Answer:

1. The fraction is 11/9

Step-by-step explanation:

You didn't specify which ones you need help with so I'm answering the first one for you.

let x=1.2 —equation 1

10x=12.2 —equation 2

subtract equation 1 from 2

10x-x=12.2-1.2

9x=11

x=11/9

p borrowed Rs. 16000 from a person at 12 % per Annum simple interest and lent the whole amount to Q at the same rate of annually
hichkok12 [17]

Answer:

P earned $ 718.85.

Step-by-step explanation:

Given that P borrowed $ 16000 from a person at 12% per annum simple interest and lent the whole amount to Q at the same rate of annually compound interest, to determine how much did he gain after 3 years the following calculation must be performed:

16,000 x 0.12 x 3 = X

1,920 x 3 = X

5,760 = X

16,000 x (1 + 0.12 / 1) ^ 3 = X

16,000 x 1.12 ^ 3 = X

16,000 x 1.404928 = X

22,478.85 = X

22,478.85 - 16,000 = 6,478.85

6,478.85 - 5,760 = X

718.85 = X

Therefore, P earned $ 718.85.

Help??

The tree is 52.8 feet, since the hypotenuse is only part of the tree, you have to add 12, since then it would equal the total height of the tree.

a^2+b^2=c^2
12^2+ 39^2=c^2
144+1521= 1665
√1665
= 40.8

40.8 + 12
= 52.8 feet
