The actual fountain is 6 ft tall.....1 ft = 12 inches...so 6 ft = (12 * 6) = 72 inches
72/27 = 2 2/3....u have a scale factor of 2 2/3 (or 8/3)
so the diameter will be :
63 * 2 2/3 =
63 * 8/3 =
504/3 =
168 inches.....12 inches = 1 ft...so 168 inches = (168/12) = 14 ft <==
Answer:
79.986
Step-by-step explanation:
Let A represent isotope ⁷⁹Br
Let B represent isotope ⁸¹Br
From the question given above, the following data were obtained:
For Isotope A (⁷⁹Br):
Mass of A = 79
Abundance of A (A%) = 50.69%
For isotope B (⁸¹Br):
Mass of B = 81
Abundance of B (B%) = 49.31%
Relative atomic mass of Br =?
The relative atomic mass (RAM) of Br can be obtained as follow:
RAM = [(Mass of A × A%) /100] + [(Mass of B × B%) /100]
= [(79 × 50.69) /100] + [(81 × 49.31) /100]
= 40.0451 + 39.9411
= 79.986 amu
Thus, the relative atomic mass of Br is 79.986
C. (4,-7)
y=2x-15
-7=2(4)-15
4x+3y=-5
4(4)+3(-21)=-5
Answer:
Step-by-step explanation:
The sum of 83 and a number would be as an expression, where 
is "said number".
Answer:
x=9
Step-by-step explanation:
4(x – 2) = 3x + 1
Distribute 4x-8 = 3x+1
Subtract 3x from each side
4x -8-3x = 3x-3x + 1
x-8 =1
Add 8 to each side
x-8+8 = 1+8
x=9
