Answer:
The answer is x = 1/11
Step-by-step explanation:
hope this helps
10x + 5x – 3 = 2(2x – 1)
10x+5x-3=4x-2
15x-4x=-2+3
11x=1
To find x divide both sides by 11
11x/11=1/11
x= 1/11
If sounds travel 335 meters in 1 second , in 1 minute it travels 60 times that distance :
335m × 60 = 20100 meters
Sounds travel 20100 meters per minute
if 1000 meters = 1 km ,
20100 meters = 20100/1000 km
20100 meters = 20.1 Km
Awnser : Sound would travel 20.1 km in one minute
I thought doubling everytime except for the number 19000 because if you do 250 × 2 = 500 so then you do 500×2=1000.
Electric current? Why is the thing math lol.
Answer:
The answer is 
Step-by-step explanation:
Assuming the snowball is a perfect sphere, then if A denotes the surface area and D the diameter then:
Differentiating wrt r we have:
We are told that 
and we want to find 
By the chain rule we have:
∴
∴
When D=10 then
The sign (-) shows that the D is decreasing.
