what is the ratio of the area of circle C to circle E, as shown below .
a) 16/3
b) 16/9
c) 8/6
d) 4/3
Answer: 16/9
Step-by-step explanation:
Area of circle = pi * r^2
Circle C = 16pi
Circle E = 9pi
Ratio of C to E = C/E
16pi/9pi = 16/9
The ratio of the area of circle C to circle E is 16/9.
Hence, option B is the right choice.
How is the area of a circle determined?The area of a circle is the product of π, a constant, and the square of its radius (r). The radius of the circle is any line connecting the center of the circle to any point on its circumference (boundary).
Therefore, the area of a circle = πr².
How to solve the question?In the question, we are asked to determine the ratio of the area of circle C to circle E, from the given diagram.
In the diagram, for circle C,
The center is at the point (-3, 1).
For radius, we choose the point (1, 1) on the circumference.
Therefore, radius = √((1 - (-3))² + (1 - 1)²) {using the distance formula between the point (x1, y1) and (x2, y2), given as:
d = √((x1 - x2)² + (y1 - y2)²)}.
or, radius = √(4)² = √16 = 4.
Therefore, area = πr² = π4² = 16π.
In the diagram, for circle E,
The center is at the point (4, 9).
For radius, we choose the point (1, 9) on the circumference.
Therefore, radius = √((1 - 4)² + (1 - 1)²) {using the distance formula between the point (x1, y1) and (x2, y2), given as:
d = √((x1 - x2)² + (y1 - y2)²)}.
or, radius = √(-3)² = √9 = 3.
Therefore, area = πr² = π3² = 9π.
Therefore, the ratio of the area of circle C to circle E = 16π/9π = 16/9.
Hence, option B is the right choice.

Adi is t inches shorter than sunnee sunnee is n inches taller which expression repesent adies hight in inches
Answer:
adi's height = n-t inches
Step-by-step explanation:
from this question
we have Adi to be t inches shorter than sunnee.
sunnee's height = n inches tall
to get adis height, we have to subtract the height difference t from sunnee's height.
the height difference is how many inches by which Adi is shorter = t
adies height = sunnee's height, n - difference in height, t
= (n-t) inches
this expression represents adis height in inches .
Chris is tiling the bathroom floor. For a tile to fit in the corner of the room, he must cut it as shown below.
If x = 3, y = 12, and z = 9, what is the area of the tile being used?
A.
54 sq ft
B.
108 sq ft
C.
58.5 sq ft
D.
81 sq ft
Answer:
D. 81 sq. ft.
Step-by-step explanation:
We know x, y, and z's lengths. Those are 3, 12, and 9 respectively.
I first imagined a 12 by 9 rectangle and then figured about the area of the shaded part.
The 12 by 9 rectangle is 108 sq ft, But there is a empty part on the top left. That would be a 9 ft by 6 ft triangle.
The area of a triangle can be figured out with this formula: A = bh/2 Substitute b and h for 9 and 6 respectively.
A = (9 * 6)/2
A = 54/2
A = 27 sq. ft.
Now, subtract 27 from 108 to get the area of the shaded part.
108 - 27
81 sq. ft.
The area of the tile being used is 81 sq. ft.

Write in point slope form an equation of the line that passes through the given point and has the slope. (-2, 9) and m = 5
Answer:
The point-slope form of an equation of the line is:
[tex]y-9 = 5(x+2)[/tex]
Step-by-step explanation:
Given
Slope m = 5
Point (-2, 9)
Point slope form of an equation of a line:
Point slope form of an equation of a line is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case,
m = 5(x₁, y₁) = (-2, 9)substituting the values m = 5 and the point (x₁, y₁) = (-2, 9) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 9 = 5 (x - (-2)[/tex]
[tex]y-9 = 5(x+2)[/tex]
Therefore, the point-slope form of an equation of the line is:
[tex]y-9 = 5(x+2)[/tex]
Isabella is deciding between two parking garages. Garage A charges an initial fee of
$4 to park plus $3 per hour. Garage B charges an initial fee of $12 to park plus $2 per
hour. Let A represent the amount Garage A would charge if Isabella parks for t
hours, and let B represent the amount Garage B would charge if Isabella parks for t
hours. Write an equation for each situation, in terms oft, and determine the hours
parked, t, that would make the cost of each garage the same.
Answer:
i. A = 4 + 3t .......... 1
B = 12 + 2t .......... 2
ii. The hours required would be 8 hours.
Step-by-step explanation:
The charges at each of the garages can be expressed as;
i. For garage A,
A = 4 + 3t .......... 1
ii. For garage B,
B = 12 + 2t .......... 2
where A is the amount charged at garage A, B is the amount charged at garage B, and t is the number of hours.
To determine the number of hours parked that would make the cost of each garage the same.
Let:
equation 1 = equation 2
4 + 3t = 12 + 2t
collect like terms
3t - 2t = 12 - 4
t = 8
The hours that would make the cost of each garage the same is 8 hours.

Answer:
<A = 44
Step-by-step explanation:
A triangle is 180 degrees
(x+59) + (x+51) + 84 = 180 >> add everything on the left side
2x + 194 = 180 >> subtract both sides by 194
2x = -14 >> divide both sides by 2 to get x alone
x = -7
since you are finding A<, substitute
<A = x + 51
<A = (-7) + 51
<A = 44
