When dividing fractions, the divisor must be inverted then multiplied with the other fraction?

1 answer:

5 0

Yes. That statement is true.

For example in : (1/2) divided by (3/4), you would invert 3/4 to make 4/3 and change the divide symbol to the multiply symbol. Becoming:

(1/2) multiplied by (4/3) = (1/2) divided by (3/4) = 0.66r

The probability of getting a 6 after rolling a fair dice 16.

Butoxors [25]

Answer:

P(6) = 5

Step-by-step explanation:

The dice is cast 30 times (k = 30)

So if the big numbers apply, then you would expect the outcome to be evenly distributed, meaning

5 x 1

5 x 2

5 x 3

5 x 4

5 x 5

5 x 6

____ +

30 casts in total (evenly distributed over all numbers of the dice)

P(6) = 1/6 * 30

P(6) = 5

Simplify. √20⋅√3·√18 5√30 5√10 6√10 6√30

ddd [48]

The correct answer is: [D]: " 6√30 " .

_____________________________________

Explanation:

_____________________________________

Simplify: " √20 ⋅ √3 · √18 " :

___________________________

Step 1) Simplify the "first term" :

"√20 " = √4 √5 = 2√5 ;

___________________________

Step 2): Consider the "second term:

"√3 " = √3 (already simplified);

___________________________

Step 3) Simplifly the "third term" :

" √18 " = √9 * √2 = " 3√2 " ;

____________________________

We have: " 2√5 * √3 * 3√2 " ;

= (2* 3) * (√5 * √3 * √2) ;

= 6 * (√5 √3 √2) ;

Note: " (√5 * √3 * √2 )" = " √(5 * 3 * 2) " = " √ 30 " .

So: " 6 * (√5 * √3 * √2) =

______________________________________

→ " 6 √30 " .

______________________________________

The answer is: " 6√30 " ;

→ which is: "Answer choice: [D]: " 6√30 " .
