Theluner calender would be inaccurate because it doesnt shouw the full 29 and a half days as the moon turns through its phases

Step-by-step explanation:

Consider that one cycle of the moon phases would be considered as one month. This would mean that in 29 months one month would be over. The 1/2 would not be considered as one day. So, at the end of 12 months the 1/2 days would add up and you would end up with 12×1/2 = 6 extra days.

In the gregorian calender the revoultion around the sun is considered as the year which takes 365.25 days. The months are arranged according to 31 or 30 days. However at the end of 4 years we get one whole day. Hence, the leap has 366 days.

Answer:

So it will take 6 minutes to ring up 72 items.

Step-by-step explanation:

Well this seems pretty simple just have to reads the question and know what to find.

So what we know :

A cashier can ring up 12 items per minute

So :

1 minute = 12 Minutes

And we have to find :

How long for 72 items

So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.

So :

72 / 12

So it will take 6 minutes to ring up 72 items.

I hope this helps!

Answer:

315

Step-by-step explanation:

1. This is not a scale rectangle and it angers me.

2. All you have to do is draw proportions.

15x21=315

Youll notice that 5x3=15 and 7x3=21 so it’s just proportions!

$2\cdot3\sqer2\cdot2(5+\sqrt2)=(2\cdot3\cdot2)\sqrt2(5+\sqrt2)=12\sqrt2(5+\sqrt2)\\\\=60\sqrt2+12\sqrt{2^2}=60\sqrt2+12\cdot2=60\sqrt2+24$

5m + 3 ( 8m +7 ) +4^2 Can someone help me

Pie

Answer:

29m+37?

Step-by-step explanation:

Pemdas

5m+3(8m+7)+4^2

Parentheses first: 5m+24m+21+4^2

Exponents next: 5m+24m+21+16

No multiplication or division so addition is last:

29m+37

These two can't add together because one has a variable.
