y: ? I need to know what goes next to the y



Write an equation for the proportional relationship. Let x represent a length measured in meters and y represent the same length measured in centimeters. I don't know what would be the equation.

Answers

Answer 1

The equation for the proportional relationship is x=y×(1/100) where x represents length in meters and y represents same length in centimeters.

What is meant by proportionality?

The phrase proportionality refers to any relationship that always has the same ratio. The quantity of apples in a crop, for example, is proportionate to the number of trees in the orchard, with the ratio of proportionality being the average number of apples per tree.

In mathematics, two sequences of numbers, generally experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is known as the coefficient of proportionality or proportionality constant.

Given,

Length(cm): Length(m)

    100         :   1

    250         :  2.5

     78.2        :   782

     123.9       :  1.239

The value that goes next to y is,

y: y×(1/100)

Therefore, x=y×(1/100)

The equation for the proportional relationship is  x=y×(1/100)

A rectangular room is

meters. Find the dimension of the room.

Answers

Answer:

Step-by-step explanation:

P = 2(L + W)

P = 34

L = W + 5

34 = 2(W + 5 + W)

34 = 2(2W + 5)

34 = 4W + 10

34 - 10 = 4W

24 = 4W

24/4 = W

6 = W <=== 6 meters wide

L = W + 5

L = 6 + 5

L = 11 <=== 11 meters long

In a raffle, 1,500 tickets are sold for $3 each. One ticket will be randomly selected and the winner will receive a laptop computer valued at $1000. What is the expected value for a person that buys one ticket?
e(x)=-2.33
how do you find that answer ?

Answers

The solution to probability problem is the expected value for a person that buys one ticket is -$2.32

What is probability?

Probability is a measure of the likelihood or chance that a specific event will occur, expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.

According to the given information:

To find the expected value, you need to multiply each possible outcome by its probability and then add them together.

In this case, there are two possible outcomes: either the person wins the laptop computer (with a probability 1/1500), or they don't win anything (with a probability 1499/1500).

So, the expected value can be calculated as:

E(x) = (1/1500)($1000) + (1499/1500)(-$3)

E(x) = $0.67 - $2.99

E(x) = -$2.32

So the expected value for a person that buys one ticket is -$2.32.

Answers

Answer: option two

Explanation: The way to solve this would be to do the equation in the parentheses then the sum of that is what you either divide or subtract to the number outside the parentheses.

For example option two: (56-42)➗7=2
The first step is to complete the equation in the parentheses, 56-42= 14
Step two is to take the sum of that (14) and divide it by seven. Which equals two

Answer:

Option 2 —› (56 - 42) / 7 = 2

Step-by-step explanation:

First you use PEMDAS to check.

P- parentheses

E- Exponents

M- Multiplication (can be switched with D)

D- Division (can be switched for M)

A- Addition

S- Subtraction

Now you need to solve each problem.

Option 1: INCORRECT

(56 - 42) / 7 = 5

(14) / 7 = 5

2 = 5

Option 2: CORRECT

(56 - 42) / 7 = 2

(14) / 7 = 2

2 / 2

I'll do the rest, so you can see how to solve.

Option 3: INCORRECT

56 - (42 / 7) = 2

56 - 6 = 2

50 = 2

Option 4: INCORRECT

(56 - 7) / 42 = 5

(49) / 42 = 5

If a polynomial f\mathopen{}\mathclose{\left(x\right)}f(x)​ has a remainder of 22​ when divided by x-6x−6​, what is f\mathopen{}\mathclose{\left(6\right)}f(6)​?\

Answers

f\mathopen{}\mathclose{\left(6\right)}f(6)​ = (6-6)(something) + 22​ = 0(something) + 22​ = 22 which has a remainder of 22 when divided by x-6x-6​. f\mathopen{}\mathclose{\left(6\right)}f(6)​ = \boxed{22}.

What is the remainder theorem?

The remainder theorem states that when a polynomial is divided by a linear term, the remainder equals the value of the polynomial at the root of the linear term. This theorem may be used to determine the roots of a polynomial by dividing it by a linear term and solving for the remainder. For instance, when the polynomial x3+x2-5x+6 is divided by (x2), the result is identical to the polynomial's value at x=2. After finding the remainder, we may determine that the polynomial's root is 2, which we can do by solving for the remainder. This theorem may also be used to discover the roots of higher degree polynomials by combining linear terms.

