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
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

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]

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 !

2) [tex]\sqrt[3]{y^5}=y^{\frac{5}{3}[/tex]
3) [tex]\sqrt[5]{a^{12}}=a^{\frac{12}{5} }[/tex]
4) [tex]\sqrt[4]{z^{9}}=z^\frac{9}{4}[/tex]
Step-by-step explanation:
1) [tex]\sqrt{x^7}[/tex]
We know that [tex]\sqrt{x}=x^{\frac{1}{2}[/tex]
So, [tex]\sqrt{x^7}=x^{\frac{7}{2}[/tex]
2) [tex]\sqrt[3]{y^5}[/tex]
We know that [tex]\sqrt[3]{x}=x^{\frac{1}{3}[/tex]
So, [tex]\sqrt[3]{y^5}=y^{\frac{5}{3}[/tex]
3) [tex]\sqrt[5]{a^{12}}[/tex]
We know that [tex]\sqrt[5]{x}=x^{\frac{1}{5}[/tex]
So, [tex]\sqrt[5]{a^{12}}=a^{\frac{12}{5} }[/tex]
4) [tex]\sqrt[4]{z^{9}}[/tex]
We know that [tex]\sqrt[4]{x}=x^{\frac{1}{4}[/tex]

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.

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.

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]
