Answer: 5 people will clean 20 rooms in 1 hour.

Step-by-step explanation:

45 minutes is 45/60 = 0.75 hours

The two people invested 2(0.75) = 1.50 man•hrs to clean 6 rooms

each room took 1.5/6  = 0.25 man•hr/room

To clean 20 rooms will take 20(0.25) = 5 man•hrs

5 man•hrs/5 people = 1 hr.

Which additional facts prove that RST and<br> WXY are congruent? (Geometry)
alexandr402 [8]

Answer:

Option C

Step-by-step explanation:

In the given triangles ΔRSW and ΔWXY,

m(∠S) = m(∠X) = 60° [Given]

Properties of congruence of two triangles applicable in this question,

SAS or ASA

For the congruence of two triangles by the property SAS,

"Two corresponding sides and the included angle should be congruent"

RS ≅ WX, ST ≅ XY and ∠S ≅ ∠X

Which is not given in any option.

For the congruence of two triangles by the property ASA,

"Two consecutive angles and the side having these angles should be congruent"

∠R ≅ ∠W, ∠S ≅ ∠X and RS ≅ XY

Option C will be the correct option.

Use the hundredths grid to answer the question.
professor190 [17]

The question is an illustration of multiplication model.

The multiplication model is: \mathbf{0.90 \times 0.10 =0.09}

From the figure, the shaded portions are:

\mathbf{Green = \frac{90}{100}}

\mathbf{Orange = \frac{10}{100}}

So, the multiplication model represents:

\mathbf{Model =Green \times Orange}

This gives

\mathbf{Model =\frac{90}{100} \times \frac{10}{100}}

Express as decimal

\mathbf{Model =0.90 \times 0.10}

\mathbf{Model =0.09}

Hence, the multiplication model is:

\mathbf{0.90 \times 0.10 =0.09}

Two distinct planes __________ intersect in a pair of lines
hammer [34]
If the planes are parallel to one another then they will never intersect (assuming they are distinct planes as the question states).

Otherwise they will intersect along a single line.

Therefore the answer is NEVER - they can never intersect in a pair of lines.
