The number of batches of cookies required for your dad to bake is 6.33 batches.

Number of people at the party = 38

Number of cookies each would have = 4

Total number of cookies needed = Number of people at the party × Number of cookies each would have

= 152 cookies

Number of cookies baked per batch = 24

Equate the number of batches to the number of cookies baked.

Let x = number of batches required

1 : 24 = x : 152

1/24 = x / 152

cross product

1 × 152 = 24 × x

152 = 24x

divide both sides by 24

x = 152 / 24

x = 6.33 batches

Therefore, your dad should bake 6.33 batches of cookies for everyone at the party.

Answer: B. 12cm^2.

Step-by-step explanation:

To find the area of the shape, you need to count the number of squares inside it and then multiply that number by the area of a single square. If each grey square is 1cm by 1cm, then the area of a single square is 1cm x 1cm = 1cm^2. If you count the squares inside the shape, you will see that there are 12 squares. Therefore, the total area of the shape is 12cm^2. The correct answer is therefore B. 12cm^2.

Statement: 5(x+6)=x+38 is x=2

We are given the equation 5(x+6)=x+38. We can solve this equation by isolating x on one side of the equation. To do this, we will first subtract x from both sides of the equation. This will leave us with 5x+30=38. We can then subtract 30 from both sides of the equation to isolate the x terms. This leaves us with 5x=8. We can then divide both sides of the equation by 5 to isolate x. This gives us x=2.

Therefore, if 5(x+6)=x+38, then x=2.

The Given Statement is  true reason is the value in the left-hand side is equal to the value in the right-hand side. it shows proof that 5(x+6) = x+38 for x =2.

Here we have to understand what is an equation because in question we have given an equation.

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13.

2x - 5 and 13 are expressions in this case.

These two expressions are joined together by the sign "=".

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. Since we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

Here we have given an equation

5(x+6) = x+38  we have to proof for x = 2.

LHS 5(x+6) = 5(2+6) = 5*8 = 40

RHS x+38 = 2+38 = 40

So the given statement is true because LHS = RHS.

The reasons for each statement about the given triangle are as follows:

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.

Given, A triangle PWZ in that base ∠1 and ∠2 are same and the distance between W and Z from X and Y are the same where XY is the base of another triangle inside the ΔPWZ.

For ΔPWZ

We know PWZ is an isosceles triangle since its two angles are the same.

thus another ΔPXY is on the same base of ΔPWZ and also at the same distance from its point Hence, these triangles are congruent triangles.

Looking at that perspective, we can say that ∠1 and ∠2 are pairs of alternate angles and are congruent.

∠1 ≅ ∠2

The same with ∠3 and ∠4.

∠3 ≅ ∠4

Therefore, As a result, according to the ASA Theorem, the Triangles are congruent. The two angles and the side they encompass are comparable.

The local linear approximation of f(x) 2In(x) at x = 2 is y = x - 2 + log (4).

As per the given data, the function f(x) is given by:

f(x)=2 log (x) at x = 2

Here we have to determine the linear approximation of f(x).

A linear approximation is a mathematical phrase that describes using a linear function to approximate a general function.

We know the linear form of the function is

y = f(a) + f'(a) ( x - a )

Here, a = 2

Therefore y = f(2) + f'(2) (x - 2) . . . (1)

Now, f(2) = 2 log (2)

= log [tex](2)^2[/tex]

= log (4)

Again, f'(x) =[tex]\frac{d}{d x}[f(x)][/tex]

[tex]=\frac{d}{d x}(2 \log (x)) \\[/tex]

f'(x) = [tex]2 \cdot \frac{1}{x}=\frac{2}{x} \\[/tex]

Therefore f'(2) = [tex]\frac{2}{2}[/tex] = 1

Plug in the values of f(2) and f'(2) in equation (1) we get,

y = log (4) + 1(x - 2)

y = x - 2 + log (4) (which is the linear approximation of f(x))

Therefore option (b) is correct

You can form two different types of quadrilaterals from the given sticks of 8cm,8cm,5cm,5cm.

