7.50 x 8 = 60
9.25 x 9 = 83.25
83.25 + 60 = 143.25
143.25 - 20.68 = 122.57
Part A : 122.57
122.57/4 = 30.64
122.57-30.64 = 91.93
Part B : 91.93
Answer:
-40
Step-by-step explanation:
Plug in 9 for x.
Use Order of operations
-10(9) = -90
-90 + 50 is the same thing as saying 50 - 90
we can simplify by splitting the -90 in to a -40 and a -50
the new equation could be 50 - 50 -40.
50 - 50 = 0
0-40 = -40
4 thousands equals 40 hundreds.

Answer:
5π m
Step-by-step explanation:
Using the pythagorean theorem we can figure out that the third side is 5m
A^2 + B^2 = C^2
3^2 + 4^2 = C^2
9 + 16 = C^2
25 = C^2
√23 = √(C^2)
C = 5m
Side C is also the diameter of the circle, so the radius is 5/2, or 2.5
From that we can use the circumference formula, Circumference = 2π<em>r</em>
Circumference = 2 π (2.5) = <u>5π m</u>
