Answer:

i believe it is 231 yd squared

Step-by-step explanation:

Answer:

1. 231 yd²

2. 78 ft²

3. 28 inches

4. 57.5 centimeters

5. 258 cm²

Step-by-step explanation:

That is not geometry, but here are your answers.

A = bh

A = 13.2 × 17.5

A = 231 yd²

[tex]A=\frac{bh}{2}[/tex]

[tex]A=\frac{(13)(12)}{2}[/tex]

[tex]A=\frac{156}{2}[/tex]

A = 78

[tex]b=2\frac{A}{h}[/tex]

[tex]b=2\frac{364}{28}[/tex]

b = 28

[tex]h=2\frac{A}{a+b}[/tex]

[tex]h=2\frac{5405}{65+123}[/tex]

[tex]h=2\frac{5405}{188}[/tex]

[tex]h=2(28.75)[/tex]

h = 57.5

A = a²

A = 12²

A = 144 cm²

12 ÷ 2 = 6

[tex]A=\frac{(h)(b)}{2}[/tex]

[tex]A=\frac{114}{2}[/tex]

A = 57

57 cm² + 57 cm² = 114 cm²

114 cm² + 144 cm² = 258 cm²

The running tracks of two different playgrounds are shown below. Figure A is a semicircle with a diameter of 100 m. Figure B is composed of two semicircles and a square with sides of 100 m. How much farther would an athlete run if they ran around the track in Figure B vs. the track in Figure A?

Answers

Answer:

10157.08 m

Step-by-step explanation:

Find the area of the square, and get 10000, from multiplying 100 by 100. Then, find the circumference/area of the semi-circle as a whole circle. 314.16m. Divide it by 2 and get 157.08 m. Add everything up and get 10157.08 m. Remember, that we aren't calculating the total of both semi-circles because we subtract Figure A from Figure B.

Measure of missing angle

Answers

Answer:

44 degrees.

Step-by-step explanation:

Since angle A is 46 degrees, and angle C is 90 degrees (because of the right angle) you add 46 and 90 (you get 136) then subtract it from 180 (since every triangle equals 180 degrees) which gets you to 44 degrees.

Answer:

The ordered pairs are (-2,-5) (-1,-4) (0,-3) (1,-2)(2,-1)

Step-by-step explanation:

Simply subtract 3 from each x value.

Next, graph the equation using the ordered pairs I gave you.

Just put a dot for each of the ordered pairs on a table and connect them into a straight line.

The ordered pairs are (-2,-5) (-1,-4) (0,-3) (1,-2)(2,-1) through which we draw the attached graph.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given equation of the line is y=x-3

Slope of given equation is 1.

We need to find the values of y when x is -2, -1, 0 , 1 and 2 to fill the table.

When x=-2

y=-5

The order pair is (-2, -5)

At x=-1

y=-4

The order pair is (-1, -4)

When x=0

y=-3

The order pair is (0, -3)

When x=1

y=-2

The order pair is (1, -2)

When x=2

y=-1

The order pair is (2, -1)

Hence, the ordered pairs are (-2,-5) (-1,-4) (0,-3) (1,-2)(2,-1) through which we draw the attached graph.

As a decimal your answer: is 5.4 rounded to the nearest tenth. As a mixed number fraction your answer is: 5 11/25. As a improper fraction your answer is: 136/25.

Step-by-step explanation:

Basically what I did was just divide 6.8 by 4/5. Or you could change 4/5 in a decimal and divide like that, OR change 6.8 into a fraction which is what if did- I’ll show you below. But, it’s better to have all solutions to the problem.

1) change 6.8 into fraction: 34/5

2) rewrite: 34/5 divide by 4/5

3) multiply: 136/25

4) alternative forms:
