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 slope of the line parallel to the line 9y + 2x = 54?<br> Select one:
Paraphin [41]

Answer:

The slope is -2/9

Step-by-step explanation:

9y + 2x = 54

Solve for y to get the equation in the form

y = mx+b where m is the slope and b is the y intercept

Subtract 2x from each side

9y + 2x -2x = -2x+54

9y = -2x+54

Divide by 9

9y/9 = -2x/9 + 54/9

y = -2/9 x +6

The slope is -2/9

Parallel lines have the same slope
