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 numbers are 31 and 15. Add to get a sum of 46, and subtract to get a difference of 16.
Step-by-step explanation:
Answer:
(-11, 1)
Step-by-step explanation:
x-values are horizontal and y-values are vertical
so add -4 to -7 to get -11
add 0 to 1 to get 1
new point is at (-11,1)
Answer:
$60
Step-by-step explanation:
This is because 400 times 0.03 is 12 and 12 times 5 is 60
<h3><em><u>The equation to find the number of hours for which the total cost will be the same for the two services is:</u></em></h3><h3>12 + 5h = 18 + 3h</h3>
<em><u>Solution:</u></em>
Let "h" be the number of hours
Given that,
<em><u>Derrick's Dog Sitting charges $12 plus $5 per hour</u></em>
Cost : 12 + 5(number of hours )
Cost : 12 + 5h ---------- eqn 1
<em><u>Darlene's Dog Sitting charges $18 plus $3 per hour</u></em>
Cost: 18 + 3(number of hours)
Cost: 18 + 3h ---------- eqn 1
<em><u>For eqn 1 = eqn 2, the number of hours for the total cost will be the same for the two services</u></em>
Therefore,
12 + 5h = 18 + 3h
Thus option A is correct
