<u>Answer:</u>

The hand moved \bf \frac{3}{4} of a complete turn.

<u>Step-by-step explanation:</u>

The hand moved from 3 to 12, that is, it moved:

12 - 3 = 9 hours

In a clock, 12 hours represent a complete turn.

∴ Using the unitary method:

12 hours    ⇒     1 turn

1 hour        ⇒     \frac{1}{12} turns

9 hours     ⇒     \frac{1}{12}  × 9 = \frac{9}{12}

                                     = \bf \frac{3}{4} turns    (simplified)

∴ The hand moved \bf \frac{3}{4} of a complete turn.

The answer is  \boxed{\frac{3}{4}}.

To find the fraction of a complete turn it moved in this case, take the ratio between hours covered between 3 and 12, and the hours covered in a complete turn.

  • Hours covered between 3 and 12 : 12 - 3 = 9
  • Hours covered in a complete turn = 12
  • Fraction of a complete turn it moved : 9/12 = 3/4

The other grid will have exactly 47 of the 100 little squares shaded. That's exactly .47 of the whole grid.

What is the angle measure of angle ABC?​
Aliun [14]

Answer:

92°

Step-by-step explanation:

First, find the value of x.

3x + 23 = 4x (corresponding angles are congruent)

Subtract 3x from each side

23 = 4x - 3x

23 = x

x = 23

Angle ABC = 4x

Plug in the value of x

Angle ABC = 4(23)

Angle ABC = 92°
