Answer:
Yes, it would be 225%.
Step-by-step explanation:
If 20/20= 100% you can evenly take out 200% because there is 45/20.
That leaves you with the 5/20.
5/20= 25%.
If we add those two percentages 200% + 25%= 225%.
I hope that made sense lol, have a great day!

determine whether 3y - 7 = 2x -7 represents direct variation or not. If it does, find the
constant of variation.
Answer:
Yes, it represents direct variation.
The constant of variation is 2/3.
Step-by-step explanation:
Rearrange the equation to put it into y = kx form, which is the direct variation equation
3y - 7 = 2x - 7
Add 7 to both sides:
3y - 7 = 2x - 7
3y = 2x
Divide each side by 3:
y = 2/3x
So, the equation is y = 2/3x, which represents direct variation because it is in the form y = kx.
In y = kx, k is the constant of variation. Since the equation is y = 2/3x, k = 2/3.
So, the constant of variation is 2/3.

Why do 3 points make a plane?
In mathematics, a plane is a two-dimensional surface that can be enlarged indefinitely. In order to make a plane we need at least 3 points.
Why do 3 points make a plane?In order to make a plane we need at least 3 points. Let A, B and C are three points which can be defined by two particular vector AB and AC.
As the two vectors is located on the plane, we can use their cross product to define a normal vector on the plane.
As we see a triangle which is a two-dimensional geometric figure that is developed based on 3 points. Triangle is the smallest polygon. The other polygon needs more point for creation.
Therefore, it is proved that minimum three points is mandatory for plane formation.

Lin and Noah are packing small cubes into a cube with an edge length of 1½ inches. Lin is using cubes with an edge length of ½ inch, and Noah is using cubes with an edge length of ¼ inch. Who would need more cubes to fill the 1 1/2 inch cube? Show how you know
Noah needs 108 cubes which is 4 times more than Lin's 27 cubes.
Noah would need more cubes to fill the 1 1/2 inch cube because the cubes he is using have a smaller edge length than the cubes Lin is using. The larger the edge length of the cubes being used, the fewer number of cubes needed to fill a given space.
To see this, you can calculate the volume of the cube being filled by both Lin and Noah. The cube that Lin is filling has a volume of (1.5)^3 = 3.375 cubic inches. The cubes Lin is using have a volume of (0.5)^3 = 0.125 cubic inches. So, Lin needs 3.375/0.125 = 27 cubes to fill the 1.5 inch cube.
The cube that Noah is filling also has a volume of (1.5)^3 = 3.375 cubic inches. The cubes Noah is using have a volume of (0.25)^3 = 0.03125 cubic inches. So, Noah needs 3.375/0.03125 = 108 cubes to fill the 1.5 inch cube.
As we can see, Noah needs 108 cubes which is 4 times more than Lin's 27 cubes.

a circle has a radius of 6 inches and a central angle of 60°. What is the measure of the arc length associated with this angle
3pi inches
2pi inches
pi inches
6pi inches
Answer:
Option B. 2π inches
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 6 in
Centre angle (θ) = 60 °
Length of arc (L) =?
The length of arc can be obtained as follow:
L = 2πr × (θ/360°)
L = 2 × 6 × π × (60/360)
L = 12π × 1/6
L = 2π in
Thus, the length of the arc is 2π in.
On a certain hot summer's day, 311 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled $525 How many children and how many adults swam at the public pool that day?
The number of children that swam in the public pool that day is 194
and the number of adult that swam in the public pool that day is 117
Let x represent the number of children that swam in the public pool that day.
Let y represent the number of adult that swam in the public pool that day.
On a certain hot summer day, 311 people used the public swimming pool. This means that
x + y = 311
The daily prices are 1.50 for children and 2.00 for adults. The receipts for admission totaled to $525. This means that
$1.50x + $2.00y = $525 - - - - - - - -1
Substituting x = 311 - y into equation 1, it becomes
1.50(311 - y) + 2.00y = 525
466.5 - 1.50y + 2.00y = 525
0.5 y = 58.5
y = 117
Substituting y = 117 into x = 311 - y, it becomes
x = 311 - 117
x = 194
Hence , the number of children that swam in the public pool that day is 194 and the number of adult that swam in the public pool that day is 117.

