Answer:
Speed of shuttle in km per hr = 30069.86 km per hr
Speed of shuttle in miles per hr = 18643.31 miles per hr
Step-by-step explanation:
Speed of space shuttle in feet per second= 27,404 feet per second
As
One foot per second = 1.09728 kilometers per hour,
The speed in kilometers per hour is equal to the feet per second multiplied by 1.09728
So
To find out speed of shuttle in km per hour we will mutilpy our speed with 1.09728
27404 ft per sec = 27404x 1.09728 km per hr
speed of shuttle in km per hr = 30069.86 km per hr
Now
As we know 1km = 0.621371 miles
To convert this speed into miles per hr we will multiply our speed with 0.621371
30069.86 km per hr = 30069.86x0.621371 miles per hr
speed of shuttle in miles per hr = 18643.31 miles per hr

On a recent survey, 60% of those surveyed indicated that they preferred walking to running.
a. If 540 people preferred walking, how many people were surveyed?
b. How many people preferred running?
Answer:
a. Number of people surveyed were 900.
b. 360 people preferred running.
Step-by-step explanation:
Given:
On a recent survey, 60% of those surveyed indicated that they preferred walking to running.
If 540 people preferred walking.
Now, to find a. number of people were surveyed. b. number of people preferred running.
a.
Number of people preferred walking = 540.
Percentage of people preferred walking = 60%.
Let the total number of people surveyed be [tex]x.[/tex]
Now, to get the number of people surveyed:
60% of x = 540.
[tex]\frac{60}{100} \times x=540[/tex]
[tex]0.60\times x=540[/tex]
[tex]0.60x=540[/tex]
Dividing both sides by 0.60 we get:
[tex]x=900.[/tex]
Thus, number of people surveyed = 900.
b.
Total number of people surveyed = 900.
People preferred walking = 540.
Now, to get the people preferred running we subtract people preferred walking from total number of people surveyed:
[tex]900-540[/tex]
[tex]=360.[/tex]
Thus, people preferred running = 360.
Therefore, a. Number of people surveyed were 900.
b. 360 people preferred running.
The measure of angle 1 is 30 degrees less than twice the measure of angle 2. What is the measure of angle 1. What is the measure of angle 2
Answer:
110°
Step-by-step explanation:
the supplement of an angle is 30 degrees less than twice the measure of the angle itself. find the angle and its supplement.
Let the angle be A, then its supplement = (180 - A)
Now, since the supplement is 30 degrees less than twice the measure of the angle itself, then we'll have:
180 - A = 2A - 30
-3A = - 210
A, or the angle = [tex]\frac{-210}{-3}[/tex]= 70 °
Its supplement, (180 - A) = 180 - 70 = 110°
Collin has $500 in his bank account. He starts saving $30.00 per week. Kamryn
has $750 in her bank account, and she is saving $20.00 per week. Assume
neither Collin nor Kamryn make any withdrawals.
After how many weeks will. Collin and Kamryn have the same amount of
money in their accounts?
Answer:
x = 25
Step-by-step explanation:
You would need to start by creating an equation. X would represent the numbers of weeks.
500 + 30x = 750 + 20x
Now get the numbers on one side. To do this subtract 500 form each side.
30x = 250 + 20x
Next, get the variables to one side. This can be done by subtracting 20x from each side.
10x = 250
Finally divide by 10 to get the variable by its self.
x = 25
Hope this helps.
After 25 weeks, Collin and Kamryn have the same amount of
money in their accounts.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the after x weeks, Collin and Kamryn have the same amount of money in their accounts:
Then we can frame a linear equation as per the problem:
Collin's amount of money = 500 + 30x
Kamryn amount of money = 750 + 20x
500 + 30x = 750 + 20x
10x = 250
x = 25
Thus, after 25 weeks Collin and Kamryn have the same amount of
money in their accounts.

A company provides bus trips to various events for a adults and c children. The company charges $18 for each adult and $8 for each child for a trip to an upcoming play. The bus has a maximum capacity of 40 people and the school can only spend $400 dollars on the trip. Write and solve a system of equations to determine the maximum number of adults and children that can attend the play that will satisfy these constraints.
Final answer:
To determine the maximum number of adults and children that can attend the play without exceeding the bus capacity of 40 people and the $400 budget, set up and solve a system of equations representing the capacity and budget constraints. The solution is 8 adults and 32 children.
Explanation:
We are given a situation where a company charges $18 for each adult (a) and $8 for each child (c) for a bus trip to an upcoming play, with the constraints that the bus holds a maximum of 40 people and the available budget is $400. To find the maximum number of adults and children that can attend under these constraints, we need to set up a system of equations:
For the capacity constraint: a + c = 40
For the budget constraint: 18a + 8c = 400
We can solve this system using substitution or elimination. Let's use elimination. Multiply the first equation by -8 and add it to the second equation to eliminate c:
-8a - 8c = -320
18a + 8c = 400
Adding these two equations together gives us:
10a = 80
Thus, a = 8. Plugging a = 8 back into the first equation, we get c = 32.
The maximum number of adults and children that can attend the play is 8 adults and 32 children.

