For starters, the probability of finding any of these colors is a 50/50 type of thing, or in this case, an equal quarter. So each would be 1/4, or 25%. Unless, of course, they're lying about having one or more colors of marbles in their possession. But I'm answering under the assumption that they're not.

Answer:

$\large{\boxed{35_{10} = \sf 23_{16}}}$

Explanation:

$\sf Given : 35_{10}$

Compute:

35 ÷ 16 = 2.1875 = 2R3

2 ÷ 16 = 0.125 = 0R2

Jot down the remainders:

2 ↑

======

$\sf Answer : \ 35_{10} = 23_{16}$

$\hrulefill$

Let's look at another example: $\sf 325_{10} = [?]_{16}$

Compute:

325 ÷ 16 = 20.3125 = 20R5

20 ÷ 16 = 1.25 = 1R4

1 ÷ 16 = 0.0625 = 0R1

Jot down remainders:

=====

$\sf 325_{10} = [145]_{16}$

$\hrulefill$

Another example: $\sf 500_{10} = [?]_{15}$

Compute:

500 ÷ 15 = 33.33... = 33R5

33 ÷ 15 = 2.2 = 2R3

2 ÷ 15 = 0.13... = 0R2

Jot down remainders:

=====

$\sf 500_{10} = [235]_{15}$

94 passengers rode in a train from City A to City B. Tickets for regular coach seats cost 115$. Tickets for sleeper cars seats

Kisachek [45]

Using a system of equations, it is found that 41 regular and 53 sleeper seat tickets were sold.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Variable x: Regular coach seats.

Variable y: Sleeper cars seats.

94 passengers rode in a train from City A to City B, hence:

$x + y = 94$

Tickets for regular coach seats cost 115$. Tickets for sleeper cars seats cost 281$. The receipts for the trip totaled 19,608$, hence:

$115x + 281y = 19608$

From the first equation, x = 94 - y, hence, replacing on the second.

$115x + 281y = 19608$

$115(94 - y) + 281y = 19608$

$166y = 8798$

$y = \frac{8798}{166}$

$y = 53$

$x = 94 - y = 94 - 53 = 41$

Hence, 41 regular and 53 sleeper seat tickets were sold.
