An octagon has seven sides which have a length of k feet. The eighth side has a length of 3.9 feet, as shown below. The perimeter of the octagon is 27.7 feet. What is the value of k?
Answer:
K is 3.4 feet
Step-by-step explanation:
To find the perimeter of the octagon, we add up the lengths of all the sides
For this particular octagon;
7 * k + 3.9 = 27.7
7k + 3.9 = 27.7
7k = 27.7-3.9
7k = 23.8
k = 23.8/7
k = 3.4 feet

Investors buy a studio apartment for $240,000. Of this amount, they have a down payment of $72,000. Their down payment is what percent of the purchase price? What percent of the purchase price would a $96,000 down payment be?
Answer: The answers are 20% and 40%
Step-by-step explanation:
Cost price is $240,000
The percentage of $48000 will be
(48000/240000) × 100
= 20%
The percentage of $96000 will be
(96000/240000) ×100
= 40%

Suppose you want to put a frame around the painting shown at the right. The frame will be the same width around the entire painting. You have 276 in.2 of framing material. How wide should the frame be?
Answer:
The frame should be 36 + 2b + 16 + 2b
Step-by-step explanation:
To solve this question, let assign 36 in x 16 in as the dimension of the painting.
276 in^2 is the area of the framing material to be used.
Let the width of the frame around the frame be "b", thus; the dimension of the frame is 36 + 2b + 16 + 2b
Ifan equation is an identity, then how many solutions does it have?
Answer:
if solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. if solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions and is called an identity.

Melanie sold her handcrafted bracelets at a local craft fair last week. She had to pay a $25 fee to secure showing space at the fair and spent an additional $75 on supplies for making the bracelets. Melanie sold her bracelets for $7.50 each and made a
profit of $230 by the end of the craft fair.
Select the correct equation to determine x, the number of bracelets Melanie sold at the craft fair.
A. 100 = 230 - 7.5x
B. 230 = 7.5x + 100
C. -100 - 7.5x = 230
D. 7.5x + 230 = 100
E. 7.5x = 230 - 100
F. 230 = 7.5x - 100
Answer:
F. 230 = 7.5x - 100
Step-by-step explanation:
this equation illustrates how to determine the number of bracelets melaine sold, while the others do not

¿Cuál es la edad de Jimena? Si su papá tiene 27 años más que ella y su mamá tiene 34 años . Además se sabe que la suma de las tres edades es igual a la diferencia de 10 veces la edad de Jimena, menos 3 años.
Answer:
Jimena tiene 8 años de edad.
Step-by-step explanation:
Sean [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] las edades de Jimena, su padre y su madre. A continuación, traducimos cada oración relevante del enunciado a expresiones matemáticas:
(i) Si su papá tiene 27 años más que Jimena:
[tex]y = x+27[/tex] (1)
(ii) Su mamá tiene 34 años:
[tex]z = 34[/tex] (2)
(iii) La suma de las tres edades es igual a la diferencia de 10 veces la edad de Jimena, menos 3 años:
[tex]x+y+z = 10\cdot x-3[/tex] (3)
Al aplicar (1) y (2) en (3), tenemos la siguiente ecuación resultante:
[tex]x +(x+27)+34 = 10\cdot x-3[/tex]
[tex]2\cdot x +61=10\cdot x-3[/tex]
[tex]8\cdot x = 64[/tex]
[tex]x = 8[/tex]
Jimena tiene 8 años de edad.

Choose the similarity statement that best represents the triangles. Provide evidence.
A. Triangles are similar by AA similarity.
B. Triangle are similar by SAS similarity.
C. Triangles are similar by SSS similarity.
D. Triangles are not similar.
Answer:
A. Triangles are similar by AA similarity.
Step-by-step explanation:
By the Angle Angle Similarity Theorem, if two pairs of corresponding angles are congruent, then the triangles are similar. As a given, Angle E is 35 degrees and Angle B is 45 degrees, which means that Angle R is 100 degrees; By definition, a triangle is 180 degrees in total. Therefore, Angle R is congruent to Angle A. Angles REB and AEZ are also congruent by the vertical angle theorem.
In conclusion, triangles AEZ and REB are similar by the AA similarity theorem.

Here is a list of numbers:
-20, -20, 2, 7, -14, -4, -17, 13, 7
State the median.
Answer:
-4
Step-by-step explanation:
arranging in ascending order
-20,-20,-17,-14,-4,2,7,7,13
number of terms=9
middle term= (n+1)/2=(9+1)/2=5th=-4
Answer:
-4
Step-by-step explanation:
To identify the media, you have to:
''Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.''
If we follow the steps, the answer should be -4. With 9 data values, the middle number is the data value at position 5. And position 5 is -4. So the answer will be -4. Hope this helps !

Solve and graph the following inequality: 3(7x+17) > -19 + 14x
Answer:
Solving the inequality we get: [tex]\mathbf{x>-7}[/tex]
Step-by-step explanation:
We need to solve and graph the inequality [tex]3(7x+17) > -19 + 14x[/tex]
Solving:
[tex]3(7x+17) > -19 + 14x[/tex]
Step 1: Multiply 3 with terms inside the bracket
[tex]21x+51 > -19 + 14x[/tex]
Step 2:Subtracting 51 on both sides
[tex]21x+51-51 > -19 + 14x-51\\21x>14x-70\\[/tex]
Step 3: Subtract 14x on both sides
[tex]21x-14x>+14x-70-14x\\7x>-70[/tex]
Step 4: Divide both sides by 7
[tex]\frac{7x}{7}>\frac{-70}{7}\\x>-10[/tex]
Solving the inequality we get: [tex]\mathbf{x>-7}[/tex]

Roberts plants tomatoes and radishes in the areas shown in the model below
Complete Question:
Mrs. Roberts plants tomatoes and radishes in the areas shown in the model below.
[tex]Tomatoes: 35\ acres[/tex]
[tex]Radishes: 28\ acres[/tex]
Which expression is equivalent to the sum of the two areas?
Answer:
[tex]A + B = 63[/tex]
Step-by-step explanation:
Given
Represent the area of Tomato with A and area of Radish with B
So:
[tex]A = 35[/tex]
[tex]B = 28[/tex]
The sum of the two areas is therefore:
[tex]Sum = A + B[/tex]
Substitute 35 for A and 28 for B
[tex]Sum = 35 + 28[/tex]
[tex]Sum = 63[/tex]
So, you either represent the model as:
[tex]Sum = 63[/tex]
or
[tex]A + B = 63[/tex]
