Using the proportional relationship, it is found that:
When x = 1, y = 0.5.When x = 2.5, y = 1.25.When x = 3.5, y = y = 1.75.What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
[tex]y = kx[/tex]
In which k is the constant of proportionality.
In this problem, the relationship is given by:
[tex]y = \frac{x}{2}[/tex]
Hence, when x = 1:
[tex]y = \frac{1}{2} = 0.5[/tex]
When x = 2.5:
[tex]y = \frac{2.5}{2} = 1.25[/tex]
When x = 3.5:

When the numbers 0.04, 0.40, 0.043 are arranged in order, which is the middle number?
Pls be quick
Answer:
0.043
Step-by-step explanation:
arranging in ascending order
0.04,0.043,0.40
or they are 0.040,0.043,0.400
so middle term is 0.043
Given :
the numbers are 0.04, 0.40, 0.043
Arrange the given decimal numbers in ascending order
smallest number is 0.04
So the order of given decimal numbers are
0.04, 0.043 , 0.40
From this we can see that the middle number is 0.043
So, the middle number of the numbers 0.04, 0.40, 0.043 is 0.043

A square park needs grass. Sod is
sold by the square foot. If the park
has a side length of 32.5 feet, how
much sod is needed? HELP ME
Answer:
1056.25 ft**2
Step-by-step explanation:
Square mean length - width so the area is
A = L * W
A = 32.5 * 32.5
A = 1056.25
The sod needed is 1,056.25 square foot .
What is area of a square?The area of a square is the measure of the space or surface occupied by it. It is equal to the product of the length of its two sides. Since the area of a square is the product of its two sides, the unit of the area is given in square units.
Formula of area of square = [tex]side^{2}[/tex]
According to the question
A square park needs grass .
The park has a side length of 32.5 feet
i.e
Side of square = 32.5 feet
Now,
The sod needed = Area of park
By using formula of area of square
= [tex]side^{2}[/tex]
= [tex]32.5^{2}[/tex]
= 1,056.25 square foot

2. US, SV and UV are the midsegments of triangle QRT. If the length of US is 22 cm, what is the length of QT?
The last one says 33cm
Based on the triangle midsegment theorem, the length of QT is calculated as: B. 44 cm.
What is the Triangle Midsegment Theorem?Using the image above as a reference, the triangle midsegment theorem states the length of the midsegment US, of triangle QRT is parallel to the third side, segment QT, and therefore has a length that is half of the length of segment QT.
Given that US is a midsegment in triangle QRT, and it is equal to 22 cm, therefore, we can find the length of the third side it is parallel to, side QT by applying the triangle midsegment theorem as explained below:
The length of US = 1/2(the length of QT)
Substitute
22 = 1/2(QT)
Multiply both sides by 2
2(22) = QT
44 = QT
QT = 44 cm
Therefore, the answer is: B. 44 cm.

[tex]x + 2 \sqrt{x} - 3 = 0[/tex]
Answer:
x = 1
Step-by-step explanation:
Given
x + 2[tex]\sqrt{x}[/tex] - 3 = 0 ( subtract x - 3 from both sides )
2[tex]\sqrt{x}[/tex] = 3 - x ( square both sides )
4x = (3 - x)² ← expand using FOIL
4x = 9 - 6x + x² ( subtract 4x from both sides )
0 = x² - 10x + 9 ← in standard form
0 = (x - 1)(x - 9) ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 9 = 0 ⇒ x = 9
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are solutions.
x = 1 : 1 + 2[tex]\sqrt{1}[/tex] - 3 = 1 + 2 - 3 = 0 → x = 1 is a solution
x = 9 : 9 + 2[tex]\sqrt{9}[/tex] - 3 = 9 + 6 - 3 = 12 ≠ 0
x = 9 is an extraneous solution while x = 1 is a solution

XY = 24
Step-by-step explanation:
In similar triangles, the corresponding sides are in same ratio.
[tex]\frac{AC}{XZ}=\frac{AB}{XY}\\\\\frac{x+6}{30}=\frac{16}{2x-4}[/tex]
Cross multiply,
(x + 6 )(2x-4) = 16*30
Use FOIL method
x*2x + x*(-4) + 6*2x + 6*(-4) = 480
2x² - 4x + 12x - 24 = 480 {Combine like terms}
2x² + 8x - 24 = 480
2x² + 8x - 24 - 480 = 0
2x² + 8x - 504 = 0
Divide the entire equation by 2
x² + 4x - 252 = 0
Sum = 4
Product = -252
Factors = 18 , -14 {18 +(-14) = 4 & 18*(-14) = -254 }
x² + 4x - 252 = 0
x² + 18x - 14x - 252 = 0 {Rewrite middle term}
x(x + 18) - 14(x + 18) = 0
(x + 18)(x - 14) = 0
x - 14 = 0 {Ignore x + 18 = 0 as measurement will not come in negative}
x = 14

