John and some friends went to a sushi restaurant and ordered some sushi. He bought 2 Ahi Tuna, 1 California Roll, and 1 Eel Rolls. His total was $26.20. Sally only ordered 3 California Rolls her total was $17.85. Elijah ordered 3 Ahi Tuna and 2 California Rolls and his total was $34.
What is John's Equation?
What is Sally's equation?
Answer:
Let "a" represent amount of ahi tuna, "c" represent California rolls, and "e" represent eel rolls.
John: 2a+c+e=26.20
Sally: 3c = 17.85

There are 72 seats on a train. 54 of the seats are empty. What percentage of the seats on the train are empty?
Answer:
Explanation:
A ratio is the fractional representation of two different numbers, defined by the order in which we want to describe them We want a ratio of (Occupied)/(Empty) seats, so we put the occupied seat value in the numerator and the empty seat value in the denominator.
Ratio = 17/11
The decimal form can be obtained by doing the division: 1.545 occupied seats per empty seat.

John travels at an average speed of 90 km/h for 2 hours 30 minutes. Find the distance travelled in
km.
traveledAnswer:
225 km
Step-by-step explanation:
We know that in 1 hour he will travel 90 km, so in 2 hours, he will travel double what he did in one, so multiply 90 by 2 and we get 180. If he travelled 90 km in 1 hour, then for half that time he traveled half the distance, so 90/2 is 45. Now add 180 and 45 and we get 225 km. Hope this helps!

find the square roots of 36 + 36sqrt3i
Answer:
[tex]3\sqrt{6}+3\sqrt{2}i[/tex] and [tex]-3\sqrt{6}-3\sqrt{2}i[/tex]
Step-by-step explanation:
For a complex number [tex]z=a+bi[/tex] in rectangular form, polar form is [tex]z=r[cos(\theta)+isin(\theta)][/tex] where [tex]r=\sqrt{a^2+b^2}[/tex] and [tex]\theta=tan^{-1}(\frac{b}{a})[/tex]:
[tex]r=\sqrt{a^2+b^2}\\\\r=\sqrt{(36)^2+(36\sqrt{3})^2}\\\\r=\sqrt{1296+3888}\\\\r=\sqrt{5184}\\\\r=72[/tex]
[tex]\theta=tan^{-1}(\frac{b}{a})\\ \\\theta=tan^{-1}(\frac{36\sqrt{3}}{36})\\ \\\theta=tan^{-1}(\sqrt{3})\\\\\theta=\frac{\pi}{3}[/tex]
Thus, our complex number in polar form is [tex]z=72[cos(\frac{\pi}{3})+isin(\frac{\pi}{3})][/tex]. This will help us determine the square roots of the complex number using the formula [tex]\sqrt[n]{r}\biggr[cis\bigr({\frac{\theta+2\pi k}{n})\biggr][/tex] for [tex]k=0,1,2,\: ... \:,n-1[/tex]. Note that [tex]cis(\theta)=cos(\theta)+isin(\theta)[/tex]:
1st square root for k = 2-1 = 1
[tex]\sqrt[n]{r}\biggr[cis\bigr({\frac{\theta+2\pi k}{n})\biggr][/tex]
[tex]\sqrt[2]{72}\biggr[cis\bigr({\frac{\frac{\pi}{3}+2\pi(1)}{2})\biggr][/tex]
[tex]6\sqrt{2}\biggr[cis\bigr({\frac{\frac{\pi}{3}+2\pi}{2})\biggr][/tex]
[tex]6\sqrt{2}\biggr[cis\bigr(\frac{\pi}{6}+\pi)\biggr][/tex]
[tex]6\sqrt{2}\biggr[cis\bigr(\frac{7\pi}{6})\biggr][/tex]
[tex]6\sqrt{2}\biggr[cos(\frac{7\pi}{6})+isin(\frac{7\pi}{6})\biggr]\\ \\6\sqrt{2}(-\frac{\sqrt{3}}{2}-\frac{1}{2}i)\\\\-3\sqrt{6}-3\sqrt{2}i[/tex]
2nd square root for k = 1-1 = 0
[tex]\sqrt[6]{72}\biggr[cis\bigr({\frac{\frac{\pi}{3}+2\pi(0)}{2}\bigr)\biggr][/tex]
[tex]6\sqrt{2}\biggr[cis(\frac{\pi}{6} )\biggr][/tex]
[tex]6\sqrt{2}[cos(\frac{\pi}{6})+isin(\frac{\pi}{6})]\\ \\6\sqrt{2}(\frac{\sqrt{3}}{2}+\frac{1}{2})\\\\3\sqrt{6}+3\sqrt{2}i[/tex]
Therefore, the square roots of [tex]36+36\sqrt{3}i[/tex] are [tex]3\sqrt{6}+3\sqrt{2}i[/tex] and [tex]-3\sqrt{6}-3\sqrt{2}i[/tex].

