Answer:
<h2>48.4° C</h2>
Step-by-step explanation:
Step one:
We are told that there is 1.1° drop in temperature for each 1000 ft climb.
since the given altitude is 11,000ft,
hence there =(11000/1000)*1.1
= 11*1.1
=12.1°C drops in temperature.
Therefore, given that the temperature on the ground is 60.5° C
The temperature above is 60.5-12.1=48.4° C
<u>The plane reaches an altitude of 11,000 is 48.4° C</u>
Answer:
The direction angle of vector v is equal to 
Step-by-step explanation:
Let
The vector v is given by
Remember that
The direction angle of the vector is equal to
substitute the values
Use subtraction to find the lengths of segments WX and XY.
Point W is on (9,3), point X is on (5,3) and point Y is on (5,9), if I'm reading this correctly.
Point W and point X match with their y-values, so we ignore them. Subtract the x-values, 9 and 5, to get the length. In this case, the length is 4 units.
Point X and point Y match with their x-values, so we ignore them. Subtract the y-values, 3 and 9, to get 6.
Since the problem is asking for length, you always subtract the smaller number from the larger one, as you can't have a negative distance or length.
Area= length*width
width=W
W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)
Answer:
Step-by-step explanation:
Sally owes 7 dollars to Matthew. She opens her piggy bank and takes out 7 dollars. Now, how much money does she owe to Matthew?
-7 + 7 = 0
-7 + 7 is the same as 7 - 7
You can clearly see that 7-7 is 0.
