There are 80 houses in the neighborhood 1/4 of the houses have a chain-link fence in the backyard 2/5 of the houses have a privacy fence in the backyard the rest of the houses have no fence how many houses have no fence in the backyard

Answers

Answer 1

Based on the number of houses in the neighborhood and those that have a chain-link fence and a privacy fence, the number of houses with no fence in the backyard are 28 houses

How to find the number of houses with no fence?

First, find the number of houses in the neighborhood that have a chain-link fence:

= Number of houses x Proportion with a chain-link fence

= 80 x 1/4

= 20 houses

Then find the number of houses in the neighborhood that have a privacy fence:
= Number of houses x Proportion with a privacy fence

= 80 x 2/5

= 160 / 5

= 32 houses

The number of houses in the neighborhood that have no fence is:

= Total number of houses - Houses with a chain-link fence - Houses with a privacy fence

= 80 - 20 - 32

= 28 houses with no fence

to solve the equations, substract both equations ,

Drag each object to show whether distance is proportional to time in the situation represented.

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.

The distance and time table (4 - 15, 8 - 30, 12 - 45) does not show enough information, we need to know if the initial point was of (0,0).

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 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.

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°.

Lines AB and CD are parallel. Find the measure of the three angles in triangle FAB.
136⁰

71⁰

Answers

For the given parallel lines AB and CD, the measure of the angle of the triangle ∠FAB = 25°.

What is defined as the corresponding angles?Corresponding angles are generated when two parallel lines have been intersected by a transversal.The definition of corresponding angles states that when two parallel lines intersect with a third, the angles that occupy the very same relative position at every intersection are said to be corresponding angles to one another."The two lines are considered to be parallel if indeed the corresponding angles inside the two intersection areas are congruent."

For the given question;

Line AB || Line CD

From the given diagram,

∠CFD = ∠AFB = 110 (corresponding angles)

Now, in triangle ABF

By the property of triangle; sum of all interior angles of triangle is 180.

Thus,

∠AFB + ∠ABF + ∠FAB = 180°

Put the values;

110° + 45° + ∠FAB = 180°

∠FAB = 180° - 155°

∠FAB = 25

Thus, the measure of the angle ∠FAB = 25° in triangle FAB.

In many atoms, the nucleus also contains neutrons. A neutron has no electrical charge. Determine whether each statement is true or false to complete the table. Situation: A DJ will play music. The DJ charges $20 per hour plus a $50 appearance fee. Represent the relationship between the number of hours the DJ works and the total cost of hiring the DJ. A = {Prime numbers between 10 and 16} B = {Multiples of 3 between 10 and 16} (a) List the members of AUB. (b) What is AB? (c) Is it true that 11 B? Lets imagine a ball being thrown up in the air by the wind, meaning that it started on the ground. If we were to graph how the balls height changes relative to time, we would get a parabola or a what looks like or a curve that is upside down (sort of like the smile of sad face or upside down smiley face).
