Luis wants to buy a skateboard that usually sells for $79.91. All merchandise is discounted by %12. What is the total cost of th
quester [9]

Answer:

Luis' skateboard will cost $76.32.

Step-by-step explanation:

Divide 79.91 by 100, this is what one percent is worth, .7991.

Multiply this by 12, giving you 12 percent, 9.59 (rounded to the nearest 10th).

Now subtract 9.59 from 79.91, 70.32. That is the price BEFORE tax.

Than divide 70.32 by 100, .7032.

Multiply this by 8.25, 5.80, this is tax.

Now add the price before tax, 70.32, to the tax, 5.80.

This creates 76.12. This means that the total price of the skateboard is $76.32.

frosja888 [35]

The formula to calculate the temperature (T) after m minutes is -

T = 106 - 6m

We have Reabilwe who is conducting an experiment in which the temperature is measured carefully. The temperature was 106°C at the end of the first minute, and then it falls by 6°C every minute after that.

We have to tp determine a formula to calculate the temperature (T) after m minutes.

<h3 /><h3>Starting from x, if the bacteria count rises by 5 every second, then determine the formula to calculate the bacteria count after 30 seconds.</h3>

Initial count = x

Count increasing per second = 5

Assume that the bacteria count after t seconds is y. Then -

y = x + 5t

for t = 30 ↔ y = 150 + x

According to question, we have -

Initial Temperature = 106 degrees Celsius

Temperature increase per minute = 6 degrees Celsius

Assume that the Temperature fall after m minutes is T. Then -

T = 106 - 6m

Hence, formula to calculate the temperature (T) after m minutes is -

T = 106 - 6m
