The expression 2x²y has in its entirety 1 term.
First let's define what algebraic expressions are.
Algebraic expressionAn algebraic expression is a set of numbers and letters that make up an expression that has a meaning, the letters are variables and the numbers are coefficients or independent terms, algebraic expressions can be part of an equation and model mathematical processes.
The terms of an expression are identified by the fact that they are separated by means of an addition and subtraction operation:
x + y has two termsSince 2x²y has neither addition nor subtraction operations, we can clearly state that it has only one term.

Which measures describe the variation on a data set? a. Mean b. Median c. Mode d. MAD e. Interquartile range f. Range
Answer:
e, f
Step-by-step explanation:
A measurement of variability is an overview of the amount of dispersion in a dataset. The measures that can describe the variation on a data set are Range, Interquartile Range, Variance, and Standard Deviation.
So ,The among the given options the e. Interquartile range f. Range
Range of dataset is the difference between the larges and smallest elements in the dataset .
The middle of the data between the upper and lower quartiles are called the inter-quartile range. That means that 50 percent of data points between Q1 and Q3 are included within the interquartile range.
Find the measure of CGD.
Answer:
23°
Step-by-step explanation:
For this scenario say point G is the center point,
If we look to the left, we see angle FGE has a value of 23
and in this case angle CGD is a congruent angle to FGE therefore the two angles must be the same
so therefore angle CGD should be 23 degrees

Step-by-step explanation:
Remark
Is that a misshapen circle or is it an ellipse? I'm going to assume it is a circle, but if I am wrong, leave a comment. A tangent will meet a diameter's end at right angles which allows you to use the Pythagorean theorem.
Formula
a^2 + b^2 = c^2
Givens
c = 12
a = 9.6
b = ?
Solution
c^2 - a^2 = b^2
144 - 92.16 = b^2
b^2 = 51.84 Take the square root of both sides
sqrt(b^2) = sqrt(51.84)
b = 7.2

the roots of f(x)=-2x^2+8x+13 are __________and __________ the vertex of the parabola is at _________
Answer:
roots: 2 ± (1/2)√42
-8
axis of symmetry: x = -b/(2a) is x = ---------------- = 2
2(-2)
vertex: (2, f(2) ) = (2, -2(2)^2 + 8(2) + 13 ), or (2, 21)
Step-by-step explanation:
First, let's determine the roots of this quadratic, using the quadratic formula. Here the coefficients are -2, 8, 13.
Thus, the discriminant b^2 - 4ac is 8^2 - 4(-2)(13), or 64 + 104, or 168. Because the discriminant is positive, we know that there are two different real roots.
They are:
-8 ± √168 -8 ± 2√42
x = --------------------- or x = --------------------- = 2 ± (1/2)√42

Given the arithmetic sequence where an= 3 + 2(n-1), what is the domain for n?
Answer:
The set of all positive integers equal to or greater than 1
Step-by-step explanation:
n can take on the integer values 1 ... ∞
The formula for the nth term is a(n) = a(1) + 2(n - 1)
First term: n = 1. Then a(1) = 3 + 2(0) = 3 (as expected).
5th term: n = 5. Then a(5) = 3 + 2(5 - 1) = 3 + 8 = 11
...
and so on.

If using the method of completing the square to solve the quadratic
equation x2 + 20x – 6 = 0, which number would have to be
added to "complete the square"?
Answer:
100
Step-by-step explanation:
20/2= 10 and 10 squared is 100 but you have to move the -6 to the opposite side
The number required to add to the equation x² + 20x - 6 is 106
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A = x² + 20x - 6 = 0
Now , to make the equation as a perfect square,
The number to be added to the equation is 106
Adding 106 to the equation , we get
A = x² + 20x - 6 + 106
On simplifying the equation , we get
A = x² + 20x +100
Now , the equation can be factorized as
A = ( x + 10 )²
A = 0
( x + 10 )² = 0
x = -10
Hence , The number required to add to the equation x² + 20x - 6 is 106 to make it a perfect square

A ball inside of a cube has a volume of 524 cubic inches. If each side of the cube measures 12.75 inches. what is the volume of air inside the cube? (Round to the nearest tenth.)
1) 1548.7 cubic inches
2) 2072.7 cubic inches
3) 2596.7 cubic inches
4) 1048.0 cubic inches
Answer:
1548.7 in³
Step-by-step explanation:
Given that :
Volume of ball = 524 in³
Volume of a cube = s³
Where, s = 12.75 inches
Volume of cube = 12.75 * 12.75 * 12.75 = 2072.671875 in³
The volume of air inside the cube :
(volume of cube - volume of ball)
(2072.671875 - 524) in³
= 1548.671875 in³
= 1548.7 in³ (nearest tenth)

If 27 ×32 = 3x×2y;find the values of x and y
Answer:
Step-by-step explanation:
hello :
27 ×32 = 3x×2y
means : 27 ×32 = 6xy
xy= (27 ×32)/6
xy = 144
but : 144 =12² = (4×3)²=(2²×3)²
144=2^4 ×3²
so : xy = 2^4 ×3²

I have to find the missing angles
Answer:
Angle 3 = 115°
Angle 4 = 22°
Angle 5 = 43°
Angle 6 = 115°
Step-by-step explanation:
These two triangles are congruent by SSS. It is given that two sides are congruent already, and by the reflexive property, they share a side and therefore have a third congruent side.
By CPCTC, all of their angles and sides are also congruent. And by the triangles angle sum theorem, side 3 and 6 must equal 115°
~~~
Have a nice day. Feel Free to ask questions. Spread the love.
Step-by-step explanation:
4 = 22⁰
5 = 43⁰
3 and 6 are same
kite total angles = 360⁰
so, to find 3 and 6, we need to subtract all angles we have and devide it with 2 because we need to find 2 angles...
360-22-22-43-43= 230
3 and 6 = 230 ÷ 2
= 115⁰
Sam's two new aquariums each hold exactly 200 gallons of water.One aquarium will hold small fish and the other will hold large fish. Now he needs new fish for his aquarium.He will buy 5 small fish for every 10 gallons of water in the aquarium.He will buy 8 large fish for every 40 gallons of water in the aquarium.What is the total number of fish Sam will have? What will be the ratio of Sam's small fish to large fish? Could the ration be 25 small fish for every 10 big fish?
Answer:
100 small fish will be in 200 gallons of water. 40 large fish will be in 200 gallons of water.
Step-by-step explanation:
200/10=20
20*5=100 small fish
200/40=5
5*8=40 large fish
100+40=140 total fish
small fish/large fish=100/40=10/4=5/2 is the ratio

Parts of a Division Problem -There are three main parts to a division problem: the dividend, the divisor, and the quotient. The dividend is the number that will be divided. The divisor is the number of “people” that the number is being divided among. The quotient is the answer.Let us assume that the number is N.
So according to the question we can say that
N= 15(18) +1
because dividend= divisor x (quotient) + remainder and quotient is odd.
So now, N (on expanding) =15 × 18 + 5
= 275
So if N is divided by 15 the remainder would be 275+1=276.

The constant of proportionality of 100 cm in 1 meter is 0.01
How to determine the constant of proportionality?The statement is given as:
100 cm in 1 meter
Rewrite as:
x cm in y m
Express as ratio
100 : 1 = x : y
Express as fraction
100/1 = x/y
Divide
100 = x/y
Make y the subject
y = x/100
Divide
y = 0.01x
A direct proportion is represented as y = kx
Where k represents the constant of proportionality.
So, we have:
k = 0.01
