Answer:
The home printer is faster.
Step-by-step explanation:
25 photos in 12.5 minutes
12.5 is half of 25 and therefore this is a two to one ratio.
So 2 photos print in 1 minute with the office printer.
And 4 photos in 2 minutes(this is relevant later)
The home printer prints 15 photos in 6 minutes. Since 15 is not divisible by 6 without a remainder divide both by 3.
So 5 photos in 2 minutes. This is faster than the office printer.
To find how many photos it would print in 12 more minutes, simply multiply 15 by two, since the minutes(6) was multiplied by 2 to get 12. This leaves you with an answer of 30 photos in 12 minutes
Answer:
The greatest number of groups he could have made is 4 groups
Each of the four groups will have:
4 Squares each
7 circles each
Step-by-step explanation:
16 squares
28 circles
Find the highest common factor of 16 and 28
16: 1, 2, 4, 8, 16
28: 1, 2, 3, 4, 7, 14, 28
The highest common factor of 16 and 28 is 4
This means the greatest number of groups he could have made is 4 groups
Each of the four groups will have:
16 squares = 16 / 4
= 4 Squares each
28 circles = 28 / 4
= 7 circles each
Each of the four groups will have:
4 Squares each
7 circles each
New perimeter will be equal = old perimeter*3=36*3=108
