Answer:
<h2>x = 12</h2>
Step-by-step explanation:
ΔADC and ΔCDB are similar (AA). Therefore the sides are in proportion:

We have AD = 16, DC = x, DB = 9. Substitute:
<em>cross multiply</em>

The car moved 175.84 cm in one revolution
The car has moved 17584 cm in 100 revolutions
<em><u>Solution:</u></em>
Given that car wheel is 56 cm in diameter
diameter = 56 cm
To find: distance traveled in one revolution of wheel
Usually wheel is of circular shape
one revolution of wheel = circumference of circle
<em><u>The circumference of circle is given as:</u></em>

We know that,
diameter = 2(radius)

<em><u>So the circumference becomes:</u></em>

substitute
= 3.14 and d = 56 cm

Thus the car moved 175.84 cm in one revolution
<em><u>B. How far does it go in 100 revolutions</u></em>
Distance covered in 100 revolutions = 100 x Distance covered in 1 revolution

Thus the car has moved 17584 cm in 100 revolutions
Answer: 8.1
Step-by-step explanation: How you convert a mixed number into a decimal is taking the whole number (not the fraction part) and putting it in front of the decimal, then you get the fraction's denominator to 10 multiply if needed, then you take the fractions top number and put it after the decimal, Now your converted!
