Multiply 20 by 10 first
Then 200 by 30 which is 6000
Then 6000 by 40 which is 240000
Basically just multiply the numbers that's aren't 0
Like 2 in 200 times 3 in 30
Which is 6 then add the 0s so 6+000=6000
Answer:
Please see below.
Step-by-step explanation:
f^-1 (x) essentially means the reverse.
We can substitute y for x in the equation and solve for y:
x = 4y -1
x+1 = 4y
y = (x+1)/4
so that is our answer for the first one:
f^-1(x) = (x+1)/4
We do the same trick for the second question:
x = 2y +1
x-1 = 2y
y = (x-1)/2
so the answer is f^-1(x) = (x+1)/2
The last question is slightly more complex, we can write is as:
x = 2y/(y-1)
x(y-1) = 2y
yx -x = 2y
yx = 2y + x
yx - 2y = x
y(x-2) = x
y = x/(x-2)
so the answer is x/(x-2)

So you have to add up all of the cars which would be 18 and then he sees hybrid which is 4 so 4/18 but you have to simplify which would be 2/9
one inch---> 24.4 cm
inches in 24.4cm=> 24.4/2.5
=> 9.76cm (2 decimal places)
Remember the equation to find the circumference?
Equation of circumference: Pi x 2(radius)
Therefore, 3.141592654 x 2(6ft) = 37.7 feet
