Yes, the isosceles triangles are equal to 180 degrees.
We know that isosceles triangles are triangles which have two equal sides. Since the sides are equal, they subtend equal angles as well.
However, the two equal angles subtended by the equal sides and one more angle which is subtended by the third side of the isosceles triangle all add up to a total of 180 degree as we know that the sum of all the angles of a triangle is always equal to 180 degrees.
Hence we can conclude that the isosceles triangles are also equal to 180 degrees like every other triangle.

Which equation is an identity?
A. –3y + 3 = –3y – 6
B. 9 – (2v + 3) = –2v – 6
C. 3w + 8 – w = 4w – 2(w – 4)
D. 7m – 5 = 8m + 7 – m
Answer:
i think B but I’m not 100% sure lol
Step-by-step explanation:
Here’s what I found on this app
3w + 8 - w = 4w - 2(w - 4)
2w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
0 = 0
Answer: C. 3w + 8 – w = 4w – 2(w – 4)
Identity equations are equations that are true no matter what value is plugged in for the variable. If you simplify an identity equation, you'll ALWAYS get a true statement. Learn about identity equations in this tutorial, and then create your own identity equation.
Step-by-step explanation: Algebra.com
a. 11 - (2v + 3) = -2v - 8
Simplify
11 - 2v - 6 = -2v - 8
5 - 2v = -2v - 8
Add 3v to both sides
5 = -8
That's false, so it is not an identity.
b. 5w + 8 - w = 6w - 2(w - 4)
Simplify
4w + 8 = 6w - 2w + 8
4w + 8 = 4w + 8
That's exactly the same on both sides, so it's
an identity.
c. 7m - 2 = 8m + 4 - m
7m - 2 = 7m + 4
Subtract 7m from both sides:
-2 = 4
That's false, so it is not an identity.
d. 8y + 9 = 8y - 3
Subtract 8y from both sides:
9 = -3
That's false, so it is not an identity.
Bill plans to save for a pair of headphones that are 89.00.The sales tax rate is 8% how much will bill need to save
Answer: 96.12
Step-by-step explanation:
The amount that Bill will need to save will be for the cost of the headphones and the sales tax that will be applied. This will be:
= 89 + (8% × 89)
= 89 + (0.08 × 89)
= 89 + 7.12
= 96.12
Therefore, Bill will need to save 96.12.

Each week, Joe earns $75 for tutoring plus $17.50 for each additional hour he tutors. His friend, Maddie earns $56 for tutoring plus $19.50 for each additional hour she tutors. Write an expression that represents the total they make altogether after tutoring for t hours.
Answer:
$75 + $17.50t
$56 + $19.50t
Step-by-step explanation:
Let us assume the number of hours be t
Now according to the equation
For Joe
= $75 + $17.50t
And, for Maddie
= $56 + $19.50t
The expression that represents the total is as
$75 + $17.50t
$56 + $19.50t
Hence, the above represent the answer and the same is relevant

Macy has 8 quarters and 24 pennies in her pocket. What is the answer that correctly shows the ratio of this comparison? ANSWER PLS
Given:
Macy has 8 quarters and 24 pennies in her pocket.
To find:
The answer that correctly shows the ratio of this comparison.
Solution:
We know that,
Number of quarters = 8
Number of pennies = 24
The ratio of this comparison is:
[tex]Ratio=\dfrac{Quarters}{Pennies}[/tex]
[tex]Ratio=\dfrac{8}{24}[/tex]
[tex]Ratio=\dfrac{1}{3}[/tex]
[tex]Ratio=1:3[/tex]
Therefore, the required ratio is 8:24 and its simplified form is 1:3.

Answer:
180-80=100
100-38=62
MJL=62
angle(m)=80
Answer:
<MJL = 62°
<m = 80°
x = 4
Step-by-step explanation:
in ∆JKL total angle aum is 180° and to find <L we have to subtract the given angles in this triangle from 180
that is
<L = 180-80-38 = 62°
then <MJL = 62° (alternative interior angle)
<JLM= 38° (alternative interior angle)
then <m = 180-62-38 = 80°

In a school of 464 students, 89 students are in the band, 215 students are on sports teams, and 31 students participate in both activities. How many students are involved in neither band nor sports?
A.160 students
B.191 students
C.249 students
D.433 students
Answer:
191 students B option is correct
Step-by-step explanation:
Total students=464
In band=89
sports teams=215
Number of students who participates in activities is
215+89=304
31 participate in both activities so,
304-31=273
273 who participate in activities
Total students-273=Not involved in any activity
464-273=191

Step-by-step explanation:
The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256
What is an inequality?An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let m represent the number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain.
Hence:
(48/2)m < 256
24m < 256
The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256

month?
b. Is there a proportional relationship between time and the cost of the cell phone plan?
Explain how you know.
c. What is the total cost for x months? (Write an equation for the situation.)(help ASAP pleassseeee)
Step-by-step explanation:
a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?
answer for a: $95 + $55 = $150
b. Is there a proportional relationship between time and the cost of the cell phone plan?
answer for b: There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55.
c. What is the total cost for x months? (Write an equation for the situation.)
answer for c: 95 + 55x = y
