Answer:
7.28 m
Explanation:
Use the Pythagorean Theorem. The length of the ladder is the hypotenuse.
a^2 + b^2 = c^2
a = 2, b = 7, c = ?
Plug in the values into the equation.
2^2 + 7^2 = c^2
4 + 49 = c^2
Square root both sides to get c = 7.28
To solve 3.45 x 10⁹, you have to move the decimal point of 3.45 nine times to the right(---->). Once you do that, you get 3450000000. To solve 0.5 x 10⁴, you have to move the decimal point of 0.5 four times to the right. That equals 5,000. Now the final question is: How many times bigger is 3450000000 than 5,000. So, you divide 3450000000 by 5,000. That equals 690000.
690,000 times bigger than 0.5 x 10⁴
Answer:
Yes!
