Answer:

2.17 \times 10^{-1}

Step-by-step explanation:

(7 \times 10 ^{-6}) + 0.26 - (5 \times 10^{-2}) = \frac{7}{10^3} + \frac{26}{10^2}-\frac{5}{10^2}

                                              = \frac{7 + (26 \times 10) - ( 5 \times 10)}{10^3}\\\\=\frac{7 + 260 - 50 }{10^3}\\\\=\frac{217}{10^3}\\\\= 2.17 \times 10^2 \times 10^{-3}\\\\= 2.17 \times 10^{-1}

A square has a side of 6.25 feet. What is the area in square feet? Round to the correct significant digits.
sveta [45]

All sides of the squares are congruent. This means that when solving for area:

base x height

the base and height would be the same length, 6.25

Multiply

6.25 x 6.25 = 39.0625

39.0625 ft² should be your answer (if i'm thinking of significant digits correctly)

If it should be a whole number, then 39 ft² is your answer

hope this helps
