20 + G = 64
20 is the known constant and is a known variable and is a addend to the score while G is another addend but we just don’t know the value so when you put the equation together the 20 would stand for the known addend and the G would stand for the unknown addend which both equal to 64z

What is the length or area of shaded part?

Ivanshal [37]

Answer:

29.7345 square units

Step-by-step explanation:

Area of the shaded part = Area of the rectangle - Area of the quarter circle

Area of the rectangle = Length × Width = 10 × 8 = 80 square units

Area of the quarter circle = $\frac{1}{4}$ × π × r² (r for radius) = 0.25 × π × 8² = 50.2655 square units (answer rounded up to four decimal places)

Area of the shaded part = 80 square units - 50.2655 square units = 29.7345 square units

Joseph squares a number and subtracts 8 from the answer. He then divides this result by 7. Finally he adds 12 and the result is

ivanzaharov [21]

Let the number be X, then we find
$( {x}^{2} - 8) \div 7 + 12 = 20$
$( {x}^{2} - 8) \div 7 = 8$
$( {x}^{2} - 8) = 56$
${x}^{2} = 64$
$x = \sqrt{64} \: \: \: \: \: x = - \sqrt{64}$
$x = 8 \: \: \: \: \: x = - 8$
