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)
Answer:
table
Step-by-step explanation:
You will get the same answers but with more zeros. For example 7x20 is 140, and 7x2000 is 14,000 but with more zero's
To find out how many did not raise money, we need to find the percentage that did not raise money and multiply that by the total number of members.
If 95% raised money, 5% did not raise money.
0.05 x 80 = 4 members did not raise money
The answer would just be 3xy since you can take out 3 and one x and a y
