Let t be time and r be rate, then if time varies inversely with the rate, the equation is
. If it takes 5 hours to drive a fixed distance at a rate of 80, we can sub those values in to solve for the constant of variation, k.
. Solve for k by multiplying 5 and 80 to get that k = 400. Now let's find a new time t when r is a rate of 70. We will use that k value to do this:
and find that it will take 20 hours to drive the distance at 70 mph when it takes 5 hours to drive the distance at 80 mph. Makes sense that it takes longer to drive a fixed distance when you are going slower.
Answer: 0.875
i hope this helps you could also go to your calculator and type it in, but glad to help if i did
Answer:
150
Step-by-step explanation:
89.517=90. 59.84=60 90+60=150
<span>Thus, a product that normally costs $199 with a 5 percent discount will cost you $189.05, and you saved $9.95.</span>
<span>You can also calculate how much you save by simply moving the period in 05.00 percent two spaces to the left, and then multiply the result by $199 as follows: $199 x .05 = $9.95 savings.</span>
<span>Furthermore, you can get the final price by simply deducting .05 from 1 and multiplying it by $199 as follows: (1 - .05) x $199 = $189.05 final price. </span>
<span>If something costs $199 and is on sale for 5% off, then how much would it cost? Here we will show you how to calculate how much you save (discount) and how much you have to pay if something you want to buy is regularly $199, but is currently on sale for 5 percent off.
<span>$199
<span>SALE
</span>5% OFF</span>
There are many ways of calculating your discount and final purchase price. One way is to multiply 199 dollars by 5 percent, and then divide the answer by one hundred, then deduct that result from the original price. See illustration below:
+ Purchase Price = $199
- Discount (199 x 5)/100 = $9.95
<span>= Final Price 199 - 9.95 = $189.05
