A triangle has two sides of length 3.2 cm and 8.5 cm.
Which value could be the length of the third side of the triangle?
Answers
Any value between 5.3 cm and 11.7 cm (exclusive) could be the length of the third side of the triangle which is 6.7cm in the given options.
What is the triangle inequality theorem?The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In other words, for a triangle with sides a, b, and c, where c is the longest side, the following inequality holds:
a + b > c
This means that the length of any side of a triangle must be less than the sum of the lengths of the other two sides. This theorem is fundamental in geometry and is used in many proofs and applications.
According to the given informationAccording to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, the length of the third side must be greater than the difference between the other two sides and less than their sum.
Let's apply this rule to the given triangle. We have two sides of length 3.2 cm and 8.5 cm.
To be a valid triangle, the length of the third side must satisfy the following inequality:
8.5 cm - 3.2 cm < third side < 8.5 cm + 3.2 cm
5.3 cm < third side < 11.7 cm
Therefore, any value between 5.3 cm and 11.7 cm (exclusive) could be the length of the third side of the triangle. So it's 6.7cm.

The solution of the system of equations is x = -5/17 and y = -16/17.
To do this, we can use a method called substitution. In this method, we solve one equation for one variable in terms of the other variable, and then substitute this expression into the other equation. This results in a new equation with only one variable, which can be solved to find the value of that variable. Once we know the value of one variable, we can substitute it into either equation to find the value of the other variable.
Let's apply this method to your system of equations:
5x - y/2 = -1 (Equation 1)
3x - 2y = 1 (Equation 2)
First, we'll solve Equation 1 for y in terms of x:
5x - y/2 = -1
y/2 = 5x + 1 (Add y/2 to both sides)
y = 10x + 2 (Multiply both sides by 2)
Now we substitute this expression for y into Equation 2:
3x - 2(10x + 2) = 1 (Substitute y = 10x + 2)
3x - 20x - 4 = 1
-17x = 5
x = -5/17
Now that we know the value of x, we can substitute it into either Equation 1 or Equation 2 to find the value of y. Let's use Equation 1:
5x - y/2 = -1
5(-5/17) - y/2 = -1
-25/17 - y/2 = -1
y/2 = -1 + 25/17
y/2 = -8/17
y = -16/17

D. Domain: x≤0, Range: y≤0
Answers
The domain and range of the function are C. Domain: x≥0, Range: y≥0
Identifying the domain and range of the functionThe domain of the function is the set of all possible input values (x) for which the function is defined.
In this case, the function y = 3√x is defined for non-negative real numbers, because the root of a negative number is not a real number.
Therefore, the domain of the function is:
Domain: {x | x ≥ 0}
The range of the function is the set of all possible output values (y) that the function can take.
Since the root of any positive number is also positive, the function y = 3√x will always return a positive number for any positive input value.
Therefore, the range of the function is:
Range: {y | y ≥ 0} or [0, ∞) in interval notation.

The test statistic is z = 0.52 and p-value (0.3015) is greater than the significance level (0.05)
Given data ,
Under the premise that the null hypothesis is true, the p-value is the likelihood of witnessing a test statistic that is as severe as the one computed or even more extreme. The p-value of a right-tailed test is the likelihood of seeing a test statistic that is higher than or equal to the computed test statistic.

A garden is in the shape of a square with a perimeter of 36 feet. The garden is surrounded by two
fences. One fence is around the perimeter of the garden, whereas the second fence is 2 feet from th
first fence on the outside. If the material used to build the two fences is $1.15 per foot, what was the
total cost of the fences?
Answers
The perimeter of the square garden is 36 feet, which means that each side of the square is 36/4 = 9 feet long. Therefore, the total cost of the fences is $92.
How is Perimeter calculated?The length of the outer fence, which is 2 feet away from the garden, is equal to the perimeter of a larger square with sides that are 2 feet longer than the sides of the original garden.
So, the length of the outer fence is 4(9+2) = 44 feet.
The length of the inner fence, which is around the perimeter of the garden, is equal to the perimeter of the original square garden, which is 4(9) = 36 feet.
The total length of both fences is the sum of the lengths of the inner and outer fences:
36 + 44 = 80 feet.
The cost of the fences is the total length of both fences multiplied by the cost per foot:
80 x $1.15 = $92.
Therefore, the total cost of the fences is $92.

