Find the area of all the sides:
10 x 9 = 90
9 x 8 = 72
1/2 x 6 x 8 = 24
1/2 x 6 x 8 = 24
6 x 9 = 54
Add them up:
90 + 72 + 24 + 24 + 54 = 264 square metres
Answer:
1/38
Step-by-step explanation:
Given :
Probability = required outcome / Total possible outcomes
Total possible outcomes = total Numbe rod sections = 38
Required outcome = number of 1's on the entire section = 1
Hence, the probability of spinning a one equals :
P(spinning a 1) = 1 / 38
Answer:
x = ±i sqrt(3/2)
Step-by-step explanation:
2x^2+7 = 4
Subtract 7 from each side
2x^2+7-7 = 4-7
2x^2 = -3
Divide by 2 on each side
2x^2/2 = -3/2
x^2 = -3/2
There is no real solution, only imaginary solutions
Taking the square root of each side
sqrt(x^2) = sqrt(-3/2)
x = ±i sqrt(3/2)
Answer:
The solution is (-∞, 0.125) ∪ (0.18,∞)
Step-by-step explanation:
we have
This is a compound inequality
or 
Remember that
so
-----> the solution is the interval (0.18,∞)
----> the solution is the interval (-∞, 0.125)
The solution of the compound inequality is
(-∞, 0.125) ∪ (0.18,∞)
Answer:
- 2 ≤ n < 8
Step-by-step explanation:
The closed circle at - 2 indicates that n can equal - 2
The open circle at 8 indicates that n cannot equal 8
Otherwise n can be all value between - 2 and 8 including - 2, thus
- 2 ≤ n < 8
