You are building a shelf that fits in a corner. In the figure, the entire shelf is △XYZ. Each unit in the coordinate plane represents one inch.

Answers

Complete Question: You are building a shelf that fits in a corner in the figure the entire shelf is XYZ each unit in the coordinate plane represents one inch find the area of the shelf.

Answer:

112.5 units²

Step-by-step explanation:

Area of the shelf = ½*base*height.

The base is the distance between Z(0, 5) and Y(15, 5)

The height is the distance between X(15, 20) and Y(15, 5).

Therefore area of the shelf = ½*ZY*XY

Use the distance formula to find ZY and XY.

Distance between Z(0, 5) and Y(15, 5):

[tex] ZY = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] Z(0, 5) = (x_1, y_1) [/tex]

[tex] Y(15, 5) = (x_2, y_2) [/tex]

[tex] ZY = \sqrt{(15 - 0)^2 + (5 - 5)^2} [/tex]

[tex] AB = \sqrt{(15)^2 + (0)^2} [/tex]

[tex] AB = \sqrt{225 + 0} = \sqrt{225} [/tex]

[tex] AB = 15 [/tex]

Distance between X(15, 20) and Y(15, 5):

[tex] XY = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] X(15, 20) = (x_1, y_1) [/tex]

[tex] Y(15, 5) = (x_2, y_2) [/tex]

[tex] XY = \sqrt{(15 - 15)^2 + (5 - 20)^2} [/tex]

[tex] XY = \sqrt{(0)^2 + (-15)^2} [/tex]

[tex] XY = \sqrt{0 + 225} = \sqrt{225} [/tex]

[tex] XY = 15 [/tex]

Area of shelf = ½*15*15 = ½*225 = 112.5 units²

A new car is purchased for 22400 dollars. The value of the car depreciates at 11% per year. To the nearest tenth of a year , how long will it be until the value of the car is 5000 dollars?

Answers

Answer:

t= 12.9 years

Step-by-step explanation:

Value after t years = initial value ( 1 - r )^t

Where,

Value after t years= $5000

Initial value = $22,400

r= depreciation rate = 11%

t= length of time (years)

Value after t years = initial value ( 1 - r )^t

5000 = 22,400 ( 1 - 0.11)^t

5000 = 22,400(0.89)^t

Divide both sides by 22,400

(0.89)^t = 5000 / 22,400

(0.89)^t = 0.2232

Take the log of both sides

t log 0.89 = log 0.2232

t= log 0.2232 / log 0.89

= -0.6513 / -0.0506

= 12.87

t= 12.9 years

Priya and Tyler are discussing the figures shown below. Priya thinks that B, C, and D are scaled copies of A. Tyler says B and D are scaled copies of A. Do you agree with Priya, or do you agree with Tyler? Explain your reasoning.

Answers

Answer:

Neither Priya nor Tyler is correct. Both are wrong.

Step-by-step explanation:

Figure D is the only shape that we can refer to as a scaled copy of figure A. This is because, from observation, all segments that make up figure D are times two of the corresponding segments that make up figure A.

Whereas, if we compare figure B, and C with figure A, not all of their segments is twice as the corresponding segments of figure A.

Therefore, both Priya and Tyler are wrong. We cannot agree with any of them.

Answers

Answer:

b. there are no exceptions, because all of the statements above are true.

Step-by-step explanation:

Hypothesis testing refers to the method which is used to test the outcomes of the hypothesis. The result of the experiment conducted is analyzed whether or not the desired results are found. It helps in justifying and finding conclusions in the absence of the scientific theories about the conclusions. A null hypothesis is to be known by the individual before performing the Hypothesis testing.

Sam is 3 times older than her brother, Owen. In 5 years, Sam will be twice as old as Owen. How old are they now?

Answers

Answer:

Sam is 15; Owen is 5.

Step-by-step explanation:

Let s denote Sam's age and let o denote Owen's age.

So, Sam is three times older than Owen. Thus:

[tex]s=3o[/tex]

In 5 years, Sam will be twice as old as Owen. In other words, Sam's current age plus 5 years will be Owen's current age plus five years times 2. Thus:

[tex]s+5=2(o+5)[/tex]

We have a system of equations. Solve for substituting the first equation into the second. Thus:

[tex]3o+5=2(o+5)[/tex]

Distribute the right:

[tex]3o+5=2o+10[/tex]

Subtract 2o from both sides:

[tex]o+5=10[/tex]

Subtract 5 from both sides:

[tex]o=5[/tex]

So, Owen is currently 5 years old.

Sam is 3 times older than Owen, so Sam is 15 years old.

The square root of 19 is an irrational number between 4 and 5.

1. How do you know it's irrational?

2. How do you know it's between 4 and 5?

Answers

1.) you know that 19 is irrational because it is not divisible by any number except 1 and 19 (itself)
2.) you know it’s between 4 and 5 because 4x4=16 and 5x5=25. The square root of 16 is 4 and the square root of 25 is 5. 19 is between 16 and 25; therefore it has to be between 4 and 5.

A square has an area of 172 ftLaTeX: ^22 . What is the approximate length of each side of the square to the nearest tenth?

Answers

Answer:

13.1 feet

Step-by-step explanation:

Area of a square = Length * Length

A = L²

Given the area of a square to be 172ft², to get the approximate length of each side of the square, we will substitute the area given into the formula above and calculate the value of L as shown;

[tex]A = L^2\\\\172 = L^2\\\\L^2 = 172\\\\[/tex]

take the square root of both sides;

[tex]\sqrt{L^2} = \sqrt{172} \\\\L = \sqrt{172} \\\\L = 13.11 ft\\\\L \approx 13.1ft[/tex]

Hence the  approximate length of each side of the square to the nearest tenth is 13.1 feet

=====================================================

Explanation:

The number of points goes down by 1 each time.

The first figure has 4 points on the circle. The second figure has 3 points, and after that is 2 points. So the fourth figure is mostly likely to have 1 point on the circle.

The next step in the circular series is Option C with a point on the circle

What is a Circle?

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the first figure be represented as A

A = figure with a rectangle with 4 points on the circle

Let the second figure be represented as B

B = figure with a triangle with 3 points on the circle

Let the third figure be represented as C

C = figure with a line with 2 points on the circle

Let the next series be represented as D

where D should have only 1 point on the circle

Hence , the figure is Option C with a point on circle

If ST=19 and S lies at -4 , where could T be located?

Answers

Answer:

15 or -23

Step-by-step explanation:

I think you probably already turned this in but in case you haven't:

ST = 19 means that line segment ST is 19 units long. If we know that S is at -4, then T has to be 19 units away from -4, right?

So there's two directions we could go.

Add 19 to -4 to get 15, so T could be at 15. (If there's a line drawn between -4 and 15, it would be 19 units long.)

But the line could go left, towards negative infinity, too. So if we subtract 19 from -4, we'd get -23. T could also be at -23. (If there's a line drawn between -4 and -23, it would also be 19 units long. There's no such thing as a negative length.)

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

A student can read 7 pages of a book in 10 minutes.

Let's suppose the student read x number of pages in 30 minutes.

Mathematically,

7 pages → 10 minutes

x pages →  30 minutes

7/x = 10/30

7/x = 1/3

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

x = 7×3

x = 21 pages

Thus, the student read 21 pages in 30 minutes if the student can read 7 pages of a book in 10 minutes.
