Answer:

Step-by-step explanation:

If we assume there is such a proportion, then we have the proportion:

m(x) = kx, where m is amount the person eats, k is coefficient of proportion, x is age of the person

For 5 year old we have:

m(5) = 5k

For 20 year old:

m(20) = 20k

For 60 year old:

m(60) = 60k

In reality this proportion doesn't make sense as 60 year old normally eats less than 20 year old.

What are the solutions of 2x^2+3x-7=x^2+5x+39

sveticcg [70]

Answer:

${x}^{2} - 2x - 46$

Step-by-step explanation:

${2x}^{2} + 3x - 7 = {x}^{2} + 5x + 39$

Collect like terms

${2x }^{2} - {x}^{2} + 3x - 5x - 7 - 39$

${ x}^{2} - 2x - 46$

What is the expression in radical form? (4x3y2)310

sertanlavr [38]

Given:

Consider the given expression is

$(4x^3y^2)^{\frac{3}{10}}$

To find:

The radical form of given expression.

Solution:

We have,

$(4x^3y^2)^{\frac{3}{10}}=(2^2)^{\frac{3}{10}}(x^3)^{\frac{3}{10}}(y^2)^{\frac{3}{10}}$

$(4x^3y^2)^{\frac{3}{10}}=(2)^{\frac{6}{10}}(x)^{\frac{9}{10}}(y)^{\frac{6}{10}}$

$(4x^3y^2)^{\frac{3}{10}}=(2)^{\frac{3}{5}}(x)^{\frac{9}{10}}(y)^{\frac{3}{5}}$

$(4x^3y^2)^{\frac{3}{10}}=\sqrt[5]{2^3}\sqrt[10]{x^9}\sqrt[5]{y^3}$ $[\because x^{\frac{1}{n}}=\sqrt[n]{x}]$

$(4x^3y^2)^{\frac{3}{10}}=\sqrt[5]{8y^3}\sqrt[10]{x^9}$ $[\because x^{\frac{1}{n}}=\sqrt[n]{x}]$

Therefore, the required radical form is $\sqrt[5]{8y^3}\sqrt[10]{x^9}$ .

Mr. Parker has 982 pounds of grain. He feeds 240 pounds ro his pigs and 460 to his cows. How much grain does he have left

denpristay [2]

Starting amount: 982 pounds of grain

Since Mr. Parker fed 240 pounds of grain to his pigs, subtract 240 pounds from 982 pounds of grain.

982 - 240 = 742

After feeding pigs: 742 pounds of grain

Mr. Parker fed another 460 pounds of grain to his cows from his 742 pounds, so subtract 460 pounds from 742 pounds.

742 - 460 = 282

After feeding pigs and cows: 282 pounds of grain

Mr. Parker has 282 pounds of grain left.
