5 is in the ones place so u round up
-100-70+100-30=-100
I included the value of the merchandise that she "purchased", so the owner lost $100 in total value.
Answer: Density
This measurement tells you how packed in a substance is. The higher the density, the more the object weighs for a certain volumetric unit (such as a cubic meter). Eg: a cubic meter of feathers is likely to weigh less than a cubic meter of solid gold because the feathers have a lot more air in them as opposed to the gold which is more compact.
density = mass/volume is the formula you often use
In order to answer this, it would be useful to calculate the area of the cardboard and the circles. We do as follows:
Total area of cardboard = <span> 8.0 in. x 11.0 in = 88 in^2
Area of one circle = pi(r^2) = pi(0.5)^2 = 0.7854 in^2
Number of full circles = 88 / 0.7854 = 112.0451
Therefore, there will be 112 number of full circles. The percentage of waste is equal to:
% waste = (88 - 0.7854(112) / 88) x 100= 0.04%</span>
Answer:
1
Step-by-step explanation:
using the reciprocal rule
3/11÷3/11
thats the same as
3/11×11/3
3×11=33
11×3=33
33÷33=1
