Let w be the width and l the length of the rectangle. 
Then: \frac{l}{w}= \frac{1+\sqrt5}{2}  \text{ and }lw=104
Solving the above system we get:
l= \frac{1+\sqrt5}{2}w\\= \frac{1+\sqrt5}{2}\frac{104}{l}
Therefore:
l^2=\frac{1+\sqrt5}{2}104 then l=13,which is the length, 
And then the width w=\frac{104}{13}=8

Agata [3.3K]

The number of people who like black coffee i) 52

Number of the people who don't like any of the drinks ii) 66

<h3>What is probability?</h3>

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

This sort of problem is usually solved using some sort of table or Venn diagram. We have used a table in the attachment such that each of the cells in the grid represents one of the 8 possible combinations of coffee, tea, or chocolate.

The numbers in black are given directly by the problem statement. The numbers in blue are calculated from the numbers in black and one of the other given numbers in the problem statement. The numbers in red are calculated so the totals work out correctly.

The cells shaded blue-gray are "one and only one" of the drinks. The cell-shaded purple-gray is "don't like any".

i) black coffee

We assume that any form of "coffee" is "black coffee." The problem statement tells us that 52 people like coffee.

ii) none

The last number we calculated is the number who like none of the drinks: 66. This brings the total of non-coffee drinkers to 148.

Additional comment

As noted above, the colors more or less indicate the order of the calculations. We started with 36 who like coffee only, and 46 who like coffee and not tea. That means 46-36=10 like coffee and chocolate, but not tea.

Since 16 like coffee and chocolate, that leaves 16-10=6 who like coffee and tea and chocolate (all three).

96 like chocolate, but 16 of those like chocolate and tea. The other 80 like chocolate, but not tea.

46+16=52, so there must be 0 who like coffee and tea, but not chocolate.

The number who like only one is 108. We already have 36 that are coffee only, 80-10 = 70 that are chocolate only, so there must be 108 -70 -36 = 2 who like a tea only.

Now, we can finish filling the top row of the table and the totals in the bottom row.

Therefore the number of people who like black coffee i) 52 , Number of the people who don't like any of the drinks ii) 66

QUESTION
yanalaym [24]

Answer:

$97,958.42

Step-by-step explanation:

To solve this problem we can use the compound interest formula which is shown below:

A=P(1+r )^{t}

<em>P = initial balance </em>

<em>r = interest rate </em>

<em>t = time </em>

<em> </em>

First change 6.5% to its decimal form:

6.5% -> \frac{6.5}{100} -> 0.065

Next plug in the values:

A=49,000(1+.065)^{11}

A=97,958.42

They have to pay back $97,958.42
