The distance around the outside of cedar parks is 0.8 miles joanie ran 0.25 of the distance during her lunch break how far did she run

Answers

Answer:

If the total distance is 0.8km we need to multiply that amount by the proportion that she ran, which was 0.25 (one quarter or 25%). So 0.8km x 0.25 = 0.2km Looking another way, the word 'of' often means the same as 'multiply', so 0.25 of 0.8km = 0.25 x 0.8km = 0.2km Joanie ran a total of 0.2 km during her lunch break.

Taylor and Anya live 63 miles apart. Sometimes on a Saturday, they ride their bikes toward each other's houses and meet somewhere in between. Taylor is a very consistent rider - she finds that her speed is always very close to 12.5 miles per hour. Anya rides more slowly than Taylor, but she is working out and so she is becoming a faster rider as the weeks go by. On a Saturday in July, the two friends set out on their bikes at 8 am. Taylor rides at 12.5 miles per hour, and Anya rides at 5.5 miles per hour. After one hour, how far apart are they?

tHE SPEED OF SOUND IN AIR IS 1100 FEET PER SECOND. THE SPEED OF SOUND IN STEEL IS 1500 FEET PER SECOND. ROBIN ONE EAR PRESSED AGAINST THE RAILROAD TRACK, HEARS A SOUND THROUGH THE RAIL SIX SECONDS BEFORE HEARING THE SAME SOUND THROUGH THE AIR. TO THE NEAREST FOOT HOW FAR AWAY IS THE SOURCE OF THAT SOUND

Answers

To the nearest foot the distance of source of that sound is 24,750 feet.

Given that;

Speed of sound in air = 1100 feet per second

Speed of sound in steel = 1500 feet per second

Time difference = 6 seconds

We have to find the nearest foot for the distance of source of that sound.

What is relation between distance, speed and time?

The relation between distance, speed and time is;

Speed = Distance/Time

We have;

Time difference = 6 seconds

Let the distance = x feet.

For the air;

Distance = x feet

Speed of sound in air = 1100 feet per second

Then, Time = Distance/speed = x / 1100

And, For steel ;

Distance = x feet

Speed of sound in steel = 1500 feet per second

Hence, Time = Distance/speed = x/1500

Since, Time difference = 6 seconds

Hence, The equation become;

x / 1100 - x/1500 = 6

(1500x - 1100x)/1100*1500 = 6

400x = 6 * 1100 * 1500

x = 24,750 feet.

Hence, To the nearest foot the distance of source of that sound is 24,750 feet.

Jade’s weekly paycheck is $306.25. She makes $8.75 per hour. Divide to find the number of hours per week Jade works.

Answers

Answer:

35 hours a week

Step-by-step explanation:

306.25 / 8.75

Answer:

Jade works for a total of 35 hours per week.

Step-by-step explanation:

Since Jade's weekly paycheck is $306.35, and she makes $8.75 per hour, we need to divide the weekly amount by the hourly amount to find the amount of weeks that Jade works.

$306.25 ÷ $8.75 = 35

Therefore, Jade works for a total of 35 hours per week.
