Svet_ta [14]
After a thorough research, there exists the same question that has the following choices.

A. 6.29 
<span>B. 12.57
</span><span>C. 18.86
</span><span>D. 25.13</span>

The correct answer is letter B 12. 57
First, we need to get the circumference
C = 2*pi*r
C = 12 pi
360/ 60+60 = 360/120 = 3
12 pi / 3 = 4 pi = 4 x 3.1415 = 12.57

The temperature in frostville was at 50*F at midnight,and it dropped at a constant rate for the next 10 hours.
bazaltina [42]

After 10 hours the temperature is shown on the graph as 30 degrees.

50 degrees - 30 degrees = 20 degrees.

The temperature dropped 20 degrees in 10 hours.

Divide the change by the time:

20 degrees / 10 hours = 2 degrees per hour.

Because the temperature dropped, the change would be negative.

The answer is D. -2 degrees per hour.

Multiply. 32√⋅28√⋅3√⋅6√ in simplest radical form, in the box.
PolarNik [594]

Answer:  48\sqrt{7}

Step-by-step explanation:

Given expression, \sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}

= √(4×8)×√(4×7)×√3×√(3×√2)

= √4×√8×√4×√7×√3×√3×√2 ( because √(m×n)=√m×√n)

=√4×√4×√8×√2×√7×√3×√3

=4×√(4×2)×√2×√7×3

=4×√4×√2×√2×√7×3

=4×2×2×√7×3

=48√7

Thus,\sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}=48\sqrt{7}
