105. A circular sector has an 8.26-inch radius and a 12.84-inch arc length. There is another sector that has the same area and the same perimeter. What are its measurements
Answer:
Area of another sector=[tex]53.0292 in^2[/tex]
Perimeter of another sector=29.36 in
Step-by-step explanation:
We are given that
Radius, r=8.26 in
Arc length , l=12.84 in
Area of circular sector=[tex]\frac{arc\;length} {Circumference\;of\;circle}\times \pi r^2[/tex]
Area of circular sector=[tex]\frac{l}{2\pi r}\times \pi r^2=\frac{l}{2}\times r[/tex]
Where Circumference of circle=[tex]2\pi r[/tex]
Substitute the values
Area of circular sector=[tex]\frac{12.84}{2}\times (8.26}[/tex]
Area of circular sector=[tex]53.0292 in^2[/tex]
Area of another sector=[tex]53.0292 in^2[/tex]
Perimeter of circular sector=8.26+8.26+12.84
Perimeter of circular sector=29.36 in
Perimeter of another sector=29.36 in
As the radius of a sector decreases, the arc length increases to have an
equal area with a sector with a radius that is longer.
The measurements of another sector with the same perimeter and area are;
The radius of an alternative sector is 6.42 inchesThe arc length of an alternative sector is 16.52 inchesReasons:
Radius of the sector, r = 8.26 inches
Arc length of the sector = 12.84 inches
Perimeter of sector = 2·r + Arc length
Perimeter of the given sector = 2 × 8.26 inch + 12.84 inch = 29.36 inch
Circumference of the circle = 2 × 8.26 × π = 16.52·π
Area of the given circle, A = π × 8.26² = 68.2276·π
[tex]\displaystyle Area \ of \ sector = \frac{12.84}{16.52 \cdot \pi} \times 68.2276 \cdot \pi = 53.0292[/tex]Area of the sector, A = 53.0292 inch²
Therefore, we have;
2·R + A = 29.36 inches
[tex]\displaystyle \mathbf{\frac{A}{2\cdot \pi \cdot R} \times \pi \cdot R^2} = 53.0292[/tex]
A·R = 53.0292 × 2
[tex]\displaystyle New \ arc \ length, \ A = \mathbf{\frac{53.0292 \times 2}{R}}[/tex]
Which gives;
[tex]\displaystyle 2 \cdot R + \frac{53.0292 \times 2}{R} = 29.36[/tex]
[tex]\displaystyle R + \frac{53.0292 }{R} = 14.68[/tex]
R² + 53.0292 = 14.68·R
R² - 14.68·R + 53.0292 = 0
Factorizing with a graphing calculator, gives;
(R - 6.42)·(R - 8.26) = 0
R = 6.42 or R = 8.26
The measurement of R = 8.26 is for the first sector
Given that the sectors are different, we have;
The radius of the other sector, R = 6.42 inchesThe arc length, A = 29.36 - 2·R
∴ A = 29.36 - 2 × 6.42 = 16.52
The arc length of the other sector, A = 16.52 inchesLearn more about the sector of a circle here:

The ratio of people who have dogs to people who have cats is 4 to 2. If there are 40 people, how many have cats?
Answer:
13 people
Step-by-step explanation:
let ratio be 4x and 2x
4x+2x=40
6x=40
x=40/6
x=6.66
so,
2x=2×6.66
=13.33
approx 13
again
4x=4×6.66
=26.64
approx 27.
The effects of caffeine on the body have been extensively studied. In one experiment1, researchers examined whether caffeine increases the rate at which people are able to tap their fingers. Twenty students were randomly divided into two groups of
Question attached
Answer and explanation:
Here we would use the two sample t test. In finding the hypotheses for a two sample t test we test the sample mean of one group against the other group to determine if there is a statistical difference or they are equal. We have this to compare the mean finger tapping rate of the two groups being tested in the question. Our null and alternative hypotheses here are:
H0: u1 = u2 null hypothesis
H1: u1 > u2 alternative hypothesis
Where u1 and u2 are the sample means for each group in the caffeine experiment

The distance between two towns is 120 kilometers there are approximately 8 kilometers in 5 miles which measurement is closest to the number of mules between these two towns
Answer:
75 Kilometers
Step-by-step explanation:
We have been given that the distance between two towns is 120 km.
We are also told that there are approximately 8 km in 5 miles. Let us find number of miles per km by dividing 5 by 8.
\text{Number of miles in 1 km}=\frac{5\text{ miles}}{\text{8 Km}}
\text{Number of miles in 1 km}=0.625\frac{\text{ miles}}{\text{ Km}}
Therefore, there are 0.625 miles in 1 km.
To convert our given distance into miles we will multiply our given distance by number of miles in 1 km.
\text{Number of miles in 120 km}=120\text{ km}\times \frac{0.625\text{ miles}}{\text{ km}}
\text{Number of miles in 120 km}=120\times 0.625\text{ miles}
\text{Number of miles in 120 km}=75\text{ miles}
Therefore, the distance between two towns is 75 miles.
