Reflexive pretty much means something relating to itself. The reflexive property of equality simply states that a value is equal to itself. Further, this property states that for all real numbers, so your answer will be (A) x = x.

Assume that an average cell has a diameter of

emmasim [6.3K]

Given that the volume of a cell is 50 cubic micrometers. It says to find the number of cells present in 1 cubic centimeter.

So we need to first convert the units of volume of a cell, then we can find the total number of cells in 1 cubic centimeter.

We know 1 meter = 100 centimeters = 1000000 micrometers

So 1 centimeter = 10000 micrometers

Taking Cubic powers on both sides :-

1 cubic centimeters = 10¹² cubic micrometers

1 cubic micrometers = 10⁻¹² cubic centimeters

50 cubic micrometers = 50 × 10⁻¹² = 5 × 10⁻¹¹ cubic centimeters

So volume of one cell = 5 × 10⁻¹¹ cubic centimeters

Number of cells = $\frac{Total\;\; volume}{Volume\;\; of\;\; one\;\; cell} = \frac{1\;cm^{3}}{5 * 10^{-11}\;cm^{3}} = \frac{10^{11}}{5}$ = 2 × 10¹⁰ cells.

So, total number of cells = 2 × 10¹⁰ cells.

This table shows the relationship of the total number of pieces of fruit to the number of bananas.

ddd [48]

Given:

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.

To find:

Why is $\dfrac{6}{5}$ not equivalent to $\dfrac{3}{2}$ .

Solution:

If a, b, c are real numbers, then

$\dfrac{a}{b}=\dfrac{a\times c}{b\times c}$

The given fraction is $\dfrac{3}{2}$ . It can be written as:

$\dfrac{3\times 2}{2\times 2}=\dfrac{6}{4}$

The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be $\dfrac{6}{4}$ , not $\dfrac{6}{5}$ .

Therefore, the correct option is A.

142/80 into mixed number

Cerrena [4.2K]

80 goes into 142 once, so one is our whole number. there are still 62 / 80 left, so we reduce this fraction. The answer is 1 $\frac{31}{40}$
