Answer:

Linear speed= V= 175.84 m/s

Step-by-step explanation:

A wheel with a radius of 7 inches is rotating at 4 revolutions per second.

Linear speed v = rw

r= radius

r= 7 inches

w= angular speed

W= 4rev/s

But one rev= 2π

W= 4*(2π)/s

W= 8π/s

V= rw

V=7*8*3.14

V= 175.84 m/s

1. The backdrop of the altar in a church is triangular in shape. It has a base of 10.5 meters
FrozenT [24]

Answer:

#1

<u>Area of triangle backdrop:</u>

  • A = 1/2bh = 1/2(10.5)(8.5) = 44.63 m²

<u>Area of the cloth:</u>

  • A = 4.5*4 = 18 m²

<u>Uncovered area:</u>

  • 44.63  - 18 = 26.63 m²

Choice A

#2

<u>Area of the cut piece:</u>

  • A = πr² = 3.14*7.6² = 181.37 cm²

<u>Area of the square piece:</u>

  • A= a² = 34² = 1156 cm²

<u>Remaining piece is:</u>

  • 1156 - 181.37 = 974.63 cm²

Choice B

Question 3
marin [14]

To find differences in the angles of the intersections we must know how many degrees each angle corresponds to. We must also take into account that the sum of the internal angles must equal 180°.

<h3>What is a triangle?</h3>

A triangle is a polygon that is characterized by having three sides, three vertices, and three angles. An indispensable rule of the interior angles of the triangles is that they must add up to 180º.

Triangles are classified according to their characteristics as shown below:

  • Equilateral triangle: It is a type of triangle that is characterized by having all equal sides. Consequently, all the angles of an equilateral triangle are 60º. The equilateral triangle is a regular polygon.
  • Isosceles triangle: It is a type of triangle that is characterized by having two equal sides and one different. Consequently, it also has two equal angles.
  • Scalene triangle: A scalene triangle is one that is characterized by having all its sides and angles unequal, that is, different from each other.

According to the above, depending on the measurements of the length of the sides and the angles of a triangle, its characteristics and classification change.

Note: This question is incomplete because the image is missing. However I can answer it based on my general prior knowledge.
