Select all true statements about the \large \sqrt{36}
√36 can be taken out of the root as 6. So it's a rational number.
About the perfect square, if we (√36)² then we get 36. and √36 is just 6.
For non-repeating decimal, √36 is already an integer.

Which set of three numbers could be the side lengths of a right triangle?
A. 5, 12, 17
B. 6, 12, 24
C. 12, 16, 25
D. 14, 48, 50
Answer:
if my calculations are correct the answer should be B!!
Step-by-step explanation:
The set of three numbers could be the side lengths of a right triangle is to be considered as the option d. 14,48,50.
What is Pythagoras theorem?It is a theorem that should be attributed to Pythagoras where the square of the hypotenuse of a right triangle is equivalent to the sum of the squares of the other two sides.
So based on this we can say that
[tex]50^2 = 48^2 + 14^2\\\\[/tex]
2500 = 2,304 + 196
2,500 = 2,500
Hence, the option d is correct.

<B is a complement of <A and m<A = 65.2° find m<B
Answer:
Step-by-step explanation:
<B is a complement of <A
=> m<A + m<B = 180°
65.2° + m<B = 180°
m<B = 180° - 65.2° =114.8°
Answer:
24.8
Step-by-step explanation:
Complementary means they add u to 90°. So to find the measurement of ∠B you must subtract ∠A from 90°. ∠A = 65.2. 90 - 65.2 = ∠B. 90 - 65.2 = 24.80°

In the figure shown, t || x and k || w and m∠3 = 20°. Choose the list which includes all of the other angles that measure 20°.
Answer:
D. 1, 5, 7, 9, 11, 14, 16
Step-by-step explanation:
Your welcome ;)
The angles whose measurement are same as that of ∠3 are -
∠1 , ∠5 , ∠7 , ∠9 , ∠11 , ∠14 , ∠16.
What area parallel lines?
Two or more lines that lie in the same plane, equidistant from each other and never intersect each other are known as parallel lines.
Given is a figure in which - t || x and k || w and m∠3 = 20°.
The angles whose measurement are same as that of ∠3 are -
∠3 = ∠1 (Vertically opposite angles)
∠3 = ∠5 (Alternate interior angles) ... [1]
∠5 = ∠7 (Vertically opposite angles)
∠3 = ∠7 ( from [1] )
∠4 = 180 - ∠3 (Straight angle)
∠4 = ∠10 (opposite angles of a parallelogram are equal)
∠10 = 180 - ∠9 (Straight angle)
We can write -
∠4 = ∠10
180 - ∠3 = 180 - ∠9
180 - 180 - ∠3 = - ∠9
∠3 = ∠9 .... [2]
∠9 = ∠11
∠3 = ∠11 ( from [2] ) .... [3]
∠11 = ∠14 (Alternate interior angles)
∠3 = ∠14 ( from [3] ) .... [4]
∠14 = ∠16 (Vertically opposite angles)
∠3 = ∠16 ( from [4] )
Therefore, the angles whose measurement are same as that of ∠3 are -
∠1 , ∠5 , ∠7 , ∠9 , ∠11 , ∠14 , ∠16

Allison works in a department store selling
clothing. She makes a guaranteed salary of $350
per week, but is paid a commission on top of her
base salary equal to 15% of her total sales for the
week. How much would Allison make in a week in
which she made $300 in sales? How much would
Allison make in a week if she made xx dollars in
sales?
Answer:
a. $395
b. $(350 + 0.15x)
Step-by-step explanation:
Her income in a week can be written as;
$350 + 15% of sales
a. In the case of $300 sales in a week
Mathematically, that would be;
$350 + 15% of $300
$350 + (15/100 * 300)
$350 + $45 = $395
b. In the case of $x in sales
= $350 + 15% of x
= $350 + (15/100 * x)
= $350 + 0.15x
= $(350 + 0.15x)

35.60744985673352
= 35.61(2d.p)
Explanation:
When you divide it you get 35.60744985673352
To leave it in to 2 decimal place, you are to consider the the third number after the point which in this case is 7. So you check if it is greater than or equal to or less than 5. If it is greater than or equal to 5 you carry forward 1 to the next digit to the left which is 0 in this case which will give you 1, then you retrieve the number plus the first two decimals after the point to get 35.61(2d.p).

The inverse of a function [tex]f(x) = \sqrt{3x + 6}[/tex] is [tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex].
Here,
A function is given as, [tex]f(x) = \sqrt{3x + 6}[/tex]
We have to find the inverse of given function.
What is Inverse function?
An inverse function is a function that undoes the action of the another function.
Now,
A function is given as, [tex]f(x) = \sqrt{3x + 6}[/tex]
To find inverse function,
Replace f(x) by y in the equation,
[tex]y = \sqrt{3x + 6}[/tex]
[tex]y^{2} = 3x + 6\\y^{2} -6 = 3x \\x = \frac{y^{2} - 6\\}{3}[/tex]
Replace every x by a y and solve for y, we get;
[tex]y = \frac{x^{2} - 6\\}{3}[/tex]
Replace y by [tex]f^{-1} (x)[/tex], we get,
[tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex]
Hence, The inverse of a function [tex]f(x) = \sqrt{3x + 6}[/tex] is [tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex].

The denominator of a fraction is one more than the numerator. If 3 is subtracted to
the numerator and to the denominator, the resulting fraction is equivalent to 1 . What is the 2
original fraction?
Answer:
[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
let the original fraction be
[tex]\frac{n}{n+1}[/tex] ( with denominator 1 more than numerator )
Subtracting 3 from numerator/ denominator gives
[tex]\frac{n-3}{n+1-3}[/tex] = [tex]\frac{n-3}{n-2}[/tex]
Given that the fraction is now equivalent to [tex]\frac{1}{2}[/tex] , then
[tex]\frac{n-3}{n-2}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2(n - 3) = n - 2, distribute left side
2n - 6 = n - 2 ( subtract n from both sides )
n - 6 = - 2 ( add 6 to both sides )
n = 4
and n + 1 = 4 + 1 = 5
Thus original fraction is [tex]\frac{4}{5}[/tex]
