Answer:
length of a single chain link = 5.33 cm
Step-by-step explanation:
Given data: chain contained 1000 chain links
total length was 0.0533km
<em>1km = 1000m </em>
<em> 1m = 100cm therefore 1km = 100000cm</em>
<em />
total length in cm = 0.0533* 100000
total length in cm = 5330 cm
length of a single chain link = 5330/1000
length of a single chain link = 5.33 cm
Answer:
Actual Height = 27.11 m
Step-by-step explanation:
Given:
Height of model rocket = 4.5 % of actual Height
Model Height = 1.22 m
To Find:
Actual Height of rocket = ?
Solution:
We have to Find the Actual Height of the rocket
Let actual height be x
Now it is given that
Height of model rocket = 4.5 % of actual Height
As we have the values so putting it in it becomes
1.22 = 4.5 % * x
it could be written as
Multiplying both sides by 
it becomes
1.22* = x
= x
27.11 m =x
or
Actual Height = 27.11 m
Answer:
you can't find the square root of a negative
Step-by-step explanation:
Put the numbers in the given equation and solve for k.
... $11 = k·(8 €)
Divide by the coefficient of k:
... k = $11/(8 €) = 1.375 $/€
Then your equation is ...
... y = (1.375 $/€)x
_____
It is fairly common to leave the units out of such equations, assuming that everyone understands that x is in euros and y is in dollars and the conversion factor includes a unit change from euros to dollars. Thus, you might expect to see ...
... y = 1.375·x
Answer:
3x
I had trouble imagining it, so I plugged in 3 as x. My answer when I solved for radius was 9, or in other words, 3x because x was 3.
