An hour is 60mins or 1 rotation
so
the hand moves 35/60 of the circumference of the clock
so
c=2pir
r=length of hand=7
c=2pi7
c=14pi
then, we have 35 out of 60 mins or 35/60=7/12
7/12 times 14pi=98pi/12=49pi/6≈25.66 inches
LCM= 40
factors of 5- 5, 10, 15, 20, 25, 30, 35, 40*
factors of 8- 8, 16, 24, 32, 40*
If you decrease a price by 20% you multiply the original cost by 0.8
So, if y times 0.8 = $12, then you do y=12/0.8 which is 15.
The original cost is $15.
Answer: The price change per year is a rate of change because it describes how an output quantity changes relative to the change in the input quantity.
ARC= change in output/chnge in input
Answer:
y = 3
Step-by-step explanation:
Since ABCD is similar to EFGH, therefore, the ratio of their corresponding sides are equal. Thus:
AB/EF = CD/GH
AB = 3
EF = 2
CD = 4.5
GH = y
Substitute
3/2 = 4.5/y
Cross multiply
3*y = 4.5*2
3y = 9
Divide both sides by 3
3y/3 = 9/3
y = 3
