HOW IS THE INSCRIBED QUADRILATERAL PROOF WRITTEN?

Answers

Answer 1

Answer:

In the quadrilateral ABCD can be inscribed in a circle, then we have seen above using the inscribed angle theorem that the sum of either pair of opposite angles = (1/2(a1 + a2 + a3 + a4) = (1/2)360 = 180.

1.11111111111 cups of rice will fill an empty jar of the same size.

Step-by-step explanation:

⅗ jar = ⅔ cups

1 jar = ? cups

⅗ = 0.6    &    ⅔ = 0.66666666666

\((\frac{cups}{jar})\)  →  \(\frac{0.66666666666}{0.6}\) = 1.11111111111

Answers

62 in squared

The area of one rectangular side is 2.5x7 = 17.5
There are two of these rectangles so 17.5 x 2 = 35

The bottom rectangle has an area if 3x7=21
The triangles each have an area of (2x3)/2=3

Add up all the areas calculated and you get:
35+21+3+3 = 62 for the surface area

Answer:

the answer is 62 in. 2

Step-by-step explanation:

(the base is the triangle)

base:2*3/2 * 2 = 6
sides: 2.5*7*2 = 35
bottom: 3*7 = 21

base+sides+bottom
= 6+35+21
=62 in. 2

8% equals .08

24 hours x 60 minutes = 1440 minutes

1440 x .08 = 115.2

When in doubt you can check. Do this to each section, add up and make sure you 1440.

Answer:

Avery spends an approximate number of 115.2 minutes each day on extracurricular activities.

Step-by-step explanation:

1 day = 24 hour     60min = 1 hour

24 × 60 = 1440 (1440min in a day)

Extracurricular activities: 8%

\(\frac{8*1440}{100}\) = \(\frac{11520}{100}\) (divide 11520 by a hundred) = 115.2

Leon is scuba diving at an elevation of −72
feet when his friend signals to come higher to see a sea turtle. Leon makes 3 ascents, each an equal distance, to reach an elevation of −18
feet, where the sea turtle is located.

What was Leon's elevation after his second ascent?

Answers

Answer: -36 feet

Step-by-step explanation:

72-18 = 54 feet ascended

54 feet / 3 ascents = 18 feet per ascent

18 feet * 2 ascents = 36 feet

-72+ 36 = -36 feet

After his second ascent Leon was at an elevation is -36. Step by step; 72-18= 54
54/3= 18, 18*2=36

PLEASE HELP!!! Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages

Use a number line to order the numbers from least to greatest.

Use a number line to order the numbers from least to greatest.

Answers

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

9/4=2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

The price was $250. Now its 100 find the percentage change

Answers

Answer:

Step-by-step explanation:

The formula for percent change is

\(\frac{original-new}{original}*100\)

Therefore,

\(\frac{250-100}{250}*100=60\)%

Answer: 60%

Step-by-step explanation:250 - 100 = 150

150/250 = 60/100 = 60%

(Will give 15 points)Solve the system of linear equations by substitution. x + y = 7 and 7x + y = 1

Answers

Answer:

(-1, 8)

Step-by-step explanation:

Make y the subject:

x + y = 7 ⟹ y = -x + 7

1. Substitute the value for y into 7x + y = 1 and solve for x:

7x + (-x + 7) = 1

7x - x + 7 = 1

6x + 7 = 1

6x + 7 - 7 = 1 - 7

6x = -6

6x ÷ 6 = -6 ÷ 6

x = -1

2. Substitute the given value of x into x + y = 7 and solve for y:

x + y = 7

-1 + y = 7

-1 + 1 + y = 7 + 1

y = 8

Therefore, the solution to this system of equations is: (-1, 8).

You want the equations for the inequalities shown on the graph.

Line A

The downward sloping dashed line crosses the y-axis at y=3. It has a "rise" of -2 units for each 1 unit to the right. Its slope is rise/run = -2/1 = -2.

The equation for this boundary line can be written ...

The graph is shaded above this line, which is not included in the solution. The inequality graphed is ...

  y > -2x +3

Line B

The upward sloping solid line crosses the y-axis at y=0 and has a rise of 1 for each run of 1 unit to the right. Its slope is 1/1 = 1, and its y-intercept is 0.

The equation for the boundary line can be written ...

  y = 1x +0

The graph is shaded below the solid boundary line, so the boundary is included in the solution. The inequality graphed is ...

  y ≤ x
