Answer:
a) 1.59967 * 10 ^-12
b) 7.52711497
c) 1.590778098 * 10^-1
Step-by-step explanation:
a= 3.47 x 10^-6,
b=4.61 x 10^-7,
c=5.52 x 10^-7
a) a*b = 3.47 x 10^-6* 4.61 x 10^-7
We multiply the numbers out front and add the exponents
(3.47*4.61) * 10^(-6+-7)
15.9967 * 10^-13
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the left and add 1 to the exponent
1.59967 * 10^(-13+1)
1.59967 * 10 ^-12
b) a/b = 3.47 x 10^-6/ 4.61 x 10^-7
We divide the numbers out front and subtract the exponents
(3.47/4.61) * 10^(-6- -7)
(3.47/4.61) * 10^(-6+7)
.752711497* 10^1
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the right and subtract 1 from the exponent
7.52711497* 10^1-1
7.52711497
c) c/a = 5.52 x 10^-7/3.47 x 10^-6
We divide the numbers out front and subtract the exponents
(5.52/3.47) * 10^(-7- -6)
(5.52/3.47) * 10^(-7+6)
1.590778098 * 10^-1
Well 4% of 250 is 10 so i think the answer is 240 to 260 right?
Answer:
yes, you did
Step-by-step explanation:
When it's x= a number the line is vertical and when it's y= a number it's horizontal.
Not all of the student body would have responded therefore her conclusion was incorrect, could be changed to be right by saying 90% of people who responded to a survey said the school colours should be changed.
The product would be the dividend, and either the factors would be the divisor. the quotient will be the other factor as well. hope this helps
