So you have to simplify
(9 x 10 x 18) 2 + (5 x 10 x 18) (-7) + (5 x 9 x 18)
(-11) + (5 x 9 x 10)
5 x 9 x 10 x 18
1620 x 2 + 900 (-7) + 810(-11) + 450 x 5
x 5 x 9 x 10 x 18
The answer would be -6/5
Answer:
2/π ≈ 0.637 m/s
Step-by-step explanation:
The rate of change of area with respect to time is ...
A = πr²
dA/dt = 2πr·dr/dt
Filling in given values in the above equations, we can find r and dr/dt.
25π = πr² ⇒ r = 5
20 = 2π·5·dr/dt
dr/dt = 20/(10π) = 2/π . . . . meters per second
The radius is increasing at the rate of 2/π ≈ 0.637 meters per second.
Given: £90 is divided among Aahil, James and Merav in the ratio 1:3:5.
To find: How much Merav gets.
Answer:
Let's assume the shares of each to be 'x'.
This implies that 1x + 3x + 5x = 90.
9x = 90
x = 90/9
x = 10
Substituting this value of x in the ratio,
- 1 × 10 = 10 [<em>Aahil's share</em>]
- 3 × 10 = 30 [<em>James' share</em>]
- 5 × 10 = 50 [<em>Merav's share</em>]
Therefore, Merav gets £50.
