what is fraction?

Mathematically speaking, fractions are represented by integers that indicate a portion of a whole. In the same way that a whole can be any quantity, value, or object, a fraction can be a portion or subset of any quantity of a whole. As an example, let's try to comprehend this idea. The pizza in the picture below is cut into 8 equally sized pieces. The chosen slice of pizza might now be expressed as 1/8 if we wanted to. This indicates that we are talking about one of eight equally sized sections. It denotes a ratio of 1/8. Reading options include: One-eighth, or

1 by 8

13 1/3 divided by 3 4/5

Let's first convert these mixed numbers to incorrect fractions.

13  1/3 =  13(3) + 1 = 39 + 1 = 40/3

3 4/5 = 3(5) + 4= 19/5

Now that we have divided 40/3 by 19/5, we can just switch the operation to multiplication and flip the second fraction because we know how to divide fractions.

40/3 x 5/19 = 200/57

he can bake 200/57 loaves or 3 29/57 loafs.

How do you format a standard form of writing?

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is fairly simple (x and y). When attempting to solve systems of two linear equations, this form is also very helpful.

Answer:

y = -4/5x +1

Step-by-step explanation:

Slope formula says that y=mx+b.

In terms of words, it means that y is equivalent to slope times x plus the y-intercept.

Slope= rise/run. You rise 4 and run 5. (which is 4/5) However, the slope is negative so be careful with that.

We know the y intercept is 1 so replace that for b.

Put it together and you get y=-4/5x+1

e.) Px + Qy = R

*Please explain how you got your answer because I really don't understand this!

Answers

Answer:

The systems that are guaranteed have the solution (3, -1) are;

a.) (P + F)·x + (Q + G)·y = R + H

F·x + G·y = H

d.) P·x + Q·y = R

(F - 2·P)·x + (G - 2·Q)·y = H - 2·R

e) P·x + Q·y = R

5·F·x + 5·G·y = 5·H

Step-by-step explanation:

The given system of equation are;

a) P·x + Q·y = R...(1)

F·x + G·y = H...(2)

The solution of the system of equation = (3, -1)

Adding equation (1) to equation (2) gives;

P·x + Q·y + F·x + G·y = R + H

(P + F)·x + (Q + G)·y = R + H...(3)

Therefore, given that equation (3) is obtained from equation (1) and (2) by addition, equation (3), (P + F)·x + (Q + G)·y = R + H, we have;

The system of  equation;

(P + F)·x + (Q + G)·y = R + H

F·x + G·y = H, derived from the given system of equation Is bound to have the same same solution (3, -1) as the given system of equation

d.) By multiplying equation (1) by 2, we have;

2 × (P·x + Q·y) = 2 × R

2·P·x + 2·Q·y = 2·R...(4)

Subtracting equation (4) from equation (2) gives;

F·x + G·y - (2·P·x + 2·Q·y) = H - 2·R

F·x - 2·P·x + G·y - 2·Q·y = H - 2·R

(F - 2·P)·x + (G - 2·Q)·y = H - 2·R

Therefore, for the following system, obtained from the original system, we have that the solution is (3, -1);

P·x + Q·y = R

(F - 2·P)·x + (G - 2·Q)·y = H - 2·R

e) For the system of equation, we have;

P·x + Q·y = R

5·F·x + 5·G·y = 5·H

The above system of equation is obtained from the original system by multiplying equation (2) by 5, therefore the solution of the system P·x + Q·y = R, 5·F·x + 5·G·y = 5·H is the same as the solution for the original system of equations (3, -1).

A right rectangular prism is sliced parallel to the base. What is the area of the resulting two-dimensional cross-section?

Answers

Answer:

The area of the resulting two-dimensional cross-section is 12 cm².

