The figure below shows a shaded circular region inside a larger circle:
r3 inches
R5 inches
What is the probability that a point chosen inside the larger circle is not in the shaded region?
O 24%
O 36%
O 50%
O 64%
Answers
Answer:
Probability is 64%
Step-by-step explanation:
Given the smaller circle which is shaded whose radius is denoted by r and the largest circle whose radius is denoted by R
r = 3 inches
R = 5 inches
Step 1 : To calculate the area of shaded region.
Area of circle =
⇒ Area =
= square inches
Step 2 : To calculate the area of larger circle.
Area of circle =
⇒ Area =
= square inches
Step 3 : Calculate the probability that a point chosen from shaded region
Probability = Area of shaded region/Area of larger circle.
= /
=
= 0.36 = 36%
Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.
Probability = 1 - 0.36
= 0.64 = 64%
Hence the probability is 64%

Answer:
20, 12, and 16
Step-by-step explanation:
So we know that y=4x
This basically means y=4*x
So we can plug the values for x shown on the table below to find y.
when x=5:
y=4*5
=
y=20
So for the first fill in box, its 20
Next is x=3:
y=4*3
=
12
So for the next fill in box it is 12.
Finally we have x=4:
y=4*4
=
y=16
So the for the finally box it is 16.
Hope this helps!

(if he gathers 4 coins each month you will need the variable by it. he was given 20 coins so it is added on to how many coins he has. plus it would be greater than because the question asked when he will have MORE than 50 coins.)
We know that each month, he gets 4 coins to add to his collection so that would represent 4m. And we know that he started with 20. The last thing that we know is that we will need a greater than symbol to represent more than 50. Therefore the equation is
20 + 4m > 50.

How do I add a percentage (%) tip to a total of a bill? (Ex - Total : 3.00 with a %18 tip)
Answers
To calculate a gratuity or tip on any calculator it is a simple multiplication. In general, the tip amount is the cost times 0.xx and your total including tip, is the cost times 1.xx where xx = the percent you want to leave. If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip. If you want to leave a 18% tip, multiply the cost by 0.18 to get the tip amount or multiply the cost by 1.18 to get the total including tip.
Let's say you and a friend had dinner that cost $26.50. You had good service and want to leave an 18% gratuity. Put the percentage in decimal form (0.18) then multiply the cost by this number.
26.50 * 0.18 = 4.77. So your tip is $4.77.
An easy way to get the total amount, dinner plus tip, is to multiply the total by 1.18. 26.50 * 1.18 = 31.27. This works mathematically because you want to know your original cost plus the tip which is written as 26.50 + (26.50 * 0.18) = ? Factoring out the 26.50 from this equation you get 26.50 * (1 + 0.18) = 26.50 * 1.18.
How to calculate a tip in your head
You can get a good approximation of a tip by doing it in your head this way.
You can find 10% of your bill by moving the decimal one place to the left. If 26.50 is 100% then 10% is 2.65. Since 20% is 2 times 10%, 20% of the bill is 2.65 + 2.65 = 5.30. Now you know the tip you could leave ranging from poor to good, $2.65 to $5.30. To find 15%, halfway in between, we know 15% is 10% plus 1/2 of 10% (5%). 2.65 plus about 1.30 is 3.95.
Now you have
10% is 2.65 - by moving decimal 1 place left
15% is 3.95 - 10% + 1/2 of 10%
20% is 5.30 - 10% * 2
This is plenty of information to make a good guess at the tip amount you should leave. If you decide on about 18%, 4.50 to 5.00 would be a safe guess.

Answer:
19.5°
Step-by-step explanation:
The sum of any 3 angles of a triangle is 180.
That being so 33.5 + 127 + F = 180.
33.5 +127 + F - 33.5 = 180 - 33.5
127 + F = 146.5
127 + F - 127 = 146.5 - 127
F = 19.5
