Answer:
The dimensions of the tire are 190/75-15.
The first number is the width of tire in mm, here is 190 mm
The second number is ratio between sidewall and width of tire in %, here is 75%
The third number is diameter of wheel in inch, here is 15 inch or 15 x 25.4 = 381 mm
Then, we have:
1. The width of the tire is the first number: 190 (mm)
2. The length of the side wall = width x ratio = 190 x 75/100 = 142.5 mm
or 142.5 /25.4 = 5.61 inch
3. The diameter of the whole tire:
D = diameter of wheel + sidewall x 2
= 381 + 142.5 x 2
= 666 mm or 666/25.4 = 26.22 inch
Hope this helps!

ANSWER
The correct answer is C
EXPLANATION
We want to find the quotient:
We multiply by the reciprocal of the second fraction:
We cancel out the common factors to obtain:
We multiply to get
This simplifies to :
The correct answer is C
A)
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, 5.1) and (-1, -0.5). Substitute:
Therefore we have:
Put the coordinates of the point (-1, -0.5) ot the equation:
<em>multiply both sides by 2</em>
<em>add to both sides</em>
<em>divide both sides by 2</em>
Answer:
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:
Therefore we have:
Put the coordinates of the point (-2, 3) to the equation of a line:
<em>subtract from both sides</em>
