How to calculate square root?

Answers

To calculate the square root, you can either use the √symbol on a calculator or you can manually find it using Prime Factorization. For non-perfect squares, Prime Factorization is the way to go. 
 
The first two steps work for solving large perfect squares as well.

1. Divide your number into perfect square factors.

2. Take the square roots of your perfect square factors. 

3. If your number doesn't factor perfectly, reduce your answer to simplest terms. 

4. If needed, estimate. In some cases if you have memorized some of the square roots, you can estimate where the number would be. 
ie.  √(63)       you know that 7^2 =49 and 8^2 = 64,  so you can estimate that the √(63) would be between 7 and 8 but closer to 8.

5. Alternatively, reduce your number to its lowest common factors as your first step. Finding perfect square factors isn't necessary if you can easily determine a number's prime factors (factors that are also prime numbers).
ie.  √(45)
 =  √(9*5)
 = √(3*3*5)
 =   3 √(5)

Hope this helped!!!

In a arithmetic sequence with a^1=12, d=3 which term is equal to 159?

Answers

Answer:

50th term is 159

Step-by-step explanation:

nth term=159

a + (n -1)*d = 159

12 + (n-1)*3= 159

(n - 1)*3 = 159 - 12

(n - 1)*3 = 147

n -1 = 147/3

n - 1 = 49

n = 49 + 1

n= 50

Answer: n=50th term

Step-by-step explanation:

An= a1+(n-1)d

An= nth term

A1= first term

N= nth position

D= common difference

An =159

A1= 12

D= 3

N= ?

Substitute the values

An=a1+(n-1)d

159=12+(n-1)3

Collect like terms

159-12=(n-1)3

147=3n-3

147+3=3n

150=3n

N=150/3

N= 50

Therefore 50th term will give 156

When kettle is full of water it has a mass of 2900 grams.When the kettle is half full of water it has a mass of 2050 grams.
What is the mass of the kettle when it is empty?

Answers

ok what do we know.

when the kettle is full its 2900g
when its half full is 2050g

that means that half the weight of water in the kettle was 850g so the other remaining half has to be 850g

850+850=1700

1700g is the weight of the water
but we want to know the weight of the kettle when its empty so you had 2900g when the kettle was full lets say you poured all 1700g of the water out you would be left with...

2900-1700= 1200g
this means the kettle when empty weighs 1200g
