Answer:
1350
Step-by-step explanation:
I added tower A and B together (90+180) Which gives me 270. Then I did;
270 * 5= 1350 ft. Hope its correct!
Final answer:
Tower C is 5 times as tall as the combined height of Tower A (90 feet) and Tower B (180 feet), which together are 270 feet tall. Multiplying this by 5 gives us the height of Tower C, which is 1350 feet.
Explanation:
The question asks us to calculate the height of Tower C given the heights of Tower A and Tower B and the relationship between their heights. Tower A is 90 feet tall, and Tower B is 180 feet tall. According to the question, Tower C is 5 times as tall as both Towers A and B combined.
To find the combined height of Towers A and B, we simply add their heights:
Tower A height: 90 feetTower B height: 180 feetCombined height of Tower A and B: 90 + 180 = 270 feetNow, we need to calculate the height of Tower C:
Height of Tower C = 5 × (Height of Tower A + Height of Tower B)Height of Tower C = 5 × 270 feetHeight of Tower C = 1350 feetTherefore, Tower C is 1350 feet tall.

Mr. Torres spent $30.00 to buy 9/1/2 pounds of ground beef and chicken for a family cookout. If the price of ground beef was $4.50 per pound and chicken was $3.00 per pound, how many pounds of each did he buy?
Answer:
Therefore Mr. Torres buys 1 pound of ground beef and 8.5 pounds of chicken.
Step-by-step explanation:
i) Let x be the number of pounds of ground beef
ii) Let y be the number of pounds of chicken.
iii) therefore x + y = 9.5 pounds
iv) also we have 4.5 x + 3 y = 30 dollars
v) multiplying the equation in iii) by 3 we get 3x + 3y = 28.5
vi) Subtracting the equation in v) from the equation in iv) we get 1.5 x = 1.5
vii) Therefore x = 1 pound
viii) substituting the value of x in vii) in the equation in iii) we get
1 + y = 9.5 . Therefore y = 8.5 pounds.
ix) Therefore Mr. Torres buys 1 pound of ground beef and 8.5 pounds of chicken.

Simplify 3(2x-8)-11x
The expression 3(2x-8)-11x simplifies to -5x - 24 by distributing the 3 and then combining like terms.
To simplify the expression 3(2x-8)-11x, we must first distribute the 3 to both terms within the parenthesis and then combine like terms. Here's the step-by-step process:
Multiply 3 by 2x to get 6x.
Multiply 3 by -8 to get -24.
Combine the products from steps 1 and 2 with the -11x.
So, 3(2x-8) equates to 6x-24.
Now, combine 6x - 24 with -11x (6x-24-11x).
Simplify the like terms by subtracting 11x from 6x which gives -5x.
Our final expression is -5x - 24.
Therefore, the simplified expression of 3(2x-8)-11x is -5x - 24.

Answer:
90°
Step-by-step explanation:
All circles are equal to 360°. Since the pie chart is a circle, if you added all of the central angles for all three sections, it would total to 360°.
Since the circle is not divided into 360 parts for each degree, but 100 parts for each percent %.
You can solve using an equivalent. Write each fraction in the form "Lemonade" over "total". The left side is percentage, the right side is degrees.
Let x be the central angle for lemonade
[tex]\frac{25}{100}=\frac{x}{360}[/tex]
Solve for the central angle of lemonade by isolating 'x'. To isolate x, move 360 over to the other side. When moving numbers in an equivalent, you do the opposite operation to both sides. Since 'x' divides by 360, multiply 360 on both sides.
[tex]\frac{25}{100}=\frac{x}{360}[/tex]
[tex]360*\frac{25}{100}=360*\frac{x}{360}[/tex] 360 cancels out on the right
[tex]\frac{360*25}{100}=x[/tex] Combined multiplication in numerator
[tex]\frac{9000}{100}=x[/tex] When dividing, 0s cancel out
[tex]\frac{90}{1}=x[/tex] Simplify fraction over 1
[tex]x = 90[/tex] Answer
Therefore the central angle in the Lemonade section is 90°.

