The answer is 7 meters.
Area is (pi)r^2
If we remove pi, we have 49=r^2
This means that r=7
Answer:
11 units apart
Step-by-step explanation:
You have to count how many units are in between A and B
Answer:
Each person will get $2.66 back.
Step-by-step explanation:
First you multiply 5 by 10 because there are a total of 5 friends that will pay $10 each.
You now have $50 which is all of the money of the friends combined.
The bill was $36.70 So you will need to subtract the bill from the money that the friends put in ($50-36.70) Which leaves the friends with $13.30 in left over change.
You now need to disperse the left over change amoung the 5 friends.
$13.30 devided by 5 is $2.66
Each friend will get $2.66 in change back.
Answer: y = x
<u>Step-by-step explanation:</u>
First, find the point where 5x - 2y + 3 and 4x - 3y + 1 intersect using the Elimination Method.
5x - 2y + 3 = 0 → 3(5x - 2y + 3 = 0) → 15x - 6y + 9 = 0
4x - 3y + 1 = 0 → -2(4x - 3y + 1 = 0) → <u> -8x + 6y - 2</u> =<u> 0 </u>
7x + 7 = 0
7x = -7
x = -1
5x - 2y + 3 = 0
5(-1) - 2y + 3 = 0
-5 - 2y + 3 = 0
-2y - 2 = 0
-2y = 2
y = -1
(-1, -1)
Next, find the point where x = y and x = 3y + 4 intersect using the Substitution Method.
x = y
x = 3y + 4 → y = 3y + 4
-2y = 4
y = -2
x = y
x = -2
(-2, -2)
Now, find the line that passes through (-1, -1) and (-2, -2) using the Point-Slope formula. (x₁, y₁) = (-1, -1) and m = 1
y - y₁ = m(x - x₁)
y + 1 = 1(x + 1)
y = x
Answer:
5
Step-by-step explanation:
Among the 20 digits shown, each digit appears in the list twice except 0 and 1 appear 3 times and 6 and 9 appear once. That means ...
- 1 appears 3 times
- 2 appears 2 times
So, if 1 and 2 represent red candies, there are 3+2 = 5 red candies in the simulated random sample of 20 candies.

<em>Comment on the question</em>
The simulation makes sense only if it represents taking a single candy from each of 20 packages (of unknown quantity of candies). That is, it seems we cannot answer the question, "how many red candies will be in the packages?" We can only answer the question, "how many of the simulated candies are red?"
