An airplane's change in altitude before landing in shown in the table. What equation represents this change in altitude

Ray Of Light [21]

Answer

-4,000

Step-by-step explanation:

Just subtract 35,000 and 31,000 or 27,000 and 21,000 and get 4,000. Since the altitude is going down, it'll be negative.

Determine the unknown angles in the diagram above. Please help!

Nana76 [90]

a and 143 are supplementary. So a + 143 = 180

a + 143 = 180 Subtract 143 from both sides.

a = 180 - 143

a = 37

b and 143 are vertically opposite angles and are equal

b = 143 degrees.

Interior angles on the same side of a transversal for parallel lines are supplementary

b + c = 180

143 + c = 180

c = 37

c + d + 85 = 180 degrees

37 + d + 85 = 180

d + 122 = 180

d = 180 - 122

d = 58

e = c They are vertically opposite.

e =37

All triangles have 180 degrees.

e + f + 90 = 180 degrees.

37 + f + 90 = 180

f + 127 = 180

f = 180 - 127

f = 53

G and 48 are opposite 2 equal sides. So G and 48 are equal

G = 48

h + 48 + 48 = 180

h + 96 = 180

h = 84

K and H are supplementary

K + H = 180

k + 84 = 180

k = 95

m+ k + d = 180

M + 95 + 58 = 180

M + 143 = 180

M = 37

the top angle is 2*m and 2m is bisected. You are using the m on the left.

P + 85 + M = 180

P + 85 + 37 = 180

P + 122 = 180

p = 180 - 122

p = 58

r + p are supplementary.

r + p = 180

r + 58 = 180

r = 180 - 58

r = 122

s + r + c + b = 360 All quadrilaterals have 360 degrees.

s + 122 + 37 + 143 = 360

s + 302= 360

s = 360 - 302

s = 58

Some help please stuck on 4, 8, 9

bulgar [2K]

4:
a) if a cloud is a mid-level cloud, then it is between 6,500 and 20,000 feet.
b) if a cloud isn't a mid level cloud, then it is not between 6,500 and 20,000 feet. [I don't know if this statement is true]
8:
P=2l+2w
solve for w means to make the equation like w=... (get w on one side by itself).
First, subtract 2l from both sides
P-2l=2w
Now, divide both sides by 2
${P-2l}{2}$ = $W$
Done
9:
*The question is a bit wrong here; it should have said In the corner of the angle ABC there is a little square symbol - that means it is a 90 degree angle.
The angle ABC is broken up into angles ABD and DBC, so ABD and DBC add up to 90 degrees.
So, we can make the equation (2x + 10) + (x + 14) = 90
Then solve
Since it is all addition, the parentheses are unnecessary
2x + 10 + x + 14 = 90
Add all x terms together, and the numbers together
3x + 24 = 90
Subtract 24 from both sides
3x = 66
Divide both sides by 3
x = 22
Now, plug in this x value into the formulas for the two angles
ABD = 2(22) + 10 = 44+10 = 54 degrees
DBC = 22 + 14 = 36 degrees
