which of these is not included in the set of rational numbers? all integers, all whole numbers, all repeating decimals, or all non-terminating decimals
Answer: non-terminating decimals
Integers and whole numbers can be converted to fraction form. Example, the whole number 3 can be written as 3/1 which is rational. A rational number is any fraction of whole numbers (eg: 7/19). The denominator can never be zero.
All repeating decimals can be converted into a fraction. A number like 0.8888 with the 8s repeating forever converts to the fraction 8/9, which is rational
Non-terminating decimals are decimals that go on forever. If there is no pattern to the decimal sequence, then the decimals don't repeat and the number cannot be converted to a rational number. Something like pi = 3.14159... has no pattern to the decimal sequence. Therefore, a number like pi is irrational, which literally means "not rational", so numbers like pi aren't rational and are not part of the set of rational numbers.
Non terminating and non repeating decimals cannot be written in fraction from . So they are not included in set of rational numbers.

a woman has $28,000. part is invested for one year in a certificate of deposit paying 7% interest, and the remaining amount in cash management fund paying 9%. after 1 year, the total interest on the two investments is $2,200. how much is invested at each rate
Answer:
Amount invested at 7% = 16000
Amount invested at 9% = 12000
Step-by-step explanation:
Let x be the amount invested at 7% and y be the amount invested at 9%.
Since the total amount invested is $28000, therefore, we can set up the first equation as:
[tex]x+y=28000[/tex]
Secondly, we are give that sum of two investments is $2200. Therefore, we can write the second equation as:
[tex]0.07x+0.09y=2200[/tex]
Now we need to solve these two equations to get the values of x and y.
First of all, we multiply the second equation with 100 in order to get rid of decimal values.
[tex](0.07x+0.09y)*100=2200*100\\7x+9y=220000[/tex]
Let us use substitution method here. First of all we will solve for y from first equation and plug that into second equation.
[tex]y=28000-x[/tex]
[tex]7x+9(28000-x)=220000\\7x+252000-9x=220000\\-2x=-32000\\x=16000[/tex]
Therefore, amount invested at 7% is $16000 and amount invested at 9% is 28000-16000=$12000.

The given triangle has two sides marked equal and hence is an isosceles triangle.In isosceles triangle base angles are equal <A=<B=50.
Sum of angles in any triangle is 180 degrees.
<A+<B+<C=180°
50+50+5y+10=180
Adding like terms :
110+5y=180
Subtracting 110 on both sides:
5y=70
Dividing both sides by 5:
y=14.
The isosceles triangle, with base angles both at 50 degrees, is solved for the variable y, resulting in y = 14. This value, when substituted, gives angle C as 65 degrees.
The triangle in question is an isosceles triangle, meaning that two of its sides are of equal length. Consequently, the base angles, denoted as angle A and angle B, are also equal, and both are given as 50 degrees. In any triangle, the sum of its angles equals 180 degrees, so for this isosceles triangle:
[tex]\[ \angle A + \angle B + \angle C = 180^\circ \][/tex]
Substituting the known values:
50 + 50 + 5y + 10 = 180
Combining like terms:
110 + 5y = 180
To isolate the variable term, subtract 110 from both sides:
5y = 70
Now, divide both sides by 5 to find the value of y:
y = 14
In conclusion, the value of y is determined to be 14. This signifies that in the given isosceles triangle, angle C is represented as 5y + 10, which becomes 65 degrees. Therefore, the solution provides a comprehensive understanding of the triangle's angle distribution.

You have to make an assumption here. I know of no other way to do the problem than by making the assumption that 10 * 14 figure is a rectangle. If that is not true, the problem is not solvable.
Step One
Find the length of the shaded area.
The length will be the length of the hypotenuse of a right triangle formed by the two smaller sides = the hypotenuse.
a = 4
b = 12
c = ????
Length
L = square root (a^2 + b^2)
L = √(4^2 + 12^2)
L = √(16 + 144)
L = √160 = √(4*4 * 10)
L = 4√(10)
Width
The width is done the same way.
a = 6
b = 2
w = c = ??
w = √(6^2 + 2^2)
w = √(36 + 4)
w = √40
w = √(2 * 2 * 10)
w = 2 √ 10
Area
Area = L * W
Area = 4√10 * 2√10
Area = 8 * 10

Is it true that to finding the LCM you have to divide the product but he GCF? If not give in example why not, and if it’s true, why does it work?
To find the LCM, you CAN divide the product of the two numbers by the GCF.
This is not a very well-known fact, but it is useful at times, especially when we are asked to calculate both the LCM and GCF.
For example, the GCF of 18 and 48 is 6, by inspection or by factors.
Therefore the LCM of 18 and 48 is 18*48/6=864/6=144.
It works because by definition the GCF is the products of all common factors between the two given numbers. Dividing the product by the GCF will therefore remove the duplication of the common factors, leaving a number which contains the factors of each of the two numbers, thus a lowest common multiple.
Note that this method is not the only way to find LCM's.

Divide x^3 -3x^2 by x-2
. Step 1 - Fill in the missing number:
To divide x^3 - 3x^2 by x - 2, use long division. The quotient is x^2 - x - 4.
Explanation:To divide x^3 - 3x^2 by x - 2, we can use long division. Here are the steps:
Start by dividing the first term of the numerator, x^3, by the denominator, x. This gives us x^2.Multiply the entire denominator, x - 2, by the quotient we found in the previous step, x^2. This gives us x^2(x - 2) which simplifies to x^3 - 2x^2.Subtract this product from the numerator, x^3 - 3x^2 - (x^3 - 2x^2) = -x^2.Bring down the next term from the numerator, which is 0x.Divide this new term, -x^2, by the denominator, x, to get -x.Multiply the entire denominator, x - 2, by the quotient we found in the previous step, -x. This gives us -x(x - 2) which simplifies to -x^2 + 2x.Subtract this product from the previous result, -x^2 - (-x^2 + 2x) = -4x.Bring down the final term from the numerator, which is -6x^2.Divide this term, -4x, by the denominator, x, to get -4.Multiply the entire denominator, x - 2, by the quotient we found in the previous step, -4. This gives us -4(x - 2) which simplifies to -4x + 8.Subtract this product from the previous result, -4x - (-4x + 8) = -8.Therefore, the quotient of x^3 - 3x^2 divided by x - 2 is x^2 - x - 4.
