Answers

Answer:  the left side is balanced with the right side

Step-by-step explanation:

Left side:

1 barrel (located at 2) is 1 unit from the fulcrum (triangle)         →    1(1) = 1

2 barrels (located at 1) are 2 units from the fulcrum (triangle)  →  2(2) = 4

1 barrel (located at 0) is 3 units from the fulcrum (triangle)       →  1(3) = 3    

                                                                                                       Total = 8

Right side:

1 barrel (located at 6) is 3 units from the fulcrum (triangle)       →    1(3) = 3

1 barrel (located at 8) is 5 units from the fulcrum (triangle)       →  1(5) = 5    

                                                                                                       Total = 8

The distribution of the weight on the left side equals the distribution of weight on the right side so the beam is balanced.

If the sales tax in Texas is 8.25%, what is the
total cost of a new backpack for $36?

Answers

Answer:

[tex]Total\ Cost = \$38.97[/tex]

Step-by-step explanation:

Given

[tex]Backpack = \$36[/tex]

[tex]Sales\ Tax = 8.25\%[/tex]

Required

Determine the Total Cost

Total cost is calculated as thus

[tex]Total\ Cost = Backpack + Backpack * Sales\ Tax[/tex]

[tex]Total\ Cost = \$36 + \$36 * 8.25\%[/tex]

[tex]Total\ Cost = \$36 + \$2.97[/tex]

In the diagram m<8=11y+7 and m<3=y+17.What is m<2

Answers

Answer:

C. 150

Step-by-step explanation:

Given:

m<8 = 11y + 7

m<3 = y + 17

Required:

Find m<2

Solution:

m<8 + m<3 = 180 (supplementary angles and linear pair theorem)

11y + 7 + y + 17 = 180 (substitution)

Collect like terms

12y + 24 = 180

Subtract 24 from each side

12y = 180 - 24

12y = 156

Divide both sides by 12

y = 156/12

y = 13

m<2 = m<8 (alternate exterior angles are congruent)

m<2 = 11y + 7

Substitute y = 13 into the equation

m<2 = 11(13) + 7 = 143 + 7

m<2 = 150°

Because of the vertical angles and alternate interior angles we know these are similar triangles. Use what you know about proportional sides to solve for the unknown side ,x

Miniver loved the days of old When swords were bright and steeds were prancing; The vision of a warrior bold Would set him dancing. Miniver sighed for what was not, And dreamed, and rested from his labors; He dreamed of Thebes and Camelot, And Priam's neighbors. Minever mourned the ripe renown That made so many a name so fragrant; He mourned Romance, now on the town, And Art, a vagrant. Minever loved the Medici, Albeit he had never seen one; He would have sinned incessantly Could he have been one. Miniver cursed the commonplace And eyed a khaki suit with loathing; He missed the medival grace Of iron clothing. Miniver scorned the gold he sought, But sore annoyed was he without it; Miniver thought, and thought, and thought, And thought about it. Miniver Cheevy, born too late, Scratched his head and kept on thinking; Miniver coughed, and called it fate, And kept on drinking. Which answer reflects a similar theme in another format?
