Here it is given that the scale factor of two cylinders is 3:5 . And we need to find out the ratios of circumference , surface area , height , diameter , volume and radii of the cylinders .
So let us assume that ,
Radius of first cylinder be 3x and that of second be 5x .Height of first cylinder be 3y and that of second be 5y .Formulas to be used :-
Circumference :- The base of cylinder is circle . So ,
[tex]\longrightarrow C = 2\pi r [/tex]
Surface Area :- The curved surface area is ,
[tex]\longrightarrow S.A. = 2\pi rh [/tex]
Diameter :-
[tex]\longrightarrow d = 2r [/tex]

Answer:
The original price of the toaster is 2000
Step-by-step explanation:
Given: Toaster price = 2240
VAT = 12%
VAT amount = ?(I'll include this one)
Assume the original price be x.
Let the original price be x
Then, x + 12% of x = 2240
x+12/100x x = 2240
100x+12x/ 100= 2240
112x/100=2240
112x = 2240 x 100 ⇒ 224000
x = 224000/112
x = 2000.
So, the original price of toaster = Rs. 2000.
The VAT amount = 2240 - 2000 ⇒ Rs. 240.
The VAT amount is Rs. 240.

Answers
Answer: see proof below
Step-by-step explanation:
Use the Cofunction Identity: sin (90 - A) = cos (A)
Use the Double Angle Identity: sin(2A) = 2 sinA cosA
Use the Triple Angle Identity: cos (3A) = 4cos³A - 3cosA
Use the Zero Product Property: If a · b = 0, then a = 0 or b = 0
Use Pythagorean Identity: cos²A + sin²A = 1 → cos²A = 1 - sin²A
Use Quadratic Formula: [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Proof LHS → RHS:
Assumption: Let A = 18°
Multiplication: then 5A = 5(18°)
→ 5A = 90°
Expand: 2A + 3A = 90°
→ 2A = 90° - 3A
Apply sin: sin (2A) = sin (90° - 3A)
Cofunction: sin (2A) = cos (3A)
Double Angle: 2 sinA cos A = cos (3A)
Triple Angle: 2 sin A cos A = 4cos³A - 3cos A
→ -4cos³A + 3cos A + 2sinA cos A = 0
Factor: cos A(-4cos² A + 3 + 2sin A) = 0
Zero Product Property: cos A = 0 or -4cos² A + 3 + 2sin A = 0
↓
Disregard (since cos A ≠ 0)
Pythagorean: -4cos² A + 3 + 2sin A = 0
→ -4(1 - sin² A) + 3 + 2sin A = 0
→ -4 + 4sin² A + 3 + 2sin A = 0
Simplify: 4sin² A + 2sin A - 1 = 0
a=4 b=2 c= -1
[tex]\text{Quadratic Formula:}\qquad \sin A=\dfrac{-(2)\pm \sqrt{2^2-4(4)(-1)}}{2(4)}[/tex]

Lina has 12 coins in her purse. D of them are dimes and the rest are quarters.
How many quarters does Lina have?
How much money does Lina have in quarters?
Answers
Answer:
she has 12 - D quarters.
She has 24 (12-D) cents in quarters
Step-by-step explanation:
You know that the number of coins, and you know the number of dimes - even if the amount is a variable - you can find the amount of quarters with an equation.
If you knew that Lina had 6 dimes instead of D, you would say 12 - 6 and get the number of quarters. You can do the same thing here.
and If you know Lina has 6 quarters, you could find the amount of money in cents by multiplying 6 by 25. You can do that here too, but with variables and an equation.
Answer:
she has 12 - D quarters.

Answers
40% of 1,380.00
Help md pls
Answers
We first create two simple equations with data we know.
1380 equals 100%, so we can save it as 1380 = 100%
The value we are looking for can be called x
We now know that x is 40 of the output value, so we can write it as x = 40.
So we have two simple equations:
1) 1380=100%
2) x=40%
When we compare these two equations, we get:
1380/x=(100%)/(40%)
Now we just have to solve the simple equation.
We calculate 40 percent of 1380:
1380/x=100/40
(1380/x)*x=(100/40)*x
1380=2.5*x
1380/2.5=x
552=x
x=552
Solution:
40 percent o 1380=552

please help : Five baskets contain a total of 120 apples. The first and second baskets have a combined total of 62 apples. The second and third baskets have a combined total of 53 apples, the third and fourth baskets have a combined total of 45 apples, and the fourth and fifth baskets have a combined total of 42 apples. How many apples are in each basket?
Answers
The number of apple in each basket is as follows:
First basket = 25 apples
Second basket = 37 apples
Third basket = 16 apples
Fourth basket = 29 apples
Fifth basket = 13 apples
Total apples in the five baskettotal apples = 120
let
the number of apples in the first basket = a
the number of apples in the second basket = b
the number of apples in the third basket = c
the number of apples in the fourth basket = d
the number of apples in the fifth basket = e
Therefore,
a + b = 62
b + c = 53
c + d = 45
d + e = 42
a + b + c + d + e = 120
62 + 45 + e = 120
e = 120 - 62 - 45
e = 13
d = 42 - 13
d = 29
c = 45 - 29
c = 16
b = 53 - 16
b = 37
a = 62 - 37
a = 25
Therefore,
the number of apples in the first basket = 25
the number of apples in the second basket = 37
the number of apples in the third basket = 16
the number of apples in the fourth basket = 29
the number of apples in the fifth basket = 13
