The Triangle Inequality Theorem is applied to determine the range of values for x that would make the side lengths given form a valid triangle.
Explanation:
Understanding the Triangle Inequality Theorem
The Triangle Inequality Theorem states that in any triangle, the length of any side must be less than the sum of the other two sides. For the given question, we need to use this principle to analyze the side lengths. With the two shorter sides given as [tex]\( \frac{3}{10} \) and \( x + \frac{1}{5} \)[/tex], and the longest side given as [tex]\( \frac{3}{2}x \)[/tex], we can establish the inequality:
[tex]\( \frac{3}{2}x < \frac{3}{10} + \left( x + \frac{1}{5} \right) \).[/tex]
By solving this inequality, we can find the range of possible values for x that makes the configuration a valid triangle. This problem is an application of basic geometric principles and inequalities.

you make dog collars and anticipate selling all of them at a craft fair you spent $85 for materials and hope to make a $90 profit how much should you charge for each collar
To cover costs and achieve a $90 profit, each collar should be sold for $175 divided by the number made.
To determine the selling price for each dog collar, we need to consider both the cost of materials and the desired profit.
1. **Calculate total cost**:
- Cost of materials: $85
- Desired profit: $90
Total cost = Cost of materials + Desired profit
= $85 + $90
= $175
2. **Determine number of collars**:
Since you anticipate selling all the collars, the total profit should cover the cost of materials and the desired profit.
3. **Calculate selling price per collar**:
Divide the total cost by the number of collars to determine the selling price for each collar.
[tex]\[ \text{Selling price per collar} = \frac{\text{Total cost}}{\text{Number of collars}} \][/tex]
Substitute the values:
[tex]\[ \text{Selling price per collar} = \frac{\$175}{\text{Number of collars}} \][/tex]
Without knowing the exact number of collars, we can't determine the exact selling price per collar. However, if you know the number of collars you're making, you can use this formula to find the selling price for each collar.
A flying disc has a diameter of 9 inches. What is the circumference of the disc in inches? Round to the nearest tenth.
formula= 2(3.14)r
2(3.14)4.5
2(14.13)
28.26
A flying disc is assumed to be in the shape of a circle. Since we know it is in the shape of a circle, we can use the formula for circumference of a circle.
The formula for circumference of a circle is d * pi, where d represents the diameter of the circle and pi is the representation of 3.14.
Finding the circumference.You can find the circumference of a circle by multiplying the diameter by pi, and since the question gives us the diameter of the flying disc we can substitute in 9 inches for the diameter to solve for the circumference.
diameter * pi
(9 inches) * ([tex]\pi[/tex]) = 28.2743...
Answer to the question.The question wants the final answer to be rounded to the nearest tenth, so rounding 28.2743... to the nearest tenth would make it into 28.27.
The answer to this problem is the circumference of the disc is 28.27 inches.

Enter the number that belongs in the green box.
The number that belongs in the green box is 2.
Explanation:Based on the information provided, which relates to probability and the use of a calculator, we can assume the question pertains to Mathematics, likely within a Middle School curriculum where basic probability and calculator skills are taught.
When dealing with shuffled cards or marbles in a bag, one typically calculates probabilities or expected outcomes
There are a total of eight cards: five green cards and three yellow cards.
Since the cards are well shuffled, the probability of drawing a green card is 5/8.
The probability of drawing a yellow card, in this case, would be 3/8.
Since the green cards are marked with the numbers 1, 2, 3, and 4, the number that belongs in the green box would be 2.
Final answer:
To find the number in the green box, calculate the ratio of green cards to total cards.
Explanation:
The number that belongs in the green box can be found by calculating the ratio of green cards to total cards. In this case, there are 5 green cards out of 8 total cards. To find the number that belongs in the green box, we can use the formula:
Number in green box = green cards / total cards
Number in green box = 5 / 8
Using a calculator or simplifying the fraction, we find that the number in the green box is 5/8 or approximately 0.625.

