Chevy has some yarn that he wants to use to make hats and scarves. each hat uses 0.20.20, point, 2 kilograms of yarn and each scarf uses 0.10.10, point, 1 kilograms of yarn. chevy wants to use 222 kilograms of yarn to make a total of 151515 items. let hhh be the number of hats chevy makes and sss be the number of scarves he makes. which system of equations represents this situation? choose 1

The system of equation that represent this situations are;

Also 5 hats and 10 scarves can be prepared from 2 kg of yarn.

Step-by-step explanation:

Let number of hat Chevy makes be h.

Also Let number of scarves Chevy makes be s.

Given:

Total Amount of yarns = 2 kg

Total number of items = 15

Since Items need to make are hat and scarves.

Hence the equation can be represented as;

Again Given:

Each hat uses 0.2 kilograms of yarn.

each scarf uses 0.1 kilograms of yarn.

Hence the equation can be represented as;

Hence the system of equation that represent this situations are;

Now Solving these to find number of hats and number of scarves.

Multiplying equation 2 with 10 we get;

Now Subtracting equation 1 from equation 3 we get;

Now Substituting the value of h in equation 1 we get;

Hence 5 hats and 10 scarves can be prepared from 2 kg of yarn.

answer: can you me with homework?

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
