Which of the following temperatures is most precise? a.250 degrees b.98.6 degrees c.57 degrees d.100 degrees

B.98.6

Step-by-step explanation:

A.250 degrees   This has 2 significant figures.  The last 0 is not significant

B.98.6 degrees   This has 3 significant figures

C.57 degrees   This has 2 significant figures

D.100 degrees  This has 1 significant figures

The more significant figures, the more precise

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
