to get the paint color moss green, 2 parts violet paint mixed with 3 parts yellow paint. how many parts yellow paint should be mixed with 5 parts violet paint and **EXPLAIN THE ANSWER STEP BY STEP!**
Answers
Answer:
7.5 parts yellow
Step-by-step explanation:
The color moss green has violet and yellow paint mixed in the proportion 2 to 3. You want to know the number of parts of yellow paint that should be mixed with 5 parts of violet paint.
ProportionThe proportion can be written different ways. We like to put the unknown value in the numerator. (x is the number of parts of yellow paint)
yellow : violet = 3 : 2 = x : 5
Expressed as fractions, the proportion is ...
[tex]\dfrac{3}{2}=\dfrac{x}{5}\\\\5\times\dfrac{3}{2}=x\qquad\text{multiply by 5}\\\\\dfrac{15}{2}=x=7.5\qquad\text{simplify}[/tex]
7.5 parts yellow paint should be mixed with 5 parts violet paint.

Additional comment
If you kept the proportion as violet : yellow, then the unknown value would be in the denominator. The solution to that proportion requires another step. Here, we just needed to multiply by the denominator value to find the unknown.
Which function has the domain x greater-than-or-equal-to negative 11?
y = StartRoot x + 11 EndRoot + 5
y = StartRoot x minus 11 EndRoot + 5
y = StartRoot x + 5 EndRoot minus 11
y = StartRoot x + 5 EndRoot + 11
Answers
The function y= √(x+11) + 5 has Domain x≥-11 .
The Domain of the function is defined as the set of all possible values , that can be input in the function .
In the question;
it is given that
Option(a)
the function is ,
y = √(x + 11) + 5
the square root is defined only for x≥0,
So, we have x+11≥0
subtracting 11 from both the side , we get
x ≥ -11
hence Domain is x≥-11 .
Option(b)
the function is ,
y = √(x - 11) + 5
we have x-11≥0
Adding 11 to both the side , we get
x ≥ 11
hence Domain is x ≥ 11 .
Option(c)
the function is ,
y = √(x + 5) - 11
we have x+5≥0
subtracting 5 from both the side , we get
x ≥ -15
hence Domain is x ≥ -5 .
Option(d)
the function is ,
y = √(x + 5) + 11
we have x+5≥0
subtracting 5 from both the side , we get
x ≥ -15
hence Domain is x ≥ -5 .
From above we can see that only option(a) has Domain as x ≥ -11.
Therefore , the function y= √(x+11) + 5 has Domain x≥-11 , option(a) is correct .
The given question is incomplete , the complete question is
Which function has the domain x ≥ -11?
(a) y = √(x + 11) + 5
(b) y = √(x - 11) + 5
(c) y = √(x + 5) - 11
(d) y = √(x + 5) + 11

What is isosceles triangle ?Triangles that have two sides at least equally spaced apart are said to be isosceles. As three-sided enclosed polygons with three sides, triangles are known to exist. Depending on the length of their sides, triangles can be categorized as equilateral, isosceles, or scalene.
The three interior angles of a triangle will always have a sum of 180°. A triangle cannot have an individual angle measure of 180°, because then the other two angles would not exist (180°+0°+0°).

If s varies inversely as t and s = 8 when t = 5, find the equation that connects s and t.
Answers
We know that:
- s varies inversely as t
- s = 8 when t = 5
And we must find the equation that connects s and t
To find the equation that connects s and t we must use that
In this case, we can say that s = x and t = y. So, our equations would be
[tex]\begin{gathered} st=k \\ \text{ or,} \\ s=\frac{k}{t} \end{gathered}[/tex]Now, knowing that s = 8 when t = 5 we can replace the values in the first equation

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
A group of hikers tracked how long it took to hike a 20-mile trail.
And, They hiked 3.75 miles in 3 hours, 7.5 miles in 6 hours, and 12 miles in 8 hours.
Now,
Find the proportional as;
For hiked 3.75 miles in 3 hours,
Proportional = 3.75 / 3
= 1.25
For hiked 7.5 miles in 6 hours,
Proportional = 7.5 / 6
= 1.25
For hiked 12 miles in 8 hours,
Proportional = 12 / 8
= 1.5
Thus, The correct relationship between the hikers distance and time is;
No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.
