If an angle is 90 degrees its right, if it's more that 90 degrees its obtuse, if it's less it acute
Kx^2-x-1=0
Kx^2-x=1
Kx^2=1+x
K=1+x/x^2
Answer:
it toke hoh 3 minutes to trave
Step-by-step explanation:
since the given is 48 cm (distance) and 16cm per minute ( speed )
the equation for that is distance over speed
so ... 48÷16 is equal to 3
so it took bob the snail 3 minutes to travel 48 cm
18x/18 = 2/3 • 18
Flip reciprocal of 18 which is 1/18 so it would be 2/3 • 1/18 the 2 and 18 can be simplified when cross multiples so it would then be 1/3 • 1/9 which is x=1/27
Answer:
2300 liters of water.
Step-by-step explanation:
The volume of the barrel is 4.6 m^3, and we know that this is half--filled with water.
Then the total volume of water inside the barrel is:
(4.6 m^3)/2 = 2.3 m^3
So we have 2.3 m^3 of water, and we want to write this in liters.
We know that 1 liter = 0.001 m^3
then:
1 = (1 L)/(0.001 m^3)
Now we can rewrite:
2.3 m^3 = (2.3 m^3)*1 = (2.3 m^3)* (1 L)/(0.001 m^3) = (2.3 m^3/0.001 m^3)* 1L
2.3 m^3 = 2300 L
So we have 2300 liters of water in the barrel.
