Answer:
12
Step-by-step explanation:
Using the pythagorean theorem we have DE^2 + 5^2 = 13^2
DE^2 = 169 - 25 = 144
DE = sqrt144 = 12
Or, you could just remember the triangle 5-12-13, as it is pretty common, along with 3-4-5, 7-24-25
Let y directly proportional to X
thus y = CX
where c is proportionality constant
given c= 9
thus y = 9x
Answer:
180
Step-by-step explanation:
Let's first just do the multiplication and ignore the decimal points.
2073 x 4 = 8292.
Now there are 3 decimal points we need to consider. So, that gives us an answer of 8.292
