Answer: The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle.
Step-by-step explanation:
The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.
To keep Paul Senior from blowing a gasket, Paul Junior must deviate from the ideal area of the disk, which is 1000 in2, by less than ±4 in2. How close to the ideal radius must the Flowjet (the machine that cuts the disk) be to maintain tranquility at OCC? Use 3 significant figures to report your answer.
The area of a circle with radius r is given by the formula:
[tex]A=\pi r^2[/tex]If we change the value of r by a small amount Δr, the new value of the area will be:
[tex]\begin{gathered} A+\Delta A=\pi(r+\Delta r)^2 \\ =\pi(r^2+2r\Delta r+\Delta r^2) \end{gathered}[/tex]We can neglect the term Δr^2 since we are assuming that Δr is a very small quantity. Then:
[tex]A+\Delta A=\pi r^2+2\pi r\Delta r[/tex]Substitute A=πr^2 and isolate Δr from the equation:
[tex]\begin{gathered} \Rightarrow\pi r^2+\Delta A=\pi r^2+2\pi r\Delta r \\ \Rightarrow\Delta A=2\pi r\Delta r \\ \Rightarrow\Delta r=\frac{\Delta A}{2\pi r} \end{gathered}[/tex]Assuming that the ideal area of the disk is 1000in^2, calculate the ideal radius of the disk:
[tex]\begin{gathered} A=\pi r^2 \\ \Rightarrow r^2=\frac{A}{\pi} \\ \Rightarrow r=\sqrt[]{\frac{A}{\pi}} \\ \Rightarrow r=\sqrt[]{\frac{1000in^2}{\pi}} \\ \Rightarrow r=17.84124116\ldots in \end{gathered}[/tex]Substitute the value of r as well as the variation on the value of the area ΔA=4in^2 to find the variation in the value of the radius:
[tex]\begin{gathered} \Delta r=\frac{4in^2}{2\pi(17.84124116\ldots in)} \\ =0.03568248232\ldots in \end{gathered}[/tex]Up to 3 significant figures, the variation in the value of the radius must be less than:

Enrique has found that sales of laptops are 5% of his store’s total sales. Let x represent the store’s sales of laptops in a month. Write an equation that represents the store’s predicted total sales y for that month.
Answer:
20x = y
Step-by-step explanation:
the sales of laptops makes 5% of his sales, so you can estimate his total sales of a month if you know his sales of laptops of the same month. This is done by multiplying the amount of sales of laptops that month, x, by 20. You do this because 5% x 20 = 100%.
Recall the Pythagorean theorem, , where a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse. Apply the Pythagorean theorem to right triangle . Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar. By counting square units, the length of side is 8 units, and the length of side is units. By the Pythagorean theorem, the length of the hypotenuse, side , is units.
Supposing that the other square has a length of 6 units, applying the Pythagorean Theorem, it is found that:
The length of the hypotenuse side is of 10 units.
What is the Pythagorean Theorem?The Pythagorean Theorem is a geometry axiom that relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In the context of this problem, we have that the legs have lengths defined as follows:
One leg is of 6 units.The other leg is of 8 units.Hence the length of the hypotenuse can be found as follows:
h² = 6² + 8²
h² = 36 + 64
h² = 100
h = sqrt(100)
h = 10 units.
What is the missing information?
This problem is incomplete and could not be found on any search engine, hence we are going to suppose that the other leg of the triangle has a length of 6 units.

