Answer:

13.5 feets

1 inch

Step-by-step explanation:

Given :

Blueprint length (in.) __2 4 6 8 10 12

Actual length (ft) _____3 6 9 12 15 18

From the data:

Blueprint : actual

2 in : 3 feets

Length of wall on blueprint = 9 inches

Actual length of wall :

2 inches = 3feets

9 inches = x

Cross multiply

2x = 27

x = 27 /2

x = 13.5 feets

B.)

For actual width = 1.5 feets

2 inches = 3feets

x = 1.5 feets

3x = 2 * 1.5

3x = 3

x = 3/3

x = 1 inch

at maximum speed , an airplane travels 1680 miles against the wind in 5 hours flying with the wind , the plane can travel the sa

Westkost [7]

X = velocity of plane
y = velocity of wind

x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]

Adding (1) and (2) to eliminate y gives

2x = 756
x = 378 mph is the speed of the plane with no wind.

2) The two rectangles shown are similar.

Citrus2011 [14]

Answer:

$6\ cm$

Step-by-step explanation:

First Rectangle:

$length(l_1)=24\ cm\\\\Width(b_1)=9\ cm$

Second Rectangle:

$length(l_2)=16\ cm\\\\Let\ Width=b_2\ cm$

$Since\ these\ two\ rectangles\ are\ similar\\\\\frac{l_2}{l_1}=\frac{b_2}{b_1}\\\\\frac{16}{24}=\frac{b_2}{9}\\\\16\times 9=24\times b_2\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ cross\ multiplication\\\\b_2=\frac{16\times 9}{24}\\\\b_2=6\ cm$
