8. Mohan wants to buy a trapezium shaped field.
mojhsa [17]

Answer:

<em>The length of the side along the river is 140 m</em>

Step-by-step explanation:

<u>Equations</u>

To solve the problem, we need to recall the area of a trapezium is:

\displaystyle A=\frac{b1+b2}{2}.h

Where b1 and b2 are the lengths of the parallel sides and h is the height of the trapezium.

The field to be bought by Mohan has a trapezium shape with a side along the road of side x and a side along the river of side 2x, as stated in the problem.

Knowing the height is h=100 m, and the area is 10500 m2:

\displaystyle \frac{x+2x}{2}\cdot 100=10500

Simplifying:

\displaystyle (3x)\cdot 50=10500

150x=10500

Dividing by 150:

x = 10500 / 150 = 70

x = 70 m

2x = 140 m

The length of the side along the river is 140 m

In the space below, provide the larger of the two positive integers that add to 10 and have the largest possible product.
aleksklad [387]

Answer:

  5

Step-by-step explanation:

The integers 5 and 5 sum to 10 and have the largest possible product.

___

The two numbers will be x and (10-x). Their product is x(10-x), which describes a downward-opening parabola with zeros at x=0 and x=10. The maximum (vertex) of that parabola is halfway between the zeros, at x=5. Both integers have the same value: 5. Their product is 25.

If there is a requirement the integers be distinct, then 6 and 4 are the integers of choice. Their product is 24.
