Answer:
t = 5
Step-by-step explanation:
Given
t + 2 = 7 ( isolate t by subtracting 2 from both sides )
t = 7 - 2 = 5
7 + 5 = 12 so is an even number that the ticket the choose
Answer is C => 4(80+20)-12 => 4(100)-12 =>400-12 => 388

Answer:
D. (25π - 50) sq m
Step-by-step explanation:
Since ABCD is a square with the area of 100, we know that the dimensions are 10 by 10. With that, we can find that triangle ABC = 50 sq m because of (h*l)/2. Since A is the center of the circle that contains arc BD, we know that 10 is the radius of the quarter-circle ABC. Using (πr^2)/4 to get the area of the quarter-circle, we get that the quarter-circle ABC = 25π sq m. But the original triangle ABC in the quarter-circle is not shaded. Therefore, we subtract 50 from 25π, which leads to (25π - 50) sq m.
I hope this helped! :D
