Answer:Number of squares colored red= 180-40= 140 squares
Step-by-step explanation:
Hannah has a grid of squares that has 12 rows with 15 squares in each row. This means the length of the gris is 15 squares and the breadth is 12 squares.
Area of grid = length × breadth
=15×12 = 180
She colors 5 rows of 8 squares in the middle of the grid blue. This means the part coloured blue has a length of 8 squares and breadth of 5 squares.
Area of blue colored part = 8×5 = 40
Number of squares colored red= total number of squares - number of square colored blue= 180-40= 140 squares
Inscribed angle is half of the subtended arc so…..
85/2 =
42.5
Slope-intercept form is y=mx+b
m is slope and b is y-intercept.
So, if you have -5x-3y=3
Make it into y=something
So, -3y=3+5x
y= -3/3 + 5/-3 x
y= -1 - 5/3 x
Same as the first one in your pic.
I would say that his estimate is not reasonable because the price of the 5 cucumbers is $3.10. When you estimate, you round to the nearest tenth.
Hope this helps :D
