Answer:
$7
Step-by-step explanation:
just did 21 divided by three since it says she has saved one third of the $21.
Answer: 42.14 cm^2
square:
Area of a square=s^2
A=14^2
A=196
circle (the two semi circles are the same as one circle):
Area of a circle=(pi)(r)^2
divide 14 (diameter) by 2 to find the radius
A=(3.14)(7)^2
A=(3.14)(49)
A=153.86
subtract the area of the two semi circles from the area of the square to get the answer
196-153.86=42.14
5+6 is 11 and 11-9 is 2
and also
6-9 is -3 and -3+5 is 2
so it is 2
You first simplify
tan(x) = cos(x)/sin(x) and cot(x) = sin(x)/cos(x)
Then you plug that in and then you simplify even more
10/8 can be simplified to 5/4, which is the same as 1.25 (divide numerator 5 by denominator 4).
So you have x>1.25.
All numbers greater than 1.25 are possible solutions.
