lan ran 24 laps in a charity run and then walked 0.2 kilometer to the presentation table the total; distance lan traveled was 29
QveST [7]

Answer:

Step-by-step explanation:

1.225km is equal to each laps

Step-by-step explanation:

Since Kristy total distance traveled = 29.6km

And Kristy ran 24 laps and later walk 0.2km. it simply implies that

Total distance traveled = distance covered running + distance covered walking

Since we know that

Total distance traveled = 29.6km

distance covered running = 24 laps

distance covered walking = 0.2km

Distance covered running in km = total distance traveled - distance covered walking

Distance covered running in km = 29.6km - 0.2km = 29.4km.

To now find the distance for each lap.

Since we have:

Distance covered running in km = 29.4km.

Distance covered running in lap = 24 laps

i.e

24 laps = 29.4km

1 lap = x

Use cross-multiple

24 laps * x = 29.4km × 1 lap

x = 29.4km / 24

x = 1.225km

Therefore

1.225km is equal to each laps.

Answer:

C) f(x) = |x|

Step-by-step explanation:

<em>Determine if Odd, Even, or Neither</em>

         f (x) = |x|

Find f (−x) by substituting −x for all occurrence of x in f (x). f(−x) = |−x|

Make −x positive.

        f(−x) = |x|

A function is even if  f(−x) = f(x).

Check if  f(−x) = f(x).

        |x| = |x|

Since |x| = |x|, the function is <em><u>even</u></em>.

Answer:

3. 35 adults and 420 children

4. The three numbers are 13, 52 and 16

Step-by-step explanation:

3. Let the number of adults be x.

Since there are 12 times more children than adults,

number of children= 12x

Total number of people= 12x +x

13x= 455

x= 455 ÷13

x= 35

12x= 35(12)

12x= 420

Therefore, there are 35 adults and 420 children at the play.

4. Let the first number be x.

Since the 2nd number is 4 times the first,

2nd number= 4x

Third number is 3 more than the first:

3rd number= x+3

sum of numbers= x +4x +x+3

6x +3= 81 (simplify)

6x= 81 -3 (bring constant to 1 side)

6x= 78 (simplify)

x= 78 ÷6

x= 13

Second number

= 4x

= 4(13) (subst. x=13)

= 52 (expand)

third number

= x +3

= 13 +3 (subst. x=13)

= 16
