Answer: C. 5.4 Blocks

Step-by-step explanation:

<u>Given information</u>

5 bags = 3 blocks

<u>Set variable</u>

Let x be the number of blocks

<u>Constructure proportional equation</u>

\frac{3}{5} } ~=~\frac{x}{9}

<u>Cross multiply the fraction</u>

(3)~*~(9)~=~(5)~*~(x)

27~=~5x

<u>Divide 5 on both sides</u>

27~/~5~=~5x~/~5

\Large\boxed{x=5.4~blocks}

Hope this helps!! :)

A smaller square is located inside a larger square. the length of the smaller square is 7 cm, and the length of the square is 12
patriot [66]
Let S=larger square side and s=smaller square side.  The area between the larger and smaller is simple the larger area minus the smaller area.  The area of any square being s^2.  So our remaining area is:

A=S^2-s^2

A=144-49=95 cm^2

Solve for the 3 sides
mel-nik [20]

Answer:

1. x = 2√3 or 3.46

2. y = 4√3 or 6.93

3. z = 4√6 or 9.80

Step-by-step explanation:

1. Determination of the value of x.

Angle (θ) = 60°

Opposite = 6

Adjacent = x

Tan θ = Opposite /Adjacent

Tan 60 = 6 / x

√3 = 6/x

Cross multiply

x√3 = 6

Divide both side by √3

x = 6 / √3

Rationalise

x = (6 / √3) × (√3/√3)

x = 6√3 / 3

x = 2√3 or 3.46

2. Determination of the value of y.

Angle (θ) = 60°

Opposite = 6

Hypothenus = y

Sine θ = Opposite /Hypothenus

Sine 60 = 6/y

√3/2 = 6/y

Cross multiply

y√3 = 2 × 6

y√3 = 12

Divide both side by √3

y = 12/√3

Rationalise

y = (12 / √3) × (√3/√3)

y = 12√3 / 3

y = 4√3 or 6.93

3. Determination of the value of z.

Angle (θ) = 45°

Opposite = y = 4√3

Hypothenus = z

Sine θ = Opposite /Hypothenus

Sine 45 = 4√3 / z

1/√2 = 4√3 / z

Cross multiply

z = √2 × 4√3

z = 4√6 or 9.80
