Eight angles of a nonagon measure 1389, 154º. 145°, 132°, 148°, 143,
147°and 150°. What is the measure of the ninth angle?

Answers

Answer 1

Answer:

103°

Step-by-step explanation:

The total angle in a nonagon is 1260. To get the missing angle, we add up all the given angle together and subtract it from 1260.

138 + 154º + 145° + 132° + 148° + 143 + 147 + 150 = 1157

1260 - 1157 = 103

Therefore, the missing angle is 103°

In a video game, a guppy that escapes a net turns into three goldfish. Each goldfish can turn into two betta fish. Each betta fish can turn into two angelfish. Complete the diagram and write the number of fish at each stage. Write and evaluate an expression for the number of angelfish that can be formed from one guppy

Answers

Answer: 1 guppy = 3 goldfish

1 goldfish = 2 betta fish.....so 3 goldfish = (3 * 2) = 6 betta fish

1 betta fish = 2 angel fish....so 6 beta fish = (6 * 2) = 12 angel fish

so the number of angelfish that can be formed by 1 guppy is 12 angelfish

PLEASE HELP- A triangle has vertices A(0, 0), B (9, 4), and C(–2, 10). What are the coordinates of the triangle after a dilation with a scale factor of 1/2 ?

Answers

Basically multiply the x and y coordinates of each point by 1/2

For example, I'll do C which is ( -2 , 10 )

-2 * 1/2 = -1 and 1/2 * 10 = 5

The new coordinate is ( -1 , 5 )

Formula of area

AREA = LENGTH (multiply) BREATH

Answer:

The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.

In this case, 4 is the base, and 7 is the height.

So we have: Area = 1/2(4)(7)

Simplifying: Area = 2(7), Area = 14.

The area of the triangle is 14 meters squared.

Draw the graph of the equation x − y = 4
Answer the following using graph paper:
(i) Find the value of y, if x = 7 from the graph.
(ii) Write the coordinate of the point where the graph intersect on x − axis.

Answers

Answer:

We have the equation:

x - y = 4

We can write this as a linear equation in the slope-intercept form if we isolate the variable y.

We get:

y = x - 4

Now to graph this function, we need to evaluate x in two different points and get two points (x, y) of the line.

If we use x = 1 and x = 2, then we get:

y(1) = 1 - 4 = - 3

Then we have the point (1, -3)

and:

y(2) = 2 - 4 = - 2

Then we have the point (2, - 4)

Now we need to draw these two points in the coordinate axis, and draw a line that connects the points, the example can be seen in the image below.

a) To use the graph, we need to locate the value x= 7 in the x-axis.

Then draw a vertical line

In the point where the vertical line intersects the graph, we draw an horizontal line.

The y-value will be the value at which this horizontal line intersects the y-axis

In this case, is at  y = 3.

Then when x = 7, y = 3.

(you can see it in the graph)

ii) The coordinate at which the graph intersects the x-axis can be seen in the graph, it is the point (0, 4)

What is a triangle?

A triangle is a two dimensional shape bound by three sides. The sum of the interior angles of a triangle is 180°. The longest side of a triangle is always less than the sum of other two sides.

For the given diagram, the following data is given as,

Base of the upper and lower triangle is 6.5 + 2.5 = 9 yards.

And, the height is given as 6 yards.

Now, the area of the land can be given as,

Area of upper triangle + Area of lower triangle

⇒ 1/2 × 9 × 6 +  1/2 × 9 × 6

⇒ 54 square yards.

As per the question, the area of the land is more than the soil contained in 1 bag.

Which implies the number of bags required is given as 2.

Hence, the area of land and number of bags required is obtained as  54 square yards and 2 respectively.
