Penny is training for a race. First she ran 1/10 of a mile 4 times. Next she ran 1/5 of a mile 3 times. Then she ran3/10 of a mile 2 times. How far did penny run during her training? is it one and 3/5 mile?

1/10 mile = 4 times

1/5 mile = 3 times

3/10 mile = 2 times

Thus total distance covered by her;

4(1/10) + 3(1/5) + 2(3/10)

2(1/5) + 3(1/5) + 1(3/5)

2/5 + 3/5 + 3/5

8/5 or 1.6 miles

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )

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.
