<h3>Answer:  11.2 inches</h3>

Work Shown:

(real height)/(scale height) = (real length)/(scale length)

(10 feet)/(8 inches) = (14 feet)/(x inches)

10/8 = 14/x

10x = 112

x = 112/10

x = 11.2 inches

avanturin [10]

Answer:  2.28%

Step-by-step explanation:

Given: An airport find that at the present time, the mean noise level is 103 decibels and the standard deviation is 5.4 decibels.

The distribution of noise levels(x) for all jets during takeoff over the neighborhood has a normal distribution.

The probability that jets have a noise level less than 92.2 decibels when taking off over this neighborhood will be :-

P(X

Hence, the percent of these jets have a noise level less than 92.2 decibels when taking off over this neighborhood = 2.28%

Given a right triangle with legs a, b and hypotenuse c, solve for a if b= 20 and c= 29
pantera1 [17]

Answer:

C) 21

Step-by-step explanation:

a² + 20² = 29²       Use Pythagorean Theorem to solve for a

a² + 400 = 841       Solve for the exponents

     - 400 - 400      Subtract 400 from both sides

a² = 441                  Take the square root of both sides

a = 21
