Madeline uses this scale model of a design she plans to paint on a wall. She uses the key 1 cm = 1. 5 ft. One gallon of paint wi
Arte-miy333 [17]

The amount of paint required by Madeline will be 0.8325 gallons

<h3>What amount of paint will be required by Madeline?</h3>

Given that

1cm=1.5ft

We will first find the area of the wall

Area of the wall = Area of trapezoidal shape+ Area of triangular shape

Area of trapezoid = \dfrac{a+b}{2} \times h

a= 4cm

b=14cm

h=10cm

putting this values

A=\dfrac{4+14}{2} \times 10

A=90cm^{2}

Area of triangular shape=  \dfrac{1}{2} \times width\times height

width=14cm

height=8cm

putting the values

A=\dfrac{1}{2} \times 14\times 8=58cm^{2}

Total area of the wall= 90+58=148cm^{2}

since we have

1cm=1.5ft

148cm^{2} = 148\times (1.5)^{2} =333 ft^{2}

Now

1gallon = 400ft^{2}

so for  333 ft^{2}  amount of paint in gallons required will be

1ft^{2} =\dfrac{1}{400} gallons

333ft^{2} =\dfrac{333}{400} gallons=0.8325gallons

Thus the amount of paint required by Madeline will be 0.8325 gallons

What is the mean of 72,73,86,59,75,58,50,55
Rashid [163]
<h3><u>MEAN</u></h3>

Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.

<em>In this equation, you have 8 numbers. That means you will be dividing by 8. </em>

The first thing you need to do is add all the numbers. Add:

72+73+86+59+75+58+50+55 = \bf 528

Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.

Divide:

528 \div 8 = \bf 66

The mean is 66

144=12x <br> 45 =4x-27 <br> 2x-2=14 <br> 12x=44-10x does any one kno these questions?
Free_Kalibri [48]

Hello russell6333!

\huge \boxed{\mathfrak{Question} \downarrow}

Solve for x.

  1. 144 = 12x
  2. 45 = 4x - 27
  3. 2x - 2 = 14
  4. 12x = 44 - 10x

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

1) \:  \:  \: 144 = 12x \\  \frac{144}{12}  = x \\ \boxed{ \boxed{  \bf12 = x}}

__________________

2) \:  \:  \: 45 = 4x - 27 \\ 45 + 27 = 4x \\ 72 = 4x \\  \frac{72}{4}  = x \\  \boxed{ \boxed { \bf18 = x }}

__________________

3) \:  \:  \: 2x - 2 = 14 \\ 2x = 14 - 2 \\ 2x = 12 \\ x =  \frac{12}{2}  \\ \boxed{  \boxed{ \bf \: x = 6}}

__________________

4) \:  \:  \: 12x = 44 - 10x \\ 12x + 10x = 44 \\ 22x = 44 \\ x =  \frac{44}{22}  \\  \boxed{\boxed{  \bf \: x = 2}}

__________________

<h3><u>NOTE </u><u>:</u><u>-</u></h3>
  • To solve questions of these sorts, bring all the terms to one side & simplify it leaving x alone in the other side of the equation (other side of the equal to sign). After simplification you'll get the value of x.
  • Remember that the signs & operations will change when you bring a term to the other side of the equation.
  • So, addition will become subtraction, subtraction will become addition, multiplication will become division & division will become multiplication.
