Answer:

Part A) The correct Expression : (1.05)(190)(0.8)

=> The error of Joel was that instead of adding the sales tax, he subtracted it.

Part B) $159.60

Step-by-step explanation:

Part A:

To calculate the computer cost, we need to find out the selling price first.

There's a discount of 20% so the selling price will be 100% - 20% = 80% =>80/100 = 0.8

So, We'll multiply the cost price by 0.8

=> (190)(0.8)

But, there is a sales tax of 5%

So, the selling price with cost price will be:

=> 100% + 5% = 105% => 105/100 = 1.05 (We'll multiply this too with the first equation that we made above)

So, the expression will be:

=> (1.05)(190)(0.8)

The error of Joel was that instead of adding the sales tax, he subtracted it.

Part B)

Joel will pay for the tablet:

=> (1.05)(190)(0.8) [We used the above expression]

=> $159.60

3. if you want to represent geologic time with a 24-hour clock, how many years would be represented by a single second, minute a

Amanda [17]

In geologic time scale a single second = 52,083.3 years, a minute = 3,125,000 years, an hour = 187.5 million years

Geologic time, the extensive interval of time occupied by the geologic history of Earth. Formal geologic time begins at the start of the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day.

So the geologic time scale (GTS) contains different ranks of times about Earth, obviously you know this already. However, the GTS has these different ranks in order from shortest length of time to longest length of time.

The Earth is about 4.5 billion years old. We want to convert this geological time in a period of 24 hours. So, if 24 hours correspond to 4.5 billion years, then, 1 Hour= 4.5 billion / 24=187.5 million years. There are 60 minutes in an hour ∴ 1 minute =187.5 million /60=3,125,000 years finally, one second has 60 seconds ∴ 1 second=3,125,000 / 60 = 52,083.3 year.

Kelly is having a party. She wants to make punch. The recipe for punch uses 3 pints of pineapple juice, 5 cups of orange juice,

lorasvet [3.4K]

Answer:

Kelly is wrong and the recipe will make 19 cups of punch.

Step-by-step explanation:

It says:

The amount of ingredients in the recipe of punch after converting the units to 'cups' are given by,

Pineapple juice = 3 pints = 6 cups (1 pint ≈ 2 cups)

Orange juice = 5 cups

Lemonade = 1/4 gallon = 4 cups (1 gallon = 16 cups)

Apricot nectar = 1 quart = 4 cups(1 quart = 4 cups)

Then, the total cups of punch = 6 + 5 + 4 + 4 = 19 cups.

Thus, Kelly is wrong and the recipe will make 19 cups of punch.
