Answer:
Step-by-step explanation:
1 ring has a radius of 3 feet
1 ring has a circumfrence of 2*pi*r = 2 * 3.14 * 5 = 10*Pi
5 rings would have a length of 50 * pi length = 50*3.14 = 157 feet
That's a lot of Brillo pads.
Ava took 5 minutes out of 60 in an hour to do half a mile
5×2=10
60/10=6mph
Damon took 3 minutes out of 60
3×2=6
60/6= 10mph
Reina took 4 minutes out of 60
4×2=8
60/8= 7.5mph

x = 50
The angles shown are vertically opposite and thus equal
so 3x - 30 = 2(x + 10)
3x - 30 = 2x +20
subtract 2x from both sides
3x - 2x - 30 = 20
x - 30 = 20
add 30 to both sides
x = 20 + 30 = 50
Answer:
y = 5 * (3^x)
Step-by-step explanation:A scientist begins an experiment with a culture of 5 bacteria cells.
Every hour, the number of bacteria cells triples.
Which equation can be used to represent the number of bacteria cells, y, as it relates to time in hours, x?
:
I think it would be y = 5 * (3^x)
