Answer:
a) angle CAR =angle BAR
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
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.

Answer:
[ ] = 3¹³
Step-by-step explanation:
3¹⁷ - 3¹⁵ + 3¹³ = [ ] x 73
3¹³ [3⁴ - 3² + 1] = [ ] x 73
3¹³ [81 - 9 + 1] = [ ] x 73
3¹³ x 73 = [ ] x 73

y=x+1 x-y=1 solve by substitution
Answer:
No Solution
Step-by-step explanation:
You can use the expression for y provided by the first equation to substitute for y in the second equation.
y = x +1
x -(x +1) = 1
-1 = 1
There are no values of the variables x and y that will make this equation true. The system has No Solution.
__
Additional comment
Solving the second equation for y gives ...
y = x -1
This graphs as a line parallel to the line representing the first equation. A system describing parallel lines has no solution, because the lines never meet, and the solution is the point where they meet.
Answer:
no possible answer.
Step-by-step explanation:
1. y = x+1
2. x-y = 1
3. x = 1+y
Substitute equation 3 into the x in equation 1:
y = (1+y)+1
y = 2+y
y-y = 2
0=2
"0 = 2" isn't valid, thus there is no possible answer to this question.

Your friend has a recipe book with 1,000 recipes. She wants to try two new recipes each week. What fraction of the recipes in the book will she have tried after 1 year?
Answer:
104/1000
Step-by-step explanation:
If she tries two each week you will need to know how many weeks are in a year.Now about 52 weeks are in a year so you would multiply 52 by 2 and get 104.
Here, we need to find the fraction of recipes she would have tried in the book after 1 year
The fraction of recipes she would have tried in the book after 1 year is 13/125
Total recipes in the book
[tex] = \frac{Total recipe she tried in a year}{Total recipes in the book } [/tex]
= 1,000
Recipe tried each week = 2
Find the fraction of recipe she would have tried after 1 year
There are 52 weeks in 1 year
she tried 2 recipes each week
Total recipe she tried in a year
=
[tex] = total \: number \: of \: weeks \: in \: a \: year \: \times number \: of \: recipe \: tried \: per \: week[/tex]
[tex] = 52 \times 2[/tex]
[tex] = 104[/tex]
fraction of recipe she would have tried after 1 year
[tex] = \frac{Total recipe she tried in a year}{Total recipes in the book } [/tex]
= [tex] \frac{104}{1000} [/tex]
Divide by 8
= 13/125

Find the curved surface area of a cone with base diameter 30 cm and height 40cm.
Answer:
the diameter of the base is 15cm. Find the curved surface area of cone. Solution: Given that, Slant height: l = 20cm
Slant = root of 30^2 + 40^2 = 50
Curved surface area = pi *r*l
pi*15*50
= 750*pi = 750*3.14

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
