When solving a quadratic equation, what is the difference between a root and a solution?
A. The solution is expressed as x=a where a is a number. The root is expressed as an ordered pair.
B. For a quadratic equation, the root is the same as the solution.
C.The root is expressed as x=a where a is a number. The solution is expressed as an ordered pair.
D. The root is where the graph of the quadratic equation crosses the x -axis. The solution of the quadratic equation is where the graph crosses the y-axis.
Answers
Answer:
B: For quadratic equations, the root is the same as the solution.
Step-by-step explanation:
In quadratic equations of the form ax² + bx + c = 0, the roots are usually gotten from the formula ;
x = [-b ± √(b² - 4ac)]/(2a)
Now, the roots gotten are also termed as solutions because every value of x which is a root gives a solution of 0 when plugged into the quadratic equation.
Basically, in quadratic equations, the roots are solutions to the equation.

Answer:
26 green marbles
Step-by-step explanation:
There are 100 marbles in the jar.
100 marbles are 100%
26% of these marbles are green.
Just as there are 100 marbles, we need to find how many marbles are green.
Let us do it like that: let a be the actual number of green marbles.
Marbles Percent
100 100%
a 26%
Let's find the ratio between 100% and 26% by doing 100/26 = 3.846153
We need to multiply 26 by 3.846153 in order to get to 100, right?
So same, I'll need to multiply a times 3.846153 in order to get 100.
3.846153 a = 100
divide both sides by 3.846153
a = 26 marbles
Therefore there are 26 green marbles.

A rotating sprinkler head sprays water as far as 20 feet. The head is set to cover a central angle of 80 degrees. What area of grass will be watered?
A. 200/9 pi ft^2
B. 800/9 pi ft^2
C. 80/9 pi ft^2
D. 760/9 pi ft^2
Answers
Using the area of a circle, it is found that the area of the grass that will be watered is given by:
B. 800/9 pi ft^2
What is the area of a circle?The area of a circle of radius r is given by:
[tex]A = \pi r^2[/tex].
In this problem, a rotating sprinkler head sprays water as far as 20 feet, hence the radius is of r = 20 ft.
It covers a central angle of 80º, while an entire circle has 360º, hence the area of grass that will be watered corresponds to 80/360 = 2/9 of the area of the circle.
Hence the watered area in ft² is given by:
[tex]A = \frac{2}{9}\pi (20)^2 = \frac{800\pi}{9}[/tex]
Which means that option B is correct.

Airlines have increasingly outsourced the maintenance of their planes to other companies. A concern voiced by critics is that the maintenance may be less carefully done so that outsourcing creates a safety hazard. In addition, flight delays are often due to maintenance problems, so one might look at government data on percent of major maintenance outsourced and percent of flight delays blamed on the airline to determine if these concerns are justified. This was done, and data from 2005 and 2006 appeared to justify the concerns of the critics. Do more recent data still support the concerns of the critics? Here are data from 2014:
Alaska 51.051.0 10.3510.35 Jet Blue 68.468.4 19.9319.93

Flora's Flower Shop is gearing up for Valentine's Day, which is typically their busiest time of the year. Flora was able to secure 9,000 red roses for the holiday this year. Flora sells red roses for $8 per stem, and bouquets of 12 red roses for $75. The cost per stem for Flora is $3. Typically half of all flowers are sold as individual stems and half as bouquets, however on Valentine's Day the majority of flowers are sold as part of bouquets. Last year Flora made $35,000 over the Valentine's Day holiday, and hopes to make the same profit this year. What is the maximum proportion of flower sales that can come from bouquets in order for Flora to earn a profit of $35,000. 42% O 50% 63% 81%
Answers
The maximum proportion of flower sales that can come from bouquets in order for Flora to earn a profit of $35,000 is A. 42%.
What is proportion?The proportion shows the ratios of two or more variables.
While the maximum proportion show the highest ratio or percentage of a variable required to equate an expression.
Data and Calculations:Number of red roses procured for sale = 9,000
Selling price per stem = $8
Selling price per bouquet (12 stems) = $75
Cost per stem = $3
Last year's Valentine Day profit = $35,000
Stem Boutique
Selling price $8 $75
Cost per stem 3 36 ($3 x 12)
Contribution margin per unit $5 $39 ($75 - $36)
Contribution margin per stem $5 $3.25 ($39/12)
Weighted contribution margin $22,500 $14,625 ($3.25 x 4,500)
Proportion 42% ($14,625/$35,000 x 100)
Thus, the maximum proportion of flower sales that can come from bouquets in order for Flora to earn a profit of $35,000 is A. 42%.

Step-by-step explanation:
If Sami starts with $500 and earns 4% and she doesnt take away any money, the equation would be:
y=500(1.04)^x
y being dollars and x in years
if we replace x with 4, the answers come out to be 584.92928
Answer:
Step-by-step explanation:
First, we express the annual interest rate r, in decimal form. Since it is 4%, the interest rate is
r=4%=4100=0.04.
The principal P=500, so the future value is
A=P(1+rt)=500(1+(0.04)(4))=$580.

40/45 = 0.888888888 Rs/banana
If he is losing 20% on this deal,
This means that
0.8888888/x = 80/100
88.88888 = 80x
Divide both sides by 80
x = 1.1111111111
So, if he wants to make 0% profit, he must sell the 45 bananas for 1.11111 Rs each.
If he wants to make 20% profit for 45 bananas,
1.111111 x 1.2 = 1.3333333
He will need to sell each banana for Rs 1.3333333.
So,
y = 1.333333x
And we are given
y = 24x
We can equal these equations to each other
1.333333333(45) = 24x
60 = 24x
x = 2.5
He will need to sell only 2.5 bananas.
