Answer:

They are different because multiplying whole numbers: you get a whole number ex: 3 x 7 = 21

Multiplying decimals: you get a whole and part of a whole ex: 12.39 x 2.5 = 30.975

Answer:

Multiplying decimals is very much like multiplying whole numbers - the major difference is that after you have finished multiplying all the terms (while ignoring the decimal points), you have to add up how many decimal places there are in the factors, and put that many decimal places in the answer.

Step-by-step explanation:

1.multiply by the number in the ones place

2.but a zero below in the ones place to holds its place

3.multiply the number in the tenths place

Two number cubes are rolled.

hichkok12 [17]

Answer:

When two number cubes are rolled,

Sample space= Total Possible outcome {11,22,33,44,55,66,12,21,13,31,14,41,15,51,16,61,23,32,24,42,25,52,26,62,34,43,35,53,36,63,45,54,46,64,56,65}=36

Probability of an event = \frac{\text{Total favorable outcome}}{\text{Total possible outcome}}

Sum of 4 is obtained when ={13,31,22}=3

Probability of getting 4 when 2 number cubes are rolled= \frac{3}{36}=\frac{1}{12}

Sum of the numbers is greater than 9= 10, 11,12={55,64,46,56,65,66}=6

Probability of getting(Sum of the numbers is greater than 9)=\frac{6}{36}=\frac{1}{6}

Since beta is in the first quadrant, the final answer will be positive.

To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that

$\sin( \beta ) = \frac{ \sqrt{17} }{5}$

So, this means that

$\sin( \frac{ \beta }{2} ) = \sqrt{ \frac{1 - \frac{ \sqrt{17} }{2} }{2} } = \sqrt{ \frac{2 - \sqrt{17} }{4} } = \frac{ \sqrt{2 - \sqrt{17} } }{2}$
