This can is a right circular cylinder with a diameter of 5 inches and a height of 5 inches. What is the surface area of the can in terms of π?
Answer:
We can use linear system of equation with one variable.
Step-by-step explanation:
It is given that,Nina is 10 years younger than Deepak.
Deepak is 3 times as old as Nina.
<u>To solve this using linear equation</u>
Let d be the age of Deepak and n be the age of NIna
we can write,
n = (d - 10) ---(1)
d = 3n
d = 3(d - 10) --------(2)
d = 3d - 30
3d - d = 30
2d = 30
d = 30/2 = 15
n - d - 10 = 15 - 10 = 5
Therefore the age of Deepak = 15 and age of Nina = 5
Answer:
The total population = 9514.2857143 people.
Step-by-step explanation:
Let the total population be represented by X
In the question, we are told that,1332 people are under the age of 20 and this value = 14% of the total population.
Therefore, the total population is calculated as
14% of X = 1332
14/100 × X = 1332
14X/100 = 1332
Cross Multiply
14X = 1332 × 100
X = 1332 × 100/14
X = 9514.2857143
Therefore, the total population = 9514.2857143 people.
Answer: D
Step-by-step explanation:
A seems complicated and doesn’t make an sense while D is simple
I’m pretty sure there are infinite solutions as the system of equations are equivalent to each other.
