The perimeter of an equilateral triangle is 83 inches. If the length of each side is (2x -3), find the value of x.
Minchanka [31]

Answer:

x = 15 \frac{1}{3}

Step-by-step explanation:

Equilateral triangles have 3 equal sides.

Thus, perimeter of triangle

= 3(2x -3)

= 3(2x) +3(-3) <em>(</em><em>expand</em><em>)</em>

= (6x -9) inches

Given that the perimeter is 83 inches,

6x -9= 83

6x= 83 +9 <em>(</em><em>+</em><em>9</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

6x= 92

x = 15 \frac{1}{3}

Write an equation in point-slope form for the line through the given point with the given slope.
Paul [167]

Answer:

C.) \displaystyle y - 6 = \frac{3}{4}(x + 4)

Explanation:

In the Point-Slope Formula [y - y₁ = m(x - x₁)], all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

Calculate the amount of heat (in kJ) released when 3.5 mol CH4 react. 4() + 22() → 2() + 22() + 890
In-s [12.5K]

The amount of heat (in KJ) released when 3.5 moles of CH₄ react is 3115 KJ

<h3>Balanced equation</h3>

CH₄ + 2O₂ -> CO₂ + 2H₂O ΔH = 890 KJ

From the balanced equation above,

1 mole of CH₄ reacted to release 890 KJ of heat energy.

<h3>How to determine the heat energy released by 3.5 moles of CH₄</h3>

From the balanced equation above,

1 mole of CH₄ reacted to release 890 KJ of heat energy

Therefore,

3.5 moles of CH₄ will react ro release = 3.5 × 890 = 3115 KJ of heat energy

Thus, 3115 KJ of heat energy were released from the reaction

A sample of 1500 computer chips revealed that 55% of the chips do not fail in the first 1000 hours of their use. The company's p
Anvisha [2.4K]

Answer:

1.28

Step-by-step explanation:

Given that a sample of 1500 computer chips revealed that 55% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 53% of the chips do not fail in the first 1000 hours of their use.

H_0: p = 0.53\\\\H_a: p \neq 0.53

(Two tailed test for testing sample proportion with population proportion)

Std error of proportion assuming p = 0.53 is

\sqrt{0.53*0.47/1000} \\=0.0157

p difference = 0.02

Z= test statistic = p diff/std error = 1.2775~1.28
