aleksandr82 [10.1K]

Answer:

He will receive $515 for the 17 coins

Step-by-step explanation:

In this question, we are asked to calculate how much will be received for 17 coins , with each coin having a specific value in the US currency.

Obviously, there are four coins, so let’s proceed to get the amount he gets per type of coins.

For the m coin, she has 3 pieces. One m coin has a value of $10, then the amount of coins she makes on the m coins will be 3 * 10 = $30

For the a coin, he has 7 pieces. One m coin has a value of $5, then the amount of coins she makes on the a coins will be 7 * 5 = $35

For the t coin, he has 5 pieces. One t coin has a value of $50, then the amount of coins she makes on the t coins will be 5 * 50= $250

For the h coin, she has 2 pieces. One h coin has a value of $100, then the amount of coins she makes on the h coins will be 2* 100 = $200

The total amount made on the 17 coins would thus be mathematically equal to;

Amount made on m coins + Amount made on a coins + Amount made on t coins + Amount made on h coins

The total amount = $30 + $35 + $250 + $200 = $515

Answer:

x=3

Step-by-step explanation:

Because DE // AC

so DB/BE = DA/EC

x+5/4=2x/3

4(2x)=3(x+5)

8x=3x+15

5x=15

x=3

Jesse deposits her $500 into bank. Interest is 9.5%. She withdraws 737.50. How long did she keep her money in the account?
mario62 [17]
We'll need to assume that this is a case of compound interest which is paid once per year.

Then    A = P (1 + r)^t becomes

$737.50 = $500 (1+0.095)^t

Then ($737.50/$500) = 1.095^t

Take the log of both sides.  0.1688 = log 1.095^t, or 
                                             0.1688 = t log 1.095 = t(0.0394)

Solving for t,    t = 0.1688/0.0394 = 4.28 years 

This comes out to 4 years and 28/100 of one year, 
or                           4 years and 3.36 months, or
                               4 years, 3 months and 11 days.
