Answer:
Step 1 :
Split the figure into 3 parts
part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in
part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in
Part 3 :Rectangle with breadth 2in and length 9in
Step 2 :
find the area of each part
Area of part 1
Area of part 2
Area of part 3
Total area = 52.5 + 88 + 18 = 158.5 sqaure inches
Answer: number of kids(k)=200
sand the number of adults(a)=300, visited the carnival.
The tool I used is called simultaneous equation and I used elimation method as the method.
Sin²β +cos²β=1
cos²β=1-sin²β
cos²β=1-(4/7)²
cos²β=1-16/49=49/49-16/49=33/49
cosβ=√33/√49=√33/7
Answer:
Parallel: y=6x-19
Perpendicular: y=-1/6x-0.5
Step-by-step explanation:
To be parallel to a line, the slope must be the same as the line. Then, you plug 3,-1 into y=6x, and add or subtract to balance the equation. You do the same to find the perpendicular line, but the slope must be the negative reciprocal of the line it is perpendicular to.
