SOmeOne HelP Me WiTh ThIs QuEsTioN pLz
Step-by-step explanation:
The rate of increase in population is r = 12,600 people/year.
We want to find the rate of change in the population of Austin, Texas in the years between 1980 and 1990.
We will assume that this increase in population is modelled with a linear equation, remember that a general linear equation is y = ax + b.
Where the rate of change, or slope, is a.
What is a slope formula?We know that if a line passes through two points (x₁, y₁) and (x₂, y₂) the slope is given by the formula: m=(y₂-y₁)/(x₂-x₁).
For this case we have two points, these are:
(1980, 346,000)
(1990, 472,000)
Then the slope or rate of change is (472,000-346,000)/(1990-1980)
=12,6000/10
=12,600
Therefore, the rate of increase in population is r = 12,600 people/year.

PLEASE HELP ME ...........Julie was looking at the architect's blueprint of her house. The scale on blueprint was 1/4 inch = 1 foot. On the blueprint, what are the dimensions of her bedroom if the actual dimensions of her bedroom are 12 feet by 16 feet?
Answer:
On the blueprint the dimensions are 48 inches by 64 inches.
Step-by-step explanation:
Given:
The scale on blueprint was 1/4 inch = 1 foot.
The actual dimensions of her bedroom are 12 feet by 16 feet.
Now, to find the dimensions on the blueprint.
Let the dimensions on the blueprint be [tex]x[/tex] by [tex]y.[/tex]
As, given the scale on blueprint:
[tex]\frac{1}{4}\ inch=1\ foot[/tex]
So, [tex]\frac{1}{4}\ inch[/tex] is equivalent to 1 foot.
Thus, [tex]x[/tex] is equivalent to 12 feet.
And, [tex]y[/tex] is equivalent to 16 feet.
Now, solving by cross multiplication method:
[tex]\frac{\frac{1}{4}}{1} = \frac{x}{12}[/tex]
[tex]\frac{4}{1} =\frac{x}{12}[/tex]
By cross multiplying we get:
[tex]48=x[/tex]
[tex]x=48\ inches.[/tex]
Now, again:
[tex]\frac{\frac{1}{4}}{1} =\frac{y}{16}[/tex]
[tex]\frac{4}{1} =\frac{y}{16}[/tex]
By cross multiplying we get:
[tex]64=y[/tex]
[tex]y=64\ inches.[/tex]
Therefore, on the blueprint the dimensions are 48 inches by 64 inches.

The length of a rectangle is 3 1/6 cm longer than the width. The perimeter of the rectangle is 15 1/3 cm. What are the width and length of this rectangle?
Answer:
[tex]Width = 2\frac{1}{4}cm[/tex]
[tex]Length=5\frac{5}{12} cm[/tex]
Step-by-step explanation:
Data from the question;
Perimeter of a rectangle is [tex]15\frac{1}{3}[/tex] cm
Length is [tex]3\frac{1}{6}[/tex] cm longer than the width
We are supposed to determine the length and the with of the rectangle;
Assuming, the width x cm
Then, the length is [tex]x+3\frac{1}{6}[/tex] cm
We need to know that the perimeter of a rectangle is given by;
Perimeter = 2 ( length + width)
Therefore;
[tex]15\frac{1}{3}= 2 ( x + (x+3\frac{1}{6}))[/tex]
[tex]15\frac{1}{3}=2(2x+3\frac{1}{6})[/tex]
Thus;
[tex]15\frac{1}{3}=4x+6\frac{1}{3}[/tex]
[tex]4x=9\\x=2\frac{1}{4}[/tex]
Therefore;
[tex]Width = 2\frac{1}{4}cm[/tex]
[tex]Length = x + 3\frac{1}{6}[/tex]
[tex]=2\frac{1}{4}+3\frac{1}{6}[/tex]
[tex]=5\frac{5}{12} cm[/tex]
Therefore; the length is [tex]5\frac{5}{12}[/tex] cm while the width is [tex]2\frac{1}{4}[/tex] cm

