Answer:
128
Step-by-step explanation:
If the area of a figure is 32 square centimeters then the length/breadth could be 8cm and 4cm or 16cm and 2cm.
Let’s assume that the the sides of the figure are doubled, if that’s the case then we would arrive at 8*2 * 4*2 or 16*2 * 2*2 in which 16*8 or 32*4 which will both result to 128 as the answer.
60 minutes in an hour.
1/4 × 60 = 15
3 quarters of an hour is
3 × 15 = 45 minutes
1. <span>-0.9x+2.8=4.1
First subtract 2.8 from both sides.
-0.9x = 1.3
Now divide both sides by -0.9.
x = -1.4444..
This can be rounded to -1.44
</span><span>c) -1.44

Answer:
C. 380
Step-by-step explanation:
Area of the tabletop = area of a circle
Area of a circle = πr²
radius (r) = ½*diameter = ½*22 = 11 in
Take π as 3.14
Plug in the values into the formula
Area of tabletop = 3.14*11² = 379.94
Area of tabletop would be approximately 380 in² (to nearest whole number)
