Scale factor is:
factor = (new length) / (old length)

Answer:
2299 in^2
Step-by-step explanation:
The formula for the volume of a square pyramid of base A and height h is
V = (A)(h).
Here, the perimeter of the base is 44 inches, so that the length of one side must be (44 in) / 4, or 11 in. The area of a square of side s is A = s^2, so we have:
Here, V = (11 in)^2 * (19 in) = 2299 in^2
answer: 6.4
work:
Solve the problem.
Let's start by solving the numerator,
(5 + 3)² <em>step one: add 5 + 3 </em>
(8)² <em>step two: simplify 8²</em>
64
now, let's simplify our denominator
1 + 2⁵ - 23 <em>step one: simplify 2⁵.</em>
1 + 32 - 23 <em>step two: add 1 + 32.</em>
33 - 23 <em>step three: subtract 33 - 23</em>
10.
now, put the numerator back over the denominator.
64/10
let's simplify by dividing, we get 6.4.

Answer:
substitute y = mx +b = (2/3)x -2
Step-by-step explanation:
slope intercert form looks like this
y = mx + b
m is the slope
b is the y intercept
The line intercepts the y at -2
To find slope, pick 2 points to find the slope
m = (y2 - y1)/(x2-x1)
i select point 1 (0,-2) and point 2 (3,0)
m = (0-(-2))/(3-0) = (2)/3
substitute y = mx +b = (2/3)x -2
