True or False: Segment Y M is congruent to segment PW. GT Y BM PD W -10 -5 0 5 10 Select one: O True O False​

Answers

Answer:

[tex]\huge\boxed{\mathrm{False}}[/tex]

Step-by-step explanation:

Length of YM = 1 - (-6)   [This is it's endpoints]

YM = 1 + 7

YM = 8

Length of PW = 9 - 5    [Subtraction of endpoints to get the length]

PW = 4

So, Segment YM is not congruent to segment PW.

Step-by-step explanation:

Point T is on line segment \overline{SU} SU . Given SU=4x+1,SU=4x+1, TU=3x,TU=3x, and ST=3x-1,ST=3x−1, determine the numerical length of \overline{SU}. SU

Answers

Answer:

The numerical length of SU =

5 units

Step-by-step explanation:

Here, we want to get the length of point SU

mathematically;

SU = ST + TU

4x + 1 = 3x -1 + 3x

4x + 1 = 6x - 1

6x-4x = 1 + 1

2x = 2

x =2/2 = 1

But SU = 4x + 1 = 4(1) + 1 = 5 units

wallpaper is sold in rolls that are 2 feet wide what is the minimum length you would need to purchase to cover the wall and 60 feet covers the wall

Answers

Answer:

28feet

Step-by-step explanation:

Let the wallpaper be a rectangle

Area of a rectangle = Length * Width

A = LW

Perimeter P = 2L+2W

If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.

60 = 2L + 2(2)

60 = 2L + 4

2L = 60-4

2L = 56

L = 56/2

L = 28

The minimum length that will be purchased to cover the wall is 28 feet

What is the mean of the data set (3, 2, 2, 12, 6, 5, 14, 4]? O 2 O 4 O 6 O 7​

Answers

Answer: 6

Step-by-step explanation:

{3, 2, 2, 12, 6, 5, 14, 4}

To find the mean,add everything up, the divide it by how many numbers you added up.

So, do :

3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48

Then, because you added 8 numbers together, you would divide 8 from 48.

48 ÷ 8 = 6

So, your mean is  6

The tables show linear functions representing the cost per hour to rent a bicycle and the cost per hour to rent in-line skates. Bicycle per Hour In-Line Skates per Hour Which function has the greater slope and what does it represent? The in-line skate function has the greater slope, which shows that the cost per hour is greater than that of the bicycles The in-line skate function has the greater slope, which shows that the cost per hour is less than that of the bicycles. The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates. The bicycle function has the greater slope, which shows that the cost per hour is less than that of the in-line skates.

Answers

Answer:the bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Step-by-step explanation:

The function has the greater slope and it represent : The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

What are linear functions?

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

What is slope?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

According to the question

The cost per hour to rent a bicycle and the cost per hour to rent in-line skates are given .

We will conclude which function has the greater slopes

if any function have greater slope than other that implies that  it have greater change in  y  axis in comparison to other

as over here  

y axis = cost

x axis = hours

Therefore,

The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

Hence, The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates

how to expand a using the distributive law

Answers

Answer:

2x(3x+5)+1(3x+5)

Step-by-step explanation:

The distributive law is the law that states that multiplying a number by a group of numbers is the same as doing each multiplication separately. Eg. A(B+C) =AB+AC

In the case of two sets of parenthesis it would look like:

2x(3x+5)+1(3x+5)

Which would give us:

6x^2 +10x +3x+5

6x^2+13x+5

The general format for 2 bracket ones would be:

(A+B) (C+D) =A(C+D) +B(C+D)

where the two terms in the first bracket go outside the second bracket twice individually because each term must be multiplied by all terms in the other bracket.

Libby donated​ $50 during the first month of the year. If she makes three additional donations of equal amounts during the​ year, how much will she need to donate each time to be in the Silver​ category?

Answers

Answer:

She will donate P-50/3 each time

Step-by-step explanation:

Now assuming total donation needed to be in the silver category Is P

We can assume also the three additional and equal donations be Q

So

Then 50 + 3Q = P

So we still don't know P

We can get Q by saying

3Q= P - 50

Q = (P - 50) /3

Which would be the best name for a function that takes the time of day and returns the numbers of coffee sold at a coffee shop? Answer choices: Coffee(time) Time(coffee) Day(time) Time(shops)

Answers

Answer:

Coffee(time)

Step-by-step explanation:

A function's output variable will be:

output(input)

So we need to find the input variable and the output variable.

We know that when the time of day changes, we get a certain amount of coffee sold. This means that the amount of coffee sold is directly influenced by the time of day.

The time of day then becomes our input as the coffee sold relies on that number.

That leaves coffee sold as our output!

So the best name for a function in this scenario is Coffee(time).
