Her son washed the most laundry.
The number of laundries that need to be washed is 46.5%.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
The number of laundries Mr. Barnes washed = 2/7.
This means,
= 2/7 x 100
= 28.5%
The number of laundries her son washed = 1/4.
This means,
= 1/4 x 100
= 25%
We see that,
Her son washed the most laundry.
The number of laundry needs to be washed.
= 100% - (28.5% + 25%)
= 100% - 53.5%
= 46.5%
Thus,
Her son washed the most laundry.
The number of laundries that need to be washed is 46.5%.

A forest covers 68,000 acres. A survey finds that 0.8% of the forest is old-growth trees. How many acres of old-growth trees are there?
Answer:
544 acres
Step-by-step explanation:
There is 100% in a whole.
1% is 1/100th of the whole, or 0.01 of it. We get this because 1/100 = 1/100 = 0.01
Similarly, 0.8/100 = 0.008. We then multiply the decimal by the total to get
(0.008) ( 68000) = 544 acres

[tex]Ratio = 1.5 : 1[/tex]
Step-by-step explanation:
Given
[tex]Ratio = 6 : 4[/tex]
Required
Express as [tex]n : 1[/tex]
[tex]Ratio = 6 : 4[/tex]
Divide ratio by 4
[tex]Ratio = 6/4 : 4/4[/tex]
[tex]Ratio = 6/4 : 1[/tex]
Express 6/4 as 1.5
[tex]Ratio = 1.5 : 1[/tex]

What expression can you substitute for y in
this equation?
-4y + x = -27
Enter the correct answer.
Answer:
1/4x+27/4
Step-by-step explanation:
Here's the equation: -4y+x=-27
We'll need to isolate y on one side
subtract x from both sides
-4y=-x-27
divide everything by -4
y=1/4x+27/4
So you can substitute 1/4x+27/4 for y.
hope this helps!

Answer:
B
Step-by-step explanation:
The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 11 and 55. The y-intercept of f(x)f(x) is 2020. Write the equation of the quadratic polynomial in standard form.
Answer: [tex]4x^2 -24x+20[/tex]
Step-by-step explanation:
If p and q are zeroes of f(x), then f(x) = k (x-p)(x-q) , where k is a constant.
Given: The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 1 and 5.
f(x) = k (x-1)(x-5)
y-intercept = Value of function at x=0
So, y-intercept = k (0-1)(0-5)= 5k
Since, y-intercept of f(x) = 20
so, 5k = 20
⇒ k= 4
Quadratic polynomial [tex]= 4(x-1)(x-5)[/tex]
[tex]=4(x^2-6x+5)\\\\= 4x^2 -24x+20[/tex]
Hence, the equation of the quadratic polynomial in standard form =[tex]4x^2 -24x+20[/tex]

An architect draws a plan for a wheelchair ramp on the plan, the ramp is 2cm high and 24cm long what might the dimensions of the actual ramp be (use equivalent ratios)
Answer:
[tex]Height = 30cm[/tex]
[tex]Length = 360cm[/tex]
Step-by-step explanation:
Given
Scale Measurement
[tex]Height = 2cm[/tex]
[tex]Length = 24cm[/tex]
Required
Determine the possible actual measurement
First, calculate the equivalent ratio.
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{24cm}{2cm}[/tex]
[tex]Ratio = 12[/tex]
To do this, we pick a scale factor.
Assume the scale factor is 15.
The actual measurement will be:
[tex]Height = 2cm * 15[/tex]
[tex]Height = 30cm[/tex]
[tex]Length = 24cm * 15[/tex]
[tex]Length = 360cm[/tex]
When the scale ratio is calculated, we have:
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{360cm}{30cm}[/tex]
[tex]Ratio = 12[/tex]
Note that both have the same equivalent ratios of 12.
So, whatever the scale ratio you use, the equivalent ratio will be the same

Which of the following equations , in it's simplest form , will be equivalent to 3x+2+(-5)?
A: 2+3x+5. B: x-1+x-2+x C: -3-3x-1+x
D: 3-3x
Answer:
The correct answer would be B: x-1+x-2+x
Step-by-step explanation:
First, you would do 2+(-5), from the given equation. Then, it could be simplified to 3x-3. Then, looking at B, you would add the like terms, meaning you would add all the x´s together, and the whole numbers together, giving you 3x-3. I hope I made this easy to understand for you!

A regular octagonal pyramid. Each side of the base is 6 cm long. it has a height of 10cm. Find the surface area of the pyramid
9514 1404 393
Answer:
470.16 cm²
Step-by-step explanation:
The apothem of the base is used for two purposes: to find the area of the base, and to find the slant height of each face.
The apothem of the base for side length s is ...
s/2 = a·tan(π/8)
a = s/(2·tan(π/8)) ≈ 7.24 cm
The slant height of a triangular face is found using the Pythagorean theorem. The apothem of the base and the height are legs of the right triangle whose hypotenuse is the slant height. For slant height x, we have ...
x² = 10² + a² = 100 +52.46
x ≈ √152.46 ≈ 12.35
__
The area of the 8 triangular faces will be ...
A = 1/2Px . . . . where P is the perimeter of the pyramid
The area of the base will be ...
A = 1/2Pa
So, the total surface area is ...
A = 1/2P(a + x) = (1/2)(8)(6 cm)(7.24 +12.35 cm) ≈ 470.16 cm²
The answer is 470.16 cm²
