Answer:
The correct option is (A).
Step-by-step explanation:
The expression Carey is solving is:

Simplify the expression as follows:


So, in Carey's calculation the third step is incorrect.
Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.
Thus, the correct option is (A).
Answer:
(-3,-1)
Step-by-step explanation:
You can graph both of the points on desmos, and then look at the slope from p1 to the midpoint. so you can get the slope, and use it to get the p2. the slope is -4/6. So you get that answer.
Answer:
The answer is...... NO
Step-by-step explanation:
Step 1: Plug in your values in the x and y cordinates.
2(5) + 8 > 18
Step 2: Solve
Then you multiply 2 and 5 and get 10.
SO then your equation should look like this:
10 + 8 > 18
The answer to the question is no because in order for this to work it would need to be the greater than or equal to sign, which looks like this ≥.
Hope this helps and have a great day! :)
Just divide 121 by 11 to get your answer.
Diameter of a semi circular garden = 18 feet
Radius of the garden :



Thus, the radius of the semi circular fence = 9 feet
We know that :

Which means, the circumference of Mary's semi circular garden :

(pi value = 3.14)


Thus, the circumference of fence needed for the semi circular garden = 28.26 feet
28.26 can be rounded off to 28.30 and 28.30 is the same as 28.3
Thus, Mary's reasoning is correct.
Therefore, Mary's reasoning is correct which means she needs 28.3 feet of fence to surround her garden.
