Answer:

Step-by-step explanation:

After creating an equilateral triangle using 3 toothpicks, I require 3 more toothpicks to create more 3 equilateral triangles ie.4 triangles it toto.

First place 3 toothpicks end to end on a Horizontal plane to create an equilateral triangle.

THEN erect 3 toothpicks on each corner of the triangles making other ends joined up together in space above the Horizontal plane so as to create another same THREE equilateral triangles. (I am unable to provide a pictorial presentation due to inadequacy of signs & symbols on the keyboard. )

I suppose, you must have visualised the superstructure.

Thanks.

Answer:

perimeter = 36

Step-by-step explanation:

Each diagonal side is the hypotenuse of a right triangle with legs of lengths 6 and 8.

c² = a² + b²

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = √100

c = 10

Each horizontal side measures 8.

perimeter = 8 + 8 + 10 + 10

perimeter = 36

The completed ratio chart is provided below:

Feet of Ribbon    1             5   10    15

Cost                     $0.60   $3  $6   $9

The amount Serena would get if she has $12 is 20 yards.

The amount Serena would pay if she wants 17 feet of the ribbon is $10.20.

The first step is to determine the unit cost of a ribbon.

Unit cost of a ribbon = $3 / 5 = $0.60

The cost of 10 feet of the ribbon = $0.60 x 10 = $6

The cost of 15 feet of the ribbon = $0.60 x 15 = $9

The feet of ribbon Serena can buy if she has $12 = $12 / $0.60 = 20 yards.

The cost of 17 feet of the ribbon = $0.60 x 17 = $10.20

Answer:

The Cardinality of this set {7,8,9} is n(P) = 8.

Step-by-step explanation:

Because:

n(P) = {{}, {7}, {8}, {9}, {7, 8}, {8, 9}, {7, 9}, {7, 8, 9}}

Hence by the formula 2^k.

where, k = number of elements in the set.

The cardinality is 8.

Hello, hope you are having a nice day.

This answer is not correct, because we can't add different variables. For instance, if we have 11x+2y, we can't add x's and y's together.

Therefore, the correct answer would be

11x+2y

Answer:

Step-by-step explanation:

The first step is the answer, so you would have gotten 100% if you just left the question there. The next step, the second step, is quite right.

If it was, then why didn't you do that in the first step?

Think of all the possibilities

60xy

10xy

12xy

10xy + 5y

12xy + 5x

There must be many more.

And yet dear one, you have only made 1 mistake. You combined xs and ys in step 2. Here's the rule.

Don't. If they were added, let them stay added. xs go with other xs. ys go with other ys. They never go together when they are added.
