All circles are similar to each other.
a. True
b. False

Answers

Answer:

The correct option is a.

Step-by-step explanation:

The given statement is all circles are similar to each other.

A circle is the set of points in a plane that are equidistant from a given point which is known as circle.

Two figures are similar if their corresponding sides are proportional.

Circles are completely dependent on its radius. The radius of any two circles are proportional for any point on the circles.

The statement "All circles are similar to each other" is true.

Therefore the correct option is a.

The statement "All circles are similar to each other" is true.

We know that,

Circles are a type of geometric shape with unique properties that set them apart from other shapes.

The defining feature of a circle is its set of points that are equidistant from a fixed point, known as the center.

This means that circles have a constant diameter and radii, regardless of their size.

Additionally, a circle's circumference is always proportional to its diameter, which is represented by the mathematical constant π.

Due to these consistent properties, all circles are considered to be similar to each other.

This means that any two circles have the same shape, but may differ in size.

Hence,

The statement that all circles are similar to each other is a fundamental truth in geometry and mathematics.

What will be the linear equation for the shown table?

Answers

Answer:

y=2x+5

Step-by-step explanation:

To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)

So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2

Slope = 2, now find b

So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5

Put it all together y = 2x + 5

Solve for X

(X+b)/4=c

Answers

Answer:

x=4c-b

Step-by-step explanation:

(x+b)/4=c (multiply both sides by 4)

x+b=4c( subtract both sides by b)

x=4c-b

What is the area of the figure? A.
256 square inches

B.
288 square inches

C.
320 square inches

D.
384 square inches

Answers

The answer is a. What you need to do is find the area of the shape if it were a perfect rectangle - (20)(16)=320 in^2. Next you make an imaginary square in the corner (it's a square because it's 8in by 8 in) and find the area - 8^2 or (8)(8)=64. Finally you subtract the values - 320 - 64 = 256 in^2 voila.

The spoke of a wheel reaches from the center of the wheel to its rim. If the circumference of the rim of the wheel is 42 inches, how long is each spoke? Round your answer to the nearest hundredth. A. 6.69 inches
B. 6.25 inches
C. 7 inches
D. 13.38 inches

Answers

The circumference of the wheel can be expressed by:

circumference = 2 \pi r
Where r = the radius of the wheel.

Since the spoke reaches from the center of the wheel to its rim then r = length of the spoke

By rearranging the circumference equation we get:

r = (circumference)/(2 \pi )

If circumference = 42 inches then:

r = (42)/(2 \pi )

r = 6.68
Which is closest to B

Your book may have a typo in it as the answer to 4 decimal places is 6.6845 which rounds down to 6.68, not up to 6.69.
