At a concert 20 percent of the audience member were teenagers. If the number of teenagers at the concert was 360,what was the total number of audience members?
Answer: 1,800
Step-by-step explanation: At a concert, 20% of the audience members were teenagers. If the number of teenagers at the concert was 360, what was the total number of audience members? x = ? If you divide 360 by 20% it will give you 1,800 audience members.
I need to find out the value of x in this triangle because I don’t understand the formula
Answer:
x = 55 degrees
Step-by-step explanation:
Firstly, as told by the question, we know that this is an isosceles triangle because AB and BC are the same length. This means that angle A and C will be equal. Next, we also know that all angles in a triangle will always add to 180 degrees. Therefore we can write an equation adding up all the angles to solve for x:
Angle A can be represented as 'x'
Angle B is represented 'x+15'
And Angle C can also be represented 'x' as it is equal to angle A
So our formula will be in this format: A+B+C=180
x+x+(x+15)=180
To solve this equation we first take out the brackets and combine like terms:
3x+15=180
Now we need to isolate 'x' so we will end up with a numerical value for it, which we do by subtracting 15 from both sides and then dividing both sides by 3:
3x+15-15=180-15
3x=165
3x/3=165/3
This gives us:
x=55
Hope this helped!
Solve for x. (1 point) −3x + 2b > 8 x < the quantity negative 2 times b plus 8 all over negative 3 x > the quantity negative 2 times b plus 8 all over negative 3 x < the quantity 2 times b minus 8 all over negative 3 x > the quantity negative 2 times b minus 8 all over 3
Given:
[tex]-3x+2b>8[/tex]
To find:
The value of x.
Solution:
We have,
[tex]-3x+2b>8[/tex]
To find the value of x, we need to isolate x on one side.
Subtract 2b from both sides.
[tex]-3x>8-2b[/tex]
Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.
[tex]\dfrac{-3x}{-3}<\dfrac{8-2b}{-3}[/tex]
[tex]x<\dfrac{-2b+8}{-3}[/tex]
The required inequality for x is [tex]x<\dfrac{-2b+8}{-3}[/tex].
Therefore, the correct option is A.
What is the equation of the line that passes through the point (6, -1) and has a
slope of 1?
Answer:
y = x – 7
Step-by-step explanation:
Answer:
y= x -7
Step-by-step explanation:
The equation of a line can be written in the form of y=mx+c (also known as slope-intercept form), where m is the gradient and c is the y-intercept.
Given that the slope is 1, m= 1.
Substitute the value of m into the equation:
y= 1x +c
y= x +c
To find the value of c, substitute a pair of coordinates.
When x= 6, y= -1,
-1= 6 +c
c= -1 -6 (-6 on both sides)
c= -7
Thus, the equation of the line is y= x -7.
How exactly would I find a slope to a graph?
Answer:
If the graph is rising from left to right, like climbing a hill, the slope is positive (on a graph, you could count up y units divided by right x units). If it is going down from left to right (like sliding down a hill), the slope is negative (on a graph you have to count down y units and right x units).
Step-by-step explanation:
Answer:
Most people would do it by subtracting your 2 y points (any points) and dividing the by the two x points. Basically, y2-y1/x2-x1. Hoped I could help you on this one.

the sum of two consecutive integers is 62. what are the two consecutive integers?
Answer: So our two integers are 17 and 45.
Step-by-step explanation:
The two integers are 17 and 45, See how we got it. X+Y=62. Substitute our first expression here for y, we have X+2X+11 =62.
Given that,
the two numbers are consecutive(also odd)
The two numbers are
x and x + 2
Sum of the numbers = 62
x + (x + 2) = 62
x + x + 2 = 62
2x = 62 - 2
2x = 60
x = 60/2
x = 30
Therefore, the two numbers are x = 30 and x + 1 = 32

A new vehicle is worth $2500. If it depreciates records in value 12% per year, after 6 years what will it be worth
Answer:
Step-by-step explanation:
2500 - 12%
12% of 2500 = 300
2500 - 300 = 2200
12% of 2200 = 264
2200-264=1936

What is the velocity of an object with a kinetic energy of 100 , 000 J 100,000 J100, comma, 000, start text, space, J, end text and a mass of 800 kg 800 kg800, start text, space, k, g, end text? Round your answer, if necessary, to the nearest hundredth.
Given:
Kinetic energy (KE)= 100,000 J
Mass (m)= 800 kg
To find:
The velocity of the object to the nearest hundredth.
Solution:
We know that,
[tex]KE=\dfrac{1}{2}mv^2[/tex]
where, KE is kinetic energy (in J), m is mass (in kg) and v is velocity (in m/s).
Put KE=100000 and m=800 in the above formula.
[tex]100000=\dfrac{1}{2}(800)v^2[/tex]
[tex]100000=400v^2[/tex]
Divide both sides by 400.
[tex]\dfrac{100000}{400}=v^2[/tex]
[tex]250=v^2[/tex]
Taking square root on both sides.
[tex]\sqrt{250}=v[/tex]
[tex]v=15.8113883[/tex]
[tex]v\approx 15.81[/tex]
Therefore, the velocity of the object is 15.81 m/s.
