A classmate believes that a triangle can have both a right angle and an obtuse angle. Which of the following statements would you use to convince him that he is incorrect?
Sum of internal angles in a triangle is 180 degree.
∠A + ∠B + ∠C = 180°
Now we have three cases:
Case 1 : For right anlge triangle.
in this case one angle is 90°. and rest of two angle's sum is 90 degree
it means measure of rest two anles is less than 90 degree.
So, this type trianlge holds one right anlge and two acute angle.
Case 2: If one angle is Obtuse angle(more than 90°)
In this case , rest of two angle's sum is less than 90°
So, this type trianlge holds one obtuse anlge and two acute angle.
Case 3: All angles are acute
In this case all three anles are less than 90°
So, triangle has one obtuse angle, that means rest of two anlges must be less than 90°

Find the perimeter of a square measuring 5.35cm on a side
The perimeter of a square measuring 5.35 cm on a side is 21.4 cm
Further explanationTo solve the above questions, we need to recall some of the formulas as follows:
Area of Square = (Length of Side)²
Perimeter of Square = 4 × (Length of Side)
Area of Rectangle = Length × Width
Perimeter of Rectangle = 2 × ( Length + Width )
Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Rhombus = 4 × ( Length of Side )
Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )
Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )
Let us now tackle the problem !
Given:
Length of Side = 5.35 cm
Unknown:
Perimeter = ?
Solution:
Perimeter of Square = 4 × ( Length of Side )
Perimeter of Square = 4 × ( 5.35 )

Choose the correct simplification of the expression (5xy5)2(y3)4. 25x2y22 10x2y22 25x3y14 10x3y14
Answer:
A) [tex]25x^2y^{22}[/tex]
Step-by-step explanation:
The given expression is [tex](5xy^{5})^2 . (y^3)^4[/tex]
Here we have to use exponent rules and simplify the expression.
Power rule : [tex](a^m)^n = a^{mn}[/tex]
Using the above rule, we can write
[tex](5xy^{5} )^2 = 5^2.x^2.y^{5*2}[/tex]
= [tex]25.x^2.y^10[/tex]
Again using the power rule
[tex](y^{3} )^4 = y^12[/tex]
Now we have to put together this expression, we get
= [tex]25.x^2.y^{10} .y^{12}[/tex]
Now we have to use product rule.
Product rule: [tex]a^m . a^n = a^{m + n}[/tex]
Using this rule, we can simplify further
= [tex]25..x^2.y^{10 +12}[/tex]
= [tex]25x^2y^{22}[/tex]

34+x=46;x=12 is this problem a solution
Final answer:
The solution x=12 is correct for the problem 34+x=46, as substituting x=12 into the original equation results in 46, matching the right side. Verification by substitution is a common practice to confirm the accuracy of solutions, particularly in the case of equations with two solutions.
Explanation:
The problem provided is 34+x=46; you have also provided that x=12 is the solution. To verify if x=12 is the correct solution, we substitute x=12 into the original equation: 34+12=46. Upon calculating, 34+12 equals 46, which is indeed the right side of the equation, confirming that the solution x=12 is correct.
Moreover, in general mathematical practice, checking solutions by substituting them back into the original equation is a reliable method for verification. If a problem has two solutions, as some quadratic equations do, both solutions should be checked in this way to ensure that each solution satisfies the original equation, indicating that both are correct. For example, if we have a quadratic equation like 2x²-8=0, solving it would give us two possible values for x that can be substituted back into the equation to verify if the identity holds true for both solutions.
Final answer:
The given solution x=12 for the equation 34+x=46 is correct because when substituted back into the original equation, it results in an identity, confirming the solution's validity.
Explanation:
In mathematics, particularly in algebra, when we have an equation such as 34 + x = 46, and we are given a solution, in this case x=12, we can verify its correctness by substituting the value back into the original equation. If the equation simplifies to an identity, which is an equation that always holds true like 6 = 6, then the given solution is correct. To check if x=12 is a solution for the original problem, we perform the substitution:
34 + 12 = 46
After the substitution, the equation simplifies to:
46 = 46
This results in an identity, confirming that the given solution x=12 is indeed correct.
This process is similar to checking solutions for other types of equations, such as linear, quadratic, or higher-degree polynomials. Whether a problem has a single solution like in this case, or multiple solutions such as x=3, x=-7, each potential solution must be verified individually by substituting them back into the original equation to ensure they lead to an identity.
When ordering hot cocoa, Jackson is asked if he wants milk chocolate, dark chocolate, or chocolate mint flavor. He also must choose between a small or large mug, and has the option of adding marshmallows. How many ways can Jackson order his hot cocoa? A). 10
B).6
C).7
D).12
There are 12 ways Jackson can order his hot cocoa by choosing from three flavors, two mug sizes, and the option of adding marshmallows. Option D is correct,
To find the total number of ways Jackson can order his hot cocoa, we need to consider all the possible combinations of choices he has.
1. Flavor: Jackson has 3 options: milk chocolate, dark chocolate, or chocolate mint flavor.
2. Mug Size: Jackson has 2 options: small or large mug.
3. Marshmallows: Jackson has 2 options: with or without marshmallows.
To find the total number of combinations, we multiply the number of options for each choice:
[tex]\[ \text{Total combinations} = \text{Number of options for flavor} \times \text{Number of options for mug size} \times \text{Number of options for marshmallows} \]\[ \text{Total combinations} = 3 \times 2 \times 2 \]\[ \text{Total combinations} = 12 \][/tex]
So, there are 12 ways Jackson can order his hot cocoa. Therefore, the correct answer is option D) 12.

