Typically cylinder was graduated in mL

The volume of the metal is indicated by how much the water level rises in the cylinder.

Volume of metal = New level - Initial level = 70 - 50 =20 mL

Density = Mass / Volume

              =  140 g / 20 mL

              =  7 g/mL

Density of the metal = 7 g/mL

Note that 1 mL = 1 cm³.  Therefore 7g/mL = 7 g/cm³.

Density = 7g/mL or 7 g/cm³.

I hope this helps.

The density would be 7g/ml.

DedPeter [7]

Answer:

32$ < x < 48$

Step-by-step explanation:

Erika estimates that her destination is between 200 and 300 miles away.

When we divide 200 with 25 miles we get 200/25 = 8 gallons

When we divide 300 with 25 miles we get 300/25 = 12 gallons

When we multiply 8 · 4 = 32$ we get amount of money for destination

200 miles  x = 32$

When we multiply 12 · 4 = 48$ we get amount of money for destination

300 miles  x = 32$

Since that the estimate destination is between 200 miles and 300 miles

then the best estimate for the amount of money is between

32$ < x < 48$

God with you!!!

Simplify the following expression.<br><br><br> A. <br><br> B. <br><br> C. <br><br> D.
Dahasolnce [82]

Answer:

D

Step-by-step explanation:

Let's start by crossing everything out!

12/3 can be crossed out to 4.

a^3/a^2 can be crossed out to a.

b^6/b^4 can be crossed out into b^2.

c^5/c^5 is just 1.

So which the results we got, we can multiply them, so that it is 4ab^2.

4ab^2 is our final answer!

Which is a counterexample for the conditional statement shown?
Arte-miy333 [17]

Answer: First Option

<em>The points have the same x-coordinate value.</em>

Step-by-step explanation:

By definition, a relation is considered a function if and only if for each input value x there exists <u><em>only one </em></u>output value y.

So, the only way that the line that connects two points in the coordinate plane is not a function, is that these two points have the same coordinate for x.

For example, suppose you have the points (2, 5) and (2, 8) and draw a line that connects these two points.

The line will be parallel to the y axis.

Note that the value of x is the same x = 2. But when x = 2 then y = 5 and y = 8.

There <u><em>are two output</em></u><em> </em>values (y = 8, y = 5) for the same input value x = 2.

In fact all the vertical lines parallel to the y-axis have infinite output values "y" for a single input value x. Therefore, they can not be defined as a function.

<u>Then the correct option is: </u>

<em>The points have the same x-coordinate value.</em>
