Chocos is a dish made from wheat, sugar, and cocoa. Bertha is making a large pot of chocos for a party. Wheat(w) cost $5 per pound, sugar(s) costs $3 per pound, and cocoa(c) costs $4 per pound. She spends $48 on 12 pounds of food. She buys twice as much cocoa as sugar.

Answers

The question is incomplete, complete question is;

Chocos is a dish made from wheat, suguar, and cocoa. Bertha is making a large pot of chocos for a party. Wheat (w) costs $5 per pound, sugar (s) costs $3 per pound, and cocoa (c) costs $4 per pound. She spends $48 on 12 pounds of food. She buys twice as much cocoa as sugar. How much wheat, sugar, and cocoa will she use (in pounds) in her dish?

Answer:

She uses 3 pounds of wheat, 3 pounds of sugar and 6 pounds of cocoa in her dish.

Step-by-step explanation:

Given,

Total amount of spent money = $ 48

Total quantity of ingredients = 12 pounds

Let the quantity of wheat, sugar and cocoa she buys be x, y z pounds respectively.

$\therefore x+y+z=12\ equation 1\nand\ 5x+3y+4z=48\ equation2$

And according to question, quantity of cocoa is 2 times of sugar.

$\therefore z=2y$

Now substituting the value of z in equation 1and 2, we get;

$x+y+2y=12\nx+3y=12\ equation3$

$5x+3y+4*2y=48\n5x+3y+8y=48\n5x+11y=48\ equation\ 4$

Now multiply equation 3 by 5 and then subtract equation 4 from it.

$5(x+3y)=5*12\n(5x+15y=60)-(5x+11y=48)\n4y=12\ny=(12)/(4)=3$

$\therefore z=2y=2*3=6$

And substituting the value of y in equation 3, we get;

$x+3y=12\nx+3*3=12\nx+9=12\nx=12-9=3$

Thus the amount she uses is 3 pounds of wheat, 3 pounds of sugar and 6 pounds of cocoa in her dish.

This is because You have to divide the class into 4 parts ad you know each part has 5 people in it.

The quotient of (x4 – 3x2 + 4x – 3) and a polynomial is (x2 + x – 3). What is the polynomial?x4 – 2x2 + 5x – 6
x2 – x + 1
x6 + x5 – 6x4 + x3 + 10x2 – 15x + 9
x4 – 4x2 + 3x

Answers

Answer:

$x^2-x+1$

Step-by-step explanation:

We are given that

Dividend= $x^4-3x^2+4x-3$

Quotient= $x^2+x-3$

We have to find the divisor.

Let the polynomial = $p(x)$

$(x^4-3x^2+4x-3)/(p(x))=x^2+x-3$

$p(x)=(x^4-3x^2+4x-3)/(x^2+x-3)$

Hence, the polynomial $=p(x)=x^2-x+1$

Answer: $x^2-x+1$

The right answer for the question that is being asked and shown above is that: "x2 – x + 1."The quotient of (x4 – 3x2 + 4x – 3) and a polynomial is (x2 + x – 3). The polynomial is this one: x2 – x + 1