Tell me if you don't understand!
The division of the expression when 40 divided by 28 is [tex]\dfrac{10}{7}[/tex] or 1.42857143.
A number that divides another number without leaving any remainder and the quotient is a whole number is called a factor.
The factors of 12 are = 1,2,3,4,6 and 12.
Here, when these factor will divide 12, there will no remainder, i.e. they will completely divide 12.
The division of the expression 40 divided by 28 is calculated as:
The factors of 40 are : 1,2,4,5,8,10,20 and 40
The factors of 28 are: 1,2,4,7,14 and 28.
This expression can be written as:
[tex]\dfrac{40}{28}=\dfrac{1\times2\times4\times5\times8\times10\times20\times40}{ 1\times 2\times 4\times 7\times 14\times 28}[/tex]
The numbers cancel out using the rule of divisibility, and the remaining fraction will be [tex]\dfrac{10}{7}[/tex] and in decimal form will be 1.42857143.
Thus, when 40 is divided by 28, the result is 1.42857143 or [tex]\dfrac{10}{7}[/tex] in fraction form.

The book value of a $3,500 computer after 2 years is $2380
How to calculate book value
The book value is gotten by subtracting the product of the initial value and MACRS rate from the initial value.
The book value after 2 years = 3500 - (32% of 3500)
The book value after 2 years = 3500 - (0.32 * 3500) = 2380

Explain why some systems of equations have no solutions, why some systems have one solution, and why some systems have infinite
solutions.
Answer:Some equations may not have solutions and some may have one or more than one is because of the variables or how they are written
Step-by-step explanation:not 100% sure this is the correct answer,I tried my best.
A system of equations consists on a group of equations that we must solve at the same time.
From this, the solutions of a system of equations appear as the intersections between the graphs of the equations that conform the system.
So for example, if a system has two parallel lines (two lines that never intersect) that system will have no solution.
If a system has two different and not parallel lines, these lines will intersect at some point, so this system will have one solution.
And finally, if the system has twice the same line, the graphs of the lines will intersect in infinite points, thus, this system has infinite solutions.

Frequency is b/2 pi.
Here b is 124 pi. so the frequency is
[tex] \frac{124\pi}{2\pi} = 52[/tex]
The frequency is 52
Answer: 62
Step-by-step explanation:
I got it correct with this answer
Write the absolute value equations in the form (x – b |=c (where b is a number and c
can be either a number or an expression) that has the following solution set.
all numbers such that x>-1.3
The absolute value equation is:
|x + 1.3| = x + 1.3
Working with absolute value equations:
The absolute value equation that we have is:
|x - b| = c
And we want that the solution set is all the numbers larger than -1.3
Now, remember that:
| something| ≥ 0.
So the absolute value is always equal or larger than zero.
So, for example, the equation:
|x| = x
Only is true if x ≥ 0, because if x is smaller than zero, for example x = -2, we would have:
|-2| = -2
2 = -2
Which is false.
Now we want to have solutions larger than -1.3 instead of larger than zero, so we can write:
|x + 1.3| = x + 1.3
The solution of this equation is the given set.
