Answer:
circle P has a circumference of 800mm which is equal to 80cm
circle Q is 200cm
circle R is 4m which is equal to 400cm
You will get the sum of the distances by placing the figures under one measurement that is meters
And so add the figures in cm(200+400+80) and get 680
Then convert this to meters and get 6.8m
Hence your answer is C

The solutions are x = -7 and x = 1. I used a graphing calculator for this.
Answer:
0.636
Step-by-step explanation:
Let Aw, Ab, Bw, Bb the following events:
Aw = the ball drawn from urn A is white
Ab = the ball drawn from urn A is black
Bw = the ball drawn from urn B is white
Bb = the ball drawn from urn B is black
the probability that the transferred ball was black given that the second ball drawn was black is P(Ab | Bb)
By the Bayes' Theorem
Working out the calculations
rounded to three decimals
Step-by-step explanation:
The dimensions of the cuboid are 5 cm, 7 cm and 9 cm.
The formula for the surface area of the cuboid is as follows :
We have,
b = 9 cm, l = 7 cm and h = 5 cm
So,
Jamie forgets to multiply 143 by 2 as the formula for surface area contains 2 as well.
