Answer:
1. = 1 2. = 6 3. = 2.9 4. = 0.75 5. = 3.5 6. = 20.5
Step-by-step explanation:
⅘ + ⅕ = 1
3 ¾ + 2 ¼ = 6
25/10 + 4/10 = 2.9
10/8 - 4/8 = 0.75
$5 ¾ - $2 ¼ = 3.5
21.45 - 1 9/20 = 20.5

Answer:
A = 400 cm^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
80 = 4s
Divide each side by 4
80/4 = 4s/4
20 =s
We want to find the area of the square
A = s^2
A = 20^2
A = 400 cm^2
3x-6+1=-2x-5+5x
3x+2x-5x=6-1-5
10x=0
x=0

Answer:
d. 60k
Step-by-step explanation:
The sample mean is the midpoint between the lower and the upper limit of the confidence interval, that is, the sum of the lower and the upper limit divided by 2.
In this problem, we have that:
Lower limit: 50k
Upper limit: 70k
(50k + 70k)/2 = 60k
So the correct answer is:
d. 60k
