Answer:
C. The circumference of circle 1 is less than the circumference of circle 2.
Step-by-step explanation:
6<7
We know that the formula for the area of a circle is πr². This means the greater the radius, the greater the area.
We also know that the formula for circumference is 2πr. It is also dependent on radius. The greater the radius, the greater the circumference.
Given that Circle 2 has a greater area, this means that it has a greater radius which in turn means that it has a greater circumference.
C. The circumference of circle 1 is less than the circumference of circle 2.
Answer:
The circumference of circle 1 is less than the circumference of circle 2.
Step-by-step explanation:
Hi there!
When we compare two circles, if one is bigger than the other, it must have a greater circumference. We can see this visually.
If we want to prove this, we can take a look at the area and circumference formulas (r = radius):
[tex]A=\pi r^2[/tex]
[tex]C=2\pi r[/tex]
If we were to substitute the area formula into the formula for circumference, we would get the following:
[tex]\displaystyle\frac{A}{\pi}=r^2\\\\\sqrt{\displaystyle\frac{A}{\pi}}=r[/tex]
[tex]C=2\pi (\sqrt{\displaystyle\frac{A}{\pi}})[/tex]
Therefore, the greater the area of a circle, the greater its circumference.
I hope this helps!

How to find the area of a triangle: base times height divided by 2
The equation will be 6.8 times 6.4 divided by 2 = 21.76
This is the area of one triangle, there is 4 triangles
(6.8 from get this length from the square which has all four sides the same length)
There are 4 triangles, so times 21.76 by 4, to get 88.04
fianally, you get the area of a square by doing length times height
6.8 times 6.8 = 46.24
then all all the area together. 88.04+46.24=134.28

What is ∑n=16[4(−5)n−1] equal to?
Answer:
This will be the sum of a geometric series where the first term is 4
The common ratio is -5
And we will have 6 terms.....so....the sum is
first term [ 1 - common ratio^number of terms ] / [ 1 - common ratio ] =
4 [1 - (-5)^6] / [ 1 - -5 ] =
4 [ 1 - 15625 ] / 6 =

A password is to be made from a string of five characters chosen from the lowercase letters of the alphabet and the numbers 0 through 9.
Using the Fundamental Counting Theorem, it is found that for each case, the total number of outcomes is:
a) 60,466,176.
b) 5,961,600.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
Item a:
No restrictions, hence for each of the five characters, there are 36 outcomes, hence [tex]n_1 = \cdots = n_5 = 36[/tex].
Then, the possible number of passwords is:
[tex]N = 36^5 = 60466176[/tex]
Item b:
The letters and the digits have to be alternated, hence:
Starting with a letter, [tex]n_1 = n_3 = n_5 = 36, n_2 = n_4 = 10[/tex].Starting with a digit, [tex]n_1 = n_3 = n_5 = 10, n_2 = n_4 = 36[/tex].Then, the possible number of passwords is:
[tex]N = 36^3 \times 10^2 + 10^3 \times 36^2 = 5961600[/tex]

Jim started reading at 6:45. He read for 1 hour and 20 minutes. When did Jim stop reading?
Jim stopped reading at 8:05, after reading for 1 hour and 2 minutes when we started at 6:45.
How do we add time?In time problems, we need to know the relations between seconds, minutes, hours, and days.
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds.
How do we solve the given question?We are informed that Jim starts reading at 6:45.
He reads for 1 hour and 20 minutes.
We add this time to the time he starts reading to find the time when Jim stops reading.
First we add hours, 6 + 1 = 7 hours.
Now we add minutes, 45 + 20 = 65 minutes. But we know 60 minutes = 1 hour, so we can say 65 minutes = 1 hour and 5 minutes.
So when we calculate the total time, we get,
Jim stopped reading at 7 + 1:05 = 8:05.
∴ Jim stopped reading at 8:05, after reading for 1 hour and 20 minutes when we started at 6:45.

