Answer:
If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:
Step-by-step explanation:
2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.
<u>This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. </u>0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.
I would then say that the estimate of 2 5/6 is 2.83.
Answer:
3.2 units
Step-by-step explanation:
Since the perimeters of the rectangles are equal:
n + n + 0.6 = n +0.1 + 2n
2n + 0.6 = 3n + 0.1
0.5 = n
Left Rectangle:
2 (0.5 + 0.5 + 0.6) = 3.2 units
Since they have the same perimeter, the rectangle on the right also has a perimeter of 3.2 units.
If you have one per box you got 20 broken in all.
Area of circle is πr^2
Diameter is given =20 cm
Radius r=d/2=20/2=10cm
A=3.14×100
A=314 cm^2
