What is the total weight in pounds of a 2.5 million blocks used to build the great pyramid and then convert that to ounces

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
