To prepare for a bake-off, Sarah used 0.68 kilogram of flour each day for 2 weeks. How many grams did Sarah use in those 2 weeks? 1 kg = 1,000 g

Sarah used 9520 grams of flour in 2 weeks

Step-by-step explanation:

1. Sarah used 0.68 kilograms daily for two weeks. Two weeks is 14 days. multiply 0.68 kilograms by the amount of days (14) = 9.52 kilograms

2. convert kilograms into grams by multiplying by 1000

9.52kg×1000=9520g

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
