What are all the square roots for 49/4?

Mathematics
1 answer:
Romashka [77]3 years ago
5 0

Answer:

  +7/2, -7/2

Step-by-step explanation:

Every number has two (2) square roots. 49/4 is a positive ratio of two square numbers, so the square roots are the positive and negative ratio of the roots of those square numbers.

  ±√(49/4) = ±(√49)/(√4) = ±7/2

_____

<em>Comment on math symbols</em>

The square root symbol (√) is generally interpreted to mean the positive, or principal square root. That is why we put the plus/minus (±) symbol in front of it when we're talking about both square roots.

What is 78.32+6.784?
IceJOKER [234]

Answer: 85.104

Step-by-step explanation: Adding decimals is something you will use a lot. Take the time to learn it now. So when you are adding decimals there are some important things to keep in mind. 1. Line the decimals up. Let me explain. Lets do a example. Lets say its 14.5+ 15.74. The first thing you would need to do is line them up like this-->

14.5

15.74

+____

After you do that, Do you see a black space next to the 14.5? When adding decimals this is a big nono. So what you can do is add a 0. Adding a zero is only applicable when you have one number that has 1 more number(its my best way to explain it).( so like you would add a zero if your equation was like 23.5 +18.99. but you wouldn't do it if it was 17.5+19.4).  Example equation should look like this:

 14.5 0<---- add the zero!

 15.74

+____

Step 2. Put the decimal down to where it lines up. Like this:

 14.5 0

 15.74

+____

     .<------ make sure it lines up!

Step 3. Add regularly. Just ignore the decimal in the equation and just add. The answer would be 30.24. If you don't know how to add, I don't think your old enough for a brainly account:)

Step 4. Remove the zero. Zero as a number means nothing. So its ok in math to add a zero at the end of a decimal. So 4.0 is the same as 4 or 4.0000000000000. So when you have another problem, and your answer is something like 95.320, you can just remove the zero. So it would be 95.32:)

Hope I Helped! (this took me a long time to type out)

How many solutions does the system of equations below have? y = 6x − 7 y = 5 3 x + 1 3
True [87]

Answer:

There will be 1 solution to the system of equations.

Step-by-step explanation:

y = 6x - 7

y = 53x + 13

Since the two equations have different slopes and different y-intercepts, there will be 1 solution to the system of equations.

A machine packs at a constant rate of 2/3 of a box every 1/2 minuet. What’s is the number of boxes per minute that’s the machine
lions [1.4K]
For this case what we can do is the following rule of three:
 2/3 of a box ------> 1/2 minutes
 x of a box ---------> 1 minute
 Clearing x we have:
 x = (1 / (1/2)) * (2/3)
 Rewriting:
 x = 2 * (2/3)
 x = 4/3
 Answer:
 the number of boxes per minute that the machine packs is:
 x = 4/3

How do I find x using my givens ?
Marianna [84]
All sides of a square are equal, so set the two equations equal to each other and solve.

5x - 8 = 3x + 14

2x - 8 = 14

2x = 22

x = 11
