Step-by-step explanation:
I believe we are expected to solve for the number of lawns she would mow before she could make profit
let the cost be C
and let the price be P
and let the number of lawn be x
C=$450----------1
P=6+20x---------2
equating 1 and 2 we can find x
450=6+20x
450-6=20x
444=20x
x=444/20
x=22.2
therefore for her to break even and start making profit she need to mow 22.2 lawns and above

Which hyperbola has one focus point in common with the hyperbola (y+11)^2/(15^2)-(x-7)^2/(8^2)=1
Answer:
3 &4
Step-by-step explanation:
The hyperbola with one focus point in common with the given hyperbola is:
[(y + 11)² / 10²] - [(x - 7)² / 15²] = 1
Which hyperbola has one focus point in common with the given hyperbola?To find a hyperbola that shares one focus point with the given hyperbola, we need to find another hyperbola with the same focus point but different characteristics (e.g., eccentricity or axis length).
The equation of the given hyperbola is:
[(y + 11)² / 15²] - [(x - 7)² / 8²] = 1
The general equation of a hyperbola with its center at (h, k) is:
[(y - k)² / a²] - [(x - h)² / b²] = 1
The center (h, k) of the given hyperbola is (7, -11).
To share one focus point, we need to keep the center at (7, -11) but change the values of a and b. The eccentricity of a hyperbola is defined as e = c / a, where c is the distance from the center to the focus.
Let's assume the new hyperbola has an eccentricity different from the given hyperbola. We'll keep the same value of c and change the value of a to get a different eccentricity.
Let's say the new hyperbola has a value of a' = 10. Since the eccentricity is different, the value of b' will change accordingly. Let's calculate b' using the eccentricity formula:
e = c / a'
15 / 10 = 1.5
Now, we can find b' using the eccentricity:
e = c / a' = c / 10
c = e * a' = 1.5 * 10 = 15
Now, we have the center (7, -11), the value of a' = 10, and the value of c = 15. The equation of the new hyperbola with one focus point in common is:
[(y + 11)² / 10²] - [(x - 7)² / 15²] = 1

Jackson went into a movie theater and bought 8 bags of popcorn and 2 candies, costing a total of $58. Cooper went into the same movie theater and bought 4 bags of popcorn and 5 candies, costing a total of $49. Write a system of equations that could be used to determine the price of each bag of popcorn and the price of each candy. Define the variables that you use to write the system.
Answer:
Jackson: 8p + 2c = 58
Cooper: 4p + 5c = 49
Step-by-step explanation:
p= popcorn
c= candies

Which of the following properties are true for rigid transformations?
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure
O ii only
O i and ii
O ii and in
O i, ii, and in
Answer:
The first choice is correct. ii only.
Step-by-step explanation:
A rigid transformation changes the location of the shape without changing its size. There are three basic rigid transformations: reflections, rotations, and translations.
We are given these properties:
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure.
Let's analyze each choice below:
O ii only . This is true. The other two properties are non-rigid transformations. Correct
O i and ii . This is not true. Increasing or decreasing the size of the figure is a non-rigid transformation. Incorrect.
O ii and iii. Changing the shape of the figure is a non-rigid transformation. Incorrect.
O i, ii, and iii. Properties i and iii are non-rigid transformation. Incorrect.

Im so sorry if im wrong
what is the m∠q ?????????????????????? help i taking a test and imma get beat if i fail
Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
this is an isosceles triangle, which mean that PRQ and PQR are equal.
all sides of a triangle equal 180.
using this, you can make the following equation:
x + (2x + 15) + (2x + 15) = 180
combine like terms
5x + 30 = 180
subtract 30 from both sides
5x = 150
divide both sides by 5
x = 30

Mother is three times as old as her daughter. Three years ago she was four times as old as her daughter was. Find their present ages.
Answer:
daughter = 9yrs
mother = 27yrs
Step-by-step explanation:
let age of daughter be x
age of mother = 3x
by qsn,
three yrs ago,
4 (x-3) = 3x-3
4x-12 = 3x-3
4x-3x = -3+12

Fernando has been saving money to buy an e-book reader. A store has just marked down the price of its readers by 40%. Each reader comes with a mail-in rebate for $25. If the reader used to cost $150, what will Fernando's final price be after the markdown and rebate? The total amount off includes the markdown and rebate. What is the total amount off?
Answer:
$85Step-by-step explanation:
We are expected to solve for the amount off the reader after 40% discount and $25 refund(rebate)
Now given that the book is $150
40% of 150
=(40/100)*150
=0.4*150
=$60
The total amount off includes the markdown and rebate.
the total amount is

HELP ASAP Find the equation of a line that goes through the points (8, -9) and (-4, 15).
Answer:
Your answer is: y= -2x+7
Step-by-step explanation:
Hope this helped : )
The equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7
The formula for calculating the equation of a line is expressed as y = mx+ b
m is the slope of the line
b is the y-intercept
Given the coordinate points (8, -9) and (-4, 15)
Get the slope of the line;
[tex]m =\frac{15-(-9)}{-4-8}\\m=\frac{24}{-12} \\m = -2[/tex]
Get the y-intercept of the line
Recall that y = mx + b
15 = -2(-4) + b
b = 15 - 8
b = 7
Get the required equation in the form y = mx + b
y = -2x + 7
Hence the equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7
