If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.
Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.
So, together, they paint the following fraction of the wall in one hour:
.
At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint
i.e. the whole wall
It is actually not 28 because the volume of a cylinder is: pi r^2 x h which in this case is pi x 36 x 4 which equals 452.39 rounded up
Answer: The dimensions of the garden would be 18 feet and 24 feet.
Step-by-step explanation:
Let the width of garden be 'x'.
Let the length of garden be 
Since there is 3 foot wide walkway surrounds the outside the garden.
Area of walkway = 288 square feet
So, According to question, it becomes,
Width = 18+6 =24 feet
Hence, the dimensions of the garden would be 18 feet and 24 feet.
Answer:
35 for perimeter of b
122.5 for perimeter of a
Step-by-step explanation:
To find the perimeter, you add all of the values of the outside of the shape together. Since 12+9+9+5 = 35, the answer is 35.
Okay, so what you have to do is set up a proportion for a to b. To do that, you have to have a fraction where a is the numerator and b is the denominator. 7/2 equals x/35. Then cross multiply
7*35 = 2x
x = 122.5 :)
