Answer:
Answer below, however this question is worded weirdly
Step-by-step explanation:
x(x - 0.37 ) = 12.6
simplify the equation
x^2 - 0.37x = 12.6
x^2 - 0.37x - 12.6 = 0
Answer:
Put one point on (0, -4)
Put the other on (3, -2)
Step-by-step explanation:
That's how graphing works
Yes the treasury can determine whether the gold bar is
really weighing 500 ounces.
We can use the equation:
7 x + 11 y = 500
where x is the amount of the 7 ounce weights while y is
the amount of 11 ounce weights.
We know that x and y should be whole numbers therefore
this is solved through trial and error.
By trial and error I got:
x = 7 and y = 41
<span>
So that;</span>
7 * 7 + 11 * 41 = 500
49 + 451 = 500
500 = 500
<span>Hence they can use 41 11-ounce weights and 7 7-ounce
weights to test</span>
Answer:
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .
