How many subsets are there in A={x:x is letters of the alphabet}

Answer:

For each coin he has 6 dimes, 12 quarters, and 9 pennies.

Answer:

7

Step-by-step explanation:

[tex]2 \times p \times q - r\\= 2 \times 3 \times 2 - 5\\= 2 \times 3\\= 6\\= 6 \times 2\\= 12\\= 12 - 5\\= 7[/tex]

       The range is all the y-value or outputs of a function. In the case of a horizontal line, this is only one value.

               The range is the y-intercept, -5.

       The domain is all x-values or inputs of a function. For this graph, it is all real numbers (as you said).

               The domain is all real numbers.

Answer:

A. 5,420

Step-by-step explanation:

4 in 542 is in the tens place and 4 in 5,420 is in the hundreds.

The number A. 5420 has a 4 that is 10 times greater than the 4 in 542.

The standard decimal form of numbers is written in base 10 as there are 10 different numbers from 0 to 9.

Each digit has a face value and a place value.

The expanded form of 542 is 5×100 + 4×10 + 4.

So, 10 times greater than it should be a multiple of 100 or a digit in the hundreds place.

From the given options the number 5420 in the expanded form is,

5×1000 + 4×100 + 2×10 + 0.

So, The number 5420 has a 4 that is 10 times greater than the 4 in 542.

Effective Annual Yield : 10.5%

Effective Annual Yield

​ In the case of monthly  there are 12 months in a year. Therefore, making n=12. So, the effective annual yield if the interest 10% is compounded monthly is given as r=10, n=12;

           [tex]Y= (1 +\frac{r}{n}) ^{n}-1 = (1 +\frac{0.1}{12}) ^{12}-1\\ =(1 +0.00833) ^{12}-1\\ =(1.00833) ^{12}-1\\ = 1.10466 -1\\ = 0.10466[/tex]

   But, this is decimal form, to convert it to the percentage form we have to multiply the decimal form by 100 and finally, place "%" after the last digit of the number. That is,

                                       Y= 0.10466× 100%

                                       Y=10.46% or 10.5%

The length of all four sides of the Isoclesles Trapezium is 67 inches.

Area of a Trapezium is (1/2)(a+b)h.Where and b are the parallel sides of the trapezium and h is the distance between the two parallel side

We know that for a plane 2D figure perimeter is the sum of the lengths of all the sides.

Given an isosceles Trapezium with a perimeter of 67 inches,

As the sides are given in variables we can equate the sum of all the sides with the given perimeter and obtain the value of x.

∴ (x + 1.5x + 2.5x - 5 + x) = 67.

6x = 67 + 5.

6x = 72.

x = 12.

So, the measure of lengths of four sides are [ 12 + 1.5(12) + 2.5(12) - 5 + 12) which is ( 12 + 18 + 30 - 5 + 12 ) = 67 inches.

The Remaining length of the cardboard piece is  94.15 cm.

According to the statement

We have to find that the length of the remaining piece.

So, For this purpose, we know that the

Length is defined as the measurement or extent of something from end to end.

From the given information:

Four pieces measuring 29.cm, 19.62cm, 32.49cm and 24.74cm are cut from a board that is 200cm long.

Then

Total length of the four pieces become:

Four pieces length = 29+19.62+ 32.49 + 24.74

Four pieces length = 105.85 cm

Then the

Remaining length of the cardboard piece = total length - length of the four pieces.

Remaining length of the cardboard piece = 200 - 105.85

Remaining length of the cardboard piece = 94.15cm.

So, The Remaining length of the cardboard piece is  94.15 cm.

The points which are a distance of 13 units from (12,5) are (0,0)and (24,0).

The distance between two point with co-ordinates ([tex]x_1,y_1[/tex])  and ([tex]x_2,y_2[/tex]) is calculated by the distance formula [tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

All points on the x-axis have their y-coordinates equal to 0. So let the point (a,0) be a point on the x-axis such that the distance from (12,5) to (a,0) is 13 units.

Let us substitute the values into the distance formula to calculate the values of a so that we can find the two points.

[tex]13=\sqrt{(12-a)^2+(5-0)^2}[/tex]

Squaring both sides we get:

[tex]or,13^2=144-24a+a^2+25\\or,169-144-25-24a+a^2\\or,a^2-24a=0\\or,a(a-24)=0[/tex]

The value of x is 64 and the property that justifies that action is  the multiplication property of equality.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

Mathematical statements are called expressions if they contain at least two terms that are connected by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.

As an illustration, the expression x + y is one where x and y are terms with an addition operator in between. There are two types of expressions in mathematics: numerical expressions, which only contain numbers, and algebraic expressions, which also include variables.

We have an expression:

x/4 = 16

Apply Multiplication property of equality:

Multiply by 4 on both sides:

(x/4)4 = 16×4

x = 64

Answer:

Step-by-step explanation:

Given the quadratic equation y = 2x² +7x -9, you want the coordinates of the x- and y-intercepts.

The values of x where y=0 can be found by factoring the equation.

  y = (2x +9)(2x -2)/2 = (2x +9)(x -1)

The constants 9 and -2 in the binomial terms are factors of the product of leading and trailing coefficients (2)(-9) = -18. Those factors are chosen because their sum is 7, the middle coefficient.

The x-intercepts are the values of x that make these factors zero:

  2x +9 = 0   ⇒   x = -9/2

  x -1 = 0   ⇒   x = 1
