A cheese maker changes the temperature of his milk at a rate of -3°F per minute. What is the change in the temperature of the milk after 15 minutes?

-45°

Step-by-step explanation: This is because if it changes -3°F every minute and there are 15 minutes, just do 15*-3. In this case, is -45°

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
