,
(d) = √(2 - 10)² + (7 - 7)²
=√(-8)² + (0)²
=√64
=8 units
Thus, the distance between points (10,7) and (2,7) on a coordinate plane will be 8 units.
