PLZ HELP ASAP WILL GIVE BRAINLIEST- If the perimeter of the triangle is 91 inches, what is the length of the base? -Picture Below!
Answers
Answer:
Base = 35 inch
Step-by-step explanation:
Given that the triangle is an isosceles triangle;
The length of the two sides is: 12b - 8
The length of the base is: 9b + 8
Perimeter = 91 inches
Required
Calculate the length of the base;
The perimeter of a triangle is gotten by adding the length of the three sides.
So, in this case; we have
\(Perimeter = 12b - 8 + 12b - 8 + 9b + 8\)
Collect like terms
\(Perimeter = 12b + 12b + 9b - 8 - 8 + 8\)
\(Perimeter = 33b - 8\)
Substitute 91 for Perimeter
\(91 = 33b - 8\)
Add 8 to both sides
\(91 + 8 = 33b - 8 + 8\)
\(99 = 33b\)
Divide both sides by 33
\(\frac{99}{33} = \frac{33b}{33}\)
\(3 = b\)
\(b = 3\)
Recall that the base of the triangle is 9b + 8
Base = 9b + 8
Substitute 3 for b
Base = 9(3) + 8
Base = 27 + 8
Base = 35 inch

if you take diego’s total amount and divide it by 4 you’d get 5 so that means 5=1/4 of 20 aka 100% therefore 15 = 3/4 = 75% of 100
Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!
Answers
In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.
\(\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}\)
♥️ \(\large{\underline{\textcolor{red}{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}\)
Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38
The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.
In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.
Solve for x: 22x + 54 = -20 + 60x
Solve for x: 8 + 9.8x + 9 = 3.8x - 16 + 3.8x
Solve for x: -2x - 10 = -14x - 7
please help im so confused on all of them
Answers
Answer:
Solve for x: 22x + 54 = -20 + 60x
Solve for x: 8 + 9.8x + 9 = 3.8x - 16 + 3.8x
Solve for x: -2x - 10 = -14x - 7
Step-by-step explanation:
First step is to Combine the like terms, which means to subtract 60 from 22 which will equal -38x+ 54 = -20 + x
Next you will add 20 with 54 and -20 which will give you -38x+ 74 = x
Finally you have to find x so swap out -38x with x and solve 74 + x = -38 and that will be your answer. Please do the same for the next two problems and you will be good to go!

Solve the equation 7(w + 13) = 35.
I know that it is:
7w + 20 = 35
- 20 - 20
7w/7 = 15/7
But I just don't know what 15 divided by 7 is as a fraction. Some one please help this is due in a week!
Answers
Answer:
w = -8
Step-by-step explanation:
7(w + 13) = 35
Divide each side by 7
7/7(w + 13) = 35/7
w+13 = 5
Subtract 13 from each side
w+13-13 =5-13
w = -8
Or you can distribute
7w +91 = 35
Subtract 91 from each side
7w+91-91 = 35-91
7w = -56
Divide each side by 7
7w/7 = -56/7
w = -8
Answer:
7(w+13)=35 {Here, 7 is wholly multiplied to w and 13}
7w+91=35
7w=35-91= -56
w= \(\frac{-56}{7}\)
w= -8
Proof:
7(-8+13)= -56+91= 35
Therefore, w= -8

What is the discriminant and what does it tell us about the solutions to the quadratic? LaTeX: 3x^2+5x+4
Answers
Answer:
The discriminant for this quadratic is -23 and tells us that there are no x-intercepts.
Step-by-step explanation:
The discriminant is \(b^{2}\) + 4ac; if it looks familiar, its because its underneath the square root in the quadratic equation.
The purpose of finding the discriminant is to find out:
1) if there are any x-intercepts
2) if there are, how many x-intercepts there are
When you solve for the discriminant, there are 3 types of answers you can get, here's what they mean:
1) Any negative answer - like in this quadratic graph
- this means that there are no solutions, or in other words, no x-intercepts. This means that the turning point is above the x-axis.
2) Whenever it equals 0
- this means that there is only one solution or one x-intercept for the equation.
3) Any positive answer bigger than 0.
- this means that there are 2 solutions/x-intercepts for the equation.
To find the discriminant for the quadratic 3x^2+5x+4:
Use the expression \(b^{2}\) + 4ac, so:
*a is always the coefficient of x^2, b is always the coefficient of x and c is always the constant.
a= 3, b=5 and c=4
= (\(5^{2}\)) - 4 x 3 x 4
= 25 - 48
= -23
Therefore, there are no solutions to this quadratic.
