-8-11 = -19
The vertical lines are for the absolute value, which is always a positive number.
The answer would become 19.
The answer is D.
Hi,
-8 - 11 = -19
The 2 lines at the beginning and the end equal the positive value of the number.
-19 ------> 19
Answer:
19
Mike saves $36 by buying the shirts at a discounted price.
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Given the offer,
By 1 at regular price ($45) and get 40% off on two shirt
40 % of 45 ⇒ 0.40 × 45 = $18
So shirt price = 45 - 18 = $27/each
Since 2 shirt buy at this price = 2 × 27 = $54
Money saved = 2×45 - 54 = $36
Hence "Mike saves $36 by buying the shirts at a discounted price".

Answer:
54
Step-by-step explanation:
p + 2q = 3,
p - 2q = 3
Answer:
p=3 q=0
Step-by-step explanation:
p+2q=3
p-2q=3
p+2q=3
p=3-2q---------eqn i
p-2q=3
3-2q-2q=3
3-4q=3
-4q=3-3
q=0÷-4
q=0
putting the value of q in equation i
p=3-2q
=3-2×0
=3
Answer:
p=3
q=0
Step-by-step explanation:
Adding both the equation
p+2q=3
+ p-2q=3
------------
2p=6
p=3
putting value of p in any of the above equation we will get the value of q.
3+2q=3
2q=0
q=0

Calculate the size of the serving angle A.
Give your answer correct to the nearest degree.

The person serving stands at point A and tries to serve the ball somewhere between
point C and B on the edge of the opponent's side.

Answer:
To calculate the size of the serving angle A in the diagram of the volleyball court, you can use trigonometry.
You have the following information:
The distance from point A to point C is 9 meters.
The distance from point A to point B is 31 meters.
To find angle A, you can use the inverse tangent (arctan) function:

Rounded to the nearest degree, the size of the serving angle A is approximately 73 degrees.
Step-by-step explanation:
Sure, I'll explain it in a simpler way:
Imagine you're standing at point A on the volleyball court, and you want to serve the ball towards point C or point B. Point C is 9 meters away, and point B is 31 meters away from you.
To find out how wide the angle is between where you stand (point A) and where you want to serve the ball (between points C and B), we can use a special math trick. It's like saying, "How much do I need to aim to the left or right?"
We use something called "arctan" to figure it out. When we do the math, we find that the angle A is about 73 degrees. So, you need to aim your serve at about a 73-degree angle to get the ball between points C and B on the other side of the court.
