Answer:
Blue Rectangle: <u>135 mm²</u>
Blue Triangle: <u>45 mm²</u>
<em>Not sure if you need this but the </em>Total Square: <u>225 mm²</u>
Step-by-step explanation:
Area of a rectangle: <u>length x width</u>
Area of a triangle: 
<u> x base x height</u>
First find the area of the blue rectangle.
Length = 15 mm
Width = 9 mm
Area = 135 mm²
Now find the area of the blue triangle:
Base = 6 mm (because the bottom is 15 total and you subtract the 9)
Height = 15 mm
Area = 45 mm²
Hope it helps!
Using the formula then calculator to get the ans and we must never forget to write the unit in squared form.
Answer:
v>-2 ( the > is underlined)
Step-by-step explanation:
Answer:
y-2=2/3(x+1) OR y=2/3x+8/3
Step-by-step explanation:
y=2/3x-2 (2/3 represents your slope)
plug into this equation y-y1=m(x-x1) (m represents your slope, y1 and x1 are you points)
so y-2=2/3(x+1) OR y=2/3x+8/3 (move the -2 over, distribute the 2/3 to (x+1) and then add 2/3 to the 2 you moved over)
Answer:
a) Avg rate of change = 4 pounds per week
b) 160 pounds
Step-by-step explanation:
a)
The average rate of change is also called the slope. It is advertised that a person can loose 4 pounds in a week in the program. So, the average rate of change is 4 pounds per week.
Avg rate of change = 4 pounds per week
b)
In 5 weeks, a person can loose:
4 * 5 = 20 pounds (in 5 weeks)
Initially the person weighed 180 pounds, now after the program, he lost 20 pounds, so his weight will be:
180 - 20 = <u>160 pounds</u>
