Answer:

58 in

Step-by-step explanation:

38 divided by 19 = 2

20 divided by 2 = 10

19 x 2 = 38

10 x 2 =20

38 + 20 = 58

The area of the dining room at Thomas Jefferson so I'm in Monticello is about 342 ft.² is the approximate length of one side is
Nat2105 [25]

Answer:

Yes, the approximate length of one side is a prime number less than 25.

The approximate dimensions of the room are 19 ft by 18 ft.

Step-by-step explanation:

Assuming the dining room is rectangular in shape

Approximate area of the dining room = 342 ft^2

The area of a rectangle is calculated by multiplying the length of the rectangle by the width.

Assuming the approximate length is a prime number less than 25

The closest prime number to 25 is 19

Approximate length = 19 ft

Approximate width = approximate area ÷ approximate length = 342 ft^2 ÷ 19 ft = 18 ft

Approximate dimensions of the room = 19 ft by 18 ft

If A ⊂ B, then A ∩ B = A ∪ B. always sometimes or never
Lisa [10]

Sometimes. Proof:

Assume A\subset B.

Let a\in A\cap B, so that a\in A and a\in B. Then of course a\in A\cup B, so A\cap B\subseteq A\cup B.

Now let a\in A\cup B, so that a\in A *or* a\in B. Since A\subset B, if a\in A then a\in B, so that a\in A\cap B. But if a\in B, then a\not\in A, so it's not always the case that a\in A\cap B, and therefore in general A\cup B\not\subseteq A\cap B.

Solve the system by substitution  y=-382<br> y = 6x + 3<br> 
nikdorinn [45]

okay so i assume you meant these two:

y=-382 and y=6x+3

Answer:

y=-382

x=-385/6

Step By Step:

y=−382;y=6x+3

Step: Solve y=−382 for y:

y=−382

Step: Substitute −382 for y in y=6x+3:

y=6x+3

−382=6x+3

−382+−6x=6x+3+−6x (Add -6x to both sides)

−6x−382=3

−6x−382+382=3+382 (Add 382 to both sides)

−6x=385

Divide both sides by -6.

x=-385/6

y=-382

a student needs to fill a tank with 9 liters of waters how many 1/3 liters of water will it take to fill the tank
laiz [17]

It will take 27 containers of 1/3 liter to fill the tank.

Since you need 3 containers of 1/3 to have a full liter, and 9 liters for the tank, 9*3=27.
