42 students either ate pizza or chicken strips at lunch at a ratio of 2:5, how many kids ate pizza?

12 kids

Step-by-step explanation:

The answer is 12 kids because as 42 students ate pizza and chicken strips at a 2:5 ratio, we need to add 2+5=7, so 42 encounters 7 total parts. 42 divided by 7 equals 6, so 6 kids counter for each part. As pizza counters for 2 of the parts, 6x2=12 kids for pizza. Hope it helps!

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
