A room 9m long,6m broad and 3.6 m high has one door 1.4m by 2m and two windows,each 1.6m by 75cm find: the cost of white-washing
Tcecarenko [31]

Answer:

The cost of white-washing the walls from inside at the rate of 22.50 per m² is 1098

Step-by-step explanation:

Step 1: Finding the area of the room

Area of the room  = Length X breadth

Length  = 9m long

Breadth =  6m broad

Area of the room  = 9 x 6 =54 square metres

Step 2: Finding the area of the door

Area of the door = Length x breadth

Breadth =  1.4m

Length = 2m

Area of the door = 1.4 x 2  = 2.8 square metres

Step 3: Finding the area of the Window

Area of the window= Length x breadth

Length = 1.6 m

Breadth = 75 cm

Converting cm to m

we have

75 cm  =0.75 m

Area of the 1 window=  1.6 x 0.75 = 1.2 square metres

Step 4: Finding the area to be painted

Area to be painted = Total area of the room - area of the door - 2(area of the window)

Area to be painted = 54 - 2.8 - 2(1.2)

Area to be painted = 54 - 2.8 - 2.4

Area to be painted  = 48.8 square metres

Step 5: Finding the cost for painting

For painting one square metre = $22.50

For painting 48.8 square metres = 22.50 x 48.8 = 1098

I need help with coming up with equation
Natali5045456 [20]

Let's call a child's ticket c and an adult's ticket a. From this, we can say:

c + a = 116,

since 116 tickets are sold in total.


Now, we are going to need to find another equation (the problem asks us to solve a systems of equations). This time, we are not going to base the equation on ticket quantity, but rather ticket price. We know that an adult's ticket is $17,000, and a child's ticket is thus

\$17000 \cdot (1 - \dfrac{1}{4}) = \$12750.


Given these values, we can say:

17000a + 12750c = 1653250,

since each adult ticket a costs 17,000 and each child's ticket c costs 12,750, and these costs sum to 1,653,250.


Now, we have two equations:

17000a + 12750c = 1653250

c + a = 116


Let's solve:

17000a + 12750c = 1653250

a = 116 - c

  • Find a on its own, which will allow us to substitute it into the first equation

17000(116 - c) + 12750a = 1653250

  • Substitute in 116 - c for a

1972000 - 17000c + 12750c = 1653250

  • Apply the Distributive Property

1972000 - 4250c = 1653250

  • Combine like terms

4250c = 318750

  • Subtract 1972000 from both sides of the equation and multiply both sides by -1

c = 75


We have now found that 75 child's tickets were sold. Thus,

75 + a = 116 \Rightarrow a = 116 - 75 = 41,

41 adult tickets were sold as well.


In sum, 41 adult tickets were sold along with 75 child tickets.

Dropping less than two inches per mile after emerging from the mountains, a river drains into the ocean. One Day's discharge at
pashok25 [27]
So, one trillion is 1 and twelve zeros, thus 2.4 trillion is 2 trillions and 400 billions or 24 followed by eleven zeros, because the "4" is using up a space.

now, 1 million is 1 and six zeros, thus 100 millions is 100 and six zeros or 1 and 8 zeros.

now, is 2.4 trillions in four months, thus 2.4trillion/4 will give us how many gallons in 1 month.

to find how many households, simply let's divide it by 100 millions

\bf \cfrac{\stackrel{\textit{2.4 trillions}}{24\times 10^{11}}}{4}\implies \cfrac{24}{4}\times 10^{11}\implies 6\times 10^{11}
\\\\\\
\cfrac{\stackrel{\textit{gallons per month}}{6\times 10^{11}}}{\stackrel{households}{1\times 10^8}}\implies \cfrac{6}{1}\times \cfrac{10^{11}}{10^8}\implies 6\times 10^{11}\times 10^{-8}
\\\\\\
6\times 10^{11-8}\implies 6\times 10^3\implies \stackrel{\textit{gallons per household}}{6000}

Divide. −425÷(−5) −2225 −825 825 2225
Alex17521 [72]

Answer: The correct answer would be -85.


Step-by-step explanation: This is because the -5 becomes positive because it is inside parentheses.

This would make the expression: -425 ÷ 5.

-425 ÷ 5 is equal to -85.

Hope this helps and have a nice day! :)
