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.

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.

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
Answers
Answer:
350 girls
Step-by-step explanation:
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.

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 width of a rectangle is three more than twice the length. The perimeter is 96 inches. Find the length and the width.
Answers
Answer:
The length of the rectangle is 15 inches and the width is 33 inches
Step-by-step explanation:
The dimensions for the rectangle are as follows:
L=L and W=2L+3
The equation for perimeter of a rectangle is:
P=2l+2w
To Solve:
1. Plug values into perimeter equation
96=2(L)+2(2L+3)
2. Simplify the equation above.
96=2L+4L+6
3. Combine like terms:
96=6L+6
4. Solve for L by subtracting 6 from both sides:
90=6L
5. Solve for L by dividing both sides by 6:
15=L.
6. Plug 15 into the equation for the width:
2(15)+3=w
30+3=w.

Answers
Answer:4%
Step-by-step explanation:
From the question, we are informed that a jigsaw puzzle is priced 17.00 but cost 17.68 at the register. This means that the sales tax is (17.68 - 17.00) = 0.68.
Therefore, the sales tax rate will be calculated as:
= (0.68 / 17.00) × 100
= 4%
The sales tax rate is 4%
