Represent the unknows with n and d.
Then n+d = 44 (# of coins)
and
$0.05n + $0.10d = $3.10 (value of coins)
Solving the first equation for n, we get n = 44-d. Subst. 44-d for n in the 2nd equation:
0.05(44-d) + 0.10d = 3.10
Then 2.20 - 0.05d + 0.10d = 3.10, or
2.20 + 0.05d = 3.10, or 0.05d = 0.90. Solving for d,
0.90
d = -------- = 18
0.05
There are 18 dimes and 44-18 nickels. How many nickels is that? ;)
Answer:
Step-by-step explanation:
Some transformations for a function f(x) are shown below:
If , the function is translated up "k" units.
If , the function is translated down "k" units.
If , the function is reflected across the x-axis.
If , the function is reflected across the y-axis.
Therefore, knowing those transformations and given the exponential parent function:
If it is reflected across the y-axis and the it is translated down 4 units, we can determine that the resulting function is:
Answer:
The way to answer this question is to find out the price per pound potato by dividing the amount the restaurant chief paid by the number of pounds bought.
Your question lacks details on the pounds bought in the other stores so I will assume these figures and you can use it as a reference.
Restaurant B - 2 pounds
Restaurant C - 12 pounds
Restaurant D - 5 pounds
Price per pound
Restaurant A = 6.60/8
= $0.83
Restaurant B = 3.50/2
= $1.75
Restaurant C = 9.75/12
= $0.82
Restaurant D = 4.80/8
= $0.96
<u><em>Restaurant C </em></u><em>has the lowest price per pound for potatoes. </em>
F(3)=16 i saw this problem before so it should be the answer in the end
