One of the largest swimming pools in the world is in Garden City, Kansas. It is rectangular and
measures 67 meters by 100 meters. If you swim diagonally across the pool, how many meters would
you swim? Round your answer to the nearest whole meter
Answers
Answer:

Answer:
120 meters (approx)
Step-by-step explanation:
Think of the rectangle like two triangles;
if we find the hypotenuse of one, then we know the length of the rectangle across
Remember the Pythagorean theorem:
a^2 + b^2 = c^2
where a and b are the sides of the triangle
so then substitute in the known values:
a = 100
b = 67
now solve
100^2 + 67^2 = c^2
14489 = c^2
sqrt(14489) = c
120.37 = approx c

The bill at a restaurant came to $136.40.The customer decided to leave a 15% tip.What was the total bill including tip.
Answers
Answer:
$156.86
Step-by-step explanation:
To calculate tip, you need to multiply the total bill by the percent tip you are going to leave. In this case the bill is $136.40, and the customer is going to leave a 15% tip. So, you would want to move the decimal place over to the left by 1, which you should get 13.64 as your number. Then divide it in half, which should give you 6.82. Now add 13.64 and 6.82 with the original bill price. If you don't add the 13.64 you would've forgotten the 10% part of the tip. At the end you should get $156.86 as your final bill.

A master baker can fill a big order in 6 hours. A student baker can fill the same order in 8 hours. They start working together, and after 2 hours, the student leaves and the master baker finishes the work alone. How long will it take him to finish the order?
Answers
Answer:
It will take the master baker 2.86 hours to finish the remaining order after 2 hours.
Step-by-step explanation:
the time taken for the master baker to fill the order = 6 hours
the time taken for the student baker to fill the order = 8 hours
let the time taken for both to finish the work together if they work at the same rate = x
[tex]\frac{x}{8} + \frac{x}{6} =1\\\\\frac{3x + 4x}{24} = 1\\\\7x = 24\\\\x = \frac{24}{7}\\\\x = 3.43 \ hours[/tex]
After 2 hours, the remaining time for them to finish the work together is given by;
t(remaining) = 3.43 hours - 2 hours = 1.43 hours
Working at the same rate, 2 persons will take 1.43 hours to finish the remaining work.
One person will take hour many hours ?
2 persons working at the same rate --------> 1.43 hours
1 person working at the same rate -----> ?
= 2 x 1.43 hours
= 2.86 hours
Therefore, it will take the master baker 2.86 hours to finish the remaining order after 2 hours.
