$120
Step-by-step explanation:
<u><em>The complete question is</em></u>
Shelley designed the patio below, in which one side of the patio is a wall of the house. The length of each side of a square on the grid represents 3 meters.
Shelley plans to enclose the patio with fencing. If fencing costs $5 per meter, how much will it cost to enclose the patio?
$40
$60
$120
$180
<u><em>The picture in the attached figure</em></u>
Find the perimeter of the patio in units (without the wall of the house)
Multiply the perimeter by the cost of the fencing per meter
Answer:
each person gets $5
Step-by-step explanation:
(21-6)/3
21-6=15
15/3=5
Answer:
C) 12/20
Step-by-step explanation:
Between 1 and 20, 10 numbers are even, 4 numbers are perfect squares (1, 4, 9, and 16), and 2 numbers are both even and perfect squares (4 and 16).
So the probability is:
(10 + 4 − 2) / 20 = 12/20.
We can not evaluate it with real numbers, because there is no real number that multiplies itself twice and gives -25.
The answer is an imaginary number.
√-25 = 5i where i = √-1
So it can only be computed using imaginary numbers.
We will use u-substitution:
u = sin x, du = cos x dx
