Please help me! Please! I am so lost! Pythagorean Theorem!

Mathematics
1 answer:
Ket [755]2 years ago
4 0

Answer:

Part A- yes, because all 3 sides are Equal (each side is 5)

Part B- yes, each rectangle has the dimensions 12*5

Part C- yes- since the sides are 5 and 12 you can determine that the diagonal is 13, using they Pythagorean theorem a^{2} +b^{2} =c^{2}

5^{2} +12^{2} =13^{2} \\25+144=169- true statement, so the lateral sides are rectangles, because the corners are 90

Part D-  4\sqrt{2} (it is a 45-45-90 triangle- so the hypotenuse is the side length times \sqrt{2}

Part E- the diagonal face as the largest area- dimensions are 4\sqrt{2} * 12\\

the area would be 48\sqrt{2}

Old faithful in Yellowstone National Park shoots water 60 feet into the air that casts a shadow of 42 feet. What is the height o
Serhud [2]

Answer:

The height of near by tree will be 90 feet.

Step-by-step explanation:

Considering the water triangle as shown in figure a.

As the old faithful shoots water 60 feet into the air that casts a shadow of 42 feet.

Considering the tree triangle as shown in figure a. The tree triangle has a shadow 63 feet long.

Let x be the height of near by tree that cost a shadow 63 feet long.

Assuming that the triangles are similar

So,

the ratios of similar triangles will be related as:

\frac{63}{42}=\frac{x}{60}

\mathrm{Switch\:sides}

\frac{x}{60}=\frac{63}{42}

{x}=60.\frac{63}{42}

x=90 feet

Therefore, the height of near by tree will be 90 feet.

Keywords: ratio, similar triangle

Guys Please help me with this question urgent!!
Viefleur [7K]

Answer:

9

Step-by-step explanation:

1.)Find the amount of women within the 120 people in the meeting. So 3/10*120 , you get 36.

2.)Add 24 to 120 to get the new amount of people in the room. So 144.

3.)Using the new ratio 11:5 , find the amount of total women out of 144 people . So 5/16*144 , you get 45.

4.)Now minus the 2 amounts of initial women from the amount of total new women , to get the difference to find out how many women are there in the 24 people. So 45-36 , you get 9

Eggs are sold in boxes. A small box holds 6 eggs.A large box holds 12 eggs.Hina buys x small boxes of eggs.Hina also buys 4 less
yuradex [85]

Answer:

a) 12x - 48 or 6(2x - 8)

b) 18x - 48 or 6(3x - 8)

Step-by-step explanation:

A small box holds 6 eggs

A large box holds 12 eggs.

Hina buys x small box of eggs

Hina also buys (x-4) large box of eggs

a) Total number of eggs in the large box by Hina = (x-4)12

= 12x - 48

= 6(2x - 8)

b) Total number of eggs bought by Hina = (x) 6 + (x-4)12

= 6x + 12x - 48

= 18x - 48

= 6(3x - 8)
