Madison is preheating her oven before using it to bake. The initial temperature of the oven is 75° and the temperature will increase at a rate of 15° per minute after being turned on. What is the temperature of the oven 19 minutes after being turned on? What is the temperature of the oven tt minutes after being turned on?

i think it would be 42cm

im not sure what this means: mc011-7.jpg

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

hi there, i would be interested to you with your test, may you add the questions and answer options.
