Answer: L = 50 while W = 17
Step-by-step explanation:
So, n=42
L = n + 8
L = 42 +8
L = 50
W = n/2 - 4
W = 42/2 - 4
W = 21 - 4
W = 17
The distance of Brandon’s bike in each interval of time can be represented in the attached Table 1.
Further explanation:
Given:
Brandon enters in to the bike race and he bikes in every .
Calculation:
It is given that in every Brandon bikes .
The distance is in the form of mixed fraction.
Therefore, the distance can be written in the form of decimal as follows:
Brandon bike's in every .
We know that is equivalent to .
So, can be converted into minutes as follows:
Therefore, in every Brandon bikes .
So, in next Brandon also bikes .
In every Brandon travels .
In every Brandon travels .
Method 2:
Speed of Brandon’s bike can be calculated as ,
…… (1)
Here, is the distance and is the time.
The distance is and time is .
Now, substitute and in the equation (1) to obtain the speed as follows:
Therefore, the rate of travelling of Brandon’s bike is .
The distance of Brandon’s bike in each interval of time can be represented in the attached Table 1.

The probability of randomly picking out a red marble is 1/5
To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.
Total marbles = 5 green + 3 blue + 2 red = 10 marbles
Red marbles = 2
So, we have
Probability = (Number of favorable outcomes) / (Total possible outcomes)
This gives
Probability = (Number of red marbles) / (Total marbles)
By subsituition
Probability = 2/10 = 1/5
Hence, the probability of randomly picking out a marble and it being red is 1/5

Answer:
1/5
Step-by-step explanation:
Since there are 2 red marbles and since there are a total of 10 marbles, the probability is 2/10. This simplifies to 1/5. So the probability of picking a red marble is 1/5.
Answer:
x = ± 2.45
Step-by-step explanation:
Given
8x² - 48 = 0 ( add 48 to both sides )
8x² = 48 ( divide both sides by 8 )
x² = 6 ( take the square root of both sides )
x = ± = ± 2.45 ( nearest hundredth )
