Answer:
It will take the apprentice 24 days working alone
Step-by-step explanation:
Let the number of days it takes the apprentice be x
It will take the landscaper x/3 ( since he is three times faster)
The rate for both will be 60/6 = 10 sq m per day
Rate for apprentice is 60/x
rate for the boss is 60/x/3 = 180/x
Adding the rates together;
60/x + 180/x = 10
240/x = 10
240 = 10x
x = 240/10
x = 24 days
The mean is the average of the numbers. to find the mean add up the numbers and divide by how many numbers there are
This is the answer if you mean 719-26
700-30= 670
<h3 /><h3>V. Cylinder = π . r² . h</h3>
12,704.44 = 3.14 × r² × 14
12,704.44 = 3.14 × 14 × r²
12,704.44 = 43.96 × r²
r² = 12,704.44/43.96
r² = 289
r = √289
r = 17

(x^2 - 13x - 48) ÷ (x + 3)
x - 16
_____________
x + 3 | x^2 - 13x - 48
| x^2 + 3x
|__________
| -16x - 48
| -16x - 48
Therefore, (x^2 - 13x - 48) ÷ (x + 3) = x - 16