Hey can anyone help me? I just need help with the bottom table.
The question asks how many hours each person worked, and how much they earned, or basically they're asking for the right two columns to be filled in. (Total hours = how many hours each person worked, and Total pay = how much they earned)
Now let's recall the information which is given.If we look at the table, we can see we're given information for each person, Sue, Bob, and Chris. We're given their rate per hour, and the numbers of hour they worked for each day.
Now that we've looked at that, we can connect the information we're given and what the question is asking.The two things we are looking to calculate can correspond with a part of information we're given:
Total Hours <-> hours worked each day: we can see these connect as the total hours work (I'm assuming) are weekly, and to calculate the total hours worked we can look the hours worked for each day as days make up weeks. Therefore, if you just add the number of hours worked on Monday, Tuesday, Wednesday, Thursday, and Friday together, you get the total hours worked in the week.Total Pay <-> rate per hour and total hours: the total amount of pay can be calculated once we know the rate per hour and the total hours. The rate per hour is based off of the hours, it's how much is earned every hour, and the total hours include the total amount of hours worked. Therefore, if you multiply the two together you'll get the total pay. (Multiplying is essentially adding a number, another number of times, in this case it's adding the pay rate, the total hours amount of times.)Now that we know how they're connected, and therefore how to solve the equation, we can complete the calculations.Find the total hours worked for each person:
Sue: Monday: 3.5 hours, Tuesday: 10.5 hours, Wednesday: 5.25 hours, Thursday: 6 hours, Friday: 12 hours. 3.5 + 10.5 + 5.25 + 6 + 12 = 37.25 total hours workedBob: Monday: 5 hours, Tuesday: 3.5 hours, Wednesday: 7.75 hours, Thursday: 5.5 hours, Friday: 10.25 hours. 5 + 3.5 + 7.75 + 5.5 + 10.25 = 32 hours total workedChris: Monday: 6.5 hours, Tuesday: 7.25 hours, Wednesday: 9.5 hours, Thursday: 3.5 hours, Friday: 3.5 hours. 6.5 + 7.25 + 9.5 + 3.5 + 3.5 = 30.25 hours totalWe have now calculated the total hours for each person. You can therefore fill in the column of total hours, starting from the top, with 37.25 hours, then 32 hours, and finally 30.25 hours.
The final step is to calculate the total pay for each person.As I stated earlier, the only thing needed to do to find the total pay is to multiply the total hours my the rate per hour.
Sue: $16.50 per hour, 37.25 hours. 16.50 * 37.25 = $614.625, rounds up to $614.623Bob: $11.25 per hour, 32 hours. 11.25 * 32 = $360 dollarsChris: $14.50 per hour, 30.25 hours. 14.5 * 30.25 = 438.625, rounds up to $438.63Now we have all our solutions. For the total hours column, top to bottom: 37.25 hours, 32 hours, 30.25 hours. For the total pay column, top to bottom: $614.623, $360, $438.63Hope this helped!Distribute and simplify the radicals below

what is the y intercept of -10x -1/2 y = 5 ?
y-intercept is when x = 0 or the b-value when in the form y = mx + b
-10x - [tex]\frac{1}{2}y[/tex] = 5
-10(0) - [tex]\frac{1}{2}y[/tex] = 5
[tex]\frac{-1}{2}y[/tex] = 5
[tex]-2(\frac{-1}{2}y)[/tex] = -2(5)
y = -10
Answer: (0, -10)
-10x - [tex]\frac{1}{2}y[/tex] = 5
+10x +10x
[tex]\frac{-1}{2}y[/tex] = 10x + 5
[tex]-2(\frac{-1}{2}y)[/tex] = -2(10x + 5)

(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2

two cars traveled equal distances in different amounts of time. car A traveled the distance in 2 hours , and car B traveled the distance in 1.5 hours. car B traveled 15 mph faster than car be what is the speed of car B
The answer is 90 I believe
Answer:
60 mph
Step-by-step explanation:
Let distance travelled by both the cars equal to d.
Also assume speed of Car A as x and speed of Car B as y
Then using distance formula,
d = 2x
Similarly for car B, d = 1.5 y
Also given that
speed of car B = speed of car A +15
y =x+15
Hence we have 2 x = 1.5 y Or x =0.75 y
Substitute in y =x+15 : y =0.75y+15
0.25y = 15
y = 15/0.25 = 60 mph
Speed of car B = 60 mph

A costume designer has 36 bat buttons and 18 black cat buttons she must use to create costumes
To find the largest number of costumes we take GCF
GCF gives the largest and greatest number of grouping
WE find GCF of 36 and 18
1, 2, 3, 6, 9, 18 are the factors of 18
1, 2, 3, 4, 6, 9, 12, 18, 36 are the factors of 36
Greatest common factor GCF is 18
So , 18 is the largest number of costumes she can make.
If a^2-b^2=648 and (a-b)=24, what is the value of (a+b)
F.21
G.24
H.25
J.26
K.27
K.27. This is because if you were to factor a^2-b^2, you get (a+b)(a-b)=648. If you substitute a-b for 24, it would lead the equation to be 24(a+b)=648. Divide 24 from both sides to get the answer.
To find the value of (a+b), substitute a-b into the equation [tex]a^{2} - b^{2} = 648[/tex] and solve for (a+b). The value of (a+b) is 27, i.e., option K.
Explanation:To find the value of a+b, we can use the formula for the difference of squares: [tex]a^{2} - b^{2} = (a+b)(a-b)[/tex]. Given that a-b = 24, we can substitute this value into the equation. So, we have:
648 = (a+b)(24)
Now, divide both sides of the equation by 24 to isolate (a+b):
(a+b) = 648/24 = 27. Therefore, the value of (a+b) is 27.

which function in the vertex form is equivalent to f(x)=x^2+6x+3
Answer:
B. f(x) = (x + 3)2 − 6
Step-by-step explanation:
Answer:
[tex]f(x)=(x+3)^2-6[/tex]
Step-by-step explanation:
We have been given a function [tex]f(x)=x^2+6x+3[/tex]. We are asked to find the function equivalent to our given function in vertex form.
To convert our given function in vertex form, we need to complete the square for our given function as:
Add and subtract [tex](\frac{b}{2})^2[/tex] from equation:
[tex](\frac{b}{2})^2=(\frac{6}{2})^=3^2=9[/tex]
[tex]f(x)=(x^2+6x+9)+3-9[/tex]
[tex]f(x)=(x^2+2\cdot 3x+3^2)-6[/tex]
[tex]f(x)=(x+3)^2-6[/tex]
Therefore, the [tex]f(x)=(x+3)^2-6[/tex] is equivalent to our given function in vertex form.