Is 2.73234(34 repeating) rational or irrational?
It's rational because of the repeating digits.
We have
x = 2.732343434…
Then
1,000x = 2,732.343434…
and
100,000x = 273,234.343434…
Subtracting these makes the fractional part go away, leaving you with
100,000x - 1,000x = 273,234.343434… - 2,732.343434…
100,000x - 1,000x = 273,234 - 2,732
99,000x = 270,502
x = 270,502/99,000 = 135,251/49,500
which is clearly a rational number.

In the circle below, if < B = 46°, what is the measure of arc AB?
Select one:
a. 23°
b. 46°
c. 92°
d. 112
angle B = ( arc ADB ) ÷ 2
46 = ( arc ADB ) / 2
Multiply both sides by 2
46 × 2 = 2 × ( arc ADB ) / 2
92 = arc ADB
arc AB = arc ADB
arc AB = 92
The measure of arc AB is 92°. Therefore, option B is the correct answer.
Given that, ∠B = 46°.
We need to find the measure of arc AB.
What is an arc of a circle?The arc of a circle is defined as the part or segment of the circumference of a circle. A straight line that could be drawn by connecting the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half of the circle, it is known as a semicircular arc.
Now, ∠B = ( arc ADB ) ÷ 2
46° = ( arc ADB ) / 2
Multiply both sides by 2
46° × 2 = 2 × ( arc ADB ) / 2
92° = arc ADB
arc AB = arc ADB
arc AB = 92°
The measure of arc AB is 92°. Therefore, option B is the correct answer.

34. Which is the rule for the linear
function graphed below?
Answer:
We can note that this part of the graph is a linear function. This means that is has a general form: y = mx + c where m is the slop and c is the y-intercept (value of y at x=0). For the slope, we will use the points (0,2) and (3,5) to calculate it as follows: m = (y2-y1)/(x2-x1) = (5-2)/(3-0) = 1 For the y-intercept, we can note that at x=0, the value of y is 2. This means that the equation of the first part of the graph is: y = x + 2

The graph of the equation
Answer:
Step-by-step explanation:
This equation has a vertical asymptote at x = -2 and a horizontal asymptote at y = 1. This is stuff you should know about rational equations as you learn about them. The vertical asymptote serves as the locked gate or really high wall that the graph cannot go through nor can it go around or over or under. The graph will never cross through the VA. The horizontal asymptote is a horizontal line, y = 1, that reveals the graph's end behavior. So picture this:
We have an x/y coordinate plane. There is a vertical asymptote at x = -2 and a horizontal line at y = 1. This graph, because it cannot go through the vertical asymptote, is "split" into 2 parts, basically. The left "part" comes in along the horizontal asymptote from negative infinity, almost touching it but not quite, and when it reaches x = -2, it drops along the vertical asymptote, almost touching it but not quite and goes down into negative infinity. The right "part" of the graph comes down from positive infinity along the vertical asymptote, almost touching it but not quite, and when it reaches y = 1, it curves along that line off into positive infinity.

the third term and the fifth term of a geometric progression are 2 and 1/8 respectively. If all terms are positive, find the sum to the infinity of the progression
Answer:
42 + 2/3
Step-by-step explanation:
First, to calculate the sum of an infinite geometric series, our formula is
a₁/(1-r), with a₁ being the first term of the series and r being the common ratio. Therefore, we want to find both a₁ and r.
To find r, we can first determine that 2 * r = a₄ and a₄ * r = a₅, as the ratio separates one number from the next in a geometric series. Therefore, we have
2 * r * r = a₅
2 * r² = 1/8
divide both sides by 2 to isolate the r²
r² = 1/16
square root both sides to isolate r
r =± 1/4. Note the ± because r²=1/16 regardless of whether r = 1/4 or -1/4. However, because all terms are positive, r must be positive as well, or a₄, for example, would be 2 * (-1/4) = -0.5
Therefore, r = 1/4 .
To find the first term, we know that a₁ * r = a₂, and a₂ * r = a₃. Therefore, a₁ * r² = a₃ = 2
a₁ * 1/16 = 2
divide both sides by 1/16 to isolate a₁
a₁ = 2 * 1/ (1/16)
= 2 * 16
= 32
Plugging a₁ and r into our infinite geometric series formula, we have
a₁/(1-r)
= 32 / (1-1/4)
= 32/ (3/4)
= 32/ 0.75
= 42 + 2/3
