Use a calculator to find the decimal equivalents.
Then comparing the numbers is easy.
Answer:
93 pieces
Step-by-step explanation:
To cover his backyard with sod, he needs to cover the area of the backyard.
His backyard is a rectangle, and area of a rectangle is given as:
Where,
is the length, and
is the width
So, the area of Jim's backyard is square yards.
The area of each sods are solved using the area of the rectangle formula. So we have square yards as the area of each sod.
To find HOW MANY of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:
Since, fractional sods can't be bought, Jim has to buy 93 sods to cover his backyard.
Then the original price was $42
Because it is half off we multiply 21 by 2 and get 42.
This is a function since it passes the vertical line test. It is impossible to draw a single vertical line to have it pass through more than one point on the curve.
The domain is the set of numbers x such that x is between -3 and +3 excluding those endpoints. In other words, the domain is -3 < x < 3. We never actually get to either endpoint because of the vertical asymptotes.
The range is the set of all real numbers. It is possible to get any output we want depending on the specific input.
