Answer:

47.6 Degree Fahrenheit

Step-by-step explanation:

Given:

The Airplane is on the ground level at a temperature 59.7 Fahrenheit. Every 1,000 feet there will be drop in temperature which is 1.1 degrees Fahrenheit.

Initial Temp = 59.7 Fahrenheit

Distance Covered = 11,000 Ft

Explanation:

This means the Ground level is zero feet as the Airplane stands there.

Later, it climbs into the sky with 11,000 altitude.

That is 11 * 1000

For every 1,000 there is decrease in temperature of 1.1 degree Fahrenheit

Therefore, 11 times the temperature will decrease

That is  11 * 1.1

12.1 Degree temperature will drop at 11,000 feet

Therefore

Temperature at 11,000 feet will be 59.7 - 12.1

47.6 Degree Fahrenheit

A right triangle has a hypotenuse of 10 mi. and a leg of 6 mi., what is the length of the other leg?
slava [35]

Answer:

8mi

Step-by-step explanation:

Using Pythagoras theorem

Hypotenuse square = opposite square + adjacent square.

Let the other leg be x

10 square = 6 square + x square

100 = 36 + x square

Collect like terms

X square = 100 -36

X square = 64

Find square root of both sides

X = square root of 64

X =8mi

A cone with a radius of 12 cm and a height of 12 cm has the same volume as a cylinder with a radius of 8 cm. What is the height
Dmitry [639]
First, substitute the given radius and given height of the cone into the formula for the volume of a cone. 

Volume of a cone:  (1/3) pi r^2 h
In this case, the cone volume is (1/3) pi (12 cm)^2 (12 cm) = 576 cm^3

Vol. of a rt. cylinder:  pi r^2 h
In this case, the vol. of the rt. cyl. is pi (8 cm)^2 h.

The two different shapes have the same volume.  Therefore, set the two formulas (above) equal to each other:

576 pi cm^3 = pi (8cm)^2 h.  This becomes

576 pi cm^3 = pi (64 cm^2) h.  "pi" cancels out, leaving us with

576 cm^3
------------- = h.       This is the height of the cylinder, in cm.
 64 cm^2

If A and B are events with P(A)=0.7, P(A OR B)=0.77, and P(A AND B)=0.13, find P(B).
Rufina [12.5K]

Answer:

  P(B) = 0.20

Step-by-step explanation:

For these events, which are not independent or mutually exclusive, the relation between the various probabilities is ...

  P(A or B) = P(A) +P(B) -P(A and B)

Solving for P(B), we find ...

  P(B) = P(A or B) +P(A and B) -P(A)

  P(B) = 0.77 +0.13 -0.7 = 0.20

The probability of B is 0.20.

__

<em>Additional comment</em>

The formula applies to independent and mutually exclusive events, as well. For independent events, P(A and B) = P(A)·P(B). For mutually exclusive events, P(A and B) = 0.
