What is the greatest common factor of 14 56 63?

Answers

The greatest common factor of 14, 56, and 63 is,

⇒ 7

We have to give that,

Numbers are,

14, 56 and 63

Since, The highest number that divides exactly into two more numbers, is called Greatest common factor.

Now, Factors of the numbers are,

14 = 2 x 7

56 = 2 x 2 x 4 x 7

63 = 3 x 3 x 7

Hence, the greatest common factor of 14, 56, and 63 is,

⇒ 7

Find the balance in the account: $1,600 principal earning 7%, compounded semi-annually, after 33 years

Answers

A principal invested for n number of years increases as the equation projects F = P * (1+ i) ^n where F is the future worth, p is the present worth or principal and i is the interest rate. substituting, F = $1600 * (1+ 0.07/2) ^33*2 equal to amount of future worth or balance of  $15494.70

Answer:

$15,494.70

Step-by-step explanation:

Compounding twice year, 3.5% each, 66 times  

result=$1,600*1.035^66 = $15,494.70  


The answer to 25. please

Answers

14, finding the rate of change is simple,
142-128 = 14
156-142 = 14
170-156 = 14
184-170 = 14

14+14+14+14 = 56

There are 4 integers so divide by 4

56/4 = 14

so the answer is 14