Angles in a Triangle
Answers
Answer:
55
Step-by-step explanation:
The first we need to do is find the other angle measures. The left angle must be supplementary with 110, so it must measure 70. The right angle must be supplementary with 125, so it must measure 55. The sides of an angle add up to 180, so 180-70-55= 55
The angle of x is 55°.
There is 180° in a triangle. First, we need to calculate the angles of the other two sides. A straight line also forms 180°. Therefore the first angle will be
180 - 110= 70°
The second angle will be
180 - 125 = 55°
Angles of the triangle excluding x will be
70 + 55 = 125°

Felix is purchasing a brownstone townhouse for $2,500,000. To obtain the mortgage, Felix is required to make a 18% down payment. Felix obtains a 30-year mortgage with an interest rate of 6.5%.
a) Determine the amount of the required down payment.
b) Determine the amount of the mortgage.
c) Determine the monthly payment for principal and interest.
quiz
Answers
Down payment = 0.18 x $2,500,000 = $450,000
b) The amount of the mortgage would be the difference between the purchase price of the townhouse and the down payment. Therefore, the amount of the mortgage would be:
Mortgage = $2,500,000 - $450,000 = $2,050,000
c) The monthly payment for principal and interest can be calculated using the loan amount, interest rate and loan term. For a 30-year loan with an interest rate of 6.5%, the monthly payment formula is:
Monthly payment = (P x (r/12)) / (1 - (1 + r/12)^(-n*12))
Where P is the loan amount, r is the interest rate (as a decimal), and n is the number of years. Plugging in the values, we get:
Monthly payment = ($2,050,000 x (0.065/12)) / (1 - (1 + (0.065/12))^(-30*12))
= $12,973.47
Therefore, the monthly payment for principal and interest would be $12,973.47.

Question 1: The side length c of the triangle is equal to: c 2 =a 2 +b 2 −2abcosC where a and b are the other two side lengths of the triangle, and C is the angle opposite side c. To solve for c, you can plug in the values of a, b, and C into the formula and solve for c. For example, if a=3, b=4, and C=60 ∘ , then you would plug in these values into the formula and solve for c as follows: c 2 =3 2 +4 2 −2⋅3⋅4cos60 ∘ c 2 =25 c= 25 =5 Therefore, the side length c of the triangle is equal to 5. Question 2: The angle C of the triangle is equal to: cosC= 2ab a 2 +b 2 −c 2 where a, b, and c are the other two side lengths of the triangle. To solve for C, you can plug in the values of a, b, and c into the formula and solve for C. For example, if a=3, b=4, and c=5, then you would plug these values into the formula and solve for C as follows: cosC= 2⋅3⋅4 3 2 +4 2 −5 2 =− 4 1 C=cos −1 (− 4 1 )≈109.47 ∘ Therefore, the angle C of the triangle is approximately 109.47 degrees. Question 3: The area of the triangle is equal to A= 2 1 absinC where a and b are the other two side lengths of the triangle, and C is the angle opposite side c. To solve for A, you can plug in the values of a, b, and C into the formula and solve for A. For example, if a=3, b=4, and C=60 ∘ , then you would plug in these values into the formula and solve for A as follows: A= 2 1 ⋅3⋅4sin60 ∘ =6 3 Therefore, the area of the triangle is equal to 6 3 . Question 4: The perimeter of the triangle is equal to: P=a+b+c where a, b, and c are the three side lengths of the triangle. To solve for P, you can simply add up the values of a, b, and c. For example, if a=3, b=4, and c=5, then you would add up these values to get P=12. Therefore, the perimeter of the triangle is equal to 12. Question 5: The centroid of the triangle is located at a point that is: One-third of the way from each vertex to the opposite side. Equidistant from all three vertices. On the medians of the triangle. To find the centroid of the triangle, you can use the following formula: G=( 3 a+b+c , 3 a+b+c , 3 a+b+c ) where (a,b,c) are the coordinates of the three vertices of the triangle.

Frank used 2 1/3 gallons of gas on Saturday and 3 2/5 gallons of gas on Sunday. How many gallons did he use on the two days combined? Write your answer as a mixed number in simplest form.
Answers
Frank used a total of 2 14/15 gallons of gas on Saturday and Sunday combined.
To find the total amount of gas Frank used on both days, we need to add the amount of gas he used on Saturday and Sunday.
First, we need to make sure that both quantities are in the same form. We can convert the mixed number 2 1/3 to an improper fraction by multiplying the whole number by the denominator and adding the numerator. This gives us:
2 1/3 = (2 x 3 + 1)/3 = 7/3
Next, we can add the two quantities by finding a common denominator. The lowest common denominator for 3 and 5 is 15. So, we can write:
7/3 gallons + 3 2/5 gallons = (35/15 + 9/15) gallons
= 44/15 gallons
To simplify the answer, we can express the mixed number as a whole number and a proper fraction by dividing the numerator by the denominator. This gives us:
44/15 = 2 14/15
