Write a conditional statement that the Venn Diagram illustrates.
Margaret [11]
<h2>Answer :</h2>

\bf \implies{Set  \: of  \: squares  \:  \leqslant\:  Set  \: of}\bf{ quadrilaterals}

<h2>Step-by-step explanation :</h2>

As we know, that all squares are quadrilateral but its converse is not necessarily true.

\therefore Set of Quadrilaterals is a super set of set of squares.

i.e. set of squares ≤ set of quadrilaterals.

From the picture, we can know that quadrilaterals consists of all the squares and square is a type of quadrilateral. All the squares belong to quadrilaterals, while not all the quadrilaterals belong to squares.

[It's important to have a good understanding of venn diagram as it illustrates the connection between things in it]

If you multiplied the mystery number by 1000, the resulting number would have a 7 in the ones place.
ser-zykov [4K]

The answer rounded to the nearest hundredth is 84.65.

Consider the number 84.647.

If we multiply this number by 1000, the result is 84647 which has 7 in its one's place.

Also, note that the value of the digit in the ones place is 4, which is half of 8, the value in the tenths place.

The remaining digit in the tenths place is 4.

Hence, the correct answer is 84.65 rounded to the nearest nundredth.

svetlana [45]

Well you have to do PEMDAS

So we have an exponent so that will turn into a positive X

X+4x=10

So now we combine our X's together to get 5X=10

Now we divide both sides by X which gives us 2

Sorry read the problem wrong

To write this as the image, we simply have to add a mark on the A

This mark is at the upper right

We have it as A’ (x,y)
