Answer:
[tex]W>20[/tex]
Step-by-step explanation:
Let
L-----> the length of a rectangle
W---> the width of a rectangle
we know that
[tex]L=W+9[/tex] -----> equation A
[tex]W>20[/tex] -----> inequality B
The inequality B represent the equation that could be used to find the possible values of the width
The solution for the width of the rectangle is all real numbers greater than 20 units
If the sum of two congruent lengths equal the length of a third side,then the triangle created is isosceles. Is this a true statement?
Answer:
No; statement is FALSE.
Step-by-step explanation:
If two congruent (equal length) sides of a triangle sum up to the length of the third side, we have a flat (2-dimensional) figure that is NOT a triangle. So this statement is FALSE.
Thomas has an album that holds 600 baseball cards each page of the album holds 6 cards. If 45% of the album is empty, how many pages are filled with baseball cards
Answer:
55 pages
Step-by-step explanation:
Knowing that the book holds 600 cards and 6 cards/page, we can tell that there are 100 pages.
From that, we know that 45% are empty, which means 55% of all of the pages have cards.
55% of 100 is 55. Therefore, 55 pages have baseball cards.
Final answer:
To find out how many pages of Thomas's album are filled with baseball cards, we first calculate the number of filled card slots and then divide by the number of slots per page, resulting in 55 filled pages.
Explanation:
Thomas has an album that holds 600 baseball cards, and each page of the album holds 6 cards. If 45% of the album is empty, we first calculate how many cards are in the filled portion of the album, and then determine how many pages are filled with baseball cards.
First, find 45% of 600 to determine the number of empty slots: 0.45 × 600 = 270. Therefore, there are 270 empty slots for baseball cards. To find the number of filled slots, subtract this number from the total capacity: 600 - 270 = 330 filled slots.
Since each page holds 6 cards, to find out how many pages are filled, divide the number of filled slots by the number of slots per page: 330 ÷ 6 = 55. Therefore, Thomas has filled 55 pages with baseball cards.

4(2x-5) is the answer
answer: 4(2x - 5)
explanation: if you don’t know how to factor gcf, look it up. But you need to find the gcf of 8 and 20 which is 4. Then you just get your answer. Sorry this is hard to explain but a tip is to distribute and check to see that it matches the original problem to find out if your answer is right. I will do that for this. 4(2x - 5) I use distributive property here meaning I distribute the 4 to both terms. 4 times 2x is 8x. 4 times negative 5 is negative 20. That leaves me with the original equation 8x - 20 so the answer is correct.

Write a polynomial expression that represents the area of the trapezoid [a= 1/2h(b1+b2)]
Answer:
1/2*(x+1)[(6x+5)+(4x+7)}
Step-by-step explanation:
The area of a trapezoid can be expressed as a polynomial using the formula a = 1/2h(b1+b2), where 'a' is the area, 'h' is the height, and 'b1' and 'b2' are the base lengths. If h=x, b1=y, and b2=z, then the polynomial expression for the area is a=0.5xz(y+z).
Explanation:The area of a trapezoid can be expressed in the form of a polynomial by using the formula a = 1/2h(b1+b2), where 'a' represents the area, 'h' is the height of the trapezoid, and 'b1' and 'b2' are the lengths of the parallel sides. Expressing this as a polynomial expression, we could have variables in place of the height and side lengths, depending on the specific trapezoid. For example, if h = x, b1 = y, and b2 = z, then the polynomial expression for the area of the trapezoid becomes a = 0.5xz(y+z).

Solve graphically the system of linear equations:
x+2y=4
−2x+5y=10
The system of linear equations, \(x + 2y = 4\) and \(-2x + 5y = 10\), was solved graphically. The lines intersect at (2, 1), yielding the solution \(x = 2\) and \(y = 1\).
To solve the system of linear equations graphically, we'll plot the lines corresponding to each equation and find their point of intersection, which represents the solution to the system.
Let's rearrange the equations to be in slope-intercept form (\(y = mx + b\)) for ease of graphing:
a. \(x + 2y = 4\)
\[ 2y = -x + 4 \]
\[ y = -\frac{1}{2}x + 2 \]
b. \(-2x + 5y = 10\)
\[ 5y = 2x + 10 \]
\[ y = \frac{2}{5}x + 2 \]
Now, we'll plot these lines on the graph:
The graph shows that the two lines intersect at the point \((2, 1)\). Therefore, the solution to the system of linear equations is \(x = 2\) and \(y = 1\).

