%change=100(final-initial)/initial
You can plug in your values...if you meant initial=12 and final=36...
%change=100(36-12)/12=200%
Since it is positive, that is a 200% increase.
Answer:
Harriet is 16 years of age

x=21
21-5=Harriet's Age
Answer:
Step-by-step explanation:
i dont really get the question but
16 mm = 1.6 cm = 16/10 cm = 8/5 cm
First add what is in the parenthesis. Which would be 14+34=48
Then multiply that by 3. 3 x 48=144
Answer:
24 inches
Step-by-step explanation:
Similar to the question you asked earlier, this question also has 3 small rectangles and we can combine it to make it a one big rectangle. The equation for the perimeter is this:
2W + 2L = P
We know W and P (the width of the small rectangles times 3), thus plugging in those values would give us:
2(30*3) + 2L = 324
180 + 2L = 324
2L = 144
L = 72
We need to divide this number by 3 to get the length of the small rectangle, which would give us 72/3 or 24.
