Answer:
Length = 5 feet
Breadth = (5/3) feet
Height(depth) = 2 feet
Volume of the entire tank = Length x Breadth x Height
= 
----------(1)
Water is filled upto a height of (1/3) feet
Volume of water in the tank = Length x Breadth x Height
= 
-------------(2)
Volume of space needed to be filled = (1) - (2)
= 
OR
Height of tank needed to be filled = 2 - (1/3) = (5/3) feet
Volume of space = Length x Breadth x Height of empty tank
= 
Answer: 60 students
Step-by-step explanation:
So, in the first situation 430 students were surveyed and 258 said that their favourite pet was a dog. The second situation is 100 students and x said that their favourite pet was a dog. We are solving x.
430=258
100= x
Cross multiply
So that is
430 x X= 100x258
430x=25800
Divide both sides by 430
Answer: 60 students
Answer:
I believe... x=12
Step-by-step explanation:
5x = 4x + 12
5x - 4x = x
therefore, x = 12
hope this helps :)
You take the total number of picture and multiply it by .12, which will get you the total number of black and white photos only.
600(.12)= 72
Answer:
14.656%
Step-by-step explanation:
Data provided in the question:
Rate of return, r = 4% = 0.04
Risk aversion of A = 1.85
Standard deviation, σ = 24%
Now,
we have the relation
A = (E - r) ÷ σ²
E = expected return on portfolio
r = Risk free rate
on substituting the respective values, we get
1.85 = (E - 0.04) ÷ (0.24)²
or
0.0576 × 1.85 = (E - 0.04)
or
0.10656 + 0.04 = E
or
E = 0.14656 or
E = 0.14656 × 100% = 14.656%
