An alloy is composed of nickel, zinc, and copper in a ration of 7:2:9. How many kilograms of each metal are needed to make 3.6kg
motikmotik
Well, the short answer is, we divide that 3.6 by (7+2+9) and then we give as many pieces at the ratio to each, so let's do so,

\bf \stackrel{nickel}{7}~~:~~\stackrel{zinc}{2}~~:~~\stackrel{copper}{9}
\\\\\\
\stackrel{nickel}{7\cdot \frac{3.6}{7+2+9}}~~:~~\stackrel{zinc}{2\cdot \frac{3.6}{7+2+9}}~~:~~\stackrel{copper}{9\cdot \frac{3.6}{7+2+9}}
\\\\\\
\stackrel{nickel}{7\cdot 0.2}~~:~~\stackrel{zinc}{2\cdot 0.2}~~:~~\stackrel{copper}{9\cdot 0.2}
\\\\\\
\stackrel{nickel}{1.4}~~:~~\stackrel{zinc}{0.4}~~:~~\stackrel{copper}{1.8}

A path 5m wide is to be built along the border and inside a square garden of side 90m. Find the cost of cementing the path at th
gizmo_the_mogwai [7]

Answer:

Total cost of cementing the path = Rs. 17,000.

Step-by-step explanation:

Let the square garden be ABCD

Let the region inside the garden (ABCD) be WXYZ.

<u>Given the following data;</u>

Length of sides of ABCD = 90m

Width of path = 5m

Cost = Rs. 10 per m²

Area of ABCD = 90 * 90

Area of ABCD = 8100m²

<em>To find the area of WXYZ;</em>

WX = WZ = 90 - (5 + 5)

WX = WZ = 90 - 10

WX = WZ = 80m

Area of WXYZ = WX * WZ

Substituting into the equation, we have;

Area of WXYZ = 80 * 80

Area of WXYZ = 6400 m²

Area of path = Area of ABCD - Area of WXYZ

Area of path = 8100 - 6400

Area of path = 1700 m²

Total cost of cementing the path = Area of path * cost

Total cost of cementing the path = 1700 * 10

<em>Total cost of cementing the path = Rs. 17,000</em>

A ship sails from point (1, 2) to point (5, 5), as shown. If each unit represents one mile, how far has the ship sailed?
GrogVix [38]

Hello!

To find how far the ship has sailed, we need to use the distance formula. The distance formula is: d = \sqrt{(x_{2}-x_{1}) ^{2}+ (y_{2}-y_{1}) ^{2} }.

Before using the formula, we need to assign the given points to (x_{1}, y_{1}) and (x_{2},y_{2}). The point (1, 2) can be assigned to (x_{1}, y_{1}) and (5, 5) can be assigned to (x_{2},y_{2}).

With the assigned ordered pairs, we can substitute it into the formula.

d = \sqrt{(5-1) ^{2}+ (5-2) ^{2} }

d= \sqrt{(4) ^{2}+ (3) ^{2} }

d = \sqrt{16 + 9}

d = \sqrt{25} = 5

Given that each unit represents one mile, then therefore the ship has sailed 5 miles, which is choice A.
