Answer:
12 eggs
Step-by-step explanation:
Number of eggs Ming needed to make 30 cookies = 3 eggs
We need to find how many eggs does he need to make 120 cookies. We can solve this problem by unity method i.e. find the quantity of egg needed for 1 cookie and then multiplying it by 120 to get the number of eggs needed for 120 cookies.
Number of eggs Ming needed to make 30 cookies = 3 eggs
Dividing both sides by 30, we can write:
Number of eggs Ming needed to make 1 cookie = eggs
Multiplying both sides by 120, we can write:
Number of eggs Ming needed to make 120 cookies = eggs
This means, Ming needs 12 eggs to make 120 cookies according to his recipe.
Answer:
288 possible seating arrangements.
Step-by-step explanation:
There are 4 possible choices for the first seat.
There are 3 possible choice for the sixth seat.
There are 4 possible choices for the second seat.
There are 3 possible choices for the third seat.
There are 2 possible choices for the fourth seat
There is only 1 possible choices for the fifth seat.
4×3×4×3×2×1=
12×4×3×2×1=
48×3×2×1=
144×2×1=
288×1=
288 possible seating arrangements.
The area depends on whether the 8dm path runs top to bottom or left to right
the followin solution will be for left to right
we need to draw a picture (see first attachment)
to simplify it, we can push the paths to the side (see second attachment)
now we can easily see that the usable area is the part not used by the paths
the width is 20-0.7=19.3
the height is 30-0.8=29.2
area=19.3*29.2=563.56 square meters
if it was frmo top to bottom
20-0.8=19.2
30-0.7=29.3
19.2*29.3=562.56 square meters
if the path is like in the attachments, then the usable area is 563.56 square meters
if the 7dm path and the 8dm path are switched, then the usable area is 562.56 square meters

Answer: 2160
Step-by-step explanation:
Given : At a computer store, a customer is considering 10 different computers, 6 different monitors, 9 different printers and 4 different scanners.
We assume that each of the components is compatible with one another and that one of each is to be selected.
then by Fundamental counting principle , the number of different computer systems possible is given by :-
Hence, the number of different computer systems possible= 2160
- The Fundamental Counting Principle is a technique in Mathematics to calculate the number of possible outcomes by multiplying the events together .
