You want to go to europe 5 years from now, and you can save $3,100 per year, beginning one year from today. you plan to deposit

Tanzania [10]

This is the concept of application of compound interest, to calculate the amount I will have after the 5th deposit we proceed as follows;
A=p(1+r/100)^n
where;
A=future amount
p=principle
r=rate
n=number of years
thus substituting the values in our formula we get:
A=3,100(1+8.5/100)^5
A=3,100(1+0.085)^5
A=3100(1.085)^5
A=4,666.34
The amount of money after 5 years will be $4,666.24

During the first hour of operation the farm stand owner sold 15% of the apples he had. On the second hour he sold 20% of the rem

Gnesinka [82]

Answer:

22.95 kg

Step-by-step explanation:

Let's say the farm stand owner starts with x kg of apples.

During the first hour, he sells 15% of the apples:

0.15 x

This means he's left with 85% of the original apples. During the second hour, he sells 20% of the remaining apples:

0.20 (0.85 x)

= 0.17 x

He's sold a total of 15% + 17% = 32% of the apples, so he's left with 68% of the apples. Continuing the pattern, the apples sold during the third hour:

0.25 (0.68 x)

= 0.17 x

He's sold 49% of the apples and is left with 51%. The apples sold during the fourth hour:

0.30 (0.51 x)

= 0.153 x

If 0.17 x = 25.5, then x = 150. So the apples sold during the fourth hour is:

0.153 (150) = 22.95

two cards are chosen at random from a deck of 52 playing cards. what is the probability that they are both aces?

drek231 [11]

Answer:

The probability that they are both aces is 0.00452.

Step-by-step explanation:

Consider the provided information.

Out of 52 playing card we need to select only 2.

Thus, the sample space is: $^{52}C_2=1326$

Two cards are Ace.

The number of Ace in a pack of playing card are 4 and we need to select two of them.

This can be written as: $^4C_2=6$

Thus, the probability that they are both aces is:

$P(\text{Both are Ace})=\dfrac{6}{1326} \approx0.00452$

Hence, the probability that they are both aces is 0.00452.

For every 15 columns of news stories in a newspaper, 4 columns of ads are required. If a newspaper contains 300 columns of news

Nady [450]

The problem can be solved by proportion as following

For every 15 columns of news stories in a newspaper, 4 columns of ads are required

If a newspaper contains 300 columns of news stories, x columns of ads are required
∴ 15 : 4 = 300 : x
∴ $\frac{15}{4} = \frac{300}{x}$
By using cross multiplication
∴ 15 x = 4 * 300
∴ 15 x = 1,200
∴ x = 1,200/15 = 80

So, the number of columns of ads must it have = 80
