Which set represents line segments that could be connected to form a triangle:

A. (1, 2, 3)
B. (3, 4, 5)
C. (1, 10, 100)

E. (1, 3, 4)
F. (1, 20, 100)

Please don't just give a letter choice as an answer. There are more questions like this one and I'd like to understand how to do it : )

Answers

Answer 1

Answer:

  B: (3, 4, 5)

Step-by-step explanation:

You want to know which segment lengths could be used to form a triangle.

Triangle inequality

The triangle inequality requires the sum of the two short sides of a triangle exceed the length of the longest side.

A: 1+2 = 3 . . . not a triangle

B: 3+4 > 5 . . . forms a triangle

C: 1+10 < 100 . . . not a triangle

D: 1+2 < 5 . . . not a triangle

E: 1+3 = 4 . . . not a triangle

F: 1+20 < 100 . . . not a triangle

__

Additional comment

The above expression of the triangle inequality seems to be the one most commonly used in algebra and geometry courses.

The triangle inequality can also be seen to be expressed as ...

  a + b ≥ c . . . . . . where a, b, c are side lengths in any order

The "equal to" case allows triangles of zero height. (They look like a line segment.) Using that formulation, triples A and E in your answer list will also be considered to form a "triangle."

Dalia's living room is 12 feet long and 10 feet wide. Her dining room
is also 10 feet wide. Write two equivalent expressions that each
represent the combined area of the two rooms.
10ft

Room
xft-

Answers

(120 + 10x) sq. feet or 10(12+x) sq. feet will be the combined area of the two rooms.

the given dimensions of the living room are given as follows,

length =12

width/breadth =10

thus the area of the living room will be,

length x breadth, i.e.

=12 x 10

=120 sq. feet

the given dimensions of the dining room are given as follows,

length= x

width/breadth=10

thus the area of the dining room can be calculated as

length x breadth

=10x sq. feet

Now, to calculate the combined area of both the rooms, we have to add the area of the dining room and the area of the living room,

that is,

(120 + 10x) sq. feet

The elephants at the zoo eat 3 1/6 buckets of bananas each day. The zookeeper bought 6 1/3 buckets of bananas. How many days will the bananas last?

Write your answer as a fraction or as a whole or mixed number.

Answers

The bananas will last 2 days at the zoo (found by division).

According to the question,

We have the following information:

The elephants at the zoo eat [tex]3\frac{1}{6}[/tex] buckets of bananas each day. The zookeeper bought [tex]6\frac{1}{3}[/tex] buckets of bananas.

Now, first we will find the number of days taken in eating 1 bucket of bananas.

[tex]3\frac{1}{6}[/tex] buckets = 1 day

Now, we will convert this mixed fraction into simple fraction.

19/6 buckets = 1 day

1 bucket = 1/(19/6) days

1 bucket = 6/19 days

Now, we have the total number of buckets as [tex]6\frac{1}{3}[/tex].

Now, after converting this mixed fraction, we have:

19/3 buckets

1 bucket =  6/19 days

19/3 buckets = (6/19)*(19/3)

19/3 buckets = 2 days

2 is a whole number.

Hence, the given buckets of bananas will last 2 days.

Area of a Sector

The formula for the b of the sector of a circle is /360o (r2) where r is the radius of the circle and  is the angle of the sector.

Area of a Sector of Circle = (θ/360º) × πr^2, where, θ is the sector angle subtended by the arc at the center, in degrees, and 'r' is the radius of the circle.

Data;

Radius - 8cmangle = 56 degrees

Answers

Answer:

Part A: C(x) = 0.068x+0.8

Part B: 1.28

Part C: 9.76

Explanation:

Part A:

The cost C equals

cost = revenue - profit

[tex]C(x)=R(x)-P(x)[/tex]

which is

[tex]C(x)=0.15x-(0.082x-0.8)[/tex][tex]C(x)=0.15x-0.082x+0.8[/tex][tex]\boxed{C\mleft(x\mright)=0.068x+0.8}[/tex]

Part B:

The cost of producing 7 units is found by putting in x = 7 into the above equation. This gives

[tex]C(7)=0.068(7)+0.8[/tex][tex]C(7)=1.28[/tex]

Hence, the cost of producing 7 items is 1,28 million dollars.

Part C:

To break even, the cost must equal the revenue

[tex]R(x)=C(x)[/tex]

or

[tex]0.15x=0.068x+0.8[/tex]

subtracting 0.068 from both sides gives

Given the two sides measurement,

• Assuming that the other side represent x and the other side represent y,( 4cm;6cm) , and that we are drawing a right angle triangle .We can constuct a triangle as follows :

• We can find the value of side h by using Pythagorean theorem:

[tex]\begin{gathered} \text{ h = }\sqrt[]{x^2+y^2}\text{ } \\ \text{where x = 4}cm\text{ and y = 6}cm\text{ , } \\ \therefore\text{ h = }\sqrt[]{4^2+6^2} \\ \text{ = 7.2 }cm \end{gathered}[/tex]

Miss sheet,owner of the Bedspread shop knows his customers will pay no more than $145 for a comforter Misu wants a 40percent markup on selling price what is most that Misu can pay for a comforter?

Answers

The price that Misu can pay for a comforter based on the markup percentage is $103.57.

How to calculate the value?

From the information, the Bedspread shop knows his customers will pay no more than $145 for a comforter Misu wants a 40 percent markup on selling price.

Let the selling price be represented as x. Based on the information given, this will be illustrated as:

x + (40% × x) = 145

x + 0.4x = 145

1.4x = 145

Divide

x = 145/1.4.

x = 103.57

The selling price will be $103.57.

What is an equation of the line that passes through the point (8,0)(8,0) and is parallel to the line x-4y=20x−4y=20?

Answers

The equation of the line that passes through the point (8, 0) is parallel to the line x - 4y = 20 is 1/4x - y = 2

Given,

The equation of the line: x - 4y = 20

The points which the line passes through, (x₁, y₁) = (8, 0)

We have to find the equation of the line parallel to the given line.

The formula for the slope intercept form:

(y - y₁) = m(x - x₁)

m is the slope of the line.

Lets find the slope of the line given.

x - 4y = 20

x = 20 + 4y

x - 20 = 4y

y = (x - 20) / 4

y = 1/4x - 5

Here, slope of the line is 1/4

Now, substitute the slope of the line and (x₁, y₁) in the slope intercept formula to get the equation of line parallel to the given line

(y - y₁) = m(x - x₁)

(y - 0) = 1/4(x - 8)

y = 1/4x - 8/4

y = 1/4x - 2

1/4x - y = 2

The equation of the line that passes through the point (8, 0) is parallel to the line x - 4y = 20 is 1/4x - y = 2

When we have a function and want to evalueate it for some "x", we just substitute every "x" with the value in parenthesis. So, to evaluate f(a + 2), we have x = a + 2, so we need to substitute every "x" in the function with a + 2:

Now, to simplify, we first need to use the distributive property on the second parenthesis and evaluate the binomial in the first:
