A students cost for last semester was 2000 she spent 320 on books. What percent of last semester was cost in books

Answers

The percentage of money spent on books to that of cost for last semester is 16%

The cost for last semester was 2000.

The cost books was 320.

The percentage formula = part/whole × 100

Part = 320

Whole = 2000

Equation = 320/2000× 100

Alternate angles are angles that occur on opposite sides of the transversal line and have the same size.

Both are obtuse angles and are on the opposite side of the transversal line

Answer:

∠KLC is the alternate angle of ∠BKL

Step-by-step explanation:

Alternate angles are angles that are opposite of one another and on two different parallel lines created by an intersecting line (also known as a transverse line).

In this case, the parallel lines are lines A↔B and C↔D, and the transverse line is M↔N. Therefore, the alternate angle from ∠BKL is ∠KLC.

Answers

The rational numbers - 5 / 6 and - 7 / 10 are equivalent to - 25 / 30 and - 21 / 30, respectively. Then, the relationship is that - 5 / 6 is the less than - 7 / 10 as - 25 < - 21.

What is the relationship between two rational numbers?

Rational numbers are real numbers of the form m / n, where m and n are integers and n is not zero. In this problem we need to determine the relationship between two rational numbers, this can be done by amplifying the two rational numbers to a form with the same denominator and then compare the two numerators.

First, find the least common multiple of the two denominators:

6 = 2 × 3

10 = 2 × 5

L.C.M. = 2 × 3 × 5 = 30

Second, amplify each rational number:

- (5 × 5) / (6 × 5) = - 25 / 30

- (7 × 3) / (10 × 3) = - 21 / 30

Third, compare the numerators of the fraction found in the previous step:

Since - 25 < - 21, then - 5 / 6 < - 7 / 10.

Carlos is moving to a new city and looking for a new job. He wants to rent an apartment, and he is willing to use half of his monthly paycheck for rent and apartment-related fees that he knows will be 200$. He doesn’t know exactly how much he’ll make at his new job yet, but he knows it will be somewhere between $3000 and $4000. Write an inequality and solve an inequality to show the price range David’s apartment will have to be in.

Answers

Answer: The price of the apartment lies in the range of $1300 to $1800

Step-by-step explanation: Because Carlos doesn't exactly know how much  he'll make at his new job but he knows the range will be between 3000$ and 4000$ we will use inequality to solve this problem.

Let the rent on the new apartment = r

let monthly pay of Carlos = x

Given, apartment related fees = 200$

Given he is willing to use half of his monthly pay for rent and apartment related fees combined.

∴rent + apartment related fees = Monthly pay / 2

⇒[tex]r + 200 = \frac{x}{2}[/tex]

⇒[tex]x=2*(r+200)[/tex]

⇒[tex]x=2r+400[/tex]                                                (1)

Given Carlos' monthly pay is in the range of $3000 to $4000

∴[tex]3000\leq x\leq 4000[/tex]

⇒[tex]3000\leq (2r+400)\leq 4000[/tex]                             (from equation (1))

⇒[tex]3000-400\leq 2r+400-400\leq 4000-400[/tex]     (subtracting 400)

⇒[tex]2600\leq 2r\leq 3600[/tex]

⇒[tex]\frac{2600}{2}\leq \frac{2r}{2}\leq \frac{3600}{2}[/tex]                                           (dividing by 2)

2x23=46kg

Answer:

46 kg

Step-by-step explanation:

Ratio of copper to tin in the bronze alloy is 23:2

That means, as a ratio of the entire brass mass, the copper content is in the ratio of 23/(23 + 2) = 23/25

Since the mass of the bronze statue is 50 kg, the mass of copper in it must be 50  x  23/25 = 46 kg

The remaining kg (2/25 of 50 kg) is tin

which of the following options result in a graph that shows expoential decay​

The option that results in a graph that shows exponential decay is Option(b) f(x) = 3(0.7)ˣ.

What is the Exponential Decay Formula?The exponential decay formula helps to determine the rapid decline over time or exponential decline. The exponential decay formula is used to calculate various types of decay, including radioactivity decay, half-life, and population decay.The exponential decay formula is f(x) = abˣ, where a is the initial amount, b is the decay factor and x is the time interval.

According to the question, we have to determine the function that results in a graph that shows exponential decay.

The function will show an exponential decay if the value of b was less than 1 and greater than 0.

As we can notice in the second option, f(x) = 3(0.7)ˣ, where b is equal to 0.7 which is less than one.

we sadly need to do all the multiplications for the whole polynomial in standard form.

the other 3 things we get out of the given form :

we multiply 3 terms, each in x. the result will be x³.

so, we have the 3rd degree.

the leading coefficient is 1, as for the x³ term we get x×x×x = x³. no other number is involved.

the constant term is the extreme on the other end. it is 4×2×1 = 8.

so, now for the full multiplications, that should also show you, why I could make the conclusions above.

(x+4)(x-2)(x+1)

we do this by multiplying first 2 terms with each other, and then we multiply that result by the third term.

remember, we need to multiply every item of one term with every item in the other term.

(x+4)(x-2) = x² -2x + 4x - 8 = x² + 2x - 8

now

(x² + 2x - 8)(x+1) = x³ + x² + 2x² + 2x - 8x - 8 =

= x³ + 3x² - 6x - 8

so, that is already the standard form

In AJKL, JL is extended through point L to point M,
m/JKL = (3x – 16)°, m/LJK = (2x + 15)°, and
m/KLM = (8x – 19)°. Find m/LJK.

Answers

The value of x is 6 and the measure of angle LJK is 27°.

According to the triangle's "angle sum property," a triangle's interior angles add up to 180°.

We have the measure of the following angles,

m∠JKL = ( 3x - 16 )°

m∠LJK = ( 2x + 15 )°

m∠KLM = ( 8x - 19)°

In ΔJKL, JL is extended through point L to point M.

At point L, the measure of angle JLK will be as,

m∠KLM + m∠JLK = 180°

m∠JLK = 180° - m∠KLM

m∠JLK = 180° - ( 8x - 19)°

m∠JLK = ( 199 - 8x )°

Now,

In triangle JKL,

By angle sum property:

m∠JKL + m∠LJK + m∠JLK = 180°

(3x – 16)° + (2x + 15)° + ( 199 - 8x )° = 180°

- 3x + 198 = 180

- 3x = - 18

x = 6°

Therefore,

m∠LJK = ( 2x + 15 )°

m∠LJK = ( 2(6) + 15 )°

m∠LJK = ( 12 + 15 )°

m∠LJK = 27°

The measure of angle LJK is 27°.

write the equation in slope intercept form of the line that passes through the points (-4,8) and (4,6)

Answers

The equation of the line in the slope-intercept form is y = -1/4x + 9

Equation of a line

From the question, we are to determine the equation of the line that passes through the given points.

The given points are (-4, 8) and (4, 6)

Using the formula,

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

x₁ = -4

y₁ = 8

x₂ = 4

y₂ = 6

Thus,

(y - 8)/(x - -4) = (6 - 8)/(4 - -4)

(y - 8)/(x + 4) = -2 / (4 + 4)

(y - 8)/(x + 4) = -2 / 8

(y - 8)/(x + 4) = -1/4

4(y - 8) = -1(x + 4)

4(y - 8) = -x + 4

y - 8 = -1/4x + 1

y = -1/4x + 1 + 8

y = -1/4x + 9

Therefore,

The equation is y = -1/4x + 9

What is the slope of a function?

The slope m=y/x of a straight-line y=mx+b quantifies the change in y for every unit change in x. This can also be interpreted as a kind of measure of "sensitivity''.

Finding the slope of a function is like finding the rate at which the value of y (the dependent variable) changes in relation to x is what this method entails (independent variable).

How to find the slope of a function?

To find the slope of a line that is given with the equation of the line, first you have to write the equation of the line in a slope-intercept form.

Then use inverse operations in order to solve for y so that it is written as y=mx+b. Thereafter you can easily spot the slope since the slope is the coefficient of the x variable, or in other words, the number in front of x.

Answers

The table with the situations that represent or not proportional relationships of distance and time is given at the end of the answer.

Which situation models a proportional relationship?

A situation represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:

y = kx.

One example, in the context of this problem, is the relation between velocity, distance and time, as velocity is distance divided by time, hence:

v = d/t.

The relation between distance and time is given as follows:

distance = velocity x time

distance = v x t.

Hence it will only be proportional if the velocity is constant, that is, if the acceleration is of zero.

Examples of non-proportional situations in the context of this problem are:

A touchdown, as when the play starts the player is stopped then he accelerates and the velocity is not constant.The horse running around the race track, same logic, different velocities.
