where RS=3y+3=2y+8 and RT=31 what is the value of y

Answers

The value of y in the line segment is 4

How to find the variable in a line segment ?

RT is the total line segment.

Therefore,

RS = 3y + 3

ST = 2y + 8

RT = 31

Hence,

RT = RS + ST

31 = 3y + 3 + 2y + 8

31 = 3y + 2y + 3 + 8

31 = 5y + 11

31 - 11 = 5y

20 = 5y

divide both sides by 5

20 / 5 = 5y / 5

y = 4

To find the midpoint of the line segment joining the pair of points

S(6√3, 4,4√2) and T(4√3, 5, √2)

Midpoint:

The coordinates of the midpoint of a line segment are the average of the coordinates of the end points.

m = (A +B)/2

If we are given three points and we wish to find the midpoint of those points, we need to use the midpoint formula m =(  [tex]\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} , \frac{z_{1} +z_{2} }{2}[/tex] )

where:

(x1 , y1 ,z1) are the coordinates of the first point:

(x2 , y2 , z2) are the coordinates of the second point:

Now, We are given the three points S(6√3, 4,4√2) and T(4√3, 5, √2)

Solving for the midpoint , we have,

m = ([tex]\frac{6\sqrt{3}+4\sqrt{3} }{2} ,\frac{4+5}{2} , \frac{4\sqrt{2}+5\sqrt{2} }{2}[/tex])

m = ([tex]\frac{10\sqrt{3} }{2} , \frac{9}{2} , \frac{9\sqrt{2} }{2}[/tex] )

Find x and the measure of each side.
Δ F G H is an equilateral triangle with F G=3 x-10, G H=2 x+5 , and H F=x+20 .

Answers

For given equilateral triangle ΔFGH, x = 15. And the measure of each side is 35 units.

In given question,

ΔFGH is equilateral triangle.

The sides of ΔFGH are:

FG = 3x - 10,  

GH =2x + 5 ,

and HF = x + 20 .

We need to find the value of x.

Since ΔFGH is an equilateral triangle, FG = GH = FH

⇒  3x - 10 = 2x + 5 = x + 20

Consider  3x - 10 = 2x + 5

⇒ 3x - 2x = 5 + 10

⇒ x = 15

Now we find the measure of each side.

FG = 3x - 10

FG = 3(15) - 10

FG = 35 units

But FG = GH = FH

So, the measure of each side is 35 units.

Therefore, for given equilateral triangle ΔFGH, x = 15. And the measure of each side is 35 units.

Answers

The ratio of the number of white shoes to the number of black

shoes Alex owns is 2:3

Let the number of red shoes be x

Then from the given information, we know that

brown shoes = 3 times red shoes = 3x

black shoes = 2 times brown shoes = 2(3x)= 6x

white shoes = 4times  red shoes = 4x

We need to find the ratio between the number of white shoes and the number of black shoes owned by Alex

shoes he owns is number of white shoes : number of black shoes

Answer:

x = 3

Step-by-step explanation:

We need to find to numbers that sum up to make -6 but their product is +9 :

-3 and -3 will do :

Now we split -6x into -3x and -3x :

x² -3x -3x + 9 = 0  

Factorise the first 2 terms:

x(x-3)

Keeping the terms inside the bracket the same as the 1st one factorise the next 2 terms :

x(x-3)-3(x-3) = 0

Keep 1 bracket and make another bracket out of the terms that are outside the brackets :

(x-3)(x-3) = 0

Using the integer rule :

a × 0 = 0

We know that one of these brackets are equal to zero :

x-3= 0

Add 3 to both sides :

x = 3

The other bracket is the same so our final answer is x = 3

Mary's coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs mary $5.35 per pound, and type b coffee costs $4.15 per pound. this month, mary made 181 pounds of the blend, for a total cost of $853.15. how many pounds of type b coffee did she use?

Answers

Mary used 96 pounds of type b coffee this month.

Using algebraic expression and equation, we can solve how much of each type of coffee did Mary used that month.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

Given that that month, Mary made 181 pounds of the blend that is a mixture of two types of coffee, we can express this as:

181 = a + b

where a = pounds of type a coffee that costs $5.35 per pound

b = pounds of type b coffee that costs $4.15 per pound

Also, the total cost of the blend that month is $853.15, which is the sum of the total cost of the two types of coffee. We can express that as:

$853.15 = $5.35(a) + $4.15(b)

Using substitution method to solve the two equations,

181 = a + b   ⇒   a = 181 - b

$853.15 = $5.35(181 - b) + $4.15(b)

853.15 = 968.35 - 5.35b + 4.15b

5.35b - 4.15b = 968.35 - 853.15

1.2b = 115.2

b = 96

a = 181 - b

a = 181 - 96

a = 85

Hence, Mary used 85 pounds of type a coffee and 96 pounds of type b coffee that month.

Tammy is standing on a dock beside a lake. She drops a rock from her hand into the lake. After the rock hits the surface of the lake, the rock’s distance from the lake’s surface changes at a rate of -5 inches per second. If Tammy holds her hand 5 feet above the lake’s surface, how far from Tammy’s hand is the rock 4 seconds after it hits the surface?

Answers

Lisa's hand is located twenty-five feet distant from the rock.

This is further explained below.

How far from Tammy’s hand is the rock 4 seconds after it hits the surface?

Generally, If the rock is falling at a rate of 5 inches per second, then you can easily calculate how deep below the surface of the lake it was after 5 seconds by multiplying 5 by 4.

After four seconds, the rock will have dropped -20 inches.

Because Lisa's hand is five feet above the water's surface, we need to add five to the distance between her hand and the rock in order to calculate how far away it is.

After four seconds, Lisa's hand is located twenty-five feet distant from the rock.

Find the slope of the line that passes through the two points. (4,5) and (1,8)

Answers

The slope between the two given points (4,5) as well as (1,8) is -1.

What exactly is the slope of a line?

A line's slope is a measure of its steepness & direction.

The slope of a line is defined as a change in y coordinate in relation to a change in x coordinate.

The net change in y coordinates is Δy, while the net change in x coordinates is Δx.As a result, the y coordinate change in relation to the x coordinate change could be composed as,

        m = Δy/Δx

        where,m is the slope

Slope is also written as tan θ = Δy/Δx. Where, tanθ is also called as the line's slope.

Now, as per the stated question;

The slope of a line can be calculated using only two points on a straight line. With the coordinates of two points, we can employ the slope of line formula.

Let the coordinates of those 2 points from where the line is passing is;

P1 = (x₁, y₁)

P2 = (x₂, y₂)

The slope of the  line is estimated as;

Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)

The values of the coordinates are given as;

(x₁, y₁) = (4,5) and,

(x₂, y₂) = (1,8)

Substitute the given values of coordinates in the formula to get the slope;

m = (8 - 5)/(1 - 4)

m = 3/(-3)

m = -1

Therefore, given the coordinates of such two points, the slope of a line passing through them is found to be -1.

The linear equation that describes the amount of data you can use in terms of the amount of money that you are willing to spend is q= (p-500)/3

P=3q + 500 is a linear equation where p is the price of the cellular plan and q is the amount of data used in the form of GB

In order to form a linear equation that describes the amount of data you can use in terms of the amount of money that you are willing to spend, we just need to shuffle the linear equation in order to get the coefficient if q as 1

First step, we need to move 500 from right hand side to left hand side which would change the sign from + to -.

=p - 500 = 3q

Second step, we need to move 3 from right hand side to left hand side which would change the sign from × to ÷.
