What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.
Answers
Answer:
That is a 30 60 90 triangle.
In such a triangle the "middle" size = short side * sq root (3)
height = 5 * sq root (3) = 8.6602540378
Area = (1/2) * 5 * 8.6602540378
Area = 2.5 * 8.6602540378
Area = 21.6506350946 square centimeters

Answer:
A=24√3
Put In Decimal Form:41.5692193817^3
Step-by-step explanation:
4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.
A=1/2(4)(4√3)
2(12√3)
24√3

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000
Answers
Answer:
18.6%
Step-by-step explanation:
What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000
Percentage increase is calculated as:
Final value - Initial value/ Initial value × 100
Final value = 510000
Initial value = 430000
Percentage Increase =
510000 - 430000/430000 × 100
= 80000 / 430000 × 100
= 0.1860465116 × 100
= 18.604651163 %
Approximately = 18.6 %

How can you write an equation of a line when you are given the slope and the y-intercept of the line? Explain
Answers
Answer:
The linear equation that represents each function is y=mx+b. While The m represent the slop so instead of writing you write the slope provided. Then multiply by the X + b which is your Y-intercept.
Here is an example,
The slope is 2/3 and the y intercept is 6, write a linear equation for this sequence.
y= (2/3). X +6

Carolyn borrowed $38,500 to pay
for college. If the interest rate is
3.2%, how much total will she
have paid after 10 years?
Answers
Answer:
$50820
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.2%/100 = 0.032 per year,
then, solving our equation
I = 38500 × 0.032 × 10 = 12320
I = $ 12,320.00
The simple interest accumulated
on a principal of $ 38,500.00
at a rate of 3.2% per year
for 10 years is $ 12,320.00.

Which of the following equations would be parallel to the line x = 3?
1. y = 3x
2. y = 1
3. y = x
4. x = 5
Answers
Answer:
4. x = 5
Step-by-step explanation:
For two lines to be parallel they must have the same slope, but not be the same line. Both x=3 and x=5 both have slopes of 0, so they are parallel. Another way to tell is that x=3 is a vertical line; therefore, it will be parallel to any other vertical line, such as x=5.

x = 3
x = 4.5
Step-by-step explanation:
A) 2(5x - 3) = 24
5x - 3 = 12 (divide both sides by 2)
5x = 15 (add 3 to both sides)
x = 3 (divide both sides by 5)
B) 5(2x + 1) = 50
2x + 1 = 10 (divide both sides by 5)
2x = 9 (take 1 away from both sides)
x = 4.5 (divide each side by 2)

If using the method of completing the square to solve the quadratic equation x^2-5x-19=0x, which number would have to be added to "complete the square"?
Answers
Answer:
25/4 or 6.25
Step-by-step explanation:
Given that the general equation of a quadratic equation is given as
ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.
Hence given x^2-5x-19=0, to complete the square, we add
(-5/2)^2 to both sides following the illustration given.
This is 25/4 or 6.24

Mr. Tyler buys 4 round-trip tickets from Ft. Lauderdale, Florida, to Toronto, Canada. The total cost is $2,156. How much does each ticket cost? Enter the correct answer in the box
Answers
Answer: $539
Step-by-step explanation:
From the question, we are informed that Mr Tyler bought 4 round-trip tickets from Florida to Canada and that the total cost is $2,156.
The cost of each ticket will then be:
= Total cost of the tickets / Number of tickets
= $2156 / 4
= $539
Therefore, each ticket cost $539
What is the value for x and for y?
Answers
Answer:
20+7x=90
x=10
50+2y=90
y=20
X=10
Y=20
Because a straight line is 180. So 180-20=160 from there you see that one of the angles is a right angle, you can tell this by that it has that little cube in the middle. So 160-90=70 that means that 7x=70 bit you are trying to find for x so divid 70 by 7 that equals 10.
Now to solve for why you have to plug in the information you already know. Vertical angles are congruent. That means that the that the 20 goes straight across and 7x with is actually 70 goes straight across. Now you already know the angle in the middle is 90 but this this it’s split. Since x is 10 multiply 5 by 10 then you get 50 now 90-50=40. 2y is 40 divide it by 2 to get y=20.
I’m bad at explaining so I hope I didn’t confuse you.

A. Based on the graph, the relationship between x and y proportional is a linear relationship.
B. The point (3,90) represents in 3 hours he earns 90 dollars.
D. The linear equation will be
[tex]\begin{aligned} \rm y - 30 &= \rm \dfrac{90-30}{3-1} (x - 1)\\\\\rm y - 30 &= \rm 30x - 30\\\\\rm y &= \rm 30x \end{aligned}[/tex]
C. Based on the graph, the amount of money in dollars will Mr. David earn if he works 10 hours will be
y = 30x
y = 30 × 10
y = $300
