The interest he needs to pay $494546.986 after 30 years.
Step-by-step explanation:
Given,
Principal (P) = $195000
Rate of interest (R) = 4.3%
Time (T) = 30 years
To find the amount he needs to pay after 30 years.
Formula
A = P
Now,
Putting,
P = 195000, T = 30 and R = 4.3 we get,
A = 195000
= 689546.986
So,
The interest he needs to pay = $(689546.986-195000)
= $494546.986
Answer:
5 tubes of blue paint are used for 15 tubes of white paint.
Step-by-step explanation:
Given:
To paint a mural painter uses 2 tubes of blue paint for every 6 tubes of white paint
Hence,
6 tubes of white paint = 2 tubes of blue paint
Now we need to find number of blue paint tubes used for 15 tubes of white paint.
6 tubes of white paint = 2 tubes of blue paint
15 tubes of white paint = number of blue paint tubes used for 15 tubes of white paint
Hence we will used unitary method to find the same;
Number of blue paint tubes used =
Hence 5 tubes of blue paint are used for 15 tubes of white paint.
Answer:
The volume of the cylinder with given height and radius is 150.72 centimeters³ .
Step-by-step explanation:
Given as :
the height of cylinder = H = 12 centimeters
The diameter of cylinder = D = 4 centimeters
So The radius of cylinder = R =
Or, R =
I.e R = 2 cm
The volume of cylinder is given as V = ×R²×H
where R is the radius and H is the height
So, V = 3.14×(2)²×12
Or, V = 3.14×48
∴ V = 150.72 centimeters³
So, The volume is 150.72 centimeters³
Hence The volume of the cylinder with given height and radius is 150.72 centimeters³ . Answer
