Unlike Abby, I actually did more math then just adding up all the numbers. It will be a 40% chance to pull out a yellow marble, not a blue one. The correct answer is A, 30%. 30% times 40(marbles) = 12(number of blue marbles). So the answer is A, 30%. I would really appreciate it if you have me brainliest, knowing that I actually got you the right answer and didn’t just add.

How many lots of 10 second are there in 10 minutes
Vlad [161]

Answer:

60

Step-by-step explanation:

We can easily solve this by finding out how many 60 seconds are in 10 minutes, and then dividing by 10.

To do that, multiply 60 seconds by 10, since there are 60 seconds in each minute.

60*10=600. There are 600 seconds in ten minutes.

Now, divide by 10.

600/10=60

There are 60 intervals of 10 seconds in 10 minutes.

Hope this helps!

Choose the point-stope form of the equation below that represents the line that passes through the point (-1, 6) and has a slope
Keith_Richards [23]

Answer:

y-6 = -3(x+1)

Step-by-step explanation:

The point-slope form of a line is the following:

y-yo = m(x-xo), where 'm' is the slope and (xo, yo) is any point where the line passes through.

In this case, m=-3 and (xo, yo) = (-1, 6).

Therefore: y-yo = m(x-xo) = y-6 = -3(x+1)

In conclusion, the point-slope form of the equation that represents the line that passes through the point (-1, 6) and has a slope of -3 is:

y-6 = -3(x+1)

Use the function to answer the question f(x)=-2|x-5|+3 what is the vertex of the graph of f(x)
Dennis_Churaev [7]

Answer:

The vertex of this graph is (5, 3)

Step-by-step explanation:

In order to find the vertex of any graph in vertex form, we need to look at the base form.

f(x) = a|x - h| + k

The point (h, k) is the vertex. You can see that 5 lines up with the h term and 3 lines up with the k term. This gives us a vertex of (5, 3)
