Answer:
Angle 1: 95 degrees
Angle 2: 85 degrees
Angle 3: 95 degrees
Step-by-step explanation:
Vertical angles are opposite and equal so in this case angle 1 and 3 are vertical and so are 2 and 85°
So that means angle 2 also equals 85 degrees and because of supplementary angles the other angle must add up to equal 180 degrees
85 + ? = 180
?=95
So both angle 1 and 3 equal 95 degrees
f varies inversely as the square of d. When d=2, f = 6. Find d when f is 1.5
Answer:
d = 4
Step-by-step explanation:
Given f varies inversely as d² then the equation relating them is
f = [tex]\frac{k}{d^2}[/tex] ← k is the constant of variation
To find k use the condition when d = 2, f = 6 , then
6 = [tex]\frac{k}{2^2}[/tex] = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )
24 = k
f = [tex]\frac{24}{d^2}[/tex] ← equation of variation
When f = 1.5 , then
1.5 = [tex]\frac{24}{d^2}[/tex] ( multiply both sides by d² )
1.5d² = 24 ( divide both sides by 1.5 )
d² = 16 ( take the square root of both sides )
d = [tex]\sqrt{16}[/tex] = 4
find the median 60,62,64,54,56,28
Answer:
58
Step-by-step explanation:
you need to order all the numbers together:
28, 54, 56, 60, 62, 64
since the middle 2 are 56 and 60 you need to find the average of those.
(56 + 60)/2 = 58
Maddie does not have any pretzels.
Zach gives abbey 8 pretzels. then he splits half the pretzels he has left with Maddie. Zach let's p represent the number of pretzels he starts with. He finds that the number of pretzels maddie has is 1/2 the difference of p and 8.
write an expression to represent the number of pretzels that maddie has.
Answer:
(p - 8) / 2 = Maddie's pretzels

tell me 3 mathematical things that you know in relation to geometry
Answer:
Dilations which reduce or enlarge an object. Translations which move the object from one part on the graph to another. I have also learned about how to construct a perpendicular bisector.
Step-by-step explanation:
====================================
Geometry is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things.====================================
--> Actually, Flat shapes like squares, circles, and triangles are a part of flat geometry and are called 2D shapes.
These shapes have only 2 dimensions, the length and the width.
( based on what i know )
M<1 and m<2 are vertical angles if m<1 = 106° and M<2 equals 20x - 14 find M<2
Answer:
Answer:
m∠2= 86
Step-by-step explanation:
since they are vertical angles, that means they are both equal to eachother.
so lets set them equal!
17x+1=20x-14
17x+15=20x
15=3x
x=5
now input x into m∠2
m∠2 = 20(5) – 14 = 86

Solve for side c and round to the nearest tenth
Answer:
c
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan64° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{11}{c}[/tex] ( multiply both sides by c )
c × tan64° = 11 ( divide both sides by tan64° )
c = [tex]\frac{11}{tan64}[/tex] ≈ 5.4 ( to the nearest tenth )
Solve for X (In the Diagram)

Trisha borrowed money from her mom to buy a skateboard plus safety gear. She paid back a little bit of money every week.
After 3 weeks she owed her mom $281. After 8 weeks, she owed her mom $166. Let y represent the amount she owes her mom and x represent the number of weeks she has been paying her debt.
Write an equation in slope-intercept form to represent how much she owes her mom after x weeks.
y=
How much money is Trisha paying her mom each week? $
How long will it take Trisha to pay off her debt?
weeks (answer in whole weeks)
Answer:
y==$281+$166=$447
in 11 weeks she pay $ 447
in 1 weeks she pay $447/11=40.6$
she paid off in 3+8=11 weeks

What is the amplitude of the function f(x)= 6sin(3x)?
Answer:
6
Step-by-step explanation:
The function is of the form
y =a f(bx) where |a| is the amplitude and b is the frequency
y = 6 sin (3x)
The amplitude is |6| = 6
Change the subject from y to x
y = (2x + 1)/(3x + 4)
y(3x + 4) = (2x + 1)
3xy + 4y = 2x + 1
4y - 1 = 2x - 3xy
4y - 1 = x(2 - 3y)
x = (4y - 1)/(2 - 3y) , answer = E
Find the area of a pizza with
a 16 in. diameter. If there
are 8 slices, how many sq. in.
is one slice?
Answer:
area of whole pizza = 200.96 in²
area of slice of pizza = 25.12 in²
Step-by-step explanation:
16"/2 = 8" radius
area = πr² = (3.14)(8²) = 200.96 in²
200.96 in²/8 = 25.12 in²

Answer:
y - 9 = -3/2 (x - 6)
Step-by-step explanation:
Equation of line: 4x - 6y - 15 = 0
Equation of perpendicular line: bx - ay + k = 0
= -6x - 4y + k = 0 → (equation 1)
Since the equation passes through (6,9)
-6(6) - 4(9) + k = 0
-36 -36 + k = 0
-72 + k = 0
k = 72
Substituting the value of in equation 1,
∴ Equation of perpendicular line = -6x -4y + 72 = 0
dividing by -2,
3x + 2y - 36 = 0
This equation is the simplified version of Option 1.
y - 9 = -3/2 (x - 6)
y - 9 = (-3x + 18)/2
2y - 18 = -3x + 18
3x + 2y - 36 = 0
In the last 4 seasons, Luis scored 14,18, 15, and 25 goals. How many goals does he need to score this year, to end the season with an overall average of 20 goals per season? O A. 29 O B. 27 O C. 30 O D. 28
Answer:
28
Step-by-step explanation:
For Luis to get a mean of 20 he would need:
14 + 18 + 15 + 25 + x (unknown number of goal he needs) / 5 = 20
Therefore 14 + 18 + 15 + 25 + x = 100
Solve for x to get 28
Plot and connect the points A (3, -3), B (-3, -2), C (-5, 1), D (-5, 4), E (-4 ,6), F (-2, 6), G (3, 2), and find the length of EF.
Given:
The points are A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2).
To find:
The length of EF and plot each point on a coordinate plane and connect them.
Solution:
Plot the given point A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2) on coordinate plane and connect them as shown in the below figure.
From the below graph it is clear that the length of EF is 2 units. We can verify this solution by using the distance formula.
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between E(-4 ,6) and F(-2, 6) is
[tex]D=\sqrt{(-2-(-4))^2+(6-6)^2}[/tex]
[tex]D=\sqrt{(-2+4)^2+(0)^2}[/tex]
[tex]D=\sqrt{(2)^2+0}[/tex]
[tex]D=2[/tex]
Therefore, the length of EF is 2 units.
a national park is a rectangle that is 33 miles wide and 56 miles long.how long is a diagonal road through the park
9514 1404 393
Answer:
65 miles
Step-by-step explanation:
The Pythagorean theorem applies.
d^2 = 33^2 +56^2
d^2 = 1089 +3136 = 4225
d = √4225 = 65
The diagonal road is 65 miles long.
