Answer: C)46 ft
Step-by-step explanation:
We know that the circumference of a circle can be calculated with this formula:
Where "r" is the radius of the circle.
Since John is putting a fence around his garden that is shaped like a half circle and a rectangle, then we can find how much fencing he needs by making this addition:
Where "l" is the lenght of the rectangle and "w" is the width of the rectangle.
Since we know that the radius of the circle is half its diameter, we can find "r". This is:
Then, substituting values (and using 
), we get:
Step-by-step explanation:
Unit rate = 24 ÷ 8 = 3 tires
Answer:
3) C
Step-by-step explanation:
The question is asking which pair is equal. Work through each problem to solve.
8(2r) and 10r
16r ≠ 10r
6r + 3 and 9r
6r + 3 ≠ 9r
9(3r - 4) and 27r - 36
27r - 36 = 27r - 36
r + r + r + r + r and r⁵
5r ≠ r⁵
Answer:
-256
Step-by-step explanation:
Put a negative next to 2^8 and you'll get your answer.
First, you have to round the .1, which would be .0. Next, you round 19.0, or just 19, to the nearest 10, which is 20. Therefore, 19.1 rounded to the nearest 10 is 20.
