Answer:

Each month: y = 12(3x - 7)

12 months: y = 36x - 42

Step-by-step explanation:

We are told that her plants grow by 7" subtracted from the product of a number and 3" inches each month.

Now, let the number be x.

Also, let y denote how much her plants grow each month.

Thus, each month, her plants will grow by;

y = 3x - 7

Since 1 month, it grows by y = 3x - 7

Then, for 12 months, it will grow by;

y = 12(3x - 7)

y = 36x - 42

A new aircraft control system is being designed that must be 98.0% reliable. This system consists of two components in series.

sweet [91]

Answer:

98.99%

Step-by-step explanation:

The combined reliability of both components must be 98%. Given that both components must be functional and have the same reliability 'r', the minimum value of 'r' that meets the system requirements is given by:

$0.98 = r^2\\r=0.9899=98.99\%$

The level of reliability required for each component is 98.99%.

A store charges a restocking fee for any returned item based upon the item price. An item priced at $200 has a fee of $12. An it

lyudmila [28]

Answer:

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.

Step-by-step explanation:

For the $200, the restocking fee is $12, so the ratio of the restocking fee to the price of the item is 12/200.

For the $150, the restocking fee is $9, so the ratio of the restocking fee to the price of the item is 9/150.

Now we find out if the ratios 12/200 and 9/150 are equal.

12/200 = 3/50

9/150 = 3/50

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.

GuDViN [60]

Answer:

At the end of the party 5.5 gallons or 88 cups of punch will be leftover.

Step-by-step explanation:

Given:

There are 20 guest at a party.

Now, to find the quantity of punch that will be leftover.

Number of guests = 20.

Total gallons of punch = 8.

Now, using conversion factor we change gallons into cups:

1 gallon = 16 cup.

So, 8 gallons = 16 × 8 = 128 cups.

Thus, total cups of punch = 128.

Total number of cups each guest will drink = 2.

Now, to get total number of cups the 20 guests will drink by multiplying:

$20\times 2$

$=40\ cups.$

Total number of cups the 20 guests will drink = 40.

So, to get the leftover punch we subtract the total number of cups the 20 guests will drink from total cups of punch:

$128-40\\\\=88\ cups.$

So, 88 cups = $88\div 16=5.5\ gallons.$

Therefore, at the end of the party 5.5 gallons or 88 cups of punch will be leftover.
