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
Answer: Yes. On average, it takes about 455 days for 1 person to throw away 1 ton of garbage, so just over 1 year.
Step-by-step explanation: The average person throws away 4.4 pounds of trash daily. So, the way to figure this out is 2,000 divided by 4.4 to find out the number of days it would take to throw away 2,000 pounds of trash.
The measure of 1 and 3 would be =90
answer: 50°
If triangle is isosceles than L and J are same angles
3x + 20 = 4x + 10
3x-4x=10-20
-x = -10 (divide both sides by -1)
x=10
angle L=J = 3*10+20= 50
we can calculate it like this too 4*10 +10= 50
