The sector COB is cut from the circle with center O. The ratio of the area of the sector removed from the whole circle to the area of the sector removed from the inner circle is R^2/r^2 .
Answer:
[tex]Ratio = \frac{R^2 - r^2 }{ r^2}[/tex]
Step-by-step explanation:
Given
See attachment for circles
Required
Ratio of the outer sector to inner sector
The area of a sector is:
[tex]Area = \frac{\theta}{360}\pi r^2[/tex]
For the inner circle
[tex]r \to radius[/tex]
The sector of the inner circle has the following area
[tex]A_1 = \frac{\theta}{360}\pi r^2[/tex]
For the whole circle
[tex]R \to Radius[/tex]
The sector of the outer sector has the following area
[tex]A_2 = \frac{\theta}{360}\pi (R^2 - r^2)[/tex]
So, the ratio of the outer sector to the inner sector is:
[tex]Ratio = A_2 : A_1[/tex]
[tex]Ratio = \frac{\theta}{360}\pi (R^2 - r^2) : \frac{\theta}{360}\pi r^2[/tex]
Cancel out common factor
[tex]Ratio = R^2 - r^2 : r^2[/tex]
Express as fraction
[tex]Ratio = \frac{R^2 - r^2 }{ r^2}[/tex]
A factory inspector found 3 defective microchips out of a total of 750
microchips made. Which proportion can be used to predict the number of
defects, x, in a batch of 10,000 microchips?
Answer:
Option B
Step-by-step explanation:
Proportion of number of defective pieces to the number of microchips in a batch can be represented by the ratio = [tex]\frac{\text{Number of microchips not in good condition}}{\text{Total numbers of microchips}}[/tex]
If 3 microchips are defective in a batch of 750 microchips,
Proportion = [tex]\frac{3}{750}[/tex]
If 'x' chips are defective in a batch of 10000 microchips,
Proportion = [tex]\frac{x}{10000}[/tex]
If both the proportions are equal,
[tex]\frac{3}{750}=\frac{x}{10000}[/tex]
Therefore, Option B will be the answer.

What is the vertex of the quadratic function y=-x²+6x+7?
Answer:
(3,16)
Step-by-step explanation:
Factor the equation to find out that the roots are 7 and -1. The vertex's x will be in the center of these two points, so the center point between 7 and -1 is 3. Continue to substitute the x in the equation with 3 to get the other coordinate for vertex.

stay safe healthy and happy...14) When did the high temperature occur?
Please help
Answer:
D; 15
Step-by-step explanation:
Because the highest point on the graph is at 15 (or 3 am), that would be the highest temperature. (Also, none of the other choices make sense; they are all at relatively low temperatures).
MARKING BRAINLIEST IF CORRECT + 50 POINTS!!!!
Part A: If (62)x = 1, what is the value of x? Explain your answer. (5 points)
Part B: If (60)x = 1, what are the possible values of x? Explain your answer. (5 points)
pls explain
Answer:
Part A : 1/62 Part b : 1/60
Step-by-step explanation:
Well lets start with part A
(62)x=1
anything in parenthesis means multiply
62x= 1
divide everything by 62 to get x by itself
x= 1/62
Part A : 1/62
Part B : 60x = 1
x = 1/60

find the value of x HELP PLS
Answer:
x= 36
Step-by-step explanation:
both angles together are supplementary and will form 180
Therefore, you know the missing angle can be found by substracting 108 from 180
180 - 108 = 72
72 = 2x
Answer:
36°
Step-by-step explanation:
2x+108°=180°
2x=72°
x=36°

Find the value of x.
Answer:
16 = x
Step-by-step explanation:
A triangle has 180 degrees. Use this to solve for x
180=(9x-8)+(x+2)+(x+10)
180 = 9x + x + x - 8 + 2 +10
180 + 8 -2 - 10 = 11 x
176 = 11x
176/11 = x
16 = x

Answer:
c= 15 mi
Step-by-step explanation:
Pythagorean theorem. a^+b^=c^
Square root of that
answer 15
Answer:
15
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + 12 ^2 = c^2
81+144= c^2
225 = c^2
Take the square root of each side
sqrt(225) = sqrt(c^2)
15 =c
