Kat is painting the edge of a triangular stage prop with reflective orange paint. The lengths of the edges of the triangle are (
vfiekz [6]
We are given with three lengths of a triangle expressed in terms and variables: (3x – 4) feet, (x^2 – 1) feet,  and (2x^2 – 15) feet. The perimeter of the triangle is equal to the sum of the three sides of the triangle. In this case, the sum is 3x^2 + 3x -20. When x is equal to 4, we substitute  <span>3*16 + 3*4 -20 equal to 40 feet.</span>

Tasya [4]

Answer:

  p = 55 + 35h

Step-by-step explanation:

Let p and h represent the price of the service call and the hours worked, respectively. The price charged is 35 dollars for each hour, so the time-based part of the price is 35h. The base fee of 55 dollars is added to that for a total price of ...

  p = 55 + 35h

What percent of 33 is 96
Nataly_w [17]
<span>96/x=100/33
(96/x)*x=(100/33)*x       - we multiply both sides of the equation by x
96=3.0303030303*x       - we divide both sides of the equation by (3.0303030303) to get x
96/3.0303030303=x 
31.68=x 
x=31.68

now we have: 
33% of 96=31.68

Find the volume of a right circular cone that has a height of 18.9 in and a base with a
Dmitriy789 [7]

Answer:

The volume of the cone is:

  • <u>112.6 cubic inches.</u>

Step-by-step explanation:

You should know that the volume of a straight circular cone is equal to:

  • Cone volume = (1/3) PI * r ^ 2 * h

Where:

<em>r = radius. </em>

<em>h = height. </em>

Since the radius and diameter are not provided in the exercise but the circumference, the circumference formula should be used and the diameter must be cleared:

  • Circumference = PI * Diameter.

When clearing you get:

  • Diameter = circumference / PI

By replacing the data you get:

  • Diameter = 15 inches / PI
  • Diameter = 4.77 inches.

Since the radius is equal to half the diameter, then the diameter is equal to 2,385 inches, now having the value of radius we proceed to replace in the volume formula:

  • Cone volume = (1/3) PI * 2.385 in^2 * 18.9 in
  • Cone volume = 112.581541 in^3
  • <u>Cone volume = 112.6 in^3</u>
