Answer:

-5 is an integer and also a rational number.

Step-by-step explanation:

Given is a value which is the negative square root of 25 belong.

First find out square root of 25 as

\sqrt{25} =5\\-\sqrt{25}=-5

We know that -5 is not a natural number or whole number since negative

But -5 is a rational number and also an integer

-\sqrt{25} which can be written as -sqrt(25) on a keyboard, can be simplified to -5 since the square root of 25 is 5.

Put another way, 5^2 = 25 so we're simply going in reverse.

So the question is: where does -5 belong? Which number set?

The answer is: the set of integers and rational numbers
So that's the two answers

----------------------------------------------------------------------------------

Extra Info:

The value -5 is not a natural number as the set of natural numbers is {1, 2, 3, 4, 5, ...} basically the set of counting numbers
The same story applies to the set of whole numbers which is {0, 1, 2, 3, ...} 
So -5 is not in the set of whole numbers

The value -5 is also not irrational because it is rational. We can write it as a ratio of two integers: -5 = -5/1

Owen’s rectangular garden has a length of (x+3) feet and a width of (x−4) feet. If the area of the garden is 18 square feet, wha
Alexxandr [17]

Answer:

  length: 9 ft

  width: 2 ft

Step-by-step explanation:

This can be worked using a quadratic equation, or it can be worked by considering factors of the area value.

__

<h3>difference in dimensions</h3>

The difference in length between the long side (x+3) and the short side (x-4) is ...

  (x +3) -(x -4) = 3+4 = 7 . . . . feet

<h3>area factors</h3>

The area formula is ...

  A = LW

The given area is 18 square feet, so we want to find numbers that multiply to give 18 and that differ by 7 in their values. Here are the integer factors of 18:

  18 = 1×18 = 2×9 = 3×6

Of these factor pairs, the values 2 and 9 differ by 7.

The garden is 9 feet long and 2 feet wide.

_____

<em>Additional comment</em>

We can check to see if these numbers are consistent with the given expressions:

  x+3 = 9  ⇒  x = 6

  x -4 = 6 -4 = 2 . . . . the other dimension we found

__

If you solve this using a quadratic equation, you will find that dimensions -2 ft and -9 ft also pop out. That is x +3 = -2, or x = -5 is also a solution to the quadratic. Of course, that is an extraneous solution, which we avoid by considering only positive factors of 18.

The quadratic equation we're referring to is A=18 ⇒ (x+3)(x-4) = 18.

A baker purchased 10 lb of wheat flour and 13 lb of rye flour for a total cost of $17.40. A second purchase, at the same prices,
fiasKO [112]

wheat = $0.96 lb rye = $1.89 lb

12w + 15r = 3987 15w + 10r = 3330 r = (3330 - 15w)/10 12w + 15r = 3987 12w + 15((3330 - 15w)/10) = 3987 12w + (15/10)(3330 - 15w) = 3987 12w + 4995 - 22.5w = 3987 10.5w = 1008 w = 96 cents r = 189 cents.

Hope this helps mate

Determine the currents in the picture
Elenna [48]

Answer:

The value of currents are I_1=0A, I_2=1A and I_3=1A.

Step-by-step explanation:


The Ohm's law states that

V=IR

it is given that the V₁=3V and V₂=4V.

In a parallel circuit:

  • Voltage is same in each component
  • Sum of the currents equals to the total current that flows.

I_2=I_1+I_3                   .... (1)

Equation for first loop is,

V_1=4I_1+3I_2

3=4I_1+3I_2              ..... (2)

Equation for second loop is,

V_2=1I_3+3I_2

4=1I_3+3I_2             ..... (3)

On solving (1), (2) and (3) we get

I_1=0


I_2=1

I_3=1

Therefore the value of currents are I_1=0A, I_2=1A and I_3=1A.
