The <u>probability</u> that a point <u>chosen at random</u> in the triangle is also in the blue square can be calculated using <u>geometrical definition of the probability</u>:

1. Find the total area of the triangle:

2. Find the desired area of the square:

Then the probability is

Answer: correct choice is B
Answer:
the answer is B. 99x + 84 ≥ 1,150
Step-by-step explanation:
the total price of the shirts was 84 dollars
the price of the watches was 99 each which is 99x
and it has to be less than 1150 or equal to that amount otherwise she would go over her savings

Answer:
C) 75 + 50x = 25 + 70x
Step-by-step explanation:
ABC Tech:
$50 an hour. So,for x hours= 50 * x = 50x
Service charge = 75 + 50x
Tech Squad:
$70 an hour. So,for x hours= 70 * x = 70x
Service charge = 25 + 70x
C) 75 + 50x = 25 + 70x
50x - 70x = 25 - 75
-20x = -50
x = -50/-20
x =5/2 = 2
