Answer:

a. $4,415.25

b. $4,376.70

c. 2.27986 years

Step-by-step explanation:

a.

A = 4,000 (1 + 0.05/2)^(2 x 2)

   = $4,415.25

b.

A = 4,000 x e^(0.045 x 2)

   = $4,376.70

c. $100 more than option 2 = 4,376.70 + 100

                                              = $4,476.70

t (in years) = ln(4,476.70/4,000) /  ln(1 + 0.05/2)

                 = 2.27986 years

Assume that your present job pays a monthly gross salary of $1,560. You are offered a new position that pays $8.60 per hour with
motikmotik

Answer:

There are 4 weeks in a month and 40 working hours in a week

Since the $8.60 per hour, the gross monthly salary for your new position = 8.60*40*4 = $1,376

Your gross monthly salary at present job = $1,560

So the additional amount that you need to earn at your new position = 1,560-1,376 = $184

The hourly wage for addtional hours more than 40 hours at the new position = 1 1/2 * 8.60 = 1.5*8.60 = $12.90

So, number of hours that you need to work extra = 184/12.90 = 14.26 hours per month

So, number of hours that you need to work extra per week = 14.26/4 =  3.566 hours or 3.57 hours (Rounded to 2 decimals)

Now multiply 496.5 by 3 =  1, 489.5 = 3/4


I hope this helps! :_

The least common multiple of two numbers is 3780, and the greatest common divisor is 18. given that one of the numbers is 180, w
garri49 [273]
<span>To solve these GCF and LCM problems, factor the numbers you're working with into primes: 
3780 = 2*2*3*3*3*5*7
180 = 2*2*3*3*5 
</span><span>We know that the LCM of the two numbers, call them A and B, = 3780 and that A = 180. The greatest common factor of 180 and B = 18 so B has factors 2*3*3 in common with 180 but no other factors in common with 180. So, B has no more 2's and no 5's
</span><span>Now, LCM(180,B) = 3780. So, A or B must have each of the factors of 3780. B needs another factor of 3 and a factor of 7 since LCM(A,B) needs for either A or B to have a factor of 2*2, which A has, and a factor of 3*3*3, which B will have with another factor of 3, and a factor of 7, which B will have. 
So, B = 2*3*3*3*7 = 378.</span>
