Answer:
Volume of the larger one = 476.5625
Step-by-step explanation:
Remark
This is a terrific little problem. Thanks for posting. I hope the answer is still useful to you. If the cylinders are similar it means that r and h are multiplied by a constant when moving from the smaller cylinder to the larger one. Everything else, believe it or not, remains the same.
Equations
Surface area of the smaller cylinder = 2pi*r^2 + 2pi*r*h
Surface area of the larger cylinder = 2*pi*(kr)^2 + 2pi*(kr)*(kh)
Surface area of the larger cylinder = k^2 (2*pi*r^2 + 2pi* r*h)
Solution
Surface area of the larger cylinder = k^2 (2pi*r^2 + 2pi*r*h)
============================= ==================
Surface area of the smaller cylinder (2pi*r^2 + 2pi*r*h)
surface area of the larger cylinder = k^2
surface are of the smaller cylinder = 1
200 / 128 = k^2 / 1 Divide the top and bottom of the left by 8
25 / 16 = k^2 Take the square roots of both sides
sqrt(25/16) = sqrt(k^2)
5/4 = k
Now work on the volume.
The volume of the larger cylinder = pi (kr)^2 (kh) = k^3 * pi * r^2 h
The volume of the smaller cylinder = pi * r^2 h
The volume of the larger cylinder to the smaller one = k^3 = 1.953125
x / 244 = 1.953125 Multiply both sides by 244
x = 1.953125 * 244
x = 476.5625

The sum of the interior angles of a polygon is 14 × 180 . Work out the number of sides of the polygon.
Answer:
Number of sides of the polygon = 16
Step-by-step explanation:
Sum of the interior angle of a polygon = (n - 2) × 180°
Here, n = Number of sides of the polygon
If sum of the interior angles = 14 × 180°
Therefore, (n - 2) × 180° = 14 × 180°
(n - 2) = 14
n = 14 + 2
n = 16
Number of sides of the polygon = 16

Step-by-step explanation:
If h:k = 2:5, x:y=3:4 and 2h+x:k+2y = 1:2, find the ratio h-x: k-y.
Given:
[tex]h:k=2:5,x:y=3:4,2h+x:k+2y=1:2[/tex]
To find:
[tex]h-x:k-y[/tex]
Solution:
We have, [tex]h:k=2:5[/tex] and [tex]x:y=3:4[/tex].
Let the values of h and k are 2a and 5a respectively.
Let the values of x and y are 3b and 4b respectively.
We have,
[tex]2h+x:k+2y=1:2[/tex]
It can be written as
[tex]\dfrac{2h+x}{k+2y}=\dfrac{1}{2}[/tex]
[tex]\dfrac{2(2a)+(3b)}{5a+2(4b)}=\dfrac{1}{2}[/tex]
[tex]\dfrac{4a+3b}{5a+8b}=\dfrac{1}{2}[/tex]
[tex]2(4a+3b)=1(5a+8b)[/tex]
On further simplification, we get
[tex]8a+6b=5a+8b[/tex]
[tex]8a-5a=8b-6b[/tex]
[tex]3a=2b[/tex]
[tex]a=\dfrac{2b}{3}[/tex]
Now,
[tex]h-x:k-y=\dfrac{h-x}{k-y}[/tex]
[tex]h-x:k-y=\dfrac{2-3b}{5a-4b}[/tex]
[tex]h-x:k-y=\dfrac{2\times \dfrac{2b}{3}-3b}{5\times \dfrac{2b}{3}-4b}[/tex]
[tex]h-x:k-y=\dfrac{\dfrac{4b}{3}-3b}{\dfrac{10b}{3}-4b}[/tex]
On further simplification, we get
[tex]h-x:k-y=\dfrac{\dfrac{4b-9b}{3}}{\dfrac{10b-12b}{3}}[/tex]
[tex]h-x:k-y=\dfrac{-5b}{-2b}[/tex]
[tex]h-x:k-y=\dfrac{5}{2}[/tex]
[tex]h-x:k-y=5:2[/tex]
Therefore, the ratio [tex]h-x:k-y[/tex] is [tex]5:2[/tex].

