PLEASE HELP!!!
Ken Runfast is the star of the cross-country team. During a recent morning run, Ken averaged a speed of 5.8 m/s for 12.9 minutes. Ken then averaged a speed of 6.10 m/s for 7.1 minutes. Determine the total distance which Ken ran during his 20 minute jog.

Answers

Answer 1

Answer:

7087.8m or 7.09km

Step-by-step explanation:

formula used:

distance = speed * time

total distance = distance1 + distance2

let d1 be distance1, d2 be distance2, s1 be speed1, s2 be speed2, t1 be time1, and t2 e time2:

s1 = 5.8m/s, t1 = 12.9 min or 774 sec, s2 = 6.10m/s, t1 = 7.1 min or 426 second

d1 = s1 * t1

   = 5.8 m/s * 774 s

   = 4489.2 m

d2 = s2 * t2

   = 6.10 m/s * 426 s

   = 2598.6 m

total distance = d1 + d2

                       = 4489.2m + 2598.6m

                       = 7087.8 meter or 7.09 kilometer

Find five numbers that have a mean of 10 and a median of 12.

Answers

Answer:

There are infinitely many solutions. Start with five data, in size order: a < b < c < d < e. Then c=11, the median. To get the mode of 12, we must have d=e=12. Thus far, we have (a+b+11+24)/5 = 10 the mean. But now we have run out of requirements, and we still have two unknowns. They satisfy a+b+35 = 50. Thus, pick any two values a not equal to b that add to 15 and are both less than 11.

The full set of solutions are points (a,b) run along a line joining the points (4,11) and (11,4) on graph paper, except (7.5, 7.5) and the endpoints. That would make competing modes. Try a=5.6 and b = 9.4 for instance!

Answers

Answer:

Step-by-step explanation:

First, solve four your last bracket, 2 squared is 4 and minus 5 is -1 times 21 is -21. Yet because the outer symbol is a negative, all signs change-making 21 positive. Solve 4*-6, and you get -24. This leaves you with [2-24-4+21] that gives you -5. Yet, because the outer sympol is a negative, 5 becomes positive. This leaves you with 1.

Answer:

71

Step-by-step explanation:

− 4 − [2 + 4(− 6) − 4 − (2²- 5×21)]

− 4 − [2 + 4(− 6) − 4 − (4 - 5×21)]

− 4 − [2 + (-24) − 4 − (4 - 105)]

159 students.

Since all you need to do is multiply 120×1.3/4=39, then you add 120, as we are told that there are 120 boys. Basically, there are 39 girls and 120 boys, since by multiplying 20×1.3/4 equals 39, so 39 girls, and 120 boys. Now add them all together, 120+39=159.

The letters a and b represent nonzero constants solve
ax-b=12.5 for x

Answers

Answer:

x=(12.5+b)/a

Step-by-step explanation:

ax-b=12.5

ax=12.5+b

x=(12.5+b)/a

The solution for the equation ax - b = 12.5 for x is:

x = (12.5 + b) / a

We have,

To solve the equation ax - b = 12.5 for x, follow these steps:

- Add b to both sides of the equation:

ax - b + b = 12.5 + b

This simplifies to:

ax = 12.5 + b

- Divide both sides of the equation by "a":

(ax) / a = (12.5 + b) / a

Simplify:

x = (12.5 + b) / a

Thus,

The solution for the equation ax - b = 12.5 for x is:

x = (12.5 + b) / a
