Answer:

Step-by-step explanation:

This is the information we know :

A. a = 4

B. b = 15

C. c = 16

a + c

The a and c represent variables that must be substituted by their value, since we know their initial value, we substitute :

a + c when a = 4 and c = 16

4 + 16

At the first meeting of the Tennis Club, the 7 members decided to have a tournament in which every player will play a match agai

mariarad [96]

Answer:

21 matches

Step-by-step explanation:

This is a combination problem where we have to select two member out of 7 members

So we want calculation of 7C2

7C2 = 7!/[(2!)(7-2)!]

(7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]

(7*6)/2 ~ Note everything that easily cancels here!

42/2

21 matches

The flash of lightning travels at the speed of light, which is about 186,000 miles per second. The sound of lightning (thunder)

4vir4ik [10]

Answer:

A. Distance of the lightning after 4 seconds = 744,000 miles

B. Distance of the lightning after n seconds = 186,000 * n

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of lightning = 186,000 miles per second

Speed of sound = 750 miles per hour

2. A. If you see a flash of lightning, then hear the thunder 4 seconds later, how far away is the lightning?

Distance of the lightning after 4 seconds = 186,000 * 4

Distance of the lightning after 4 seconds = 744,000 miles

B. Now let’s generalize that result. Suppose it takes n seconds to hear the thunder after a flash of lightning. How far away is the lightning, in terms of n?

Distance of the lightning after n seconds = 186,000 * n
