kristy ran 24 laps in chairity run and then walked 0.2 kilometer to the presentation table. The total distance Kristy traveled was 29.6 kilometers. What was the distance of each lap? Explain how you solved the problem.

Answers

Answer:

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.

totaldistanceof24laps

29.6km - 0.2km

=29.4km

totaldistanceofeachlap

24 laps = 29.4km

1 lap = ?

Usecross-multiple

24 laps × X = 29.4km × 1 lap

X = 29.4km / 24

X = 1.225km

Answer

1.225km

8 kg of potatoes and 5 kg of carrots cost $28 whereas 2 kg of potatoes and 3 kg of arrot cost $11.20.what is the cost of 1 kg of each item

Answers

1 kg of potatoes costs x, 1 kg of carrots costs y.

8x+5y=28 | :(-4)
2x+3y=11,2

-2x-1,25y=-7
2x+3y=11,2

3y-1,25y=11,2-7
1,75y=4,2
y=2,4

1 kg of carrots costs $2,4.

1 kg of potatoes costs:
2x+3*2,4=11,2
2x+7,2=11,2
2x=11,2-7,2
2x=4
x=2
1 kg of potatoes costs $2

What is 4/5+11/12= ?

Answers

Answer:

4/5+11/12= 1 43/60

Ben's Bicycle Helmets makes bicycle helmets at a cost of 3000 + 12x dollars per month toproduce x helmets. They sell the helmets for $21 each.
1. Determine the cost to produce 500 helmets.

Answers

Answer:

Cost to produce 500 helmets will be $9000.

Step-by-step explanation:

Expression that represents the cost of the bicycle helmets is given as

C = 3000 + 12x

where x = number of helmets produced.

1. Cost of production of 500 helmets can be calculated by putting x = 500 in the expression.

C = 3000 + 12×500

= 3000 + 6000

= $9000

Therefore, cost to produce 500 helmets will be $9000.

Answer:

$9000

Step-by-step explanation:

3000+12x

x = 500

3000 + (12*500)

3000+6000

$9000
