Answer:
Quadruple the size
Step-by-step explanation:
Explanation:
When you enlarge a linear measurement by a scale factor a the area changes by a scale factor a2
So when you double the radius. scale factor 2, the area is increased by a scale factor:
22=4
So the area is quadrupled in this case.
Answer:
The equation is
y = $ 12.35 x
Step-by-step explanation:
Cost of one bag of rocks = $ 12.35
Let there are x bags of rocks, so that the total cost is y.
So, the cost of 1 bag = $ 12.35
cost of x bags = $12.35 x
The total cost is
y = $12.35 x
It is the equation of a straight line which passes from origin and the slope is 12.35.
D
its just a basic logarithmic law.
4(9+7) = 36+28 = 64
open the parentheses, then simplify.
