Answer:

3 .1 /2 = 3.50 = 350 %

Step-by-step explanation:

To convert a fraction into decimal, one needs to transform it so that the fraction is a sum of fractions each or which has a denominator, which is a power of  10.

3 .1/ 2 =  3 1 × 50 /2 × 50  =  3 .50 /100  = 3.50

And for conversion to percentage, one needs to multiply this by  

100

Hence  

3 .1/ 2 =  3.50  =  ( 3.50 × 100 )%  =  350 %

hope it helps!

To find:

The expanded form and find the sum.

Solution:

We have,

\sum _{k=4}^9(5k+3)

The expanded form of given sum is:

\sum _{k=4}^9(5k+3)=(5(4)+3)+(5(5)+3)+(5(6)+3)+(5(7)+3)+(5(8)+3)+(5(9)+3)

\sum _{k=4}^9(5k+3)=(20+3)+(25+3)+(30+3)+(35+3)+(4+3)+(45+3)

\sum _{k=4}^9(5k+3)=23+28+33+38+43+48

\sum _{k=4}^9(5k+3)=213

Therefore, the correct option is C.

Which problem is solved using this model? 15÷15   3÷115    3÷15  15÷15   https://static.k12.com/nextgen_media/assets/1503272-MAT
Pie

Answer:

As the model is shown below.

As per model a thing is divided into five parts.There are three things and each one of them is being divided into five equal parts.

The value of fifth part of each of them is 1/5.

If we consider each part of a thing as one,

So, total number of parts = 15

Total thing=3

So, the answer of the above model is 3÷ 15.

Out of all the options which are 15÷15  , 3÷115 ,   3÷15,  15÷15  →3÷15 is correct.
