A rock has a density of 4.56 g/mL. If it weighs 235 g, what is its volume?

Answers

Answer:

51.54mL

Step-by-step explanation:

Density can be defined as the mass per unit volume of a particular object , substance or compound.

Density tell us how heavy or dense that object, substance or compound is.

Mathematically, the formula for Density = Mass(grams)/Volume(ml or cm³)

In the above question, a rock has the following criteria:

Density = 4.56 g/mL.

Mass = 235 g

Volume is unknown.

Imputing this values into the formula for Density, we have:

4.56g/mL = 235g/ Volume

Cross Multiply

4.56g/mL × Volume = 235g

Volume = 235g/4.56g/mL

Volume = 51.535087719mL

Approximately, the volume of the rock to 2 decimal places = 51.54mL

To simplify this expression, we combine all the like terms. We cannot solve for x because there is no equal sign and/or no value for x.

Equation: (10x² - 10x - 6) + (x + 6)

[tex]\bf Step~1:[/tex]

-10x and x are like terms. Remember: there is an invisible 1 behind the variable x. We add these like normal numbers.

[tex]\bf -10x+1x=-9x[/tex]

[tex]\bf Step~2:[/tex]

-6 and 6 are also like terms. Again, we add them as written.

[tex]\bf -6+6=0[/tex]

Since our answer is 0, we do not have to write it in our simplified expression.

[tex]\bf Step~3:[/tex]

Now, let's add the terms together. Since 10x² doesn't have any like terms, we just let it be. We take our previous number, -9x, and we add it to 10x².

[tex]\bf 10x^2+-9x[/tex]

Point Fis on line segment EG . Given FG = 4 and EF = 9 determine the length EG

Answers

Answer:

EG is 13.

Step-by-step explanation:

So we have a line segment EG.

Point F is somewhere on EG.

And we are given that FG is 4 and EF is 9.

Therefore, the length of EG will be the combined lengths of FG and EF. In other words:

[tex]EG=EF+FG[/tex]

Substitute 9 for EF and 4 for FG. Thus: "

[tex]EG=9+4[/tex]

Add:

[tex]EG=13[/tex]

So, the length is EG is 13.

And we're done!

To set this up you will set the two angles equal to 180° since it is a straight line
This will make the equation x+6x+19=180
Combine like terms. 7x+19=180.
Subtract 19 from both sides. This will make it 7x=161
Divide both sides by 7. That will make it x=23
Next plug in the x to solve for abc. 7(23)+19. This equals 157

X= 23

The picture shows the Alamillo bridge in Seville, Spain. In the picture m<1=58 and m<2=24. Find the measure of the supplement of <1= and of <2. Someone please help!

Answers

Answer:

Supplement of <1 = 122°

Supplement of <2 = 156°

Step-by-step explanation:

Two pairs of angles are said to be supplementary, if their measures in degrees add up to give us 180°. A supplement of am angle is simply 180° - the measure of that angle.

Given that meadure of angle 1 = 58°, the supplement of angle 1 = 180° - 58° = 122°

Also, if the measure of angle 2 = 24°, the supplement of angle 2 = 180° - 24° = 156°.

Thus:

Supplement of <1 = 122°

Supplement of <2 = 156°

Answers

Answer:

I feel like its that but im rlly not sure.

Step-by-step explanation:

Leanne's list is incorrect and there are 3 different sides a person can choose. So, there are a total of 6 possible ways a person could choose their dinner.

How to determine the number of combinations?

The given parameters are:

Main Dish: B, C and P

Sides: A and F

Using the above parameters, the combination of dishes are:

BA, BF, CA, CF, PA and PF

Hence, we can conclude that Leanne list is incorrect

Also, we have:

Dish = 3

Sides = 2

So, the number of dinner to choose is:

Dinner = 3 * 2 = 6

Hence, a person could choose their dinner in 6 ways

Point B lies on AC between A and C. If AB = 8 and AC = 10, find BC.
A. 2
B. 8
C. 10
D. 18

Answers

Answer:

BC = 2

Step-by-step explanation:

If B lies on AC it makes the line segments AB and BC.

AC=10

AB+BC=AC

AB+BC=10

8+BC=10

BC=2

The value of BC is 2 which is the correct answer that would be an option (A).

What is a Line Segment?

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment AC , where the length of line segment AC refers to the distance between its endpoints, A and C.

Point B lies on AC between A and C.

A______________B______________C

Given that B lies on AC it makes the line segments AB and BC.

AB = 8 and AC = 10

⇒ AB + BC = AC

⇒ AB + BC = 10

⇒ 8 + BC = 10

⇒ BC = 2

Therefore, the value of BC is 2 which is the correct answer that would be an option (A).
