(2 × 10^7) + (3 × 10^4)

= (2 × 10^7) + (0.003 × 10^7) . . . . make the exponents match

= (2 + 0.003) × 10^7

= 2.003 × 10^7

The appropriate choice is ...

... b. 2.003 × 10^7

Step-by-step explanation:

Use the pythagorean theorem!

(think that is how you spell it )

Pythagorean theorem: a² + b² = c²

a and b are the numbers that you have in this example, c is the side you need!

75² + 40² = c²

5,625 + 1,600 = c²

7,225 = c²

$\sqrt{7,225} = \sqrt{c}^{2}$

(the square root and square cancel each other out)

85 = c

c = 85

A coroner arrives at a murder scene at 10p.m. She finds the temperature of the body to be 86.3 degrees F. She waits one hour, t

hram777 [196]

5 - 6 pm

if the temperature drops 3 degrees per hour. so how many hours would it take to go from 98.6 to 86.3

98.6-86.3=12.3

3 goes into 12 4 times.

10 pm - 4 hours is 6pm.

if you figure in the .3

you come to approximately 5pm
