A store Is having a sale where movies are 15% off their original price. a movien is on sale for $22.10 what was the orgial price
sergeinik [125]
X= original $

Original $ - % of original $= total $

x - 15%x= $22.10
x- 0.15= 22.10
Combine like terms
0.85x= 22.10
Divide both sides by 0.85
x= $26 original price

Hope this helps! :)

can you explain how to decompose a rectangle into congruent triangles? how does the area of the decomposed pieces relate to the
Annette [7]
You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

From a point on the ground that is 120 feet from the base of a vertical tree, the angle of elevation to the top of the tree is 3
andriy [413]

Answer:

\boxed {\boxed {\sf 69.28 \ feet}}

Step-by-step explanation:

Assuming that the tree is perpendicular with the ground, we can use trigonometric ratios to find the height of the tree.

First, let's draw a diagram. From the point on the ground to the base, it is 120 feet and forms a 30 degree angle. We want to find the height of the tree, which is labeled h. (The diagram is attached and not to scale).

Next, recall the ratios.

  • sin(θ)= opposite/hypotenuse
  • cos(θ)= adjacent/hypotenuse
  • tan(θ)= opposite/adjacent

We see that the height is opposite the 30 degree angle and 120 is adjacent.

  • opposite=h
  • adjacent=120

Since we are given opposite and adjacent, we must use tangent.

tan ({\theta)=\frac{opposite}{adjacent}

Substitute the values in.

tan(30)=\frac{h}{120}

We are solving for h, so we must isolate it. It is being divided by 120 and the inverse of division is multiplication. Multiply both sides by 120.

120*tan(30)=\frac{h}{120}*120

120*tan(30)=h

120*0.5773502692=h

69.2820323=h

Round to the hundredth place (2 decimal places). The 2 in the thousandth place tells us to leave the 8 in the hundredth place.

69.28 \approx h

The height of the tree is about <u>69.28 feet.</u>
