Answer:

18

Step-by-step explanation:

So lets go voer what we know:

There are 6 pieces of ribbon.

Each piece of ribbon is 1 yard long.

We need 1/3 of each ribbon(1/3 yard).

To find this, lets take our 6 pieces of ribbbon, and break them into 3 seperate pieces.

This is because we need ribbons that are 1/3 of a yard. 3 ribbons would make up a single yard.

So:

The 6 yards of ribbon x 3 ribbons that make up 1 yard

6*3

=

18

I hope this makes more sense, and helps you understand better. I can try to explain in a different way if this still doesn't make sense.

I hope this helps! :)

Answer:

It’s D, 18 cuts

Step-by-step explanation:

She cut a 6 yard long ribbon into 1/3 yard pieces so you would have to divide to get the answer and the steps to dividing is

Stay the same, change the sign, flip it
so the 6 would stay the same, you would change the division sign to multiplication because division is the opposite of multiplication, and you would flip the 1/3 into 3/1 so

6 x 3/1 would be 18/1 which is just 18

Please help me for the brainliest answer
Oxana [17]

Answer:

aₙ= -2n²

Step-by-step explanation:

<h2><u>Solution 1:</u></h2>

The sequence:

  • -2, -8, -18, -32, -50

The difference between the terms:

  • -6, -10, -14, -18
  • a₁= -2
  • a₂= a₁ - 6 = a₁ - 2*3= a₁- 2*(2²-1)
  • a₃= a₂ - 10 = a₁ - 16= a₁ - 2*8= a₁ - 2*(3²-1)
  • a₄= a₃- 14= a₁ - 30= a₁ - 2*15= a₁ - 2*(4² -1)
  • ...
  • aₙ= a₁ -2*(n²-1)= -2 -2n² +2= -2n²

As per above, the nth term is: aₙ= -2n²

<h2><u /></h2><h2><u>Solution 2</u></h2>

The sequence:

  • -2, -8, -18, -32, -50
  • -2*1, -2*4, - 2*9, -2*25
  • -2*1², -2*2², -2*3², -2*4², -2*5², ..., -2*n²
  • aₙ= -2n²

The combined height of one fir tree and one pine tree is 212121 meters. The height of 444 fir trees stacked on top of each other
Drupady [299]

Answer:

Height of fir tree = 9 meters

height of pine tree= 12 meters

Step-by-step explanation:

The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.

Let x be the height of fir tree and y be the height of pine tree

x+y=21

Subtract x from both sides

y=21-x

height of 4 fir trees = pine tree +24

4x=y+24

Substitute 21-x or y in the above equation

4x=21-x+24

Add x on both sides

5x=45

Divide by 5 on both sides

x=9

Now plug in 9 for x and find out y

y=21-x

y=21-9

y=12

Height of fir tree = 9 meters

height of pine tree= 12 meters
