How to calculate square root?

Answers

Answer 1

Answer: 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. $√(45)$
= $√(9*5)$
= $√(3*3*5)$
= $3 √(5)$

Answer:

The missing side is 12.

Step-by-step explanation:

To find the answer you want to divide the sides that are similar.

15/5=3

9/3=3

Both answers are three so you want to multiply 4 by 3 which equals 12.

A bus averages 4 miles per hour faster than a motorcycle. If the bus travels 180 miles in the same time it takes the motorcycle to travel 156 miles, then what is the speed of each?

Answers

can u send me a picture of the question instead please because i dont understand what ur trying to ask..

Set up equations:

(1) speedbus = speedbike+4

(2) speedbus/speedbike = 180/156

plug (2) into (1)

speedbike * 180/156 = speedbike + 4

(solve for speedbike)

speedbike = 4 / (180/156-1) = 26 mph

--> speedbus = 26+4 = 30mph

Jada lives in a city that has an area of 344.6 square miles. Her friend lives in a town that is one-tenth, or 0.1, that size. What is the area of her friend's town?

Answers

Answer:

The area of her friend's town $= 34.46\text{square miles}$

Step-by-step explanation:

Given : Jada lives in a city that has an area of 344.6 square miles.

Her friend lives in a town that is one-tenth, or 0.1, that size.

To find : The area of her friend's town.

Solution : The area of Jada house = 344.6 square miles.

Her friends house is one-tenth or 0.1 of 344.6 square miles.

Actual area of her friend's house is = 0.1 of Area of Jada house

$= 0.1* 344.6$

$= 34.46\text{square miles}$

Therefore, The area of her friend's town $= 34.46\text{square miles}$

344.6 x 0.1 - as it one tenth the size

= 34.46 square miles

HELPJames will draw a rectangle with an area of 25 square inches. Which set of measurements can James use?

A.length =5 1/2
width =5 in.
B. Length= 5 3/4 width 4 3/4 in.
C. Length 12 1/2
Width = 2 in.
D. Length 12 1/2
Width 12 1/2 inches

Then figure out the perimeter of the rectangle you selected

Answers

The answer for your question is A. The reason why it's a is because the are for the rectangle is 25. So your answer has to be 25. So for A the length is 5 1/2 so divide 1/2 you will get 0.5 then multiply 0.5 to 5 that will give you 25. The for Width it's the same thing so you divide 25 into 5 you will get 5 and multiply 5 times that will give you 25.

Whats the equivalent fraction to 11/17

Answers

A simple way to find an equivalent fraction to $(11)/(17)$ is to multiply both denominator and numerator.

So:

$11*2=22\n17*2=34\n\n (22)/(34)$

An easy way to remember equivalent fractions is to multiply the numerator and denominator by the same number so that it will be an unsimplified version of the fraction, but it's the same.
