Mrs. Téllez has a roll of wrapping paper in her gift shop. She uses 1/4 yard to wrap each gift. If there are 20 yards of wrapping paper on the roll, how many gift of the same size can she wrap until the roll is empty ?

She would wrap 80 gifts

Step-by-step explanation: Mrs Tellez has a roll of wrapping paper that is 20 yards long. For each gift she wraps she uses up one-quarter of a yard (1/4).

If she were to wrap gifts of the same size as stated, that means every gift will require the same measurement which is 1/4 of a yard. To find out how many gifts of the same size she can wrap before she uses up the entire roll, we solve as follows;

Total gifts = Total measurement/(1/4)

Total gifts = 20/(1/4)

Total gifts = 20 x 4/1

(When dividing with a fraction, the division sign turns into multiplication and the fraction is turned upside down, that is, 1/4 becomes 4/1)

Total gifts = 80

Therefore she can wrap 80 gifts of the same size from the entire roll

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
