Answer:
L = 15.53 ft
Step-by-step explanation:
using diagram which is attached below
now, using Pythagoras theorem
L² = b² + (5 + x)²...............(1)
using similarity of triangle
from equation (1)
for maxima or minima
x = -5 and x = ∛190 = 5.74
on second derivative 5.74 is the value which comes out to be minimal value which is the distance between the fence and ladder
now,
L² = 241.38
L = 15.53 ft
Answer: true
Step-by-step explanation: first you divide its circumference by pi, which you then get 17.990. Round it to 18. Then use the diameter (18) and divide it by 2. You get 9.
-3x-3 = 4x-3
-3 = 7x-3
0 = 7x
x = 0
Answer:
$108
Step-by-step explanation:
The computation of the total profit is shown below:
Given that
1 box = $12
18 boxes = 12×18 = $216
So
Total = 18×65 = 1170 pens
Now Cost price, Cp = $216
Also,
3 = $1
So,
= 378 ÷ 3
= $126
Now
= 1170-378
= 792 pens remaining
4 = $1
So,
792
= 792 ÷ 4
= $198
Now
Total selling price, sp = 126+198 = $324
So finally
Profit = Sp - Cp
= $324 - $216
= $108
20:15 which reduces to 4:3 or 4/3 or 4 to 3 , hope that helped have a good day
