The absorbance of the solution at 710nm increases so that it off the scale of the spectrophotometer (values > 2). To correct for these values, we must adjust the absorbances so that the correct values can be calculated. To do so a ratio of the highest accurate absorabance can be used to determine the extinction coefficent of 710 nm. Solve for this value based on absorbances using tube 6.

step-by-step explanation:

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
