Answer:
discount rate= 0.35
Step-by-step explanation:
Giving the following information:
The price on the tag was $20, but Lauren paid $13 before tax.
To calculate the discount rate, we need to use the following formula:
Total discount= total price * ( 1 - discount rate)
13= 20 * (1 - discount rate)
13= 20 - 20discount rate
20discount rate = 7
discount rate= 7 / 20
discount rate= 0.35

The heights of the mountains in a mountain range are less than 20,000 feet. Write an inequality to represent the heights of the mountains, h, in this mountain range.
Answer:
D, far apart from each other.
Step-by-step explanation:
The inequality that represent the heights of the mountains in the given range is h < 20,000
What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
Given that, the heights of the mountains in a mountain range are less than 20,000 feet.
We need to write an inequality to represent the height of the mountain ranges,
Since, the height is less than 20,000,
Therefore, the inequality =
h < 20,000
Hence, the inequality that represent the heights of the mountains in the given range is h < 20,000

The mean age of 5 people in a room is 31 years.
A person enters the room.
The mean age is now 30.
What is the age of the person who entered the room?
Answer:
25 year
Step-by-step explanation:
Mean = sum/no. *of observations
Initially, number of people = 5 & let the sum of their ages be S.
=> 31 = S/5
=> 155 = S
When one more entered, number = 6. Let his age be 'a'.
Sum of ages = S + a = 155 + a
=> 30 = (155 + a)/6
=> 180 = 155 + a
=> 25 = a

Parallel lines problem:
Parallel lines have the same slope, so the answer should give a pair of lines whose slope is equal to that of line m, i.e., 2/3.
The only line that fits the bill is line p, whose slops is (8-6)/(12-9) = 2/3; none of the other lines has a slope of 2/3. Thus, b would be the correct answer here for the first image.
Congruent triangles problem:
Segment ZX and angle Y would be congruent to segment SQ and R, respectively, so the correct answer for the second image would be a.

Which of the following equations is true to find the length BC?
Answer:
BC/sin 23 = 10/sin 47
Step-by-step explanation:
Here, we want to select the true equation to find the length BC
From the question, we have the angle facing side BC; also, we have the angle and the side facing it for another side
In this situation, the best way to solve for BC is by the use of the sine rule
The sine rule states that the ratio of the length of a side and the sine of the angle facing the side is constant for a given triangle
Thus, we have it that;
BC/sin 23 = 10/sin 47

use the distance formula to find the distance between the two points (-3, 3) and (2, 2) give the exact length (leave in radical form if it is not a perfect square). but please show your work so i can understand. its ok if u cant show ur work tho thank you!
Answer:
[tex]\sqrt{26}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (2, 2)
d = [tex]\sqrt{(2+3)^2+(2-3)^2}[/tex]
= [tex]\sqrt{5^2+(-1)^2}[/tex]
= [tex]\sqrt{25+1}[/tex]
= [tex]\sqrt{26}[/tex]

1) What is the product of (3x + 2) and (x - 7)?
2) What are the factors (multiplier) of 3x2 − 9x ?
Answer both of the questions
Answer:
1) [tex]3x^{2}[/tex]-19x-14
2) x=0, x=3
Step-by-step explanation:
1) (3x+2)(x-7)
Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.
[tex]3x^{2}[/tex] - 21x + 2x -14
Combine like terms
[tex]3x^{2}[/tex] - 19x - 14
2)
In order to find the factors of x, set the expression equal to 0.
[tex]3x^{2}[/tex] - 9x = 0
Factor out the highest common multiple (3x)
3x(x-3) = 0
In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3
Or 3x = 0 -> x = 0
Hope this helps!

cosθ > 0 in quadrants I and IV
cotθ < 0 in quadrants II and IV

A quadratic function is represented by the graph. (graph below.) (do a-d.)
(a) What is the equation of the axis of symmetry of the function?
(b) What are the coordinates of the vertex of the function?
(c) What are the coordinates of the x-intercepts of the function?
(d) What are the coordinates of the y-intercept of the function?
Answer:
The axis of symmetry is x=1
The vertex is (1,-9)
The x-intercepts are (4,0) and (-2,0)
The y-intercept is (0,-8)
Step-by-step explanation:
axis of symmetry is the line where the vertex is, so in the quadratic of x^2, the axis of symmetry would be zero because half of the equation is on one side and the other half on the other side
The vertex is the lowest point on the quadratic, on the y values
the x-intercepts are the places the graph intercepts the x-axis.
The y-intercepts are the places the graph intercepts the y-axis

Answer:

Step-by-step explanation:
110+6x=386
Answer: 46 times
Step-by-step explanation:
Since $110 is the constant and 6 is the coefficient because it is changing with each time he rents a tennis ball. The equation is 110+6t=386 where t in this case can represent (return groundstrokes)
110+6t=386 solve for t
6t=276
t=46
So he can return ground strokes 46 times
