A home is purchased for $75,000, and remodelled spending $35,000. five years later, the home is sold for $160,000. what is the capital gain/loss, and at what percent of profit/loss?
Answer:
31.2%
Step-by-step explanation:
75000+35000 = 110000
160000 - 110000 = 50000
50000 ÷ 160000 = 0.312
0.312 x 100 = 31.2 %

Answer:
C
Step-by-step explanation:
The radius of circle 2 is bigger than circle one, so the diameter will be bigger too.
The circumference of the circle 1 is less than the circumference of the circle 2.
What is circumference?Circumference is "a distance around the circle".
According to the question,
The area of the circle 1 is 6π and the area of the circle 2 is 7π.
Area of the circle = π.r²
Radius of the circle 1 is less than the radius of the circle 2 this implies diameter of the circle 2 is greater than diameter of the circle 1.
Hence, the circumference of the circle 1 is less than the circumference of the circle 2.

Steve is painting the ceiling of a room. the ceiling is in the shape of a rectangle. he has enough paint to cover 198 square feet. the length of the ceiling is 13 feet longer than its width. what are the dimensions of the ceiling? need help asap
Answer:
Width = 9ft.
Length=22ft.
Step-by-step explanation:
In a right triangle, a and b are the lengths of the legs and c is the length
of the hypotenuse. If a = 9 centimeters and b = 3 centimeters, what is c? If
necessary, round to the nearest tenth.

10x^3a+6xa^2=2xa( )
Answer:
2xa(5x^2 + 3a).
Step-by-step explanation:
We are factorising:-
Divide the left side by 2xa and place the result in the parentheses:
10x^3a+6xa^2 = 2xa(5x^2 + 3a )
Answer:
2xa(5x² +3a-1)
Step-by-step explanation:
10x³a+ 6xa²-2xa=2xa-2xa
10x³a+ 6xa²-2xa=0
Factor 10x³a+ 6xa²-2xa:
2ax(5x² + 3a -1)
Tua wanted to teach his pet raven to count because they are very smart birds. He used various fruits and nuts to represent numbers. A peanut = 1 A grape = 2 peanuts 14 is represented by an acorn and 3 grapes. An acorn is worth half a plum. What is the value in fruits and nuts, of two plums and a peanut, divided by a grape and a peanut?
The value of two plums and a peanut, divided by a grape and a peanut is 11
How to solve the expression?The given parameters are:
Peanut = 1Grape = 2 Acorn + 3 grapes = 14Acorn = 1/2 PlumSubstitute Grape = 2 in Acorn + 3 grapes = 14
Acorn + 3 *2 = 14
Acorn + 6 = 14
Subtract 6 from both sides
Acorn = 8
Substitute Acorn = 8 in Acorn = 1/2 Plum
8 = 1/2 Plum
Multiply both sides by 2
Plum = 16
So, we have:
Peanut = 1
Grape = 2
Acorn = 8
Plum = 16
The value of two plums and a peanut, divided by a grape and a peanut is:
(2 plums + peanut)/(grape + peanut)
This gives
(2 * 16 + 1)/(2+ 1)
Evaluate
11
Hence, the value of two plums and a peanut, divided by a grape and a peanut is 11

Answer:
walk area = 125.6 m²
Step-by-step explanation:
You are asked for the area of a sidewalk of given width that is around a circle of given radius. The pattern you're asked to fill in would have you compute the area of the inner circle, and of the outer circle, then find the difference between the areas.
__
The formula for the area of a circle is ...
A = πr²
bigger circleThe radius is shown as 11 m, so its area is ...
A = π(11 m)² = 121π m² = 379.94 m²
smaller circleThe radius is shown as 9 m, so its area is ...
A = π(9 m)² = 81π m² = 254.34 m²
area differenceThe difference between the two areas is ...
walk area = big circle area - small circle area
walk area = 379.94 m² -254.34 m² = 125.6 m²
_____
Additional comment
The area can also be computed by multiplying the centerline length of the sidewalk by its width. The center of the walk is (9+11)/2 = 10 m from the centers of the circles, so the circumference (centerline length) is
C = 2πr = 2(3.14)(10 m) = 62.8 m
The width of the sidewalk is 11 -9 = 2 meters, so its area is ...
(2 m)(62.8 m) = 125.6 m² . . . . sidewalk area

if a square is drilled out from a cylinder what will be the lateral surface area,total surface area,base area and the volume of the cylinder
The cylinder is a three-dimensional shape and it has a radius, diameter and a height
How to determine the lateral surface area?Assume the square has the following dimensions:
Base dimensions = x
Height = h
Assume the cylinder has the following dimensions:
Radius = r
Height = h
When the square is drilled out, the lateral surface area would be:
Lateral Area = Cylinder - Square
This gives
[tex]Lateral = 2\pi rh - 4xh[/tex]
Factor out 2h
[tex]Lateral = 2h( \pi h - 2x)[/tex]
How to determine the total surface area?Using the same dimensions in (a), we have:
Total surface Area = Cylinder - Square
This gives
[tex]Area = 2\pi r(r +h) - 2(2x^2 - xh)[/tex]
Factor out 2
[tex]Area = 2[\pi r(r +h) - (2x^2 - xh)][/tex]
How to determine the base area?Using the same dimensions in (a), we have:
Base area = Cylinder - Square
So, we have:
[tex]Base = \pi r^2 - x^2[/tex]
How to determine the volume?Using the same dimensions in (a), we have:
Volume = Cylinder - Square
So, we have:
[tex]Volume = \pi r^2h - x^2h[/tex]
Factor out h
[tex]Volume = h(\pi r^2 - x^2)[/tex]

Step-by-step explanation:
You have to simplify the brackets in turn.
3 times x^3- 7x+1 = 3x^3- 21x+ 3
then do 3 times x + 4= 3x + 12
you then add them all together, if they have a power add them, if they just have an x add them, and if they are just a number add them.
So it goes to 3x^3- 24x - 9,
this is because 3x^3 cant be added/ subtracted by anything, -24x is made from -21x- 3x, and -9 is made from 3 - + 12, so this means 3 - 12 = -9.

The price of a box of colored pencils increased from $8.00 to $8.48. What was the percent increase in the price?
Step-by-step explanation:
100% = $8.00
1% = 100%/100 = 8/100 = $0.08
the price went up by $8.48 - $8.00 = $0.48.
how many % is this ?
as many % as 1% fits into this difference :
0.48 / 0.08 = 6%
the price increase was 6%.
