Answer:
<em>12^2 + x^2 = 13^2</em>
Step-by-step explanation:
The student's error was that he didn't use the Pythagorean Theorem correctly
According to the Pythagorean Theorem, <em>a^2 + b^2 = c^2</em>, where c represents the hypotenuse
However, the student replaced <em>c</em> with <em>x</em>, which isn't the hypotenuse
The hypotenuse is 13, so <em>c</em> should be 13, not <em>x</em>
Answer:
Step-by-step explanation:
In order to determine the number of wax cubes needed to make the candle, we divide the volume of the pyramid by the volume of the cube. That is,
number of wax = volume of mold / volume of wax
The formulas are,
number of wax = (1/3)Ah / s³
Where A is the area of the base, in this case 9 cm x 9 cm which is equal to 81 cm². Substituting the known values from the given above,
number of wax = (1/3)(81 cm²)(10 cm) / (4 cm)³ = 4.21
Thus, approximate number of wax should be 4.21. If we are to round this off to the nearest whole number, we will get 5 (considering that we want rather to have excess than missing items)
1/3 miles
You can get this by multiplying the two numbers together which will give you 10/30. That can then be simplified.
