6. Definition of isosceles triangle

Answer 2

Triangle ABC Is an isosceles triangle because line AB is equal to line AC .

What is an isosceles triangle?

An isosceles triangle is a triangle with two equal sides and two equal angles. The third side and angle may differ in length and measure.

The symmetry in side lengths and angles gives it distinct geometric properties.

Since line BD is equal to line CE and line CE is equal to line AC, this means that line BC is a bisector of line AD and AE,

Therefore we can say triangle ABC is an isosceles triangle because AB = AC.

The total daily cost (in dollars) of manufacturing scented candles is given by the function C(b) = 250 + 3b, where b is the number of candles manufactured. Which function represents the average manufacturing cost, A, in terms of b?

Answers

Final answer:

The average total cost of manufacturing scented candles is given by the formula A(b) = C(b)/b = (250 + 3b)/b, where b is the number of candles manufactured.

Explanation:

The concept of average total cost is key in the calculation. Given the function for total cost of the candles, C(b) = 250 + 3b, the average cost, A, can be calculated by dividing the total cost by the number of candles, b. Therefore, the function representing the average cost, A, in terms of b is given by A(b) = C(b)/b = (250 + 3b)/b. It's important to note that this function also signifies the 'economies of scale', stating as output number increases, the average cost falls.

There are 3 blue marbles, 8 red marbles, 4 green marbles and 5 yellow marbles. What number represents 50% of the marbles?

Answers

10 marbles represent 50% of the marbles. To get this, turn the percent into a decimal. 50% equals 0.50. You the multiply the total amount of marbles (20) by the decimal, equaling 10 marbles.
The answer is 10.

Because you need the number that represents 50% of all the marbles. so you have to add them all up:

3+8+4+5=20

50% means half, which means you have to divide the total by 2.

20÷2=10

Cx x ( ) = + 8 50 represents the cost C (in dollars) of
towing a vehicle, where x is the number of miles the
vehicle is towed. Identify the slope and y-intercep

Answers

Final answer:

The slope of the linear equation C(x) = 8x + 50 is 8, indicating an $8 charge per mile, and the y-intercept is 50, the flat towing fee. Similar service-based costs from other examples also follow this linear model, with their unique slopes and y-intercepts corresponding to the per-hour or per-mile charges and flat fees.

Explanation:

The function C(x) = 8x + 50 represents the cost of towing a vehicle, where C is the cost in dollars, and x is the number of miles the vehicle is towed. The slope of this line is 8, which indicates that the cost increases by $8 for every mile the vehicle is towed. The y-intercept is 50, representing the flat fee charged regardless of the distance towed, which is the cost when x (the number of miles) is 0.

Relating to the other examples provided, we can see a pattern in how these equations are structured for service-based costs. For instance, in Aaron's Word Processing Service, the total cost equation is y = 32x + 31.50, where the slope is 32 representing the hourly charge, and the y-intercept is 31.50, the fixed cost. Similarly, for Ethan's household appliance repairs, the equation is y = 20x + 25, with a slope of 20 and a y-intercept of 25. All these models illustrate how fixed fees and variable rates per service hour or mile can be represented in a linear equation format.

3. A local band had a concert and made $1,824 from ticket sales. If each ticket cost $16, how many tickets did the band sell? (Write and solve an equation.)

What are you trying to find?


What is the important information?

Write the equation below. What does the variable represent?

Solve and show work below.

Answers

First take not of the total sales and the cost of each ticket.

1,824 and 16

Now setup the equation

16x=1824

To solve this divide 1824 by 16 getting

X=144

x is the total tickets sold

Each ticket (t) costs $16. The band made a total of $1,824 from ticket sales, meaning that 16t=1,824, because the total amount of 16 dollar tickets sold is equal to the total made from ticket sales.

The equation is:

16t=1,824.

You are trying to find the amount of tickets sold by solving the equation.

t stands for the total amount of tickets sold.

Solving the equation:

16t=1,824

Divide both sides by 16.

t=114

114 tickets were sold. 114*16=1,824. This means that when 114 $16 tickets were sold, the band did make $1,824, which shows that 114 is the correct answer.

I hope this helps :)

A car drives at a speed of 90km/h for 2 hours and 20 mins how far does the car travel

Answers

2 hours and 20 minutes is 2 and a third hours. Multiply 90 by 2 and a third.