A farmer has a field in the shape of a semicircle of diameter 50 m. The farmer asks Jim to build a fence around the edge of the field. Jim tells him how much it will cost. Total cost = £29. 86 per metre of fence plus £180 for each day's work Jim takes three days to build the fence. Work out the total cost. Show your working out
The total cost is £2033.
The field is in the shape of a semicircle, so the radius of the field is half the diameter or 50 m / 2 = 25 m.
The circumference of a circle is given by 2 * pi * r, where r is the radius of the circle.
So the circumference of the semicircle is 2 * pi * 25 = 50 * pi m.
The cost of the fence is £29.86 per meter. So the cost of the fence is 50 * pi * £29.86 = £1493.
Jim takes three days to build the fence and charges £180 per day.
So the cost for the labour is 3 * £180 = £540.
Adding the cost of the labour to the cost of the fence: £1493 + £540 = £2033
So the total cost is £2033.

A garage charges $55 per tire and $30 dollars per hour of labor. If you need two tries and it takes half an hour to install how much do you pay?
Answer:
$140
Step-by-step explanation:
First, we multiply the amount of tires by the price of the tire. $55 * 2 = $110.
Second, we multiply the amount of hours by the price of an hour of labor. They take half an hour, so we multiply $30 by 1/2.
1/2 * $30 = $15.
Finally, we add the cost of the tires and the labor together.
$110 + $15 = $125

What are solids ?
A three-dimensional object that is closed (which may, according to some terminology conventions, be self-intersecting). A solid is any constrained area of space that is bounded by surfaces, according to Kern and Bland (1948, p. 18). The sphere, cube, cone, and cylinder, as well as the polyhedra more broadly, are some of the most basic solids.
We can see that EJCI is a rhombus and
Area of rhombus is given by
Area of rhombus = Lenth of one diagonal * length of another dialonal / 2
Thus,
EC = (a^2 + a^2 + a^2)^0.5
=> EC = a * (3)^0.5
JI = (a^2 + a^2 )^0.5
=> JI = a * (2)^0.5
So, the area of EJCI = EC * JI / 2
=> Area = (1/2) * (a^2) * (6)^0.5
Area of face = a^2
R = [ (1/2) * (a^2) * (6)^0.5] / a^2
=> R = 1/2 * 6^0.5
So, the required R² is
R^2 = (1/4) * 6
=> R^2 = 3/2

Drag each label to the correct location on the net. Each label can be used more than once, but not all labels will be used.
Identify the dimensions of the net that will give a surface area of 48 sq cm. The area of each part of the net is shown in the figure.
As a result, the response to the query that the area provided With interiors of 32 and 44 square feet, respectively, the future complex will consist of a 60.1-foot circular.
Describe the Area.Finding out how big a rectangle or rectangle is is the simplest (and most used) method. Divide the width by the altitude to find the area of a rectangle. Since all sides of a square are equal in length, determining the area of unit only requires knowledge of the size of one of its sides.
Here,
Here is the formula for area:
The area formula is length times width.
=> 8 × 4
= >32ft²
Following space will be on the trapezoid:
=>(14 + 18)/2 × 4
=> 44ft²
By multiplying the measurement by two, the perimeter will indeed be determined. Knowing this,
= 2(8 + 4) + (14 + 8 + 4 + 5.6 + 4.5)
= 24 + 36.1
= 60.1 ft

Find the length of the third side. If necessary, round to the nearest tenth
Answer: 26
Step-by-step explanation:
In the picture, we are given a right triangle. Based on that, we can use the Pythagorean Theorem, which helps us find the missing side length with the formula [tex]a^2+b^2=c^2[/tex].
a and b represent the legs, and c is the hypotenuse. The hypotenuse is the longest side of the right triangle. It is also the side that is diagonal from the right angle.
In the picture, we are presented with the legs. So, we can plug in the legs into a and b to solve for c.
[tex]a^2+b^2=c^2[/tex] [plug in a and b]
[tex]10^2+24^2=c^2[/tex] [exponent]
[tex]100+576=c^2[/tex] [add]
[tex]676=c^2[/tex] [square root both sides]
[tex]c=26[/tex]
This tells us that the length of the third side is 26.
