The third one is the answer

Studentka2010 [4]2 years ago

3 0

Answer:

the 3rd one

Step-by-step explanation:

3/7 * 8 = 24/7

24 can be divided by 7 three times.

7 * 3 = 21

We still have 3/7 left over. Make it a mixed number.

3 3/7

Two passenger trains 190 miles apart are headed toward each other on the same track—one at 50 mph and the other at 80 mph. Ironm

frozen [14]

190-(50+80)t=0

190-130t=0

130t=190

t=19/13 so the trains will remain apart for 19/13 hours.

Since ironman is flying at a constant rate of 150mph he will fly:

150(19/13)≈219.23 miles in that time period while the trains are apart.

What is the answer to this?

Vinvika [58]

9514 1404 393

Answer:

see attached

Step-by-step explanation:

A function can have only one output for any given input. Thus for the repeated input, the function will have the same output repeated.

A non-function will have two (or more) different outputs for one input. So, for the repeated input, the non-function will have different outputs. (Anything that is not 6 will do.)

Find sin 0, where is the angle shown. Give an exact value, not a decimal approximation.

Nata [24]

Answer:

$\displaystyle \sin\theta=\frac{12}{13}$

Step-by-step explanation:

Recall that in a right triangle, sine is the ratio of the opposite side to the hypotenuse:

$\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$

We are actually not given the opposite side in this case. However, since we know the hypotenuse and the adjacent side, we can use the Pythagorean Theorem to find the opposite side. So:

$a^2+b^2=c^2$

Let a be the adjacent side and b be the opposite side. c will be the hypotenuse.

Substitute:

$(5)^2+b^2=(13)^2$

Solve for b:

$b=\sqrt{169-25}=\sqrt{144}=12$

So, the opposite side measures 12.

Then sine will be:

$\displaystyle \sin\theta=\frac{12}{13}$

Which two representations are considered to be only partial representations?

DaniilM [7]

Answer:

D) The graph and the table

Step-by-step explanation:

The equation and the verbal description fully represent the situation because their representation is valid for all possible x values. On the other hand, the table and the graph only represent certain x values.
