Answer:
the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant
Step-by-step explanation:
The computation of the area and the ratio of the area is shown below:
The ratio of the drawing area to the actual area is
= ((1 cm) ÷ (4 ft))²
= (1 cm²) ÷ (16 ft²)
Now the actual floor area is
(16 ft²) ÷ (1 cm²) = actual area ÷ (49 cm²)
= (16 ft²) × 49 ÷ 1
= 784 ft²
hence, the area of the actual floor is 784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant
What is the relationship between numerator and denominator?
The denominator of a fraction represents the number of equal parts in a whole, while the numerator represents the number of parts considered.
What is a fraction?A fraction is a portion of a larger whole. The number is expressed in arithmetic as a quotient, which is the numerator divided by the denominator.In a simple fraction, they are both integers. A complex fraction has a fraction in either the denominator or the numerator. The denominator of a proper fraction is less than the numerator. A numerator is the total number of parts.A denominator is the lowest number in a fraction that represents the number of equal parts into which an item is divided. It is the fraction divisor.A fraction as p/q can be thought of as p parts, which is the numerator of a whole object, divided into q equal parts which is denominator.To learn more about fraction refer to :

Is equidistant from all points on the circle?
The point from which all the points on a circle are equidistant is called the center of the circle, and the distance from that point to the circle is called the radius of the circle. A circle is named with a single letter, its center.
Every point in a circle is equally distance from the center. Similar to a sphere, every point on a sphere is equally distance from the center.
Two equal chords on a circle indicate that they are equally spaced from the circle's center.
The incenter of a triangle is the point that is equally far from each of its sides. A median is a line segment that has one of its endpoints in the vertex of a triangle and the other endpoint in the midpoint of the side opposite the vertex. The three medians of a triangle meet in the centroid.

Six lines are drawn, no two of which are parallel. If no more than two of the lines pass through any one point, what is the number of triangles formed?
Answer: I believe 20.
Take one pair of lines. They will intersect at a point (no lines parallel). The other four lines will intersect at different points (no more than two lines through one point) giving four triangles. There are 6C2 = 15 different pairs of lines so 15*4 = 60 triangles. However, each triangle will come from three different points so we need 60/3 = 20 distinct triangles.
EDIT: Now that I’m more awake, it occurs to me there is a much easier answer. Since no two lines are parallel and no three lines are coincident, every combination of three lines must form a triangle. There are 6C3 = 20 triangles.

Step-by-step explanation:
Alyssa is 1.65 meters tall. At 11 a.m., she measures the length of a tree's shadow to be 27.75 meters. She stands 23.5 meters away from the tree, so that the tip of her shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
Answer:
The tree is 10.77 meters tall.
Step-by-step explanation:
The given diagram is an example of similar triangles. Look at the image I attached to my response to see this problem in terms of triangles.
The triangle that is formed by Alyssa and her shadow and the triangle that is formed by the tree and its shadow is an example of similar triangles because they both share an internal angle.
As per the similar triangles theorem, the ratios of the corresponding sides of both sides are proportional.
Thus, we have to make a proportion of the corresponding sides of both triangles to solve for the height of the tree. Let x = the height of the tree.
Proportion: [tex]\frac{BE}{BC} = \frac{DE}{AC}\\[/tex]
BE = 4.25 meters
BC = 27.75 meters
DE = 1.65 meters
AC = x meters
[tex]\frac{4.25}{27.75} = \frac{1.65}{x}[/tex]
Now, cross multiply to solve for x.
[tex]4.25x = 1.65(27.75)\\4.25x = 45.7875\\x = 10.77[/tex]
∴ The tree is 10.77 meters tall!
The height of the tree to the nearest hundredth of a meter is,
⇒ 10.77 meters
We have to given that;
Alyssa is 1.65 meters tall. At 11 a.m., she measures the length of a tree's shadow to be 27.75 meters. She stands 23.5 meters away from the tree.
Now, we can make a proportion of the corresponding sides of both triangles to solve for the height of the tree.
And, Let us assume that,
x = the height of the tree
Hence, We get;
⇒ (27.75 - 23.5) / 27.75 = 1.65 / x
Solve for x;
⇒ 4.25 / 27.75 = 1.65 / x
Cross multiply we get;
⇒ 4.25x = 1.65 x 27.75
⇒ 4.25x = 45.78
⇒ x = 10.77 meters
Thus, The height of the tree to the nearest hundredth of a meter is,
⇒ 10.77 meters

Which equation is the inverse of 2 x 2 )= 8 7 y?
[tex]y=2[/tex] ± [tex]\sqrt{28+4x}[/tex] is the equation that equals 2(x - 2)2 = 8(7 + y).
Addition and subtraction, multiplication, and division are examples of inverse operations, which are pairs of mathematical operations where one operation reverses the effects of the other. In most cases, a number's inverse refers to its reciprocal, or x - 1 = 1 / x. When a number is combined with its reciprocal, or inverse, the result is 1, or 1.
Considering the equation:
[tex]2(x-2)^2=8(7+y)[/tex]
Change the x and y variables.
[tex]2(y-2)^2=8(7+x)[/tex]
In terms of x, solve for y.
We have two sides, therefore divide them by two.
[tex](y-2)^2=4(7+x)[/tex]
Using the distribution property, [tex]a.(b+c)=a.b+a.c[/tex]
[tex](y-2)^2=28+4x[/tex]
Square-rooting both sides yields:
[tex]y-2=[/tex]±[tex]\sqrt{28+4x}[/tex]
our two sides plus two;
[tex]y=2[/tex]±[tex]\sqrt{28+4x}[/tex]
As a result, equation [tex]y=2[/tex]±[tex]\sqrt{28+4x}[/tex] is the opposite of [tex]2(x-2)^2=8(7+y)[/tex]
The complete question is:-
Which equation is the inverse of 2(x – 2)2 = 8(7 + y)?
Options:

The Percent error of the given problem is; 33.33%
How to find the percentage error?We are given;
Amount spent by John on shopping = $75
Amount expected to spend = $100
Since this is what was given then it means we will have the following;
The approximate value to be spent = 100 dollars
Exact Value spent = 75 dollars
Therefore, the error made is;
Error = Approximate value - Exact value
Error = 100 - 75
Error = 25 dollars
Thus, the error when it is absolute is;
Absolute Error = ±25 dollars
Now, the ratio will be;
Ratio(e) = Error/exact value spent
e = 25/75 = 0.3333
