Step-by-step explanation:
HERE,
angle A=x+5
angle B=3x
angle C=x
we know that,
sum of three angle of a triangle =180°
According to the question,
[tex]\tt{ x+5+3x+x=180 }[/tex]
[tex]\tt{5x+5=180 }[/tex]
[tex]\tt{ 5x=180-5 }[/tex]
[tex]\tt{5x=175 }[/tex]
[tex]\tt{ x=\dfrac{175}{5} }[/tex]
[tex]\tt{x=35 }[/tex]
So,
[tex]\bold{\angle{B}=3x=3×35=105° }[/tex]

A cone has a diameter labeled twelve centimeters and a height labeled thirty-two centimeters. Find the area of a vertical cross section through the center of the base of the cone.
Answer:
[tex]A=0.0192[/tex]
Step-by-step explanation:
Diameter labeled twelve centimetres D =12cm => 0.12
height labeled thirty-two centimetres H= 32cm => 0.32
Generally the vertical cross section of this cone is a triangle
Mathematically solving
Area of vertical cross section through the center of the base of the cone is given by [tex]A=1/2 D*height[/tex]
[tex]A=R*H[/tex]
Therefore
[tex]A=\frac{0.12}{2} *0.32[/tex]
[tex]A=0.06 *0.32[/tex]
[tex]A=0.0192[/tex]

Answer:
A circle is a shape.
Step-by-step explanation:
In geometry circles are known for you to solve the radius wit the formula A= π r^2
A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

Easy points, please just enter a random answer or repeat the answers.
If it's hard to see the answers are Pythagorean Theorem, rearrange the previous statement, Pythagorean Theorem, and Expand (b-x)2
Answer:
1) a2 = h2 + x2
✔ Pythagorean theorem
2) h2 = a2 - x2
✔ Rearrange the previous statement
3) c2 = h2 + (b-x)2
✔ Pythagorean theorem
4) c2 = h2 + b2 -2bx + x2
✔ Expand (b – x)2
Step-by-step explanation:
The Pythagorean Theorem could be represented mathematically as follows, Here, c represents the length of the hypotenuse (the longest side), or b or a are the lengths of the other 2 sides. From the equation, you can easily find the value of the 1 side if you have the values of the other 2
1) a2 = h2 + x2
Pythagorean theorem
2) h2 = a2 - x2
Rearrange the previous statement
3) c2 = h2 + (b-x)2
Pythagorean theorem
4) c2 = h2 + b2 -2bx + x2
Expand (b – x)2

Denzel buys a basketball for $24 plus 7.5% tax. Mel buys a football for $20 plus 8% tax. What is the difference in the amount Dave and Mel paid, including tax?
Answer:
Dave paid $4.20 more than Mel
Step-by-step explanation:
Lets start with Dave:
Turn the % into a decimal - so 7.5 % would be 0.075
Then multiply it to the amount in cost to get the tax - 24 x 0.075 = 1. 80
Now add the tax to the total - 24 + 1.8 = $25. 80
Mel
Turn the % into a decimal - so 8 % would be 0.08
Then multiply it to the amount in cost to get the tax - 20 x 0.08 = 1. 60
Now add the tax to the total - 20 + 1.6 = $21.60
To find the difference subtract Dave's with Mel's
$25. 80 - $21.60 = $4.20
MARKING BRAINLIEST PLZ HELP! You are given the following five lines:

Line 2: y= 1/2x + 1
Line 3: y= 2x + 2
Line 4: 6x - 3y = 6
Line 5: 4x + 2y = 4
Part A: Which two lines could be used to create a system of equations that has no solution? Explain your answer
Part B: Which two lines could be used to create a system of equations that has many solutions? Explain your answer
Part C: Which two lines could be used to create a system of equations that has one solution? Explain your answer
Part A:
lines y=-2x+9 and 4x+2y=4 can be used to create a system of equation that has no solution because none of the lines intercept on a graph.
Part B:
lines y=2x+2 and 6x-3y=6 can be used to create a system of equation that has infinitely many solutions because again none of the lines intercept on a graph
Part C:
The lines y=1/2x+1 and 4x+2y=4 can be used to create a system of equations with one solution because on a graph both lines intersect at one point.

C is clicked but I'm not sure if that is the answer I just clicked one. I need the answer to both.
Answer:
I believe that B is the correct answer!
Step-by-step explanation:
The (x+5) can cancel
Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.
Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)
Lastly the (x-5) on the top and bottom will cancel resulting in result B
I hope this helped!
Answer:
B(lol the one you chose randomly was right)
5, sorry I dunno the second number...
Step-by-step explanation:
(x+5)(x+5)(x-5)/ (x+5)^2(x-5)^2
(x+5)^2 gets canceled out
(x-5)/(x-5)^2
1/x-5
What is the equation of a line with slope 4 and passes through point (4,2)?
Answer:
y = 4x - 14

B. 1,266 mph
C. 432 mph
D. 423 mph
Answer:
423 mph
Step-by-step explanation:
To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.

Find the 64th term of the arithmetic sequence 2, -3, -8,
Answer:
[tex]a_{64} = -313[/tex]
Step-by-step explanation:[tex]a_{64} = 2 -135[/tex]
This is the Arithmetic Sequence Formula-> [tex]a_{n} = a_{1} + (n+1) d[/tex]
1) The d represents your difference of the equation. You can find it by finding a pattern between the three numbers given, which is -5
2) Now that we've found our difference, we can plug it into this lovely sequence we have [tex]a_{64} = a_{1} + (64-1) -5[/tex] (by the way, your n represents your term that you plug into the equation)
3) [tex]a_{64} = 2 + (64-1) -5[/tex] This also means that [tex]a_{1}[/tex] is our first term, which is 2
4) Simplify [tex]a_{64} = 2 + (63) -5[/tex] --> [tex]a_{64} = 2 +-315[/tex]
5) [tex]a_{64} = -313[/tex]
The formula is confusing at first, but it becomes easier once your learn the patterns!
