It will much help, and easier for answering.
The radius of the other similar circle is, 6 inches
What is a circle?In mathematics, the circle is a two dimensional rounded figure which has no corner edges.
Standard form = (x - a)² + (y - b)² = r²
Angle = Arc / Radius
Given that,
The two arc lengths for the circles are equal
One circle has a radius of 8 inches and a shaded sector with an angle measure of 90 degrees
The second circle has a shaded sector with an angle measure of 120 degrees
The radius of second circle = ?
α = 90°
It is known that,
π radian = 180°
1° = π/180 radian
Now,
α = 90 × π/180
= π/2
β = 120°
= 120 × π/180
= 2π/3
In Circle 1,
Angle = Arc / Radius
π/2 = Arc/8
Arc = 4π
In both the circles, length of arc is same,
In Circle 2,
Angle = Arc / Radius
2π/3 = 4π/Radius
Radius = 6
Thus, the radius of second circle is 6 inches

Bryn is riding his bicycle at a constant speed from school to the library. His distance from the library in kilometers x hours after leaving school can be modeled by the equation Y=20-12X. What is the distance between the school and the library in kilometers?
Answers
Answer:
The distance is 20km
Step-by-step explanation:
Given
[tex]y = 20 - 12x[/tex]
Required
The distance between [tex]the\ library\ and\ the[/tex] school
The function represents the distance [tex]y = 20 - 12x[/tex]
So, when x = 0.
This implies that he has not started moving.
So:
[tex]y = 20 - 12 * 0[/tex]
[tex]y = 20 - 0[/tex]
[tex]y = 20[/tex]

Answers
Answer:
x = 31 and y= 11
Step-by-step explanation:
Since sum f angles on a straight line is 180°, hence;
2x+8+3x+17 = 180
Collect like terms
5x+25 = 180
5x = 180-25
5x = 155
x = 155/5
x = 31°
Similarly;
3x+17+5y+15 = 180
Substitute x = 31 into the equation
3(31)+17+15+5y = 180
93+32+5y = 180
125+5y =180
5y = 180-125
5y = 55
y = 55/5
y = 11°
Hence x = 31 and y= 11

Answer:
The value is 0.025
Step-by-step explanation:
We get the z-score that is equal to the given value
Mathematically we have this as:
z-score = (x-mean)/SD
x = 93
mean =79
SD = 7
So we have the z-score as;
z-score = (93-79)/7 = 14/7 = 2
So we want to calculate the probability equal to the calculated z-score value of 2
Using the standard normal distribution table, we have this value as;
1 - 0.975= 0.025
A balloon lifts off the ground and reaches a height of 200m. The total mass of the balloon is 1000 kg. What is the GPE of the balloon?
Answers
Answer:
1,960,000Joules
Step-by-step explanation:
Gravitational Potential Energy is expressed as;
GPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Given
m = 1000kg
h = 200m
g = 9.8m/s
Substitute;
GPE = 1000 * 9.8 * 200
GPE = 9800 * 200
GPE = 1,960,000Joules
Hence the GPE of the balloon is 1,960,000Joules

Dividindo-se o diâmetro de um fio de cabelo pelo diâmetro de uma célula de Escherichia coli, obtém-se, como resultado a) 200. B) 135 . C) 140. D) 125.
Answers
Answer:
125
Step-by-step explanation:
The cells of the bacterium Escherichia coli have a cylindrical shape, with 8 x 10−7 meters in diameter. The diameter of a hair is approximately 1 x 10−4 meters. Dividing the diameter of a hair by the diameter of a cell of Escherichia coli gives, as a result, a) 200. B) 135. C) 140. D) 125
We are carrying out division operation
The diameter of a hair ÷ The diameter of a cell of Escherichia
The cells of the bacterium Escherichia coli have a cylindrical shape = 8 x 10^−7 meters in diameter.
The diameter of a hair is approximately 1 x 10^−4 meters
Therefore:
1 x 10^−4 meters ÷ 8 x 10^−7 meters
