8 0

If you want to share 747 pounds between Tom and Ben in ratio 2:7, then you should divide 747 by 2+7=9 in order to determine how many pounds will one part of 9 parts.

747:9=83.

Then Tom should get 2 such parts, that is 83·2=166 pounds and Ben should get 7 such parts, that is 83·7=581 pounds.

Answer: you should give 166 pounds to Tom and 581 pounds to Ben.

According to the Rational Root Theorem, what are all the potential rational roots of f(x) = 15x11 – 6x8 + x3 – 4x + 3?

scoundrel [369]

we have

$f(x) = 15x^{11} -6x^{8} + x^{3} - 4x + 3$

we know that

<u>The Rational Root Theorem</u> states that when a root 'x' is written as a fraction in lowest terms

$x=\frac{p}{q}$

p is an integer factor of the constant term, and q is an integer factor of the coefficient of the first monomial.

in this problem

the constant term is equal to $3$

and the first monomial is equal to $15x^{11}$ -----> coefficient is $15$

possible values of p are $1, and\ 3$

possible values of q are $1, 3, 5, and\ 15$

therefore

<u>the answer is</u>

The all potential rational roots of f(x) are

(+/-) $\frac{1}{15}$ ,(+/-) $\frac{1}{5}$ ,(+/-) $\frac{1}{3}$ ,(+/-) $\frac{3}{5}$ ,(+/-) $1$ ,(+/-) $3$

How many liters of wine can be held in a wine barrel whose capacity is 28.0 gal? 1 gal = 4 qt = 3.7854 l?

wel

Answer:

105.9912 liters of wine can be held in a wine barrel whose capacity is 28.0 gal.

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

Let x be the liters of wine can be held in a wine barrel whose capacity is 28.0 gal.

Given that:

1 gal = 3.7854 l

then

by definition of proportions;

$\frac{1}{3.7854} =\frac{28}{x}$

By cross multiply we get;

$x = 28 \times 3.7854 = 105.9912$ liters

Therefore, 105.9912 liters of wine can be held in a wine barrel whose capacity is 28.0 gal.
