How many times larger is 9 × 10^8 than 3 × 10^-5? a. 3 × 10^13 b. 3 × 10^-40 c. 3 × 10^-13 d. 3 × 10^3

A. 3 × 10¹³

Step-by-step explanation:

We have the numbers, 9 × 10⁸ than 3 × 10⁻⁵.

To find the factor by which 9 × 10⁸ is greater by 3 × 10⁻⁵ is given by,

i.e.

i.e.

So, 9 × 10⁸ is 3 × 10¹³ times greater than 3 × 10⁻⁵.

i.e. 3 × 10⁻⁵ × 3 × 10¹³ = 3 × 3 × 10⁻⁵⁺¹³ = 9 × 10⁸.

Hence, option A is correct.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
