The common difference is 4. U know that the formula is the first term + d(n -1). N-1 is 14 so u know that 14 times a number needs to equal 56 because the first term is -3 and 56-3 is 53. 14 * 4 is 56. So the common difference is 4

Answer:

3.2 x 10^13

Step-by-step explanation:

(8x10^4)(4x10^8)

reorder the terms using the commutative property

(8x4)x(10^4x10^8)

multiply

32x (10^4 x 10^8)

= 32 x 10^4+8

= 32 x 10^12

now convert to scientific notation

=3.2 x 10^13

33.3% coverted into a decimle and fraction
valkas [14]
-- To change a percent into a decimal, move
the decimal point two places this way    <== .

                     33.3%  =  0.333 .

-- To change a percent into a fraction, remember
that the symbol  ' % '  means  ' /100 ' .

                     33.3 %  =  33.3/100 .

That fraction looks ugly, because it has a decimal in the numerator.
That's easy to fix.  Multiply top and bottom by  10, and you have

                                       333/1000 .
