Decimal 0.003 is 1/10 of

1 answer:

6 0

Just multiply the 0.003 by 10 and you'll get the result. The easiest way to multiply such numbers is to move the dot one position to the right (it would be 2 positions if multiplied by 100, 3 by 1000 etc.). You can do the same with dividing, just remember to move to the left then.

So 0.03 is your answer

On your tenth birthday, you received 500 which you invested at 9.5% interest, compounded annually. your investment is worth $250

igomit [66]

Compounded once a year: A=P(1+r)^t
2500=500(1+0.095)^t
1.095^t=5
because the unknown number is an exponent, use log to find the unknown:
log(1.095^t)=log5
tlog1.095=log5
t=log5/log1.095
use your calculator, t=17.734
so this person is about 28 years old.

Donald has a bunch of nickels and dimes in his piggy bank. There are 100 coins in the bank that make a total of $6.60 in change.

brilliants [131]

Answer:

78 nickels and 22 dimes

Step-by-step explanation:

Nickels = n, Dimes = d

Number of coins = 100

n + d = 100

Total sum in the piggy bank = $6.60

5n + 10d = 660

Consider the first equation in the second:

5(100 -d) + 10d = 660
500 - 5d + 10d = 660
5d = 110
d = 110/5
d = 22
n = 100 - 22
n = 78

Answer: nickels 78 and dimes 22
