all you have to do is divide the top number by the bottom! ❤️ 45 / 50 = 0.9. 0.9= 90%

%90

Step-by-step explanation:

Since a percentage is out of 100 just multiply 50 times 2 and do the same to the top which would be 90

Which expression is equivalent to ? Assume.
nikdorinn [45]

Answer:

2. -2x^{8}y^{18}  

Step-by-step explanation:  

We have been given an expression \frac{10x^{6}y^{12}}{-5x^{-2}y^{-6}} and we are asked to find equivalent expression to our given expression.

Using fraction rule \frac{a}{-b} =-\frac{a}{b} we can write our expression as: -\frac{10x^{6}y^{12}}{5x^{-2}y^{-6}}. 

Upon dividing 10 by 5 we will get,

-\frac{2x^{6}y^{12}}{x^{-2}y^{-6}}      

Upon using exponent property for quotient (\frac{a^{m}}{a^{n}} =a^{(m-n)}) we will get,  

-\frac{2x^{6}y^{12}}{x^{-2}y^{-6}}=-2x^{(6--2)}y^{(12--6)}    

-2x^{(6+2)}y^{(12+6)}

-2x^{8}y^{18}        

Therefore, our expression simplifies as -2x^{8}y^{18} and 2nd option is the correct choice.

What is the probability of all cogs being defective
Sonbull [250]

Prob (first defective) = 4 / 20 = 1/5

Prob(2nd defective) = 3/19

Prob (3rd defective) = 2/18 = 1/9

Pron 4th defective) = 1/ 17

Prob ( all 4 defective) = 1/5 * 3/19 * 1/9 * 1/17 = 1 / 4845 answer

2х - Зу = 32<br> x + 4у = -20<br><br><br> solve the system of equations
ANTONII [103]
Answer: x=68/11 and y=-72/11


Steps:

2(x+4y=-20)

2x+8y=-40

2x - 3y = 32
- 2x + 8y = -40

-11y=72

y=-72/11


x + 4(-72/11) = -20

x - 288/11 = -20

x=68/11

I believe he is correct because you add/subtract from left to right, hence

6-2 comes first.
