Madhu is hanging a string of flowers on the perimeter of a rectangular pool deck. The deck is 30 feet long and 24 feet wide. How

Igoryamba

Answer:

108 feet long

Step-by-step explanation:

You know that to find the perimeter you have to add up all the sides. A rectangle has 4 sides, so 30+30 is 60 and 24+24 is 48. Add 60 and 48 up and you get 108 as the perimeter. Since Madhu is hanging a string of flowers on the PERIMETER, the flower string will need to be 108 feet long.

Hope this Helped!

Use a compass and straightedge to construct an equilateral triangle using the length (AB) ̅ for the sides.

Nostrana [21]

For a better understanding of the solution provided here please go through the diagram in the file attached.

Let us begin the construction of the triangle in a step by step fashion.

Step 1 Take AB as the base.

Step 2 Take the point of the compass and place it on A and take the width of the compass to be AB.

Step 3 Make an arc (as shown in green for convenience).

Step 4 Now, take the point of the compass and place it on B keeping the width of the compass to be AB.

Step 5 Make an arc (as shown in yellow for convenience) such that it intersects the arc made in Step 3 at the point C.

Step 6 Join the points A and C, and B and C.

The made triangle is the required equilateral triangle, $\Delta ABC$ . All the sides will be equal to the length AB.

Y varies directly as the square of x. If y is 25 when x is 3 find y when x is 2

Vilka [71]

Answer:

y = $\frac{100}{9}$

Step-by-step explanation:

given y varies as the square of x then the equation relating them is

y = kx² ← k is the constant of variation

to find k use the given condition y = 25 when x = 3

k = $\frac{y}{x^{2} }$ = $\frac{25}{9}$

⇒ y = $\frac{25}{9}$ x²

when x = 2

y = $\frac{25}{9}$ × 4 = $\frac{100}{9}$
