<u>Answer: </u>

The pattern for hats is \frac{n}{1.5} and the pattern for scarves is n\times 1.5 ; where n is the no. of hat or scarf respectively

<u>Explanation:</u>

Let, cost of hat and scarves be x and y respectively

Then, according to question,

y (cost of scarves) = 1.5 \times  x (cost of hats)

or,x =\frac{y}{1.5}

Calculating for hats,

For 1 hat; putting y = 1         x = \frac{1}{1.5}

For 2 hats; putting y = 2   x = \frac{2}{1.5}

For 3 hats; putting y = 3   x = \frac{3}{1.5}

For 4 hats; putting y = 4           x = \frac{4}{1.5}

For 5 hats; putting y = 5   x = \frac{5}{1.5}

Therefore, we can see the pattern for hats is \frac{n}{1.5}, where n is no. of hats

Calculating for scarves,

For 1 scarves; putting x = 1   x = 1\times 1.5= 1.5

For 2 scarves; putting x = 2   x = 2\times 1.5= = 3.0

For 3 scarves; putting x = 3   x = 3\times 1.5= = 4.5

For 4 scarves; putting x = 4   x = 4\times 1.5= = 6.0

For 5 scarves; putting x = 5   x = 5\times 1.5= = 7.5

Therefore, we can see the pattern for scarves isn\times 1.5, where n is no. of scarves

if the kinetic energy of an aeroplane moving at a velocity of 100m/s is 200j ,what is the mass of the aeroplane
Black_prince [1.1K]

Answer:

<u>0.04kg</u>

Step-by-step explanation:

Kinetic energy Formula: eK=0.5×m×v²

to work out mass

we can rearrange the formula and make it:

~m=eK÷(0.5×v²)

now insert the missing digits into the formula:

m=200÷(0.5×100²)

work it out, and you get your answer

m=0.04kg

Hopefully this helped-have a good day)
