A -

By saying SQRT(50) = (2) X SQRT(25) is wrong because

(2) X SQRT(25) = SQRT(4) X SQRT(25)
= SQRT (100)

B -

To estimate the square room of 50, we have to break 50 into multiples like 1 X 50, 2X25
The ideal multiple should consist at least one integer that can be square root into an integer. Now, let’s start with the multiples of 50.

1 X 50, 2 X 25, 5 X 10,

The most deal multiple is 2 X 25 as it contains an integer 25, that can be squareroot into another integer.
Hence, it will be
SQRT(2) X SQRT(25) =
SQRT (2) X 5 = (1.41) X 5 = 7.05

Answer:

aprox 7.1

Step-by-step explanation:

A - it is wrong because he is using wrongly the properties of radicals. He is, nevertheless, using a good intuition.

B

\sqrt[]{50} = \sqrt[]{2\cdot 25} = \sqrt[]{2}\cdot \sqrt[]{25} = 5\sqrt[]{2}

So, since \sqrt[]{2} = 1.41 (aproximately), then

\sqrt[]{50} = 5\cdot 1.41 = 7.07 which is 7.1 when rounded.

kotegsom [21]

The incorrect rounding for 53.864 is 53.87

<h3>How to approximation a decimal?</h3>

The decimal to be approximated is as follows;

53.864

The first option rounded the decimal to 2 significant figures or a whole number.

The second option is incorrect because they rounded it wrongly to 2 decimal places. The correct 2 decimal round is 53.86.

The third option is approximated rightly to one decimal place.

The last option is rounded to the closes tens term.

name the lengths of the sides of three rectangles with a perimeter of 12 units use only whole numbers
AysviL [449]
The perimeter of a rectangle is 2(w+l)
We can find the lengths by setting the equation equal to 12.
12=2(w+l)
12÷2=(2(w+l))÷2
6=w+l
6=1+5
6=2+4
6=3+3
These are the lengths of the sides of three rectangles with a perimeter of 12 units.
You're probably wondering why the third one has two of the same number, because that's usually how the lengths of sides of squares are, not rectangles.
Well, there's this wonderful thing about the rules of shapes.
<em>Squares ARE rectangles.
</em>Because they follow the rules for a rectangle, squares are also classified as rectangles.
So, the rectangle side lengths are as follows:
1 unit by 5 units
2 units by 4 units
3 units by 3 units

Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate. monthly temperature
Svetach [21]

Answer:

Interval level of measurement

Step-by-step explanation:

There are four level of measurements; nominal, ordinal, interval and ratio.

Nominal level of measurements separates data into exclusive categories. There is no ranking or order required in the data. Temperature is not divided into categories.

Ordinal level of measurements separates data into exclusive categories like nominal but there is ranking and order required for the data. Temperature doe not require categories or ranking.

Interval level of measurement ranks data where there are differences between units of measure but there is no meaningful zero. For temperature, a zero is not required and the interval between values is interpret-able. For example, the distance between 67 to 67 is the same as distance between 67 to 71, 71 to 75 and 75 to 79 degree f.
