is 5 square root-2 square root rational?
5 square root - 2 square root is 0.821854415 and it is rational.
Given,
5 square root - 2 square root
That is,
√5 - √2
We have to find this is rational or not.
First we have to solve the equation:
√5 - √2 = 0.821854415
Irrational numbers cannot be stated as a fraction, although rational numbers can be expressed as ratios (such as P/Q and Q0). However, both of the numbers are genuine and can be shown on a number line.
So, here 0.821854415 is a rational number.
That is, 5 square root - 2 square root is rational.

What is the number rounded to 3 decimal placesA decimal is a number that is made up of integers and non-integers. The integers are separated from the non-integers by a decimal point.
In order to round off a number to 3 decimal places, there must be 2 numbers to the right of the decimal point.
In order to round off a number to 3 decimal places, if the ten thousandth figure is equal to five or greater than 5, one is added to the thousandth figure. If the ten thousandth figure is less than 5, there is no change in the thousandth digit.
The ten thousandth is greater than 9, so one is added to the thousandth digit. The number becomes 387. 870

Decimals into Fractions-
0.5 = 5/10
How to convert fractions into decimals and decimals into fractions ?Place the decimal number above its place value to convert it to a fraction.
For instance, since the number six is in the tenths place in the fraction 0.6, we multiply it by 10 and get the comparable fraction 6/10.
Simplify the fraction if necessary.
The division is shown by the fractional bar between the "part" and the "whole."
By dividing the numerator by the denominator, any fractions can be transformed into decimals.
For instance, the fraction 45 denotes the ratio of 4 to 5, or 4/5.
By dividing 4 by 5, this fraction can be changed into a decimal.

six tickets to a movie cost $76.50. What constant of proportionality relates the number of tickets and total cost?
The constant of proportionality is 12.75
The constant of proportionality is the ratio of the constant values of two proportional quantities.
Two changing values are said to be in proportion when either their ratio or product results in a constant. The proportionality constant's value is determined by the Direct Variation and Inverse Variation types of proportions between the two supplied values.The direct proportionality equation, y = kx, shows that when x increases, y increases at the same rate. As an illustration, y x stands for the cost per item(y), which is inversely related to the quantity of items(x) bought.The indirect proportionality equation, y = k/x, shows that when y increases, x decreases, and vice versa.The direct variation is given by y = k x where k is the constant of proportionality.
Now the cost of 6 tickets is $76.50
76.50 = k × 6
or, k = 12.75
Therefore the constant of proportionality is 12.75

The graph of y = 2x^2 - 8x + 7 is identical to the graph of y = a(x-h)^2 + k$ for some real numbers $a, h, k$.
What is the value of $k$?
The form:
y = a(x-h)^2 + k
Is the vertex form of the quadratic equation, by finding the vertex, we conclude that k = -1.
How to get the value of k?For any quadratic equation of the form:
y = a*x^2 + b*x + c
With a vertex (h, k), we can rewrite the equation as:
y = a*(x - h)^2 + k
And the value h of the vertex is given by:
h = -b/(2a)
In this case, the quadratic equation is:
y = 2x^2 - 8x + 7
Then the value h of the vertex is:
h = -(-8)/(2*2) = 2
Evaluating the quadratic equation in x = 2 we will get the value of k, so we have.
y = 2*(2)^2 - 8*2 + 7 = -1
Then the vertex is (2, -1), which means that the value of K is -1.

x+1 2/3 =2 3/8 what is x
Answer:
X=17/24
Step-by-step explanation:
first you need to find common denominators. To find it, you would multiply the denominator of the 1 2/3 and the 2 3/8.8*3=24, which means the denominator is 24. For 1 2/3, we multiplied 3*8 so we also have to do it for 2. The new equation is x+1 16/24=2 3/8. But remember, we still have to multiply 8*3, which means we have to multiply 3*3 too.
New equation:x+1 16/24=2 9/24
Now we can subtract 1 16/24 from each side

What is fraction in simplest form?When the numerator (top) and denominator (bottom) of the fraction do not have any common factors, the fraction is said to be in its simplest form. When the top and bottom of a fraction are whole numbers that are coprime to one another, the fraction is said to be in its simplest form.Any fraction can be easily found in its simplest form. By dividing both the numerator and denominator by the greatest common factor that entirely divides them, we need to simplify the fraction's numerator and denominator. Both the numerator and the denominator should still be whole numbers after division. Reducing fractions is another name for this process of simplifying fractions.Given fraction is [tex]5*4\frac{6}{11}[/tex].
So we convert the mixed fraction into an improper fraction to calculate further.
[tex]4\frac{6}{11} =\frac{50}{11}[/tex]
