Answer:

The total cost of  to re-decorate the community hall is £2172.

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 wide and 3m high.

The paint will be required for 4 walls and ceiling.

Let us find area of walls and ceiling.

Are of Walls and Ceiling = 2(l+b)h+lb=2(40+15)3+(40\times15)= 6\times55+600= 330+600 =930m^2

Therefore, the area of walls and ceiling is 930 square meters.

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

Total Painting cost = 10 \times \frac{930}{25} = \£372

Therefore, the total painting cost of wall is £372.  

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

Area of floor = l \times b = 40\times15 =600m^2

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

Total Cost for tiles = 3\times600= \£1800

Therefore, the total cost for tiles is £1800.

Now let us find total cost of  to re-decorate the community hall;

Total Cost =  the total painting cost of wall + the total cost for tiles = \£1800+\£372= \£2172

Hence, the total cost of  to re-decorate the community hall £2172.

   ln 5
e              =    ?
                                    x
Keep in mind that y=e     and y = ln x are inverse functions of one another.
  ln 5
e       ,  we can drop both the "e" and the "ln 5."  We are left with 5 (answer).
                                                                                        ln 5
Alternatively, we could take the ln of both sides of y = e

which will result in ln y = (ln 5) ln e.  Note that ln e = 1 (these two functions are inverses of one another).

Then we are left with ln y = ln 5.  Dropping the "ln" operator from both sides,

y=5 (same as before).

Graph the line with slope −1/2 and y-intercept −5.
Allushta [10]

First, we can write the equation of the line using the information provided:

\begin{gathered} y=mx+b \\ where: \\ m=slope=-\frac{1}{2} \\ b=y-intercept=-5 \\ so: \\ y=-\frac{1}{2}x-5 \end{gathered}

Now, we can create a table:

Finally, we can graph the line:

Predict if the product will be greater than, less than or equal to the second factor 4/5 x 1 2/5 = y
Radda [10]

Answer:

The product will be less than the second factor.

Step-by-step explanation:

Given the expression

\frac{4}{5}\:\times \:1\frac{2}{5}\:=y

solving to determine the product value

y=\:\frac{4}{5}\times \:\:1\frac{2}{5}

  =\frac{4}{5}\times \frac{7}{5}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

  =\frac{4\times \:7}{5\times \:5}

  =\frac{28}{5\times \:5}

  =\frac{28}{25}

As the value of the second factor is:

1\frac{2}{5}=\frac{7}{5}=1.4

And the product value is:

y=\frac{28}{25}=1.12

It is clear that the product value 'y = 1.12' is lesser than the second factor value '1.4'.

i.e. 1.12 < 1.4

Thus, the product will be less than the second factor.

Which of the following would you most likely measure in kilograms?
garri49 [273]

Answer:

The mass of a longhorn cow.

Step-by-step explanation:

Kilograms will measure mass, not length, so we are left between two options. Kilograms would be used for heavier objects, so between a paper clip (which would be likely measured in grams,) and the longhorn, the cow would be what you would measure in kilograms.
