To solve this, first make an equation:

750(x)^{12}=1500

After you solve this, you get x = 1.0399, but we have to subtract 1 so we get 0.0399 which is 3.99%

2. Jessica's financial advisor believes that she should spend no more than 28% of her gross monthly income for housing. She has
scoray [572]

Jessica's annual salary is $68571.43.

Data;

  • percentage saved for housing = 28%
  • amount saved annually = $1600

<h3>Percentage</h3>

This is the ratio of a number to the entire value and multiplied by 100

The percentage set aside for housing is given as 28% which is $1600.

Let find 28% of x which is equal to 1600

\frac{28}{100} = \frac{1600}{x}

cross multiply both sides and solve for x

\frac{28}{100}  = \frac{1600}{x}\\ 28*x  = 100*1600\\28x = 160000\\

Divide both sides by the coefficient of x

\frac{28x}{28} = \frac{160000}{28}\\ x = 5714.28

Her monthly income is $5714.28.

Let's multiply this by 12 (months in a year) to determine her gross monthly income.

5714.28*12 = 68571.43

From the above calculations, Jessica's annual salary is $68571.43.

What is BC will give brainliest
Alexxandr [17]

Because two angles are equal, sides AB and AC will have equal lengths, and so, we can set each expression equal to each-other.

4x + 4 = 6x - 14

Subtract 4x from both sides.

4 = 2x - 14

Add 14 to both sides.

18 = 2x

Divide both sides by 2.

x = 9.

Because we have a constant value of x, we can solve for BC.

BC = 2x + 7

2(9) + 7

18 + 7

25

<h3>The value of BC is 25.</h3>

Is 5/6 closer to 0,1/2 or 1
swat32
It is closer to 1. 5/6 is 16 less than 1 and 5/6 is 1/3 more than 1/2, so it would be closer to 1.

Consider the right triangle in the figure below and determine the value of<br> a, b, c, and d.
Goryan [66]

The unknown values are as follows:

a = 48.7°

b = 51.43

c = 12.16

d = 122.39

<h3 />

<h3>Properties of a right angle triangle:</h3>One angle is equals to 90 degrees
  • The sides and angle can be calculated using trigonometric ratios

Therefore,

sin 72.3° = opposite / hypotenuse

sin72.3° = 49 / b

b = 49 / sin 72.3

b = 49 / 0.95266148125

b = 51.4348495916

b = 51. 43

a = (180 - 90 - 23.6) - (180 - 72.3 - 90)

a = 66.4 - 17.7

a = 48.7°

tan 23.6 = opposite /adjacent

tan 23.6 = 49 / c

c = 49 / tan 23.6

c = 112.158945248

c = 12.16

sin 23.6 = opposite /hypotenuse

sin 23.6 = 49 / d

d = 49 / sin 23.6

d = 49 / 0.40034903255

d = 122.39
