i know you need this quick so i made it short, good luck.
Answer:
Not similar
Step-by-step explanation:
18 is the least common denominator of all the fractions, so you can eliminate fractions by multiplying the equation by 18.
(4.5*18)x +((7/9)*18)x + (2 1/3)*18 + ((1/6)*18)x = (5 1/18)*18
81x +14x +42 +3x = 91 . . . . . simplify
Collect terms.
98x + 42 = 91
98x = 49 . . . . . . . . . subtract 42
x = 49/98 = 1/2
The solution is x = 1/2.
_____
You can also do the arithmetic with mixed numbers and fractions. The usual methods apply.
(4.5 + 7/9 + 1/6)x + 2 1/3 = 5 1/18
(49/9)x + 7/3 = 91/18
(49/9)x = 49/18 . . . . . . . subtract 7/3
x = (9/49)(49/18) = 9/18 = 1/2 . . . . . multiply by 9/49
This can be a little more tedious than the method above, but it works and it will give you the right answer. A calculator that works with fractions can make this solution as easy as the other one.
Answer:
753.98 square feet
Step-by-step explanation:
Diameter of the fountain =8 inches
- Therefore Radius of the fountain, =8/2=4 Inches
The flower garden extends 12 feet beyond the fountain, therefore:
- Radius of the flower garden=4+12 =16 Inches
Let the fountain be the inner circle with radius r and the larger circle which includes the garden have a radius, R. Then:
Area of the flower garden
