2 1/2 kg of Rice How many cup of rice of you have if 1 cup= 8oz

kramer

Answer:

About 11 cups of rice

Step-by-step explanation:

We have 2 1/2 kg of rice. Or we can say 2.5 kg of rice.

Since we want cups and cups is given with ounces (oz), we need to convert the kg amount to ounce amount, first.

We know:

1 kg = 35.274 oz

So, 2.5 kg is:

2.5 * 35.274 = 88.185 oz

Since 1 cup is 8 oz, 88.185 oz is how many cup??

That would be:

88.185/8 = 11.02 cups

Rounded, that is about 11 cups of rice

What is the equation in standard form of a parabola that models the values in the table

shusha [124]

Answer:

Y=4x^2-3x+5

Step-by-step explanation:

For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:

$Y=-4x^2+3x+5$ for (-1,12)

$Y=-4(-1)^2+3(-1)+5=-4(1)+-3+5=-4+-3+5=-2\\$

This does not give 12 as the answer and is not a solution.

$Y=-4x^2-3x+5$ for (-1,12)

$Y=-4(-1)^2-3(-1)+5=-4(1)+3+5=-4+3+5=4\\$

This does not give 12 as the answer and is not a solution.

$Y=3x^2-4x+5$ for (-1,12)

$Y=3(-1)^2-4(-1)+5=3(1)+4+5=3+4+5=12\\$

This does give 12 as the answer and is a possible solution.

We now try (2,15).

$Y=3(2)^2-4(2)+5=3(4)-8+5=12-8+5=9\\$

This does not give 15 as the answer and is not a possible solution.

$Y=4x^2-3x+5$ for (-1,12)

$Y=4(-1)^2-3(-1)+5=4(1)+3+5=4+3+5=12\\$

This does not give 12 as the answer and is not a solution.

We now try (2,15).

$Y=4(2)^2-3(2)+5=4(4)-6+5=16-6+5=15\\$

This does give 15 as the answer and is a solution.

This is the standard form of the equation.
