4 significant figures. All figures are significant because the zeros are in between two significant digits
Answer:
the answer is (7.5,0) happy cheating to y'all lol
Step-by-step explanation:
Area (square mirror)=side²
Therefore:
side²=256 in²
side=√(256 in²)=16 in
Rectangular mirror:
width= square mirror width=side=16 in
length=(width + 2 in)=16 in + 2 in=18 in.
Area(rectangular mirror)=length x width.
Area (rectangular mirror)=(18 in)(16 in)=288 in².
Answer: the area of a rectangular mirror is 288 in².

Answer:
3,400,000
Step-by-step explanation:
refer to attached for reference
in our case, the digit in the hundred thousands place is the number 4.
How we round this digit depends on the digit directly to the right of it (i.e the ten-thousands place).
If the digit to the right is less than 5, then leave the digit in the hundred thousands place the same and make everything else to the right zeros.
if the digit to the right is 5 or greater, then increase the digit in the hundred thousands place by 1 and then make everything else to the right zeros.
in our case, the digit to the right of the hundred thousands place is the number 2, this is less than 5, so we leave 4 the same and make everything esle to the right zero.
i.e. 3,400,000
