To complete this problem, we are going to need to use the Pythagorean theorem.
1.find x. as mentioned earlier, we are going to use the Pythagorean theorum (a²+b²=c²). substitute a b and c for the values on the triangle then solve:
x²+3²=5² substitute
x²+9=25
x²=25-9 subtract
x²=14
x≈3.7 solve to the nearest tenth
2. x is about 3.7km. now we need to find y. to do so, we are going to do the same steps that we did to find x:
y²+3²=7²
y²+9=49
y²=49-9
y²=40
y≈6.3
3. now we know all 3 horizontal side lengths so all we need to do to find the total horizontal distance is add the 3 together:
3.7+3+6.3
13
4. after doing all that math we finally got the answer: The plane's total horizontal distance is about 13km.
I hope this was helpful! :)
First you need to simplify the ratio so divide 3 by 5, to come out with 1:0.6.
Then solve for the unknown then add the unknown to the known for the sum
Just work with it as seperate triangles and then add them up.
Answer:
3.7018867924 × ![10^{-1}](https://tex.z-dn.net/?f=10%5E%7B-1%7D)
Step-by-step explanation:
First you want to find what these two numbers are, then you divide, then you put that answer in scientific notation.
1.728(109) = 188.352
4.8(106) = 508.80
Now we divide :
188.352 ÷ 508.80 = 0.37018867924
That's a crazy decimal, but luckily because of scientific notation we can make it look a lot simpler.
0.37018867924 = 3.7018867924 × ![10^{-1}](https://tex.z-dn.net/?f=10%5E%7B-1%7D)
This should be right. Please comment if you are confused and want more detail.
Answer:
Step 1. Turn the second fraction (the one you want to divide by) upside down
(this is now a reciprocal).
Step 2. Multiply the first fraction by that reciprocal
Step 3. Simplify the fraction (if needed)
Example:
1/2 divided by 1/6
Step 1. Turn the second fraction upside down (it becomes a reciprocal):
1/6 becomes 6/1
Step 2. Multiply the first fraction by that reciprocal:
1/2 × 6/1 = 1×6 / 2×1 = 6/2
Step 3. Simplify the fraction:
6/2 = 3
