What's the circumference of a
circle with a diameter of 31 inches?
Use 3.14 for pi.
Answers
Answer:
circumference = 97.34
Step-by-step explanation:
circumference = diameter x Pi
31 x 3.14 = 97.34 inches
The circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.
The circumference of a circle can be calculated using the formula C = πd, where C represents the circumference and d represents the diameter of the circle.
Given that the diameter of the circle is 31 inches, we can substitute this value into the formula:
C = 3.14 * 31
C ≈ 97.34 inches
Therefore, the circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

Yes, the triangles are similar to each other by AA rule and EF = 8.
What is similarity in triangles?When two triangles have congruent corresponding angles and corresponding sides in equal ratio, then they are said to be similar.
Given are the triangles, Δ ABC and Δ DEF,
In Δ ABC,
∠A + ∠B + ∠C = 180°
∠B = 180°- (60°+20°)
∠B = 100°
In Δ DEF,
∠D + ∠E + ∠F = 180°
∠F = 180° - (60°+100°)
∠F = 20°
∠A ≅ ∠D
∠B ≅ ∠E
∠C ≅ ∠F
We see, all the corresponding angles are congruent.
Therefore, according to definition of similar triangles Δ ABC ~ Δ DEF,
And,
AB/DE = BC/EF = AC/DF = 3/4
BC/EF = 3/4
6/EF = 3/4
EF = 8
Hence, the triangles are similar to each other by AA rule and EF = 8.

You picked two marbles from a bag and record their color. How can you make your selections independent events? Dependent events?
Answers
Answer:
Let's suppose the next case:
We have a bag, where there are 5 red marbles, and 5 blue marbles.
We have a total of 10 marbles.
Suppose that we pick a marble and we do not replace it, and suppose that the first one is a red marble.
Then now we have in the bag a total of 4 red marbles and 5 blue marbles.
Now let's find the probability of picking a blue marble, this will be equal to the quotient between the number of blue marbles (5) and the total number of marbles (9)
P = 5/9
Now, suppose that instead of a red marble in the first pick, we had a blue marble.
Then now we have 4 blue marbles and 5 red marbles in the bag.
Again, the probability of picking a blue marble will be equal to the quotient between the number of blue marbles (4) and total numbergof marbles (9)
P = 4/9
Then the first pick does affect the probabilities for the second pick, this means that if we do not replace the first marble we pick, then the events will be dependent.
Now, if we replaced the first marble we picked (we put it again in the bag) then the number of blue marbles and red marbles is always the same, then in this case bot events will be independent (the first event will not affect the second event)

Answers
There is a linear relationship between the variables x and y. And the line that passes through the origin. Then the correct option is C.
What are ratios and proportions?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Let the two variables x and y.
Where x is an independent variable and y is the dependent variable that depends on x directly. Then we have
The variable y is directly proportional to the variable x.
y ∝ x
When the proportionality sign is removed a constant k comes into the equation. That is given as
y = kx
There is a linear relationship between the variables x and y.
And the line that passes through the origin.
The graph is shown below.
