If degree measures of the angles of A ABC are represented by 3x, x+10,
and 6x, then A ABC must be...
Answer:
30degrees
Step-by-step explanation:
The sum of angles of a triangle is 180
<A + <B + <C = 180
Substitute the given values
3x + x+10 + 6x = 180
10x + 10 = 180
10x = 180-10
10x = 170
x = 170/10
x = 17
Get <A:
<A = 3x
<A = 3(10)
<A = 30degrees
Hence the measure of angle A is 30degrees

What is the sum of 2x+1 and its opposite?
Answer:
Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined . In this case, the opposite of 2x+1 is -(2x+1)=-2x-1 by the distributive property . Adding like terms, 2x+-2x+1+-1=0+0=0.
4/5 + v = 41/20
solve this plz and show me how you got the answer
Answer:
v = 1 1/4 (1.25)
Step-by-step explanation:
4/5 + v = 41/20
16/20 + v = 41/20
16/20 16/20
---------------------------
v = 41/20 - 16/20 = (41-16)/20 = 25/20 = 5/4 = 1 1/4

Answer:
(4n^2 + 1) (2n+1) (2n-1)
Step-by-step explanation:
use difference of squares
if my answer is correct, pls mark this is brainliest! thanks!
Since both terms are perfect squares, factor using the difference of squares formula,
a² − b² = (a + b) (a − b) where a = 4n² and b=1.
(4n² + 1) (2n + 1) (2n − 1)
its just a riddle tho i need it for math plz answer the riddle ill give brainliest
Answer:
Area Rugs
Step-by-step explanation:
Select ALL the correct answers,
Select the scenarios that correctly represent the given graph
1. The amount of money in an account decreases for a few months and then increases.
2. The height of a stone shot by a catapult reaches a maximum height and then falls on the ground.
3. The sale of a product increases at first and then decreases.
4. The radioactivity of a substance decreases by 10% every year.
5. The speed of a car increases constantly by 10 miles per hour.
Option (2) and Option (3) is the correct answer .
Required Explaination :
Scenario 2 : The height of a stone shot by a catapult reaches a maximum height and then falls on the ground.
The graph of this scenario is a downward parabola. Therefore option 2 is correct.Scenario 3 : The sale of product increases at first and then decreases.
The graph of this scenario is a downward parabola. Therefore option 3 is correct.Therefore, the correct options are 2 and 3.

write an expression that can be usedto find the nth termo of each sequence 9, 17, 25, 33
Answer:
The expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
[tex]a_n=8n+1[/tex]Step-by-step explanation:
Given the sequence
9, 17, 25, 33
a₁ = 9
Determining the common difference
d = 17-9 = 8
d = 25-17 = 8
d = 33-25 = 8
As the common difference between the adjacent terms is same and equal to
d = 8
Therefore, the given sequence is an Arithmetic sequence.
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = 9, d = 8 in the equation
[tex]\:a_n=9+8n-8[/tex]
[tex]a_n=8n+1[/tex]
Therefore, the expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
[tex]a_n=8n+1[/tex]Dan brought 36 vanilla cupcakes and 49 chocolate cupcakes to his school bake sale. Then his friend brought 5 more cupcakes. How many total cupcakes did the bake sale have to sell?
Answer:
90
Step-by-step explanation:
Answer:
90 cupcakes
Step-by-step explanation:
So, to solve this question all we have to do is add the number of cupcakes that Dan brought and the number of cupcakes that his friend bought.
So the expression would look like this:
36 + 49 + 5 = 90
So, in conclusion, the bake sale had 90 cupcakes to sell

Answer:
C. 65
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
180-62-53 = 65
3 Prove that
cos130°+cos 110+ cos10=0
We know, cos A + cos B = 2cos(C+D)/2 × cos(C - D)/2
So,
cos 130 + cos 110 + cos 10
cos 130 + 2cos (110+10)/2 × cos( 110-10)/2
cos 130 + 2cos 60 × cos 50
cos ( 180 - 50 ) + 2cos60 cos 50
We know, cos ( 180 - A ) = -cos A
2cos 60 cos 50 - cos 50
Also, cos 60 = 0.5
2×0.5 cos 50 - cos50
cos 50 - cos 50
0 = RHS.
Hence proved