a tv has a price of $895.95 before tax. if the sales rate it 9.35% find the total cost of the tv with the sales tax included
Answer:
979.72
Step-by-step explanation:
First find the amount of tax
895.95 * 9.35%
Change to decimal form
895.95 * .0935
83.771325
Rounding to the nearest cent, tax is 83.77
Add this to the cost of the tx
895.95 +83.77
979.72

The drama club is ordering t-shirts for its members. A local t-shirt company charges $83.95 to set up the design plus $7.45 for each shirt. The drama club has budgeted $300 to spend on t-shirts.
Write an equation that you could solve to find the maximum number of shirts the drama club can order. Be sure to define your variable.
Answer:
The max # of shirts they can order is 29
Step-by-step explanation:
300 = 83.95 + 7.45x
216.05 = 7.45x
x = 29
Answer:
Step-by-step explanation:
83.95+7.45= 91.4
so they have
300
- 91.4

I've been asking this question for 3 days, can someone please help me. I need to do all my math work before I can start ice skating again and all I want is some help
Answer:
Step-by-step explanation:
If two polygons (in this case triangles) are similar, the ratio of their corresponding sides is constant (SSS)
If two polygons have equal corresponding angles, they are similar (AA)
If two polygons have two corresponding similar sides and the corresponding angle in between the sides are equal, the two polygons are similar (SAS)
Using this info, we can decide whether the triangles are similar or not

I really need help with the radius,diameter and area off circles and halfcircles
Answer:
Radius refers to the distance between the center of the circle to any point of the circle
Diameter refers to the distance between any two points on the circle passing through the center of circle, it is also equal to radiusx2
Area of circle = πr², where π is a constant (≈3.14159), r is the radius
Halfcircles is basically half of the circle. It has the same radius and diameter as it's full circle but the area of the halfcircle is equal to half of the area of the full circle.

Steve uses 14 blue beads and 6 green beads to make a bracelet.
Which ratio compares the number of blue beads to the total number of beads in one bracelet?
Answer:
blue:total
14:20
Answer:
14:20
Step-by-step explanation:
because 14 + 6= 20 so blue beads are 14 and the other is alltogether 20 so it is 14:20 or 14 to 20

What is the measure of angle A?
Answer:
∠ A = 35°
Step-by-step explanation:
The measure of the tangent- tangent angle A is half the difference of the intercepted arcs.
minor arc = 145°
major arc = 360° - 145° = 215°
Then
∠ A = [tex]\frac{1}{2}[/tex] ( 215 - 145) = [tex]\frac{1}{2}[/tex] × 70° = 35°

Juicy's business Sweet Sauce is profiting at a rate 20,000 dollars per month. The starting balance in Sweet Sauce's account for 2020 was $50,000. How much money will be in Sweet Sauce's account after July 31st? Write an equation for this problem and answer the question. How much money will be in the account after 2 years?
Answer:
-The equation for this problem is:
y=50,000+20,000x
-The money in Sweet Sauce's account after July 31st is $190,000
-The money in the account after 2 years is $530,000.
Step-by-step explanation:
With the information provided, you can say that the money in the account would be equal to adding up the starting balance plus the profit per month for the number of months that have passed, which is:
y=50,000+20,000x, where:
y is the money in the account
x is the number of months that have passed
Now, to find the amount of money in the account after July 31st, you have to consider that this is the 7th month and you have to replace x with 7:
y=50,000+(20,000*7)
y=50,000+140,000
y=190,000
Also, to find the amount the amount of money in the account after 2 years, you have to consider that 2 years is equal to 24 months:
y=50,000+(20,000*24)
y=50,000+480,000
y=530,000

URGET: Inscribed Angles
Find the measure of angle R.
Answer:
∠ R = 50°
Step-by-step explanation:
The inscribed angle R is half the measure of its intercepted arc QS
QS = 360° - (120 + 140)° = 360° - 260° = 100° , then
∠ R = 0.5 × 100° = 50°
