Answer:
a) The amount of edging needed = 7.54 meters
b) Cost to edge the garden = $32.80
Step-by-step explanation:
a)
the amount of edging needed is basically the circumference (perimeter) of the circle. It has the formula:
Where
C is the circumference
r is the radius
Given, diameter = 2.4, radius is HALF of it, so
r = 2.4/2 = 1.2
Now, finding circumference:
The amount of edging needed = 7.54 meters
b)
$4.35 is needed to edge 1 meter, since we need 7.54 meters, we find the total cost by multiplying 4.35 with 7.54, so we have:
4.35*7.54 = $32.80
Cost to edge the garden = $32.80
You’re answer here is the third one
Answer:
Yes you did good job
Step-by-step explanation:
x+3/x-1 ; x=-2
-2+3/-2-1
-1/3
So basically you substitute x by -2 and solve from there. Your answer is -1/3.

Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
A be the event that the person has 2 siblings.
B be the event that the person does not have a pet.
Since they are not independent events.
Because if P(A|B) = 0.18
in case if they are independent events then, P(A|B) = P(A).
But here P(A) = 0.4
So, they are not independent events.
Hence, Fourth option is correct.
