Answer:

1/12

Step-by-step explanation:

There is only number between 1 and 12 that is both a multiple of 5 and 2, that being 10. 10 has an equal chance out of all the other numbers that can be spun, and there are 12 numbers, so 10 has a 1/12 chance of being spun.

Answer:

This would be if we are finding the altitude of the submarine from the surface of the water(how many meters away from the surface it is). I don't know what it would be if you want to know from the bottom of the ocean.

A student answers

Marina CMI [18]

So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27

To find the number of questions in the exam, make an equation
(90% = $\frac{90}{100}$ = 0.9)
$\frac{90}{100}$ = $\frac{27}{x}$
cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer
$\frac{90x}{90} = \frac{2700}{90}$
90 and 90 cancels out
x = 30
So your final answer will be, there were 30 questions in the exam paper.
