If set D is not the empty set but is a subset of set E, then which of the following is true? D ∩ E = D D ∩ E = E D ∩ E = ∅

Answers

Answer 1

Answer:

Answer:

$D\cap E$ =D

Step-by-step explanation:

We are given that D is not empty set but D is a subset of set E.

We have to find the true statement.

$D\neq \phi$

D is a subset of set E

Therefore, $D\subset E\neq \phi$

Intersection: It is the set of common elements of two sets.

Therefore, $D\cap E$ =D

Because E contains all elements of D .

Hence, Option A is true.

Answer 2

Answer:

Answer:

D intersect E=D (the first one you have)

Step-by-step explanation:

D is a subset of E

That means all the elements in D are also in E

So the intersection of D and E is D.

The first thing you wrote is correct, that is, D intersect E=D is right

Ms.stoner purchased computer for 1,150. If the sales tax is 7.5 what is the total purchase?

Answers

Answer:

$1,236.25‬

Step-by-step explanation:

Since sales tax is 7.5% of the purchase, and since the pc costs 1,150, take 7.5% of 1,150, and add 1,150 and the new value together.

7.5 / 100 = 0.075

1150 * 0.075 = 86.25

1150 + 86.25 = 1236.25

1/2 = 2/4

We know that these are equal because:-

1*2 = 2
2*2 = 4

2/4 = 1/2

If a rectangle has a length of x + 2, a width of 7, and a perimeter of 32.what is the vaule of X

explain how u got the answer

Answers

you need to write the Eqation like so: 2(X + 2 + 7) = 32 then divide 32 by 2 = 16 then all you have left is X + 2 + 7 = 16 then add 2 and 7 together which wili give you this X + 9 = 16 then you subtract 9 from 16 which leaves X alone. And the answer would be 7
