You have 10 cups of a cleaning solution that is 10% white vinegar and 90% water. You want the mixture to be 50% white vinegar and 50% water. How many cups of white vinegar do you need to add to the mixture?
Answers
x-->volume of white vinegar you need to add to the mixture (measured in cups)
then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
the volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50multiply both sides by (10+x) and then simplify
(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8
the answer is
you need to add 8 of a cup of the pure vinegar to the mixture
To change a mixture that is 10% vinegar and 90% water to a 50-50 mixture, one would have to add 8 more cups of vinegar. This is because there are already 9 cups of water in the 10 cup solution, so adding 8 more cups of vinegar will total to 9 cups of vinegar and 9 cups of water.
Explanation:This question can be tackled using a simple mathematical approach. You already have a mixture that is 10% vinegar and 90% water, which means you have 1 cup of vinegar in your 10 cups of solution (because 10% of 10 cups is 1 cup). To get a 50-50 mixture, you also need the amount of water to equal the amount of vinegar. Since you already have 9 cups of water in the solution, you need to add 8 more cups of vinegar to balance it out and get a 50% solution. So you'll need to add 8 cups of white vinegar to your mixture in order to attain a balance of 50% vinegar and 50% water.

Answers
The expression x divided by 80 for x = 8/9 is equal to 1/90.
Option D is the correct answer.
We have,
To evaluate x divided by 80 for x = 8/9, we substitute the value of x into the expression and perform the division:
(x) / 80 = (8/9) / 80
To divide fractions, we multiply the numerator by the reciprocal of the denominator:
(8/9) / 80 = (8/9) x (1/80)
Next, we simplify the multiplication:
(8/9) x (1/80) = 8 / (9 x 80) = 8 / 720
Simplifying the fraction further:
8 / 720 = 1 / 90
Therefore,
x divided by 80 for x = 8/9 is equal to 1/90.

Slope ST: -3/2
Slope TU: 4/6 = 2/3
Slope UR: -1/5
Sides RS and TU have the same slope, so they are parallel.
The slope of side ST is the negative reciprocal of the slopes of sides RS and TU, so side ST is perpendicular to sides RS and TU.
Side UR is not parallel or perpendicular to any other side.

Answers
_____
f(x) = 2(x^4 -1)
Answer:
The degree of the polynomial function will be 4.
Step-by-step explanation:
The table shows the ordered pairs for a polynomial function, f.
[tex]x[/tex] -2 -1 0 1 2 3 4
[tex]f(x)[/tex] 30 0 -2 0 30 160 510
Now, to get the degree of the polynomial, it is required to get the difference of the value of function. When the value of the function becomes equal, then the number of step or difference will be its degree.
So, the first difference of the function will be,
[tex]0-30=-30\\ -2-0=-2\\0-(-2)=2\\30-0=30\\160-30=130\\510-160=350[/tex]
Now, the second difference of the function will be,
[tex]-2-(-30)=28\\2-(-2)=4\\30-2=28\\130-30=100\\350-120=220[/tex]
Now, the third difference of the function will be,
[tex]4-28=-24\\28-4=24\\100-28=72\\220-100=120[/tex]
Now, the fourth difference of the function will be,
[tex]24-(-24)=48\\72-24=48\\120-72=48[/tex]
So, the fourth difference of the function is equal and hence, the degree of the polynomial function will be 4.

Which equation is in slope-intercept form and represents a line with slope 3 through the point (9, –4)?
y=3x+21
y=3x-31
-3x+y=-31
-3x+y=21
Answers
[tex]y = mx + q[/tex]
Where m is the slope and y is the y-intercept:
[tex]y = 3x + q[/tex]
To find q (y-intercept), substitute the coordinates of the point (9, -4) in the equation of the line and solve it as an equation:
-4=3(9)+q
-4=27+q
q=-27-4=-31
The equation of the line is: y=3x-31
The equation in slope-intercept form representing a line with a slope of 3 and passing through the point (9, -4) is y = 3x - 31. This is found by substituting the point coordinates into the slope-intercept equation and solving for the y-intercept.
The question involves finding an equation in slope-intercept form that represents a line with a given slope that passes through a specific point. Slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept. Given the slope of 3 and the point (9,
–4), we can find the correct equation by substituting into the slope-intercept form and solving for b.
The correct equation must satisfy the condition that when x is 9, y is –4. Let's use this condition to solve for b:
y = mx + b
–4 = 3(9) + b
–4 = 27 + b
b = –4 - 27
b = –31
Therefore, the equation of the line is y = 3x – 31. This is the only equation among the choices that is in slope-intercept form and satisfies the given conditions.

Selection B is appropriate.
Answer:
The correct option is B.
Step-by-step explanation:
The given number is 0.5.
If a number can be defined as a/b where b≠0, then it is called a rational number.
We need to rewrite the given number in the form of a/b using integers.
Multiply and divide the given number by 10 to remove the decimal from the given number.
[tex]0.5\times \frac{10}{10}[/tex]
On simplification we get
[tex]\frac{0.5\times 10}{10}[/tex]
[tex]\frac{5}{10}[/tex]
Here a=5 and b=10 both are integers.
The given number 0.5 is a ration number because it can be written as 5/10.
Therefore the correct option is B.
