At 12:00 noon two Mississippi steamboats are 126 miles apart. At 6:00 p.m. they pass each other going in opposite directions. If one steamboat travels 9 miles per hour faster than the other, find the speed of both boats.
Final answer:
To determine the speed of two Mississippi steamboats, we use algebra to set up and solve a system of equations. The slower boat travels at 6 miles per hour, and the faster boat travels at 15 miles per hour.
Explanation:
To solve the problem of finding the speed of two Mississippi steamboats, we can set up a system of linear equations. The boats are 126 miles apart and travel towards each other until they pass at 6:00 p.m. This means they've been traveling for 6 hours. Let's define the speed of the slower boat as x miles per hour and the faster boat as x+9 miles per hour.
Since distance equals speed multiplied by time, the distance covered by the slower boat can be represented by 6x and by the faster boat as 6(x+9). The sum of these distances will be equal to 126 miles, the initial distance between the two boats.
Set up the equation: 6x + 6(x + 9) = 126.
Simplify the equation: 12x + 54 = 126.
Solve for x: x = 72 / 12 = 6 miles per hour.
Calculate the speed of the faster boat: x + 9 = 6 + 9 = 15 miles per hour.
Therefore, the speed of the slower steamboat is 6 miles per hour, and the speed of the faster steamboat is 15 miles per hour.

Which of these variables is least likely to have a normal distribution?
a.annual income for all 150 employees at a local high school
b.lengths of 50 newly hatched pythons
c.heights of 100 white pine trees in a forest
d.amount of soda in 60 cups filled by an automated machine at a fast-food restaurant
e.weights of 200 of the same candy bar in a shipment to a local supermarket?
Answer:
Annual income for all 150 employees at a local high school
Step-by-step explanation:
The normal distribution is also called the Gaussian distribution. It is the most common type of distribution for statistical analysis. The normal distribution is based on a probability distribution. The data near the mean are more frequent than the data away from the mean. It is based on two parameters: the mean and the standard deviation.
As per options, option A which states ‘annual income for all 150 employees at a local high school’ the data is within the standard deviation.
Liam bought a picture frame that cost $12 plus 8% sales tax. He wrote the expression 1.08(12) to find his total cost.
Which expression is equivalent to the total cost?
(12+0.08)12
12 + 0.08
1+0.08(12)
(1+0.08)12
The Answer Is D.(1+0.08)12
Hope It Helps Mark Me The Brainlyest PLEASE
The expression which is equivalent to the total cost comprising of the cost of frame and sales tax is (1 + 0.08)12
Given the Parameters :
Cost of frame = $12 Sales tax = 8% = 0.08The total cost can be expressed thus :
Cost of frame = 100% of $12
Sales tax amount = 8% of $12
This can be expressed as :
(100% + 8%) × 12 (1 + 0.08) × 12Therefore, the appropriate expression ls (1 + 0.08)12

[tex]9.6\times 10^-^2[/tex] is 1000 times greater than [tex]9.6\times 10^-^5[/tex]
Explanation
The given numbers are: [tex]9.6\times 10^-^2[/tex] and [tex]9.6\times 10^-^5[/tex]
Dividing the two numbers, we will get.....
[tex]\frac{9.6\times 10^-^2}{9.6\times 10^-^5} = \frac{10^-^2}{10^-^5}= 10^-^2\times 10^5 = 10^3 = 1000[/tex]
As, [tex]\frac{9.6\times 10^-^2}{9.6\times 10^-^5} > 1[/tex]
So, [tex]9.6\times 10^-^2>9.6\times 10^-^5[/tex]
Thus, [tex]9.6\times 10^-^2[/tex] is 1000 times greater than [tex]9.6\times 10^-^5[/tex]

A pet store has 24 Tiger fish and 3 aquariums. Each aquarium has the same number of fish. How many tiger fish are in each aquarium?
Final answer:
To find the number of tiger fish per aquarium, divide the total number of fish (24) by the number of aquariums (3), resulting in 8 tiger fish per aquarium.
Explanation:
The question asks us to determine how many tiger fish are in each aquarium if a pet store has 24 tiger fish and 3 aquariums, with each aquarium having the same number of fish.
To find the answer, we need to divide the total number of tiger fish by the number of aquariums:
Total number of tiger fish = 24
Number of aquariums = 3
We calculate the number of fish per aquarium by performing the division 24 ÷ 3, which equals 8. Therefore, there are 8 tiger fish in each aquarium.

Answer: (1) The correct option is B. (2) he correct option is (C). The correct option is (A).
Explanation:
(1)
In the graphs the x-axis represents the time and the y-axis represents the height.
From given figure 1 it is noticed that the height is consistently increases as the time increases but not in the same proportion.
Because the points are not lies on a single straight line, it means the height increases but not in the same rate.
Therefore, the correct option B.
(2)
From figure 2 it is noticed that at initial state the height decreases after that height increases.
The option 1 represent the increase at constant rate, option 2 represent the increase in height but not at constant rate and option 3 represents the fluctuation in height.
Therefore the correct option is C.
(3)
From figure 3 it is noticed that all the pints lies on a single straight line, therefore the height increases at a constant rate.
So, the correct option is A.
