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.

Step-by-step explanation:
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.

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.

PLEASE HELP, BRAINLIEST William pays $32 per year for no-deductible comprehensive coverage of his new full sized car. A hailstorm causes $250 worth of damage to the paint on his car
How much will the insurance pay?
How much must Richard pay?
Answer:
The insurance company will pay $250.
Step-by-step explanation:
Deductible is the amount of the loss a policy holder pays when he files for an insurance claim, before the insurance company pays any money. And no deductible means that the person will not pay anything, The insurance company will pay.
So, here William pays for a no deductible insurance, which means he will not pay anything. His insurance company will pay the total amount of $250.

What is the relationship between 9.6×10^−2 and 9.6×10^−5 ? Select from the drop-down menus to correctly complete the statement. 9.6×10−2 is ? times ? than 9.6×10−5 .
[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.

Whats the answer for solve the equation 6x + 3y = 15 for y. what does y equal if x = 2? if x = 5?
To solve the linear equation 6x + 3y = 15 for y, isolate y, which yields y = (15 - 6x) / 3. Substituting x as 2, we find y = 1, and when x is 5, y equals -5.
In order to solve the equation 6x + 3y = 15 for y, we must first isolate y on one side of the equation. This can be done by first subtracting 6x from both sides of the equation, resulting in 3y = 15 - 6x. To solve for y, we then divide both sides by 3, obtaining y = (15 - 6x) / 3.
When x = 2, we substitute it into the equation to find y:
y = (15 - 6(2)) / 3y = (15 - 12) / 3y = 3 / 3y = 1.
Similarly, when x = 5, we find y by substitution:
y = (15 - 6(5)) / 3y = (15 - 30) / 3y = -15 / 3y = -5.

graph the linear equation. find three points that solve the equation, then plot on the graph -5x+2y=11
To graph the linear equation -5x+2y=11, choose x values and solve for y to find points for plotting. Three example points are x = 0, 2, and -5 with y values of 11/2, 8, and 21 respectively.
Explanation:Graphing the Linear Equation -5x + 2y = 11:
To find points, we can choose values for x and then solve for y.Choose x = 0, x = 2, x = -5 as examples.For x = 0, y = 11/2; for x = 2, y = 8; for x = -5, y = 21. Plot these points on a graph and draw a straight line through them.A manufacturer is producing two types of shoes, types A and B. Type A cost $4 to produce and takes one hour.
