Find the number of positive integers less than 100,000 whose digits are among 1, 2, 3, and 4. Hint consider the

Verdich [7]

Answer:

1364 is the number of possibilities for positive integers less than 1,00,000.

Step-by-step explanation:

1. 5 digit numbers:

We have 5 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 5 digit numbers:

$4 \times 4 \times 4 \times 4 \times 4\\ \Rightarrow 1024$

2. 4 digit numbers:

We have 4 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 4 digit numbers:

$4 \times 4 \times 4 \times 4 \\ \Rightarrow 256$

3. 3 digit numbers:

We have 3 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 3 digit numbers:

$4 \times 4 \times 4 \\ \Rightarrow 64$

4. 2 digit numbers:

We have 2 places here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 2 digit numbers:

$4 \times 4 \\ \Rightarrow 16$

5. 1 digit numbers:

We have 1 place here, and each place can have 4 options because repetition is allowed.

So, total number of possibilities for 1 digit numbers:

$4$

We can add all the above possibilities to find the total.

So, number of positive integers less than 100,000 whose digits are among 1, 2, 3, and 4 = 1024 + 256 + 64 + 16 + 4 = 1364

Jim has only dimes and nickels in his coin bank. He has 37 coins with a total value of $2.65. How many nickels are in Jim's coin

LekaFEV [45]

Answer:

$21\ nickels$

Step-by-step explanation:

we know that

$1\ nickel= \$0.05$

$1\ dime= \$0.10$

Let

x-------> the number of nickels

y-------> the number of dimes

$x+y=37$ ------> isolate the variable y

$y=37-x$ --------> equation A

$0.05x+0.10y=2.65$ ------> multiply by $100$ both sides

$5x+10y=265$ -------> equation B

Substitute equation A in equation B and solve for x

$5x+10(37-x)=265$

$5x+370-10x=265$

$10x-5x=370-265$

$5x=105$

$x=21\ nickels$