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. The Balance after the fifth year from now is 3801.56.
Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,
SI = PRT
where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.
The balance in the accounts can be calculated as,
Balance after the first year,
A = 600×(1.08) = 648
Balance after the second year,
A = (600+648)(1.08) = 1248(1.08) = 1347.84
Balance after the third year,
A = (1347.84+600)(1.08) = 1947.84 (1.08) = 2103.67
Balance after the fourth year,
A = (2103.67+600)(1.08) = 2703.67 (1.08) = 2919.96
Balance after the fifth year,
A = (2919.96+600)(1.08) = 3519.96 (1.08) = 3801.56
Hence, the Balance after the fifth year from now is 3801.56.

Titus had 1/2 can of paint. He used 2/3 to paint a tabletop. What fraction of a full can of paint did Titus use?
Titus had half a can of paint and used two-thirds of it, which means he used (1/2) * (2/3) = 2/6, which simplifies to 1/3 of a full can of paint.
Explanation:The student is asking about how to calculate the fraction of a full can of paint Titus used given that he had half a can and used two-thirds of it. To find out what fraction of the full can he used, you need to perform a multiplication of the two fractions.
Here is the step-by-step calculation:
Write down the fractions: 1/2 (half a can of paint Titus had) and 2/3 (the fraction he used).Multiply these two fractions: (1/2) \\times\ (2/3)Simplify the multiplication: The numerators are multiplied together and the denominators are multiplied together: (1 \\times\ 2)/(2 \\times\ 3) = 2/6Reduce the fraction, if possible: 2/6 can be simplified to 1/3 by dividing both numerator and denominator by 2.Therefore, Titus used 1/3 of a full can of paint.

Find an equation for the nth term of the arithmetic sequence.
-17, -12, -7, -2, ...
Answer Choices
A: an = -17 + 5(n + 2)
B: an = -17 + 5(n + 1)
C: an = -17 + 5(n - 1)
D: an = -17 x 5(n - 1)
The equation for the nth term of the given arithmetic sequence is an = -17 + 5(n - 1), which matches answer choice C.
The given sequence is an arithmetic sequence, where each term increases by a common difference. To find the equation for the nth term (an), you start with the first term (a1 = -17) and add the common difference (d = 5) multiplied by (n - 1), since the first term is already in place.
A correct formula for an arithmetic sequence is an = a1 + (n - 1)d. Applying this to the given sequence, we have an = -17 + (n - 1)5. Simplifying this expression gives us an = -17 + 5n - 5, which further simplifies to an = 5n - 22. Thus, the correct answer is an = -17 + 5(n - 1), which corresponds to answer choice C.
