In science class, Jada uses a graduated cylinder with water in it to measure the volume of some marbles. After dropping in 4 marbles so they are all underwater, the water in the cylinder is at a height of 10 milliliters. After dropping in 6 marbles so they are all underwater, the water in the cylinder is at a height of 11 milliliters.

What is the volume of 1 marble?
How much water was in the cylinder before any marbles were dropped in?
What should be the height of the water after 13 marbles are dropped in?
Is the volume of water a linear relationship with the number of marbles dropped in the graduated cylinder? If so, what does the slope of the line mean? If not, explain your reasoning.

Answers

1) 1ml % 6 marbles = about 0.17ml so the volume per marble is 0.17ml 2) 10-(0.17x4) = 9.32 so that is the original volume 3) then 9.32 + (0.17 x 13) = 11.53ml 4) it is linear because for every marble placed inside the cylinder the volume increases by about 0.17ml the slope means amount of marbles placed vs. volume in cylinder
Answer:
0.5
Step-by-step explanation:
4 marbles its at 10 and after dropping in 2 more its volume increased by one mL. and 1 divided by 2 equals 0.5.

P is the variable so put 100 under it

Then on the first empty fraction put 17/40

Cross multiply

You will get 40p=17x100

So then you multiply 17 by 100

1700

divided both sides by 40

Get the variable alone

Divide 1700 by 40

get 42.5

Answer:

17 feet

Step-by-step explanation:

The structure is shaped as a right triangle.

Use the Pythagorean theorem to solve for 'c' or the hypotenuse.

[tex]a^2+b^2=c^2\\\\8^2+15^2=c^2\\\\64+225=c^2\\\\289=c^2\\\\\sqrt{289} =\sqrt{c^2}\\\\17, -17 = c\\\\\text{Disregard negative value.}\\\\\boxed{17=c}[/tex]

The hypotenuse should be 17 feet.

Hope this helps!

Answer: 17 ft.

Step-by-step explanation: By using the pythagorean theorem (a^2 + b^2 = c^2) for right triangles, you should be left with the given equation after plugging in the values of the legs:

8^2 + 15^2 = c^2

Now simplify the squares

64 + 225 = 289 (c^2)

Now to find the exact value of the hypotenuse (c), square root the value of c^2.

√289 = 17

The hypotenuse of the triangles is 17 ft.

I know for me it hasnt been that long ago. But we also like judging pictures too right? Well I bet I can judge a movie clip and a picture and compare the two. I will be comparing a picture of the balcony scene from romeo and juliet and a movie clip of the romeo and juliet balcony scene. I honestly think that the movie clips were more useful The movie clips that were played out from Shakespeare's script were pretty tremendous I must say. The acting was almost like if the story was not written by Shakespeare and instead was recorded by him. But the picture doesn't have Romeo in it. It also doesn't have words so if someone saw it for the first time not knowing that it was Juliet and the balcony scene then they would not think of it as Juliet in the balcony.In other words, the video clip gives you more explanation because there is feeling and changed emotion and there are also words that back up those emotions. On the other hand for the picture, there are only lines and curves and it's just a drawing although it does show a romantic feeling we dont know this for sure but the roses do symbolize Romeo when it comes to the picture.
