Answer:

DE = 10

Step-by-step explanation:

<h3>Given</h3>

B C : C D : D E = 1 : 6 : 2
BE = 45
DE = ?

<h3>Solution</h3>

BC = x, CD = 6x, DE = 2x
BE = BC + CD + DE
x + 6x + 2x = 45
9x = 45
x = 5
DE = 2x = 2* 5 = 10

Which of the tables represents a function?

Damm [24]

Input is domain and output is co-domain.
An expression is said to be a function if for every input, there is only one output. In table B, for every input, you get different outputs. Therefore, table B is a function.

What is the probability that a marble chosen at random is

Brums [2.3K]

Answer:

$P=\frac{6}{11}$

Step-by-step explanation:

The probability can be defined as the ratio between the possible events and the total number of outcomes.

In this case, according to the image attached, the total number of outcomes is 11, because they are 11 marbles in total.

Now, the specific event is all shaded marbles or labeled with a multiple of 3. With this specific characteristics 6 marbles, because there are 5 shaded marbles and 6 is a multiple of 3. So, the possible events are 6.

Therefore, the probability is

$P=\frac{6}{11}$

The right answer is the last choice.

Adriano runs a website that helps writers write better stories. Every month, Adriano receives a subscription fee of $5 from each

tatuchka [14]

There aren't really any instructions for this, so I'll just go ahead and find the total amount of money for both months. The first month Adriano had 200 subscribers. 5 times 200 is 1000, so Adriano received $1000 that month. The second month 40 members joined, but 10 cancelled their subscription. Taking this into account, we'll just say that 30 members joined. 30 times 5 is 150, and 150 plus 1000 is 1150. Therefore, Adriano had to have received $1150 the second month.

I'm not entirely sure what the question was to begin with, but I hope this answers it!
