Answer:
Top-to-bottom, the boxes have this order in the proof: 1, 7, 4, 3, 9, 8, 5, 2, 6.
Step-by-step explanation:
The basic idea is to use the Pythagorean theorem to write two expressions for the length of altitude BD, also called "k", then equate them and simplify the result. This leaves an expression for DC, also called "x", which is replaced by a cosine expression to complete the proof.
Finally, the variations involving other combinations of sides and angles are suggested as being provable in the same way.
Answer:
x = 131,25 m
Step-by-step explanation:
Manufacture the collar of an airbag helmet takes 1,5 m of fabric
Manufacturer is going to make 250 collars
Company only has 65 % of the needed fabric
Total quantity of fabric needed is:
250 * 1,5 = 375 m
If they have 65 % that means that they need 35 % of the total quantity
then, by rule of three
375 ⇒ 100
x ?? ⇒ 35
x = ( 375 * 35)/100
x = 131,25 m
Answer:
It is linear and it is so named because when we graph this equation, it shows up as a straight line.

Answer:
speed of light is 3 x meters per second.
Step-by-step explanation:
Given : The speed of light is 3 x kilometers per second.
To find : What is that in standard form.
Solution : We have given 3 x kilometers per second.
First we convert it in to meter per sec.
We can write
3 x = 300000 kilometer per second .
We know that 1 km = 1000 meter.
Then 300000000 meter per second
Now, 3 x meter per second.
Therefore, speed of light is 3 x meters per second.
