Answer:
The greatest number of arrangements she can make would be that she uses 4 groups of 5 daisies and 4 groups of 4 roses.
The greatest number of arrangements is 4, and each group has 5 daises and 4 roses.
What is the greatest common divisor?The biggest positive integer that divides both numbers and is a divisor of both is known as the greatest common divisor of two integers.
Given that, Amanda has 20 daises and 16 roses.
The number of arrangements that can be made using 20 daises and 16 roses is the greatest number that can divide both the numbers 20 and 16.
The greatest number that can divide both 20 and 16 is 4.
Hence, 4 groups of arrangements can be made.
The number of daises in a group is:
20/4
= 5
The number of roses in a group is:
16/4
= 4
Hence, the greatest number of arrangements is 4, and each group has 5 daises and 4 roses.

Step-by-step explanation:
The solution of this systems of equations is the intersection of both graphs
Let's kick start with a:
a)
[tex]y+12 = x^2+x \\ \\ x+3 = y[/tex]
From the first attached diagram by using graph:
the solution is the set {(-5, 8), (3, 0)}
b)
[tex]y-15=x^3+4x \\ \\ x-y =1[/tex]
Using the graph tool from the last diagram below;
the solution is the set⇒( there is no solution)
c)
[tex]y+5 =x^2-3x \\ \\ 2x+y =1[/tex]
From the second attached diagram by using graph:
the solution is the set {(-2, 5), (3, -5)}
d)
[tex]y-6=x^2-3x \\ \\ x+2y =2[/tex]
the solution is the set ⇒ there is no solution (shown in the last diagram below)
e)
[tex]y-17=x^2-9x \\ \\ -x+y =1[/tex]
the solution is the set {(2, 3), (8, 9)} as shown in the third diagram
f) Lastly:
[tex]y-15=-x^2+4x \\ \\ x+y =1[/tex]
Using the graph tool from the fourth diagram below;
the solution is the set {(-2, 3), (7, -6)}
The solution to the system of equations are the truth values of the system of equations
[tex]\mathbf{(a)\ y + 12 = x^2 + x,\ x + 3 = y}[/tex]
The graphs of the equations intersect at (-5,8) and (3,0).
So, the solution set is {(-5,8), (3,0)}
[tex]\mathbf{(b)\ y - 15 = x^3 + 4x,\ x - y = 1}[/tex]
The graphs of the equations do not intersect
So, the system has no solution
[tex]\mathbf{(c)\ y + 5 = x^2 - 3x,\ 2x + y = 1}[/tex]
The graphs of the equations intersect at (-2,5) and (3, -5).
So, the solution set is {(-2, 5), (3, -5)}
[tex]\mathbf{(d)\ y - 6 = x^2 - 3x,\ x + 2y = 2}[/tex]
The graphs of the equations do not intersect
So, the system has no solution
[tex]\mathbf{(e)\ y - 17 = x^2 - 9x,\ -x + y = 1}[/tex]
The graphs of the equations intersect at (2,3) and (8,9).
So, the solution set is {(2, 3), (8, 9)}
[tex]\mathbf{(f)\ y - 15 = -x^2 + 4x,\ x + y = 1}[/tex]
The graphs of the equations intersect at (-2,3) and (7,-6).
So, the solution set is {(-2, 3), (7, -6)}

The ratio of boys to girls in a group is 5:1. If there are 60 more boys than girls, work out how many people there are in total.
Answer:
The number of boys: a
The number of girls: b
=> a/b = 5
a - b = 60
=> (b + 60)/b = 5
=> b + 60 = 5b
=> 4b = 60 => b = 15 => a = 5 x 15 = 75
=> Total people:
T = a + b = 15 + 75 = 90

Siobhan scores 4 out of 10 marks in a science test,
what is her score as a percentage?
Answer:
40 percent
Step-by-step explanation:
covert fraction 4 out of ten is 40 %
Answer:
40%
Step-by-step explanation:
A percentage is basically x/100.
Therefore, if we convert Siobhan's mark into a fraction, we get 4/10. Then, by converting the fraction to fit x/100, we get 40/100 (remember, we must do the same to both the numerator and the denominator, so in this case it's multiply them by 10). Now that we have x, we can fit that into the answer to get 40%.

