Secant TP and tangent TR intersect at point T Chord SR and chord PO intersect
at point V. Find the values of x and y. If necessary, round to the nearest tenth.
A
x=2
y=4
B. x= 11.6
y = 11.6
C.
X = 11.6
y = 232
D. x = 18.3
y=36.6
Answer:
(C)x=11.6, y=23.2
Step-by-step explanation:
Using Theorem of Intersecting Secant and Tangent
[tex]TQ$ X TP=TR^2[/tex]
[tex]10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6[/tex]
Next, we apply Theorem of Intersecting Chords
PV X VQ=SV X VR
4 X x= 2 X y
Recall: x=11.6
2y=4 X 11.6
2y=46.4
y=46.4/2=23.2
Therefore: x=11.6, y=23.2
The correct option is C

Gabriel started to calculate the area of the triangle. His work is shown. A = 1 2 bh = 1 2 ( 1 2 ) ( 3 4 ) A triangle has a base of three-fourths inch and a height of one-half inch.
Question:
Gabriel started to calculate the area of the triangle. His work is shown.
A = 1/2 bh=1/2 (1/2) (3/4)
A triangle has a base of three-fourths inch and a height of one-half inch
What is the area of the triangle?
The area of the triangle is ___in.²
Answer:
Area of the triangle = [tex] \frac{3}{16} inch^2 [/tex]
Step-by-step explanation:
We are given the dimensions of the triangle as:
Base, b = ¾ inch
Height, h= ½ inch
To find the area of the triangle, let's use the formula :
Area of a triangle = ½base *height
Solving further, we have:
Area of a triangle = [tex] \frac{1}{2}*\frac{3}{4} * \frac{1}{2} = \frac{3}{16} [/tex]
Area of the triangle = [tex] \frac{3}{16} inch^2 [/tex]

Step-by-step explanation:
Tanya has a garden with a trench around it.
Tanya's garden is a rectangle with length [tex]\dfrac12 \text{m}[/tex] and width 2m.
The trench and garden together make a rectangle with length [tex]3 \dfrac12 \text{m}[/tex] and width 3m.
We are to determine the area of just the trench.
Area of just the trench = Area of the trench and garden together-Area of the garden
[tex]=(3 \dfrac12 X 3)-(\dfrac12 X 2)\\\\=( \dfrac72 X 3)-1\\\\=\dfrac{21}{2}-1\\\\=9 \dfrac12 m^2[/tex]
The area of the trench is [tex]9 \dfrac12 m^2[/tex]

Natalie baked 20 cupcakes for a fundraising event at school. On the way to the event she dropped 35% of the cupcakes on the floor. What is the total number of cupcakes that natalie dropped?
Answer:
The total number of cupcakes that Natalie dropped is 7.
Step-by-step explanation:
This question can be solved using a rule of three.
The amount of cupcakes that she has, which is 20, is 100% = 1. How many cupcakes is 35% = 0.35?
20 cupcakes - 1
x cupcakes - 0.35
x = 20*0.35 = 7
The total number of cupcakes that Natalie dropped is 7.

If you have 24 square tiles, how many different rectangles can you make? Each rectangle must use all of the tiles and have no holes or gaps. Sketch each rectangle and label its length and width.
Answer:
4
Step-by-step explanation:
A rectangle has a shorter side and a longer side.
The longer side is called the length and the shorter side is called width.
with the 24 tiles you can make the following rectangles (consider the first number the length and the second number the width, and that each unit represents a tile):
24 x 1
12 x 2
8 x 3
6 x 4
A total of 4 different rectangles.
I am not counting the rectangles than have the same sides shifted, for example 2 x 12 because it is the same as 12 x 2 and we are asked for the rectangles to be different.
I attache an image of the sketch of each rectangle with the labels of length and width (not to scale).

Hey there! I'd be delighted to help you out!
First, let's write down our expression!
[tex](x^2-x)+(8x-2x^2)[/tex]
When we look at this expression, we see that all of the numbers are terms, or numbers that are added. We have four terms in this equation, which are:
[tex]x^2, -x, 8x, -2x^2[/tex]
Now, to simplify, we want to combine like terms. Like terms are numbers that have the same variable (or no variable) and are raised to the same power. 1 and 5 are like terms because they both have no variable and they are both raised to the power of 1 (any number that is itself is raised to this power). 4x and 12x are like terms because they both have an x and a power of 1. 4y and 5x are not like terms because they have different variables. 4x³ and 2x² are not like terms because they are raised to different powers.
Now, we see that with our numbers, x² and -2x² are like terms, and -x and 8x are also like terms. We can combine accordingly.
[tex]x^2-2x^2=-x^2\\\\-x+8x=7x[/tex]
Now we combine to get our simplified expression!
[tex]-x^2+7x[/tex]

