To find the length of the frame, we're effectively calculating the circle's circumference, which measures the distance around the circle's edge. The formula used is C=2πr, where r denotes the radius.

D = 20 in
r = D/2 = 20 in/2 = 10 in
C = 2π(10 in) = 20π in ≈ 62.83 in

Thus, the metal frame is approximately 62.83 inches long.

2.6 Puzzle time how can you make sure to start a fire with two sticks?
Svet_ta [4341]

Answer:

"Ensure that one of them is a match"

Step-by-step explanation:

Generating heat through friction requires some practice. By elevating the wood's temperature, it's feasible to reach the necessary ignition temperature.

Successful fire-starting depends on proper technique and equipment. Failures often arise from inadequate approach and gear, which can complicate the learning process.

When selecting wood, aim for the following criteria:

  • Dry tinder
  • Wood should be compressible; if it isn't, it's too challenging.
  • Wood that is moderately strong but not overly tough
  • Avoid sap in the wood

Position the two pieces of wood at a 90-degree angle, resembling a cross. Support one stick vertically on the ground, while the other rubs against it quickly, using intervals.

Underneath, place dry tinder that catches fire swiftly after it's ignited.

For the Puzzle, remember the order of the words:

Ensure that one of them is a match.

Utilize tree wood, apply friction and heat until ignition occurs.

The length if Marshall's rectangular poster is 2 times its width.If the perimeter is 24 inches, what is the area of the poster.
Inessa [3926]
Dimensions of the rectangle are defined as Length=2x
Width=x
The formula for perimeter is given by 2(Length) + 2(Width).

First, we need to determine the dimensions of the rectangle, specifically its length and width.

We can derive this equation:
24=2(2x)+2(x)
4x+2x=24
6x=24
x=24/6
x=4

Consequently, Length becomes 2x, leading to 2(4)=8.

Therefore, the length is 8 inches and the width is 4 inches.

Next, we will calculate the area of the rectangle.
The area can be computed as Length multiplied by Width.

Area=(8 in)(4 in)=32 in²

Conclusion: The area of Marshall's rectangular poster is 32 in².

Two parallel lines are crossed by a transversal. What is the value of x ?
tester [3938]

Answer:

Angle x = angle 115°.

Step-by-step explanation:

Given: We have two parallel lines intersected by a transversal.

To find: The value of x.

Solution: Since two parallel lines are intersected by a transversal, corresponding angles, which are a pair lying on the same side of the transversal—one being on the interior and the other on the exterior—are equal.

Thus, angle x = angle 115, being corresponding angles.

Therefore, angle x = angle 115.
