Answer: (2a+2b,2c)
the first one
Step-by-step explanation:
you can add or subtract letter such as *a or *b so you "add" them which is 2a+2b and "y" for point B is 2c so it stays the same
sorry i such at explaining
Answer:
The relationship B is different than the other three, because it has a different proportionality constant.
Step-by-step explanation:
All available options show direct relationships, which are defined as follows:
(1)
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Proportionality constant, dimensionless.
We proceed to use the following strategy based on the proportionality constant, that is:
A different relationship must indicate a different proportionality constant:
Option A (
, 
)
Option B (
, 
)
Option C (
, 
)
Option D (, 
)
The relationship B is different than the other three, because it has a different proportionality constant.
Figure A has the largest shaded figure because the 4 parts that aren’t covered are less than the other multiple parts of other figures.
Answer:
2/3
Step-by-step explanation:
I think it is 2/3 because 20 is the probability and 30 are the users. So basically, it is the probability over the total in this case 30. 20/30=2/3. Hope it helps?
To answer this you could do a couple things. 1. Actually calculate both tips and then subtract them. Here is the math ( assuming it is $60, not 60% that you mean). a. 0.15 x 60 = $9. b. 0.0825 x 2 x 60=$9.90. c. 9.90-9.00= $0.90 difference.
The other strategy would be to find the difference on the percents and then multiply by $60. a. 8.25%x2=16.5%-15%. Difference of 1.5%. b. 0.015 x $60=$0.90.
