3. Three art students used a total of 28 - inches of string for an art project. 늘 Each student used 2 1 1 2 inches of string plus an additional 13 inches of string for each day they worked on the art project. Each student worked on the project the same number of days. Which equation could be used to find d, the number of days the students worked on the art project? 4 А 28 B 28 28- +1 28.1 = 3(234) + C D. 28 +

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
