An airplane is at 32,000 ft above sea level and descends at an average rate of 1,000 ft per minute. How many minutes will it tak

slavikrds [6]

29 minutes- at a rate of 1,000 feet a minute, it would take 32 minutes to reach sea level (32,000/1000=32)but if you subtract 3000 from 32000 to remain 3000 feet above sea level, you have 29000 feet to descend which will take 29 minutes

1/5 PART OF A POLE IS INSIDE THE MUD, 2/3 PART IS INSIDE THE WATER AND THE REMAINING LENGTH OF 10m IS ABOVE THE SURFACE OF THE W

Andrei [34K]

Answer:

1/ 5 and 2/3

cross multiple

example

1 2 = 10

/ x / = /

5 3 3

= 10/3

so it's 3 1/3 + 10 Mm

so may guess is

13.3333 infinite or 13.34 M

Dont know if its right but good luck

The area of a piece of land that is in the shape of a triangle is 1/12 square mile. One dimension of this piec of land is 4/21.

Arisa [49]

Answer:

D2=21/24 mile

Step-by-step explanation:

Her it is not specified if it is base or height, it only talks about dimensions, so let's work with dimensions

A=1/12 $mile^{2}$

D1=4/21mile, D2=?

Area of a triangle $A=\frac{b.h}{2}$

A=((D1*D2)/2) → 2A=D1*D2 → D2=2A/D1 so D2=(2*1/12)/(4/21) =(1/6)/(4/21) = (1*21)/(6*4)=21/24 mile

sume of angles of a triangel greater than 180 degrees when teh triange is so large that it extends to cosmological scales

Vesna [10]

In hyperbolic geometry, the angle sum of a triangle is always less than 180 degrees.

A lune is a wedge of a sphere with angle θ, represented by L(θ) in the proof.

α, β, and γ are the three angles of the triangle.

4πr²+4area[αβγ]=2L(α)+2L(β)+2L(γ)

2(2πr²+2area[αβγ])=2(L(α)+L(β)+L(γ))

2πr²+2area[αβγ]=L(α)+L(β)+L(γ)

At this point, we need to use a theorem that states that a lune whose corner angle is θ radians has an area of 2θr².

2πr²+2area[αβγ]=2αr²+2βr²+2γr²

2πr²+2area[αβγ]=2r²(α+β+γ)

π+area[αβγ]r²=α+β+γ

At this point, it is clear that the sum of the angles is equal to π plus the area[αβγ]r² (which cannot be zero).
