The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." Jada mixes 24 ml of blue water with 9 ml of red water. Andre mixes 16 ml of blue water with 9 ml of red water. Which person will get a color mixture that is the same shade as Perfect Purple Water? Jada Andre
Answer:Jada will get same shade as Perfect Purple Water
Step-by-step explanation:
STEP 1
To get the right recipe for Perfect purple water, every new mixture must have an equivalent ratio as the ideal mixture
The ideal mixture is given as
8ml blue water and 3 ml red water.
Step 2
Andre mixes 16ml blue water with 9ml red water
[tex]\frac{8ml}{3ml}[/tex] is not equivalent to [tex]\frac{16ml}{9ml}[/tex]
Because dividing Andre's mixture by a common value will not give the equivalent ratio of the ideal recipe
[tex]\frac{16ml}{9ml}[/tex] [tex]\frac{/}{/}[/tex] [tex]\frac{3}{3}[/tex] =[tex]\frac{5.3ml}{3ml}[/tex]
Jada mixes 24ml blue water with 9ml red water
[tex]\frac{8ml}{3ml}[/tex] is equivalent to [tex]\frac{24ml}{9ml}[/tex]
Because dividing Jada's mixture by a common value gives the equivalent ratio of the ideal recipe
[tex]\frac{24ml}{9ml}[/tex] [tex]\frac{/}{/}[/tex] [tex]\frac{3}{3}[/tex] =[tex]\frac{8ml}{3ml}[/tex]
This shows that Jada got the right recipe and will get same shade as Perfect Purple Water but in a higher quantity, 3 times the right recipe for Perfect Purple Water

You had $24 to spend on eight
raffle tickets. After buying them
you had $8. How much did each
raffle ticket cost?
Answer:
$2 each ticket is 2 dollars
Question 3: Jason
receives $40 from
selling 5 adult tickets
and 8 students tickets.
.write an equation to
represent the situation.
Answer:
$40 = 5a + 8s
Step-by-step explanation:
For this question all we need to know is that $40 is equal to 5 prices of the adult tickets plus the 8 prices of the student tickets. From here we can just give a variable to each price and make an equation, like so
Let "a" be the price of the adult ticket and
Let "s" be the price of the adult ticket, then....
$40 = 5a + 8s
(Just to make sure you understand I will repeat. 5 comes from he fact hat there were 5 adult tickets sold which means that there is 5 adult ticket prices in the $40, and exactly the same reasoning goes for the student tickets, 8 students tickets were sold which means the is 8 prices of the student ticket inside the $40.)
[tex]x^a=y^b=z^c \\xyz=1\\ab+bc+ca=?[/tex]
Answer:
ab+bc+ca=0
Step-by-step explanation:
We are given:
[tex]x^a=y^b=z^c[/tex]
xyz=1
Separating equations:
[tex]x^a=z^c[/tex]
[tex]y^b=z^c[/tex]
Solving the first equation for x:
[tex]\displaystyle x=z^\frac{c}{a}[/tex]
Solving the second equation for y:
[tex]\displaystyle y=z^\frac{c}{b}[/tex]
Substituting in
xyz=1:
[tex]\displaystyle z^\frac{c}{a}z^\frac{c}{b}z=1[/tex]
Adding the exponents:
[tex]\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=1[/tex]
Since [tex]1=z^0[/tex]:
[tex]\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=z^0[/tex]
The base is z on both sides so we get rid of them:
[tex]\displaystyle \frac{c}{a}+\frac{c}{b}+1=0[/tex]
Multiplying by ab:
bc+ac+ab=0
Reordering:
ab+bc+ca=0

What’s the answer? True or false
Answer:
True because it is true thank U
Pleaseeeee helpppp !!!!!!!! Will mark Brianliest !!!!!!!!!!!!!
Answer:
so this uses proportions.
you need to find the side BF which is proportional to the side BF.
You do:
9/6=x/42
and cross multiply
9*42=6*x
378=6x
divide by 6 on both sides
x=63
the answer is 63
Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE

What is the slope and equation of a horizontal line ?
Answer:
Step-by-step explanation:
The equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx + b becomes y = 0x +b y = b. Also ,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.
Answer:
Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.
Step-by-step explanation:
Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.

===============================================
Work Shown:
[tex]V = \frac{4}{3}\pi*r^3\\\\V = \frac{4}{3}\pi*(2t)^3\\\\\frac{4000\pi}{3} = \frac{4}{3}\pi*(2t)^3\\\\4000\pi = 4\pi*(2t)^3\\\\1000 = (2t)^3\\\\(2t)^3 = 1000\\\\(2t)^3 = 10^3\\\\2t = 10\\\\t = 5\\\\[/tex]
-----------------
Notes:
In line 2, I replaced r with 2t because the radius r is increasing at a rate of 2 cm per second. So if t is the number of seconds, then 2t is the radius in cm at time t.In line 4, I multiplied both sides by 3 to clear out the fractions. On the next line, I divided both sides by 4pi.Divide the polynomials.

Find the unit price of each item, rounding answers to the nearest tenth of a cent. A) 4 lbs for $2.37 b) 15 lbs for $8.57 c) 25 lbs for $13.59 Which bag (4, 15, or 25) is the best deal?
Answer:
A. $0.59
B. $0.57
C. $0.54
The best deal is 25 lbs for $13.59
Step-by-step explanation:
A) 4 lbs for $2.37
Units price (price per lb) = $2.37 / 4
= $0.5925
Approximately $0.59
b) 15 lbs for $8.57
Price per lb = $8.57 / 15
= $0.5713
Approximately $0.57
c) 25 lbs for $13.59
Price per lb = $13.59 / 25
= $0.5436
Approximately $0.54
Which bag (4, 15, or 25) is the best deal?
The best deal is 25 lbs for $13.59