90 × 2.333
209.999

If you round to the nearest kilometer, the answer is 210 km

Final answer:

The car travels approximately 210 kilometers in 2 hours and 20 minutes by multiplying its speed of 90km/h by the time duration converted to hours (2.333 hours).

Explanation:

The student's question involves calculating the distance a car travels at a constant speed over a given period of time. In this case, the car drives at a speed of 90km/h for 2 hours and 20 mins. To find the distance, you can use the formula: distance = speed × time. First, convert 2 hours and 20 mins into hours, which is 2 hours + 20/60 hours = 2.333 hours.

Next, multiply the speed by the time to get the distance:

Distance = 90km/h × 2.333 hours = 209.97 km

So, the car travels approximately 210 kilometers in 2 hours and 20 minutes.

A group of 485 people take a canoe trip. They fill up all avalible canoes that each hold 3 people with 273 people. The rest of the group will ride in canoes
that each hold 2 people. How many canoes will the group need? Write equations with unknown to show your steps.

Answers

Answer:
3c=273
c=91
2c= 212
C= 106
c= 91+ 106= 197
so they will need 197 canoes total

Why:
So first you have to determine a set variable to represent the number of canoes, I chose C. Then you make an equation to represent the number of canoes 273 people will use if they group into 3's, from this I got 3c=273. Solve for C and get 91.
The remainder of the group which is 485-273= 212 will use canoes in groups of 2's. To represent this, 2c=212. Solve for C and get 106. Combine 106 and 91 to get the total number of canoes.

Answer:

They will need 197 canoes.

Step-by-step explanation:

The first step is to find the ''3-people canoes'' that they filled.

Given that 273 people filled a certain number ''a'' of canoes that each hold 3 people, we know that is we multiply the number of canoes ''a'' by the number of people that can each canoe hold, we will obtain the number of people who

will take the canoe trip in the ''3-people canoes''. We write :

[tex]3a=273[/tex] ⇒

[tex]a=\frac{273}{3}=91[/tex]

We find that [tex]a=91[/tex] canoes. This means that 91 ''3-people canoes'' were filled each one with 3 people in order to hold 273 people in total.

The second step is to find the remaining people that won't take the ''3-people canoes''. We do this by subtracting 273 people to the total 485 people.

[tex]485-273=212[/tex]

We know that 212 people will travel in the ''2-people canoes''. Using a similar reasoning and defining as ''b'' to the total number of ''2-people canoes'' we write :

[tex]2b=212\\b=\frac{212}{2}=106\\ b=106[/tex]

We find that [tex]b=106[/tex] canoes is the total number of ''2-people canoes'' that we need If we want them to be filled up with 212 people.

The total number of canoes that the group will need is the sum of ''3-people canoes'' and ''2-people canoes'' :

[tex]Total=a+b=91+106=197[/tex]

The group of 485 people will need 197 canoes.

The measure of an angle is fifty-nine times the measure of a supplementary angle.What is the measure of each angle?

Answers

3° and 177°

x = [tex]\frac{180}{60}[/tex] = 3

the angles are 3° and (59 × 3 )= 177°


Final answer:

To find the measures of two supplementary angles where one is fifty-nine times larger than the other, set up an equation x + 59x = 180, and solve for x. The smaller angle is 3 degrees, and the larger angle is 177 degrees.

Explanation:

The measure of an angle is fifty-nine times the measure of a supplementary angle. To solve this, we can set up an equation where x is the measure of the smaller angle, and therefore, 59x is the measure of the larger angle. Since angles are supplementary, their sum is 180 degrees. So, our equation is x + 59x = 180. Solving for x, we find that x = 3 degrees and 59x = 177 degrees.

Let

We shall apply the remainder theorem to obtain the remainder when
[tex]p(x)[/tex]
is divided by
[tex]x + 5[/tex]

According to the remainder theorem, if a polynomial
[tex]p(x)[/tex]

[tex]x - a[/tex]
then the remainder is
[tex]p(a)[/tex]


So we set
[tex]x + 5 = 0[/tex]

and solve for
[tex]x[/tex]

to obtain,

[tex]x = - 5[/tex]


We now substitute -5 into the given polynomial to find the remainder.



[tex]p( - 5) = 5 {( - 5)}^{2} + 10( - 5) - 15[/tex]


This gives us,

[tex]p( - 5) = 5(25) - 50 - 15[/tex]

This will simplify to,
