Which expression is a perfect cube?

Answer:

A

Step-by-step explanation:

The correct equation to find 40 percent of 25 is: D. Start Fraction 40 divided by 4 Over 100 divided by 4 End Fraction = Start Fraction 10 Over 25 End Fraction

Let's go through each option and determine the correct equation step by step.

A. Start Fraction 25 divided by 1 Over 40 divided by 1 End Fraction = Start Fraction 25 Over 40 End Fraction

This equation represents the division of 25 by 40. However, we want to find 40 percent of 25, not divide 25 by 40. So, this equation is not the correct one.

B. Start Fraction 100 times 4 Over 40 times 4 End Fraction = Start Fraction 400 Over 16 End Fraction

In this equation, we multiply 100 by 4 and divide it by 40 multiplied by 4. Simplifying this expression, we get 400 divided by 16, which is equal to 25. This equation does not give us the value of 40 percent of 25, so it is not the correct one.

C. Start Fraction 40 times 4 Over 25 times 4 End Fraction = Start Fraction 160 Over 100 End Fraction

Here, we multiply 40 by 4 and divide it by 25 multiplied by 4. Simplifying this expression, we get 160 divided by 100, which is equal to 1.6. This equation does not give us the value of 40 percent of 25, so it is also not the correct one.

D. Start Fraction 40 divided by 4 Over 100 divided by 4 End Fraction = Start Fraction 10 Over 25 End Fraction

In this equation, we divide 40 by 4 and divide 100 by 4. Simplifying this expression, we get 10 divided by 25, which is equal to 0.4. This equation represents 40 percent of 25, as 0.4 is equal to 40 percent when expressed as a decimal. Therefore, the correct equation is D.

The solutions for x are x < 16 and x < 7/ 3 respectively

The absolute value of a real number can be defined as the non-negative value of that number without regard or consideration to its sign.

It is also described as the modulus of a number.

Given the inequality;

||x+4|-7|<5

Take the absolute value

x + 4 + 7 < 5

collect like terms

x < 5 + 4 + 7

Add like terms

x < 16

||3x-1|+5|<1

Take the absolute value

3x + 1 + 5 < 1

collect like terms

3x < 1 + 5 + 1

3x < 7

Make 'x' the subject

x < 7/ 3

Thus, the solutions for x are x < 16 and x < 7/ 3 respectively.

Answer:

Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75

Step-by-step explanation:

Let,

x be the cost of each apple pie

y be the cost of each lemon merigue pie

According to given statement;

5x+2y=80     Eqn 1

3x+6y=90     Eqn 2

Multiplying Eqn 1 by 3

3(5x+2y=80)

15x+6y=240    Eqn 3

Subtracting Eqn 2 from Eqn 3

(15x+6y)-(3x+6y)=240-90

15x+6y-3x-6y=150

12x=150

Dividing both sides by 12

[tex]\frac{12x}{12}=\frac{150}{12}\\x=12.50[/tex]

Putting x=12.50 in Eqn 1

5(12.50)+2y=80

62.50+2y=80

2y=80-62.50

2y=17.50

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{17.50}{2}\\y=8.75[/tex]

Hence,

Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75

Answer:

x =-18

Step-by-step explanation:

5(x + 9) = -45

Divide each side by 5

5/5(x + 9) = -45/5

x+9 = -9

Subtract 9 from each side

x+9-9 = -9 -9

x =-18

Answer:

The correct answer is x = -1.

Step-by-step explanation:

Step 1: 5(x + 9) = -45 <----- This is the original problem.

Step 2: 5(9x) = -45 <----- Add the variable.

Step 3: [tex]\frac{5(9x)}{5} = \frac{-45}{5}[/tex] <----- Divide both sides by 5.

