Jack = 3 presents every 15 minutes
luke = 4 presents every 20 minutes
target = 20 presents wrapped per person
y = kx ; where k is the constant rate, x is the number of presents wrapped, y is the total number of minutes spent wrapping x number of presents.
we need to compute for the unit rate of each individual.
Jack: 15 minutes / 3 presents = 5 minutes per present
Luke: 20 minutes / 5 presents = 4 minutes per present
Jack:
y = 5 minutes per present * 20 presents = 100 minutes
Luke:
y = 4 minutes per present * 20 presents = 80 minutes
The answer is 8.2 ^2 ......
The answer is: 8 red marbles!
This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x
We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8
If this helped, give me brainliest :)
14.14 inches
Convert 135° into radians. 135*2pi/360=3pi/4.
6*3pi/4=18pi/4=9pi/2=14.14
Another viable method is to do 2pi*6*135/360=14.14
The answer is 22.666666667
