Answer:
4 hours
Step-by-step explanation:
The speed of the first car is
While the speed of the second car is
The time it takes for each car to cover a distance d is
where
d = 960 km is the total distance covered
For car 1, the time taken is:
For car 2, the time taken is:
Therefore, the difference in time is:
Answer:
Step-by-step explanation:
You can use the work they gave you and continue from there:
First, simplify the numerator:
Finally, simplify the denominator:
Answer:
31
Step-by-step explanation:
50 x 0.62 = 31
Y = x - 9 meets the y-axis at (0,-9)
y = -2x - 3 meets the y-axis at (0,-3)
This is because for every linear equation, there is a formula corresponding to it as y=mx + c, where (0,c) is where it meets the y-axis. As we assign the value of 0 to x, only c will be left to equal y, being the intercept.
Answer:
f(t) = 62 ⋅ 0.9953t
Step-by-step explanation:
The function decreases at a rate of 0.47%
That will mean, the initial value decreases by 0.47?
100% - 0.47% = 99.53%
The next value will be 99.53% of the initial value.
∴ 99.53% × 62 = 0.9953 × 62.
After a time t, the value will be:
0.9953t × 62
∴ Answer = 62 × 0.9953
