Answer:0.82
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82

Find all exact solutions
2cos^2x=sinx+1
Please show work thank you!
Answer:
[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]2\cos^2(x)=\sin(x)+1[/tex]
And we want to find all solutions for x.
First, we should put the equation into terms of only one trigonometric ratio.
Since we are given cos²(x), we can turn this into sine. Recall the Pythagorean Identity which states:
[tex]\sin^2(x)+\cos^2(x)=1[/tex]
Therefore:
[tex]\cos^2(x)=1-\sin^2(x)[/tex]
By substitution:
[tex]2(1-\sin^2(x))=\sin(x)+1[/tex]
Distribute:
[tex]2-2\sin^2(x)=\sin(x)+1[/tex]
Isolate the equation:
[tex]2\sin^2(x)+\sin(x)-1=0[/tex]
We can factor:
[tex](2\sin(x)-1)(\sin(x)+1)=0[/tex]
Zero Product Property:
[tex]2\sin(x)-1=0\text{ or } \sin(x)+1=0[/tex]
Solve for each case:
[tex]\displaystyle \sin(x)=\frac{1}{2}\text{ or } \sin(x)=-1[/tex]
We can use the unit circle.
sin(x) = 1/2 for every π/6 and 5π/6. So, it will continue every 2π.
sin(x) = -1 every 3π/2. And this will also continue every 2π.
Hence, our solutions are:
[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]
Note:
If you only need the solutions within the interval [0, 2π), then it is:
[tex]\displaystyle x=\left\{\frac{\pi}{6}, \frac{5\pi}{6}, \frac{3\pi}{2}\right\}[/tex]

The school orchestra sells carnations on Valentine's Day for $2 each. They buy the carnations that they sell from a local florist for $0.50 each plus a one-time $18 delivery charge. Write a system of equations that describes this situation and solve it using your preferred method.
Answer:
2x - (0.50x + 18) = profit
Step-by-step explanation:
x = number of carnations, for example if 3 carnations were sold, $6 from sales - (1.50 + 18) = profit. The 50 cents from each carnation that they bought to sell, plus 18 delviery fee. Hope this helped! Good luck!
The diameter of the circle is 9 feet. What is the circumference of the Circle?
Answer:
(ABOUT) 28.27433
Step-by-step explanation:
C = 2πr or dπ (because 2*r = d)
For this case:
C = dπ
C = 9π
C = 28.27433
You can round if you want to (like 28.3 or 29.27).
a plane departs an airport and mistakenly travels due west at 500mph for 30 minutes. the pilot realizes that the correct destination (airport b) was actually 600 miles away at a bearing of 60 degrees west from airport a. how far is the airplane from its original destination now?
Answer:
403 miles
Step-by-step explanation:
500 mph is 500 miles per hour
30 minuites is half an hour, so that is 250 miles west
60 degrees west, 600 miles away
so it is a triagle of 30 60 and 90.
600 is the hypotenuse of the 30 60 90 triangle
we need to find the height of the 30 60 90 triangle
using the special rule, the height is 300
the length of the 30 60 90 triangle is 300rt3
so 300rt3 - 250 is the length of another triangle.
height is still 300
hypotenuse is the distance of the actual area minus the plane's current position
(300^2 + (300rt3-250)^2)^1/2 is about 403.351433

Sia sells large candles for $3 each and small candles for $2 each. She sold 17 candles for $46.00. How many of each size candle did she sell? 4 small and 13 large candles 5 small and 12 large candles 12 small and 5 large candles 13 small and 4 large candles
Answer:
The number of large size candles sells are 12 and the number of small size candles are 5 .
Step-by-step explanation:
As given Sia sells large candles for $3 each and small candles for $2 each.She sold 17 candles for $46.00.Let us assume that the large size candle sells are x .Let us assume that the small size candle sells are y. Equation becomes
x + y = 17
3x + 2y = 46
Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .
3x - 3x + 2y - 3y = 46 - 51
-y = - 5
y = 5
Put in the equation x + y = 17 .
x + 5 = 17
x = 17 - 5
x = 12
Therefore the number of large size candles sells are 12 and the number of small size candles are 5
