I don’t really understand ur question but the fraction 2/10 in simplest form is 1/5
Answer:
Step-by-step explanation:
Lets find out first the Area of the rectangle building
A=50*100=5000 ft^2
we have 2 circles with the radius of 42 ft, r=21ft
Acircle=3.14*(21)^2=1384.74
Area of 2 circles=2*1384.74=2769.48
What is not covered by the rings is
5,000.00-2769.48=2230.52, rounded is 2231
Choice A
Looking at the values given for Flouride (mg), we have the lowest value of 0.4 and the highest value of 7.1
The axis should start at 0 and the least number it should go up to is 8
Looking at the values in between 0.4 and 7.1, we have 1.6, 2.5, 3.1, 4.5 and 6.8
Ideally, we want the scale that makes it easier to read this values, the smaller the scale is the better.
Answer: 0 to 8 with intervals of 0.2 (C)
Because the square root of 49 is seven, you now have to squared values that can be used
So 1-7^2c^2
And now, because of the negative, you will have
(1-7c)(1+7c)
56ft. Because 7 times 8 is 56.