A quadrilateral is a polygon with four sides and four angles. Quadrilaterals are two-dimensional shapes, meaning they exist on a flat surface and have length and width, but no depth. Some examples of quadrilaterals include rectangles, squares, parallelograms, and trapezoids.

You can form two different types of quadrilaterals using four sticks of 8cm, 8cm, 5cm, and 5cm in length such as a rectangle of the two 8cm sticks as the length and the two 5cm sticks as the width to create a rectangle, and you can also form a parallelogram by using the two 8cm sticks as the length, and the other two 5cm sticks as the width.

The solution to the equation 3 x 2 − 12 d − 2 is 1/3.

Solving the equation for d because the value of d would be the required solution to this equation:

Now

 3 x 2 − 12 d − 2  = 0

  6     -  12 d   - 2  =  0

Sitting the constant terms to the right side of the equation while keeping the term with d to the left-hand side of the equation:

A: The composite function that represents the number of U.S. dollars equivalent to x British pounds is 1.54x

B: An item that costs 15 British pounds is equivalent to 23.10 U.S. dollars.

What is the composite function?

A composite function is a function that is formed by the composition of two or more functions. It is a new function that is made by plugging the output of one function into another function. The notation for a composite function is f(g(x)) or f(g), where f and g are the two functions being composed.

a. To write a composite function that represents the number of U.S. dollars equivalent to x British pounds, we want to substitute the output of f(x) into g(y). So, we want to find g(f(x))

g(f(x)) = g(9.09x) = 0.17(9.09x) = 1.54x

So, the composite function that represents the number of U.S. dollars equivalent to x British pounds is 1.54x

b. To find the value in U.S. dollars of an item that costs 15 British pounds, we substitute x = 15 into the composite function:

1.54(15) = 23.10

So, an item that costs 15 British pounds is equivalent to 23.10 U.S. dollars.

Using the diameter given, the volume of the sphere is 14137.17cm³

The volume of a sphere is a measurement of how much space it takes up. It is calculated using the following formula and represents the volume of the sphere:

v = 4/3 * π * r³

Where: r is the radius of the sphere, which is the distance from the sphere's center to its surface, and π is a mathematical constant roughly equal to 3.14.

The formula is based on the observation that a sphere's volume is two thirds that of a cylinder with the same radius and height.

The volume of a sphere is directly proportional to the cube of the radius, which is a crucial point to remember.

In the problem, the diameter given is 30cm, we can calculate the radius from this.

radius = diameter / 2

radius = 30 / 2

radius = 15cm

We can plug in the values to calculate the volume of this sphere;

v = 4/3πr³

v = 4/3(3.14)(15)³

v = 14137.17cm³

The volume is 14137.17cm³

There are 30 students in the Maths class, 30 students in the English class and 40 students in the history class using Gauss-Jordan elimination to solve the system of equations.

We shall derive and solve the system of equations as follows:

homework questions corrected per week;

10x + 20y + 30z = 2100...(1)

number of homework papers corrected per week;

x + y + z = 100...(2)

x = number of students in the math class

y = number of students in the English class

z = number of students in the history class.

since the maths and English classes have the same number of students then x = y and: equations (1) and (2) becomes;

10x + 20x + 30z = 2100

30x + 30z = 2100

30(x + z) = 2100 {divide through by 30}

x + z = 70...(3)

x + x + z = 100

2x + z = 100...(4)

Subtract equation (3) from (4) to eliminate z

2x + z - x - z = 100 - 70

x = 30

Now we will substitute this value of x back into the equation (4) such that;

2(30) + z = 100

60 + z = 100

z = 100 - 30 {subtract 60 from both sides}

z = 40

So there are 30 students in the Maths class, 30 students in the English class and 40 students in the history class using Gauss-Jordan elimination to solve the system of equations.
