Answers:
She made __50__ grams of __20__% solution
-------------------------------------------------------------------
Work Shown:
There's 10+40 = 50 grams of stuff overall (that "stuff" being salt and water). Of this total, 10 grams are salt so 10/50 = 1/5 = 0.20 = 20% is salt. Therefore this is a 20% salt solution.
We can say "20% solution" or "20% salt solution" to be more specific of what kind of chemical mix it is.
Which of the following statements is true about lines 3y + 2x - 9 = 0 and 12y + 8x - 5 = 0? They are parallel They are perpendicular They are parallel to the x-axis They are parallel to the y-axis
Answer:
The statement "They are parallel" is true.
Step-by-step explanation:
The general form of the equation of a straight line is:
[tex]Ax+By+C=0[/tex]
where A, B, and C are three real numbers.
A line parallel to the x-axis has this form [tex]y=C[/tex] where C is a real number.
A line parallel to the y-axis has this form [tex]x=C[/tex] where C is a real number.
From the lines given none of these have the form of a line parallel to the x-axis or the y-axis. Therefore the statements "They are parallel to the x-axis" and "They are parallel to the y-axis" are false.
Two non-vertical lines in a plane are parallel if they have both:
the same slopedifferent y-interceptsTwo non-vertical lines are perpendicular if the slope of one is the negative reciprocal of the slope of the other.
To check if the lines are parallel of perpendicular you must transform these lines into the slope/intercept form
[tex]y=mx+b[/tex]
where m represents the slope and b represents the y-intercept.
The slope/intercept form for the first line is:
[tex]3y+2x-9=0\\\\3y+2x-9-2x=0-2x\\\\3y-9=-2x\\\\3y-9+9=-2x+9\\\\3y=-2x+9\\\\y=\frac{-2x+9}{3}\\\\y=\frac{-2}{3}x+3[/tex]
The slope/intercept form for the second line is:
[tex]12y+8x-5=0\\\\12y+8x-5-8x=0-8x\\\\12y-5=-8x\\\\12y-5+5=-8x+5\\\\12y=-8x+5\\\\y=\frac{-8x+5}{12}\\\\y=\frac{-2}{3}x+\frac{5}{12}[/tex]
We can see that the lines have the same slope and different y-intercepts. Therefore the statement "They are parallel" is true.
We can check our work with the graph of the lines.

A line with a slope of 33 passes through (2,5)2,5. Which choice is an equation of this line? a)y+5=3x+2 b)y-5=3x-2 c) y-5=(x-2) d)y-2=3(x-5)
Answer:
y - 5 = 3 . (x - 2)
Step-by-step explanation:
A linear equation can be written in point-slope form.
y - y₁ = m. (x- x₁)
where
x is the independent variable
y is the dependent variable
(x₁, y₁) is an ordered pair representing a point through which the line passes
m is the slope
Given the slope is 3 (m = 3) and the line passes through the point (2, 5) (x₁ = 2, y₁ = 5), we can write the point-slope form of the linear equation.
y - 5 = 3 . (x - 2)

a rectangle is 1/3 yards long and 2/3 yards wide.
what is the area of the rectangle?
enter your answer in the box as a fraction in simplest form
[tex] \frac{?}{?} \: {yd}^{2} [/tex]
Final answer:
The area of a rectangle with dimensions of 1/3 yards by 2/3 yards is calculated using the formula length × width, resulting in an area of 2/9 square yards. This value is already in simplest form.
Explanation:
The question asks us to find the area of a rectangle that is 1/3 yards long and 2/3 yards wide. The formula to calculate the area of a rectangle is length × width. Therefore, to find the area, we multiply 1/3 yards by 2/3 yards.
Area = (1/3) yd × (2/3) yd = 2/9 yd²
This calculation shows that the area of the rectangle is 2/9 square yards. It is important to express the answer in simplest form, as the question requests, and 2/9 is already in its simplest form.

