A glacier in Alaska moves about 29.2 meters a day. About how much farther will it move in 1,000 days than it will move in 100 days?

26.28km further

Step-by-step explanation:

Step one:

given data

distance moved in a day= 29.2 meters

for 1000 days the  glacier will move  x meters

cross multiply

x=29.2*1000

x=29200m

x=29.2km

distance moved in a day= 29.2 meters

for 100 days the  glacier will move  x meters

cross multiply

x=29.2*100

x=2920

x=2920m

The difference in distance between 1000days and 100days is

=29200-2920

=26280

=26.28km

26.28km further

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
