The radius of a circle is 1 yard. What is the circle's circumference?
r=1 yd
Use 3.14 for .
The circumference of the circle is 6.28 yards.
What is circumference of the circle?"It is the length of the boundary of the circle."
Formula to calculate the circumference of the circle:C = 2 × π × r, where 'r' is the radius of the circle.
For given example,
r = 1 yd.
π = 3.14
Using the formula for the circumference of circle,
⇒ C = 2 × π × r
⇒ C = 2 × 3.14 × 1
⇒ C = 6.28 yd.
Therefore, the circumference of the circle is 6.28 yards.

Type the solution
Answer:x = 7
Step-by-step explanation:
Simply because:
5(1 + x) = 40
(1 * 5 + x * 5) = 40
(5 + 5x) = 40 5 + 5x = 40
5 + -5 + 5x = 40 + -5
0 + 5x = 40 + -5
5x = 40 + -5

I took a pic, I hope that's fine
Answer:
Well in order to find the y-intercept, the “x” has to be 0. To find that we need to find the pattern and to ind the pattern you would need to find the slope. The slope is -4 or 4/ -1
So the Y is 4 and the X is -1
So use that to add or subtract for the pattern
1, -4
0, 0
The y- Intercept is 0 or option (A)

Imagine that you need to create a scale drawing of this sign. The scale drawing will
be used to create a mold that will be used to manufacture the sign. Use the grid to
make a scale drawing of this sign. Include a key to show the relationship between
the dimensions in the scale drawing and the dimensions of the actual sign. Label all
sides in the scale drawing. Show your work. (3 points)
A scale drawing with a 1: 0,8 scale will have sides that measure 2.24, 1.6, and 3.2.
What is a scale drawing?A scale drawing refers to a drawing that has been made bigger or smaller but preserves the proportions of a drawing.
How to make the scale drawing of the sign?The first step is to decide the scale. In this case, the best scale is 1:0.8, which means the new drawing is 0.2 smaller. This scale is ideal because this sign is slightly bigger than regular signs.
Draw the sign by multiplying each side by the scale (0,8).
