Write the standard form of the equation of the circle.

Answers

9514 1404 393

Answer:

  (x +4)^2 +(y +6)^2 = 18

Step-by-step explanation:

The standard form equation for a circle centered at (h, k) with radius r is ...

  (x -h)^2 +(y -k)^2 = r^2

The center of the given circle is (-4, -6). The radius (or squared radius) can be found by putting the point (-7, -3) into the left-side expression.

  (-7 -(-4))^2 +(-3 -(-6))^2 = r^2 = 9 +9 = 18

Then the equation of the circle is ...

  (x +4)^2 +(y +6)^2 = 18

Find the measures of the indicated angle in the parallelogram

Answers

The internal angles of a parallelogram add to 360 degrees. A parallelogram must have equivalent opposite interior angles. Therefore angles a and c are the same and angles b and d are the same. We now know that angles a and c add to 102 degrees so we do (360-102)/2. Which is 129 degrees for both angles. The answer is 129 degrees for angle b

Two sides of an isosceles triangle are 4 and 8. Which of the following choices could be the measure of the third side?

B. 8
C. 6
D. 4

Answers

Answer:

8 is answer. isoceles triangles must have two equal sides, where the smaller makes the base and the two larger are the legs.

Step-by-step explanation:

The measure of the third side of an isosceles triangle is 8 units.

What is an isosceles triangle?

An isosceles triangle is a triangle with (at least) two equal sides. A polygon that consists of two equal sides, two equal angles, three edges, three vertices and the sum of internal angles of a triangle equal to 180°.

For the given situation,

The sides of an isosceles triangle are 4 and 8.

In isosceles triangle, two sides have equal length and the base should be less.

From the measurements given, the base could be 4 units and the third side is same as 8 units.

Hence we can conclude that the measure of the third side of an isosceles triangle is 8 units.

Can someone solve for x? And maybe explain it in a simple way?

Answers

Answer:

x=10

Step-by-step explanation:

Because of the two parallel lines, the ratio between the sides must be the same.  Since the bottom is 12 to 18 (a ration of two to three) we know that x and x+5 would have the same ratio.  Logically, x would have to equal 10 so that x+5 would equal 15 and a ratio of two to three would exist there too.  If you go to solve a problem and the answer isn’t obvious, jut set up a ratio.

12/18=x/(x+5)

then cross multiply and solve

12(x+5)=18x

12x+60=18x

60=18x-12x

60=6x

10=x

Answer:

x=10

Step-by-step explanation:

You can set it up as a proportion, since the lines are parallel, the sections are proportionate to each other.

[tex]\frac{x}{12} = \frac{x+5}{18} \\18x=12(x+5)\\18x=12x+60\\6x=60\\x=10[/tex]

7x + 9 = 58? solve for x

Answers

Answer: x=7

Answer Explanation: 7x=58-9...
58-9 is 49...
7x=49...
Divide 49 by 7 and you get 7.

The solution to the equation 7x + 9 = 58 is x = 7.

To solve the equation 7x + 9 = 58 for x, we can follow these steps:

Subtract 9 from both sides of the equation to isolate the term with x:

7x + 9 - 9 = 58 - 9

7x = 49

Divide both sides of the equation by 7 to solve for x:

7x / 7 = 49 / 7

x = 7

Therefore, the solution to the equation 7x + 9 = 58 is x = 7.

The courtyard outside East Middle School is in the shape of a rectangle and half-circle.
What is the approximate area of the courtyard?

Answers

Answer:

The correct option is the third one counting from the top. (5892 m^2)

Step-by-step explanation:

First, we need to remember that:

For a rectangle of length L and width W, the area is:

A = L*W

For a circle of diameter D, the area is:

A = pi*(D/2)^2

Where pi = 3.14

In the image, we can see a rectangle and half a circle, the total area of the image will be equal to the area of the rectangle plus the area of the half circle.

In the image, we can see a rectangle of length L = 100m and width W = 50m

Then the area of the rectangle is:

A = 100m*50m = 5000m^2

And we can see that for the half-circle the diameter is D = 50m

Note that the area of a half-circle is half of the area of a complete circle, then the area of that half-circle is:

A = (1/2)*(3.14*(50m/2)^2) = 981.25 m^2

If we add these two areas we get:

Total area =  5000m^2 + 981.25 m^2 = 5981.25 m^2

If we round it up, we get:

Total area = 5982 m^2

The correct option is the third one counting from the top.

(Round to the nearest hundredth as needed.)

Answers

Answer:

The area of the reference section excluding its storage area is approximately 157.78 square feet.

Step-by-step explanation:

The area of the reference section excluding its storage area ([tex]A[/tex]), in square feet, is the area of the greater circular sector minus the lesser circular sector, that is:

[tex]A = \frac{1}{2}\times \frac{45^{\circ}}{180^{\circ}} \times \pi \times (37.5\,ft)^{2} - \frac{1}{2}\times \frac{45^{\circ}}{180^{\circ}}\times \pi \times (12\,ft)^{2}[/tex]

[tex]A \approx 157.781\,ft^{2}[/tex]

The area of the reference section excluding its storage area is approximately 157.78 square feet.

What are m21 and m_2?

Answers

Answer:

<1  = 35degrees

<2  = 30degrees

Step-by-step explanation:

Using the theorem that the sum of external angle is equal to sum of interior angle

Considering the smaller triangle

Exterior angle = 115 degrees

Sum of interior = <1 + 80

Equating both

<1 + 80 = 115

<1 = 115 - 80

<1  = 35degrees

For the big rectangle

Exterior angle = 115 degrees

Sum of interior = <2 + 85

Equating both

<2 + 85 = 115

<2 = 115 - 85

<2 = 30degrees

A book costs $1.49 and is sold in a retail store for $8.99. What is the percentage in mark up? mmnle 10 percent would be 10% You can find the percent​

Answers

Answer:

The percentage in mark up is 503.56%.

Step-by-step explanation:

The percentage in markup is the change(retail - cost) divided by the initial cost, and multiplied by 100%.

In this question:

Cost: 1.49

Change: 8.99 - 1.49 = 7.5

Percentage change:

(7.5*100%)/1.49 = 503.56%.

The percentage in mark up is 503.56%.
