d) 0.48 – 0.00097
8) select the expression that is equivalent to (4 x 10^3)(5x10^7).
a) 4.5 x 10^3+7
b) (4+5) (10^3+10^7)
c) 4.5 x 10^3x7
d) ( 4 x 5) (10^3+10^7)

6: d, 7: b and c, 8: a

Step-by-step explanation:

6) The answer is (d).

We have,

0.00001131 =1.131×0.00001

= 1.131/100000

= 1.131×10^-5.

So, this is correct answer.

7) This question have two answers (b) and (c), both are correct.

(b) 480000-97000

= 4.8x100000-9.7x10000

=4.8x10^5-9.7x10^4

(c) 4.8x10^5-9.7x10^4

= 4.8x10^5-0.97x10^5

= (4.8-0.97) x10^5

=3.83x10^5

8)(a)

(4 x 10^3)(5x10^7).

= 4x5x10³x10^7

= 4x5x10^(3+7).

answer: was that a question or answer?

step-by-step explanation:

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
