Write a decimal that is equivalent to three and ten hundredths.

The decimal equivalent to three and ten hundredths is 3.1

1 hundredth = 1/100 = 0.01

10 hundredth = 10/100 = 0.1

Therefore,

three and ten hundredths

= 3 + 0.1

= 3.1

The number in decimal expression is:

3.1

Step-by-step explanation:

We have to write the given number in a decimal expression.

The information about the number is given as:

three and ten hundredths.

Hence, in decimals the number is written as:

3.1

( since , three is to be written before the decimal point

as 3 is 3.0

and the number 10 is to be written after the decimal .

since, 10/100=0.1)

Hence, the number in decimal expression is:

3.1

2

step-by-2step 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.
