A cup of hot coffee has been left to cool in a room with an ambient temperature of 21°C.
The relationship between the elapsed time, m, in minutes, since the coffee was left to cool, and the
temperature of the coffee, T, measured in °C. is modeled by the following function.
T(m) = 21 + 74.10 0.03m
What will the temperature of the coffee be after 10 minutes?
Round your answer, if necessary, to the nearest hundredth.

Arestaurant needs to buy thirty-seven new plates. if each box has five plates in it, how many boxes will they need to buy?

Which statements about these triangles is true

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
