R and 81 are common factors so add them together and you get 9r;then your equation is 9r+11=29.After that you subtract 11 from 29 and then the equation is 9r=18.Then you divide 9 from 18 so you get r=2.
Let x be the speed of the first car in miles per hour. After 12 hours it will have gone 12x miles. The other car, driving east, has speed x+ 4. After 12 hours it will have gone 12(x+ 4) miles. Again by the Pythagorean theorem,
(12x)^2+(12(x+4)^2=600^2. Solve that equation for x.
Answer:
B - <em>∠b and ∠f</em>
Step-by-step explanation:
Corresponding angles are the angles in matching corners of the intersections in the traversal. Since <em>∠b</em> and <em>∠f</em> are in the same position relative to the intersection, they are corresponding.

Step-by-step explanation:
Remark
At the beginning of the experiment the time (in minutes) is zero. That means that the -0.3*m term disappears. The point of the remark is that the candle's height to begin with is 16.4 cm
Given
m = 29 min
Solution
H = - 0.3*m + 16.4
H = - 0.3*29 + 16.4
H = - 8.7 + 16.4
H = 8.8 cm
