Step-by-step explanation:
the circumference of a wheel is one revolution
so
formula: circumference=π*diameter
D=26cm (13*2 to find the whole length from one end to other)
so you'll do 3.14*26 equals 81.64
one revolution=81.64
30 revolutions=2,448.3 inches (times by 30 with 81.64)
Answer:
x = 100
Step-by-step explanation:
I know that the total is 180 so with that in mind this is what i did to get the answer.
180 - 57 = 123
123 - 23 = 100
Double check your work
100 + 23 = 123
then 123 + 57 = 180
your answer is 100:)
hope this helped!
The answer is ou need to rewrite the equation to make it easy... and let it equal zero
<span>2<span>x2</span>−8x+4=0</span>
which will become
<span>2(<span>x2</span>−4x+2)=0</span>
you need to solve
<span><span>x2</span>−4x+2=0</span><span>
by completing the square or the general quadratic formula.</span>