How to solve?

f\mathopen{}\mathclose{\left(x\right)}f(x)​ can be written as (x-6)(something) + 22​.  

f\mathopen{}\mathclose{\left(6\right)}f(6)​ = (6-6)(something) + 22​ = 0(something) + 22​ = 22​.

Therefore, f\mathopen{}\mathclose{\left(6\right)}f(6)​ = \boxed{22}.

a. What is the y-intercept of the best fit line? What does the y-intercept of the line mean in this situation? Is it reasonable?

Answers

The y-intercept of the line of best fit is -5.18cm and it is showing the initial height of the plant immediately it was planted and it is not reasonable because it shows a negative height

What is the slope of the line of best fit?

The general form of the equation of a line in slope intercept form is expressed as;

y = mx + c

where;

m is slope

c is y-intercept.

Now, we are given the equation of the line of best fit as;

y = 0.404x - 5.18

where;

y represents the height of the plant above ground level.

x represents the number of days since it was planted.

a) From the given equation, we see that the slope is; m = 0.404 and that the y intercept is -5.18.

Now, what the y-intercept means is that the height of the plant is 5.18 cm below the ground and this is not reasonable.

3x + 5y = 48
2x-y=19

y=3

x=11

hence answer 25

3x+5y=48

2x-y=19

eliminate x to find y

(2x-y=19)3

(6x + 10y. = 96)

- minus direct

(6x - 3y. = 57)

=

13y = 39

Note: (10y -(-3y)=13y)

divide by 13 to remain with y

y =3

substitute to any equation to get x lets pick second one

2x-(3)=19

2x-3=19

2x=19+3

2x/2=22/2. (to remain with x value)

x=11

therefore 2x+ y results to 2(11) +3=25

Answer:

2x + y = 25

Step-by-step explanation:

Given equations:

[tex]\begin{cases} 3x + 5y = 48\\\;\;2x-y=19\end{cases}[/tex]

Rearrange the second equation to isolate y:

[tex]\implies 2x-y=19[/tex]

[tex]\implies 2x-19=y[/tex]

Substitute the found expression for y into the first equation and solve for x:

[tex]\implies 3x+5y=48[/tex]

[tex]\implies 3x+5(2x-19)=48[/tex]

[tex]\implies 3x+10x-95=48[/tex]

[tex]\implies 13x=143[/tex]

[tex]\implies x=11[/tex]

Substitute the found value of x into the equation for y and solve for y:

[tex]\implies y=2x-19[/tex]

[tex]\implies y=2(11)-19[/tex]

[tex]\implies y=22-19[/tex]

[tex]\implies y=3[/tex]

Therefore, the solution of the given system of equations is:

x = 11,  y = 3

To find the value of 2x + y, substitute the found values of x and y into the expression and solve:

[tex]\begin{aligned}\implies 2x+y&=2(11)+3\\&=22+3\\&=25\end{aligned}[/tex]

Therefore:

That is 7 answers total.

Answers

The side lengths of the triangle are 89 ft, 132 ft and 159 ft

The angles of the triangle are 34 degrees, 56 degrees and 90 degreesThe area of the triangle is 5874 square units

The sides of the triangle

The given parameters are

Angle, A = 34 degrees

Hypotenuse = 159 ft

The length BC is calculated as

sin(A) = BC/Hypotenuse

So, we have

BC = Hypotenuse * sin(A)

This gives

BC = 159 * sin(34 degrees)

Evaluate

BC = 89 ft

The length AC is calculated as

cos(A) = AC/Hypotenuse

So, we have

AC = Hypotenuse * cos(A)

This gives

AC = 159 * cos(34 degrees)

Evaluate

AC = 132 ft

The angles for the triangle

Here, we have

Angle, A = 34 degrees

Because the triangle is a right triangle, we have

Angle, C = 90 degrees

The sum of angles in a triangle is 180

So, we have

Angle B = 180 - 90 - 34

Angle B = 56

The area of the triangle

This is calculated as

Area = 0.5 * BC * AC

So, we have

Area = 0.5 * 89 * 132

Evaluate

Area = 5874

Hence, the area is 5874 square units

now, if we run a dashed line as you see from a corner to the other to make the flatter triangle which is shaded, we end up cutting the equilateral triangle into two equal halves, each with 30° and 30° angles, because the dashed line intercepts the green line at 90°.

well, the flatter triangle from corner to corner, is spanning over two equilateral triangles, if it's owning half of one, it must be also owning half of the other.  What the dickens does that mean?  well, it means the area of the flatter triangle that's shaded, is really the same area as a "whole" of one of those equilateral triangles.
