A ship leave port and sails 12 km west, then 19 km north. Approximately how far is the ship from the port?
2 answers:
Answer: 22Km
Step-by-step explanation:
H^2=19^2+12^2
H^2=361+144
H^2=505
Then find the square root of both sides
H=Square root(505)
H=22km(to a whole number)
Answer:
22.47km
Step-by-step explanation:
first it travels west
then north therefore
it takes a turn at right angles
so the route forms a right triangle.
12 & 19 are the legs and the actual distance the hypotenuse.
use pythagoras theorem so
12^2+19^2=d^2
144+361=d^2
505=d^2
d=sqrt(505)
d=22.47 km

Step-by-step explanation:
If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount
30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.
Answer:
x=12
Step-by-step explanation:
For the given situation , a quantity x is added to
gives 15.
We can set up equation as

Multiply each term by 4 on both sides to get rid the denominator.
It gives,
4 x+x=60
Now, combine like terms
5 x=60
Divide both sides by 5
x=12.
