5 × 10 to the power of 22 is how many times greater than 1 × 10 to the power of 21
alekssr [168]

Answer:

50 times greater

Step-by-step explanation:

If there are two numbers A and B, where A is greater than B,

If we want to find how many times greater A is to B, we simply divide, so that would be

A/B

Now, we have

5*10^{22}

and

1*10^{21}

We simply need to divide to find how much greater is the first number than the second number. Remember dividing numbers in scientific notation:

\frac{a*10^b}{c*10^d}\\=(\frac{a}{c})*10^{b-d}

Thus, we have:

\frac{5*10^{22}}{1*10^{21}}\\=(\frac{5}{1})*10^{22-21}\\=5*10^{1}\\=5*10\\=50

So the first number is 50 times greater than the second

What is the value of x, the side length of the smallest square (please show work) Thanks!
Ratling [72]

Answer:

8 cm

Step-by-step explanation:

Ok lets on the biggest square we have 17 cm

17cm is the hypotenuse for the right triangle

The second largest's area is 225 cm^2

Sq root of 225 cm^2, is 15

To find x, lets plug the info we have to the pythagorean theorom

a^2 + b^2 = c^2\\a^2 + 15^2 = 17^2\\a^2 + 225 = 289\\\\289 - 225 = a^2\\64=a^2\\a = 8 cm

The side length of the smallest Square is 8 cm

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
