291.87 is rational since the last (decimal) numbers aren't repeating.
If it was repeating (291.877777...) it would be irrational.
Answer:
(y - 25) = - 0.25(x - 20)
Step-by-step explanation:
Given that :
Height of candle after burning for 20 minutes = 25 cm
Height after burning for 1 hr (60 minutes) = 10 cm
Height (y) in cm of candle x minutes after being lit:
Using the equation :
(y - y1) = m(x - x1)
m = (change in y / change in x)
Change in height within 60 minutes :
Height at 20 minutes = 25cm
Height after an hour = 10
Change in height per hour = (25 - 10) = 15cm
Hence, m = change in height per minute
15cm / 60 = 0.25cm ( - 0.25) (decrease in height)
y1 = 25 ; x1 = 20
(y - y1) = m(x - x1)
(y - 25) = - 0.25(x - 20)
She gets to the library at 5:30. Half an hour is equal to 30 minutes, and if she leaves at 5:00, she will be there in thirty minutes.
The purchasing price of the store = $29.25.
They want to resale it at 54% markup of the purchasing price.
54% of 29.25 = 0.54 × 29.25.
On multiplying 0.54 and 29.25, we get 15.795.
Resale price = The purchasing price + Markup
= 29.25 + 15.795.
On adding 29.25 and 15.795, we get 45.045.
We can round it to 45 to the nearest dollar.
<h3>Therefore, the resale price to the nearest dollar is $45.</h3>
Angle A because the opposite side is the smallest, the smallest side being 28.49.
