Answer:

62.84 m

Step-by-step explanation:

6*3.14 = 18.84

12*2 = 24

10*2 = 20

total: 62.84

The solution is 62.84 m

The perimeter of the figure is P = 62.84 m

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the perimeter of the figure be represented as P

Now , the figure has a semi circle , a square and a triangle

The side of the square = 12m

So , the number of sides of square in the perimeter of the figure = 2 sides

So , perimeter of 2 sides = 2 x 12 = 24 m

Now , the 2 sides of the hypotenuse of the right triangle is also part of the figure , so

perimeter of 2 sides of the triangle = 2 x 10 = 20 m

Now , the total perimeter of figure = perimeter of the semi circle + 24 + 20

Perimeter of semi circle = 2πr / 2

The radius of the circle = 6 m

Substituting the value of r in the equation , we get

Perimeter of the semi circle = ( 2 x 3.14 x 6 ) / 2

Perimeter of the semi circle = 18.84 m

So , the perimeter of the figure P = 18.84 m + 24 m + 20 m

The perimeter of the figure P = 62.84 m

Therefore , the value of P is 62.84 m

Hence , The perimeter of the figure is P = 62.84 m

The probability that a point is chosen at random in the shaded region will be 0.25.

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

Probability = (Favorable event) / (Total event)

The area of the shaded circle below is 78.5 square inches.

The area of the large circle is 314 square inches.

A shaded circle is inside of a larger unshaded circle.

Then the probability that a point is chosen at random in the shaded region will be

P = 78.5 / 314

P = 1 / 4

P = 0.25

Then the correct option is A.

Answer:

B. x ≤ 5

Step-by-step explanation:

This is an inequality problem. It can be solved by examining the arrow and the point it closes on. If the arrow is going left, then all values of x are going to be less than the point it closes on. If the arrow is going right, then all values of x are going to be greater than the point it closes on.
If the circle on the point the arrow is closed/shaded in, then that value will be included in the values of x, giving the inequality either a ≤ or ≥ sign depending on which way the arrow is pointing. If the circle on the point the arrow is open, then that value will not be included in the values of x. The sign will be either < or >.

---------------------------------------------------------------------------

For this problem, the arrow is going to the left of 5, which means all values of x are going to be less than 5. Because the circle is closed, that means that number 5 is included, or x can be equal to 5. If the circle was open, it wouldn't be included. So, the inequality is x ≤ 5.

If the radius of the cylinder is 47 feet. Then the volume of the cylinder will be 277,450.4 cubic feet.

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

Jerry, Skyler, and kyle were measuring the tank (cylinder) for storing the water tower on the hill.

Working together jerry and Skyler determine the circumference was approximately 295.3 feet.

Kyle measured the height to be about 40 feet.

Then the volume of the cylinder will be

Volume = πr²h

Then the value of r will be

We know the circumference. Then the radius will be

295.3 = 2πr

       r = 47 ft

Then we have

Volume = π x 47² x 40

Volume = 277,450.4 cubic ft

Answer:

Function 2 shows a greater rate of change, because Edwin spends $9 each month and Adam spends $7 each month.

I found this out because for Adam, you simply subtract the y-coordinates from each other and get 7 each time. Edwin clearly shows that he Spends $9 each month with the negative sign.

Step-by-step explanation:

Answer:

Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.

Step-by-step explanation:

Function 1

Money remaining in Galvin's money box:

[tex]\begin{tabular}{| c | c |}\cline{1-2} Number of Months (x) & Amount Remaining (in \$) (y)\\\cline{1-2} 1 & 80\\\cline{1-2} 2 & 75 \\\cline{1-2} 3 & 70 \\\cline{1-2} 4 & 65 \\\cline{1-2}\end{tabular}[/tex]

We can calculate the rate of change by using this formula:

[tex]\textsf{rate of change}=\dfrac{\textsf{change in y}}{\textsf{change in x}}[/tex]

[tex]\implies \textsf{rate of change}=\dfrac{75-80}{2-1}=\dfrac{-5}{1}=-5[/tex]

Therefore, The rate of change of function 1 is -5 which means that Galvin spends $5 per month.

Function 2

Money remaining in Henry's money box:  

[tex]\sf y = -7x+80[/tex]

This is represented as a linear equation: y = mx + b
(where m is the slope or "rate of change" and b is the y-intercept of "initial value)

Therefore, the rate of change of function 2 is -7 which means that Henry spends $7 per month.

Conclusion

Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.
