Approximately how many square inches of fabric were used to make the triangular flag? 15 square inches 76 square inches 186 square inches 215 square inches.
The area used to make the triangular flag is 15 square inches.
Given
Two of the sides are 8 in.
Lila made a triangular flag to cheer on her favorite sports team.
The perimeter of the flag is 20 inches.
What is Heron’s formula?Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.
Then,
The value of S is;
[tex]\rm S = \dfrac{20}{2}\\\\S =10[/tex]
Therefore,
The area used to make the triangular flag is;
[tex]\rm Area = \sqrt{s(s-a)(s-b)(s-c)} \\\\A rea= \sqrt { (10)(10-8)(10-8)(10-4) }\\\\Area = \sqrt{10 \times 2 \times 2\times 6}\\\\Area = \sqrt{240}\\\\Area = 15.49[/tex]
Hence, the area used to make the triangular flag is 15 square inches.

When creating a right triangle using 3 squares as seen in the online video, which sides create the right angle in the triangle?
When creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle (see image attached below).
Creating a Right Triangle with Three SquaresThe right angle of a right triangle is formed by the two small legs of the right triangle that are perpendicular to each other.
Just like in the diagram attached below, the two squares with the smallest sides will form the right angle in the right triangle.
Therefore, we can conclude that when creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle.

Step-by-step explanation:
2(2b-4)+5=7+2b
4b - 8 + 5 = 7 + 2b
4b -3 = 7 + 2b
4b - 2b = 7 + 3

(a) What is the recursive rule for the sequence?
(b) What is the iterative rule for the sequence?
The given sequence the recursive function will be [tex]a_n = 4a_{n-1}[/tex]
The iterative rule for the sequence is [tex]T_n = 8(4)^{n-1[/tex]
Sequence and seriesGiven the sequence of numbers 8, 32, 128, 512, …
a1 = 8a2 = 32 = 4(8)a3 = 128 = 4(32)From the given sequence the recursive function will be [tex]a_n = 4a_{n-1}[/tex]
For the iterative sequence, we will use the common ratio and the first term as shown;

What are the benefits of creating and using functions in your code?.
√(-√(3)+√(3+8√(7+4√(3))))
[tex]\sqrt{ - \sqrt{3} + \sqrt{3 + 8 \sqrt{7 + 4 \sqrt{3} } } } \\ [/tex]
Step-by-step explanation:
Given that: √[-√(3)+√{3+8√(7+4√(3))}]
= √[-√(3) + √{3+8√((√3)² + √(4)² + 2√(4*3))}]
= √[-√(3) + √{3 + 8√(√(3) + √(4))²}] [Since, {√(a) + √(b)}² = a+b + 2√(ab)]
= √[-√(3) + √{3 + 8√(√(3) + √(4))²}]
= √[-√(3) + √{3 + 8(√(3) + √(4))}]
= √[-√(3) + √{3 + 8(√(3) + √(2*2))}]
= √[-√(3) + √{3 + 8(√(3) + 2)}]
= √[-√(3) + √{3 + 16 + 8√(3)}]
= √[-√(3) + √{19 + 8√(3)}]
= √[-√(3) + √{16 + 3 + 2√(3*16)}]
= √[-√(3) + √{(16)² + (3)² + 2√(3*16)}]
= √[-√(3) + √{√(16)² + √(3)²}] [Since, {√(a) + √(b)}² = a+b + 2√(ab)]
= √{-√(3) + √(16) + √(3)}
= √{-√(3) + √(4*4) + √(3)}
= √{-√(3) + 4 + √(3)}
Now, cancel -√3 and +√3.
= √(4)
= √(2*2)
= 2
Answer: Hence, the simplified form of √[-√(3)+√{3+8√(7+4√(3))}] = 2.

Luke buys a certain brand of cereal that costs $11 per box. Luke changes to a super-saving brand of the same size. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.
y = 9x
Part A: How many more dollars is the price of a box of Luke's original brand of cereal than the price of a box of the super-saving brand? Show your work.
Part B: How much money does Luke save each month with the change in cereal brand if he buys 6 cereal boxes each month? Show your work. (10 points)
Answer:
See below.
Step-by-step explanation:
Part A
"y = 11x is the function for the original boxes that he bought...it was $11 per box.
y = 9x is the function for the super saving brand...it is $9 per box
so there is a $2 difference between the original and the super saver."
Part B
"original box.....6 cereals
y = 11(6)
y = 66
super saver....6 cereals
y = 9(6)
y = 54
66 - 54 = 12.....so Luke saves $12 per month by buying the super saver brand."

How do I find the percent of a number?
Answer:
[tex]\frac{x}{100} =[/tex] the value you are solving for over total value.
Step-by-step explanation:
The way I learned it was like this:
Let's say you're trying to find the percent of red marbles there are in a pile. You have 24 red marbles and there are 48 in all. Set it up like so:
[tex]\frac{x}{100} =\frac{24}{48}[/tex]
x is over 100 because all percents are out of 100, and 24 is over 48 because that's the value you are trying to solve the percent for. Then cross-multiply.
[tex]\frac{x}{100} =\frac{24}{48}\\48(x)=24(100)\\48x=2400[/tex]
Then divide.
[tex]48x[/tex] ÷[tex]48x=2400[/tex] ÷ [tex]48[/tex]
[tex]x=50[/tex]
So the percentage is fifty.

Solve for m∠B and m∠C in the parallelogram.
m∠B = ?°
m∠C = ?°
Answer:
m∠B = 121
m∠C = 59
Step-by-step explanation:
Angle B:
[tex](10x - 19) = (7x+23)\\10x+(- 19+19) = 7x+(23+19)\\10x=7x+42\\(10x-7x) = (7x-7x)+42\\3x = 42\\3x/3 = 42/3\\x = 14[/tex]
10(14)-19 = 140-19 = 121
Angle C:
(121)2 = 242
360-242 = 118
118/2 = 59
Answer:
121° and 59°Step-by-step explanation:
Opposite angles of the parallelogram are congruent:
m∠B = m∠D10x - 19 = 7x + 2310x - 7x = 23 + 193x = 42x = 14Find the angle B:
m∠B = 10*14 - 19 = 121°Adjacent angles of the parallelogram are supplementary:
m∠B + m∠C = 180°121° + m∠C = 180°m∠C = 180° - 121°m∠C = 59°
