The best way to justify which answers are correct are to calculate the circumference and the area for each of the circles with the given radii. I organized this information into a chart.
Circumference | Area
1/2 3.14 0.785
1 6.28 3.14
1 1/2 9.42 7.065
2 12.56 12.56
2 1/2 15.7 19.625
The first three choices will result in a numerical value for the radius that is smaller than the area.
The answer Is A :)))))))))))))
A=s^2, where s is a side length, and we are told A=150ft^2 so:
s^2=150
s=√150
s≈12.25 ft
So you would need a piece of carpet 13ft by 13ft
Answer:
0.1428 is the probability that both the pirate and the Captain hit each other's ships.
Step-by-step explanation:
We are given the following in the question:
Probability of captain hitting pirate's ship =
Probability of pirate hitting captain's ship =
If events are independent events, we can write:
We have to evaluate the probability that both the pirate and the Captain hit each other's ships.
0.1428 is the probability that both the pirate and the Captain hit each other's ships.
Answer:
To solve for n you need to get it by itself
First you want to distribute your 2 through the (3n+14)
-2n+6n+28=-20 (2*3n+2*14= 6n+28)
Now you want to combine any like terms if possible
4n+28=-20 (-2n+6n=4n, both like terms)
Then you want to subtract -28 from both sides
4n=-48 (28-28=0, -20-28=-48)
Lastly you want to divide both sides by 4
n=-12 (4n/4=n, -48/4= -12)
