To decorate a cake, you make a shade of green icing using 3 drops of yellow food coloring for every 4 drops of blue. if you use 12 drops of yellow food coloring, how many drops of blue food coloring would you need?

You would need 16 because 3 × 4 = 12 and you need to do the same to the blue so you would do the equation 4 × 4 = ? which is 16.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
