The perimeter of a square in which A=169cm square root 2?

sergey [27]

I'm guessing you mean:
$A = 169 \sqrt{2}$

If not, correct me.

So, then the perimeter of a square is just 4*A, which in this case would be:
$4(169 \sqrt{2}) = 676 \sqrt{2}$

And that would be your answer: $676 \sqrt{2}$ units²

Angles M and N are complementary. The measure of M is 27°. What is mN?

finlep [7]

Answer:

A. 63 degrees

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees. You can make an equation to solve for angle N:

27 + x = 90

rearrange the equation:

90 - 27 = x

63 = x

A plane is descending into an airport. When its altitude is 3 1/2 miles, it is 250 miles from the airport. When its altitude is

shepuryov [24]

Answer: 1/2 miles

Step-by-step explanation:

Given the following:

Altitude (miles) - - - - - - - - - - distance (miles)

3 1/2 - - - - - - - - - - - - - - - - - - - 250

2 1/2 - - - - - - - - - - - - - - - - - - - - 175

Calculate the plane's altitude at 25miles from the airport

7/2 = 250

5/2 = 175

(7/2 - 5/2) miles = (250 - 175)miles

1 mile = 75 miles

From the above, the plane craft 's altitude reduces by 1 mile for every 75 miles moved

Therefore, at a distance of 25 mile from the airport,

Distance moved = (250 - 25)miles = 225miles

225miles / 75 miles = 3

Therefore, the altitude will reduce by 3 miles from the initial altitude at 250 miles

Therefore,

( 3 1/2 - 3) miles = 1/2 miles

Therefore, the plane craft will have an altitude of 1/2

Please help me with this probability problem.

lesya692 [45]

Answer:

0.308

Step-by-step explanation:

You have 8 nickels and 6 dimes. 8 + 6 = 14.

You know both of the coins you have picked are nickels so you will have to find the probability of picking a nickel and then another nickel.

First time: $\frac{8}{14}$ is the probability of picking a nickel the first time.

Second time: Since you don't have a nickel in your pocket anymore, you now have 7 nickels and 6 six dimes in your pocket. Together you have 13 coins. You have 7 nickels so you have a $\frac{7}{13}$ chance of picking another nickel out of your pocket.

To find the probability of this event you do $\frac{8}{14}$ * $\frac{7}{13}$ because to find the probability of A and B you do P(A) multiplied by P(B). If you wanted to find the probability of getting A or B you would add together instead of multiplying.

Multiplying these together gets you 0.307692... which is 0.308 rounded.
