Area of the triangle = (1/2)*base*height
For right triangle base and height can be legs.
We have one leg = 5 ft. (Lets think it is a base.)
We need to find the other leg.
We are going to use Pythagorean theorem.
5² + b²=13²
b²=144
b=12 (It is going to be our height.)
Area of the triangle = (1/2)*5*12= 30 ft²
Area of the triangle = 30 ft²
Answer:
47.2 miles per hour
Step-by-step explanation:
472 miles/ 10 hours= 47.2
Answer:
B - 600 words in 12 minutes
Step-by-step explanation:
So most of this has to do with division. So let's look at answer one
320 words in 8 mins
320/8 = 40 words per minute.
600 words in 12 minutes
600/12 = 50 words per minute
350 words in 8 minutes
350/8 = 35 words per minute
And finally, 225 words in 5 minutes
225/5 = 45 words per minute. Thus, the answer is B
Answer:
The third answer that is C is correct
Answer:
22.14
Step-by-step explanation:
Using the Pythagorean Theorem:
a^2 + b^2 = c^2
21^2 + 7^2 = c^2
441 + 49 = c^2
490 = c^2 (square root both sides so c^2 becomes c)
c = 22.13594363 (round to hundredths)
c = 22.14
