The length of the third side can be any value in the interval:
4 < x <10
What are the possible lenghts of the third side?For any triangle whose side lengths are A, B, and C, the triangular inequality says that the sum of the lengths of any two sides must be larger than the length of the other side, then:
A + B > C
A + C > B
C + B > A
Here we know that the side lengths are 3, 7 and x.
Then we can write:
3 + 7 > x
x + 3 > 7
x + 7 > 3
Solving these, we can write:
10 > x
x > 7 - 3 = 4
x > 3 - 7 = -4
Then the range of possible values of the third sides are:
4 < x <10

x=3
2+3i
Answer:
p(x) = x³ - 7x² + 25x - 39
Step-by-step explanation:
complex roots occur as conjugate pairs, thus
2 + 3i is a root then 2 - 3i is also a root
given x = 3, x = 2 +3i, x = 2 - 3i are roots, then
(x - 3), (x - (2 + 3i))(x - (2 - 3i)) are the factors and
p(x) = a(x - 3)(x - 2 - 3i)(x - 2 + 3i) ← a is a multiplier
let a = 1
p(x) = (x - 3)((x - 2)² - 9i²)
= (x - 3)(x² - 4x + 4 + 9) → [ i² = - 1 ]
= (x - 3)(x² - 4x + 13)
= x³ - 4x² + 13x - 3x² + 12x - 39
= x³ - 7x² + 25x - 39
Seamstress Jane has purchased 50 yards of red fabric and 110 yards of gold fabric to make red and gold curtains. What is the largest number of curtains she can make if she wants all the curtains to be exactly the same length, and to have no fabric left over? How many yards of each kind of fabric would be used for each curtain/?
Answer: There are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.
There are 5 red fabrics and 11 gold fabrics that would be used for each curtain.
Step-by-step explanation:
Since we have given that
Number of yards of red fabric purchased by Jane = 50
Number of yards of gold fabric purchased by Jane = 110
We need to find the largest number of curtains she can make if she wants all the curtains to be exactly the same length.
For this we will find H.C.F. of 50 and 110.
Factors of 50 = 1, 2, 5, 10, 25, 50.
Factors of 110 = 1, 2, 5, 10, 11, 22, 55, 110.
So, Highest common factor of 50 and 110 is 10.
So, there are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.
Number of yards of red fabric is given by
[tex]\frac{50}{10}=5[/tex]
Number of yards of gold fabric is given by
[tex]\frac{110}{10}=11[/tex]
Hence, there are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 500 people. By selling tickets, the members would like to raise $3050 every night to cover all expenses. Let d represent the number of adult tickets sold at $8.50. Let s represent the number of student tickets sold at $5.50 each. If all 500 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $3050? At one performance there were twotwo times as many student tickets sold as adult tickets. If there were 360 tickets sold at that performance, how much below the goal of $3050 did ticket sales fall? The members sold___ adult tickets and_____student tickets
Answer: In first question, Number of student's ticket(s) = 400
And number of adult's ticket(d) = 100
In second question, The goal of $3050 fell by $710
Step-by-step explanation:
1. Since, Here d represents the number of adult tickets and s represents the number of student tickets.
And, all 500 seats are filled for a performance.
Therefore, s + d = 500 ------(1)
Also, the price of one adult's ticket = $8.50
The price of one student's ticket= $5.50
And, their is a revenue of $3050 by selling the tickets.
Thus, 8.50 d + 5.50 s = 3050 --------(2)
By solving the equation (1) and equation (2),
we get, s = 400, d=100
Thus, Number of student's ticket(s) = 400
And number of adult's ticket(d) = 100
2. According to the question,
s = 2 d ----- (3)
s + d = 360 -----(4)
By solving equation (3) and (4),
We get, s = 240 and d = 120
thus, the total revenue after selling 360 tickets = 8.50 × 120 + 5.50 × 240 = $2340
But, the goal is $3050 ( according to the question)
Thus the total fall = 3050 - 2340 = $710
The city cultural center needs to sell 140 adult and 360 student tickets to meet their target revenue of $3050. If they sell 120 adult tickets and 240 student tickets (360 in total), they will fall $710 short of their goal.
Explanation:In order to help the members of the city cultural center determine how to distribute tickets between adults and students to meet their target revenue, we have to solve a system of linear equations. The two equations we have for the system are 8.50d + 5.50s = 3050 (which represents the relationship between the price of adult and student tickets and the targeted total revenue), and d + s = 500 (which expects all 500 seats to be filled). Solving these equations, we find that d = 140 adult tickets and s = 360 student tickets need to be sold.
For the second part of the question, they sold 120 adult tickets and 240 student tickets, making a total of 360 tickets at one performance. The total revenue generated from these tickets is (120*8.50) + (240*5.50) = 1020 + 1320 = $2340. So, they fell $3050 - $2340 = $710 below the goal.

