A window is 21 inches wide, and its perimeter is 112 inches. What is the length of the window?
Kazeer [188]

Answer:

The length of the window is 35 inches.  

Step-by-step explanation:

Perimeter of an object can be found using the general formula:  P = 2W + 2L, where P = perimeter, W = width and L= length.  Since both the width and perimeter of the window are given, we can plug these values into the formula to solve for the missing variable 'L':  112 = 2(21) + 2L, or 112 = 42 + 2L.  We can then use inverse (opposite) operations to isolate the variable and solve.  Whatever we do to one side of the equation, we do to the other.  We will start by subtracting 42 from each side:  112 - 42 = 42 - 42 + 2L or 70 = 2L.  Next, we divide both sides by 2 to solve for L:  70/2 = 2L/2 or L = 35.  So, the final length of the window is 35 inches.

Julia is designing a frame for a client. She wants to prove to her client that m∠AGE ≅ m∠FHD in her sketch. What is the missing
katen-ka-za [31]

The missing justification in Julia's angle proof is; Corresponding Angles Theorem

<h3>What is the angle theorem used?</h3>

We know that m∠AGE ≅ m∠HGB because they have congruent angles and are vertical angles.

Similarly, m∠HGB ≅ m∠CHE are alternate interior angles because two congruent angles on the inner side of the parallel lines are formed by a transversal.

In the diagram, m∠AGE ≅ m∠CHE would have to be corresponding Angles Theorem because parallel lines cut by a transversal would create congruent corresponding angles. That means a pair of angles on the same side of one of two lines that is cut by a transversal and on the same side of the transversal.

What is the total area of the glass in the pyramid arena? Explain how you got the answer please.
Blababa [14]

Answer: 888,000

Step-by-step explanation:

Base: 600 x 600 = 360,000

600 x 440 x 2 (there is 4 triangles and 2 makes 1 square. So there is 2 pairs so times 2)= 528,000

360,000 + 528,000= 888,000

Which expression is undefined?
Mkey [24]

Answer:

D: \frac{3}{(6-6)}

Step-by-step explanation:

Option A equates to -\frac{0}{2}=0

Option B equates to \frac{(-4+0)}{8}=\frac{-4}{8}=-\frac{1}{2}

Option C equates to 0\div11 =0

Option D equates to \frac{3}{(6-6)}=\frac{3}{0} which cannot be defined as division by 0 is impossible
