<span>ralph = r
sara = s
ralph is TODAY, 3 times older, so if sara is "s" old, ralph is 3s
r = 3s
in 6 years, ralph will be 2 times as old as sara THEN,
in 6 years ralph will be TODAY's age plus 6, so r + 6
so if sara is "s" old, r+ 6 = 2s
r + 6 = 2s</span>
I made a number line and drew it out -6,-5,-4,-3,-2,-1,0,1,2 and i counted how many i had to move over to get to 2 from -6 and i got 8
The surface area would be 26.5487 m².
The surface area of a cylinder is equal to the area of the circles at both ends, added to the area of the rectangular portion in the middle. The rectangle in the middle has a width equal to the circumference of the circle and a length equal to the height of the cylinder.
The circumference of a circle is given by C = πd, and the area of the circles is given by A=πr².
Since the height is in meters, we will convert it to cm. 3.5 m = 350 cm.
The diameter is 190 cm, so the radius is 190/2 = 95 cm.
This gives us:
SA = 3.14(190)(350)+2(3.14)(95)²
= 208810 + 56677 = 265487 cm² = 26.5487 m²
Answer:
Collision coverage pays for damage to your car resulting from a collision with another car, an object, such as a tree or telephone pole, or as a result of flipping over (note that collisions with deer are covered under comprehensive). It also covers damage caused by potholes.
Hope this helped. :)
