STEP 1:
Add the number of total students
= 27+25+23
=75

STEP 2:
Find the percentage that 18 out of 75 students is.

18/75=x/100

cross multiply
(18*100)=(75*x)

1800=75x
divide both sides by 75
24%=x

Check:
75 * 24%= 18

Hope this helps! :) Good luck!

Answer:

Position of the submarine now relative to the water surface $=-47\ \frac{3}{4}$

Step-by-step explanation:

It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.

Now we need to find about what is the position of the submarine now relative to the water surface.

Downward navigation means we 15 1/2 is negative

so we will just add both values to get the final answer:

Position of the submarine now relative to the water surface = $-32\ \frac{1}{4}-15\ \frac{1}{2}$

$=-32\ \frac{1}{4}-15\ \frac{2}{4}$

$=-47\ \frac{3}{4}$

If you reflect any shape across the x-axis and then across the y-axis, do you get the same result that you would if you rotated

Anton [14]

Yes, it has the same result

look at the picture. the red triangle is the first image. the green one is the result of reflecting over x-axis. then if you reflect it over y-axis, it would be the purple triangle

if you had rotated the red triangle at first, it would have the same result

good luck
