100 cm = 1 meter
210 cm = 2.1 meters (multiply both sides by 2.1)
Mary uses 2.1 meters of thread so far, meaning she has 10-2.1 = 7.9 meters left
7.9 meters = (7.9 m)*(100 cm/1 m) = 790 cm
--------------------------------------
Alternate route:
10 meters = (10 m)*(100 cm/1 m) = 1000 cm
Mary uses 210 cm out of 1000 cm total, so she has 1000-210 = 790 cm left.

<h3>Answer: 790 cm</h3>
The population is increasing by 1500 each year and starts at 1970 population ( = 4800) so the equation is
y=1500x+4800
C. is not a function since all the F9x) numbers are identical
Answer:
9t^3 +t^2
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of the sides. The side lengths are represented by the polynomials shown, so the perimeter (P) is their sum:
P = (4t^3 -5) + (4t^3 -5) + (t^2 +9) + (t^3 -t^2 -11) + (t^2 +12)
Rearranging to group like terms:
P = (4t^3 +4t^3 +t^3) + (t^2 -t^2 +t^2) + (-5 -5 +9 -11 +12)
P = 9t^3 +t^2
The perimeter of the figure is represented by the polynomial 9t^3 +t^2.
