A. Factor 28 + 7g  7(g <span>+ 4) 

add 
28 </span><span>+ 7g 

= 7 (g </span>+ 4)

B. (12r + 15) – 65 Remove parentheses
12r+15-65

= 12r - 50 

C. 24 – (8p – 12)

24 - (8p - 12) = -8p + 36 

24 - (8p - 12)  -(8p - 12) 8p + 12

= 24-8p+12

Simplify 24-8p+12 

Group like terms
-8p+12+24

Add the numbers  12+24=36

Answer is -8p+36

. Two bicyclists, Sarah and Emily, depart from the same location. Sarah heads N55°E at an average speed of 6 km/hr. Emily heads
Liula [17]

Answer:

The distance between them after 30 minutes is 6.5 km.

Step-by-step explanation:

Speed = \frac{distance}{time}

Sarah's speed = 6 km/hr = 1.6667 m/s

Emily's speed = 10 km/hr = 2.7778 m/s

The measure of angle between their bearings = 105^{o}

After 30 minutes (1800 seconds);

distance = speed x time

Sarah would have covered a distance = 1.6667 x 1800

                               = 3000 m

                               = 3 km

Emily would have covered a distance = 2.7778 x 1800

                               = 5000 m

                               = 5 km

The distance between them, a, can be determined by applying the cosine rule;

a^{2} = b^{2} + c^{2} - 2bcCos A

   = 5000^{2} + 3000^{2} -2(5000 x 3000) Cos 105

   = 5000^{2} + 3000^{2} -2(5000 x 3000) x (-0.2588)

   = 2.5 x 10^{7} + 9 x 10^{6} + 7764000

   = 41764000

a = \sqrt{41764000}

  = 6462.5073

a = 6462.5 m

The distance between them after 30 minutes is 6.5 km.

The first thing to do is the make the denominators of the fractions the same. 

5/10 of the pupils walked to school and 2/10 of the pupils came to school by bus. 
5/10 + 2/10 = 7/10. 
10/10 - 7/10 = 3/10.
