Answer: Not possible
Step-by-step explanation: A whole number is an integer or a number without fractions. Both 15% and 40% are less than 1 since they are less than 100%; therefore, it is impossible to express them as whole numbers. They can only be expressed as the mixed numbers of 0.15 and 0.4, or 15/100 and 40/100.
Answer: Height at which the wire is attached to the pole is 12 feet.
Explanation:
Since we have given that
Length of the wire = 20 feet
Let the height at which wire is attached to the pole be h
and distance along the ground from the bottom of the pole to the end of the wire be x+4
Now, it forms a right angle triangle so, we can apply "Pythagorus theorem".

But height cant be negative so, height will be 12 feet.
Hence, height at which the wire is attached to the pole is 12 feet.
Answer:
11 2/3 pounds.
Step-by-step explanation:
Let x pounds be the amount in pounds of Brazilian coffee.
x + 27 is the amount of coffee in lbs after the mixing.
So ,working in values of dollars, we have:
6x + 4*27 = 4.5(x + 27)
6x + 104 = 4.5x + 121.5
1.5x = 121.5 - 104 = 17.5
x = 17.5/1.5 = 11 2/3 pounds answer
