The circumference of the circle is 24π cm.

The area of a circle is given by the formula:

                                A = πr²

where A is the area of the circle and r is the radius.

In this problem, we know that the area of the circle is 144π cm^2. Substituting this value into the formula, we get:

                               144π = πr²

Dividing both sides by π, we get:

                               r² = 144

Taking the square root of both sides, we get:

                               r = 12

Therefore, the radius of the circle is 12 cm.

The circumference of a circle is given by the formula:

                               C = 2πr

Substituting the value of r, we get:

                               C = 2π(12)

Simplifying, we get:

                               C = 24π

Therefore, the circumference of the circle is 24π cm.

Answer:

Therefore, the circumference of the circle is 24π cm.

Step-by-step explanation:

A circle's circumference is the distance around its outside.. It is similar to the perimeter of other shapes such as squares. Consider it to be the line that defines the shape.

The circle's circumference is 24 cm.

The area of a circle is:

                              A = πr²

where A denotes the circle's area and its radius.

In this problem, we know that the area of the circle is 144π [tex]cm^2.[/tex] Exchange this value into the formula, and we get.

       144π = πr²

Divide π by both sides, and we get:

        r² = 144

Take the square root on both sides, and we get:

          r = 12

The radius of the circle is 12cm.

The circumference of a circle is:

          C = 2πr

Exchange the value of r, we get:

           C = 2π(12)

Finally, we get:

             C = 24π

Therefore, the circumference of the circle is 24π cm.

The part of the whole was not converted to a decimal or fraction

Step-by-step explanation:

700 is not 35% of 20.

This can be concluded with the product not being calculated properly to calculate 35% of 20.

We first need to turn 35% (whole number) into a decimal of 0.35 to figure out the percentage.

so the actual calculation:
0.35x20

= 7

Correct the error:
ANS: 7 is 35% of 20.

Answer:

B; 7

Step-by-step explanation:

35% = 0.35 (decimal form)

Therefore: 0.35 x 20 = 7

Step-by-step explanation

If you've ready any of our fraction walkthroughs before, you'll know we always kick the show off with a quick recap for the kids. The number above the dividing line is the numerator, and the number below the line is the denominator. Simple stuff but sometimes we can all get a little forgetful!

To visualize the question we are trying to solve, let's put 2/7 and 6 side-by-side so it's easier to see:

2

7

÷   6

So here is the incredibly easy way to figure out what 2/7 divided by 6 is. All we need to do here is keep the numerator exactly the same (2) and multiple the denominator by the whole number:

Can it possibly be that simply to divide a fraction by a whole number? Yup. I hate to disappoint you but this might be the easiest problem you've had to solve all day long!

Answer:

The line x=b2a will serve as the parabola's axis of symmetry.

Detailed explanation:

Graph the parabola y=x2−7x+2 .

To get the values of a, b, and c, compare the equation with y=ax2+bx+c.

In this case, a=1, b=7, and c=2.

To write the axis of the symmetry equation, use the coefficient values.

The line x=b2a serves as the axis of symmetry for a quadratic equation of the form y=ax2+bx+c. Therefore, x=(7)2(1) or x=72 is the equation of the axis of symmetry of the given parabola.

To determine the vertex's y coordinate, change x=72 in the equation.

y=(72)2−7(72)+2 =494−492+2 =49 − 98 + 84  =−414

The vertex's coordinates are (72, 414) as a result.

Answers for pictures 1, 2, &3

Question 1: P = 35 degrees

It is given to us that angles N and P are complementary.

Complementary angles means the sum of the angles = 90 degrees.

Because angles N and M are supplementary, meaning they = 180 degrees, you can subtract angle M from 180.

180 - M = N

180 - 125 = 55

N = 55 degrees

Now that we know N = 55 degrees, we subtract that from 90 degrees to find P for N + P = 90 degrees, so if we subtract 55 from 90 we will get the value of angle P.

90 - N = P

90 - 55 = 35

P = 35 degrees!

Question 2: Option 4

We are trying to figure out which angles are congruent to one another.

We can rule out option one, for angles 1 & 4 are supplementary meaning their sum = 180 degrees.

