(a)
Let's assume
number of nickels is n
total number of coins is 21
so, number of dines will be 21-n
1 nickel =$0.05
1 dimes=$0.10
total value is 1.65
so, we can set up equation
now, we can solve for n
so, number of nickels is 9
number of dimes is 21-9=12..........Answer
(b)
we are given
value of the nickels =5n
we know that
value of dimes =2* value of nickels
so, we can plug it
value of dimes =2*5n
value of dimes =10n...............Answer
Answer:
y = -1/6x - 1.
Step-by-step explanation:
I am assuming that the point id (6, -2).
The slope of the required line = -1/6.
y - y1 = m(x - x1) where m = slope and x1,y1 is a point on the line so we have
y - (-2) = -1/6( x- 6)
y + 2 = -1/6x + 1
y = -1/6x - 1.
Answer:
362,880 different
Step-by-step explanation:
Use the permutation 9*8*7*6*5*4*3*2*1. Since there are 9 possible players for the first position, 8 for the 2nd (1 is taken off), 7 for the 3rd, etc. So you would multiply these numbers together. So there are 362,880 different possible batting orders.
Answer:
6p - 2
Step-by-step explanation:
The expression that needs to be made in this question refers to the total number of people that signed the petition. To calculate this we need to add the total number of signatures that both you and your friend were able to acquire. Once we do this we simply combine like terms in order to simplify the expression as much as possible.
4p + 5 + 2p - 3
4p + 2p + 5 - 3
6p - 2
Therefore, the total and simplified expression for the total number of signatures would be 6p - 2
The horizontal line at y=4 doesn't have any slope, so the answer should be relatively easy to find. It's just the slope of Function 2.
y = 8x + 12 is the function for Function 2. 8x is the important part.
So the rate of change differing from both functions is 8.
