Answer: $0.25

Step-by-step explanation: If I read this correctly then, assuming each person gets or brought the same amount of money, they each brought 25 cents. 125/500 = 0.25

A pair of vertical angles has measures (3x+4)° and (7x-9)°<br> What is the value of x?

Andrei [34K]

Since they are vertical they are equal to each other.

3x + 4 = 7x - 9
4 = 4x - 9
13 = 4x
3.25 = x

So the value of x is 3.25.

Hope this helps :)

Evaluate the expression:<br><br> x^2+2x−xy when x = 250 and y = −120

NikAS [45]

Answer:

33000

Step-by-step explanation:

Substituting 250 for x and -120 for y, we get:

(250)^2 + 2(250) - (250)(120) = 62500 + 500 - 30000, or

32500 + 500, or 33000

Please explain the answer

Stella [2.4K]

Answer:

C. The average velocity of A is greater than B since it covers more distance.

Step-by-step explanation:

The y values on the graph represent velocity. Since A has a greater y-value than B for the entire 10 seconds, we know that the average velocity of A must be greater than B.

Can you please help me out

Taya2010 [7]

The bag contains,

Red (R) marbles is 9, Green (G) marbles is 7 and Blue (B) marbles is 4,

Total marbles (possible outcome) is,

$\text{Total marbles = (R) + (G) +(B) = 9 + 7 + 4 = 20 marbles}$

Let P(R) represent the probablity of picking a red marble,

P(G) represent the probability of picking a green marble and,

P(B) represent the probability of picking a blue marble.

Probability , P, is,

$\text{Prob, P =}\frac{required\text{ outcome}}{possible\text{ outcome}}$ $\begin{gathered} P(R)=\frac{9}{20} \\ P(G)=\frac{7}{20} \\ P(B)=\frac{4}{20} \end{gathered}$

Probablity of drawing a Red marble (R) and then a blue marble (B) without being replaced,

That means once a marble is drawn, the total marbles (possible outcome) reduces as well,

$\begin{gathered} \text{Prob of a red marble P(R) =}\frac{9}{20} \\ \text{Prob of }a\text{ blue marble =}\frac{4}{19} \\ \text{After a marble is selected without replacement, marbles left is 19} \\ \text{Prob of red marble + prob of blue marble = P(R) + P(B) = }\frac{9}{20}+\frac{4}{19}=\frac{251}{380} \\ \text{Hence, the probability is }\frac{251}{380} \end{gathered}$

Hence, the best option is G.
