Ac=20 bc=2x+12 ab=2x+8find x
Answer:
x = 0
Step-by-step explanation:
AB + BC = AC
therefore
2x+8 + 2x+ 12 = 20
combine like terms
4x+ 20 = 20
Subtraction property of equality
4x + 20 - 20 = 20 - 20
4x = 0
Division property of equality
4x/4 = 0/4
x=0

As per the given information in the question,
Original price of jeans = $80
Percentage discount on sale = 25%
Then, the discount of price on the jeans will be,
80 × 25/100 = $20
Then, the price of jeans after the discount will be,
$80 - $20 = $60

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibles?
( I need the answers, plus the steps please and thank youuu :)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the model:
s = 10│x - 4│+ 50
s represents the sound level in decibels and x represents the number of measures of music played
To find x at s = 80
The equation becomes /
80 = 10│x - 4│+ 50
Subtract 50 from both sides of the equation
80 - 50 = 10 |x - 4| + 50 - 50
30 = 10 | x - 4 |
Divide both sides by 10
30/10 = 10|x - 4| / 10
3 = |x - 4|
|x - 4| is an absolute value expression
±3 = |x - 4|
x = 3 + 4 = 7
x = - 3 + 4 = 1
Find three consecutive odd integers such that the sum of the smallest number and middle number is 27 less than 3 times the largest number
Answer:
x+(x+2) = 3(x+4) -27
Step-by-step explanation:
Let's look at all the parts.
Consecutive odd integers... that means that if x is the first one, then x+2 will be the next largest one, and x+4 will be the largest one. So if x is 5, x+2 is 7, and x+4 is 9.

ball is thrown 40 meters above ground. the height of the ball from the ground level after t seconds is defined by using the function h(t)=40t-5t^2. how long will the ball take to hit the ground
Answer:
The ball will take 8.90 seconds to hit the ground.
Step-by-step explanation:
The height of a ball after t seconds is given by:
[tex]h(t)=40t-5t^2[/tex]
Determine how long will the ball take to hit ground level. Since the gound is 40 meters below the throwing point:
[tex]40t-5t^2=-40[/tex]
Rearranging:
[tex]5t^2-40t-40=0[/tex]
Simplifying by 5:
[tex]t^2-8t-8=0[/tex]
Solving the quadratic equation with the formula:
[tex]\displaystyle t=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
With a=1, b=-8, c=-8
[tex]\displaystyle t=\frac{8\pm \sqrt{64+32}}{2}[/tex]
[tex]\displaystyle t=\frac{8\pm \sqrt{96}}{2}[/tex]
There are two solutions:
t=8.90 sec, t=-0.90 sec
Due to the nature of the problem, t cannot be negative, thus:
The ball will take 8.90 seconds to hit the ground.

What is the sine of an angle in a right angle triangle?The sine of an angle is the ratio of the height and the hypotenuse of the triangle.
Given, ∠C = 30°
AB = 16
Therefore, sin ∠C = (AB/AC)
Therefore, sin (30°) = 16/AC
⇒ (1/2) = 16/AC
⇒ AC = 2 × 16
⇒ AC = 32
