WILL GIVE BRAINLIEST The kilopascal is a unit of measure for atmospheric pressure. Suppose the atmospheric air pressure at sea l

evel is about 101 kilopascals. For every​ 1000-m increase in​ altitude, the pressure decreases about 11.9​%. What is the approximate pressure at an altitude of 2000 ​m?

Answer:

The formula to calculate pressure at an altitude in this case is:

P = original pressure x (1 + rate of change)^(number of changing)

in which,

original pressure = 101 kilopascals

rate of change = -11.9% = - 0.119

number of changing = 2000/1000 = 2

=> P = 101 x (1 - 0.119)^2 = 78.39 kilopascals

Hope this helps!

List of sides in order from shortest to longest 
kirill [66]

Answer:

x = 12

m∠A = 104º

m∠B = 32º

m∠C = 44º

shortest side = B

middle side = C

longest side = A

Step-by-step explanation:

Recall that all angles in a triangle add up to 180º. Also recall that the side opposite largest angle is the longest side, and vice versa for the side opposite the smallest angle.

Help Q-Q 7/10c =4 1/5
shepuryov [24]

\huge\mathfrak\green{answer}

= q -   \frac{q7}{10} c =  \frac{41}{5}

\red{multiply}

= q -  \frac{cq7}{10} =  \frac{41}{5}

\red{subtract \: q \: from \: both \: sides}

= q -  \frac{cq7}{10}  - q =  \frac{41}{5} - q

\red{now \: simplify}

=  -  \frac{cq7}{10}  =  \frac{41}{5}  - q

\red{multiply \: 10 \: both \: sides}

= 10( -  \frac{cq7}{10} ) = 10. \frac{41}{5}  - 10q

\red{simplify}

=  - cq7 = 82 - 10q

\red{now \: divide}

=  \frac{ - cq7}{ - q7}  -  \frac{82}{ - q7}  -  \frac{10q}{ - q7}

\red{simplify}

= c =   - \frac{82 - 10q}{q7} (q≠0)

Brainliest? :) (I'd really appreciate if you mark me as brainliest)
