If $1=Rs. 102.50 and £ 1=Rs, 140, how many dollars equals to £5?

$6.83= £5

Step-by-step explanation:

As £ 1=Rs 140

So, £5 = Rs 140 x 5

£5 = Rs 700 ...(i)

Now, Rs. 102.50 = $ 1

So, Rs. 1 = $ (1/102.5)

Therefore, Rs. 700 = $ (1/102.5)x 700 = $6.83

By using equation (i)

£5 = $6.83

Hence, there are $6.83= £5

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
