18 students are 100%-37,5%-40%=22,5%
So we know that 18 students equal to 22.5. And we are looking for the anwser what 100% of students is. 
SO:
x students - 100%

(22 + 1/2)x =18×100

(22 + 1/2) can be represented as just 25.5

-//- = 1800

we need to divide bot sides by 25.5

x = 1800 / 25.5
... x = 80

I need help with question 9 please!
ankoles [38]
The answer is A. 20 you know that the equation plus the angle that equals 46 are equal to 90 degrees so..... use the formula  
2x+4+46=90

simplify by adding 4 and 46
2x+50=90
subtract 50 from both sides
2x=40
divide each side by 2
x=20

and that's how you get your answer

How are the power rules for quotients and products similar? How are they different? Refer specifically to the way that the rule
Lady_Fox [76]
Power rules for both quotient and product sums are useful to simplify large exponential form (of the same base)

The difference is in the rule. For quotient sum, the powers are subtracted, while for product sum, the powers are added up.

An example for quotient sum
\frac{7^{13} }{7^{8} } = \frac{7*7*7*7*7*7*7*7*7*7*7*7*7}{7*7*7*7*7*7*7*7*7*7}
Using the principle of simplifying fractions, we can cancel out ten 7s from both numerator and denominator, leaving us with only three 7s on the numerator which gives us 7^{3}. This working out could be simplified by doing 7^{13-10}= 7^{3}

An example for product sum
9^{5}* 9^{6} =(9*9*9*9*9)*(9*9*9*9*9*9)= 9^{11}. There is a total of eleven 9s if we were to work out the product sum the long way. This could be simplified by doing 9^{5+6} = 9^{11}