According to m&ms web site, each package of the milk chocolate candies typically contain 14% brown, 13% red, 14% yellow, 16% green, 24% blue, and 20% orange m&ms. you go to the store and buy a standard-sized package. when you open it, you find that it contains 51 m&ms, distributed as follows: color brown red yellow green blue orange frequency 8 4 10 7 11 11 over the long run, you know that the probability of selecting a blue or an orange m&m will be 44% because these outcomes are: finite. disjoint. discrete. none of the answer choices is correct.
Answer: Disjoint
Step-by-step explanation: Selecting specific colors in a m&m's pack is disjoint because the events cannot occur at the same time, i.e., when you take one m&m's, it can be blue and orange at the same time.
To determine the probability of disjoint or mutually exclusive events, you can find their probability by adding the probability of each event.
In the question, it is asked the probability of selecting a blue or an orange.
Probability of a blue:
P(b) = [tex]\frac{11}{51}[/tex]
Probability of an orange:
P(o) = [tex]\frac{11}{51}[/tex]
Probability of one OR the other:
P(b OR o) = P(b) + P(o)
P(b OR o) = [tex]\frac{11}{51} + \frac{11}{51}[/tex]
P(b OR o) = [tex]\frac{22}{51}[/tex]
P(b OR o) ≈ 0.44 or 44%
The probability of blue or orange m&m's is 44%, and the events are disjoint.
According to the provided probabilities on the M&M's website, the probability of choosing a blue or an orange M&M is a combined 44%. These outcomes are described as discrete, as they are distinct and countable events in the context of probabilities.
Explanation:The question is based on probabilities related to the distribution of M&M colors in a package, particularly focusing on the number of orange M&Ms and the number of yellow M&Ms. When analyzing the distribution of M&M colors, we utilize concepts from statistics such as uniform distribution and binomial distribution to assess the likelihood of pulling a particular color from a bag. If the M&Ms had a uniform distribution, we would expect each color to appear with equal probability; however, the provided probabilities for each color do not align with a uniform distribution.
In the long run, the probability of selecting a blue or an orange M&M is 44% combined, based on the provided percentages on the M&M's website (24% blue and 20% orange). These outcomes are discrete, as they represent distinct countable outcomes. The terms 'finite', 'disjoint', and 'discrete' are all descriptions of different characteristics of statistical outcomes. 'Finite' refers to a set that has a limited number of outcomes, 'disjoint' indicates that the events cannot happen at the same time, and 'discrete' encompasses outcomes that are countable and not continuous.
alvin's age is two times elga's the sum of their ages is 87 what is elga's age?
By forming an algebraic equation based on the given information, we find that Elga's age is 29 years.
Explanation:This question belongs to the category of Algebraic equations. We know that Alvin's age is two times Elga's, so we could represent Alvin's age as 2E, where E represents Elga's age.
The problem also tells us that the sum of their ages equals 87. That means we can form this equation: E + 2E = 87.
Combining like terms, we get 3E = 87. Finally, dividing each side by 3, we find the value of E (Elga's age).
So, Elga's age is 87 / 3, which equals 29 years.

Quadrilateral ABCD is inscribed in this circle.
What is the measure of ∠A ?
Enter your answer in the box.
____°
Answer:
Measure of ∠A is 106°
Step-by-step explanation:
We are given that, 'Quadrilateral ABCD is inscribed in the circle'.
So, we get that,
'ABCD is a cyclic quadrilateral' i.e. The sum of the opposite interior angles is 180°.
Thus, we have,
∠A +∠C = 180°
i.e. ∠A + 74° = 180°
i.e. ∠A = 180° - 74°
i.e. ∠A = 106°
Thus, the measure of ∠A is 106°.
find the equation of the circle with center at (-3,1) and through the point (2,13)

Answer:
E2020
Step-by-step explanation:
The four successive terms of the given ap series by rule [tex]a_{n}[/tex] = 4 - 2n will be 2, 0, -2, and -4.
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
Natural number = 1,2,3,4,5,6,7,8...
Now it has the same difference between any two consecutive terms d =2-1 = 3-2.
Given the rule for nth term of ap series
[tex]a_{n}[/tex] = 4 - 2n
Now,
First term (n = 1) ⇒ 4 - 2(1) = 2
Second term (n =2) ⇒ 4 - 2(2) = 0
Third term (n = 3) ⇒ 4 - 2(3) = -2
Fourth term (n = 4) ⇒4 - 2(4) = -4
Hence "The four successive terms of the given ap series by rule [tex]a_{n}[/tex] = 4 - 2n will be 2, 0, -2, and -4.".