What is the definition of similar figures
Answer:
Figures are objects that have the same shape, but may have different sizes.
Similar figures are figures that have the same shape but different sizes, with corresponding angles equal and side lengths proportional. This mathematical concept can be applied to many real-world and artistic comparisons.
The definition of similar figures in mathematics is that they are figures that have the same shape but may differ in size. This means that corresponding angles of similar figures are equal, and the lengths of corresponding sides are proportional. For example, all circles are similar to each other since they all have the same shape, regardless of their diameter. A real-world example can be seen when comparing photographs of objects that are the same shape but different sizes, such as a large elephant and a small toy elephant. Despite the size difference, if both are scaled versions of each other, they are considered similar figures.
The concept of similarity extends to various fields and contexts. In art analysis, similar figures may refer to recurring shapes or themes within artworks. An understanding of figure-ground perception, as seen in optical illusions like a vase or two faces, also plays on the concept of recognizing similar shapes within different contexts.

Eddie orders 8 pizzas for a party. He gives each person at the party 3/5 of a pizza. How many people are at the party?
Eddie ordered 8 pizzas and gave each person 3/5 of a pizza. By dividing the total amount of pizza by the amount each person gets, we determine that there are roughly 13 people at the party.
Explanation:To solve this problem, you have to divide the total amount of pizza by the amount each person gets. Eddie ordered 8 pizzas and he is giving each person 3/5 of a pizza. To find the number of people, you simply divide the total pizza by the pizza each person gets. The calculation would look like this: 8 divided by (3/5) is equal to 8 * (5/3), which is equal to 40/3, roughly 13.33.
Since we can't have a fraction of a person at the party, we would round this down to 13 people.

Im supposed to get the y intercept in this so, the line goes through the points (-1, -7) and (-8, -2) Its graphing for Algebra 1
Answer:
The y intercept is -54/7
Step-by-step explanation:
We can find the slope
m = (y2-y1)/(x2-x1)
= (-2--7)/(-8--1)
= (-2+7)/(-8+1)
=5/-7
= -5/7
We can use the point slope form of the equation to find the equation of the line
y-y1 = m(x-x1)
y--7 = -5/7 (x--1)
y+7 = -5/7 (x+1)
Distribute the -5/7
y+7 = -5/7 x - 5/7
Subtract 7 from each side
y+7-7= -5/7 x -5/7 -7
y = -5/7x -5/7 -7
Get a common denominator of 7
y = -5/7x -5/7 -49/7
y = -5/7x -54/7
This is in the form
y= mx+b, where b is the y intercept
The y intercept is -54/7

We have 3 lbs or trail mix. We need to put it in 8 bags.
Take the pounds and divide by the bags.
3 lbs / 8 bags
Each bag will have 3/8 of a pound
Answer:
Pounds / bag = 3/8 = 3/8 of a pound per bag.
Step-by-step explanation:
What you are doing is saying that the total number of bags is 8
Each bag must contain the same amount of trail mix. So your units are pounds per bag. That is a very handy thing to know. It means that pounds is the numerator and bags is the denominator.
pounds = 3bags = 8pounds / bag = 3/8 Conclusion: each bag contains 3/8 pounds.Answer B

"The greatest number of flash cards that Juan can cut out of the piece of cardboard is 12.
To determine the greatest number of flash cards that Juan can cut out of the cardboard, we need to calculate the area of the cardboard and divide it by the area of one flash card.
Let's denote the dimensions of the cardboard as [tex]\( L \) inches by \( W \)[/tex] inches, and the dimensions of each flash card as [tex]\( l \)[/tex]nches by [tex]\( w \)[/tex] inches. Given that the cardboard is[tex]\( L \times W \)[/tex]inches and each flash card is [tex]\( l \times w \)[/tex]inches, we can calculate the number of flash cards as follows:
1. Calculate the area of the cardboard: [tex]\( \text{Area}_{\text{cardboard}} = L \times W \).[/tex]

A) a rotation of 270° counter clockwise about the origin followed by translation of eight units to the right
B) A reflection over the Y axis followed by a rotation of 180° about the origin
C) a dilation with a scale factor of four followed by reflection over the x-axis
D) A reflection over the Y axis followed by a translation of 3 units to the left and 2 units to the right
Answer:
The correct option is C.
Step-by-step explanation:
Two figures are congruent if their corresponding sides are congruent.
We know that, reflection, rotation and translation are rigid transformation. It means the size and shape of image and preimage are same. We can say that in rigid transformation, the image and preimage are congruent.
Dilation is not a rigid transformation. It represents enlargement and compression.
If scale factor |k|>1, then it represent enlargement. If scale factor |k|<1, then it represent compression.
In option C, the scale factor is 4. It means the sides of image are 4 times of the preimage.
Therefore option C is correct and the resultant figure of option C is not congruent to the original figure.

Wangari plants trees at a constant rate of 12 trees every 3 hours. Write a equation that relates p, the number of trees Wangari plants, and h, the time she spends planting them in hours.
Wangari plants trees at a rate of 4 trees per hour. The equation relating the number of trees planted (p) to the time spent planting (h) is p = 4h.
Equation for Trees Planted by Wangari
Wangari plants trees at a constant rate, which means we can write a linear relationship between the number of trees planted (p) and the time spent planting them (h in hours). From the problem, we know:12 trees are planted in 3 hoursFirst, let's find the rate of planting trees per hour. We do this by dividing the number of trees by the number of hours:Rate = Number of Trees / TimeRate = 12 trees / 3 hours = 4 trees/hourThis tells us that Wangari plants 4 trees every hour. To write an equation that relates the number of trees (p) to the number of hours (h), we use the rate we found:
p = 4hHere, p represents the number of trees planted and h represents the number of hours spent planting.
