Solve for x and all missing angles

Answer:

y = 1/5 x + 5

Step-by-step explanation:

20y- 4x = 100

Slope intercept form is y = mx+b  where m is the slope and b is the y-intercept.

Solving the equation for y

20y = 4x+100

Divide each side by 20

y = 4x/20 + 100/20

y = 1/5 x + 5

The slope is 1/5 and the y-intercept is 5

Answer:

y = 3

x = 5

From the information provided in this question, it is not possible to accurately determine the proportion of winning actresses who were between 30 and 40 years old when they won the Oscar or the shape of the distribution.

The histogram only provides the frequencies (proportions) of actresses at different age ranges (e.g. 0.39, 0.40, 0.41, 0.45), but it does not provide information about the actual ages or the number of actresses.

In order to determine the proportion of winning actresses within a specific age range, additional information such as the number of actresses in each age group or a plot of the actual ages would be necessary. Similarly, the shape of the distribution cannot be determined accurately based on the information provided, as the histogram only provides the frequencies.

Therefore, the information provided is not sufficient to answer the questions asked.

Answer:45

Step-by-step explanation: Search math w ay on the internet for clarification and any further math questions :)

Answer: 45

Step-by-step explanation:

1. Convert any mixed numbers to fractions then you'll have: [tex]\frac{-15}{1}[/tex] ÷ [tex]\frac{-1}{3}[/tex]

2. Then you multiply the numbers across from each other. (both numerators and denominators)

So, it would then be [tex]\frac{-45}{1-}[/tex]

(remember, when multiplying or dividing negatives and positives, a negative to a positive (vice versa) will always come out to be a negative, and a positive to a positive or negative to a negative, it'll always be a positive)

3. Simplify [tex]\frac{-45}{-1}[/tex], this means you divide  -45 into -1, remember from the bolded phrase, this means it'd be a positive 45

So your answer is POSITIVE 45

Reduced form of given fraction is (2 + n)/7

An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.

Given expression

(2x + nx - 2y - ny)/(7x - 7y)

It can be written as

[(2x - 2y) + (nx - ny)]/(7x - 7y)

Factoring out common factors

[2(x - y) + n(x - y)]/7(x - y)

Again factoring out common factor

(x - y)(2 + n)/7(x - y)

(2 + n)/7

Hence (2 + n)/7 is reduced form of the given expression.

Using  probability, the possible PINs with 5 digits if digits can be repeated are 3125.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. The fundamental ingredient of probability theory is an experiment that can be repeated, at least hypothetically, under essentially identical conditions and that may lead to different outcomes on different trials.

Given that, The PIN has 5 digits, the digits can be repeated.

The number of possible PINs are 5⁵

= 5 * 5 * 5 * 5 * 5

= 3125

With the ratio of 1 : 2 : 3 : 6, the central angle of the largest sector of the circle is 180°.

A circle is a two-dimensional shape consisting of all points in a plane that are at a given distance from the center. Equivalently, we can define a circle to be the curve traced out by a point that moves in a plane so that its distance from the center (a given point) is constant.

A sector is defined to be a part of a circle that is made of the arc of the circle along with its two radii. The shape of a sector of a circle is identical to the shape of a slice of pie or pizza.

We're given a ratio of 1 : 2 : 3 : 6 of all the 4 sectors of a circle. The largest sector in degrees is indicated by 6 out of 12 (12 being the sum of numbers in the ratio). We know that a circle is divided into 360°. Therefore, the central angle θ of the largest sector is:

θ = 6/12 x 360°

θ = 1/2 x 360°

θ = 180°.

Answer:

Since you know that 15 vases are worth 2,250 rupees, then to find how much 25 cost, you can first find how much each costs individually.

To find how much each vase cost, you can just divide the total cost of 15 vases, and the amount of vases:

2250/15 = 150

Each vase costs 150 rupees.

Now to find how much 25 vases cost, you can just multiply the cost per each flower vase, by the total amount of vases:

150 * 25 = 3,750

25 flower vases cost's 3,750 rupees.

A scale is a collection of values, such as levels or numbers, that are applied to a particular system of measurement or comparison. Scale is the ratio that establishes the relationship between the model and the actual figure. The real figures in smaller units are shown by it on maps. As an illustration, a scale of 1:5 means that 1 on the map is equivalent to the size of 5 in the real world. A framework or application can manage heavier loads if it scales properly.

The total distance between Dylan and Mackenzie is reduced by x feet each time Dylan travels x feet, since Mackenzie travels 2x feet during that time. Therefore, their combined distance of travel is x + 2x = 3x feet.

Since their starting distance apart was 230 feet, and their combined distance of travel is 3x feet, we can write an equation to represent the situation:

230 = 3x

To find the distance each person travels, we can solve for x by dividing both sides of the equation by 3:

230 / 3 = 3x / 3

x = 230 / 3 = 76.67 feet

So, Dylan travels x = 76.67 feet and Mackenzie travels 2x = 2 * 76.67 = 153.33 feet.

To explain this further, the numerator of the equation is the number of ways to choose two motors from the nine available, and the denominator is the number of ways to assign the nine motors to the three production lines. The denominator is calculated by multiplying the number of ways to assign three motors to the first line, three motors to the second line, and three motors to the third line.

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Luke realized that squaring each side of the equation √(3-x) = -16 would lead to an extraneous solution. This happens because squaring each side of the equation changes the direction of the inequality, which may result in solutions that do not actually satisfy the original equation.

The square root of any positive number is always positive, so the left side of the equation is always non-negative. However, -16 is a negative number, so there is no real solution to the equation √(3-x) = -16.
