U decreased by 17 is u-17.
if you decrease a number from something, you use subtraction.
therefore, u decreased by 17 is u-17
There are two scales that may be possible for this scale model; one where it's for every foot and one where it's for every meter.
The for every foot would be better to find out since the scale would be easier to use.
First, you have to divide each sided by 4.2, since you want to find how many meters for each foot.
![4.2 \div 4.2 = 1 \\ 525 \div 4.2 = 125](https://tex.z-dn.net/?f=4.2%20%5Cdiv%204.2%20%3D%201%20%5C%5C%20525%20%5Cdiv%204.2%20%3D%20125)
For every 1 foot used in the model, the actual will be 125 meters.
1 ft = 125 m
Answer:
x=(log(5/4))/(log(4))
Step-by-step explanation:
Answer: 12 red balls must be added
Step-by-step explanation:
Starting out with 15 balls, 6 red implies 9 blue. If blue remains 9, then we expect red to be 18 for a probability at 2/3. 18-6 = 12
