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

Is the following number irrational?
-8.7
Answer:
No.
Step-by-step explanation:
Rational numbers are any of the following:
Integers (positive whole numbers, negative whole numbers, or zero).Fractions e.g. 3/4Terminating (with an end) or repeating decimals e.g. 0.2 or 0.333333... or 0.343434...Irrational numbers are thus defined as:
Non-terminating (unending), non-repeating decimal numbers. e.g. π, surds ( [tex]\sqrt{2}[/tex] ).This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.

Two friends rent an apartment together.
They agree that one person will
рау 1.5
times what the other person pays. If the rent
is $850, how much will each friend pay?
Answer:
Friend A pays $340 and friend B pays $510
Step-by-step explanation:
Let's call
x: payment of friend A
1.5x: payment of friend B
The sum of both payments must total $850, thus:
x + 1.5x = 850
Simplifying:
2.5x=850
x = 340
Now for friend B:
1.5x=1.5*340=510
Friend A pays $340 and friend B pays $510

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)
Answer:
y = -2/3x + 8/3aStep-by-step explanation:
Given points
(a, 2a) and (-5a, 6a)Slope-intercept form
y = mx + bSlope of the line is
m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3The y-intercept is:
2a = -2/3*a + bb = 2a + 2/3ab= 8/3aSo the line is:
y = -2/3x + 8/3aAnswer:
y = -2/3 - 8/3a
Step-by-step explanation:
Find the slope using [ y2-y1/x2-x1 ]
6a-2a/-5a-a
4a/-6a
-2/3
Find the y-intercept.
y = mx + b
y = -2/3x + b
2a = -2/3(a) + b
-8/3a = b
y = -2/3 - 8/3a

Daniel kicks a soccer ball and the trajectory is modeled by f(t) =− 16t^2+ 32t .
a. What would the value be of f(1)?
b. If it takes 2 seconds for the ball to hit the ground, what would a reasonable domain be for this function?
Answer:
f(1) = 16
Domain: 0 ≤ t ≤ 2
Step-by-step explanation:
Given
f(t) = -16t²+ 32t
Solving (a): f(1)
Substitute 1 for t in f(t)
f(t) =− 16t²+ 32t .
f(1) =− 16 * (1)²+ 32 * 1
f(1) = -16 * 1 + 32
f(1) = -16 + 32
f(1) = 16
Solving (b): The domain
The implication of the given parameter in (b) is that t ≤ 2.
Since t represents time, t can't be negative.
Hence, a reasonable domain is
0 ≤ t ≤ 2

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

Step-by-step explanation:
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
