Penelope eats 4 chocolates per day, because in one day, 20 chocolates are in the box. Then, after 2 more days, 8 chocolates are eaten. That means, if she eats an even amount of chocolates, she eats 4 chocolates per day. To check this pattern, on the fourth day, there are 8 chocolates left. 12 - 8 = 4, and the pattern would continue. On the fifth day, 4 chocolates would be left, and on the sixth day, 0 chocolates would be left.

Answer:

Step-by-step explanation:

1)a ) Let the constant proportionality =k

Direct proportion.So, y = kx

Plugin y = 6 and x =2 and find k

6 = k*2

6/2 = k

k = 3

Constant proportionality = 3

b) y = 3x

When x = 7 ; y = 3*7 = 21

y = 21

c)When x = 9,

y = 3*9

y = 27

d) When y = 9,

9 = 3*x

9/3 = x

x = 3

e)when y = 30

30 = 3*x

30/3 =x

x = 10

3) y is inversely proportion to x³

$y =k\dfrac{1}{x^{3}}\\\\3 =k *\dfrac{1}{2^{3}}\\\\3=k*\dfrac{1}{8}\\\\3*8=k\\\\24 = k$

b) when x = 4

$y=24*\dfrac{1}{4*4*4}\\\\y=\dfrac{3}{8}$

c) When x = 6

$y = 24*\dfrac{1}{6*6*6}\\\\y=\dfrac{1}{9}$

d) When y = 24

$24= 24*\dfrac{1}{x^{3}}\\\\x^{3}*24=24\\\\x^{3}=\dfrac{24}{24}\\\\x^{3}=1\\\\x = 1$

Which property justifies this r(s + t) = rs + rt<br> statement

Law Incorporation [45]

R(s+t) = rs + rt represents Distributive Property because r is multiplying s and t
i.e. ( r*s + r*t )
= rs + rt

So correct answer is Distributive Property.

hope this helps :)

What number should be at pyramid

ValentinkaMS [17]

$\tt Step-by-step~explanation:$

To solve, we have to look for a pattern.

$\tt Step~1:$

When you see pyramids like these, they usually tell you to add/multiply the two numbers to get a third number that goes on top. Here, we can see 3 and 4 on the bottom left hand corner. The third number on top of both 3 and 4 is 7. 3 + 4 = 7. Let's check 4 and 5, the middle two numbers. 4 + 5 = 9, and that number is on top of 4 and 5. Therefore, we can confirm that this is an addition pyramid.

$\tt Step~2:$
