Answer:
Let R be the greater radius and r be the smaller radius
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2

Answer:
Step-by-step explanation:
(-x + 3) - (4x - 10)
= - x + 3 - 4x + 10 (because when you see the minus sign you have to change all the sign inside the bracket)
= -5x + 13 (this step is just subtract -x and -4x and 10 + 3)
Answer:
126.4 (rounded to the nearest tenth)
Step-by-step explanation:
53,558/100 = 67739/x
67739*100=53558X
6773900=53558X
6773900/53558=x
126.4070314=X
Use Arizonia as a reference index point. Since it is set at 100, you can put the median income over 100 is equal to California median income over x. Then solve for X.
