Answer:
- 12x +9y ≥ 510
- y ≤ 2x
- y ≥ 25
Step-by-step explanation:
Phoebe earns 12x for her yard weeding, and Richie earns 9y for his dog walking. They want the sum of these earnings to be at least 510, so the first constraint inequality is ...
12x +9y ≥ 510
__
Richie plans to walk no more than 2x dogs, since y is the number of dogs he walks, the second constraint is ...
y ≤ 2x
__
Richie will walk at least 25 dogs, so ...
y ≥ 25
120 % = 160
---------------------------------------------------------------------------
Find 1 % :
---------------------------------------------------------------------------
120% = 160
1% = 160 ÷ 120
1% = 4/3
---------------------------------------------------------------------------
Find 100% :
---------------------------------------------------------------------------
1% = 4/3
100% = 4/3 x 100
100% = 133 1/3
---------------------------------------------------------------------------
Answer: 160 is 120% of 133 1/3

Answer:
Step-by-step explanation:
If you meant " | ", as in |x|, that's "absolute value." The domain of this function is "all real numbers," and the range is "all real numbers zero or greater."
To find the total amount, you will use the formula for finding compounded interest. This means you will be paid interest on top of the interest you have earned each year.
A = P(1 + r)^nt
P stands for the principal.
r is the interest rate when compounded annually
nt is the number of years
A = 17.50(1 + 0.04)^25
A = $46.65
This person would have $46.65 after 25 years.
