How much money should be deposited today in an account that earns 6% compounded semiannually so that it will accumulate to $14,0
Free_Kalibri [48]

Answer:

The amount of money to be deposited today is $11,725

Step-by-step explanation:

In this question , we are concerned with calculating the amount of money that should be deposited presently to have $14,000 in three years.

To get this, we have to use the compound interest formula

A = P( 1+ r/n)^nt

where A is the amount to be earned after the end of the compounding period which is $14,000 according to this question

P is the initial amount to be deposited which is what we are looking for

r is the rate of compounding which is 6% or simply 6/100 = 0.06

n is the number of times interest is compounded yearly which is semiannually according to the question and this means 2

t is the number of years which is 3 according to the question

Now, plugging all these values, we have;

14,000 = P( 1 + 0.06/2)^(3 * 2)

14,000 = P(1+0.03)^6

14,000 = P(1.03)^6

14,000 = 1.194P

P = 14,000/1.194

P = 11,724.77 which is approximately $11,725

Bolts are packed into bags at a factory. Each bag should have 25 bolts in it but a bad with 22 or 28 is acceptable. Formulate an
Viefleur [7K]

Answer:

Absolute value equation is; |x - 25| ≤ 3

Minimum number of bolts is 22 while Maximum number of bolts is 28

Step-by-step explanation:

We are told that;

Each bag should have 25 bolts in it but 22 or 28 is acceptable.

Since 22 or 28 is acceptable, it means the allowable error is ±3.

Thus, if x is the number of bolts in the bag, the absolute value equation would be;

|x - 25| ≤ 3

Minimum number of bolts is 22 while maximum is 28

6(1-5m) =
Delvig [45]

Answer:

6(1-5m) = 6 − 30 m

3(4+3r) = 12 + 9 r

3(6r+8) = 18 r + 24

4(811+ 1+2) = 3256

-(-2-n) 7) = 14 + 7 n

-6(7k+11) = − 42 k − 66

-3(71+1) = − 216

-6(1 +116) = − 702

-10(a - 5) = − 10 a + 50

-3(1 + 2v) = − 3 − 6 v

-4(3r+2) = − 12 r − 8

(3 - 76)-2 = − 75

(-2018x+20) = − 2018 x + 20

(7 + 190)-15 = 182

(x + 1)14 =​ 14 x + 14
