Answer:
700
Step-by-step explanation:
The '7' in the number 1273 ..it is in the second place which represents 'tens' so it is equal to '70' ten times this amount would be 700. If you have a list of numbers to choose from.....choose one with the '7' in the THIRD position.
Answer: a) 59049, b) 15120, c) 126.
Step-by-step explanation:
Since we have given that
5 digit sequences from the integers 1,2,...9.
a) the digits can be the same.
Repetition is allowed.
So, Number of ways to form 5 digit sequences would be
b) the digits cannot be the same and the order in which they appear matters.
Repetition is not allowed and order is maintained, so we will use "Permutation":
c) the digits cannot be the same and the order in which they appear does not matter.
Repetition is not allowed and order is not maintained, so we will use "Combination":
Hence, a) 59049, b) 15120, c) 126.
Answer:
135
Step-by-step explanation:
2 x 54 = 108 and .50 x 54 = 27 so 108 + 27 = 135

Answer:
The answer to your question is 7 large and 16 small
Step-by-step explanation:
Data
cost large frame = $13
cost small frame = $5
total number of frames = 23
total cost = $171
large frame = l
small frame = s
Process
- Write equations that help to solve the problem
l + s = 23 Equation l
13l + 5s = 171 Equation ll
-Multiply equation l by -5
-5l - 5s = -115
13l + 5s = 171
8l + 0 = 56
8l = 56
l = 56/8
l = 7
-Find s
7 + s = 23
s = 23 - 7
s = 16
-Conclusion
She bought 7 large frames and 16 small frames.
