the plane of a room is shown in the picture. the scale is 2 inches: 6 feet. what is the actual length of the room?
what is the actual width of the room? what is the actual area of the room?

Answer:

x = 7, y = 16

Step-by-step explanation:

From the diagram shown;

2x+5 = x+12

collect the like terms

2x-x = 12 - 5

x = 7

Similarly, y - 4 = x+5

y-4 = 7+5

y - 4 = 12

y - 12+4

y = 16

hence x = 7, y = 16

Answer:

Answer:

SSS or SAS

Step-by-step explanation:

Remark

Since the two diagonals bisect each other, you have created two sets of equal lines. If that is the case, then you could prove the equality of the triangles 2 different ways.

1) The angles at the center are vertically angles which makes them equal. Since they are equal, the triangles are congruent by SAS. Notice that the angle is between the 2 equal sides.

2) Since CD and AB are marked as being equal, the triangles are congurent by SSS.

Answer:

y = 27

Step-by-step explanation:

The output is the value of y when x = 5

Substitute x = 5 into the function , that is

y = 12 + 3(5) = 12 + 15 = 27 ← output

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Step-by-step explanation:

Given

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Required

Determine an expression for the area

Area is calculated as:

[tex]Area = Length *Width[/tex]

[tex]Area = (4w^2 + 3w - 1) * (5w - 2)[/tex]

Expand

[tex]Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2[/tex]

Collect like terms

[tex]Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2[/tex]

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Answer:

6.13

Step-by-step explanation:

This diagram shown is a right triangle;

USing the SOH CAH TOA idenity

Adjacent = x

Hypotenuse = 8

Angle of elevation = 40 degrees

cos theta = adj/hyp

cos 40 = x/8

x = 8cos40

x = 6.13

Hence the value of x to the nearest hundredth is 6.13

Answer:

Step-by-step explanation:

3(x-y)-3x-7y=3(5)-(-5)

3x-3y-3x-7y=15+5

-10y=20

y=-2, since x-y=5

x-(-2)=5

x+2=5

x=3

So the solution is the point (3,-2)

Answer: Area= length x width

63

Answer:

Step-by-step explanation:

Area of the Wall minus the Area of the headboard      

Area = length x width      in  this use tall as length and wide as width

Area Wall - Area Headboard  =  (Tall wall)(Wide wall)  -  (Tall head)(Wide head)

                 =  (9)(7) - (5)(6) feet

                 =    63 - 30  feet

                 =   ????                      I'll let you finish it

The area of the space that will remain after she places the bed against the wall is 30 feet².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

We have,

The headboard, which is 6 feet wide and 5 feet tall.

The headboard on a wall that is 7 feet wide and 9 feet tall.

So, Area of remaining space

= Area of the Wall - Area of the headboard      

= (9)(7) - (5)(6) feet

= 63 - 30  

= 30 feet²
