Given: circle k(O), m AM=125°, m EF=31°, m∠MAF=75°. Find: m∠AME
Answer:
58°
Step-by-step explanation:
If m AM=125°, then m∠AOM=125°.
If m∠MAF=75°, then m∠MOF=150° (because central angle MOF subtends on the same arc as inscribed angle MAF).
Thus,
m∠FOA=360°-150°-125°=85°.
If mEF=31°, then m∠EOF=31° (as central angle subtended on the arc EF).
Hence,
m∠EOA=m∠EOF+m∠FOA=31°+85°=116°.
Angle EOA is central angle subtended on arc EA, angle AME is inscribed angle subtended on arc AE, thus
m∠AME=1/2m∠EOA=58°.
What is the solution of 3 sqrt x+8=-4?
Answer:
[tex]x=-72[/tex]
Step-by-step explanation:
The given equation is [tex]\sqrt[3]{x+8}=-4[/tex].
We cube both sides of this equation to obtain;
[tex](\sqrt[3]{x+8})^3=(-4)^3[/tex].
This implies that;
[tex](x+8)=-64[/tex]
We group similar terms to obtain;
[tex]x=-64-8[/tex]
We simplify the right hand side of the equation to obtain;
[tex]x=-72[/tex]
Therefore x=-72 is the solution of the given equation.
The equation 3 √x + 8 = -4 has no solution. The square root term, when isolated, shows a contradiction since the square root of a non-negative number multiplied by a positive constant cannot be negative.
Explanation:The solution to the equation 3 √x + 8 = -4 involves finding the value of x for which the equation holds true. Given that √4 can be both 2 and -2, we explore the possibility of squaring both sides of an equation to solve for x. However, in this case, since the square root of a number cannot be negative and the original equation involves a square root on the left side, this hints at no solution being possible because the left side (involving the square root) will always be non-negative, and cannot equal a negative number.
Nevertheless, let's attempt to formally solve the equation. Isolating the square root term by subtracting 8 from both sides results in 3 √x = -12. At this point, we encounter a contradiction: the left side represents a non-negative value (since it's 3 times the square root of x), but the right side is negative. This confirms there are no real solutions to the equation because the square root of a non-negative number (x) cannot result in a negative value when multiplied by a positive constant (3).

Last year Jo paid £245 for her car insurance. This year she has to pay £883 for her car insurance. Work out the percentage increase in the cost of her car insurance.
Answer:
260%
Step-by-step explanation:
To solve how much the percentage increase cost of Jo's car insurance is, we first need to list down our variables.
1st year = £245
2nd year = £883
First off, we need to find the difference of the two.
Increase = £883 - £245
Increase = £638
Now to find the percentage increase, we take our increase and divide it by our 1st year's payment and multiply it by 100.
Percentage increase = [tex]\dfrac{638}{245}*100[/tex]
Percentage increase = [tex]2.60*100[/tex]
Percentage increase = 260%
So the percentage increase of last years payment to this years payment is 260%.

What is the factorization or the trinomial below? -2x^3+2x^2+12x
The answer is C because the 2x outside of the brackers must be negative to produce the beginning term. The next terms are positive and two negatives make a positive, therefore we can conclude that there must be a negative inside the brackets too.
Answer: C. −2x(x−3)(x+2)
Step-by-step explanation:
1. Find the Greatest Common Factor (GCF).
GCF=2x
2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2x(2x^3/2x+−2x^2/2x+−12x/2x)
3. Simplify each term in parentheses.
−2x(x^2−x−6)
4. Factor x^2−x−6
−2x(x−3)(x+2)

Jimmy pays $2.52 for each gallon of gas. Which table best represents the relationship between g, the number of gallons purchased, and m, the amount he pays for gas?
The table that best represents the relationship between the number of gallons purchased, g, and the amount paid for gas, m, will list m as multiples of $2.52 as per the linear relationship g: $2.52 * g.
Jimmy pays $2.52 for each gallon of gas. To find the best table representing the relationship between g, the number of gallons purchased, and m, the amount he pays for gas, we need to create a table where each entry form is the product of g and the price per gallon, which is $2.52.
For each gallon g, the total cost m would be:
For 1 gallon: m = 1 * $2.52 = $2.52
For 2 gallons: m = 2 * $2.52 = $5.04
For 3 gallons: m = 3 * $2.52 = $7.56
...and so on.
This pattern will continue since the relationship is linear, and the table representing it will list the total cost m corresponding to the number of gallons g based on this constant rate of $2.52 per gallon.
the value of y varies directly with x, and when x = 1/4 , y = 25. What is the value of y when x is 2 1/3 need help ASAP
Answer:
[tex]y=233\frac{1}{3}[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]
In this problem we have
For [tex]x=1/4, y=25[/tex]
Find the value of k (constant of proportionality)
[tex]y/x=k[/tex] -----> [tex]k=25/(1/4)=100[/tex]
The linear equation is
[tex]y=100x[/tex]
Find the value of y when the value of [tex]x=2\frac{1}{3}[/tex]
substitute the value of x in the equation but first convert to an improper fraction
[tex]x=2\frac{1}{3}=\frac{2*3+1}{3}=\frac{7}{3}[/tex]
[tex]y=100(\frac{7}{3})=\frac{700}{3}[/tex]
convert the result in mixed number
[tex]\frac{700}{3}=\frac{699}{3}+\frac{1}{3}=233\frac{1}{3}[/tex]

