65.13 / 3.9 = 16.7 meters = length
16.7 + 16.7 + 3.9 + 3.9 = 41.2 meters = perimeter

A candy store sells 7 packs of bubble gum for $29.33. How much would it cost to buy 3 packs?
alexira [117]

Hi there,

Recall how 7 packs for gum sell for $29.33.

Before we can calculate how much it would cost to sell 3 packs of gum, we must calculate how much it would first cost to sell 1 pack of gum.

The cost of 1 pack of gum is the current total cost divided by the total amount of gum packs you receive at that price.

In this case, the total cost is $29.33, and we receive 7 gum packs at that price.

Therefore, the cost of 1 pack of gum is \frac{29.33}{7}, which equates to $4.19.

We now know that each pack of gum costs $4.19.

Hence, 3 packs of gum would cost three times that price.

4.19 * 3 = 12.57

The cost of 3 packs of gum is $12.57.

Hope that helps!

119. Beatrice decides to deposit $100 per month at the end of every month in a bank with an annual interest rate of 5.5% compoun
sveta [45]

Answer:

Beatrice will accumulate $1230.72 at the end of the year.

Step-by-step explanation:

We can write:

(1+\frac{0.055}{12})=z

100=C for deposits

The first month would have only the deposit reflected in her balance, then, expanding some steps of the calculation would yield:

S_{1}=C\\S_{2}=Cz + C\\S_{3}=Cz^{2}+Cz + C\\S_{n}=Cz^{n-1} +...+Cz+C

A geometric series is given by:

1+x+...+x^{m}=\frac{x^{m+1}-1}{x-1}

Translating our series to the short form:

S_{n}=C(\frac{z^{n}-1}{z-1} )

plugin in the values for the 12 month gives:

S_{12}=100(\frac{(1+\frac{0.055}{12})^{12} -1}{\frac{0.055}{12}})=1230.7169

You have saved 18000 for a down payment on a house. Your bank requires a minimum down payment of 11%. What is the maximum price
zhenek [66]

Money saved for down payment = 18000

Minimum down payment required by the bank = 11%

Let the maximum price that can be offered be = P

\frac{11}{100}P=18000

11P=1800000

P=163636.36

Hence a maximum price of 163636.36 can be offered for a home that can have a down payment of 18000.
