C. The answer is C because the total amount of students is 14, and there are 4 boys, which makes the ratio 4 boys to 14 students in total. 4 and 14 are both divisable by 2, so divide 4 to get 2 and divide 14 to get 7. This leaves you with 2 and 7. The ratio would be 2 boys to 7 total students. Hope this helped

Answer: 50 holes
Step-by-step explanation: I find an easy way to answer questions like this is by 'dimensional analysis'....
Dimensions mins/holes and mins
mins / (mins/holes) = holes (because 'mins' cancel out)
25 mins / (6 mins/12 holes) = 300/6 holes = 50 holes
Answer:
2
Step-by-step explanation:
let the other leg be x
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 3²
x² + 1 = 9 ( subtract 1 from both sides )
x² = 8 ( take the square root of both sides )
x = 
= 
= 
× = 2 ← exact value
X= 3/13. First you need to combine like terms, which would make 13x, and your equation would be 13x=3. then divide both sides by 13 and your X equals 3/13.
