Identify a pair of supplementary angles

Use the information about nutrition on page 173 to explain how linear equations can be used in nutrition. Explain how you could

alex41 [277]

Answer: By looking at several aspects of the Nutrition Information, such as the Serving Size, Total Calories and the Nutrition Terms, you can limit how much fat your body takes in. For instance, looking at the serving size is the first thing you should do. By looking at the serving size, you can determine how much calories, vitamins, cholesterol, etc you will take in. The next step is to check the total amount of calories the food/drink has. To truly limit your fat intake, you want to pay attention how much calories the food is and compare it to how much you ate/drank today. Lastly make sure you pay attention on how much cholesterol and saturated fat to minimize your fat intake.

A regular decagon has a radius of 14'. Determine the length of the apothem. Then determine the perimeter of the decagon

pav-90 [236]

Answer:

Part 1) The length of the apothem is 13.32'

Part 2) The perimeter of the decagon is 86.5'

Step-by-step explanation:

we know that

A regular decagon has 10 equal sides and 10 equal interior angles

A regular decagon can be divided into 10 congruent isosceles triangle

(they are isosceles since their two sides are the radii of the polygon and the unknown side is the side of the polygon)

The vertex angle of each isosceles triangle is equal to

$\frac{360^o}{10}=36^o$

To find out the side length of the decagon, we can use the law of cosines

so

$c^2=a^2+b^2-2(a)(b)cos(C)$

where

c is the length side of decagon

a and b are the radii

we have

$a=14'\\b=14'\\C=36^o$

substitute the values

$c^2=14^2+14^2-2(14)(14)cos(36^o)$

$c^2=392-(392)cos(36^o)$

$c=8.65'$

To fin out the perimeter of decagon multiply the length side by 10

so

$P=8.65(10)=86.5'$

To find out the apothem we can apply the Pythagorean Theorem in one isosceles triangle

see the attached figure to better understand the problem

$r^2=a^2+(c/2)^2$

substitute the given values

$14^2=a^2+(8.65/2)^2$

solve for a

$a^2=14^2-(8.65/2)^2$

$a=13.32'$

What is the value of h in the figure below? In this diagram, ABAD - ACBD.

andreev551 [17]

Answer:

h =12

Step-by-step explanation:

$In\: \triangle ABC, \: \angle ABC = 90\degree \: \&\:\\ BD\perp AC$

Therefore, by geometric mean property:

$BD = \sqrt {AD\times CD} \\h = \sqrt {(AC-CD) \times CD} \\h = \sqrt {(25-16) \times 16} \\h = \sqrt {9 \times 16} \\h = \sqrt {144} \\\huge \red {\boxed {h = 12}} \\$

The diagram shows a scale drawing of a playground the scale of the drawing is 1:500 work out the perimeter of the real playgroun

liraira [26]

Answer:

Check Explanation

Step-by-step explanation:

The complete question plus diagram is presented in the attached image to this solution.

From the attached image, the dimensions of the playground drawn will be a bit variable now as zooming and some editing might have tampered with the original intended dimensions to be measured.

But still, let us assume that on measuring the rectangular playground shown, we obtain approximately that the length is 4.5 cm and the breadth is 2 cm.

The scale to convert to real life is 1;500 indicating that

1 cm on the drawing = 500 cm lenght units of the real playground.

So,

4.5 cm on the drawing = 4.5 × 500 = 2250 cm of the playground

2 cm on the drawing = 2 × 500 = 1000 cm of the playground.

Hence, the real life dimensions of the playground is 2250 cm by 1000 cm.

In meters, that is 2.25 m by 1 m

The perimeter of a rectangular figure is given as

Perimeter = 2(Length + Breadth)

= 2(2.25 + 1)

= 6.5 m

Hope this Helps!!!
