Answer:
The perimeter of the garden is 126.81 feet.
Step-by-step explanation:
We are given the following in the question:
Dimensions of rectangle:
Length, l = 33 feet
Width, w = 21 feet
Dimension of semicircle:
Diameter of circle, d = 33 feet

Perimeter of garden =

Thus, the perimeter of the garden is 126.81 feet.
Answer:
The lemonade costs 1.4.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x is the cost of a cookie.
y is the cost of a lemonade.
Total cost for cookie and lemonade is 1.80.
This means that
.
As we want y, we have that 
Lemonade costs 1.00 more than the cookie?
This means that:

So




The lemonade costs 1.4.
The answer is 2.1 US dollars,

Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° =
= 
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )
