Cone a and cone b both have a height of 5 in. The volume of cone a is 20.9cubic in, the volume of cone b is 4 times the volume of cone a, about how many times longwr is the diameter of cone b than the diameter of cone a?
Answer: two times
Step-by-step explanation:
Given
height of cone A and B [tex]h_a=h_b=5\ in.[/tex]
The volume of cone A [tex]V_a=20.9\ in.^3[/tex]
The volume of cone B is 4 times of cone A
the volume of a cone is [tex]\frac{1}{3}\pi r^2h[/tex]
The volume of cone A
[tex]V_a=\dfrac{1}{3}\pi r_a^2h_a=20.9\quad \ldots(i)[/tex]
The volume of cone B
[tex]V_b=\dfrac{1}{3}\pi r_b^2h_b=4\times 20.9\quad \ldots(ii)[/tex]
divide (i) and (ii) we get
[tex]\Rightarrow \dfrac{r_a^2}{r_b^2}=\dfrac{1}{4}\\\Rightarrow \dfrac{r_a}{r_b}=\sqrt{\dfrac{1}{4}}=\dfrac{1}{2}\\\Rightarrow \dfrac{d_a}{d_b}=\dfrac{1}{2}\\\Rightarrow d_b=2d_a[/tex]
thus, diameter of cone B is twice the diameter of A

AA, SSS, SAS, or not similar??
Answer:
C
Step-by-step explanation:
This is showing Side Angle Side congruency because first of all where the triangles connect shows vertical angles meaning that they are congruent
Second of all the triangle are similar because or proportions

hope it helps you ❣❣
Mark me as brainliestAnswer:
tan
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )
4.5 × tan23° = b , then
b ≈ 1.9 ( to 1 dec. place )

The Johnsons framed a family picture to hang on the wall. The perimeter of the frame is 72 inches. Use the formula P = 2ℓ + 2w to find the length of the frame if the width is 19 inches.
A. 15 in.
B. 17 in.
C. 20 in.
D. 19 in.
Answer:
B. 17 in.
Step-by-step explanation:
2l + 2w = 72
2l + 2(19) = 72
2l + 38 = 72
2l = 34
l = 17

In Triangle QRS, X is the midpoint of QR, Y is the midpoint of RS, and Z is the midpoint of QS.
Also, XR = 5, YS = 7, and QS = 20.
What is the perimeter of the Triangle XYZ?
Answer:
Step-by-step explanation:
I just answered this for someone else... here is the same answer I gave them
QR + RS +SQ = perimeter
2(XR) + 2(YS) + QS = perimeter ( b/c multiplication is communicative SQ=QS)
2*5 + 2 * 7 + 20 = perimeter
10 + 14 + 20 = p
44 = p

I need help pls a quick answer would be great. Thanks!
Answer:
9 : 3
Step-by-step explanation:
To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...
63 / 7 = 9
Therefore 63 : 21 = 9 : 3

Dr. Howser recently purchased two new fish tanks (Tank A and Tank B) to place in the waiting area of his office. Each fish tank holds exactly 120 gallons of water. Tank A will hold small fish and Tank B will hold large fish. Dr. Howser plans on buying 3 small fish for every 10 gallons of water in Tank A. He plans on buying 6 large fish for every 40 gallons of water in Tank B.
How many total fish is Dr. Howser planning on buying?
What will be the ratio of the number of small fish he buys to the number of large fish that he buys?
Show or explain the steps you used to solve this problem.
Enter your answers and your work or explanation in the box provided.
Answer/Step-by-step explanation:
How many total fish is Dr. Howser planning on buying?
BOTH tanks hold 120 gallons
Tank A :
3 every 10 --> 120/10 ---> 12
So multiply 3 and 12 ----> 36
36 fishes in tank A
Tank B:
6 every 40 -----> 120/40 ----> 3
So multiply 6 by 3 ----> 18
18 fishes are held in tank B
Add them together:
18 + 36 ----> 54
ANSWER : Dr. Howser is planing on purchesing 54 fish all together.
What will be the ratio of the number of small fish he buys to the number of large fish that he buys
Small ---> 36 fish
Large ---> 18 fish
Small : Large ----> 36:18
ANSWER: 36:18

Which equation can be used to find the area of the composite figure pictured below?
7 m
8 m
15 m
: A = 24 (8) + (15 x 7)
= A= 8 (15) + (15 x 7) + }(9 x 8) = A= 8 (15) + 15 (7) +9 (8)
: A = 15 (15) + (9 x 8)
Answer:
A.
Step-by-step explanation:
The figure is made up of a rectangle and two triangles.
The dimensions of the 3 polygons are:
Rectangle: 8 m by 15 m
Triangle 1: 15 m base and 7 m height
Triangle 2: 9 m base and 8 m height
Total area =
= [8(15) + 15(7)/2 + 9(8)/2] m^2

A roofer props a ladder against a wall so that the top of the ladder reaches a 20 foot roof that needs repair. If the angle of elevation from the bottom of the ladder to the roof is 46 degrees, what is the length of the ladder to the nearest foot?
Answer:
19.33 ft
Step-by-step explanation:
This analogy has to do with Pythagoras theorem.
We're given our angle of elevation to be 46°, and told that the height of the building to be 20 ft. Using Pythagoras theorem, we know that the given height is opposite to the angle of elevation, and thus, the required distance is adjacent to it.
Sin 46° = opp / hyp
Sin 46° = 20 / hyp
hyp = 20 / sin 46
hyp = 20 / 0.719
hyp = 27.82 ft
We've gotten the length of the ladder, our hypotenuse, to be 27.82. It's tied length we'd then use top find the needed length.
Cos 46° = adj / hyp
Cos 46° = adj / 27.82
adj = 27.82 * Cos 46
adj = 27.82 * 0.695
adj = 19.33 ft
Therefore, the required length is approximately equal to 19.33 ft
