Answer: 5 2/3 inches
Step-by-step explanation:
From the question, we are informed that the scale drawing of an airplane is:
1 inch = 3 meters.
Since the length of the actual plane is 17 meters, the length of the plane in the scale drawing will then be:
= 17/3
= 5 2/3 inches
Answer: When x=2 and z = 1, then the value of y =4.
Step-by-step explanation:
Given: y varies directly as x and z i.e. 
(i) , where k is the proportionality constant.
Put Y=40 ,x =5 and z = 4, then we get

Required equation:
[Put value of k in (i)]
Now put x=2 and z = 1, then we get

Hence, when x=2 and z = 1, then the value of y =4.
<em>If a rectangular prism has a volume of 470.40 cm</em><span><em>³, and the length and width is equal to 6.4 and 9.8, we will find the height by using some inverse operations. We will use the variable h to represent height</em>
<em>Length x Width x Height = Volume</em>
<em>6.4 cm • 9.8 cm `• h = 470.40</em>
<em>470.40 ÷ (9.8 x 6.4)</em>
<em> = 470.40 ÷ 62.72</em>
<em> = 7.5</em>
<em>Check Answer:</em>
</span><em>Length x Width x Height = Volume</em>
<em>6.4 cm • 9.8 cm `• 7.5 = 470.40</em>
<u>Answer: 7.5 cm</u>
