Explanation:</h2>
As I understand, you need to know the relationship between the area of similar figures. Two shapes are similar if we can turn one into the other by moving, rotating, flipping, or scaling, so this means we can make one shape bigger or smaller.
From math, if we call
the scaling factor, then the area of one figure (
) divided by the area of another similar figure (
) will be equal to the scaling factor squared. In other words:

The answer in the simplest form is 7
Answer:
1) 81.64 ft 2) 12.56 in
Step-by-step explanation:
a radius is a line <em>halfway</em> through the circle starting in the middle... a diameter is double that, or a line that goes <em>all the way </em>through the circle
you are working with diameter
in order to find the circumference of a circle using diameter, the equation is
C (circumference) = pi x d (diameter)
in order to find the circumference of a circle using radius, the equation is
C = 2 x pi x R (radius)
Answer:
Jan brought 44 cookies
Step-by-step explanation:
To solve this problem, we need to work backwards. First, we have 10 cookies left at the end of the day. At lunch, she gave away 12 cookies. This means that Ms. Jan had 22 cookies at lunch since
10
+
12
=
22
In the morning, Ms. Jan gave out half of her cookies. This means that she started with twice as many cookies as she had at the beginning of lunch.
22 x 2
=
44
Ms. Jan brought 44 cookies.
Answer:
x=-3, x=1, x=3.5, and x=5
Step-by-step explanation:
Given the critical points (turning points) which represent the maximum or the minimum points, the set of points that can be tested to solve the inequality will consist of points to the right and to the left of these points. The set of points that solve the inequality will be simply the points where the graph of the function crosses the x-axis. From these information, the set of points will be as given above