The perimeter of a rectangle is 34 units. Its width is 6.5 point, 5 units.
The perimeter of a rectangle is 34 units. Its width W is 6.5 units.
Write an equation to represent the perimeter in terms of the length L, and find the value of L
Answer:The length of rectangle is 10.5 units
Solution:Given that,
Perimeter of rectangle = 34 units
Width of rectangle = 6.5 units
Let "L" be the length of rectangle
The perimeter of rectangle is given by formula:
Perimeter = 2(length + width)
Substituting the values we get,
[tex]34 = 2(L + 6.5)[/tex]
Thus the equation is found
Solve for "L"
[tex]L + 6.5 = \frac{34}{2}\\\\L + 6.5 = 17\\\\L = 17 - 6.5\\\\L =10.5[/tex]
Thus length of rectangle is 10.5 units
What is the inverse of the fuction f(x)= x+3
Answer:
Inverse of function f(x) is y =x-3
Step-by-step explanation:
Given:
f(x) = (x+3)
To Find:
Inverse of f(x)
Solution:
Inverse of the function:
Let f: X -> Y be a function with domain X and target set Y. Then g is the inverse of f if g is a function with domain Y and target set X such that
g(f(x)) = x for all x in X
f(g(y)) = y for all y in Y.
f has an inverse function if and only if f is both one-to-one and onto. If f is one-to-one and onto, then its inverse function g is defined implicitly by the relation g(f(x)) = x.
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
Let y = f(x) = x+3
So, swapping the variables: y=x+3 becomes x=y+3
Now, solve the equation x=y+3 for y.
y=x−3
y=x−3

Solve the inequality 2n -3 ≥ 5 and graph the solutions
Answer: n ≥ 4
Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation which is to get x by itself on one side of the inequality.
Since 3 is being subtracted from 2n, add 3 to both sides of the inequality to get 2n ≥ 8. Now since n is being multiplied by 2, we need to divide by 2 on both sides of the inequality to get n ≥ 4.
Our next task is to graph n ≥ 4 on a number line and to do that, we start with a closed dot at 4. The reason we use a closed dot at 4 is because not only is n greater than 4 but it's also equal to 4. Next we draw an arrow going to the right on our number line to represent all numbers greater than 4.
When graphed, it should look something like the image attached.

equation two: -x + 2y = 13
A. Multiply equation 1 by 2 and equation two by 3. Then add the new equations.
B. Multiply the left side of equation 2 by 2. Then subtract the result from equation 1.
C. Multiply equation 2 by -2. Then add the result to equation 1.
Answer:
B
Step-by-step explanation:
The Elimination Method is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.
If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.When multoplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).
So, option B is not allowed (it is not allowed to multiply only one part of equation)

Julia planet a rectangle garden that is 20 feet long she plays 56 feet of fencing around her Garten what is the width of her Garten what is the area
The width of rectangular garden(b) = 8 feet and
The area of rectangular garden = 160 square feet
Step-by-step explanation:
Given,
The length of rectangular garden(l) = 20 feet and
The perimeter of rectangular garden(fencing) = 56 feet
To find, the width of rectangular garden(b) = ? and
The area of rectangular garden = ?
We know that,
The area of rectangular garden = 2(l + b)
⇒ 2(20 + b) = 56
⇒ 20 + b = 28
⇒ b = 28 - 20 = 8 feet
The width of rectangular garden(b) = 8 feet
∴ The area of rectangular garden = l × b
= 20 feet × 8 feet
= 160 square feet
Hence, the width of rectangular garden(b) = 8 feet and
the area of rectangular garden = 160 square feet
The width of Julia's garden is 8 feet, and the area of her garden is 160 square feet. The calculations were made using the perimeter and area formulas for rectangles.
To find the width of Julia's rectangular garden and its area, we can use the given information:
The garden is 20 feet long, and the total perimeter of the garden is 56 feet.
Step-by-Step Solution:
The formula for the perimeter P of a rectangle is given by:
P = 2L + 2W
where L is the length and W is the width.
We know the following values:
L = 20 feet
P = 56 feet
Substitute these values into the perimeter formula:
56 = 2(20) + 2W
Simplify and solve for W:
56 = 40 + 2W
56 - 40 = 2W
16 = 2W
W = 8 feet
Now we can find the area A of the garden using the formula for the area of a rectangle:
A = L × W
Substitute the values we have:
A = 20 × 8
A = 160 square feet
The width of Julia's garden is 8 feet, and the area of her garden is 160 square feet.

#2. subtract by 1.5 on both sides
#3. 3x=2.5x +3.2
#4. then subtract 2.5x on both sides because you need all the x'x on one side
#5. .5x= 3.2

#7. x=6.4
The equation 3x + 1.5 = 2.5x + 4.7 has one solution which is x = 6.4.
Explanation:The equation at hand is 3x + 1.5 = 2.5x + 4.7. To check whether the equation has no solution, one solution, or an infinite number of solutions, we have to solve the equation.
By collecting like terms, 3x - 2.5x = 4.7 - 1.5 will give us 0.5x = 3.2. To isolate x, we simply divide both sides of the equation by 0.5, leading to x = 3.2/0.5 which equals 6.4.
