The answer is 2498.4km/h

The speed is 694m/s =  \frac{694m}{1s}

1 m = 0.001 km          ⇒        694 m = 694 * 0.001 km = 0.694 km
1 h = 60 min = 60 * 60 s = 3600 s 

Therefore:
\frac{694m}{1s}= \frac{3600*0.694km}{3600s} = \frac{2498.4km}{1h} =2498.4km/h

Answer:

y=3x+19.

Step-by-step explanation:

1) according to the condition the line 't' is parallel to the line 's', it means, the equation of the line 't' is: y=3x+C, where C - unknown number.

2) in order to calculate the 'C', it need to substitute the given coordinates into the equation of the line 't', then:

-2=3*(-7)+C, ⇒ C=19.

3) if C=19 and the equation of the line 't' was y=3x+C, then it is possible to make up the full required equation:

y=3x+19.

Zinaida [17]

Answer:

2967 yes votes

Step-by-step explanation:

Welcome to Brainly!

One way of doing this problem follows:

Find the ratio, r, mentioned in the problem statement.  To do this,

write the equation 3r + 5r = 7912 and solve this for r:

8r = 7912, so that r = 989.

Then the number of yes votes was 3(989), or 2967, and the number of no votes was 5(989), or 4947.

check:  Does the ratio 2967/4947 equal 3/5?  yes.

There were 2967 yes votes.
