Answer:
52/3
Step-by-step explanation:
Use basic Thales therom,
Cross multiply,
3*(5x-8)=4*(3x+7)
3*5x - 3*8 = 4*3x + 4*7
15x - 24 = 12x +28
Add 24 to both sides
15x = 12x + 28 + 24
15x = 12x + 52
Subtract 12x from both sides
15x-12x =52
3x = 52
Divide both sides by 3
x = 52/3
Answer:
1/2
Step-by-step explanation:
First square area = 4cm^2, thus the side length is 2cm
Second square area = 16cm^2, thus the side length is 4cm
This gives a ratio of 2/4, simplifying yields 1/2
Answer:
6th week.
Step-by-step explanation:
Each week he is selling 1/2 of the week before so
In the 3rd week he sells 400
- in the 4th week it will be 200
- in 5th week 100
- in 6th seek 50.
First draw p yellow = 4/7
2nd draw p red = 3/7
3rd draw p red = 3/7
To find the probability of this event (1yellow 2 red - with replacement) we multiply the probabilities.
4/7 x 3/7 x3/7 = 36/343 which cannot be reduced further