A. (4, 11)
B. (1, 3)
C. (-2, -7)
D. (1, -2)

What is the solution set to the equation x^2+6x+3=0
Answer:
That is a quadratic equation in which
a = 1
b = 6
c = 3
The quadratic formula is:
x = [-b +- sqr root (b^2 -4*a*c)] / 2*a
x = [-6 +- sqr root (36 -4 * 1 * 3)] / 2
x1 = [-6 + sqr root (24)] / 2
x2 = [-6 - sqr root (24)] / 2

A cash card has a starting value of $25. If the card is not used within the first year of its purchase, the value on the card begins to decrease by $2.50 per month.
The relationship between the number of months after the first year and the amount remaining on the card is ____________. (continuous, discrete)
The independent variable is the ___________. (amount remaining on the card, numbers of months after the first year)
The dependent variable is the _____________. (amount remaining on the card, numbers of months after the first year)
Answer:
The relationship between the number of months after the first year and the amount remaining on the card is discrete.
The independent variable is the
number of months after the first year.
The dependent variable is the
amount remaining on the card.
The answers are; The relationship between the number of months after the first year and the amount remaining on the card is discrete.
The independent variable is the number of months after the first year.
The dependent variable is the amount remaining on the card.
What is dependent and independent variables?The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Given that, A cash card has a starting value of $25. If the card is not used within the first year of its purchase, the value on the card begins to decrease by $2.50 per month.
The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse, which meant that, when the number of months after the first year increases, the amount on the remaining car decreases, linearly.
The Independent variable is the numbers of months after the first year.
The Dependent variable is the amount on the remaining card, because this amount depends on the time it has passed since the first year, which is our independent variable.
If we call "Y" our dependent variables and "X" our Independent variable, This relationship can be written as Y= 25 - 2.5x.
If no months had passed since the first year, then x= 0 and the amount in the card equals $25, while if one month has passed since the first year, x= 1 and y= 22.5 (The amount in the card in this case is $22.5.)
Hence, The answers are a) discrete b) numbers of months after the first year c) amount remaining on the card

If the two cars are now a straight-line distance of 17 kilometers apart, how far has the northbound car traveled?
Answer:
Step-by-step explanation:
The northbound car has traveled a distance of 6.2 miles.
Step-by-step explanation:
Step 1:
The eastbound car has traveled a distance of 5 miles and if a straight line is drawn between the two car's positions it would measure 8 miles.
This forms a triangle which has a hypotenuse measuring 8 miles while one of the other sides measures 5 miles.
Assume the distance traveled by the northbound car is x miles.
Step 2:
So the northbound car has traveled a distance of 6.244 miles. Rounding this off, we get 6.2 miles.
The volume of a cylinder is 1029pi cmcubed. The radius of the base of the cylinder is 7 cm. What is the height of the cylinder?
Answer:
Height is 21cm
Step-by-step explanation:
Volume of the cylinder = 1029pi
Base area = 7x7xpi = 49pi
Therefor the height = 1029pi/49pi=1029/49 = 21cm
Answer:
21 cm.
Step-by-step explanation:
V = π r^2 h
1029π = π * 7^2 * h The π is common so:
1029 = 7^2 h
h = 1029 / 49
= 21 cm.

Answer:
x = 2.5
y = 6.5
Step-by-step explanation:
You can solve this by setting the two equations equal to each other, like so:
x + 4 = 3x - 1
Subtract x from both sides:
x + 4 = 3x - 1
-x - x
__________
4 = 2x - 1
Add 1 to both sides:
4 = 2x - 1
+1 + 1
_________
5 = 2x
Divide by 2:
2.5 = x
Plug in 2.5 for x into the equation:
y = x + 4
y = 2.5 + 4
y = 6.5
