ASAP PLEASE ANSWER quadrilateral ABCD is dilated at center (0,0) with scale factor 1/2 to form quadrilateral A'B'C'D'. wha is th
zhenek [66]

Answer:

|A'B'|=\sqrt{5}

Step-by-step explanation:

The points A and B have coordinates at (0,4) and (4,2) respectively.

The distance formula can be used to find the length of AB.

|AB|=\sqrt{(4-0)^2+(2-4)^2}

|AB|=\sqrt{(4)^2+(-2)^2}

|AB|=\sqrt{16+4}

|AB|=\sqrt{20}

|AB|=2\sqrt{5}

Since quadrilateral ABCD was enlarged with  a scale factor of \frac{1}{2}.

The length of A'B' is

\frac{1}{2}|AB|

=\frac{1}{2}\times2\sqrt{5}

\therefore |A'B'|=\sqrt{5}

A community hall is in the shape of a cuboid the hall is 40m long 15m high and 3m wide. 10 litre paint covers 25m squared costs
krek1111 [17]

Answer:

Total cost for tiles and paints is $924.  

Step-by-step explanation:

We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.

The paint will be required for 4 walls and ceiling.

Let us find area of walls and ceiling.

\text{Area of walls and ceiling}=(2*40*15)+(2*3*15)+(40*3)

\text{Area of walls and ceiling}=1200+90+120

\text{Area of walls and ceiling}=1410

Therefore, the area of walls and ceiling is 1410 square meters.

Given: Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. Therefore,  

\text{ The total painting cost}=10*(\frac{1410}{25})

\text{ The total painting cost}=10*56.4=564

Therefore, the total painting cost is $564.  

Tiles will be required for floor. Let us find the area of floor.

\text{Area of floor} = 40*3\text{ square meters}

\text{Area of floor} =120\text{ square meters}

Given: 1m squared floor tiles costs $3. So,

\text{Total cost for tiles} = 3*120 = 360

Therefore, the total cost for tiles is $360.  

Now let us find combined total cost of tiles and paint.

\text{Combined total cost}= 564+360 = 924

Therefore, the combined total cost of tiles and paint is $924.

Lemur [1.5K]

Answer:


Step-by-step explanation:

75 % of 10 liters

(75/100)*10= 3/4*10=30/4 liters

Removing the 75% of 10 liters

10 -30/4= 10/4=2.5 liters
