Detailed breakdown:
Considering a rectangle measuring 3cm by 4cm with a circle of 1 cm diameter within it:
The area of the shaded section equals Area of Rectangle minus Area of Circle
The area of a rectangle is calculated as Length multiplied by Width

The area of the circle is

Area of shaded region = 12 - 3.142

The pairs that have an HCF of 3 and an LCM of 45 are (3,45) and (15,9).
Answer:
8$
Step-by-step explanation:
Since the initial car wash price remains unchanged, but subsequent washes see a reduction, you only subtract 7 dollars from the total since the discount applies 7 times. Hence, 15-7=8 so 8 dollars is the final amount.
Four statements:
1) Start by dividing the x-axis into equal segments.
2) n = 212/5 = 42.4.
3) Each segment along the x-axis represents 42.4. This means you can plot the point -212 at x = -5
4) The y-axis can keep its magnitude and you can plot the coordinate of -4 at y = -4
When the stretch is proportional to the weight, it can be expressed as:
weight/(49 cm) = (135 N)/(21 cm)
weight = (49/21)×135 N
weight = 315 N
The fish's weight would be 315 N.
