Ling is training for a marathon by jogging 6.3 kilometers every other day. How many meters does she jog every other day
Ling jogs 6300 meters every other day while training for a marathon. The conversion from kilometers to meters was done by multiplying the kilometer value (6.3) by 1000.
Explanation:To answer the question of how many meters Ling jogs every other day, we need to convert the distance from kilometers to meters. In the metric system, 1 kilometer is equivalent to 1000 meters. Therefore, if Ling jogs 6.3 kilometers every other day, we multiply 6.3 by 1000 to obtain the equivalent distance in meters.
Calculation: 6.3 kilometers * 1000 = 6300 meters.
So, Ling jogs 6300 meters every other day while training for the marathon.

Jared made 4 bird houses in 3 days. How many days will Jared work to make 20 bird houses
The number of days Jared will take to make 20 bird houses, when he can make 4 bird houses in 3 days, is 15 days.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
[tex]W=\dfrac{1}{n}[/tex]
Jared made 4 bird houses in 3 days. Thus, the number of bird houses made by Jared in 1 day is,
[tex]n=\dfrac{4}{3}[/tex]
Thus, the Jared made 4/3 housed in a single day. By this rate the total time required to Jared to make 20 bird housed is,
[tex]t=\dfrac{20}{\dfrac{4}{3}}\\t=\dfrac{60}{4}\\t=15\rm\;days[/tex]
Hence, the number of days Jared will take to make 20 bird houses, when he can make 4 bird houses in 3 days, is 15 days.

A) 174 minutes
B) 345 minutes
C) 1 hour 45 minutes
D) 2 hours 14 minutes
Answer:
Option(c)
Step-by-step explanation:
The race track on which the car is competing miles= 400 miles
A car travels with speed= 230 miles per hour
We have to find time taken for the car to finish
As we know,
Time taken to cover certain distance=[tex]\frac{Distance}{Time}[/tex]
Time taken to cover certain distance=[tex]\frac{400}{230}[/tex]
Time taken to cover certain distance=[tex]\frac{40}{23}[/tex]
Time taken to cover certain distance=1 hour 45 minutes

Each Day Marvin exercises for 48 minutes.How many days will it take him to exercise for 576 minutes?
By dividing the total desired exercise minutes (576) by the daily exercise duration (48 minutes), we find that Marvin will need 12 days to reach 576 minutes of exercise.
Explanation:To calculate how many days it will take Marvin to exercise for a total of 576 minutes, given that he exercises for 48 minutes each day, we divide the total minutes he wants to achieve by the number of minutes he exercises daily.
Total minutes desired: 576 minutes
Daily exercise duration: 48 minutes
To determine the number of days required, we perform the following calculation:
Divide 576 by 48.The result is the number of days Marvin needs to exercise to reach 576 minutes.576 minutes ÷ 48 minutes/day = 12 days
Therefore, it will take Marvin 12 days of exercising for 48 minutes each day to accumulate 576 minutes of exercise.

a wireless company offers two cell phone plans. Plan A charges 24.95 per month plus 0.10 per minute for calls. Plan B charges 19.95 per month plus 0.20 per minute. Use the questions to find when the two plans cost the same.
To find when the two plans cost the same, set up an equation equating the cost of Plan A and Plan B. Solve for the number of minutes used when the two plans cost the same.
Explanation:To find when the two plans cost the same, we need to set up an equation where the cost of Plan A is equal to the cost of Plan B. Let x be the number of minutes used. For Plan A, the cost is $24.95 + $0.10x. For Plan B, the cost is $19.95 + $0.20x. Setting these two expressions equal to each other, we get:
$24.95 + $0.10x = $19.95 + $0.20x
Now, we can solve for x:
$0.10x - $0.20x = $19.95 - $24.95
$-0.10x = -$5
x = -$5 / -$0.10
x = 50
Therefore, the two plans cost the same when 50 minutes are used.
