Answer: 9
Step-by-step explanation:
let the two-digit number has the digit 'x' in ten's place and 'y' in one's place.
So, The Original Number will be 10x+y and the Reversed Number will be 10y+x.
Now, According to the given information :
⇒ 5(x+y) + 13 = 10x + y
⇒ 4y + 13 = 5x ......(equation 1)
and,
⇒ 4(x+y) + 21 = 10y + x
⇒ 6y - 21 = 3x ......(equation 2)
By solving equation 1 and 2, we get
y = 8 and x = 9
Hence,
The Original Number = 10x + y = 10×9 + 8 = 98
The Reversed number = 10y + x = 10×8 + 9 = 89
and,
The difference of the original two-digit number and the number with reversed digits is ( 98 - 89 ) = 9.
<u>Answer:</u>
The correct answer option is 48.
<u>Step-by-step explanation:</u>
In the given experiment, three events take place which include rolling a die, flipping a coin and spinning a spinner.
The possible outcomes of each of these events are as follows:
Rolling a die - 6
Flipping a coin - 2
Spinning a spinner - 4
Therefore, by multiplying their possible outcomes, we can find the number of elements in the sample space of this environment.
Number of elements = 6 × 2 × 4 = 48
