There are 20 students in a math class who have brown hair. This represents 80 percent of the students in the class. Which equation can be used to find the total number of students in the math class? StartFraction 20 times 100 Over 80 times 100 EndFraction = StartFraction 2000 Over 8000 EndFraction StartFraction 80 times 5 Over 20 times 5 EndFraction = StartFraction 400 Over 100 EndFraction StartFraction 80 divided by 4 Over 100 divided by 4 EndFraction = StartFraction 20 Over 25 EndFraction StartFraction 20 divided by 1 Over 80 divided by 1 EndFraction = StartFraction 20 Over 80 EndFraction

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
