Answer:
The population of California is about 5 times the population of south Dakota
Step-by-step explanation:
Let
x ------> the population of California
y -----> the population of south Dakota
we have
x=4,000,000 people
y=800,000 people
Divide the population of California by the population of south Dakota, to find out how many times the population of South Dakota is the population of California
so
x/y
substitute
4,000,000/800,000=5
therefore
The population of California is about 5 times the population of south Dakota
Answer:
t=5W+30 or C
Step-by-step explanation:
The pool already has 30 in it so you would initially be adding it, not multiplying it to anything. Then since every second 5 gallons of water is being added to the pool, you add the 30 gallons the pool already contains to 5W.
12+11+24 is 43 and subtract that by 3 which is 40
Answer is C

Answer:
(200π - 12)ft
or
616.32 ft
Step-by-step explanation:
Given in the question,
there are four circle around which corn will be planted.
radius of first circle = 10 ft
radius of second circle = 20 ft
radius of third circle = 30 ft
radius of fourth circle = 40ft
circumference = 2πr
First circle
2π(10)-3
20π -3
Second circle
2π(20)-3
40π-3
Third circle
2π(30)-3
60π-3
Fourth circle
2π(40)-3
80π-3
Add them up
80π - 3 + 60π - 3 + 40π - 3 + 20π - 3
(200π - 12)ft
or
616.32 ft
