Answer:
b=5..............is the answer
For the answer to the question above,
and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n
0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem
if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10
then I would stop here
because I didn't see the choices. So the answer is 4n
The value of the car after 5 years would be $23914.85
<u>Explanation:</u>
Given:
Worth of the new car = $50,000
Every 5 years the value depreciates by 1/2
i.e., every 5 years the value depreciates by 50%
So, we can say that every year the value depreciates by 10%
The worth of the car after 7 years would be

where,
W is the depreciated value
C is the current value
D is the depreciation rate
t is the time
Substituting the value in the equation we get:

Therefore, the value of the car after 5 years would be $23914.85
Answer:
The missing volume of gas is 6 liters
Step-by-step explanation:
The following data points represent the volume of gas in each race car driver's tank (in liters):
4,5, 13, ?
Let the missing value be x
Data : 4,5,13,x



28=22+x
28-22=x
6=x
Hence The missing volume of gas is 6 liters
Answer:
B. g(x)
Step-by-step explanation:
g(x) is a function of odd degree, so will tend toward negative infinity as an extreme value.
f(x) is an even-degree function with a positive leading coefficient. Its minimum value is -2.
g(x) has the smallest minimum value
