A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute. The minute hand rotates through 360° in 60 minutes or 6° per minute.

Answer:

See below in bold.

Step-by-step explanation:

1.  x/8 = 15/24

Cross multiplying:

24x = 8*15

x = (8*15)/24

x = 5.

2.   5/6 = 35/x

5x = 6*35

5x = 210

x = 210/5

x = 42.

3.<em>  </em>18/42

Divide top and bottom by 6:

18 / 6 / 42/6

= 3/7.

4.  15/75

Divide top and bottom by 15:

= 1/5.

katrin [286]

Step-by-step explanation:

the area is

length × width

increasing the length by 30% means multiplying the original length by 1.3.

increasing the width by 10% means multiplying the original width by 1.1.

so, the new area is (by using the old length and width)

length × 1.3 × width × 1.1 = length × width × 1.3×1.1 =

= old area × 1.3 × 1.1 = old area × 1.43

so, the area increases by 43%.
