The selling price of lumber at Home Depot is $4,000, percent markup on cost is 30%. Calculate the actual cost. (Round your answer
to the nearest cent.)
Step-by-step explanation:
Selling Price=$4000
Profit Percent=30%
Cost Price;
[tex] \frac{100}{100 + pp} \times 4000 [/tex]
[tex] \frac{100}{100 + 30} \times4000 [/tex]
[tex] \frac{100}{130} \times 4000 [/tex]
[tex] \frac{10}{13} \times 4000[/tex]
[tex] \frac{40000}{13} [/tex]
$3,076.923
=$3,077.000
I am not really Good at rounding forgive me Confirm from someone please.

7.5/x= 30/16
Answer:
4
Step-by-step explanation:
I divided 30/16 and got 1.875, then I knew that 7.5 would have to have the same answer. I did a process of elimination by dividing 7.5 by numbers at random and finally divided by 4 and got the answer. Another way to get the answer would be to cross multiply the equation.

A rectangle has a perimeter of 32 in. Find the length and width of the rectangle under which the area is the largest.
a. Let the width to be x and the length to be y , then the quantity to be maximized is (expressed as a function of both x and y) A=_____
b. The condition that x and y must satisfy is y=______
Answer:
Length of the rectangle is 8 in and the breadth is 8 in.
a. [tex]A=xy[/tex]
b. [tex]y=16-x[/tex]
Step-by-step explanation:
Length = x
Breadth = y
Area is given by [tex]A=xy[/tex]
Perimeter of rectangle is given by
[tex]2(x+y)=32\\\Rightarrow x+y=16\\\Rightarrow y=16-x[/tex]
The condition that x and must satisfy is [tex]y=16-x[/tex]
So, area is
[tex]A(x)=x(16-x)\\\Rightarrow A(x)=16x-x^2[/tex]
Differentiating with respect to x we get
[tex]A'(x)=16-2x[/tex]
Equating with zero
[tex]0=16-2x\\\Rightarrow x=\dfrac{16}{2}\\\Rightarrow x=8[/tex]
Double derivative of A(x)
[tex]A''(x)=-2[/tex]
So [tex]A''(x)<0[/tex] which means [tex]A(x)[/tex] is maximum at [tex]x = 8[/tex]
[tex]y=16-x=16-8\\\Rightarrow y=8[/tex]
So length of the rectangle is 8 in and the breadth is 8 in.

Answer:
Step-by-step explanation:
1). ∠7 ≅ ∠ 2 (alternate exterior)
m∠7 = m∠2 = 30°
2). ∠4 and ∠1 are supplementary angles
m∠1 = 180° - 72° = 108°

Q4: Write the equation in slope-intercept form of the line that is perpendicular to
the graph of each equation and passes through the given point.
y = -5x + 1; (2, -1)
Answer:
5y = x + 11
Step-by-step explanation:
Given parameters:
Equation of the line ;
y = -5x + 1
Coordinates = (2, -1)
Find the equation of a line perpendicular;
Solution:
A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.
Equation of a straight line is expressed as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
So, the slope of the new line perpendicular is [tex]\frac{1}{5}[/tex] ;
Now let us find the y-intercept of the new line;
x = -1 and y = 2
2 = [tex]\frac{1}{5}[/tex] x (-1) + c
c = 2 + [tex]\frac{1}{5}[/tex] = [tex]\frac{11}{5}[/tex]
The equation of the new line is;
y = [tex]\frac{1}{5}[/tex]x + [tex]\frac{11}{5}[/tex]
or multiply through by 5;
5y = x + 11
