Answer:
<em>The actual width of the hair is 20 / 150 = 0.13 mm</em>
Step-by-step explanation:
<u>Scaling</u>
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.
The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.
The hair can be seen 2 cm wide in the photograph.
Converting to millimeters, 2 cm = 2*10 = 20 millimeters.
The actual width of the hair is 20 / 150 = 0.13 mm
The equation would be
12 ÷ 1/3 =
12 x 3/1 =
12 x 3 =
36 miles
Answer:
The length of the rectangle is 30 feet.
Step-by-step explanation:
Because the equation for area is length times width, you would have to set the two equations to seventy and multiply them.
<em> (x+5) (x+2) = 70</em>
<em> </em><em>2x + 10 = 70</em>
Then, you would have to subtract ten from both sides, cancelling it from the left side.
<em> 2x = 60</em>
<em />
Then do the opposite and divide sixty by two, therefore getting a length of thirty feet.
