Hello there!

To find which tuna is a better deal, divide the cost by the number of ounces of tuna you are getting to get the cost per ounce.

$0.90/5 = $0.18 per ounce

$2.40/12 = $0.20 per ounce

Since the 5-ounce can of tuna has a cheaper unit rate price, meaning you are getting a better value, makes this the best option. I hope this was helpful and have a great day! :)

2 people have calculators, one person starts at 100 and subtracts 7 each time. Another starts at zero and adds 3 each time. If t

zaharov [31]

Answer:

Yes, after 10 key presses, both will arrive at the number 30.

Step-by-step explanation:

The difference between the numbers on the calculators is reduced by 10 with each key press. After 10 key presses, the initial difference of 100 will be zero. After 10 key presses of (-7), the calculator starting at 100 will be ...

100 +10(-7) = 30

After 10 key presses of (+3), the calculator starting at 0 will be ...

0 +10(+3) = 30

Both calculators will show 30 after 10 key presses.

Find the quotient of <br><br> -85^2-27n+76 / -17n-19

bagirrra123 [75]

<u><em>Answer:</em></u>
5n-4

<u><em>Explanation:</em></u>
<u>The given expression is:</u>
$\frac{-85n^2-27n+76}{-17n-19}$

<u>1- Take the negative as a common factor from both the numerator and the denominator. This will give us:</u>
$\frac{-(85n^2+27n-76)}{-(17n+19)}$

<u>2- Cancel out the negative sign (common factor) from the numerator and denominator. This will give us:</u>
$\frac{(85n^2+27n-76)}{(17n+19)}$

<u>3- Factor the numerator. This wil give:</u>
$\frac{(5n-4)(17n+19)}{(17n+19)}$

<u>4- Finally, cancel out the (17n+19) which common in both numerator and denominator. This will give us the final expression:</u>
5n-4

Hope this helps :)

Polynomial of degree 4 has 1 positive real root that is bouncer and 1 negative real root that is a bouncer. How many imaginary r

Rainbow [258]

Answer:

<h3>The given polynomial of degree 4 has atleast one imaginary root</h3>

Step-by-step explanation:

Given that " Polynomial of degree 4 has 1 positive real root that is bouncer and 1 negative real root that is a bouncer:

<h3>To find how many imaginary roots does the polynomial have :</h3>

Since the degree of given polynomial is 4
Therefore it must have four roots.
Already given that the given polynomial has 1 positive real root and 1 negative real root .
Every polynomial with degree greater than 1 has atleast one imaginary root.

<h3>Hence the given polynomial of degree 4 has atleast one imaginary root</h3><h3> </h3>

If the arc length of a sector in the unit circle is 4.2, what is the measure of the angle of the sector?

iren [92.7K]

Bear in mind the Unit Circle is called so, because its radius is exactly 1, thus just 1 unit, the Unit Circle

anyway $\bf \theta=\cfrac{180s}{\pi r}\qquad 
\begin{cases}
\theta=\textit{central angle in degrees}\\
r=radius\\
s=\textit{length of the arc}\\
----------\\
s=4.2\\
r=1
\end{cases}\implies \theta=\cfrac{180\cdot 4.2}{1\cdot \pi }$
