Problem 1) 40 degreesProblem 2) 84 degreesProblem 3) 110 degrees

===============================================

Explanation:

For these questions, we'll use the inscribed angle theorem. This says that the inscribed angle is half the measure of the arc it cuts off. An inscribed angle is one where the vertex of the angle lies on the circle, as problem 1 indicates.

For problem 1, the arc measure is 80 degrees, so half that is 40. This is the measure of the unknown inscribed angle.

Problem 2 will have us work in reverse to double the inscribed angle 42 to get 84.

-------------------

For problem 3, we need to determine angle DEP. But first, we'll need Thales Theorem which is a special case of the inscribed angle theorem. This theorem states that if you have a semicircle, then any inscribed angle will always be 90 degrees. This is a handy way to form 90 degree angles if all you have is a compass and straightedge.

This all means that angle DEF is a right angle and 90 degrees.

So,

(angle DEP) + (angle PEF) = angle DEF

(angle DEP) + (35) = 90

angle DEP = 90 - 35

angle DEP = 55

The inscribed angle DEP cuts off the arc we want to find. Using the inscribed angle theorem, we double 55 to get 110 which is the measure of minor arc FD.

The perimeter of a right-angled triangle is 96 cm.
The lengths of its sides are in the ratio 6:8:10
Work out the area of the triangle in cm”.
B x W x = 2
Total marke: 4

Answers

Answer:

[tex]A=384\ cm^2[/tex]

Step-by-step explanation:

Let the sides of a triangle be 6x,8x and 10x.

Perimeter of the triangle, P = 96 cm

We need to find the area of the triangle.

P = sum of all sides

6x+8x+10x = 96

24x = 96

x = 4

Sides are :

6x = 6(4) = 24 cm

8x = 8(4) = 32 cm

10x = 10(4) = 40 cm

Area,

[tex]A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 24\times 32\\A=384\ cm^2[/tex]

So, the area of the triangle be [tex]384\ cm^2[/tex].

A certain forest covers an area of 4800 km^2 . Suppose that each year this area decreases by 5.25% . What will the area be after 6 years? Use the calculator provided and round your answer to the nearest square kilometer.

Answers

Answer:

the area after 6 years is 3,473 km^2

Step-by-step explanation:

The computation of the area after 6 years is as follows:

= Area × (1 - decreased percentage)^number of years

= 4,800 km^2 × (1 - 5.25%)^6

= 4,800 km^2 × 0.9475^6

= 3,473 km^2

Hence, the area after 6 years is 3,473 km^2

Whatis the answer to the problem

Answers

Answer:

slope = [tex]-\frac{1}{8}[/tex]

Step-by-step explanation:

Use the slope formula given in the question to solve for the slope. The [tex]m[/tex] is the variable representing the slope. The [tex]x_1[/tex] and [tex]y_1[/tex] values are x and y values of one point. The [tex]x_2[/tex] and [tex]y_2[/tex] are x and y values of another point.

So, use the x and y values of the points given and substitute them in the correct order into the formula:

[tex]m = \frac{(7)-(9)}{(10)-(-6)}\\m = \frac{7-9}{10+6} \\m = \frac{-2}{16} \\m = -\frac{1}{8}[/tex]

Thus, the slope is [tex]-\frac{1}{8}[/tex].

Work out

Answers

Answer:2

Step-by-step explanation:

For line y = 9x, m = 9 and c = 0

What is the slope-intercept form of the line?

"y = mx + c, where m is the slope of the line and c is the y-intercept of the line."

What is slope of the line?

"It is the change in y coordinate with respect to the change in x coordinate."

What is y-intercept?

"It is a point at which a line intersects the Y-axis."

For given question,

We have been given an equation of line y = 9x

By comparing above equation of line with the slope-intercept form of line,

m = 9 and c = 0

This means the slope of the line y = 9x is 9 and the y-intercept is 0

Therefore, for line y = 9x, m = 9 and c = 0

What is the mean of the values in the dot plot?

Enter your answer in the box.

Answers

Answer:

The mean is 46.

Step-by-step explanation:

To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.

40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50

Multiply what's in the parentheses.

40 + 82 + 45 + 96 + 147 + 50

Add, going from left to right

122 + 45 + 96 + 147 + 50

167 + 96 + 147 + 50

263 + 147 + 50

410 + 50

460

Now, divide that by how many dots there were (10).

460/10

The mean of the values in this dot plot is 46.
