Answer:

28.26 u²

Step-by-step explanation:

What we know:

A circle has a circumference of 18.84 u.

That means the diameter is 6, and the radius is 3.

The area of a circle can be found with: πr²

3.14(3²)

3.14(9)

28.26 u²

The area of the circle is 28.26 square units when the circumference of circle is 18.84 units.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The circumference of the circle is 18.84 units

We have to find the area of circle

To find area we need to know the radius

Circumference of circle = 2πr

18.84 = 2πr

18.84 = 2×3.14 r

18.84=6.28 r

Divide both sides by 6.28

r=18.84/6.28

r=3

Now let us find area

Area = πr²

=3.14×3²

=9×3.14

=28.26 square units

Hence, the area of the circle is 28.26 square units when the circumference of circle is 18.84 units.

Answer:

4.8 smaller pieces

Step-by-step explanation:

Total length of wood = 3.6 feet

Length of each piece = 0.75 feet

How many smaller pieces will they be able to make?

Number of smaller pieces of wood = Total length of wood / Length of each piece

= 3.6 feet / 0.75 feet

= 4.8 smaller pieces

Number of smaller pieces of wood = 4.8

Answer:

y=3/4x-3

Step-by-step explanation:

Okay so to be parallel to an equation of another line, the line must have the same slope but a different y-intercept. First, you need to find the slope of the equation -3x+4y=4. The equation must be in y=mx+b format, so you first move -3x to the right by adding it on both sides, leaving you with 4y=3x+4. Next, you divide 4y by 4 in order to isolate y and do that on the other side. Now, you have y=3/4x+1.

To find the equation of the new line, you must put the point and slope into point slope form: y-y1=m(x-x1). In the point (4, 0), 4 would be x1 and 0 would be y1. so, the new equation is y-0=3/4 (x-4). now, distrubute the 3/4, leaving you with y=3/4x-3. This is correct since the slope remains the same in both equations with a different y-intercept. To check deeper, you could place point (4, 0) on a graph and then rise 3, run 4 until you get the line :) hope this helps

Answer:

8m⁵

Step-by-step explanation:

m to the 5th power = m × m × m × m × m

                                = m⁵

Then multiplied by 8 = 8 × m⁵

                                   = 8m⁵

Therefore, m to the 5th power multiplied by 8 will be represented by 8m⁵.

Answer:

47.3feet

Step-by-step explanation:

The set up will give a right angled triangle.

The distance of the dog away from the cliff = 130 feet = adjacent side

Angle of depression = 20°

Height of the cliff = Opposite = x

Using the SOH, CAH, TOA trigonometry identity;

According to TOA;

tan theta = opposite/adjacent

tan 20 = x/130

Cross multiply;

x = 130tan20

x = 130(0.3639)

x = 47.3 feet

Hence the height of the cliff to the nearest tenth is 47.3feet

Answer:

True

Step-by-step explanation:

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide both sides by 5

x = 3

Plug this number into the next equation and see if it is true

10x + 4 = 34

10(3) + 4 = 34

30 + 4 = 34

34 = 34

This is a true equation, so the the answer is true.

Answer:

True

Step-by-step explanation:

⇒ This is true because the whole equation 10x + 4 = 34 is 2 times more than the other equation 5x + 2 = 17.

⇒ You can see that by multiplying the whole equation 5x + 2 = 17 by 2:

2(5x + 2 = 17)

⇒ To get:

10x + 4 = 34

So both equations are equivalent, which means that the answer is true.

If two angles sum is equal to 90° and makes right angle called = complementary angle...☺️✌️

Above sum solution....

one angle =x

other angle =y

According to question

x+y= 90°......(1)

x-y=22°......(2)

from one and two ....by eliminating method...

2y=68

y=68/2

y=34

put y in equation 1

x+y=90°

x+34=90°

x=90°-34

x= 56...

To verify add both

sum = 90°

Hence ..verified...

48√2 in the simplest form of the expression √192.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can simplify the √192 by factoring it into its prime factors:

192 = 2 × 2 × 2 × 2 × 2 × 3 × 3

Then, we can group the prime factors into pairs of two:

192 = (2 × 2) × (2 × 2) × (2 × 3) × 3

Simplifying each pair of factors under the square root gives:

[tex]\sqrt{192} = \sqrt{(2\times2)}\sqrt{(2\times2)}\sqrt{(2\times3)}\sqrt{3}\\= 4\times4\times\sqrt{6}\sqrt{3} \\= 16\sqrt{6}\sqrt{3}[/tex]

Finally, we can simplify the expression by multiplying the coefficients and combining the square roots:

[tex]16\sqrt{6}\sqrt{3} \\= 16\sqrt{18} = 16\sqrt{2\times3\times3} \\= 16\times3\sqrt{2} \\= 48\sqrt{2}[/tex]

Therefore,

48√2 in the simplest form of the expression √192.
