hannah says that 1/8 is not on the number line and cannot be plotted. write a note to hannah about her misunderstanding

ad-work [718]

Answer and explanation :

Hannah said that $\frac{1}{8}$ is not on the number line but she is wrong because $\frac{1}{8}$ can be represented on the number line

When we convert the fraction $\frac{1}{8}$ into decimal then it is equal to 0.125

And 0.125 lies between 0 and 1

If we divide one unit on number line into 10 parts then 0.125 lie between 0.1 and 0.2

And we know that any real number can be represented on number line as 0.125 is a real number so it can be represented on the number line

What is the solution of the system of equations?<br> 4x-8y=0<br> 5x+2y=6

katrin [286]

Answer:

x=1,

y=1/2

Step-by-step explanation:

4x-8y=0

so 4x=8y

x=2y

5x+2y=6

because x=2y

so:

5x+x=6

6x=6

x=1;

then

x=2y

1=2y

y=1/2

I don’t know how to do this. HELP!

Karo-lina-s [1.5K]

Answer:

1/4

Step-by-step explanation:

coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.

The area of the square base is S(x), where x is the length of the concrete foundation, and the area of the base of the cylindric

Andrews [41]

Answer:

C(r) is the area of the base of a cylindrical tank with radius r.

We know that this area is:

C(r) = pi*r^2

S(x) is the area of the square base where x is the side length of the base.

S(x) = x*x

Now, we have the expression:

S( C(r)) wich means that we are evaluating the function S(x) in the point x = C(r)

Now, we have a problem here.

In S(x), S(x) is in units of area, and x is in units of length.

And the same for C(r), C(r) is in units of area, and r in units of length.

then we can not have x = C(r)

Then this expression does not represent anything, because the units do not match, so it has no physical sense.