Step-by-step explanation:

The area of the cross-section of the right rectangular prism, parallel to the base, is given by the area of a rectangle:

[tex] A_{cs} = A_{r} = a*b [/tex]

Where:

[tex] A_{cs}[/tex]: is the area of the cross-section

[tex] A_{r} [/tex]: is the area of a rectangle

a: is the length of one side of the rectangle = 4 cm

b: is the length of the other side of the rectangle = 3 cm

Hence, the area of the cross-section is:

[tex] A_{cs} = a*b = 4 cm*3 cm = 12 cm^{2} [/tex]      

Therefore, the area of the resulting two-dimensional cross-section is 12 cm².

How to read linear equations?

Answers

To read a linear equation, first, identify the constants and the variable, then determine the coefficient of the variable.

A linear equation is an equation that contains two variables and can be written in the form of ax + b = 0, where 'a' and 'b' are constants and 'x' is the variable.  This coefficient will indicate how the variable is related to the constants. Then, solve the equation by isolating the variable to determine its value.

To read a linear equation, start by identifying the constants and the variable. The constant is the numerical value that is not connected to the variable. For example, in the equation "2x + 4 = 0", the constants are '2' and '4'. The variable is the letter that represents the values that can change. In this equation, the variable is 'x'.

Next, determine the coefficient of the variable. The coefficient is the numerical value in front of the variable. It represents how the variable is related to the constants. In this example, the coefficient of 'x' is '2'. This means that the value of 'x' will be twice as much as the constants.

Once the constants, variables, and coefficients have been identified, the equation can be solved.

Answers

Answer:

tan(θ) is undefined.

Step-by-step explanation:

Recall that tan(θ) = sin(θ) / cos(θ). We are given that sin(θ) = -1. Hence:

[tex]\displaystyle \tan\theta=\frac{\sin\theta}{\cos\theta}=-\frac{1}{\cos\theta}[/tex]

Since 1 / cos(θ) = sec(θ):

[tex]\tan\theta=-\sec\theta[/tex]

We can square both sides:

[tex]\tan^2\theta=\sec^2\theta[/tex]

From the Pythagorean Identity:

[tex]\tan^2\theta+1=\sec^2\theta[/tex]

Substitute:

[tex]\tan^2\theta+1=\tan^2\theta[/tex]

So:

[tex]1\neq0[/tex]

Since we acquire an untrue statement, no solutions exist.

If needed, refer to the unit circle. Recall that sin(θ) only equals -1 when θ = 3π/2 (on the interval [0, 2π)). At 3π/2, cos(θ) = 0. Since tan(θ) = sin(θ) / cos(θ), tan(θ) is undefined whenever sin(θ) = -1 (or 1).

Can 30 60 and 90 be the angles of a triangle?

Answers

No, the sum of the angles of a triangle must add up to 180 degrees. 30 + 60 + 90 = 180, so these angles cannot form a triangle.

The sum of the angles of a triangle must always add up to 180 degrees. To determine if a set of angles can form a triangle, add the angles together. If the sum is 180, the angles can form a triangle. In this case, 30 + 60 + 90 = 180, which does not equal 180. Therefore, these angles cannot form a triangle.

the length breadth and height of a cuboid are in the ratio 7:5:2 its volume is 35840cm³

Answers

The length of the cuboid is 56 cm.

The breadth of the cuboid is 40 cm.

The height of the cuboid is 16 cm.

What is a cuboid?

A cuboid is a three-dimensional shape where the volume is given by

Length x width x height.

We have,

Volume of a cuboid = 35840 cm³

The ratio of length, breadth, and height of the cuboid = 7:5:2

This means,

Length = 7x

Breadth = 5x

Height = 2x

Now,

(7x)(5x)(2x) = 35840

70x³ = 35840

x³ = 512

x = ∛512

x = 8

Now,

Length = 7x = 7 x 8 = 56 cm

Breadth = 5x = 5 x 8 = 40 cm

Height = 2x = 2 x 8 = 16 cm

Thus,

The length, breadth, and height of the cuboid are 56cm, 40cm, and 16 cm.
