         Statement                                              Reason

1. ΔABC is a right triangle, with a     1. Given

right angle at ∠C

2. Draw an altitude from point C     2. From a point not on a line, exactly                    

to AB               one perpendicular can be drawn through the point to the line

3. ∠CDB and ∠CDA are right          3. Definition of altitude

angles

4. ∠BCA  ≅ ∠BDC                            4. All right angles are congruent

5. ∠B  ≅ ∠B                                      5. Reflexive\:Property

6. ΔCBA ~ ΔDBC                             6.

A company has designed a new cereal box. This new box has a height of 25 cm, a width
GuDViN [60]

Answer:

$0.13 to produce each box.

Step-by-step explanation:

S= ph+2b

p= 12.5+2.5+12.5+2.5=30

h=25

b= 12.5x2.5=31.25

S= (30)(25) +2 (31.25)

S= 812.5cm^{2}

812.5 x 0.00016= 0.13

If there is 54% increase on a $54 item, then how much is the new cost for next year? Round to the nearest penny.
Mariulka [41]

Answer: $83.16

Step-by-step explanation:

     This means that next year the item will cost 154% of what it is now.

154% / 100 = 1.54

$54 * 1.54 = $83.16

                    Next year the item will cost $83.16.

The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room
lozanna [386]

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.

Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet

Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet

Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet
