Rationalise the denominator and simplify 6/√3
⇛2√3.
Step-by-step explanation:
Given,
6/√3
The denominator is √3.
We know that
The rationalising factor of √a is √a. To rationalise the denominator of 6√√3, we multiply this by √3/√3.
⇛(6/√3)×(√3/√3)
⇛(6√3)/(√3)²
⇛(6√3)/(√3*3)
⇛(6√3)/3
⇛2√3
Hence, the denominator is rationalised.

At the amusement park, the Ferris wheel is located 95 feet east and 156 feet north of the entrance. The swings are located 23 feet west and 124 feet north of the entrance. If Jalen is standing exactly three-eights the distance from the Ferris wheel to the swings, to the nearest hundredth of a foot, find the direct distance between Jalen and the entrance.
Answer:
113.18
Step-by-step explanation:
[tex]\sqrt{113^{2}+32x^{2}[/tex]
SF=113.18
The direct distance between Jalen and the entrance is 144.6 feet.
What is distance?The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Given:
Place everything on an xy grid with the Entrance at (0,0).
Then the Ferris Wheel is at (95,156) and the Swings are at (-23,124).
Cody is halfway between them,
so he is at
(95-((95-(-23)/2)),156-(156-124/2) or (36,140).
The distance from Cody to the entrance, using Pythagoras, is square root of
(362+1402)
=144.6 feet
Therefore , the direct distance between Jalen and the entrance is 144.6 feet.

I have a bag containing red, green, blue, and white marbles and the ratio $\text{red}:\text{green}:\text{blue}:\text{white}$ is $2:2:5:7$. I have 304 marbles. How many blue marbles do I have?
Answer:
95
Step-by-step explanation:
Let 2x be how many red/green marbles there are,
let 5x be how many blue marbles there are, and
let 7x be how many white marbles there are.
2x + 2x + 5x + 7x = 304
16x = 304
x = 19
As 5x is defined as how many blue marbles there are, we could just plug x for 19:
5*19 = 95
I hope this helped, and if it did please consider giving me brainliest :)
Answer:
95
Step-by-step explanation:
Let r, g, b, w be the number of red, green, blue, and white marbles, respectively. Since r : g : b : w = 2 : 2 : 5 : 7, there is some value of x for which r = 2 x, g = 2x, b = 5x, and w = 7x. Then, we have
304 = r + g + b + w
= (2x) + (2x) + (5x) + (7x)
= 16x
Dividing both sides of 16x = 304 by 16 gives x=19. This gives us r = 38, g = 38, b = 95, w = 133, so I have 95 blue marbles.

What is the measure of the angles below?* 8x-3 6.x + 17
Answer:
x = 10
Step-by-step explanation:
Simplifying
8x + -3 = 6x + 17
Reorder the terms:
-3 + 8x = 6x + 17
Reorder the terms:
-3 + 8x = 17 + 6x
Solving
-3 + 8x = 17 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-3 + 8x + -6x = 17 + 6x + -6x
Combine like terms: 8x + -6x = 2x
-3 + 2x = 17 + 6x + -6x
Combine like terms: 6x + -6x = 0
-3 + 2x = 17 + 0
-3 + 2x = 17
Add '3' to each side of the equation.
-3 + 3 + 2x = 17 + 3
Combine like terms: -3 + 3 = 0
0 + 2x = 17 + 3
2x = 17 + 3
Combine like terms: 17 + 3 = 20
2x = 20
Divide each side by '2'.
x = 10
Simplifying
x = 10

