Since the slope is (change in y)/(change in x), and a negative number over a positive number is negative (and vice versa), we want to figure that out. Therefore, we would want 2 to be bigger than the x value and 8 smaller than the y value, or the other way around. (0,9) fits the description, as well as (5, 6)
A) 130 mins = 2 hours 10 mins or 2 and 1/6 hours... so 2 and 1/6 revolution. and 1 revolution is equal to 2*pi radians
<span>ANSWER: 13/6 (2 and 1/6) * 2*pi = 13.6 radians </span>
<span>b) 8/13.6 = x/(13/6) so x = 0.2715 hours or 16 and 1/3 minutes </span>
<span>c) if the restaurant is 21 meters, the radius is 10.5 meters, and the circumference is 2*pi*r so circumference = 65.97 meters. </span>
<span>2 and 1/6 revolution is going around the circumference 2 and 1/6 times, so simply multiply 65.97 by 13/6 </span>
<span>ANSWER: about 143 meters</span>
Answer:
$35
Step-by-step explanation:
50 * 30% = 15$ discount
50 - 15 = 35$ cost
30% discount is additional so based off sales price
Answer:
$5x + $7y ≥ $220
Step-by-step explanation:
Total Fees = $220
Total income is $5x plus $7y
Income = $5x + $7y
We want the total income to be equal to, or greater than, $220:
$5x + $7y ≥ $220
