Step-by-step explanation:
The number of cups of red paint is always 15 of the total number of cups. 0.2 of the total number of cups.
She writes the equation r = 15t (r = 0.2t) to describe the relationship.
In this case, the total no. of cups is an independent variable. No. of cups do not depend on any term.
The number of cups of red paint is a dependent variable as it depends on the number of cups.
Is it a right triangle?? If so use the Pythagorean theorem (a2+b2=c2)
Take the amount of rows in the auditorium, 15, and multiply that by the number of new seats in each row, 3. You get 45. Now multiply the number of new seats, 45, by the cost of each seat, $74. You get $3,330.
A number - n
five times the number - 5n
nine more than five times the number - 5n+9
The answer is D.
Answer: 19.625 cm (Formula is 2πr)
Steps: 1.) 3.14 * 12.5 = 39.25
2.) 39.25 * 2 = 78.5
3.) 78.5 / 4 = 19.625 (using the 4 because the area is a fourth of a whole circle)
