Hw 28 shades figure
ra1l [238]

Answer:

Prat 9) SF=2, x=16\ in

Part 10) SF=0.5, x=14\ ft

Part 11) SF=0.5, x=3.5\ ft

Part 12) SF=3, x=7\ m

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

SF-----> the scale factor

a----> area of the shaded figure

b----> area of the unshaded figure

SF^{2} =\frac{x}{y}

Problem 9) we have

a=216\ in^{2}

b=54\ in^{2}

substitute in the formula

SF^{2}=\frac{216}{54}

SF^{2}=4

SF=2 ------> the scale factor

To find the value of x, multiply the length of the unshaded figure by the scale factor

x=(2)(8)=16\ in

Problem 10) we have

a=161\ ft^{2}

b=644\ ft^{2}

substitute in the formula

SF^{2}=\frac{161}{644}

SF^{2}=0.25

SF=0.5 ------> the scale factor

To find the value of x, multiply the length of the unshaded figure by the scale factor

x=(0.5)(28)=14\ ft

Problem 11) we have

a=10.5\ ft^{2}

b=42\ ft^{2}

substitute in the formula

SF^{2}=\frac{10.5}{42}

SF^{2}=0.25

SF=0.5 ------> the scale factor

To find the value of x, multiply the length of the unshaded figure by the scale factor

x=(0.5)(7)=3.5\ ft

Problem 12) we have

a=4,590\ m^{2}

b=510\ m^{2}

substitute in the formula

SF^{2}=\frac{4,590}{510}

SF^{2}=9

SF=3 ------> the scale factor

To find the value of x, divide the length of the shaded figure by the scale factor

x=(21)/(3)=7\ m
