To estimate the height of a totem pole, Jorge uses a small square of plastic. He holds the square up to his eyes and walks backw

ard from the pole. He stops when the bottom of the pole lines up with the bottom edge of the square and the top of the pole lines up with the top edge of the square. Jorge's eye level is about 2 m from the ground. He is about 3 m from the pole. Which of the following is the best estimate of the height of the totem pole?

The height of the pole is 6.50 meters

<h3>How to calculate the height?</h3>

To calculate the height of the pole, we will use of the following equivalent ratios.

By Pythagoras theorem, we have:

x ^2 = 2^2 + 3^2\\\\x ^2 = 4 + 9\\\\x = \sqrt{13}

So, we have:

h = \dfrac{\sqrt{13}^2 }{2} \\\\h = \dfrac{13}{2}\\\\h = 6.5

Hence, the height of the pole is 6.50 meters

Step-by-step explanation:

14) percentage of increase

% of increase = (new - original)/original × 100

= (40 - 35)/35 × 100

= 5/35 × 100

= 14.285% = 14% increase

15) percentage of decrease

% of decrease = (original - new)/original × 100

= (16 - 10)/16 × 100

= 6/16 × 100

= 37.5% = 38% decrease

16) percentage of increase

% of increase = (new - original)/original × 100

= (73 - 27)/27 × 100

= 46/27 × 100

= 170.37% = 170% increase

17) percentage of decrease

% of decrease = (original - new)/original × 100

= (92 - 21)/21 × 100

= 71/21 × 100

= 338.10% = 338% decrease

18) percentage of decrease

% of decrease = (original - new)/original × 100

= (21.2 - 10.8)/21.2 × 100

= 10.4/21.2 × 100

= 49.06% = 49% decrease

19) percentage of increase

% of increase = (new - original)/original × 100

= (25 - 11)/11 × 100

= 14/11 × 100

= 127.27% = 127% increase

20) percentage of increase

% of increase = (new - original)/original × 100

(76 - 68)/68 × 100

8/68 × 100 = 11.77% = 12%

21) percentage of increase

% of increase = (new - original)/original × 100

= (40 - 21)/21 × 100

= 19/21 × 100

= 90.47% =90%

22) New car = AED 45,500

Used car = x

New car = (25% of x) + x

45,500 = (25x/100) + x

45,500 = (25x + 100x)/100

45,500 = 125x/100

45,500 × 100 = 125x

4,550,000 = 125x

x = 4,550,000/125 = 36,000

x = AED 36,000

PLEASE HELP- I NEED CORRECT ANSWER!!
Sergio [31]

Answer:

y > 4x + 2

Step-by-step explanation:

Y is above the line so the value has to be greater than the line (or equal to, possibly). So it represents > or ≥

A dotted/dashed line is non-inclusive, so it represents < or >.

Since it is both above the line AND non-inclusive, we would use this sign:

>

and this equation :)

y > 4x + 2
