Micah deposited $4000 between two savings account. One account earns 4% simple interest each year. The other account earns 2% simple interest. Last year Micah earned $140 interest on the accounts. What amount was originally deposited into the account that pays 4% interest?

Answers

Answer:

The amount that is deposited at 4 % simple interest is $ 3000.

Step-by-step explanation:

Given, the total amount deposited = $ 4000,

Let x be the amount that is deposited at the rate of 4 % simple interest,

⇒ The amount deposited at the rate of 2% simple interest = ( 4000 - x ) dollars,

We know that,

The simple interest on an amount is,

$I=(P* r* t)/(100)$

Where, P is the principal amount, r is rate of interest and t is time,

Thus, the total interest he earned in a year

$I=(x* 4* 1)/(100)+((4000-x)* 2* 1)/(100)$

$=(4x)/(100)+(2(4000-x))/(100)$

$=(4x+2(4000-x))/(100)$

According to the question,

I = $ 140,

$\implies (4x+2(4000-x))/(100)=140$

$(2x+8000)/(100)=140$

$2x+8000=14000$

$2x=6000$

$x=3000$

Hence, the amount that is deposited at 4 % simple interest is $ 3000.

$3000 * 0.04 = $120
$100 * 0.02 = $20

total 2 accounts = $120 + $20 = $140

answer: $3000 was the originally deposited into the account that pays 4% interest.

i think the answer is D because its multiplying by 2 each time

D) 2, 4, 8, 16, 32

Explanation:

In order for it to be a geometric sequence, it has to be multiplied by the same number every time. The only equation that demonstrates this is the last one since it is being multiplied by 2 every time.

The geometric sequence equation is
A(n) = a* r^{n-1}
a( n ) = term in the sequence
a = first term
r = common ratio (what it's multiplied by every time)

marvin has a chain that is 3 5/12 feet long . he uses 2 1/3 feet of the chain , how much chain is left

Answers

In order to calculate left chain, you need to subtract that as follows:
Left chain = 3 5/12 - 2 1/3
L.C. = 41/12 - 7/3
L.C.= 41-28 / 12
L.C. = 13/12

In short, Your Answer would be 13/12 feet or 1 1/12 feet

Hope this helps!

the answer is 1 1/12, to do that. make 1/3 into 4/12 and subtract 5/12 - 2 4/12= 1 1/12, Hope this helps :)
