Answer:

a = 72° b = 88°

Step-by-step explanation:

We know in the cyclic quadrilateral opposite angles are supplementary so

a + 108° = 180° { being opposite angles of cyclic quadrilateral }

a = 180° - 108°

a = 72°

b + 92° = 180° { being opposite angles of cyclic quadrilateral }

b = 180° - 92°

b = 88°

Answer:

25 degrees

Step-by-step explanation:

So a triangles angels equal 180 degrees

So for angel ECD 180 - (15+90) = 75

Straight lines also always equal to 180 degrees so

180 - (80+75) = 25

Measure of ∠BCE = 25° .

A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.

Given, In figure,

∠CED = 15°

∠EDC = 90°

∠BCA = 80°.

In triangle ECD

Sum of all interior angles of a triangle is 180°

∠ECD +∠CED +∠EDC = 180°

∠ECD + 15° + 90° = 180°

∠ECD = 180° - 105°

∠ECD = 75°

Now,

∠BCA,∠BCE and∠ECD are at point C on line AD.

Sum of all angles made at one point of line is 180°.

∠BCA +∠BCE +∠ECD = 180°

80° + ∠BCE + 75° = 180°

∠BCE = 180° - 155°

∠BCE = 25°

Hence, 25° is measure of ∠BCE.

Answer: Choice A.  (8, 4)

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

Explanation:

Because x = 2y, we can replace every copy of x with 2y

Let's do so in the second equation

3x - 4y = 8

3(x) - 4y = 8

3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y

6y - 4y = 8

2y = 8

y = 8/2 ..... divide both sides by 2

y = 4

Use this y value to find x

x = 2y

x = 2*4

x = 8

So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

Answer in your own words:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape. Which can also be used to calculate the dimensions of the new figure or the original figure by simply substituting the values in the same formula.  

• The scale factor of a dilated figure is denoted by 'r' or 'k'.

• If the scale factor is more than 1 (k > 1), the image is enlarged.

• If the scale factor is less than 1 (0< k <1), the image is contracted.

• If the scale factor is 1 (k = 1), the image remains the same.

• The scale factor cannot be zero.

Scale factor = k

Pre-image lengths: a, b  

(perimeter = 2a + 2b)

Image lengths: ka, kb

(perimeter = 2ka + 2 kb or k (2a + 2b))

Marissa needs to say that the perimeter of the image is the perimeter of the pre-image times the same scale factor.

area of the pre-image = ab

area of the image = (ka)(kb) or k^2 (ab) (The area of the image is the area of the preimage times the square of the scale factor)

Scale factor 5 (then repeat it with scale factor 6)

length of the pre-image = 3 x 4  

(perimeter = 2 (3 + 4) = 2(7) = 14)

length of the image = (3x5) x (4x5) = 15 x 20= 300

(perimeter = 2 (15 + 20) = 2 (35) = 70 or 14 x 5 = 70  

area of the pre-image = 3 x 4 = 12

area of the image = 15 x 20 = 300

12 x (5^2) = 12 x 25 = 300

Answer:

344 visitors

Step-by-step explanation:

Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as

y=14.1x+62.0

when the daily rainfall is 20 mm, the number of visitors

y = 14.1(20) + 62

= 282 + 62

= 344

It means that the expected number of visitors is 344 persons (to the nearest integer).

Answer:

65%

Step-by-step explanation:

so there were 20 total voters. 20-7 = 13 that did not vote for the tax

13/20= . 65 = 65%

Since Joe has read 30% of the book, that means that 14 pages is 70% of the book. That means that two pages equals 10%. Therefore, the book has 20 pages.

70% = 14

so 30% = 6

total pages = 14+6=20

Answer:

g(x) is horizontally stretched by a factor of 1/5

Step-by-step explanation:

Given

[tex]f(x) = x^2[/tex]

[tex]g(x) = (\frac{x}{5})^2[/tex]

Require

Determine the relationship between f(x) and g(x)

[tex]f(x) = x^2[/tex]

[tex]g(x) = (\frac{x}{5})^2[/tex]

Express g(x) in terms of f(x)

[tex]g(x)=f(\frac{x}{5})[/tex]

This can further be simplified as:

[tex]g(x)=f(\frac{1}{5}x)[/tex]

When a function is represented as:

[tex]g(x) = f(cx)[/tex]

Where c < 1,

Then the type of translation is a horizontal stretch (stretch in the x direction)

By comparison: [tex]g(x) = f(cx)[/tex] and [tex]g(x)=f(\frac{1}{5}x)[/tex]

[tex]c = \frac{1}{5}[/tex]

This means that: g(x) is horizontally stretched by a factor of 1/5
