To find the percentage, divide 1.14 by 1.9 and multiply by 100:
(1.14 ÷ 1.9) x 100 = 60%
The number of pass candidates are 2 + 6 + 18 + 40 = 66 out of total 100.
Hence, Pass percentage = 66%
To find the average, we need to add the numbers and divide by the total count of numbers.
First, let's add the numbers:
0 + 0 + 4 + 10 + 5 + 5 = 24
There are 6 numbers in the list. To find the average, divide the sum by 6:
24 ÷ 6 = 4
So, the average is 4.
Hour hand moves 225° (7.5 hours).
Minute hand moves 180° (30 minutes).
Angle between them: 45° (difference) + 30° (hour hand's extra move) = 75°.
OR
= 8h x 30 - 30 x 11/2
= 240 - 165
= 75°
Total weight of (36 + 44) Students,
= (36 × 40 + 44 × 35) kg
= 2980 kg
Therefore average weight of the whole class,
= 298080 kg.
Therefore average weight = 37.25 kg.
To find the answer, we calculate the total work:
42 women x 18 days = 756 woman-days
Since the work remains the same, we divide the total work by 21 days:
756 woman-days ÷ 21 days = 36 women
So, 36 women can do the same work in 21 days.
To find the answer, divide 4.036 by 0.04:
4.036 ÷ 0.04 = 100.9
In this scenario, we can use the tangent function, which is the ratio of the opposite side (height of the tower, h) to the adjacent side (the horizontal distance, 70m):
