The man travelled in different ways: by rail, by taxi, by ___ and by foot. I placed a blank there because there seems to be a missing word in the given problem above. For sample purposes, let's just assume that is travel by bus.
Since all of these travels are equal to 1 whole journey, you can express each travel as a fraction. When you add them up, the answer would be 1. So,
3/8 + 1/4 + 1/8 + x = 1
The variable x here denotes the fraction of his travel by foot. We are only given the exact distance travelled on foot which is 2 km. We have to find the fraction of the travel by foot to determine the length of the total distance travelled. Solving for x,
x = 1 - 3/8 - 1/4 - 1/8
x = 1/4
That means that the travel by foot comprises 1/4 of the whole journey. Thus,
Let total distance be D.
1.4*D = 2 km
D = 8 km
Therefore, the man travelled a total of 8 kilometers.
Answer:
x = -5
x = -12
Step-by-step explanation:
- 7x - 60 = x^2 + 10x
add 7x to both sides
x^2 + 17x = -60
add 60 to both sides
x^2 + 17x + 60 = 0
factorise quadratic
(x + 12) (x + 5) = 0
<em>x = -12</em>
<em>x = -12x = -5</em>
Answer:
weres the question
Step-by-step explanation:
Answer: Choice B. Opposite/hypotenuse
The "opposite" refers to the leg that is furthest from the reference angle. The hypotenuse is always the longest side. The longest side is directly across from the 90 degree angle.
The probability that both of them have landed 5 is 1/7.
Two fair dice have been tossed,
The total of their top faces is found to be divisible by 5,
Probability is a branch of mathematics that deals with calculating the likelihood of a given event's occurrence, which is expressed as a number between 1 and 0.
The probability that both of them have landed 5 is
E={(x,y)|x+y=5 or x+y=10, 1≤x,y≤6},
F={(5,5)}.
P(F|E)= 1/7.
Hence, The probability that both of them have landed 5 is 1/7.
