The given figure is a sphere :
_____________________________
Answer:
6
Step-by-step explanation:
96÷5=19.2
<u>96÷6=16</u>
96÷10=9.6
96÷14=6.857142~
<span>12(x-2)<24
Multiply the number outside the parenthesis with the numbers inside the parenthesis
12x-24<24
Add 24 to both sides
12x<48
Divide both sides by 12 so that x is the only thing remaining on the left side is the x variable.
Final Answer: x<4</span>
Answer:
$13.00
Step-by-step explanation:
Let f represent the price per foot of pasture fence, and p represent the price per foot of picket fence. The two purchases can be written in equation form as ...
2000f + 450p = 12850
700f +300p = 6350
Using Cramer's rule, we can find the value of the picket fence as ...
p = (12850·700 -6350·2000)/(450·700 -300·2000) = -3705000/-285000
p = 13
The cost per foot of picket fence is $13.00.

<em>Cramer's Rule and Vedic math</em>
The above equation for p is a summary of the math you would be doing if you were to solve the equations by eliminating f. Cramer formulates it in terms of determinants of the coefficients in the equations. Practitioners of Vedic math formulate it in terms of X-pattern combinations of the coefficients in much the same way as finding a determinant. For the equations ...
The solutions are ...
∆ = bd -ea
x = (bf -ec)/∆
y = (cd -fa)/∆ . . . . . this is the equation we used above
__
If you do a rigorous comparison of this formula with that of Cramer's rule, you find the signs of numerator and denominator are reversed. That has no net effect on the solution, but it makes the X pattern of products easier to remember for practitioners of Vedic math.
