Answer:
The answer is below
Step-by-step explanation:
The piece of plastic needed to cover the sand pit is the same as the area of the sand pit. Since the sand pit has a width of 2.56meters and a length of 8.75meters, it means that the sand pit is rectangular in shape. The area of the sand pit is given by the formula:
Area = length × width
Area = 2.56 meters × 8.75 meters
Area = 22.4 m²
The plastic needed to cover the sand pit needs to have an area of 22.4 m²
Answer:
1) +1,+2,+3,+6,-1,-2,-3,-6
2) f(2) = 0
3) (x+1)(x-2)(x-3)
4) x=-1, x=2, x=3
Step-by-step explanation:
For explanation, see the attached files
The intersection of two sets is the set composed by the elements that the two sets have in common.
So, we have
In this particular case, since Y is a subset of X, we have
In fact, all elements of Y are elements of X as well, so in particular they are common elements.

Answer:
15 dollars
Step-by-step explanation:
We can write a ratio to solve
6 cones 9 cones
------------ = --------------
10 dollars x dollars
Using cross products
6*x = 10 *9
6x = 90
Divide each side by 6
6x/6 = 90/6
x = 15