The same applies for options 2 & 3, leaving us with the correct answer, option 4. We can make sure this is true because angles 3 & 5 are alternate interior angles, and alternate interior angles of parallel lines are congruent.

Question 3: x = 5

The three different angles add up to 180 because they are a straight angle.

First, we need to find out what 9 and 10 are equal to.

To do so, we can subtract 85 from 180.

180 - 85 = 9x + 10x

9x + 10x = 95

Now that we have an equation, we can simplify to find the value of x.

9x + 10 = 95

19x = 95

Divide by 19 on each side to isolate the variable x

x = 5

Answer:

Question 6 & 9 is not a right-angled triangle. However, Question 7 & 8  is right-angled triangle.

Step-by-step explanation:

A triangle can be determined to be a right-angled triangle if and only if one of the following conditions is satisfied:

Pythagorean Theorem: If in a triangle, the square of the length of the longest side (the hypotenuse) is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right-angled triangle. Symbolically, if a, b, and c are the lengths of the sides of the triangle, with c being the length of the hypotenuse, then a^2 + b^2 = c^2.

Angle criterion: If in a triangle, one of the angles is equal to 90 degrees, then the triangle is a right-angled triangle.

Right Angle Mark: If a triangle has a right angle mark (a small square) on one of its angles, then it is a right-angled triangle.

By using any one of the above methods, you can determine whether a triangle is a right-angled triangle or not.

So, Question no 6

Let the distance between three cities be a, b and c i.e. 45 miles, 56 miles and 72 miles.
using Pythagoras theorem,
a^2 + b^2 = c^2
45^2+56^2=72^2
2025+3136=5184
5161=5184

Hence, It's not a right-angled triangle.

So, Question no 7 has three sides a, b and c i.e. 4 ft, 3 ft and 5 ft.
using Pythagoras theorem,

a^2 + b^2 = c^2
4^2+3^2=5^2
16+9=25
25=25
Hence, it's a right-angled triangle.

Question no 8 also have three sides a, b and c i.e. 5 in, 12 in and 13 in.
using Pythagoras theorem,

a^2 + b^2 = c^2
5^2+12^2=13^2
25+144=169
169=169
Hence, it's a right-angled triangle.

Question no 9 also have three sides a, b and c i.e. 9.5 feet, 16 feet and 18.5 feet.
using Pythagoras theorem,

a^2 + b^2 = c^2
9.5^2+16^2=18.5^2
90.25+256=342.25
346.25=342.25
Hence, It's not a right-angled triangle.

The angles are;

A = 60

B = 38

C = 82

The cosine rule is a mathematical formula used in trigonometry to determine the lengths of sides of a triangle, given the lengths of two sides and the measure of the angle between them. The cosine rule states that the square of the length of a side of a triangle is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the lengths of those sides and the cosine of the angle between them.

c^2 = a^2 + b^2 - 2abCos C

7^2 = 5^2 + 8^2 - 2(5 *8) Cos C

49 = 25 + 64 - 80 CosC

-40  = -80 CosC

Cos C = 0.5

C = 60°

b^2 = a^2 + c^2 - 2ac Cos B

5^2 = 8^2 + 7^2 - 2(8 *7) Cos B

25 = 64 + 49 - 112Cos B

Cos B = 38

C = 180 - (60 + 38)

A = 82

Answer:

Step-by-step explanation:

divide by 6

2k+8=-8

subtract 8 in both sides

2k=-16

divide by 2

k=-8

equal to -8

In order to solve for k you always want to try and isolate the variable (trying to get only k on one side of the equal sign). You can start of by distributing 6 into the numbers in the parenthesis. So 6 times 2k is 12k and 6 times 8 is 48. So in reality, you now have 12k+48= -48. Then you can subtract 48 from the left side to cancel it out. Note: you would not add 48 to cancel out the -48 on the right because you need a number on both sides of the equal sign. So once you subtract -48 from one side you must do it to the other so -48-48 is -96. Now you have 12k=-96. All you have to do now is cancel out the 12k but dividing since it is the inverse of multiplying. Divide 12 from both sides and -96 divided by 12 is -8.

So your answer is k=-8
