Answer:

799/5

Step-by-step explanation:

143+34(3)/5+(13)(3)4/+(11)(3/)5

=143+9/45+(13)(3)/4+(11)(3)/5

=143+9/20+(13)(3)/4+(11)(3)/5

=2869/20+(13)(3)/4+(11)(3)/5

=2869/20+394+(11)(3)/5

=766/5+(11)(3)5

=766/5+33/5

=799/5

Gina made 9350ml chicken noodle soup she packed 1.8l of soup in her kids lunches she froze the rest of the soup how many ml of s

Andre45 [30]

Answer:

7550 ml of soup Gina have left to freeze.

Step-by-step explanation:

Given:

Gina made 9350ml chicken noodle soup, she packed 1.8l of soup in her kids lunches.

She froze the rest of the soup.

Now, to find the ml of soup Gina have left to freeze.

The total quantity of soup Gina made = 9350 ml.

Quantity she packed for lunches = 1.8 l.

Now, we convert l into ml by using conversion factor:

1 l = 1000 ml.

1.8 l = 1.8 × 1000 ml.

1.8 l = 1800 ml.

Thus, the quantity she packed for lunches = 1800 ml.

Now, to get the ml of soup Gina have left to freeze we subtract the quantity she packed for lunches from the total quantity of soup she made:

$9350\ ml-1800\ ml\\\\=7550\ ml.$

Therefore, 7550 ml of soup Gina have left to freeze.

Compute the greatest root of x^4-x^3-19x^2+4x+60=0. Express your answer in simplified radical form.

erik [133]

Answer:

your answer can be either

Step-by-step explanation:

x = 5

x = 3

x= 0.0000 - 2.0000 i

x= 0.0000 + 2.0000 i

Step by step solution :

Step 1 :

Equation at the end of step 1 :

((((x4)-(8•(x3)))+19x2)-32x)+60 = 0

Step 2 :

Equation at the end of step 2 :

((((x4) - 23x3) + 19x2) - 32x) + 60 = 0

Step 3 :

Polynomial Roots Calculator :

3.1 Find roots (zeroes) of : F(x) = x4-8x3+19x2-32x+60

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 1 and the Trailing Constant is 60.

The factor(s) are:

of the Leading Coefficient : 1

of the Trailing Constant : 1 ,2 ,3 ,4 ,5 ,6 ,10 ,12 ,15 ,20 , etc