Mal is putting money into a savings account. She starts with $350 in the savings account, and each week she adds $30.
Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Mal has been adding money. Write an
equation relating S to W. Then use this equation to find the total amount of money in the savings account after 19 weeks.
Answer:
Mal starts with 350 dollar
Each week she adds $30.
W is number of weeks Mal adds money.
S is total amount of money in her account.
=> S =30W + 350
After W = 19 weeks, Mal will have 30 x 19 + 350 = 920 dollar

Determinar un numero, que disminuido en sus 1/4 partes equivale a su duplo aumentado en 30. Una cuerda de 180m se corta en tres trozos: trozo A B Y C. Calcular cuantos miden los trozos sabiendo que el trozo B y el trozo C miden el doble y el triple que el trozo A, respectivamente.
Answer:
x = 240
A = 30 m, B = 60 m, C= 90 m
Step-by-step explanation:
a) Nosotros debemos determinar un numero;
para cual [tex]\dfrac{1}{4}x = 60[/tex]
[tex]0.25 x = 60[/tex]
Divide ambos lados entre 0.25; tenemos :
[tex]\dfrac{0.25 x}{0.25}= \dfrac{60}{0.25}[/tex]
x = 240
b) A 180 m se corta en tres piezas A, B y C
Entonces;
Si la pieza B y la pieza C miden el doble y el triple de esa pieza A, respectivamente. Entonces; tenemos
x + 2x + 3x = 180
6x = 180
Divide ambos lados entre 6; tenemos:
[tex]\dfrac{6x}{6} = \dfrac{180}{6}[/tex]
x = 30 m
Si A = x = 30 m
B = 2x = 2×30 m = 60 m
C = 3x = 3×30 m = 90 m
Así; A = 30 m, B = 60 m, C= 90 m
Julie conducts an experiment to find the average word length in a book for a 4th grader and a book for a 8th grader. She finds that for the fourth grade book the mean word length is 5 letters with a range of 6 and for the 8th grade book the mean word length is 6 letters with a range of 9. Which statement is true?
A) On average, the book for the 4th grader has longer words.
B) There is not enough information to know if any of the above are true.
C) The word length varies more in the 8th grade book than the 4th grade book.
D) The longest word in the book for the 4th grader is longer than that in the 8th grade book.
Answer: C
Step-by-step explanation: I chose this answer because in 8th graders, their mean is 6 and their range is 9, that’s a difference of 3. But in 4th graders, their mean is 5 and their range is 6, so there isn’t much of a difference for 4th graders. The answer couldn’t be A, B, or D so I came to the conclusion that it’s C. (Sorry if this explanation doesn’t make sense but I hope I got the right answer.)
The true statement is the word length varies more in the 8th grade book than the 4th grade book.
Mean is a measure of central tendency. It is the average of a set of values. For example, if the numbers in a data set are 3,2,10, the mean is (3 + 2 + 10) /3 = 5
Range is the highest number less the least number in a data set. For example, if the numbers in a data set are 3,2,10, the range is 10 - 2 = 7
The mean word length for the fourth grade book is 5. While, the mean word length for the eighth grade book is 6. This means that on average, the average word length of the eighth grade book is greater than the mean word length for the fourth grade book
The range word length for the fourth grade book is 6. While, the range word length for the eighth grade book is 9. These means that either the longest word in the eighth grade book is more than that of the fourth grade book or that the smallest word in the eighth grade book is less than than that in the fourth grade book. This means that the word length varies more in the 8th grade book than the 4th grade book.

5x - 4y = -10
5x - 5y = -5
Answer:
(x,y) = (-6,-5)
Step-by-step explanation:
If you need the explanation let me know.
Answer:
x = -6
y = -5
Step-by-step explanation:
5x - 4y = -10
5x - 5y = -5
__________--
y = -5
5x - 4y = -10
5x - 4(-5) = -10
5x + 20 = -10
5x = -10 - 20
5x = -30
x = -30/5
x = -6

Answer:
10 > v (if you don't trust me, check it yourself. Subsitute v for 10 in the first equation.
Step-by-step explanation:
1) 7 > v - 3
2) add 3 to both sides
3) so 7 plus 3 equals 10
So you basically do this
7 > v - 3 (ad 3 to both sides)
You get 10 > v (which is as simplified as possible)
