9.The area of a trapezoid is given as;

A={1/2h{b2 +b2}} where b2 and b2 are the lengths of the sides and h is the height

To express b2 in terms of A ,h, and b2 will be to make b2 the subject of the formular of trapezoid area.This will be

A={1/2h{b2 +b2}} ------ collect like terms and add

A={1/2h{2b2}} --------cancel the 2 in the 1/2 and that in brackets to get

A={h{b2}}

Divide both sides by h to remain with b2 on the right-hand side as

A/h = b2

So the expression will be :

b2 = A/h ---------answer

B = number multiplier

n = natural number

A = base number, interest number

In our case, the following procedure is followed:

Base number = Multiples between 1 and 200.

We know that 1 ton is the same as 2000 pounds. Then we have:

Given that Eleanor can run 300 meters in 85 seconds;

We want to calculate how many meters it can run in 395 seconds;

substituting;

Therefore, the distance they can run in 395 seconds is;

Since these triangles are similar, we can express the ratios of their sides like this:

By taking the first two ratios replacing the known values and then solving for YZ, we get:

The length of NZ is the length of YZ minus the length of YN:

NZ=YZ-YN=6-3=3

Then, NZ equals 3

By taking the last two ratios we can calculate XZ, like this:

Then, XZ equals 12

First, we find the inverse

Then, we solve for x = 1, 2, 3, 4.

Yes, the ordered pair (4, 7) is a solution of the equation y = 5x - 13.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

To conclude if the ordered pair (4, 7) is a solution of the equation

y = 5x - 13  or not we have to substitute the value of x and check what is the corresponding y value.

So, y = 5x - 13.

At x = 5,

y = 5(4) - 13.

y = 20 - 13.

y = 7.

∴ When x = 4 the corresponding y value is 7 so the given ordered pair

(4, 7) satisfies this condition.

Answer:

Whole numbers

Explanation:

The domain of a function is the set of all the possible values that the variable x can take. In this case, x represents the number of Chromebooks, so x can take values like 0, 1, 2, 3, ...

Therefore, the c(x) domain is the set of whole numbers because these are the numbers that we use to count.

The values of the angles are m∠AOB = 27°, m∠BOC = 48° and m∠COD = 27°.

Congruency may be defined as the property between two shapes or figures which shows same behavior in their shape and size. The symbol for congruency is given by '≅'. If one image is mirror image of another, then also both are said to be congruent. From the figure ∠AOB is congruent to ∠COD. We have the value of m∠AOB = 6x - 3 and m∠COD = 3x + 12. Equating these two values we get

6x - 3 = 3x + 12

3x = 15

=> x = 5

Now, the value of m∠AOB = 6x - 3 = 27°, value of m∠BOC = 6x + 18 = 48° and of value m∠COD = 3x + 12 = 27°.

Final answer: the required value of x is 6.

The evaluation of the equation will be 10x²y-5xy²+17216 where x,y⊆W; W stands for whole number.

Equations are mathematical statements that contain two algebraic expressions on both sides of an equal sign (=). It depicts the equality relationship between the expression written on the left side and the expression written on the right side. L.H.S = R.H.S (left hand side = right hand side) appears in every mathematical equation. Equations can be used to calculate the value of an unknown variable that represents an unknown quantity. If the statement lacks the 'equal to' symbol, it is not an equation. It will be treated as an expression. In the following section, you will learn the distinction between equation and expression.

You must substitute a number for each variable and perform arithmetic operations to evaluate an algebraic expression. Because 6 + 6 = 12, the variable x in the preceding example is equal to 6. We can evaluate the expression after replacing the variables with their values if we know their values.

For the given equation,

5xy(2x-y)+617(22+6)

open the brackets,

10x²y-5xy²+17216

This is the required equation.

The equation will be evaluated as 10x²y-5xy²+17216 where x,y⊆W; W stands for whole number.

Take into account that in a general way, a parabola can be written as follow:

y = a(x - h)^2 + k

where,

a: is the leadding coefficient

(h,k): vertex of the parabola

In order to graph the parabola, first calculate the value of a, by using the following information:

(h,k) = (0,-2)

(x,y) = (5,8)

Replace the previous values into the equation of the parabola and solve for a:

Then, the equation of the given parabola is:

The option that is true after the transformation is that; D) The segments share an endpoint.

Usually when we rotate a line segment about the origin in a clockwise manner, we will discover that the transformation rule is;

(x, y) = (y, -x)

Now, in this case it is not about the origin but about the point C and as such the coordinate C will not change after rotation as only the coordinate D will have a change in coordinate.

The coordinates of C and D originally are C(3,1) and D(7,4) .

Thus, the new coordinate of D will be;

D' (−(y − b) + a, (x − a) + b)

D'( (−(4 − 1) + 3, (7 − 3) + 1)

= D'(0, 5)

Using distance coordinate formula which is;

d = √((y₂ - y₁)²+ (x₂ - x₁)²)

where;

(x₁, y₁) is the coordinate of the first point on the line

(x₂, y₂)

CD = √((7 - 3)²+ (4 - 1)²)

Answer:

[tex]\frac{2}{sizes}[/tex] * [tex]\frac{18}{flavors}[/tex] *[tex]\frac{12}{toppings}[/tex] = 432 possible sundaes

Step-by-step explanation:

The required number of combinations Dontrelle can order is 504.

As mentioned in the question that 21 choices basic sundae comes in three sizes small medium or large and includes one flavor of ice cream and one of 12 toppings Dontrelle has enough money for a small or medium basic sundae.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

Here,
Total number of choices of sundaes = 21 small + 21 medium = 42
Total number of toppings = 12
Total ice cream = 1
Total number of combinations = 42 × 12 × 1 = 504

Thus, the required number of combinations Dontrelle can order is 504.
