The relationship between x and y is proportional. When x is 3, y is 51. What is the value of x when y is 204?

Answer:

Triangle ABC is not a right triangle because d) it doesn't have a pair of perpendicular sides

Step-by-step explanation:

Perpendicular sides mean that the slopes are "opposite reciprocals" of each other.

Example: slope is 1/2 and the perpendicular line's slope is -2

How? 1/2 changes to 2 (you flip it, reciprocal), and then from 2 to -2 (apply opposite sign)

So when you calculate the slopes of AB, AC, and BC, none of their slopes are opposite reciprocals of each other. You can calculate the slopes of each and compare them if you want to check.

I really hope this helps, do you think you can tell me if you got the answer correct? I'd feel really bad if you got it wrong because of me. All I know is that it's not a right triangle.

The possible heights for the University of Central Florida’s cheerleaders is:

5 feet, 11 inches

5 feet, 3 inches

4 feet, 9 inches

5 feet, 8 inches

Let h represents the height of a team member.

Since the height of a team member is given by the inequality 260 ≤ 4h + 28 < 324, hence:

260 ≤ 4h + 28 or 4h + 28 < 324

4h + 28 ≥ 260 or 4h + 28 < 324

4h ≥ 232 or 4h < 296

h ≥ 58 inches or h < 74 inches

Therefore the height of the team member is at least 58 inches (4 feet 10 inches) and less than 74 inches (6 feet 2 inches)

The possible heights for the University of Central Florida’s cheerleaders is:

5 feet, 11 inches

5 feet, 3 inches

Answer:

You would have to rent 28 movies.

Step-by-step explanation:

You would set up the problem as a system of equations. This means that you have to have two equations.

Dish: [tex]y=3.50x+40[/tex]

Direct TV: [tex]y=2.25x+75[/tex]

In order to find the answer to these, you can either graph them or set them equal to each other. If you graph them, the answer is where the two lines intersect. For this, we will set them equal to each other:

[tex]3.50x+40=2.25x+75[/tex]

To start, since there is a number with the same variable on both sides, we must subtract the lower one from both sides of the equation. In this case, we will subtract [tex]2.25x[/tex] from both sides, giving us:

[tex]1.25x+40=75[/tex]

Now, we solve like a normal two-step equation.

Subtract 40 from both sides:

[tex]1.25x=35[/tex]

After that, we will divide both sides of the equation by 1.25:

[tex]\frac{1.25x}{1.25}=\frac{35}{1.25}[/tex]

This gives us:

[tex]x=28[/tex]

Which means you would have to rent 28 movies exactly in order for their prices to match.

Answer:

26%

Step-by-step explanation:

$22,500-$16,650= $5,850

I started by multiplying buy 0.20 from $22,500 and then Jumped to 0.25% and when I realized i was close I multiplied $22,500 *0.26  and matched the decreasing price of $5,850.

$22,500*0.20 = $4,500 off

$22,500*0.25 = $5,625 off

$22,500*0.26 = $5,850 off

$10,000 is invested at annual compound interest. After 4 years, the investment has become $11,608.86. What annual rate of compound interest was used?

Answer: 3.8%

The annual rate of the compound interest is given as 3.8%.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Amount = principal[1 + r/n]ⁿᵃ

Principal = P rate= r Time =a  , n = compounding frequency

Here,
Amount = principal[1 + r/n]ⁿᵃ
11608.86 = 10000[1 + r/1]⁴
1.160886 = [1 + r]⁴
1 + r = 1.038
r = 1.038 - 1
r = 0.038
r% = 0.038 ×100%
r% = 3.8%

Thus, the annual rate of the compound interest is given as 3.8%.

Answer:

y - 1 = -3/2(x - 0)

Step-by-step explanation:

trust me

The equation of the line in point-slope form is y - 1 = -3/2(x - 0).

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that line that passes through the (0,1) and has a slope of -3/2. The equation of the line will be written as,

y - y₁ = m(x-x₁)

y - 1 = (-3 / 2) ( x - 0 )

Therefore, the equation of the line in point-slope form is y - 1 = -3/2(x - 0).
