Write an expression for the perimeter of the triangle shown below: (4 points)
A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.
6.9x − 16
6.9x + 16
0.1x − 16
0.1x + 16
Answer:
The correct option is 3.
Step-by-step explanation:
It is given that the length of sides of a triangle are 0.5x+9, 3x, and -3.4x-25.
Let a=0.5x+9, b=3x, and c=-3.4x-25.
Perimeter of a triangle is the sum of length of all three sides.
[tex]Perimeter=a+b+c[/tex]
Substitute a=0.5x+9, b=3x, and c=-3.4x-25 in the above equation.
[tex]Perimeter=(0.5x+9)+(3x)+(-3.4x-25)[/tex]
On simplification, we get
[tex]Perimeter=0.5x+9+3x-3.4x-25[/tex]
Combine like terms.
[tex]Perimeter=(0.5x+3x-3.4x)+(9-25)[/tex]
[tex]Perimeter=(0.1x)+(-16)[/tex]
[tex]Perimeter=0.1x-16[/tex]
Perimeter of the triangle is 0.1x-16. Therefore the correct option is 3.

the walls of a square room need painting.Each of the four walls is 12 ft wide by 8.5 feet tall.One gallon of paint covers 75 ft.How many gallons will you need?
The walls of a room need painting. Each of the four walls is 12 ft wide by 8.5 feet tall.
We know that, Area = length [tex]\times[/tex] width.
So, the area of one wall = 8.5 ft [tex]\times[/tex] 12 ft = 102 square feet
Thus, the area of 4 walls = 4 [tex]\times[/tex] 102 = 408 square feet
One gallon of paint covers 75 square feet. We need to find how many gallons of paint will cover 408 square feet.
So, the amount of gallons of paint needed = 408[tex]\div[/tex]75
= 5.44 gallons
So, 5.44 gallons are needed to cover 408 square feet.
To find the number of gallons of paint needed to paint the walls of a square room, calculate the total area of all four walls and divide it by the coverage of one gallon of paint.
Explanation:To find the total area of all four walls, we need to calculate the area of one wall and then multiply it by four. The area of one wall is the product of its width and height, which is 12 ft x 8.5 ft = 102 ft².
So, the total area of all four walls is 102 ft² x 4 = 408 ft².
Since one gallon of paint covers 75 ft², we divide the total area of all four walls (408 ft²) by the coverage of one gallon of paint (75 ft²) to find the number of gallons needed: 408 ft² ÷ 75 ft² = 5.44 gallons.
Therefore, you will need approximately 5.44 gallons of paint to paint the walls of the square room.

simplify the expression by combining like terms.
7b + 4 - 3b - 2
what the number that goes n the box ?
( ? ) b + ( ? )
Final answer:
Combine like terms by adding or subtracting the coefficients of terms with the same variable and combining constants. The simplified expression is 4b + 2, so the coefficients that go in the boxes are 4 and 2.
Explanation:
To simplify the expression by combining like terms, follow the process of identifying and adding/subtracting like terms. The expression 7b + 4 - 3b - 2 contains both variable terms (containing 'b') and constant terms (just numbers).
Combine like terms:
Combine variable terms: 7b - 3b = 4b.
Combine constant terms: 4 - 2 = 2.
After combining like terms, the simplified expression is 4b + 2.
Therefore, the numbers that go in the boxes are 4 for the coefficient of 'b' and 2 for the constant term.

