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

a rectangular pool is 8 yards long 6 yards wide and 5 feet deep .convert the measurements of the length and width to feet​
ExtremeBDS [4]

Answer:

1 yard = 3 feet

Keeping this in mind, we need to multiply the yard lengths by 3 to convert the measurements to feet.

8 feet x 3 = 24 yards

6 feet x 3 = 18 yards

5 feet x 3 = 15 yards

So

8 ft = 24 yd

6 ft = 18 yd

5 ft = 15 yd

plz mark brainliest if this helped :)
