Answer:

Any collection of lengths (a, b, c) which do not satisfy the triangle inequalities.

Step-by-step explanation:

Any collection (a, b, c) which do not satisfy the triangle inequalities. The inequalities:

a + b > c

b + c > a

a + c > b

You will need to test all of your options on the three inequalities above. If any one of the three fails, the collection won't work.

A hot air balloon descends 15 feet each minute after having reached an altitude of 362 feet above the ground. What is the altitu

salantis [7]

Answer:

182 feet

Step-by-step explanation:

The equation that describes the motion of the hot air ballon is:

$h(t) = h_0 - vt$

where:

$h_0$ is the initial altitude

v is the rate of descend of the balloon

t is the time

The balloon starts from a height of

$h_0 = 362 ft$

and has a rate of descend of

$v=15 ft/min$

Therefore, after time

t = 12 min

Its altitude will be

$h(12)=362 - (15)(12)=182 ft$

1. H=4
W=8

2. L=27
W=21

1. 160÷5=32

2. 2×6=12
96-12=84
84÷4=21
21+6=27 (the length)
