Answer:

y ≤  \frac{2x}{ 3} + \frac{1}{ 5}.

Step-by-step explanation:

Given : Graph .

To find : Which linear inequality is represented by the graph.

Solution : We have given graph with shaded down and solid line

It has solid line it mean inequality has equal to sign.

It is shaded down it mean inequality  y has less than or equal to sign.

Slope = \frac{y_{2}-y_{1} }{x_{2}- x_{1}}.

Slope =  \frac{2.2- 0.2 }{ 3- 0}.

Slope =  \frac{2}{ 3}.

Y intercept = 0.2 =  \frac{2}{ 10}.

y intercept =  \frac{1}{ 5}.

Equation of line y = mx + b

Where m  = slope , b = y intercept .

Plug the values of slope and y intercept .

y ≤  \frac{2}{ 3} + \frac{1}{ 5}.

Therefore, y ≤  \frac{2x}{ 3} + \frac{1}{ 5}.

200g of gold is £4000. How much would 550g cost
Ne4ueva [31]

Answer:

£11,000.

Step-by-step explanation:

First, lets figure out how much 1g of gold costs by doing simple division:

£4000 / 200g = £20

1g = £20

Now we can multiply the cost of 1g of gold by 550g

£20 * 550g = £11,000

550g of gold would cost £11,000.

A child’s building set contains a brick with dimensions 63 x 31 x 18mm . Assume this brick is a replica of a real brick that has
TEA [102]

The surface area and volume of the real brick will be 983.2 cm²and 1738.11 cm³ respectively.

<h3>What is volume?</h3>

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.

The scale factor is ;

r = 630 cm /23

r = 27

L = 23 cm

b = 310 / 27 = 11.48 cm

h = 180/27 = 6.6 cm

The surface area of the brick;

A = 2(lb+bh+hl)

A = 2( 23 ×11.48+11.48×6.6+6.6×23)

A= 983.2 cm²

The volume of the brick is;

V= lbh

V=23 × 11.45 ×6.6

V=1738.11 cm³

Hence the surface area and volume of the real brick will be 983.2 cm² and 1738.11 cm³ respectively.
