Answer:

Total volume of the figure = 1067 cm³

Step-by-step explanation:

Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid

Volume of the rectangular prism = Length × Width × Height

                                                      = 10 × 10 × 7

                                                       = 700 cm³

Volume of the square pyramid = \frac{1}{3}(\text{Area of the base})\times (\text{height})

                                                   = \frac{1}{3}(\text{Side})^2 × height

                                                   = \frac{1}{3}(10)^2(18-7)

                                                   = 366.67 cm³

Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³

                                                                                          ≈ 1067 cm³

The sum of two numbers is 67. The larger number is 4 more than 2 times the smaller. What are the two numbers?
Paha777 [63]
X,y - two numbers (x > y)

(1)    x + y = 67 ⇒ x = 67 - y
(2)    x - 4 = 2y

subtitute (1) to (2)

67 - y - 4 = 2y
63 - y = 2y    |add y to both sides
63 = 3y    |divide both sides by 3
y = 21

subtitute the value of y to (1)

x = 67 - 21 = 46

Answer: 21 and 46.

Please help<br><br>numbers 42, 43, 44
Aleks [24]
<h3>Answer:</h3>

42.  29°

43.  3x³ +2x² -3x +10

44.  20a² +68a

<h3>Step-by-step explanation:</h3>

42.  The right-angle corner tells you the two marked angles are complementary — they sum to 90°.

  (-3x +20)° + (-2x +55)° = 90°

  -5x +75 = 90 . . . . . . . . . . collect terms, divide by °

  -5x = 15 . . . . . . . . . . . . . . . subtract 75

  x = -3 . . . . . divide by the coefficient of x

The angle of interest is (-3x+20)°. Filling in the found value for x, we have ...

  (-3·(-3) +20)° = 29° = m∠BDC

___

43.  The distributive property is useful for multiplying polynomials.

  (x +2)(3x² -4x +5) = x(3x² -4x +5) +2(3x² -4x +5)

  = 3x³ -4x² +5x +6x² -8x +10 . . . . . eliminate parentheses

  = 3x³ +2x² -3x +10

___

44.  Area is the product of length and width, so this becomes a problem in multiplying polynomials.

  area = (5a +17)(4a) = 20a² +68a . . . . area in square feet