What is the length of YX¯¯¯¯¯¯? Enter your answer as a decimal in the box. Round your final answer to the nearest hundredth. m_https://static.k12.com/nextgen_media/assets/8107298-NG_GMT_SemB_10_UT_06.png'
Final answer:
To find the actual length represented by YX, we set up a proportion using the given scale length and solve for the unknown length x. Using one of the provided scale ratios, such as 0.5 inches representing 2000 miles, we perform cross-multiplication to solve for x and determine the accurate length after calculations.
Explanation:
The student is asked to find the actual length represented by the segment YX on a map or a diagram when given a scale length. To solve the problem, we set up a proportion based on the scale provided and solve for the unknown length x. There are different given scales in the prompts such as 0.5 inches representing 2000 miles, 8 inches representing an unknown number of miles, and 3 inches also representing an unknown number of miles.
Example with a Scale Ratio of 0.5 inches to 2000 miles
To solve for x when the scale is 0.5 inches on the map corresponds to 2000 miles in reality, we use a proportion: 1 inch/2000 miles = 0.5 inches/x miles. After cross-multiplication, we get x = 0.5 inches * 2000 miles, which after calculation will give us the value of x rounded to the nearest hundredth.
Example with a Scale Ratio of 0.25 inches to 2000 miles
Similar steps are taken if the scale is 0.25 inches. We set up the proportion 1 inch/2000 miles = 0.25 inches/x miles and solve for x after cross-multiplication.

which equation can be solved to find x, the measure of BD in the diagram below?
Answer:
A. [tex]\frac{1}{2} (233^{o}-x)=53^{o}[/tex]
Step-by-step explanation:
Let x be the measure of arc BD.
Since we know that an angle formed by two intersecting tangents equals one-half the difference of the measures of the intercepted arcs (the major arc-minus the minor arc).
[tex]\text{ Measure of tangent-tangent angle}=\frac{1}{2} (\text{measure of major arc-measure of minor arc})[/tex]
We can see from our given graph that the tangent-tangent angle's measure is 53 degree. The measure of its intercepting major arc equals 233 degrees and minor arc equals x.
Upon substituting our given values in above formula we will get,
[tex]53^{o}=\frac{1}{2} (233^{o}-x)[/tex]
[tex]\frac{1}{2} (233^{o}-x)=53^{o}[/tex]
Therefore, the equation that can be solved to find x (the measure of arc BD) will be [tex]\frac{1}{2} (233^{o}-x)=53^{o}[/tex] and option A is the correct choice.
ordered: 0.5 mg
Available: 2 mg/ml
how many mls should be given?
Final answer:
The patient should be given 0.25 mls of the medication.
Explanation:
To calculate the volume of medication a patient should be given, we can use a basic formula that relates the ordered dose, the concentration of the medication available, and the volume required to deliver the ordered dose. In this case, the student has been asked to determine how many milliliters (mls) of medication to administer when 0.5 mg is ordered and the medication concentration available is 2 mg/ml.
The formula to use is:
Dose ordered (mg) / Concentration of medication (mg/ml) = Volume to administer (ml)
So for this problem:
0.5 mg / 2 mg/ml = 0.25 ml
Therefore, the patient should be given 0.25 mls of the medication.
Complete the table of values for the linear equation -2x-5=30 brainly. Enter your answers in the boxes.
The value of x is x = -17.5.
The linear equation in question is -2x - 5 = 30. To complete a table of values for this equation, solve for x first:
Add 5 to both sides of the equation to isolate the term with x: -2x = 35.
Divide both sides by -2 to solve for x: x = -17.5.
Now that you have the value of x, you can fill in the table with x = -17.5, since a table of values typically includes various values for x and the corresponding values for the equation. However, in this case, the equation is simply solved for a single value of x without needing different values for it.
