Answer:
128cm
Step-by-step explanation:
Your Welcome :)
PV = nRT
nR nR
PV/nR = T
C = Wtc/1000
1000C = Wtc
tc tc
1000C/tc = W
You can tell when a number is rational because it can be represented as a fraction. Yes it is a rational number.
Given:
Two rectangles are similar.
Length of first rectangle = 18 cm
Width of first rectangle = 6 cm
Width of second rectangle = 2 cm
To find:
The length of the second rectangle.
Solution:
We know that the corresponding sides of similar triangles are proportional. So,

Let x be the length of the second rectangle. Then,




Therefore, the length of the second rectangle is 6 cm.
Answer:
n = 125
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Number n is 25 less than 120% of itself. What is the value of n?
25 less than 120% of itself can be represented as: <u>1.2n - 25</u>
n = 1.2n - 25
<u>Step 2: Add Subtract 1.2 from both sides</u>
n - 1.2n = 1.2n - 25 - 1.2n
-0.2n = -25
<u>Step 3: Divide both sides by -0.2</u>
-0.2n / -0.2 = -25 / -0.2
<em>n = 125</em>
