Mai-li has 5 and start fraction 1 over 8 end fraction yd. of material. her new skirt will take 2 and three-fourths yd. how much material will she have left after the skirt is made? a. 2 and three-fourths yd. b. 3 and five-eighths yd. c. 2 and three-eighths yd. d. 3 and one-eighth yd.

Geometry ? i don't know how to do any of these.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
