Answers

Answer:

4. Option A is correct.

7. Option C is correct.

8. Option A is correct.

11. Option B is correct.

12. Option C is correct

Step-by-step explanation:

4.

The sides of equilateral triangle are same.

It is given that lengths of the sides are 9, 9, and 9.

Since the side lengths are same, therefore the given triangle is an equilateral triangle.

Option A is correct.

7.

It is given that the line a is parallel to line b and the measure of angle 7 is 135 degree.

\angle 6+\angle 7=180^(\circ)              (Supplementary angles)

\angle 6+135^(\circ)=180^(\circ)

\angle 6=45^(\circ)

\angle 4=\angle 6                     (Alternative interior angles)

\angle 4=45^(\circ)

Option C is correct.

8.

x-3=65              (Corresponding angles)

x=68

46+65+y-3=180                                    (Supplementary angles)

y=72

Option A is correct.

11.

If a transversal line intersect two lines are parallel lines, then their corresponding angles are same.

It is given that

\angle 1=\angle 2

Since angle 1 and 2 are corresponding angles, therefore we can say that the lines a and b are parallel.

Option B is correct.

12.

x-1=63              (Corresponding angles)

x=64

Option C is correct.
The answer to #4 is A equilateral because all the sides are the same. the sides are equal. 
# 7 would be c, 45 you have to make sure the sum is 180 #8 is B the same goes for that on fill in x and y. #11 isD And # 12 is c the sum must be 180.

A circle has a radius of 12 cm. If the radius of the circle is increased by a factor of 7, how many times larger will the circle's circumference be?

Answers

Considering it's own equation, the circumference of the circle will be increased by a factor of 7.

What is the circumference of a circle?


The circumference of a circle of radius r is:

C = 2\pi r

Since the radius is elevated to power 1, if it is multiplied by a factor of 7, the circumference of the circle will also be increased by a factor of 7.

snooker is a kind of pool or billiards played on a 6 foot by 12 foot table. the side pockets are half way down the rails . find the distance to the nearest tenth of a foot, diagonally across the table from the corner pocket to corner pocket

Answers

Let length be 12 ft (l = 12 ft) and width be 6 ft (w = 6ft).

The side pocket will be on the half of its length (l). To calculate the distance, we will use the distance d as a hypotenuse of the right triangle with sides w and l/2.

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of two other sides:

d² = w² + (l/2)²

We have:

d = ?

w = 6 ft

l = 12 ft

d² = 6² + (12/2)²

d² = 6² + 6²

d²= 2 * 6²

d² = 2 * 36

d² = 72

d = √72

d = 8.48 ft

Since 1 ft is 12 in, then 8.48 ft is 101.76 in:

8.48 * 12 in = 101.76 in

Hope this helps!
