Answer:
see below
Step-by-step explanation:
Significant figures are numbers that are necessary to express a true value.
Place the values in scientific notation.
Explaining <u>why</u>
1. The zero that is within 5.6803 is "trapped," meaning it is in between two nonzero digits. Therefore, all five digits are significant figures.
2. The zeroes that precede the 4 and the 7 are not significant because they are dropped in scientific notation and are not trapped by other nonzero digits. Therefore, only two digits of this value are significant.
3. Because the zero at the end of 0.240 is a trailing zero, it is significant along with the 2 and the 4. The zero that precedes these digits and the decimal point is not significant. Therefore, only three digits of this value are significant.
Hope this helps! :)
Answer:
The total amount of floor space in the building is
Step-by-step explanation:
we know that
A building has 217 floors. Each floor has 505 square feet of floor space
so
To find out the total amount of floor space in the building, multiply the area of one floor by the number of floors of the building
Let
x ------> area of one floor of the building in square feet
y -----> number of floors of the building
z -----> the total amount of floor space in the building in square feet
we have
substitute