P( Drive to school | Sophomore ) = [?]
Answer:
P(Drive to school | Sophomore) = 0.07 (nearest hundredth)
Step-by-step explanation:
A probability is conditional if it depends on what has already happened.
P(Drive to school | Sophomore) means:
The probability that a student "drives to school" given that they are a "sophomore".
Using the conditional probability formula:
P(B | A) = P(B ∩ A) ÷ P(A)
⇒ P(Drive to school | Sophomore) = P(Drive to school ∩ Sophomore) ÷ P(Sophomore)
Reading from the two-way table, there are 2 people that drive to school AND are a sophomore.
Adding all the values in the table gives us the total number of students: 2 + 13 + 25 + 25 + 20 + 5 + 3 + 2 + 5 = 100
⇒ P(Drive to school ∩ Sophomore) = 2/100 = 0.02
Adding all the values in the sophomore line of the table gives us the total number of sophomores: 2 + 25 + 5 = 30
⇒ P(Sophomore) = 30/100 = 0.3
Now plug these values into the formula:
P(Drive to school | Sophomore) = P(Drive to school ∩ Sophomore) ÷ P(Sophomore)
P(Drive to school | Sophomore) = 0.02 ÷ 0.3
= 1/15
= 0.07 (nearest hundredth)

|2x + 11| =2(x + 1) solve the absolute value
Answer:
Step-by-step explanation:
|2x + 11| = 2(x+1) to find the absolute value we write two equations
2x + 11 = 2x + 2 or
2x + 11 = -2x - 2 for the first equation
2x + 11 = 2x + 2 export like terms to the same side of the equation
2x - 2x = 2 - 11
0 = -9 this expression is wrong now let's try second equation
2x + 11 = -2x - 2 export like terms to the same side of the equation
2x + 2x = -2 - 11
4x = -13 divide both sides by 4
x = -13/4

Answer:
The relationship in this equation is linear, but not proportional. If it was proportional, then replacing x with nx should give ny as the answer. Example:
y = 3x
Replace x with 2x.
y' = 3(2x) = 2(3x) = 2y
y' = 2y
This is proportional. But if you replace x with 2x in
y = 3x + 5,
you will not get 2y for y'. This case is not proportiona
Answer:
If two quantities are proportional, then they have a constant ratio. If the ratio is not constant, the two quantities are said to be non-proportional. We will make tables and look at the relationship between the variables to determine proportionality.
Step-by-step explanation:
If we were to graph this the vertices would be (0,5), (1,8) then after that the vertices are not constant therefore making it NOT a proportional relationship
y = 3x
Replace x with 2x.
y' = 3(2x) = 2(3x) = 2y
y' = 2y
This is proportional. But if you replace x with 2x in
y = 3x + 5,
you will not get 2y for y'. This case is not proportional

because it is
each day you terry and 3 other friends randomly choose one of your 5 names from a hat to decide who throws away everyone's lunch trash what is the probability that you are chosen on monday and terry is chosen on tuesday
1/5 because there is 5 friends and you will each have 1 percent of probabality.
The probability of being chosen on Monday is 1/5, and the probability of Terry being chosen on Tuesday is 1/4, the probability of both events happening is 1/20.
To find the probability that you are chosen on Monday and Terry is chosen on Tuesday,
Calculate the probability of each event separately and then multiply the probabilities.
Probability of you being chosen on Monday:
There are 5 names in the hat, including yours. Since you and 3 friends are drawing one name randomly, the probability of you being chosen on Monday is 1 out of 5.
Probability of you being chosen on Monday = 1/5
Probability of Terry being chosen on Tuesday:
After you were chosen on Monday, there are now 4 names left in the hat, and one of them is Terry's. So, the probability of Terry being chosen on Tuesday is 1 out of 4.
Probability of Terry being chosen on Tuesday = 1/4
Now, to find the probability of both events happening, we multiply the probabilities:
Probability of you on Monday AND Terry on Tuesday = (1/5) * (1/4) = 1/20
Therefore, the probability that you are chosen on Monday and Terry is chosen on Tuesday is 1/20.
