Eight adults and two children need to cross a river. A small boat is available that can hold one adult or one or two children. E

sleet_krkn [62]

Answer:

A = 8, C = 2 => T = 33

A=100, C = 2 => T = 401

A = any, C = 2 => T = 4A + 1

A = 8, C = 4 => T = 37

As long as the boat can carry one adult or one or two children, the following equation should solve the problem.

T = 4A + 2(C-2) + 1

Step-by-step explanation:

To transfer one adult, 4 one-way trips need to be made as follows:

1. Two children cross the river

2. One of them takes the boat back to the other side

3. One adult crosses the river

4. The other child takes the boat back

These four steps are repeated until all adults are crossed. At this point no children has crossed yet.

Then for every 2 children except the last 2, 2 one-way trips need to be made if the number of children is greater than 2:

1. Two children cross

2. One takes the boat back

For the last 2,only one trip needs to be made.

A = number of adults

C = number of children >= 2

T = total trips

T = 4A + 2(C-2) + 1

Convert 45 32’ 55” into decimal degrees to the nearest two decimal places

denis23 [38]

The decimal equivalent of 45⁰ 32’ 55” is 45.55⁰

<h3>Converting degrees into decimal</h3>

The given degree is:

45⁰ 32' 55''

This can be converted to decimal as shown below

$45+\frac{32}{60} +\frac{55}{3600}$

This can be simplified further as:

$45^o32'55'' = 45+0.53+0.0153\\\\45^o32'55'' = 45.55^0$

Therefore, the decimal equivalent of 45⁰ 32’ 55” is 45.55⁰
