Up to this point, the only types of numbers you've seen have been rational numbers. You can write any rational number as a fract

ion. The prefix ir- means not. What do you think it means for a number to be irrational? Can you think of any numbers that are irrational?

Answer:

since 'rational' numbers can be written as a ratio, such as a/b, then 'irrational' numbers cannot be written that way.

Step-by-step explanation:

since 'rational' numbers can be written as a ratio, such as a/b, then 'irrational' numbers cannot be written that way.

Square roots of non-perfect squares are irrational numbers because they are non-terminating, non-repeating decimals.

Jeff is baking a cake. The recipe says that he has to mix 32 grams of vanilla powder to the flour.
sergeinik [125]

If 1 cup of that particular vanilla powder has a mass of 128 grams, then \dfrac{2}{3} of a cup of vanilla powder has a mass of

\dfrac{2}{3} \cdot 128=\dfrac{256}{3}=85\dfrac{1}{3} grams.

Since

85\dfrac{1}{3}-32=53\dfrac{1}{3} grams and \dfrac{5}{12} of a cup of vanilla powder is

\dfrac{5}{12}\cdot 128=\dfrac{5\cdot 128}{12}=\dfrac{5\cdot 32}{3}=\dfrac{160}{3}=53\dfrac{1}{3},

then correct answer is that he went over by  \dfrac{5}{12}  of a cup.

Answer: correct choice is B.

Find the geometric mean of the pair of numbers
Svetach [21]

Answer: a. 55

Step-by-step explanation:

The formula to find the geometeric mean between two numbers a and b is given by :-

G.M. =\sqrt{ab}

The given numbers are : 275 and 11

The geometric mean of 275 and 11 is given by :-

G.M.=\sqrt{275\times11}\\\\\Rightarrow\ G.M. =\sqrt{3025}\\\\\Rightarrow\ G.M.=\sqrt{55\times55}\\\\\Rightarrow\ G.M.=\sqrt{55^2}\\\\\Rightarrow\ G.M.=55

Hence, the geometric mean of 275 and 11 is 55.

So , the correct option is a. 55 .