Let f(x) = 2x + 5. The graph of f(x) is transformed into the graph of g(x) by a vertical
stretch of 3 and a translation of 4 units down. What is the equation for g(x)? Show
and explain your work.
The equation of g(x) is g(x) = 6x + 11
Step-by-step explanation:
Let us revise some transformation
A vertical stretching is the stretching of the graph away from the x-axis, If k > 1, the graph of y = k • f(x) is the graph of f(x) vertically stretched by multiplying each of its y-coordinates by kIf the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k∵ f(x) = 2x + 5
∵ The graph of f(x) is stretched vertically by scale factor 3
- That means multiply f(x) by 3
∴ The equation of the new graph is 3(2x + 5)
∵ The new graph is translated 4 units down
- That means subtract 4 from 3(2x + 5)
∴ The equation of g(x) is g(x) = 3(2x + 5) - 4
- Simplify the equation of g(x)
∴ g(x) = 3(2x) + 3(5) - 4
∴ g(x) = 6x + 15 - 4
- Add the like terms in the right hand side
∴ g(x) = 6x + 11
The equation of g(x) is g(x) = 6x + 11

Two sides of a triangle have the same length. The third side measures 4 m less than twice the common length. The perimeter of the triangle is 20 m. What are the lengths of the three sides?
The lengths of the sides of the triangle are 6 m, 6 m, and 8 m.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
Let the length of the first side and 2nd side are x,
Two sides of a triangle have the same length.
The third side measures 4 m less than twice the common length.
So the length of the third side = 2x - 4
Given that the perimeter of a triangle is 20 m
Since the perimeter of a triangle is the addition of the lengths of the triangle's three sides.
So the perimeter of a triangle = sum of all sides
⇒ x + x + 2x - 4 = 20
⇒ 4x = 24
⇒ x = 6
So the length of the third side = 2(6) - 4 = 8
Hence, the lengths of the sides of the triangle are 6 m, 6 m, and 8 m.

#SPJ2
Final answer:
To find the lengths of the triangle's sides, we establish a variable x for the two identical sides. The equation 4x - 4 = 20 is solved to give x = 6. Thus, the triangle has sides of 6 meters, 6 meters, and 8 meters.
Explanation:
The question is asking to determine the lengths of the three sides of a triangle when two of the sides have the same length, and the third side is 4 meters shorter than twice the length of the other two sides. Additionally, it is given that the perimeter of the triangle is 20 meters.
Let's denote the common length of the two sides as x meters. Hence, the length of the third side would be 2x - 4 meters. Since the perimeter of the triangle is the sum of its sides, we have the following equation:
x + x + (2x - 4) = 20
This simplifies to:
4x - 4 = 20
Adding 4 to both sides gives:
4x = 24
Dividing by 4 gives:
x = 6
Therefore, the lengths of the two identical sides of the triangle are 6 meters each, and the length of the third side is 2(6) - 4 = 8 meters.

Find x. For problems 2 and 3
Answer:
x = 4 and x = 7
Step-by-step explanation:
Given that the segment in the triangle is parallel to the third side of the triangle and intersects the 2 sides then it divides these 2 sides in proportion, thus
[tex]\frac{x}{12}[/tex] = [tex]\frac{x+1}{15}[/tex] ( cross- multiply )
15x = 12(x + 1) ← distribute
15x = 12x + 12 ( subtract 12x from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
--------------------------------------------------------------------
[tex]\frac{8}{7}[/tex] = [tex]\frac{16}{2x}[/tex] ( cross- multiply )
16x = 112 ( divide both sides by 16 )
x = 7
Add the two expressions
6q + 1 and q + 11
Addition of 6q + 1 and q + 11 is 7q + 12
Solution:
Given that, we have to add the given two expressions
Given expressions are:
6q + 1 and q + 11
We have to add both the expressions
Addition of 6q + 1 and q + 11 = 6q + 1 + q + 11
Add the coefficients of same variable. Here "q" is present in two terms
Therefore, add 6q and q
Similarly, add the constants 1 and 11
Thus finally addition is done as:
[tex]6q + 1 + q + 11 = 7q +12[/tex]
Thus addition of 6q + 1 and q + 11 is 7q + 12

