Answer:
16.7
Step-by-step explanation:
We can use the Pythagorean Theorem [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]. So we write the equation below and solve for b.
[tex]9^{2}[/tex] + [tex]b^{2}[/tex] = [tex]19^{2}[/tex]
81 + [tex]b^{2}[/tex] = 361
[tex]b^{2}[/tex] = 280
b = 16.7
Answer:
h²=p²+b²
(19)²-(9)²=b²
361-81= b²
b²=280
b= √280
:. b=+-16.733

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
35
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.

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 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.
