Answer:

N = D * 1.20

Step-by-step explanation:

In order to calculate the number of dishes that the previous menu had we first need to turn this percentage into a decimal by dividing it by 100

20% / 100 = 0.20

Now we add a 1 to it since we are increasing the old menu by this amount

0.20 + 1 = 1.20

Now we can multiply this by the previous menu dishes (D) to get the new amount of menu dishes (N)

N = D * 1.20

<h3>Answer:   (n-1)^2</h3>

This is because we have a list of perfect squares 0,1,4,9,...

We use n-1 in place of n because we're shifting things one spot to the left, since we start at 0 instead of 1.

In other words, if the answer was n^2, then the first term would be 1^2 = 1, the second term would be 2^2 = 4, and so on. But again, we started with 0^2 = 0, so that's why we need the n-1 shift.

You can confirm this is the case by plugging n = 1 into (n-1)^2 and you should find the result is 0^2 = 0. Similarly, if you tried n = 2, you should get 1^2 = 1, and so on. It appears you already wrote the answer when you wrote "Mark Scheme".

All of this only applies to sequence A.

side note: n is some positive whole number.

If the mass of a material is 44 grams and the volume of the material is 6 cm^3, what would the density of the material be?
Svetlanka [38]

Density is mass per unit volume.

For the given material that has a mass of 44 grams occupying a volume of 6 cm^3, we divide the mass by the volume, i.e.

density of material = 44 grams / 6 cm^3 = 44/6 grams/cm^3 = 7.3 g/cm^3 (to two significant figures)

Can someone with knowledge see what I did wrong on number 4<br>also see if number 3 is right​
Yakvenalex [24]

Answer:

#4.  m=0;

#3.  m = \frac{-1}{2}

Step-by-step explanation:

It seems right.

#4.  

Maybe your teacher wants you to write m=0; because when a fraction has a numerator equal to zero then the fraction is zero.

#3.

Maybe your teachers want you to simplify the fraction and write m = \frac{-1}{2}

Is 4 to 7 the same as 7 to 4? Explain why or why not.
Julli [10]
Yes because 4 to 7 is the same as 7 x 4 which equals 28. 7 to 4 is the same as 7 x 4 which also equals 28.