Ben’s living room is a rectangle measuring 10 yards x 168” by how many feet does the legs of the room exceed the width
Answer:
16 feet.
Step-by-step explanation:
Given:
Ben’s living room is a rectangle measuring 10 yards x 168.
Question asked:
How many feet does the legs of the room exceed the width ?
Solution:
By applying unitary method:
Length of rectangle = 10 yards = 30 feet (1 yard = 3 feet)
(10 yard = [tex]3\times10 = 30)[/tex]
Breadth of rectangle = 168 inch = 14 feet (12 inch = 1 feet)
(1 inch = [tex]\frac{1}{12}[/tex])
( 168 inch = [tex]\frac{1}{12}[/tex][tex]\times168 = 14 feet)[/tex]
By subtracting the breadth from the length of rectangle,
30 feet - 14 feet = 16 feet
Therefore, by 16 feet, length of the room exceed the width.

It's usual that students make mistakes when misunderstanding the application of algebra's basic rules. Here we have two of them
When we change the signs of all the terms of a polynomial, the expression must be preceded by a negative sign When multiplying negative and positive quantities, if the number of negatives is odd, the result is negative. If the number of negatives is even, the result is positive. Not to confuse product of fractions with the sum of fractions. Rules are quite different
The first expression is
[tex]1-x / (5-x)(-x)=x-1 / x(x-5)[/tex]
Let's arrange into format:
[tex]\displaystyle \frac{1-x}{(5-x)(-x)} =\frac{x-1 }{ x(x-5)}[/tex]
We can clearly see in all of the factors in the expression the signs were changed correctly, but the result should have been preceeded with a negative sign, because it makes 3 (odd number) negatives, resulting in a negative expression. The correct form is
[tex]\displaystyle \frac{1-x}{(5-x)(-x)} =-\frac{x-1 }{ x(x-5)}[/tex]
Now for the second expression
[tex]5/s+2/5=2/s[/tex]
Let's arrange into format
[tex]\displaystyle \frac{5}{s}+\frac{2}{5} =\frac{2}{s}[/tex]
It's a clear mistake because it was asssumed a product of fractions instead of a SUM of fractions. If the result was correct, then the expression should have been
[tex]\displaystyle \frac{5}{s}\times \frac{2}{5} =\frac{2}{s}[/tex]

Madison went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 500 mg of sodium and each frozen dinner has 700 mg of sodium. Madison purchased 2 more frozen dinners than cans of soup and they all collectively contain 7400 mg of sodium. Determine the number of cans of soup purchased and the number of frozen dinners purchased.
Madison purchased 5 cans of soup and 7 frozen dinners.
Step-by-step explanation:
Given,
Quantity of sodium in each soup can = 500 mg
Quantity of sodium in each frozen dinner = 700 mg
Total quantity = 7400
Let,
Number of soup cans purchased = x
Number of frozen dinners purchased = y
According to given statement;
500x+700y=7400 Eqn 1
y = x+2 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
[tex]500x+700(x+2)=7400\\500x+700x+1400=7400\\1200x=7400-1400\\1200x=6000[/tex]
Dividing both sides by 1200
[tex]\frac{1200x}{1200}=\frac{6000}{1200}\\x=5[/tex]

Marcos had 15 coins in nickels and quarters. He had 3 more quarters than nickels. He wrote a system of equations to represent this situation, letting x represent the number of nickels and y represent the number of quarters. What is the solution?
Answer:
Marcos had 6 nickel coins and 9 quarter coins.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of nickel coins and y be the number of quarter coins.
Marcos had 15 coins in nickels and quarters.
Thus, we can write the equation:
[tex]x + y =15[/tex]
He had 3 more quarters than nickels. We can write he equation,
[tex]y = x + 3[/tex]
Solving the two equations, we get,
[tex]2y = 18\\y = 9\\x + 9 = 15\\x = 6[/tex]
Thus, Marcos had 6 nickel coins and 9 quarter coins.
The solution to the system of equations representing Marcos's coins is x = 6 and y = 9. Hence, Marcos had 6 nickels and 9 quarters.
Explanation:This question pertains to creating and solving a system of equations in mathematics. Given Marcos had 15 coins in nickels and quarters and considering the information that he had 3 more quarters than nickels, two equations can be formed from this. The first equation sets up the total number of coins: x + y = 15. The second equation sets ups the difference in quantity of each coin: y = x + 3.
To find the solution, substitute the second equation in for y in the first equation. This gives: x + (x + 3) = 15. Solve the equation and find x = 6. Furthermore, using x in our second equation, we get y = 6 + 3 = 9. Therefore, Marcos had 6 nickels and 9 quarters.

what does x equal in the function: f(-11)=5x+1
Final answer:
In the equation f(-11)=5x+1, solving for x yields x = -2.4.
Explanation:
To find what x equals in the function f(-11)=5x+1, we start by understanding that the function f(x) identifies the relation between x and f(x). In this case, f(-11) has been given the value of 5x+1. Therefore, we solve for x by setting the expression equal to f(-11).
We have the equation 5x + 1 = f(-11). Since f(-11) is given as a constant, we substitute and solve for x:
5x = -12
x = -2.4
Hence, x equals -2.4 in the function f(-11)=5x+1.