A business owner pays $1,200 per month in rent and a total of $120 per hour in employee salary for each hour the store is open. On average, the store brings in $200 in net sales per hour. Which equation can be solved to determine the break-even point if x represents the number of hours per month the store is open?
The break-even point can be determined by setting the net sales per hour equal to the total cost per hour. The equation to solve for the break-even point is $200x = $1,320x. By dividing both sides of the equation by $1,320, we can find the value of x, which represents the number of hours per month the store needs to be open to break even.
Explanation:To determine the break-even point, we need to find the number of hours per month the store needs to be open in order to cover all its costs. The total cost for each hour the store is open is the sum of the rent and the employee salary. So, the total cost per hour is $1,200 + $120 = $1,320. The break-even point is reached when the net sales per hour equals the total cost per hour:
Net sales per hour = Total cost per hour
In this case, the net sales per hour is $200, so we can set up the equation:
$200x = $1,320x
where x represents the number of hours per month the store is open. By dividing both sides of the equation by $1,320, we can solve for x:
$200 = $1,320x / $1,320
$200 / $1,320 = x
x = 0.1515...
So, the break-even point is approximately 0.1515... hours per month, or about 9.09 minutes per month.

Violet is watching the sand in a hourglass drain from the upper portion to the lower portion of the glass. She wonders how fast the sand is draining.
Which unit rates would be reasonable for Violet to use to describe how fast the sand is draining from the upper portion to the lower portion of the glass?
Select EACH correct answer.
gallons per hour
liters per hour
cubic centimeters per minute
cubic inches per second
The unit rates which will be reasonable for Violet to use to describe how fast the sand is draining from the upper portion to the lower portion of the glass is cubic centimeters per minute.
Explanation:
As the first 2 options gallons per hour and liters per hour, these denote liquid forms. But sand is not liquid that is why it cannot be the answer.
Cubic inches per second is very fast as compared to the small hourglass and the amount of sand that could be present in it. Moreover one side of the hourglass needs to be emptied in 24 hours, so this option is also not possible.

At 9:00 am linda leave work on a trip, sets her cruise control at 60mph. At 9:30 am, Bruce notices she left her briefcase and gets on the free way driving 90mph. At what time will Bruce catch up with Linda?
Bruce will catch up with Linda at 9:48 am.
Explanation:To find the time at which Bruce catches up with Linda, we need to determine the time it takes for Bruce to cover the same distance that Linda has already covered.
Since Linda starts her trip at 9:00 am and Bruce starts 30 minutes later at 9:30 am, Linda has a head start of 30 minutes or 0.5 hours.
In that 0.5 hours, Linda travels a distance of:
Distance traveled by Linda = Speed * Time
Distance traveled by Linda = 60 mph * 0.5 hours
Distance traveled by Linda = 30 miles
Now, Bruce needs to catch up with that distance of 30 miles. Let's find the time it takes for Bruce to cover that distance at his speed of 90 mph:
Time taken by Bruce = Distance / Speed
Time taken by Bruce = 30 miles / 90 mph
Time taken by Bruce = 0.33 hours
Since Bruce started at 9:30 am, he will catch up with Linda at:
Catch up time = Start time + Time taken by Bruce
Catch up time = 9:30 am + 0.33 hours
Catch up time = 9:48 am

The graph below represents the function f(x), and the table below represents the function g(x).
Which statement is true?
The maximum value of g(x) is greater than the minimum value of f(x).
The minimum value of g(x) is less than the maximum value of f(x).
The minimum value of g(x) is greater than the maximum value of f(x).
The maximum value of g(x) is less than the minimum value of f(x).
Thank you! :)
The statement that is true about the graph is The maximum value of g(x) is greater than the minimum value of f(x).
1. "The maximum value of g(x) is greater than the minimum value of f(x)": This is true because the maximum value of g(x) is -10, which is greater than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).
2. "The minimum value of g(x) is less than the maximum value of f(x)": This is true based on the given data, as the minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know, but it cannot be higher than -1 based on the given data).
3. "The minimum value of g(x) is greater than the maximum value of f(x)": This is false based on the given data. The minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know).
4. "The maximum value of g(x) is less than the minimum value of f(x)": This is false based on the given data. The maximum value of g(x) is -10, which is less than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).
The greatest value of g(x) is -1 (the higher number for the g(x) entry in the table), and the minimum value of f(x) is -3 (the lower y/f(x) you may point on the graph). As a result, the maximum value of g(x) exceeds the minimum value of f(x).
