The roof of a new sports arena rests on round concrete pillars. The maximum load a cylindrical column of a circular cross sectio

KATRIN_1 [288]

Answer: There are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Step-by-step explanation:

Since we have given that

Height of columns of arena = 9 m

Diameter = 1 m

Load = 14 metric tons

Since Load is directly varies as the fourth power of the diameter 'd', and inversely as the square of the height.

so, Mathematically, it is expressed as

$L=\dfrac{kd^4}{h^2}\\\\14=\dfrac{1.k}{9^2}\\\\14\times 81=k\\\\k=1134$

If the height of columns = 8 m

Diameter = $\dfrac{2}{3}\ m$

So, Load would be

$L=\dfrac{1134\times (\dfrac{2}{3})^4}{8^2}\\\\L=3.5\ tons$

Hence, there are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Pls help with this question.

avanturin [10]

Answer:

24 ml oil

60 g onions

360 g potatoes

400 ml milk

Step-by-step explanation:

The recipe makes 16 portions and you only need 4 portions. Since 16 is 4 times bigger than what you need, just divide everything you've been given by 4.

<em>*you can choose to convert into the correct units of measurement before or after dividing. I converted after dividing. Either way works fine though.</em>

1) 96/4 = 24 ml

2) 240/4 = 60 g

3) 1.44/4 = 0.36 kg

They want it in grams, so times it by 1,000 to convert. this gives you 360 g.

4) 1.6/4 = 0.4 l

They want it in ml, so times it by 1,000 to convert. this gives you 400 ml.

Hope this helped : )

A rectangular rug is 24 feet long and 10 feet wide. A rhombus design is formed inside the rug by joining the midpoints of each s

Mice21 [21]

In all geometry problems, drawing a diagram is most helpful.

The half-side lengths are 5 feet and 12 feet.

By the Pythagorean Theorem, the hypothenuse, or side length of the rhombus is therefore

sqrt(5^2+12^2)=sqrt(169)=sqrt(13^2)

= 13 feet.

See diagram below.
