How long will the sum of Rs 5,000 take to reach the amount RS 8750 at the rate of 15% per annum

Nonamiya [84]

Answer:

It will take 5 yrs the sum of 5000 will take to reach Rs 8750 at the rate 15%

Step-by-step explanation:

T= ?

Amount = Rs 8750

R = 15%

P = Rs 5000

I = A-P

= 8750 - 5000

= Rs 3750

I = PTR/100

3750 = (5000*15*T)/100

or, 375000 = 75000*T

or, T = 375000/75000

so T = 5 yrs

In 1927, Charles Lindburgh had his first solo flight across the Antlantic Ocean. He flew 3,610 miles in 33.5 hours. If he flew a

PolarNik [594]

Answer:

107.76

Step-by-step explanation:

We are told in the above question that:

He flew 3,610 miles in 33.5 hours. If he flew about the same number of miles each hour, how many miles did he fly each hour?

We solve the above question by:

33.5 hours = 3610 miles

1 hour = x miles

Cross Multiply

33.5 hours × x miles = 3610 miles × 1 hour

x miles = 3610 miles × 1 hour/33.5 hours

x miles = 107.76119403 miles

Approximately = 107.76 miles per hour

Therefore, he flew 107.76 miles each hour

The area of the circle above is 314 units2. What is the circumference of the circle? use 3.14

aleksandrvk [35]

Answer:

$r =\sqrt{\frac{314 units^2}{3.14}} = 10 units$

And the circumference is given by this formula:

$C = 2\pi r$

And replacing the value fo r we got:

$C = 2\pi *10 units = 62.8 units$

And then the final answer would be 62.8 units for the circumference.

Step-by-step explanation:

For this case we know that the area for a circle is given by:

$A = \pi r^2$

And we know that $A = 314 units^2$

We can find the radius from the previous formula like this:

$r^2 = \frac{A}{\pi}$

$r^2 = \frac{314 units^2}{\pi}$

$r =\sqrt{\frac{314 units^2}{3.14}} = 10 units$

And the circumference is given by this formula:

$C = 2\pi r$

And replacing the value fo r we got:

$C = 2\pi *10 units = 62.8 units$

And then the final answer would be 62.8 units for the circumference.
