(3/5)/2=(1/4)/x solve for x

Step 1) Divide the figure into shapes

Triangle: 9 x 10

Large rectangle: 8 x 17

Small rectangle: 5 x 9

Smaller rectangle (bottom): 4 x 6

Step 2) Find the area of each shape

Triangle: A = 1/2 x 9 x 10 = 45

Large rectangle: A = 8 x 17 = 136

Small rectangle: A = 5 x 9 = 45

Smaller rectangle (bottom): A = 4 x 6 = 24

Step 3) Add the areas together

A = 45 + 136 + 45 + 24 = 250 square kilometers

Hope this helps! :)

Answer:

Step-by-step explanation:

area = pi*radius*radius -> Radius =  [tex]\sqrt{\frac{area}{pi} }[/tex]

area: 63.585 m2

   -> radius = [tex]\sqrt{\frac{63.585}{3.14} }[/tex] = 4.5 m

area: 28.26m2

  -> radius = [tex]\sqrt{\frac{28.26}{3.14} }[/tex] = 3m

   -> diameter = 6m

area: 120.7016m2

  -> radius = [tex]\sqrt{\frac{120.7016}{3.14} }[/tex] = 6.2m

   -> diameter = 12.4m

area: 12.56m2

   -> radius = [tex]\sqrt{\frac{12.56}{3.14} }[/tex] = 2m

area: 482.8064m2

   ->radius = [tex]\sqrt{\frac{482.8064}{3.14} }[/tex] = 12.4m

area: 113.04 m2

   ->radius = [tex]\sqrt{\frac{113.04}{3.14} }[/tex] = 6m

Answer:

The answer is 40 degrees.

Step-by-step explanation:

Answer:

9 sides

Step-by-step explanation:

Two methods and the same answer = 9 sides

Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.

Method 2: Since the exterior angle 140 degrees, The sum of the interior angles = (2n - 4)* right angles. So 140n =(2n - 4)* right angles, or

140n =(2n - 4)*90, or

140n = 180n - 360, or

40n = 360, or

n = 9 sides.

Hence the number of sides is 9 sides.

Answer:

9

Step-by-step explanation:

The sum of the interior angle and the exterior angle = 180°

Thus the exterior angle of the polygon = 180° - 140° = 40°

The sum of the exterior angles of a polygon = 360°, thus

number of sides = 360° ÷ 40° = 9

Answer:

CD = 12.

Step-by-step explanation:

By the tangent-secant theorem:

AB^2 = AC * AD

8^2 = 4 * AD

AD = 64/4 = 16

Finally CD = AD - 4 = 12.

Answer:

D

Step-by-step explanation:

Because the angle with measure 29 degrees and n are a linear pair, their value must add up to 180 degrees. Therefore:

n+29=180

n=180-29

n=151 degrees, or answer choice D

Answer:

They are both correct

Step-by-step explanation:

tan A = opposite / adjacent = 3/4   >>> A= 36.9 deg

tan C = opposite / adjacent = 4/3   >>> C= 53.1 deg

cheak:

<B+ <A + <C = 180 deg

90 + 36.9 + 53.1 = 180

180 = 180

Answer:

Botn are correct

Step-by-step explanation:

Tan ratio can be obtained by opposite/adjacent

Both students are correct. They have different values only because they have taken different reference angles

Rhianna has taken angle A as the reference angle,

So tanA = opposite/adjacent = BC/AB

tanA = 3/4

Christopher has taken angle C as the reference angle,

So tanC = opposite/adjacent = AB/BC

tanC = 4/3

Answer:

This is a right triangle

Step-by-step explanation:

We will use the Pythagorean theorem

a^2 + b^2 = c^2

If this is true it is a right triangle

5^2 + 12^2 = 13^2

25+144 = 169

169 =169

This is true so this is a right triangle

Answer:

Correct option: (3) 45

Step-by-step explanation:

Let's call the length of the tangent 'T', the length of the external segment 'E' and the length of the internal segment 'A'.

If we have a secant and a tangent to a circle, we can use the following property:

T^2 = E * (A + E)

If the tangent is 14 inches and the external segment is 4 inches, we have that:

14^2 = 4 * (A + 4)

196 = 4A + 16

4A = 180

A = 45

Correct option: (3)

Answer:

4m^4 - 8/3m^2 n^2 + 4/9n^4

Step-by-step explanation:

(2m^2 - 2/3n^2)(2m^2 - 2/3n^2)

= 2m^2(2m^2 - 2/3n^2) - 2/3n^2(2m^2 - 2/3n^2)

= 4m^4 - 4/3m^2 n^2 - 4/3m^2n^2 + 4/9n^4

=  4m^4 - 8/3m^2 n^2 + 4/9n^4

Answer:

The slope-intercept form:

[tex]y = -3x +4[/tex]

Step-by-step explanation:

-To get the slope-intercept equation, you first need to find the slope by using this equation [tex]m = \frac{rise}{run}[/tex] (starting counting from the first point, to the second point) in order to get the slope. After you have the slope, you need to find the y-intercept ( y-intercept is where the line crosses the y axis of the graph, basically). So, to find that, you need look for the point that only crosses the y axis to get the y-intercept. After you have both the slope and y-intercept, you put it in slope-intercept form:

The two points I found from the following graph are:

[tex]( 1, 1)[/tex] and [tex](2, -2)[/tex]

Trick: Since the line of the graph shows that it is down (not up), Start counting down from point [tex]( 1, 1)[/tex] to point [tex](2, -2)[/tex]. Then, find the y-intercept:

[tex]m = \frac{-3}{1} = -3[/tex]

[tex]b = 4[/tex]

Use it to create a slope-intercept form:

[tex]y = mx +b[/tex] (where [tex]m[/tex] represents the slope and [tex]b[/tex] represents the y-intercept)

[tex]y = -3x +4[/tex]

So, therefore the slope-intercept form is [tex]y = -3x +4[/tex] .

Answer:

yes

Step-by-step explanation:

Answer:

It would be an obtuse scalene triangle.

EDITED TO ADD:

When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:

1) Square all 3 sides.

2) Sum the squares of the 2 shortest sides.

3) Compare this sum to the square of the 3rd side.

if sum > 3rd side²   Acute Triangle

if sum = 3rd side²   Right Triangle

if sum < 3rd side²   Obtuse Triangle

6^2 = 36

10^2 = 100

12^2=144

36 + 100 = 136 and this is less than 144 so it is an obtuse triangle.

Answer:

Phillipa rode the most in May and rode the least in March.

Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March  

Step-by-step explanation:

Given:

In April, Phillipa rode 13 . 5 + 8 . 7 + 11 . 1 miles on her bicycle. In March, she rode ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 miles, and in May, she rode 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) miles.

To find: the month when she rode the most and the month when she rode the least

Solution:

Distance travelled by Phillipa on her cycle in April = 13 . 5 + 8 . 7 + 11 . 1 = 65 + 56 + 11 = 132 miles

Distance travelled by Phillipa on her cycle in March = ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 = [tex]\frac{132}{2}=66[/tex] miles

Distance travelled by Phillipa on her cycle in May = 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) = 4 × 132 = 528 miles

So, she rode the most in May and rode the least in March

Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March  

Answer: 13 packages.

Step-by-step explanation:

This can be translated to:

Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical packages. What is the largest number of packages that Tim can do?

To solve this we must find the largest common factor between 39 and 13.

to do this, we divide the smaller number by different integers, and see if the result also divides the larger number into an integer.

13/1 =13 and 39/13 = 3

So 13 is the largest common factor.

This means that we can make 13 packages, each with:

39/13= 3 headphones

13/13 = 1 music players