The GCD and L.C.M of two numbers are 16 and 96 respectively. If the average of
the numbers is 40 then find those numbers.
Answer:
The numbers are 32 , 48
Step-by-step explanation:
Average = 40
Sum of two numbers = 40 * 2 = 80
Let one number =x
Other number = 80 - x
Product of two numbers = GCD * LCM
x*(80-x) = 16*96
80x - x² = 1536
1536 + x² - 80x = 0
x² - 80x + 1536 = 0
x² - 48x - 32x + (-32) * (-48) = 0
x (x -48x) -32 (x -48) =0
(x - 48) ( x - 32) = 0
x - 48 = 0 ; x - 32 = 0
x = 48 ; x = 32
Macy doesn’t have any money in her bank account, but she saves $12.50 each week. Robby has $20 in his bank account, and he saves $7.50 each week. After how many weeks will Macy and Robby have the same amount in their accounts?
After 4 weeks, Macy and Robby will have same amount in their accounts.
Step-by-step explanation:
Given,
Amount saved by Macy each week = $12.50
Let,
x be the number of weeks.
M(x) = 12.50x
Amount saved by Robby each week = $7.50
Amount Robby already have = $20
R(x) = 7.50x + 20
For same amount;
M(x) = R(x)
[tex]12.50x=7.50x+20\\12.50x-7.50x=20\\5x=20[/tex]
Dividing both sides by 5
[tex]\frac{5x}{5}=\frac{20}{5}\\x=4[/tex]
After 4 weeks, Macy and Robby will have same amount in their accounts.

After 4weeks, Macy and Robby will have the same amount in their bank accounts.
To determine after how many weeks Macy and Robby will have the same amount in their bank accounts, we can set up an equation based on their weekly savings and initial amounts.
Let M(t) represent Macy's savings after t weeks, and R(t) represent Robby's savings after t weeks.
Macy's savings can be expressed as:
M(t) = 12.50t
Robby's saving can be expressed as:
R(t) = 20 + 7.50t
We want to find the number of weeks t such that M(t) = R(t)
Setting up the equation:
12.50t = 20 + 7.50t
To solve for t, first subtract 7.50t from both sides:
12.50t - 7.50t = 20
5t = 20
Next, divide both sides by 5 to solve for t
[tex]\[ t = \frac{20}{5} \][/tex]
t = 4
Therefore, after 4weeks, Macy and Robby will have the same amount in their bank accounts.

Ratio is a comparison of two values or two quantities.
Fraction is a another form of ratio.
The first term and the second term in the ratios are important.
It should not be changed.
The first quantity value is in first term and the second quantity value is in second term of the ratio.

There is a 12-ft fence on one side of a rectangular garden. The gardener has 44 ft of fencing to the enclose the other three sides. What is the length of the gardens longer dimension?
Answer:
16 ft
Step-by-step explanation:
One of the other three sides is 12 ft. After that fence is subtracted from the total, there are 32 ft of fence left for the other two sides of the rectangle. That allows those sides to be 32 ft/2 = 16 ft long.
The rectangle can be 12 ft by 16 ft. The longer dimension is 16 ft.
The longer dimension of the rectangular garden is 16 feet. This is found by understanding the perimeter of a rectangle and subtracting the known side from the total fencing available before dividing the result by 2.
Explanation:The subject of this question is Mathematics, specifically related to the area and perimeter of rectangles. To find the length or the longer dimension of the rectangular garden, we need to understand the concept of the perimeter of a rectangle. The perimeter is the sum of all sides of the rectangle. Here, the problem provides us with one side of the rectangle to be 12 feet and the sum of the remaining three sides to be 44 feet.
Considering that the rectangular garden has two equal longer sides and two equal shorter sides, we can say the shorter side is 12 feet. Therefore, the combined length of the other two sides (the longer sides) must be 44-12=32 feet. Because these are equal, each one is 32/2 = 16 feet.
Therefore, the longer dimension of the rectangular garden is 16 feet.
