Vince made a scale drawing of the middle school. He used the scale 5 inches : 8 feet. If the gym is 45 inches wide in the drawin
mrs_skeptik [129]

Scale drawings are used to show an actual image using lesser dimensions.

The width of the actual gym is 72 feet

The scale is given as:

Scale = 5\ inches : 8\ feet

Represent the width of the actual gym with w, so, we have the following equivalent ratio

45\ inches : w = 5\ inches : 8\ feet

Cancel out the common units

45: w = 5: 8\ feet

Express as fraction

\frac{45}{w} = \frac{5}{8\ feet}

Cross multiply

5w = 45 \times 8\ feet

Divide both sides by 5

w = 9\times 8\ feet

w = 72\ feet

Hence, the width of the actual gym is 72 feet

A sheet of metal that is 30cm wide and 600cm long is to used to make a rectangular eavestrough by bending the shett an equal amo
tensa zangetsu [6.8K]

Answer:

The sheet should be turned up 7.5cm on each side to obtain maximum volume.

Step-by-step explanation:

If we make a rectangular eavesdrop, by bending the sheet along dotted line, then.

Height of eaves trough = x cm

Length of eaves trough = 600 cm

Width of eaves trough =  (30 - 2x) cm

We know that Volume is given by:

V = Length · Width · Height

V = (x)(30 - 2x)(600)

V = -1200x² + 18000x

To maximize the volume, we take the derivative and put it equal to zero.

\frac{dV}{dx} =\frac{d}{dx}( -1200x^2 +18000x)=0\\\frac{d}{dx}( -1200x^2 +18000x) = 0\\-(2)1200x+18000=0\\-2400x+18000=0\\x=\frac{18000}{2400}\\ x=7.5cm
