Answer:
93.6
Semi circle - 31.81 (rounded)
Step-by-step explanation:
find the area of the triangle which is 1/2 6*5.2 -=15.6
there are 6 triangles so that means it has to be multiplied by 6 - 15.6*6 = 93.6
Use the semi cirlce formula- (pi*r^2)/2
In this situation that is (pi*4.5^2 )/2 = 31.81 (rounded)
C. 30 degrees because it mirrors the angle of P.
Mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling.
Answer:printer=120$
computer=390$
Step-by-step explanation:
printer=x
computer=x × 13/4
x+x × 13/4=510
(4x+13x)/4=510
17x=510×4
x=2040÷17
x=120
y=120×13/4
=390