The density of a fish tank is 0.5 fish per feet3. There are 30 fish in the tank. What is the volume of the tank
Answer:
60 cubic feet.
Step-by-step explanation:
The fish are 0.5 per cubic foot. This means 1 fish occupies 2 cubic feet. So if there are 30 fishes then there must be 60 cubic feet.
Answer:Instead of dividing the diameter by two to get the radius, the coworker multiplied the diameter by two, getting a value of 340 feet for the radius. Here’s the incorrect calculation:
volume of a cylinder ≈ 3.14 × (radius)2 × height
= 3.14 × (340 ft)2 × (60 ft)

Lisa has 2 red dresses, 3 green dresses and x blue dresses hanging in her closet. If lisa chooses one dress at random, the probability that lisa will choose a red dress is 25%. How many blue dresses does lisa have?
Lisa has a total of 8 dresses in her closet. There are 2 red dresses, 3 green dresses, and the remaining 3 are blue dresses.
Explanation:The subject of the question is probability in Mathematics. In the problem, Lisa has a total of 2 red dresses and 3 green dresses. The quantity of blue dresses is represented by 'x'. It is stated that the probability of choosing a red dress is 25%. Each dress in her closet is an outcome for this probability calculation.
So, in total, she has 2(red dresses) + 3(green dresses) + x(blue dresses) = 100% of the dresses or total outcomes. Since the probability of picking a red dress is 25%, then 2 (red dresses) are 25% of the total outcomes.
To work out the total number of outcomes (total dresses), we calculate 100% ÷ 25% = 4, and then multiply this by the number of red dresses (which is 2), giving us 4*2 = 8 dresses in total.
As we know there are 2 red dresses and 3 green dresses, that leaves 8 (total dresses) - 2 (red) -3 (green) = 3 blue dresses. Thus, Lisa has three blue dresses in her closet.

Lisa has 6 blue dresses.
Explanation:To find the number of blue dresses Lisa has, we need to set up an equation using the given information.
Lisa has 2 red dresses, 3 green dresses, and x blue dresses. The total number of dresses is 2 + 3 + x = 5 + x.
The probability of choosing a red dress is 25%, which can be written as 0.25.
This means that the number of red dresses divided by the total number of dresses equals 0.25. So, we have 2 / (5 + x) = 0.25.
Solving this equation for x, we find that Lisa has 6 blue dresses.

huong and kathyrn each day impeoved their yards by planting rose bushes and ornamental grass. they bought their supplies from the same store. huong spent $70on 14 rose bushes and 7 bunches of ornamental grass. kathyrn spent $71 on 5 rose bushes and 14 bunches of ornamebtal grasa. what is the cost of one rose bush and the cost od ine bunch of ornamental geass?
Answer:
One rose bush = $3
One bunch of ornamental grass = $4
Step-by-step explanation:
We can set up a system of equations to solve for this. Let cost of 1 rose bush be r and cost of 1 ornamental grass be g. Thus we can form 2 equations:
[tex]14r+7g=70\\5r+14g=71[/tex]
We can multiply the first equation by -2 so that we can eliminate g. Thus, we have:
[tex](*-2)14r+7g=70\\5r+14g=71\\-------\\-28r-14g=-140\\5r+14g=71\\--------\\-23r=-69\\r=\frac{-69}{-23}=3[/tex]
Thus, 1 rose bush is $3. Now plugging in r = 3 into the first original equation, we can solve for g:
[tex]14r+7g=70\\14(3)+7g=70\\42+7g=70\\7g=70-42\\7g=28\\g=\frac{28}{7}=4[/tex]
Thus, 1 bunch of ornamental grass is $4.

Apply the definition of subtraction and properties of operations to find the result.
1/8-3/7-1/8
Final answer:
To find the result of 1/8 - 3/7 - 1/8, we need to find a common denominator for the fractions and then subtract them.
Explanation:
To find the result of 1/8 - 3/7 - 1/8, we need to apply the definition of subtraction and properties of operations. First, let's find a common denominator for the fractions. The common denominator for 8 and 7 is 56. Multiply the numerator and denominator of 1/8 by 7 to get 7/56. Multiply the numerator and denominator of 3/7 by 8 to get 24/56. Now subtract the fractions: (7/56) - (24/56) = -17/56. Finally, subtract 1/8 from -17/56. Multiply the numerator and denominator of 1/8 by 7 to get 7/56. Subtract the fractions: (-17/56) - (7/56) = -24/56.
Another term for measurement data is
A) quantitative data.
B) categorical data.
C) qualitative data.
Eliminate
D) bivariate data.
Measurement data refers to numerical information gathered by quantifying objects or events, known as quantitative data. It contrasts with qualitative, or categorical data, which describes non-numeric attributes. Quantitative data can be further classified into discrete or continuous based on the nature of the measurement.
Explanation:The term measurement data refers to data that quantifies objects or events. This type of data can be classified as either quantitative discrete or quantitative continuous, depending on whether the data can take on only integer values or any values within a continuous range. Therefore, another term for measurement data is A) quantitative data. Quantitative data is always expressed in numbers and includes measurements such as length, mass, and time.
For example, measuring the height of a plant in centimeters yields quantitative data because it provides a numerical measurement of the plant's height. Similarly, recording the number of books a person reads in a month gives quantitative data because it counts the books. This contrasts with qualitative or categorical data, which describes attributes or characteristics that cannot be measured numerically, such as the colors of houses or types of pets.
In summary, measurement data is best described as quantitative data because it involves numerical measurements or counts, making it essential for mathematical analysis and supporting scientific findings.
