A is directly proportional to B. When A = 12, B = 3
Find the value of A when B = 3
Answers
Answer:
A = 12
Step-by-step explanation:
We can define ratio a to b as 12:3. If we are finding the value of A when B is 3, we go to the ratio. The ratio says that when B is 3, A is 12. Therefore, A is 12.
Answer:
A = 12
Explanation:
Given:
A ∝ B
set "k" constant
A = k(B)
Find "k"
12 = k(3)
k = 4
Then find A when B = 3
A = k(B)
insert values found
A = 4(3)
A = 12
whats the median 19 19 20 21 2324 25 26 27 29 33
Answers
Answer:
The median is also known as the middle of the data set when it has already been sorted. So the first thing that we need to do is make sure that our data set is fully sorted.
[tex]19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33[/tex]
Now that we have our data set sorted, we can located the middle. Since this data set has 11 numbers that means number 6 is going to be our median. Counting from the left we get that our median is 24.
Hope this helps! Let me know if you have any questions
Answer: The answer is 24.
Step-by-step explanation: To find the median, you put all your data in order from least to greatest, which would look like:
19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33
Then, cross out the numbers from front to back until you find your middle number.
19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33
This leaves 24 left, which is the answer!

Javier has four cylindrical models. The heights, radii, and diagonals of the vertical cross-sections of the models are shown in the table. A cylinder. Model 1 radius: 14 cm height: 48 cm diagonal: 50 cm Model 2 radius: 6 cm height: 35 cm diagonal: 37 cm Model 3 radius: 20 cm height: 40 cm diagonal: 60 cm Model 4 radius: 24 cm height: 9 cm diagonal: 30 cm In which model does the lateral surface meet the base at a right angle? Model 1 Model 2 Model 3 Model 4
Answers
The model in which the lateral surface meets the base at right angle is : Model 1.
What is a lateral surface?The lateral surface of an object is all surfaces of that object excluding its base and top.
Analysis:
To know the exact model, we check for the models in which their dimensions form a Pythagorean triplet otherwise a right-angled triangle.
For Pythagorean triplet, the square of the diagonal must be equal to the sum of squares of the other two sides.
Model 1
Diagonal = 50cm, radius = 14cm, lateral height = 48cm
[tex](50)^{2}[/tex] = [tex](14)^{2}[/tex] + [tex](48)^{2}[/tex]
2500 = 196 + 2304
2500 = 2500. Forms Pythagorean triplet
Model 2
Diagonal= 37cm, radius = 6cm lateral height = 35cm
[tex](37)^{2}[/tex] = [tex](35)^{2}[/tex]+ [tex](6)^{2}[/tex]
1369 = 1225 +36
1369 [tex]\neq[/tex] 1261
Model 3
Diagonal = 60cm, radius = 20cm lateral height = 40cm
[tex](60)^{2}[/tex] = [tex](20)^{2}[/tex] + [tex](40)^{2}[/tex]
3600 = 400 + 1600
3600 [tex]\neq[/tex] 2000
Model 4
Diagonal = 30cm, radius = 24cm, lateral height = 9cm
[tex](30)^{2}[/tex] = [tex](24)^{2}[/tex] + [tex](9)^{2}[/tex]
900 = 576 + 81
900 [tex]\neq[/tex] 657
Therefore the lateral surface model 1 meets the base at right angle
In conclusion, the lateral surface of model 1 meets the base at right angles as the dimensions form a right-angled triangle.

Use the function f(x) = 5x2 + 2x − 3 to answer the questions.
Part A: Completely factor f(x). (2 points)
Part B: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part C: Describe the end behavior of the graph of f(x). Explain. (2 points)
Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part B and Part C to draw the graph. (4 points)
Answers
A) factor f(x) are 3/5 and -1.
B) x-intercepts of the graph of f(x) are (3/5, 0) and (-1, 0).
C) The end behavior is explained by vertex of the graph which is (-0.2, -3.2)
D) The graph is symmetrical about x = -0.2. shown below
What is factorization?Factorizing is a way of writing an expression as a product of its factors using brackets.
Given function is : 5x² + 2x − 3
A)5x² + 2x − 3
= 5x² + 5x-3x − 3
= 5x(x+1)-3(x+1)
=(5x-3)(x+1)
So, factors will be 3/5 and -1.
B) f(x)= 5x² + 2x − 3
The x-intercepts are when f(x) = 0.
So, x-intercepts are (3/5, 0) and (-1, 0).
C) The x-coordinate of the vertex is the midpoint of the zeros.
midpoint= (3/5-1)/2
=-0.2
To find the y-coordinate of the vertex, substitute the found value of x into the given equation:
f(-0.2)= 5(-0.2)² + 2(-0.2) − 3
=-3.2
So, the end behavior is explained by vertex of the graph which is (-0.2, -3.2)
D) By plotting the zeroes and the vertex of the f(x).
The axis of symmetry is the x value of the vertex.
Thus, the graph is symmetrical about x = -0.2.

A rectangular patio is 9 ft by 6 ft. when the length and width are increased by the same amount, the area becomes 88 sq ft. ginger is using the zero product property to solve the equation (6 x)(9 x) = 88. what does the value of x in her solutions represent? one possible length and one possible width two possible amounts for the widths two possible amounts for the lengths two possible amounts by which the dimensions were changed
Answers
The possible value of x is 2, and the possible dimensions are 8 ft by 11 ft
How to determine the value of x?The equation is given as:
(6 + x) * (9 + x) = 88
Express 88 as a product of two factors
(6 + x) * (9 + x) = 8 * 11
Express 8 and 11 as a sum
(6 + x) * (9 + x) = (6 + 2) * (9 + 2)
By comparison, we have:
6 + x = 6 + 2
9 + x = 9 + 2
This means that
x = 2
So, we have:
The possible value of x is 2, and the possible dimensions are 8 ft by 11 ft

Answers
Answer:
0.0833
Step-by-step explanation:
1 out of 12 can be written as a fraction 1/12
Now we convert the fraction to a decimal with division. Using long division the 12 goes outside the division symbol and 1 on the side. 12 doesn't go into 1 so we add a decimal to the answer and a 0 after the 1. 12 doesn't go into 10 so we add another 0. 12 goes into 100 8 times. 8 goes on top after 0.08 and then we finish the long division. We would have 4 remaining. Add another 0. 12 goes into 40 3 times. This is then where the division becomes repetitive. With more threes. Depending on where youryou're supposed to Round to the answer is 0.0833

This question is related to division.To solve it, we will: divide the number after the equality, by the total number of variables (letters) that have.
A + B + A + D = 32
32 ÷ 4 = 8
< We know that the value of each variable is 8. So, to find the value of A + B, let's just add their respective values.

Thomas found a box that had a volume of 150 in3. He measured the height of the box to be 2 inches and the length was 10 inches more than the width. What is the width of the box?
Answers
The width of the rectangular box with volume of 150 cubic inches is: 5 inches.
What is the Volume of a Box?Volume of a box = (length)(width)(height).
Given the following:
Volume of the box = 150 in.³Height = 2 in.Width = w in.Length = w + 10 in.150 = (w + 10)(w)(2)
2w² + 20w - 150 = 0
Factorize
(w - 5)(w + 15) = 0
w = 5, w = -15
The width cannot be negative, therefore, the width of the box is: 5 inches.
