From the side, area is that of a rectangle added to a trapezoid or triangle, depending on how you slice it
.. rectangle + trapezoid = (4 ft)*(24 ft) +(4 ft +8 ft)*(16 ft)/2 = 192 ft^2
.. rectangle + triangle = (4 ft)*(40 ft) +(1/2)*(4 ft)*(16 ft) = 192 ft^2

The side area is multiplied by the width to find the volume.
.. V = (192 ft^2)*(20 ft) = 3840 ft^3 . . . . . . maximum water volume

What did this person do wrong? Honestly really stuck and do not remember geometry!
dmitriy555 [2]

Answer:

See below.

Step-by-step explanation:

Using the right triangle altitude theorem, the correct proportions are:

\dfrac{AB}{AC} = \dfrac{AC}{AD}

\dfrac{AB}{x} = \dfrac{x}{AD}

\dfrac{25}{x} = \dfrac{x}{16}

x^2 = 25 \times 16

x = 20

AC = 20 cm

\dfrac{AB}{CB} = \dfrac{CB}{DB}

\dfrac{AB}{y} = \dfrac{y}{DB}

\dfrac{25}{y} = \dfrac{y}{9}

y^2 = 25 \times 9

y = 15

CB = 15 cm

Help plsssssssssssssssss​
KATRIN_1 [288]

Answer:

1) 75 copies were sold

2)expected wage=720

Step-by-step explanation:

in this equation, y represents wages and x represents number of copies sold

lets take the trendline, y=6x+120

since the amount earnt is $570, we can take this to be our y variable

570=6x+120

450=6x

x=75

1) 75 copies r sold

2) this time we substitue the 100 for x

y=6(100)+120

y=600+120

y=720

2) expected wage=720
