Which number set has only irrational numbers? a) {-7.4, 0, 3.14} b) { 8 , 9 , 10 } c) {- 5 6 , 7 8 , π 2 } d) { 2 , 5 , π}

I think is it D too.

Step-by-step explanation:

Solve the fractions, and you will see.

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
