The present age of father is 86 years old and present age of son is 48 years old

<em><u>Solution:</u></em>

Given that, a father is now 38 years older than his son

Ten years ago he was twice as old as his son

Let "x" be the age of son now

Therefore, from given,

Father age now = 38 + age of son now

Father age now = 38 + x

<em><u>Ten years ago he was twice as old as his son</u></em>

Age of son ten years ago = age of son now - 10

Age of son ten years ago = x - 10

Age of father ten years ago = 38 + x - 10

Then we get,

Age of father ten years ago = twice the age of son ten years ago

38 + x - 10 = 2(x - 10)

28 + x = 2x - 20

2x - x = 28 + 20

x = 48

Thus son age now is 48 years old

Father age now = x + 38 = 48 + 38 = 86

Thus present age of father is 86 years old and present age of son is 48 years old

In the measurement of 67.93 cm, which digit is estimated? click on the estimated digit
scoundrel [369]
When it comes to measurement, the most accurate estimate would be the whole number. A ruler has calibrated marks. It would be easy to locate 25. But when it is located between 25 to 26, you would have to estimate the decimal points. Generally, calibration marks are up to the tenths digit. For further digits, that would only an estimation. So, the estimated digit in this problem is 3 in the hundredths place.

You are planning to invest $500 at 12% compounded annually. How much money would you have after 10 , 20 and 30 years?
Serjik [45]

A=P(1+r)^t

where A=final amount

P=principal

r=rate in decimal form

t=time in years


we are given that P=500, r=12%=0.12

we want to find A when t=10, 20, and 30


so

A=500(1+0.12)^t

A=500(1.12)^t

when t=10, A=500(1.12)^{10}=$1552.92

when t=20, A=500(1.12)^{20}=$4823.15

when t=30, A=500(1.12)^{30}=$14980.96
