i'm guessing u must be from UK.... in the US "standard form" is known as "Scientific Notation"
Write 3.25 x 10^4 as an ordinary number: 32 500
Write 6.04 x 10^-3 as an ordinary number: 0.00604
Write 2 400 000 in standard form : 2.4 x 10^6
Write 0.00147 in standard form: 1.47 X 10^-3
Answer:
OPtion B)
Step-by-step explanation:
3.2 * 10^-4 = 0.00032
So the number is less than 1.
The effect the negative exponent has is.....well...here's an example
if the exponent was a positive it would be 3.2 *10^4 = 32,000
If it was positive you would move the decimal point to the right (for this equation) 4 times... if it was negative you would move it the other way.
Let x=papers on Saturday and y=papers on Sunday
First make equations for the information given to you
x+y=52 (total papers) and y= x+8 (he sold 8 more on Sunday)
then since you know y=x+8 then substitute it in the other equation like so
x+(x+8)=52 which means 2x+8=52 which means 2x=44 and therefore x=22
the problem however asks for sunday and not saturday, so solve for y now
y=x+8 which means y=22+8 which means y=30
He sold 30 papers on Sunday
