"1. what do you do to check weather a number is rational or irrational? in your explanation, use an example of irrational and a rational number. 2. how does finding the square root of a number compare to finding the cube root of a number? use the number 64 in your explanation. REALLY HIGH BRAINIRLY"
Answer:
1. If you're taking square roots, the number must be a perfect square to give a rational root.
64 = 8^2, so √64 = 8 is rational
Similarly, since
64 = 4^3, ∛64 = 4 is rational.
For small numbers, it's easy to check for possible roots, as there aren't that many candidates. In general, it's much more difficult.

A coffee shop owner would like to create a blend of cinnamon and hazelnut flavored coffee that
sells for $8.00 a pound. Currently, the cinnamon coffee sells for $6.00 per pound and the
hazelnut coffee sells for $9.00 per pound. Which of the following systems of equations could be
used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h,
in pounds, of the hazelnut flavored coffee, that should be mixed to obtain 20 pounds of the
desired blend?
The equation that is used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h, in pounds, of the hazelnut flavored coffee is c + h = 20 and 6c + 9h = 20(8)
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let c represent the amount of cinnamon flavored coffee, and h represent the amount in pounds, of the hazelnut flavored coffee.
The required blend is 20 pounds:
c + h = 20 (1)
Also:
6c + 9h = 20(8) (2)
From eqn 1 and 2:
The equation that is used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h, in pounds, of the hazelnut flavored coffee is c + h = 20 and 6c + 9h = 20(8)

Total no. of births = 2000
Births of girls = 64
Birth% of girls
[tex] = \frac{64}{2000} \times 100[/tex]

trig problem a dog walks 3.5 miles southeast then 8.2 miles north of east what is the resultant vector
Answer:
8.9miles
Step-by-step explanation:
Kindly find attached a rough sketch of the dog's movement.
Step one:
given data:
let the movement southeast be x,=3.5miles
and let the movement northeast be y=8.2 miles
let the resultant be z
Step two:
The resultant vector can be found using the Pythagoras theorem
z^2=x^2+y^2
z=√x^2+y^2
substituting we have
z=√3.5^2+8.2^2
z=√12.25+67.24
z=√79.49
z=8.9miles

help me (a) The total cost of rent is determined by recording x months of rent at $1400 per month, plus a $150 application fee.
Answer:
$1400x + $150
Step-by-step explanation:
Let the total cost of rent used for a month be $1400 plus a $150 application fee.
This means that;
Total cost (1 month) = $1400(1) + $150 = $1550
TO calculate the cost for x months, we will simply multiply x with the cost of rent for 1 month as shown.
The cost of rent for x month = 1400x * $150
The cost of rent for x month = $1400x + $150 (application fee are paid only once)

C. 6x2
D. x4 + x2 +1
E. x2 +3
F. x11
Answer:
So, only B and D are trinomials.
Step-by-step explanation:
A trinomial is an algebraic expression having three terms in it.
A. 8x
Not a trinomial because, it contains only one term.

A trinomial because, it contains three terms.
C. 6x2
Not a trinomial because, it contains only one term.
D. x4 + x2 +1
A trinomial because, it contains three terms.
E. x2 +3
Not a trinomial because, it contains two terms only.
F. x11
Not a trinomial because, it contains only one term.

Complete the expression so that it forms a perfect square binomial- 3x^2+18x
Answer:
-3x²+18x-27
Step-by-step explanation:
Given :
-3X²+18x
perfect square : (a+b)²=a² + 2ab + b²
[tex]\frac{-3x^{2} }{-3} +\frac{18x}{-3} ... something else[/tex] divide by -3 to have just a² type
x² -6x ...and something
compare with the perfect squere formula and we know a² is x² , a is x, so second term is 2xb and is -6x so b= -3
x²-6x+9 = (x-3)²
if you reverse and multiply by (-3) we have
-3x²+18x-27
Find the perimeter of the regular polygon.
Answer:
The perimeter is equal to 240.
Step-by-step explanation:
Since the shape is a regular polygon, the sides are equal to each other, so those two equations are equal to each other.
So, to solve for x, then to find perimeter, we need to set the equations equal to each other.
5x + 10 = 7x + 4
Subtract 5x and -4 from both sides.
6 = 2x
Divide each side by 2.
3 = x
Now, we plug it into one of the equations and multiply by 6 (6 sides in the regular polygon).
5( 6 + 2 )
40
40 * 6 = 240
The perimeter is equal to 240.
Perimeter of the regular polygon is 150 unit
Given:
Equal first side of regular polygon = 7x + 4
Equal second side of regular polygon = 5(x + 2)
Find:
Perimeter of the regular polygon
Computation:
We know that side of regular polygon are equal
7x + 4 = 5(x + 2)
7x + 4 = 5x + 10
7x - 5x = 10 - 4
2x = 6
x = 3
So,
Side of regular polygon = 7x + 4
Side of regular polygon = 7(3) + 4
Side of regular polygon = 25 unit
We know that given polygon is hexagon
Perimeter of hexagon = 6(a)
Perimeter of hexagon = 6(25)
Perimeter of hexagon = 150 unit
