Answer:
80000
Step-by-step explanation:
Here, we want to write the number in one significant figure
What we have to do here is to simply turn the numbers after 8 to zero
This is because the first number is less than 5
So we have the significant figure as 80000
Answer:
The box is 7.5 in long.
Step-by-step explanation:
Calculate the total surface area of the sides of this box (neglecting the ends).
If the base is 3" by 3" and the length of the box is 6", then the total surface area (without ends) is 4 times 3" by x, or 12x in². 80% of this "lateral surface area" is 0.80(12x in²), or 9.60x in° and this 9.60x in² represents the surface area covered b y the label. That label surface area is 4(3 in by 6 in), or 72 in²
Equating 9.60x in² and 72 in² and solving for x yields x = (72 in²) / (9.60 in²:
x = 7.5 in
The box is 7.5 in long.
The simplest form is 1 2/3.
X is equal to 26 —————————-
In part c the answer is 4
