Answer:

See below.

Step-by-step explanation:

This is focusing on the order of operations.

PEMDAS = Parenthesis, exponents, multiplication, division, addition, subtraction.

40 ÷ [(18 - 9) - (13 - 12)]

40 ÷ [9 - 1]

40 ÷ 8

5

[(13 - 9) · 3] + [(14 - 8) · 2]

[4 · 3] + [6 · 2]

12 + 12

24

Can somebody please help me?

 <span>for the first part, realize that the hour and minute hands are moving at different rates; in one hour, the minute hands moves all the way around the face of the clock, and thus moves a total of 360 degrees or 2 pi radians; the hour hand moves only 1/12 away around the clock, so covers only 30 degrees or Pi/6 radians. 

Now, the LINEAR distance traveled by the tip of each hand is also determined by the length of the hand. In the case of the minute hand, it sweeps out a circle of radius 10 cm, so traces out a circle of radius 10 cm. Since the circumference of a circle is 2*pi*r, the minute hand (remember it made one complete cycle) covers a distance of 2*pi*10cm=20 Pi cm 

The hour hand covers only 1/12 a circle, but that circle is only 6 cm in radius, so the distance traveled by the tip of the minute hand is: 

1/12 *[2 *pi*r]=1/12*[12*pi]=pi 

so the difference is 19pi 

for the last part, you should draw a diagram of the two hands, the minute hand is 10 cm in length, the hour hand is 6 cm in length, and they are 30 degrees apart...from that drawing, see if you can figure out the remaining leg of the triangle you can form from them 

good luck</span><span>
