If a ∥ b and m∠1 = 65°, what is m∠2?
Answer:
65 degrees
Step-by-step explanation:
the angles are corresponding, and corresponding angles always have the same angle measures
If a ∥ b and m∠1 = 65°, The measure of m∠2 will be 65°.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle." when a transverse line crosses two straight lines, corresponding angles are formed.
When two lines are crossed by a third line, these angles are generated at equivalent corners or corners corresponding to the transversal.
It is given that, a ∥ b and m∠1 = 65.
If the transversal meets two parallel lines, the corresponding angles theory asserts that the corresponding angles are congruent. In other words, the angles formed when a transversal crosses two parallel lines will always be equal.
Since corresponding angles always have the same angle measures, the angles are said to be corresponding.
As a result,
m∠1 =m∠2
m∠1 = 65°
m∠2=65°
Thus, if a ∥ b and m∠1 = 65°, The measure of m∠2 will be 65°.

what is angle ecb? (rhombus)
==================================================
Explanation
The diagonals of a rhombus are always perpendicular.
This leads to triangle ECB being a right triangle. The 90 degree angle at point E.
The other acute angles add to 90
C+B = 90
(5a+4) + (8a-5) = 90
13a-1 = 90
13a = 90+1
13a = 91
a = 91/13
a = 7
This value then leads to:
angle ECB = 5a+4 = 5*7+4 = 35+4 = 39 degreesangle CBE = 8a-5 = 8*7-5 = 56-5 = 51 degreesNote how 39+51 = 90 to confirm that C+B = 90 is correct. This confirms the correct 'a' value and final answer.

Kelly is on a four-person relay team. The team's total time for its last race was 41.37 seconds. Giselle ran her part in 9.36 seconds. Sarah took 9.71 seconds to run her part of the race, and Aliyah ran her part in 10.57 seconds. How long did Kelly take to run her portion of the race?
Answer: 11.73 seconds
Step-by-step explanation:
To solve the question, we have to add the time used by Giselle, Sarah and Aliyah and then subtract from 41.37 seconds to determine the time used by Kelly. This will be:
= 41.37 - (9.36 + 9.71 + 10.57)
= 41.37 - 29.64
= 11.73 seconds
Kelly used 11.73 seconds

card after the purchase. If the DVDs were all the same price, which inequality best represents the possible price of each
DVD?
Answer:

Rhonda went out to dinner.
• The price of her meal was
$15.55.
• The sales tax was 7% of the
price of the meal.
• The tip was 18% of both the
meal and the sales tax.
How much money did Rhonda
pay for the meal, including tax
and tip?
Answer:
18.54
Step-by-step explanation:
15.55 X 7% = 1.0885
15.55 + 1.0885 = 16.6385 X 18% = 2.99493
15.55 + 2.99493 =18.54493
Stamps can be brought in a book of 20. how many books will a customer need to mail 50 invitations
Answer:
2.5
Step-by-step explanation:
All you have to do to figure this out is divide your 50 invitations by twenty stamps because there is 20 stamps in one booklet. 50 divided by 20=2.5
Answer:
3 books
Step-by-step explanation:
Assuming that you cannot buy a partial book of stamps, you would have to buy a surplus in order to obtain (at least) 50 stamps. That is because 50 is not a multiple of 20.
In theory you would need 2.5 books of stamps, but that half-book should be counted and rounded up to three. You wouldn't have sufficient stamps if you buy only 2 books.

Carlos builds a robot that moves on small wheels. Each wheel has six 5-inch-long metal spokes that meet in the center. What the length of an arc between two consecutive spokes?
Express your answer as a simplified fraction in terms of \piπ.
The length of an arc between two consecutive spokes is 5π/8 in.
Length of an arc
The length of an arc L = rФ where
r = radius of circle = 5 in/2 = 2.5 in and Ф = angle subtended by arc in radians = 2π/n where n = number of sectors in circle = 8So, L = rФ
L = r × 2π/n
L = 2πr/n
Substituting the values of the variables into the equation, we have
L = 2πr/n
L = 2π × 2.5 in/8
L = 5π/8 in
So, the length of an arc between two consecutive spokes is 5π/8 in.

