8. Multiply the following numbers using scientific notation: (2 x 10^3)(2 x 10^4).

9. Divide the following numbers using scientific notation: (4 x 10^2)/(1 x 10^3)

10. Perform the following calculation: (1 x 10^2)(2 x 10^3)/(1 x 10^2)

Question 8

Multiply the following numbers using scientific notation: (2 x 10^3)(2 x 10^4).

(2 x 10^3) = 2*10*10*10 = 2000

(2 x 10^4) = 2*10*10*10*10 = 20000

2000*20000

=40 000 000

=

Question 9

Divide the following numbers using scientific notation: (4 x 10^2)/(1 x 10^3)

(4 x 10^2) = 4*10*10 = 400

(1 x 10^3) = 1*10*10*10= 1000

400/1000 = 0.4

=

Question 10

Perform the following calculation: (1 x 10^2)(2 x 10^3)/(1 x 10^2)

(1 x 10^2) = 1*10*10= 100

(2 x 10^3) = 2*10*10*10 =2000

100*2000 = 200 000

(1 x 10^2) = 1*10*10 = 100

200 000/100 = 2000

=

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

Ithink the right answer could be 50%
