Each strip is 29 cm
------------------------------------------------------
Change the m to cm
------------------------------------------------------
6 m = 600 cm
------------------------------------------------------
Find the number of strips for 1 6m-board
------------------------------------------------------
Find the number of strips that can be cut from the 6m board.
600 ÷ 29 = 20 pieces remainder 20cm
So we can only cut 20 pieces of 29 strips from one 6m board.
------------------------------------------------------
Find number of boards needed
------------------------------------------------------
70 ÷ 20 = 3.5
We need 3.5 of the 6m boards.
Since she can't have half a board, she has to buy 4 pieces of the board.
------------------------------------------------------
Answer: 4 pieces of the 6m board.

Answer:
can u be more specific so i can properly help u
Explanation:
pls explain and i will edit my answer
Recall that the direction of a vector can be seen from its slope, namely b/a.
let's take a peek at a couple of vectors, and multiply them by a scalar of 2.
hmmm say < 3 , 7 > , it has a slope of 7/3, now if we use a scalar of 2
2<3,7> => < 6 , 14 >, now, the slope of that is 14/6 which simplifies to, yeap, you guessed it, to 7/3, no change in the slope.
and say hmmmm < 11 , -2 >, slope of -2/11, let's multiply it by 2
2<11,-2> => <22 , -4 >, slope is -4/22 which simplifies to -2/11.
so, the vector's magnitude gets blown up, but the slope remains the same.
Answer: 21
Step-by-step explanation:
Ok so first of all the numbers in the parentheses go first.
So 6 to the power of 2 (6^2) would be 6x6 which equals 36
50-36=14
After that you just keep rewriting the problem after every step.
Since the 3 is outside of the parentheses, you would multiply it with the 14
3x14=42
Finally 42÷ 2=21
3x (50 - 6^2) ÷ 2 =
3(14)÷ 2
42÷ 2= <u><em>21</em></u>

<u><em>Hope this helps (:</em></u>
<u><em>Btw sorry if it's a bit confusing but the answer is 21</em></u>