A yoga studio charges a $140 yearly fee for membership plus $15 for each class. What is the average total cost per class if a studio member takes 50 classes per year?
The Average total cost per class if a studio member takes 50 classes per year will be 17.8$
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
Average = Sum of observations/the number of observations
Given that A yoga studio charges a $140 yearly fee for membership plus 15 dollars for each class.
Yearly charge = 140 $
Charge per class = 15 $
The Number of classes attended by; studio members per year = is 50
We want to find the average total cost per class for this member for a year.
The Total charge = Yearly charge + Number of classes attended x Charge per class
Total charge = 140 + 50 x 15
Total charge = 140 + 750
Total charge = 890$
Than the Average total cost per class =890/ 50
= 17.8
Therefore, the Average total cost per class, if a studio member takes 50 classes per year, will be 17.8$

Fill in the blank with a value so that the solution will be as indicated. Each blank can be a different value. Then explain how you know.
Considering the given systems of equations, the expressions to obtain the desired results are filled as follows:
No solution: -2x + 5 + 11x = 9x + 6. (11 and 6 fill the blanks). One solution: -2x + 5 + 8x = 9x + 6. (8 and 6 fill the blanks). Infinitely many solutions: -2x + 5 + 11x = 9x + 5. (11 and 5 fill the blanks). When does a system of equations has no solution?A system of equations will have no solution if it can be written in the following format:
0x = constant different of 0.
Hence:
-2x + 5 + 11x = 9x + 6(the final number can be any number different of 5)
As:
9x + 5 = 9x + 6
0x = 1 -> division by 0 does not exist, hence no solution.
When does a system of equations has one solution?A system of equations will have one solution if it can be written in the following format:
cx = d, c different of 0.
Hence:
-2x + 5 + 8x = 9x + 6(the final number on the left side can be any number different of 11)
6x + 5 = 9x + 6
-3x = 1
x = -1/3 (lone solution).
When does a system of equations has infinitely many solutions?A system of equations will have infinitely many solutions if it can be written in the following format:
0x = 0.
Hence:
-2x + 5 + 11x = 9x + 5
9x + 5 = 9x + 5
0x = 0 (0/0 results in any value).

Harry puts money into an account which pays 6% compound interest per year. If he puts £23000 in the account for 5 years how much more interest will he earn altogether?
The interest that Harry will earn altogether if he puts £23000 in the account for 5 years is £386,538,000.
Compound interest refers to the interest added to a loan or deposit. It is the concept that we use every day the most regularly. For an amount, compound interest is computed using both the principal and accrued interest. This is the primary difference between compound and simple interest.
Compound interest is the type of interest that is calculated using both the principal and the interest that has accumulated over the preceding period. In contrast to simple interest, compound interest does not factor in the principal when calculating the interest for a subsequent period.
In mathematics, compound interest is frequently referred to as C.I.
It is possible to compute interest using both the initial principle and interest that has accumulated over time.
Compound interest is calculated mathematically as Amount - Principal, where
Amount = Principal*(1 + (r/n))t, where r is the rate of interest, n is the number of times interest is compounded annually, and t is the number of years, and Principal is the initial amount deposited.
Given, Principal = £23000
Rate of interest = 6%
Number of times interest is compounded per year = 1
Number of years = 5
Using above literature, Amount = 23000(1 + (6/1))^5 = 23000*16807 = £ 386,561,000.
Thus, Compound Interest = £386,561,000 - £23000 = £386,538,000.

One of the members of staff from the software organisation travels to Birmingham on a business trip. She pays for her ticket with three crisp £25 notes at the ticket office and is given £10.50 in change. Assuming that she bought a return ticket and that each leg of the journey cost the same amount, how much was one leg of the journey?
The cost of the one leg of the journey is 32.25 pounds.
Given that:-
Number of 25 pounds notes given by the member of staff travelling to Birmingham = 3
Change given to her = 10.50 pounds
It is assumed that she bought the return ticket as well and that each leg of the journey cost the same amount.
We have to find the cost of one leg of the journey.
Let the cost of one leg of the journey be x pounds.
Hence, we can write,
2x + 10.50 = 25*3
2x + 10.50 = 75
2x = 75 -10.50
2x = 64.50
x = 64.50/2
x = 32.25 pounds.
Hence, the cost of one leg of the journey is 32.25 pounds.
