For this case we have to rewrite the given expression algebraically:
the cube of a, is represented as: 
the square of b, is represented as:
Thus, the product of both expressions is:
And twice the product is represented as:
Answer:
Answer:
8 hours
$480
Step-by-step explanation:
Let us assume the hours be x
There should be two equations
For Plumber A = 60x
For Plumber B = 40 + 55x
Now in order to considered the cost to be the same we equate these two equations
60x = 40 + 55x
5x = 40
x = 8 hours
Now the total cost for plumber A is
= 480
And, the total cost for plumber B is
= 40 + 55(8)
= 480
hence, the total cost is $480
Answer:
120 people [see below]
Step-by-step explanation:
48 out of 120 people like baseball.
That is about 48/120 = 0.4 [40%]
Now, 3/5th of THOSE, play baseball, so
0.4 * 3/5 = 0.4 * 0.6 = 0.24 [24%].
Thus, we have seen that around 24% of total people taken would play baseball.
Now, we take 500 people, so 24% of them would be expected to play baseball.
That is 0.24 * 500 = 120 people
To get the
Mean, you have to add all the ages of the men together:
Next you divide
by the amount of people:
Final Answer: 26
