Answer:
68 ft^2
Step-by-step explanation:
The shaded region is a square missing a triangle. Thus, the area of the shaded region = area of square - area of triangle
Thus, we get 8*9 - 1/2 * 2 * 4 = 72 - 4 = 68 square feet.
Answer:
P(RR) = 3/7 * 3/7 = 9/49
P(BB) = 4/7 * 4/7 = 16/49
We want to know P(RR) + P(BB)
P(RR) + P(BB) = 9/49 + 16/49 = 25/49
Step-by-step explanation:
20
Explanation:
20 + 4 = 24. Therefore 24-20=4
Answer:
1<X<=6
Step-by-step explanation:
seven less than six times her number is between negative one and twenty-nine (inclusive).
The above statement can be expressed mathematically thus;
Let the number be x
6x-7= (-1 ,29]
Hence 6x-7 = -1=>6x=6=>x=1 or
6x-7= 29=>6x=36=>x=6
Hence 1<X<=6
