Make is a proportion
6/18=28/x
Cross multiply
18•28=6•x
504=6x
x=84
Answer:
Rs.64
Step-by-step explanation:
<u>Amount of oranges:</u>
<u>Oranges sold:</u>
<u>Money made:</u>
<u>Selling price of 150 kg:</u>
<u>Cost price:</u>
- x+10% = 70.4
- x*1.1= 70.4
- x= 70.4/1.1
- x= Rs.64
- Cost price of oranges= Rs. 64
The answers are as follows:
1. Triangles are often used to build different types of support structures because of its beneficial properties. Triangles is rigid in shape and it has strength. When force is applied to the side of a triangle, it can not shift into another shape, this is because its sides and angles are fixed.
2. The properties of triangle that make it a desirable geometric shape for building support structures is its fixed sides, fixed angles, rigidity and strength. Triangles are the strongest shapes and they are stable. Thus, triangle can be easily fix together to provide strength and stability over a wide area.
3. There are different types of triangles, these include: equilateral triangle, scalene, isosceles, right triangle, obtuse and acute. Of all these triangles, the best triangle is equilateral triangle.
4. Triangle is preferred over other types of polygon because, it is the strongest. The other polygons can be bent into different other forms that are not regular polygon, but a triangle always retains its shape and can not be deformed.
I divided 339 by 6 and got 56.5. That quotient rounded to the nearest whole number is 57. I hope I helped you.
