A principal of $2900 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 14 years?

Answers

Answer:

$6774.4

Step-by-step explanation:

Given data

P=$2900

r= 6.25%

t= 14 years

A=???

The compound interest formula is given as

A=P(1+r)^t

substiute

A= 2900(1+0.0625)^14

A= 2900(1.0625)^14

A= 2900*2.336

A= $6774.4

Hence the final amount is $6774.4

if you form a triangle from three given angle measures, do you always get a unique triangle, or more than one triangle?

Answers

It depends on the measurements. If you have equal measurements, it would just be an equilateral triangle. If you got measurements that had two of the same degrees, that would be isosceles. Measurements that are all different to one another would be a scalene triangle.

A bag contains 5 red marbles, 8 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be red?

Answers

Without replacement, the probability that all three marbles drawn will be red is 0.01.

What is the probability?

Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.

Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)

5/17 x 4/16 x 3/15 = 0.01

The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%

How to calculate probability?

We are given;

Number of red marbles = 5

Number of blue marbles = 8

Number of Green marbles = 4

Total number of marbles = 5 + 8 + 4

Total number of marbles = 17

Probability of first being red = 5/17

Probability of second being red = 4/16

Probability of third being red = 3/15

Thus;

P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)

P(all three marbles drawn are red) = 0.0147

Approximating to nearest tenth of a percent = 0.015 = 1.5%

Step-by-step explanation:

What is the problem, can you write it better pls?

Answer:

x = - 3 and x = 1

Step-by-step explanation:

4x - 2 - 2x = x - 5, that is

2x - 2 = x - 5 ( subtract x from both sides )

x - 2 = - 5 ( add 2 to both sides )

x = - 3

----------------------------------------

- (x + 3) = 2x - 6 ← distribute left side

- x - 3 = 2x - 6 ( subtract 2x from both sides )

- 3x - 3 = - 6 ( add 3 to both sides )

- 3x = - 3 ( divide both sides by - 3 )

x = 1

please help with an explanation.

Answers

Answer & Step-by-step explanation:

Let's have

C = Creepers

B = Balloons

1) 6C + 20B = 11.9  

2) 2C + 15B = 6.05

Eliminate

16C + 20B = 11.9 x3  

-2C + 15B = 6.05 x4

18C + 60B = 35.7  

-8C + 60B = 24.2

10C/10 = 11.5/10