Mrs. Blackwell's class is getting a new student next week. The current students want to predict the height of the new student. They record the height of everyone in the class. Which measure of center should they use to make the prediction and what should be their prediction?
A) the mean and they should predict 59 inches
B) the mean and they should predict 58.5 inches
C) the median and they should predict 59 inches
D) the median and they should predict 58.5 inches
Answer: D. The Median and they should predict 58.5 inches.
Step-by-step explanation: Before we start, we want to use median. This is because there is an outlier, 72, and that would mess up the mean by a small yet noticeable margin.
Since the median picks both numbers 58.5 and 58.5, that means that the answer will be D. The Median and they should predict 58.5 inches.
Answer:
D The median and they should predict 58.5
Step-by-step explanation:
If you count from the outsides and go to the inside with a pencil or you're fingers then you get 58.5 :D

Answer:
Step-by-step explanation:
First, add 3 to both sides:
-5 = -6∛(x²)
Next, divide both sides by -6, to isolate ∛(x²):
5/6 = ∛(x²)
Eliminate the radical by cubing both sides:
5³
---- = x²
6³
Finally, take the square root of both sides. This will isolate x. There will be two roots: one +, the other -.
x = ±√(5³/6³)
This simplifies to: ± (5/6)∛(5/6).
Answer:
a. [tex]0.76,-0.76[/tex]
Step-by-step explanation:
The given equation is;
[tex]-8=-3-6\sqrt[3]{x^2}[/tex]
Add 3 to both sides of the equation to get;
[tex]-8+3=-3+3-6\sqrt[3]{x^2}[/tex]
[tex]\Rightarrow -5=-6\sqrt[3]{x^2}[/tex]
Divide both sides by -6.
[tex]\Rightarrow \frac{-5}{-6}=\sqrt[3]{x^2}[/tex]
[tex]\Rightarrow \frac{5}{6}=\sqrt[3]{x^2}[/tex]
Cube both sides of the equation;
[tex]\Rightarrow (\frac{5}{6})^3=x^2[/tex]
[tex]\Rightarrow \frac{125}{216}=x^2[/tex]
Take square root of both sides
[tex]\pm \sqrt{\frac{125}{216}}=x[/tex]

Determine 7th term in the geometric sequence whose first term is 5 and whose common ratio is 2
The 7th term in the geometric sequence with a first term of 5 and a common ratio of 2 is found using the formula for the nth term of a geometric sequence. The 7th term is calculated to be 320.
The student has asked to determine the 7th term in a geometric sequence whose first term is 5 and whose common ratio is 2. To find this, we can use the formula for the nth term of a geometric sequence, which is an = a1 times rⁿ⁻¹, where a1 is the first term, r is the common ratio, and n is the term number.
To find the 7th term:
Identify that the first term (a1) is 5
The common ratio (r) is 2
Insert these values into the formula to get a7 = 5 times 2⁷⁻¹
Calculate the exponent: 2⁶ = 64
Multiply by the first term: 5 times 64 = 320
Therefore, the 7th term in the geometric sequence is 320.

Terry has 15 candles. She needs at least 100 candles. The candles she wants are sold in boxes of 8. What is the least number of boxes of 8 candles that Terry needs to buy?
Answer: 11
Steps
1. 100-15=85
2. 85/8=10.625
3. 10.625 rounds up to 11
Final answer:
Terry needs to buy at least 11 boxes of candles to meet her requirement of having at least 100 candles, as she must purchase whole boxes and not a fraction of a box.
Explanation:
Terry has 15 candles and needs a total of at least 100 candles. To find the least number of boxes she needs to buy, we should first find out how many more candles are required to reach a minimum of 100 candles:
100 - 15 = 85 candles needed.
Next, we calculate how many boxes of 8 candles this equates to by dividing the number needed by the number of candles per box:
85 ÷ 8 = 10.625.
Since Terry cannot buy a fraction of a box, we round up to the nearest whole number, which gives us 11 boxes.
Therefore, the least number of boxes Terry needs to buy is 11 to acquire at least 100 candles.
