Question

для шитья головного убора нужна заготовка прямоугольной формы длиной 55 см, шириной 30 см. сколько ткани потребуется для изготовления 30 таких головных уборов,если ее ширина 90 см?

Answer 1

90/30=3 заготовки помещается по ширине

30/3=10 заготовок нужно взять по длине

55*10=550см=5м 50см ткани потребуется для изготовления 30 таких головных уборов

Answer 2

90/30=3 убора в ширину

30/3=10 уборов в длинну

55*10=550см

550см=5м 50 см потребуется

 

 

 

 

 

 

Answer 3

Calculating Fabric Needed for Making Headgear

To calculate the amount of fabric needed for making 30 headgears with a width of 90 cm, we can use the given dimensions of the headgear template and the number of headgears required.

Given: - Length of the fabric needed for one headgear = 55 cm - Width of the fabric needed for one headgear = 30 cm - Width of the fabric available = 90 cm - Number of headgears required = 30

Calculation

To find the total fabric needed, we can use the following steps:

1. Calculate the fabric needed for one headgear: - The fabric needed for one headgear = Length * Width - The fabric needed for one headgear = 55 cm * 30 cm

2. Calculate the total fabric needed for 30 headgears: - Total fabric needed = Fabric needed for one headgear * Number of headgears - Total fabric needed = (55 cm * 30 cm) * 30

Result

The total amount of fabric needed for making 30 headgears with the given dimensions is 49500 square centimeters.

This calculation is based on the provided dimensions and quantity of headgears required.
