Step-by-step explanation:
- In a right triangle, if ∠B is 45°, then ∠C is too.
-- Since ∠B and ∠C are equal, the sides opposite them
are equal too. This is an isosceles right triangle. Its legs
are equal.
-- (The hypotenuse)² = (one leg)² + (the other leg)²
= (12-ft)² + (12-ft)²
= (144 x 2)
The hypotenuse = √(144 x 2) = 12√2 .

Answer: x=68/11 and y=-72/11
Steps:
2(x+4y=-20)
2x+8y=-40
2x - 3y = 32
- 2x + 8y = -40
-11y=72
y=-72/11
x + 4(-72/11) = -20
x - 288/11 = -20
x=68/11
A = 3.5
b = 3.5
c = 2.5
d = 2.85
e = 2.6
The two unit rates that are equal are a and b
28 per 8 salads and 42 per 12 steaks have equal unit rates.
Answer:
5.524 in 2 significant figures rounding the value to 2 non zero numbers.
<em>5</em><em>.</em><em>5</em><em>2</em><em>4</em><em> </em><em>=</em><em> </em><em>5</em><em>.</em><em>5</em><em> </em><em>(</em><em>2</em><em> </em><em>significant</em><em> figures</em><em>)</em>
The perimeter of question 50 would be 44 inches (not square inches).