Step 4: 9x = -9 <----- Simplify

Step 5: 9x/9 = -9/9 <----- Divide both sides by 9.

            x = -1

The sum of the scientific notation is 8.655 * 10^9

The standard form of a  scientific notation is expressed as A * 10^n

where

A is any value between 1 and 10

n is any integer

Given the expression below;

(8.42 x 10^9) + (2.35 x 10^8)

This can also be expressed as

(84.2 x 10^8) + (2.35 x 10^8)

(84.2+2.35) * 10^8

86.55 * 10^8

Step-by-step explanation:

the derivative of the sum of terms in x is the same as the sum of the derivatives of the individual terms.

d/dx × (-4sin(x) + 9x) = d/dx × (-4sin(x)) + d/dx × (9x)

and also : the derivative of a term in x multiplied by a constant c is c × derivative of the term in x.

d/dx × (-4sin(x)) + d/dx × (9x) =

-4 × (d/dx × sin(x)) + 9 × (d/dx × x)

so, what is the derivative of sin(x) ? cos(x)

what is the derivative of x ? 1

so, we have as result :

-4cos(x) + 9

Answer:

If you roll two dices, you can get as results all numbers from 2 to 12. Among these, the prime numbers are 2, 3, 5, 7, 11. The probability you get each of them is: 2: you can get it only as 1+1, so one combination over 36 possibility. Probability: 1/36. 3: you can get it as 1+2 or 2+1, so two combinations over 36 possibility. Probability: 2/36. 5: you can get it as 1+4, 2+3, 3+2, 4+1, so four combinations over 36 possibility. Probability: 4/36. 7: you can get as 1+6, 2+5, 3+4, 4+3, 5+2, 6+1, so six combinations over 36 possibility. Probability: 6/36. 11: you can get it as 5+6 or 6+5 so two combinations over 36 possibility. Probability: 2/36. The total probability of getting a prime number is the sum of the probabilities, which is 15/36. So m=15, n=36 and 10m+n=150+36=186.

Step-by-step explanation:

Answer:

Clayton could use the relationship (x,y) - (y,x) to find the points of the image.

C’ will remain in the same location as C because it is on the line of reflection.

The image and the pre-image will be congruent triangles.

The image and pre-image will not have the same orientation because reflections flip figures

Step-by-step explanation:

Clayton needs to reflect the triangle below across the line y=x

Which statements about the reflection are true? Check all that apply.

Clayton could use the relationship (x,y) - (y,x) to find the points of the image.Clayton could negate both the x and y values in the points to find the points of the image.C’ will remain in the same location as C because it is on the line of reflection.C’ will move because all points move in a reflection.The image and the pre-image will be congruent triangles.The image and pre-image will not have the same orientation because reflections flip figures.

Solution:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.

Reflection is the flipping of a figure over a line. If a point A(x, y) is reflected over the line y=x, the new location is A'(y, x).

If the triangle ABC with vertices A(5.5, 7), B(6, 2), C(4, 4) is reflected over the line y=x, the new location would be A'(7, 5.5), B'(2, 6) and C'(4, 4).

A. Clayton could use the relationship (x,y) - (y,x) to find the points of the image. Reflection across the line y = x is the swapping of the x and y coordinates. Option A is correct

B. Clayton could negate both the x and y values in the points to find the points of the image. Option B is wrong

C. C’ will remain in the same location as C because it is on the line of reflection. C is on the line of reflection, hence it remains the same. Option C is correct.

D. C’ will move because all points move in a reflection.

Option D is wrong.

E. The image and the pre-image will be congruent triangles.

Option E is correct. Reflection preserves the shape and length of an object.

F. The image and pre-image will not have the same orientation because reflections flip figures. Option F is correct

Step-by-step explanation:

Answer:

The value of b is 5 times the value of a.

Step-by-step explanation:

The rule that describes the pattern in the table is that the value of b is 5 times the value of a.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The table shows two sets of values, a and b, where b is obtained by multiplying a by 5.

For example, when a = 1, b = 5, and when a = 2, b = 10.

This pattern continues throughout the table.

Therefore,

The rule that describes the pattern in the table is that the value of b is 5 times the value of a.
