Question number: 67
Write in Short
There are approximately 1000 divisor lines on a road in between 12 kilometers distance. Solve for number of divisors in 6500 meters distance.
(b) Jot down answer in standard form.
Here, 1000 divisor lines on a road in between 12 kilometers distance.
So, 12000 meters = 1000 divisors
6500 meters =? Divisors
(b) Standard form of
So, for making standard form we need to shift decimal point from right to left two times.
So, it will be: .
Question number: 68
Describe in Detail
A ramp from a parking to a shopping mall slopes upward at an angle of to the horizontal. The length of the slope is 15 meters. Find difference in height h between the parking and the shopping mall. Give answer in meters.
Here, as given angle A is , AC = 15 m and we need to find length of BC which is difference of the height of mall and parking.
So, by using formula:
