If you divide the mass of a substance by its volume, can you can find its density?

Answers

Answer 1

Answer: So the question is is it true or false that when you divide the mass of a substance by it's volume you will get its density. So from the definition of density we know that density=mass/volume or: D=m/V. So the answer is true, when you divide a mass of a sbstance by its volume, you get it's density.

What value of x makes the equation true? PLZ HELP RIGHT THANK YOU

–7.12 = –4.8 + x

A.

–11.92

B.

–11.2

C.

–2.32

D.

2.32

Answers

so just remember tha tyou can do anything to an equation as long as you do it to both sides (except divide by 0) so
-7.12=-4.8+x
add 4.8 to both sides since -4.8+4.8=0 so it cancels
4.8-7.12=x
simplify
4.80-7.12=-2.32
-2.32=x
the naswer is C

-7.12 = -4.8 + x

-7.12 = x - 4.8

Add 4.8 on both sides

x = -7.12 + 4.8

x = -2.32

Your final answer is C. -2.32.

Angelica is working on function machines. She has two machines g(x)=square root x-5 and h(x)= x^2-6. she wants to put them in order so that the output of the first machine becomes the input of the second. she wants to use a beginning input of 6.a) in what order must she put the machines to get a final output of 5.
b)is it possible for her to get a final output of -5? if so,show how she could do that. If not explain why not.

PLEASE HELP!

Answers

$g(h(x))=√(x^2-6-5)=√(x^2-11)\ng(h(6))=√(6^2-11)=√(36-11)=√(25)=5$

a)
$h(x)$ is the input for $g(x)$ , so $h(x)$ must be first

b)
It's impossible for $g(h(x)=√(x^2-11)$ , because its value is always non-negative for any x. Let's see what about $h(g(x))$ .

$h(g(x))=(√(x-5))^2-6=x-5-6=x-11$

The result is a non-constant linear function, so its value can be any real number, including -5. You can calculate for what x it's equal to -5.

$x-11=-5\nx=6$

$x-11=-5\nx=6$

a) To get a final output of 5 , she must first input 6 into machine h(x) , then the result from machine h(x) is input back to machine g(x).

b) It is possible to get a final output of -5. It could be done by first input 6 into machine g(x) , then the result from machine g(x) is input back to machine h(x).
