The student that did more maths problems per minute is Diedra.
In order to determine which student did more maths problems per minute, the rate of each student has to be determined. Rate is the total questions solved divided by the time.
Rate = total questions / total time
Malcolm = 15 / 18 = 0.833 problems per minute
Diedra = 16/ 17 = 0.941 problems per minute

421 would be the missing number.

Answer:
48a^2b^6c^5d^2
Step-by-step explanation:
Multiply whole numbers and add exponents.
Okay so the formula for this is going to be 1/2*base*height. The * means multiply.
so to do it easily lets start with the whole numbers.
15*9=135
so we take that and divide it by two because that it the same as multiplying by 1/2
135/2=The area will be 67.5!!!
Hope this helps you