Which relationship would form a graph that is not a straight line?
Answer:
D
Step-by-step explanation:
The last line is not a straight line because when you start from 1 and plug higher numbers, you see that forms a quadratic curve or parabola.
Write a quadratic function.
Answer:
[tex]\displaystyle y = x^2 + 6x + 12[/tex]
Step-by-step explanation:
To begin with, to define the stretch factour [tex]\displaystyle [A],[/tex]from the standard quadratic equation of [tex]\displaystyle y = Ax^2 + Bx + C,[/tex]find the rate of change between the vertex of [tex]\displaystyle [-3, 3][/tex] and either [tex]\displaystyle [-4, 4][/tex]or [tex]\displaystyle [-2, 4].[/tex]It really does not matter which ordered pair you choose to pair with the vertex because one result will be negative, and the other result will be positive, so it is as though you are taking the absolute value of the rate of change, but not entirely. Anyhow, let us get to wourk:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-4 + 3}{2 - 3} \hookrightarrow \frac{-1}{-1} \\ \\ 1 = m[/tex]
OR
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-4 + 3}{4 - 3} \hookrightarrow \frac{-1}{1} \\ \\ -1 = m[/tex]
So, both oppocite rate of changes tell you that the stretch factour of this quadratic function is [tex]\displaystyle 1,[/tex]ESPECIALLY sinse the graph opens upward.
Now, to determine the quadratic equation for this graph, you need to write this in vertex form first. Remember to base the equation off the vertex:
[tex]\displaystyle y = A[x - h]^2 + k \\ \\ y = [x + 3]^2 + 3[/tex]
So, −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, and sinse the vertex [tex]\displaystyle [(h, k)][/tex]is at [tex]\displaystyle [-3, 3],[/tex]there MUST BE a plus sign inside those brackets. Anyway, let us continue:
[tex]\displaystyle y = [x + 3]^2 + 3 \hookrightarrow y = x^2 + 6x + 9 + 3 \\ \\ \boxed{y = x^2 + 6x + 12}[/tex]
You now have your quadratic equation.

8) Imani spent half of her weekly allowance
playing mini-golf. To earn more money her
parents let her wash the car for $4. What is
her weekly allowance if she ended with
$12?
how would i solve this in a two step equation? pls and thanks
Answer:
See below.
Step-by-step explanation:
We can represent Imani's weekly allowance with the variable a. The equation you can write is:
1/2a+4=12
2(1/2a+4)=2(12)
a+8=24
a=16
The Imani's weekly allowance value is $16.
To solve this problem using a two-step equation, follow these steps:
Step 1: Let's represent Imani's weekly allowance with the variable "x."
Step 2: We know that Imani spent half of her allowance playing mini-golf, so the amount she spent is (1/2) × x. Additionally, she earned $4 by washing the car. Therefore, the equation becomes:
x - (1/2) × x + 4 = 12
To solve this equation, we need to combine like terms and isolate the variable "x":
(1/2) ×x = 12 - 4
(1/2) × x = 8
Next multiply both sides of the equation by 2 to eliminate the fraction:
2 × ((1/2) × x) = 2 × 8
x = 16

The area of a circle is 16π m². What is the circumference, in meters? Express your answer in terms of pi
*hint 8 isnt the answer *
brainlest
pls hurry
Solution:
We know that:
Area of circle = πr² = 16π
Let's undo this equation by dividing π both sides. Then, take a square root to find the radius.
=> πr² = 16π=> πr²/π = 16π/π=> r² = 16=> √r² = √16=> r = 4Now, let's find the circumference by substituting the radius in the circumference formula.
=> 2πr = Circumference=> (2)(π)(r) = Circumference=> (2)(π)(4) = Circumference=> 8π meters = CircumferenceSince the question says to leave the circumference in terms of π, 8π meters is the circumference of the circle.
Thus, the circumference is 8π meters
