Recall the formula for growth of a sum of money :

A = P (1 + r)^t

where

A = Value after t time periods
P = Principle (Starting value)
r = rate per time period t
t = number of time periods

For this problem,

P = 12000
r = .15
t = 3

First, we must solve for A. Then we will take A-P to determine the interest paid.

A = P ( 1 + r)^t
A = 12000 (1 + .15)^3
A = 12000 (1.15)^3
A = $18,250.50

Thus, the amount after 3 years is $18,250.50. Since the initial amount borrowed was $12,000, Jack has accrued 

A - P = 18250.50 - 12000 = $6250.50

in interest.

Answer:

About 4.123

Step-by-step explanation:

The horizontal distance between the two points is 5-1 = 4 units. the vertical distance is 3-2=1 unit. Using the Pythagorean theorem, we can find that the length is:

\sqrt{4^2+1^2}=\sqrt{17}\approx 4.123

1.A bag has 4 green blocks, 3 red blocks, 2 blue blocks, and 1 yellow block. Find the probability of randomly selecting a block
maks197457 [2]

Answer: 1) 7/10  2) 15  3) 240  4) 1/4  5) 4/9  6) 1/20  7) No, not independent

Step-by-step explanation:

1. 4 green+3red+2blue+1yellow = 10 total

if 3/10 are red, then 7/10 are not red. So the second option, 7/10

2. 3 cartons in every 40

40*5 = 200

so do 3*5 = 15

so 15 or the third option

3. 40 out of 110

110*6 = 660

so do 40*6 = 240

so 240 or the fourth option

4.

Flipping heads: 1/2

rolling even: well, there is 2, 4, and 6, or 3 even numbers so 3/6 or 1/2

do 1/2*1/2 = 1/4

so 1/4 or the third option

5. Numbers more than 2: 3, 4, 5, 6 (4 numbers)

4/6 or 2/3 chance the first time, 2/3 chance the second time

do 2/3*2/3 = 4/9

so 4/9 or the second option

6. 5 dishes and 4 desserts

1/5 chance of picking the dish

1/4 chance of picking the dessert

do 1/5*1/4 = 1/20

so 1/20 or the fourth option

7. Since you don’t replace the marble after picking it, it affects the outcome of the second draw. Therefore the events are dependent, or not independent. So the second option.

Answer:

120 degrees.

Step-by-step explanation:

All the angles in a triangle add up to 180. You have two of the angles given:

50 degrees and 70 degrees

To find the third angle of the triangle (BAC), use the expression:

180 - (50 + 70)

180 - 120

60

So, the third angle in the triangle is 60 degrees. Looking at angle DAB, you can see that it forms a straight line with angle BAC. A straight line is 180 degrees. Since we know BAC is 60, and BAC + DAB = 180, by doing 180 - 60, you can see that angle DAB is 120 degrees.
