Material for a dress costs £5.50 per metre.<br> find the cost of 10cm and 70cm

Zielflug [23.3K]

Answer:

<em>The cost of 10 cm and 70 cm are £0.55 and £3.85 respectively.</em>

Step-by-step explanation:

Material for a dress costs £5.50 per meter.

We know that, <u>1 meter = 100 cm</u>.

Suppose, the cost of 10 cm material is $x$ and the cost of 70 cm material is $y$

Now, <u>according to the ratio of "cost" to the "length of material"</u> , we will get.......

$\frac{x}{10} =\frac{5.50}{100}\\ \\ 100x=10*5.50=55\\ \\ x=\frac{55}{100}=0.55$

and

$\frac{y}{70} =\frac{5.50}{100}\\ \\ 100y=70*5.50=385\\ \\ x=\frac{385}{100}=3.85$

So, the cost of 10 cm material is £0.55 and the cost of 70 cm material is £3.85

Please Help 7th grade math

Allisa [31]

The signs of the numbers in the problem matter because if a number is negative in the equation than you're answer could be negative. ex. -3/9= -3 but if the negative sign wasn't there than the answer would be wrong bc the answer would be positive.

hope thats what you need hope it helps.
