Answer:
1728/ 125
Step-by-step explanation:
The ratio of corresponding lengths of the figures = ratio of the square root of their areas.
So ratio of lengths = 12/5.
Now volume is 3 dimensional so the ratio is the cube of the lengths
= 12^3/5^3
= 1728/ 125.
Answer:
25
Step-by-step explanation:
Answer:
V = π × r² × h
Step-by-step explanation:
All you need to do is multiply the base times the height and since the base is a circle whose formula is π × r², we get π × r² × h.
8 Broken toys : 42 total toys = 1 Broken toy : 6 total toys
20 Broken toys : 105 total toys = 4 Broken toy = 21 total toys.
Answer: No: They are not proportional.
Answer:
9/25
Step-by-step explanation:
Our box contains 10 socks. (6, which are black and 4 which are red)
Probability of picking 1 black sock will be 6/10
Number of ways it can occur / Total number of outcomes.
In this question we pick two socks, one black firstly and another black, in the second turn. When we say AND, it means intersection
P (B₁ ∩ B₂) = 6/10 . 6/10
When the events are independent, the probability of the intersection will be the product of the probabilities,
P (B₁ ∩ B₂) = 36/100 = 9/25
