Answer:
Bridge = 300 m
Speed = 10 m/s
Step-by-step explanation:
If a goes past you in 10 seconds, it means the train has speed of
100 m/ 10 seconds as it is 100 m long
<u>The speed in m/s is:</u>
Then it take 3 times of 10 seconds to cross the bridge, so
<u>The length of the bridge is:</u>
Answer:
45 days
Step-by-step explanation:
first Project using 45 workers, is finished in 15 days.
that is 15(45) = 675 worker•days of labor
second project is expected to take 675 worker•days of labor to complete as well
675 worker•days/ 15 workers = 45 days
Answer:
The real-world scenario is given as: A yacht traveling 20 miles due east off a harbor is located 50 miles due north from the yacht
Recall:
Pythagorean Theorem applies to a right triangle where and c is the hypotenuse.
If we know the two of the three side lengths of a right triangle, we can find the other third length.
An example of a scenario where the Pythagorean Theorem can be applied to solve a real-world problem can be sketch in a diagram
Therefore:
The real-world scenario is given as: A yacht traveling 20 miles due east off a harbor is located 50 miles due north from the yacht

2.5, because 6 2/3 - 4 1/6....
First, find the most common denominator! Which is 6.
Multiply the bottom term to 2 times. (To get 6.) Now do the same for the top! So 6 4/6 - 4 1/6
Second, you subtract!
2 3/6
Third, if your teacher has ever taught you this or not....
If she did: Simply 2 3/6 into 2 1/2!
Finally,
2 1/2 can be 2.5, 2 3/6, or just 2 1/2!
