we are given
density of gold = 19.3g/cm^3
we know that
we have to change it into kg/m^3
so, we can plug these values
we can also write as
now, we can simplify it
..............Answer
The metric table goes millimeters, centimeters, decimeters, meters, dekameters, hectometers, kilometers. To move up the table, move the decimal point one to the left. If you wanted to change it to centimeters, the answer would be 8,340,000. In kilometers, this is 83.4 kilometers. Hope this helps!
Answer:
it is enough to that all three pairs of corresponding sides are in the same ratio, it is enough to show that they are congruent.
Step-by-step explanation:
7. 3.14(12^2 - 10^2)=3.14(144-100) = 3.14(44)=138.16
8. A = piR^2 = 50.24. R^2 = 50.24/3.14 = 16. R = 4cm
9a) Perimeter of square is 4*18 = 72. Perimeter of circle is 2*pi*r. r=9in
perimeter of circle is then 2*3.14.9 = 56.52. Difference is 72-56.52 = 15.48
9b) Area of square is 18^2 = 324.
Area of circle is 3.14(9^2) = 254.34. Difference is the unshaded part
324-254.34 = 69.66in^2
Answer:
y-(-8)= -6(x-2)
y+8= -6x+12
y = -6x+ 4
you're mistake was you did +8 in 3rd step but you need to -8 both side becoz y-(-8)= y+8
