Hey there!

Set up an equation. This would be 4+0.5x=12. You have to get x by itself, so subtract 4 on each side. You get 0.5x=8. Divide by 0.5 on each side to get x=16. Heidi purchased 16 tickets.

I hope this helps!

Vance wants to determine if an old photo frame is still rectangular. The height of the frame is
sveticcg [70]

Answer:

<em>The old photo frame is still rectangular</em>

Step-by-step explanation:

<u>Rectangles</u>

The rectangle shape can be identified because it has 4 internal angles of 90° each. The diagonal forms with two adjacent sides a right triangle where the Pythagora's Theorem must stand. Being a and b the length of the sides of the rectangle and d the diagonal, then:

d^2=a^2+b^2

Vince's photo frame has dimensions of 8 inches and 6 inches, with a diagonal of 10 inches. If the above condition is met, then the frame is still rectangular.

Calculating:

10^2=6^2+8^2

100=36+64

100=100

Since the condition is met, the old photo frame is still rectangular

The sun casts a shadow from a flag pole. The height of the flag pole is three time the lenght of its shadow. The distance betwee
Alex73 [517]

Answer:

The height of the flag pole will be = 18.96 ft.

Step-by-step explanation:

See the attached diagram.

AB is the flag pole and the length of the shadow is AC.

Now, Δ ABC is a right triangle and has AB = 3x ft., BC = 20 ft. and AC = x ft.

So, applying Pythagoras theorem ,

AB² + AC² = BC²

⇒ (3x)² + x² = 20²

⇒ 10x² = 400

⇒ x² = 40

⇒ x = 6.32 ft. (Approx.)

So, the height of the flag pole will be = 3x = 3 × 6.32 = 18.96 ft. (Answer)