A postal carrier delivers mail to 20 mailboxes on one side of a long street. Beginning with the first mailbox, the carrrier takes 5 seconds to sort and put the mail in each mailbox, and the mailboxes are 100 feet apart. How fast (in feet per second) must the carrier walk in order to complete delivery to all 20 mailboxes in 10 minutes? Answer in decimal form as a.b (for example, 9.7).
Answer:
3.8 seconds
Step-by-step explanation:
Time taken to sort the mail is [tex]5[/tex] seconds
Let time taken to go from one mailbox to the next be [tex]x[/tex]
Distance between the mailboxes is [tex]100[/tex] ft
So, sorting the mail for one mailbox and going to the next will be done in [tex](5+x)[/tex] seconds
This will happen 19 times and 5 seconds will be needed to sort the mail for the last mail box. The carrier will have to deliver to all the 20 mailboxes in 10 minutes. So, the total time taken will be
[tex]19(5+x)+5=10\times 60\\\Rightarrow 19(5+x)=595\\\Rightarrow 5+x=\dfrac{595}{19}\\\Rightarrow x=\dfrac{595}{19}-5\\\Rightarrow x=\dfrac{500}{19}\ \text{s}[/tex]
Time taken to go from one mailbox to the other is [tex]\dfrac{500}{19}\ \text{s}[/tex]
Speed is given by
[tex]v=\dfrac{100}{\dfrac{500}{19}}\\\Rightarrow v=3.8\ \text{ft/s}[/tex]
The speed at which the carrier has to move from one mailbox to the next is 3.8 seconds.

A dime is what fraction of a dollar?
Answer:
1/10
Step-by-step explanation:
A dime is 1/10 fraction of a dollar.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator. Any number can be expressed as fractions.
We have to convert a dime into a fraction of a dollar.
Number of dimes in a dollar = 10
10 dimes = 1 dollar
1 dime = 1/10 dollar
So we can say that one dime is 1/10 of a dollar.
Hence 1/10 fraction of a dollar is 1 dime.

Determine the solution.
2x+y=4
4x-3y=7
Answer:
The answer is: (x , y) = (19/10 , 1/5)
Step-by-step explanation:
Solve the equation for y-
y = 4 - 2x
4x - 3y = 7
Substitute the given value of y into the equation-
4 x - 3 ( 4 - 2x ) = 7
Solve the equation for x-
x = 19/10
Substitute the given value of x into the equation y = 4 - 2x-
y= 4 - 2 * 19/10
Solve the equation for y-
y = 1/5
The possible solution of the system is the ordered pair ( x , y )-
( x , y ) = ( 19/10 , 1/5)
Check if the given ordered pair is the solution of the system of equations-
{2 * 19/10 + 1/5 =4
4 * 19/10 - 3*1/5 =7}
Simplify the equalities-
4 = 4
7 = 7
Since all equalities are proven true the ordered pair is the solution of the system-
( x , y) = (19/10, 1/5)
FINALLY haha the solution is: ( x , y ) = (19/10 , 1/5)

Answer
It is possible to find f(x+7) by replacing each occurrence of
X by X+7
It is possible to find f(x+7) by replacing each occurrence of x in the function f(x) = x² - 5x + 4 and the function f(x + 4) becomes f(x + 4) = x² +3x.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
f(x) = x² - 5x + 4
It is required to find the f(x + 4)
Replace x with x + 4
f(x + 4) = (x + 4)² - 5(x + 4) + 4
f(x + 4) = x² + 8x + 16 - 5x - 20 + 4
f(x + 4) = x² +3x
The function f(x + 4) is f(x + 4) = x² +3x after plugging x = x + 4 in the f(x)
Thus, it is possible to find f(x+7) by replacing each occurrence of x in the function f(x) = x² - 5x + 4 and the function f(x + 4) becomes f(x + 4) = x² +3x.

Answer:
- Opposite angles are congruent (equal).
- Parallelograms have 4 sides
- Opposites sides are parallel and equal in length.
Step-by-step explanation:
A parallelogram is a quadrilateral and since quadrilaterals are fur sided figures, hence parallelograms are also four sided figures.
A parallelogram has its opposite side equal and parallel to each other with a slanting edge at two of its sides. Since its opposite sides are equal hence its opposite angles are also equal.
Parallelogram cannot have more than four sides because they are quadrilateral. Find the diagram of a parallelogram in the attached figure.
