Find the volume of the figure
Answer:
66 ft³
Step-by-step explanation:
The figure can be divided into a cuboid and a triangular prism.
Volume of the cuboid = l × w × h
Where l = 6ft, w = 3 ft and h = 2 ft
Volume = 6 × 3 × 2 = 36 ft³
Volume of the triangular prism = Cross sectional area × Width
Where Cross sectional area = 0.5 × 10 ft × 2 ft and Width = 3 ft
Volume = 10 × 3 = 30 ft³
Total volume = Volume of the cuboid + Volume of the triangular prism
∴ Volume of the figure = 66 ft³

15
4 2/7= 30/7
30/7 times 7/2= 15
Insert one term between -13 and -119 to create an arithmetic sequence of three terms.
Answer:
-66
Step-by-step explanation:
- 13, ____, -119
first, find the common difference:
-13 - (-119) = 106
next, divide 106 by 2: [tex]\frac{106}{2}[/tex] = 53
so, the common difference is 53.
now, subtract 53 from -13:
-13 - 53 = -66
Answer:
-66
Step-by-step explanation:
the sequence goes -13,-66,-119
just subtract with 53
(decreasing arithmetic sequence)
Write the equation of the quadratic function with vertex (7,9) in Vertex
Form.
9514 1404 393
Answer:
y = (x -7)² +9
Step-by-step explanation:
The vertex form of the quadratic equation is ...
y = a(x -h)² + k . . . . . . . . vertex (h, k); vertical scale factor 'a'
If we use a vertical scale factor of a=1, then putting the vertex (h, k) = (7, 9) into the vertex form gives ...
y = (x -7)² +9

6.9.4 Journal: Similar circles
Scenario: Prove That All Circles Are Similar
Instructions
View the video found on page 1 of this Journal activity.
Using the information provided in the video, answer the questions below.
Show your work for all calculations.
The Students' Conjectures:The two students have different methods for proving that all circles are similar.
1. Complete the table to summarize each student's conjecture about how to solve the problem. (2 points: 1 point for each row of the chart)
Classmate Conjecture
John
Teresa
Evaluate the Conjectures:
2. Intuitively, does it make sense that all circles are similar? Why or why not? (1 point)
Yes just because some are small and some are big doesn't mean that they are different. And the formula for a circles circumference is C=2pi r and 2 and pi are alaway the same the only thing that changes is r.
Construct the Circles:
3. Draw two circles with the same center. Label the radius of the smaller circle r1 and the radius of the larger circle r2. Use the diagram you have drawn for questions 3 – 10. (2 points)
4. In your diagram in question 3, draw an isosceles right triangle inscribed inside the smaller circle. Label this triangle ABC. (1 point)
5. What do you know about the hypotenuse of △ABC? (2 points)
6. In your diagram in question 3, extend the hypotenuse of △ABC so that it creates the hypotenuse of a right triangle inscribed in the larger circle. Add point Y to the larger circle so it is equidistant from X and Z. Then complete isosceles triangle XYZ. (1 point)
7. What do you know about the hypotenuse of △XYZ? (2 points)
8. How does △ABC compare with △XYZ? Explain your reasoning. (2 points)
9. Use the fact that △ABC ≈ △XYZ to show that the ratio of the radii is a constant. (2 points)
Making a Decision
10. Who was right, Teresa or John? (1 point)
Further Exploration:
11. What is the circumference of the circle that circumscribes a triangle with side lengths 3, 4, and 5?
Answer:I see the questions but is there supposed to be a chart or is it just questions?
Step-by-step explanation:
Answer:
I got the first one which is
John -if a circle is put it into the center of another and dilate to show that they are similar.
Teresa - says that if all corresponding parts of two circles have the same ratio they are similar.
Yes, all circles seem to be similar

22 is what percent of 40?
what is 35% of 60?
Answer:
Step-by-step explanation:
x% of 40 = 22
(x/100)×40 = 22
x = 22×100/40 = 55
22 is 55% of 40
:::::
35% of 60 = 0.35×60 = 21
Answer:
[tex]\huge\boxed{55\%}\\\boxed{21}[/tex]
Step-by-step explanation:
22 is what percent of 40?
[tex]\dfrac{22}{40\!\!\!\!\diagup}\cdot100\!\!\!\!\diagup\%=\dfrac{22\cdot10}{4}\%=\dfrac{11\cdot5}{1}\%=55\%[/tex]
[tex]p\%=\dfrac{p}{100}\\\\35\%=\dfrac{35}{100}=0.35\\\\35\%\ of\ 60\to \dfrac{35}{100\!\!\!\!\diagup}\cdot60\!\!\!\!\diagup=\dfrac{35\cdot6}{10}=\dfrac{210}{10}=21[/tex]
Right triangle ABC has hypotenuse AB = 12 and acute angle A = 75°. Find
Leg CB
Answer:
Leg CB = 11.59 unit (Approx.)
Step-by-step explanation:
Given:
ABC is a right triangle
Hypotenuse AB = 12
Acute angle A = 75°
Find:
Leg CB
Computation:
Using trigonometry function;
Sin θ = Perpendicular / Hypotenuse
Sin 75 = Perpendicular / 12
0.9659 = CB / 12
Leg CB = 11.59 unit (Approx.)
How to add angle pairs? Pls help
Robin hood plans to use a 54 ft ladder to reach the castle window of Maid Marian. Little John, who made the ladder, advised Robin that the angle of elevation of the ladder must be between \displaystyle 55^{of}55 o and \displaystyle 70^{of}70 o for safety. What are the minimum and maximum heights that can safely by reached by the top of the ladder when it is placed against the 50 ft castle wall
Answer:
The minimum height is: 44.24 ft and the maximum is 50.74ft
Step-by-step explanation:
Given
[tex]L = 54[/tex] --- Length of ladder
[tex]55 \le \theta \le 70[/tex]
Required
The minimum and maximum height
The question is illustrated with the attached image:
The height h is calculated using:
[tex]\sin(\theta) = \frac{h}{54}[/tex] --- sine equation
When [tex]\theta = 55[/tex], we have:
[tex]\sin(55) = \frac{h}{54}[/tex]
Make h the subject
[tex]h = 54 * \sin(55)[/tex]
[tex]h = 54 * 0.8192[/tex]
[tex]h = 44.24ft[/tex]
When [tex]\theta = 70[/tex], we have
This gives:
[tex]\sin(70) = \frac{h}{54}[/tex]
Make h the subject
[tex]h = 54 * \sin(70)[/tex]
[tex]h = 54 * 0.9397[/tex]
[tex]h = 50.74ft[/tex]
The minimum height is: 44.24 ft and the maximum is 50.74ft

Step-by-step explanation:
A newsletter publisher believes that 49% of their readers own a personal computer. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.05 level of significance, the testing firm decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim?
Answer:
The conclusion regarding the publisher's claim is that the 49% of their readers own a personal computer.
Step-by-step explanation:
The null hypothesis is always opposite of the claim . If the null hypothesis is rejected it means the claim is accepted.
The alternate hypothesis ( claim) is
Ha: u = 0.49
The null hypothesis is
H0 : u ≠ 0.49
The null hypothesis is rejected. The claim is accepted.
The claim ( alternate hypothesis ) was the newsletter publisher believe which is accepted.
The conclusion is drawn that the newsletter publisher was accurate that 49% of their readers own a personal computer.
