100% + 25% is 120% then 120 as a decimal 1.20 then you do 1.20 x 65 = 78
soo the selling price is $78
To arrange in descending order or greatest to least, we will first convert all the values in same unit.
Lets convert all the values in kg
1 lb = 0.45 kg
2 lb =
kg
1 g = 0.001 kg
891 g =
kg
1 T = 907.185 kg
0.02 T =
kg
Hence all values in kg becomes = 0.90 kg , 0.891 kg , 1 kg , 18.14 kg
So in descending order the values become
0.02T, 1 kg, 2 lb, 891 g
8 and 10 are possible lengths of the third side.
Answer:
Step-by-step explanation:
(a) 
Suppose 
by differentiation;

Suppose n = 3
Then, the integral




recall that 
Then;

(b) 
suppose; 



If n = u, then the integration is:




Since; 
Then;

(c) 
Suppose 
Then, by differentiation of both sides


Suppose n = 4 in integration, then:

By substitution;
