Answer:
Step-by-step explanation:
Yesterday, her rate was 8mph, her time was x hours.
Today, her rate was 13mph, her time was 13 - x hours.
So the total distance she biked on the two days is
d = 8x + 13(13 - x), or 169 - 5x
Total clay = πr²h = π x (4÷2)² x 6 = 12π in³
Clay ball = 4/3 x π x (1)³ = 4/3 π in³
Number of clay balls that can be made = 12π ÷ 4/3 π = 9

Answer:
A. √16
Step-by-step explanation:
A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.
From the options given, the only radical expression that has two perfect square is √16.
√16 consists of two perfect squares, which are 4 and 4.
4 can be expressed as 2 × 2.
Thus: √16 = √(2 × 2)(2 × 2).
Therefore, √16 consists of two perfect squares.
