Answer 2
Answer:

Answer:

2400 milligrams because 480 is 20% of the recommended amount

Step-by-step explanation:

Rewrite equation in vertex form y=x^2+4x+2

Answers

Answer: y =(x+2)^2-2

Steps:

The general vertex form of a parabola is as follows:

y = a(x-x_v)^2+b

where xv is the x coordinate of the vertex, a is the coefficient determining how wide/narrow the parabola is and whether it is open-up (+) or open-down (-), and b is the bias (vertical shift.


Transforming an expression into the vertex form involves completing the square step:

y=x^2+4x+2\ny = x^2 + 2\cdot2 x+ 2 + 4 - 4= (x+2)^2-2\ny =(x+2)^2-2\n\implies x_v = -2,a=1, b=-2

PLEASE HELP! WILL CHOOSE THE BRAINLIEST ANSWER!!Mark has 100 blue marbles, 34 red marbles, and 98 green marbles. After pulling out 6 blue marbles, 3 green marbles, and 1 red marble, he add's 20 pink marbles. What is the probability that he will pull out a pink marble?

Answers

Mark started out with 232 marbles in the bowl. He pulled out 10 of them, leaving 222 marbles in the bowl. Then he added some. Now there are 242 marbles in the bowl, and 20 of them are pink. The probability that his next pull will be a pink one is 20/242 = about 8.3 percent.

The probability of Mark pulling out a pink marble is approximately 0.083 or 8.3%.

To find the probability of pulling out a pink marble, we need to know the total number of marbles Mark has after making the changes described in the problem.

Mark started with a total of 100 + 34 + 98 = 232 marbles.

After pulling out 6 blue, 3 green, and 1 red marble, he has 100 - 6 = 94 blue marbles, 34 - 1 = 33 red marbles, and 98 - 3 = 95 green marbles left. This means he has a total of 94 + 33 + 95 = 222 marbles.

When he adds 20 pink marbles, his total number of marbles becomes 222 + 20 = 242.

So the probability of pulling out a pink marble is:

Number of pink marbles / Total number of marbles = 20/242 ≈ 0.083

Therefore, the probability of Mark pulling out a pink marble is approximately 0.083 or 8.3%.

If the bases and heights of a prism and a pyramid are the same and the volume of the prism is 27 cubit units, what is the volume of the pyramid? cubic units

Answers

Answer:

The volume of the pyramid is 9 cubic units.

Step-by-step explanation:

Given : If the bases and heights of a prism and a pyramid are the same and the volume of the prism is 27 cubit units.

To find : What is the volume of the pyramid?

Solution :

We know that,

If a pyramid and a prism have the same base and height then their volumes are always in the ratio of  1 : 3.

Which means the volume of pyramid is one-third of the volume of the prism.

i.e.V_P=(1)/(3)* V_p

Volume of the prismV_p=27 \text{ unit}^3 (given)

The volume of pyramid is

V_P=(1)/(3)* 27

V_P=9\text{ unit}^3

Therefore, The volume of the pyramid is 9 cubic units.
You divide 27 with 3 I think, because when you need to know the pyramid's volume you do:
base x height / 3
And when you want to know the prism's it's just the base x height.
