What is the missing reason in the proof?Given: ∠ABC is a right angle, ∠DBC is a straight angleProve: ∠ABC ≅ ∠ABDdefinition of an
horsena [70]

For a better understanding of the solution provided here please find the relevant diagram drawn as per given information in the file attached.

As given, \angle ABC=90^{\circ}. Also, it is given that \angle DBC is a straight angle. Therefore, \angle DBC=180^{\circ}.

As can be clearly seen from the diagram, if \angle DBC=180^{\circ} and \angle ABC=90^{\circ}, then:

\angle ABD=\angle DBC-\angle ABC=180^{\circ}-90^{\circ}=90^{\circ}

Therefore, \angle ABD\cong\angle ABC

Hence Proved.

When factored completely, the expression p^4 - 81 is equivalent to
Paha777 [63]
P⁴ - 81
p⁴ + 9p² - 9p² - 81
p²(p²) + p²(9) - 9(p²) - 9(9)
p²(p² + 9) - 9(p² + 9)
(p² - 9)(p² + 9)
(p² + 3p - 3p - 9)(p² + 9)
(p(p) + p(3) - 3(p) - 3(3))(p² + 9)
(p(p + 3) - 3(p + 3))(p² + 9)
(p - 3)(p + 3)(p² + 9)

The answer is (3).

Maxwell House Coffee contains 13% Columbian coffee beans by volume while
user100 [1]

<em>x</em> kg of Maxwell House coffee contains 0.13<em>x</em> kg of Columbian beans.

<em>y</em> kg of Folgers contains 0.21<em>y</em> kg of beans.

You want a mixture weighing 70 kg, so

<em>x</em> + <em>y</em> = 70

You also want this blend to consist of 19% Columbian beans, or 0.19 (70 kg) = 13.3 kg, so

0.13<em>x</em> + 0.21<em>y</em> = 13.3

Solve for <em>x</em> and <em>y</em> :

<em>x</em> + <em>y</em> = 70   ===>   <em>y</em> = 70 - <em>x</em>

0.13<em>x</em> + 0.21<em>y</em> = 13.3   ===>   0.13<em>x</em> + 0.21 (70 - <em>x</em>) = 13.3

0.13<em>x</em> + 14.7 - 0.21<em>x</em> = 13.3

14.7 - 13.3 = 0.21<em>x</em> - 0.13<em>x</em>

1.4 = 0.08<em>x</em>

<em>x</em> = 17.5

<em>y</em> = 52.5
