Answer:

small: 6.25

large: 18.25

Step-by-step explanation:

Set the large boxes as x and the small boxes as y (The weight is the constant).

3x+5y=86

6x+2y=122

Now just solve the systems of equations using either substitution or elimination.

-6x-10y=-172 multiply the whole equation by -2 to eliminate

6x+2y=122, add the equations

-8y=-50

y= 6.25

Plug in y either equation:

3x+5(6.25)=86

3x=86-31.25

3x=54.75

x=18.25

Each small box weighs 6.25 kilograms, each large box weighs 18.25 kilograms, to check plug in the values to the other equation to see if they add up correctly.

Point F(-17,8) is rotated 180° about the origin what are the coordinates of image f?
dlinn [17]

Answer:

F'(17, - 8 )

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y ), thus

F(- 17, 8 ) → F'(17, - 8 )

What is 7.8 × 105 m/h in kilometers per day? A. 3.24 × 1010 km/day B. 3.24 × 108 km/day C. 1.872 × 106 km/day D. 1.872 × 104 km/
damaskus [11]
The comparison may be done by the dimensional analysis and the proper conversion factor. That is,
   (7.8 x 10^5 m/h) x (1 km / 1000 m) x (24 h / 1 day) = 18720 km / day
The scientific notation of the answer is 1.872 x 10^4 km/day. Thus, the answer is letter D.

What is the quotient? 28/25,704
ankoles [38]

Answer:

  see the attached

Step-by-step explanation:

The fraction reduces to 1/918, which has an equivalent decimal fraction with a 48-digit repeat. The first 9 significant digits of that fraction are shown in the attachment.

\dfrac{28}{25704}=\dfrac{1}{918}\\\\=0.0\overline{010893246187363834422657952069716775599128540305}

Identify the sets that contain 2 as an element. (Check all that apply.)Check All That Apply{2, 3, 4, 5, ...}{2, 3, 4, 5, ...}{0,
Lady bird [3.3K]

Question:

Identify the sets that contain 2 as an element. (Check all that apply.)

A.\ \{2, 3, 4, 5, ...\}

B.\ \{0, 1, 4, 9, ...\}

C.\ \{2, \{2\} \}

D.\ \{\{2\}, \{\{2\}\}\}

E.\ \{\{2\}, \{2, \{2\}\}\}

F.\ \{\{\{2\}\}\}

Answer:

A.\ \{2, 3, 4, 5, ...\}

C.\ \{2, \{2\} \}

Step-by-step explanation:

Required

For which of the options is 2 an element

A.\ \{2, 3, 4, 5, ...\}

The elements of this set starts from 2, then 3 and continues as thus.

Hence: 2 is an element

B.\ \{0, 1, 4, 9, ...\}

From the given elements in the above set, 2 is not listed.

Hence: 2 is not an element of this set

C.\ \{2, \{2\} \}

Here, 2 is listed as an element, 2 is also listed as a subset.

Since 2 is listed as an element, then 2 is an element of the set.

D.\ \{\{2\}, \{\{2\}\}\}

Here, 2 is listed as a subset of {2} and also as a subset of subset of {{2}}.

Since 2 is not listed as an element itself, then 2 is not an element of the set.

E.\ \{\{2\}, \{2, \{2\}\}\}

Here, 2 is listed as a subset of {2} and also as a subset of subset of {2,{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set

F.\ \{\{\{2\}\}\}

Here, 2 is listed as a subset of subset of {{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set
