Answer:
Step-by-step explanation:
If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).
The list that orders the fractions from least to greatest is:

Ordering of fractions</h3>
- To order the fractions from least to greatest, we have to realize their conversion to decimal.
- To realize the conversion, the numerator is divided by the denominator, as ordering decimal numbers are easier than fractions.
Hence, the fractions converted to decimal are:
.
.
Hence, the list from least to greatest is, according to the results of the conversions:

An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is multiply each input number
Answer:
AB = 2
BC = 2
A'B' = 6
B'C' = 6
Step-by-step explanation:
L = liz's age now
J = Jack's age now
L-1 and J-1 are their ages one year ago
L-1=3(J-1)
L-1=3J-3
L=3J-3+1
L=3J-2 (to be used later)
L+2 and J+2 are their ages in two years
L+2=2(J+2)
replace L by 3J-2
3J-2+2=2(J+2)
3J=2J+4
3J-2J=4
J=4 is Jack's age now
L-1=3(J-1)
L-1=3(4-1)
L-1=3*3
L-1=9
L=9+1
L=10 is Liz's age now
