Step-by-step explanation:

Simply use the general equation of a circle to obtain its equation given the center. Because radius is 5 units, this may be referred to the 3-4-5 triangle, meaning the point on circumference is 3 units across in the x-direction and 4 units up in the y-direction.

80 square units
Divide the figure into 4 small triangles, 2 rectangles, and one big rectangle on the center.

Area of ONE small triangle:
1/2 • 2 • 2 = 2 square units
Multiply that by 4 because we have 4 small triangles: 2 • 4 = 8 square units

Area of ONE small rectangle:
2 • 6 = 12 square units
Multiply that by 2 bcos we have 2 of those rectangles: 12 • 2 = 24 square units

Area of the big rectangle on the center:
6 • 8 = 48 square units

ADD the area of the big rectangle, 4 small triangles, and 2 small rectangles:
48 + 24 + 8 = 80

FINAL ANSWER: 80 square units

A vacant lot is being converted into a community garden. The garden and and a walkway around its perimeter have an area of 460 s

mariarad [96]

Answer:

The width of the walkway is 4 feet.

Step-by-step explanation:

The garden and a walkway around its perimeter have an area of 460 square feet.

The length of the garden = 15 feet

The width of the garden = 12 feet

Assuming that walkway is of uniform width, we can solve the following equation.

$(12+2x)\times(15+2x)= 460$

Expanding this we get;

$4x^{2}+54x+180=460$

$=> 4x^{2}+54x-280=0$

We will solve this using quadratic equation formula:

$x=\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}$

Here a = 4 , b = 54 , c = -280

We get the roots as x = 4 and x = $-\frac{35}{2}$

Neglecting the negative value, we will take x = 4 feet.

Hence, the width of the walkway is 4 feet.

two angles are consecutive exterior to one another. if the angles are in ratio 11:7. Then find the supplement of the larger angl

Gwar [14]

If the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be 70 degrees.

The larger angle and the smaller angle are supplementary to each other since they are consecutive exterior to one another.

Thus:

If the larger angle is x, therefore:

Ratio of Larger angle to smaller angle = 11:7

Therefore:

11x + 7x = 180 degrees

Solve for x

18x = 180

Divide both sides by 18

x = 10

Larger angle = 11x = 11(10) = 110 degrees

Smaller angle = 7x = 7(10) = 70 degrees

The supplement of the larger angle, 110 degrees, is 70 degrees.

In summary, if the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be 70 degrees.
