Answer:
15 inches
Step-by-step explanation:
1. Use the Pythagorean Theorem: a^2+b^2=c^2
You are already given c (the longest side) and one of the legs which could be a or b.
2. Plug the numbers into the formula and square them.
a^2 + 36^2 = 39^2
Squaring the numbers gives you: a^2 + 1,296 = 1,521
3. Subtract 1,296 from both sides and take the square root of the result.
a^2 = 225
= 15
Answer:
5.3
You split them up into smaller root numbers and add them together
The answer is A should be right
Answer:
3 days
Step-by-step explanation:
First multiply 10 by 400 to find how many meters she runs each day.
10*400 = 4,000
1 kilometer = 1,000 meters
Now convert the meters to kilometers
To convert it to kilometers you divide 4,000 by 1,000, which equals 4 kilometers.
So she runs 4 kilometers each day.
Now divide 12 by 4 to find out how many days it will take to run 12 kilometers.
12/4 = 3 days
Answer:
y = 1/15
Step-by-step explanation:
3y + 1/5 = 2/5
Subtract 1/5 from each side
3y +1/5 -1/5 = 2/5 -1/5
3y = 1/5
Multiply by 1/3
3y *1/3 = 1/5 *1/3
y = 1/15
