Option D:

[tex]\left(y^{2}+3 y+7\right)\left(8 y^{2}+y+1\right)=8 y^{4}+25 y^{3}+60 y^{2}+10y+7[/tex]

Solution:

Given expression is [tex]\left(y^{2}+3 y+7\right)\left(8 y^{2}+y+1\right)[/tex].

To find the product of the expression:

[tex]\left(y^{2}+3 y+7\right)\left(8 y^{2}+y+1\right)[/tex]

Multiply each term of the first term with each term of the 2nd term.

           [tex]=y^{2}\left(8 y^{2}+y+1\right) +3 y\left(8 y^{2}+y+1\right) +7\left(8 y^{2}+y+1\right)[/tex]

Using the exponent rule: [tex]a^m \cdot a^n = a^{m+n}[/tex]

           [tex]=\left(8 y^{4}+y^3+y^2\right) +\left(24 y^{3}+3y^2+3y\right) +\left(56 y^{2}+7y+7\right)[/tex]

           [tex]=8 y^{4}+y^3+y^2+24 y^{3}+3y^2+3y+56 y^{2}+7y+7[/tex]

Arrange the terms with same power.

           [tex]=8 y^{4}+y^3+24 y^{3}+y^2+3y^2+56 y^{2}+7y+3y+7[/tex]

           [tex]=8 y^{4}+25 y^{3}+60 y^{2}+10y+7[/tex]

Missing fraction
blank + 1/16 = 3/2

Answers

Final answer:

To solve for the missing fraction in the equation blank + 1/16 = 3/2, convert 3/2 to a fraction with a denominator of 16 to give 24/16. Then, subtract 1/16 from 24/16 to get the missing fraction, which is 23/16.

Explanation:

To find the missing fraction in the equation blank + 1/16 = 3/2, we first need to express 3/2 with the same denominator as 1/16 to facilitate addition. The common denominator for 16 and 2 is 16, so we can rewrite 3/2 as 24/16 (since 3 × 8 = 24 and 2 × 8 = 16). Our equation now is blank + 1/16 = 24/16. To solve for the missing fraction (blank), we subtract 1/16 from 24/16, which gives us 23/16.

Example:

Rewrite 3/2 as 24/16

Subtract 1/16 from 24/16 to find the missing number

The missing fraction is 23/16

This method demonstrates how to find a missing fraction by creating a common denominator and then subtracting to isolate the missing number.

Answers

Question:

A rectangular prism has a length of 4 1/2 millimeters, a width of 4 1/2 millimeters, and a height of 6 millimeters.

Sally has a storage container for the prism that has a volume of 143 cubic millimeters.

What is the difference between the volume of the prism and the volume of the storage container?

Answer:

The difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter

Solution:

Volume of rectangular prism is given as:

[tex]volume = length \times width \times height[/tex]

From given,

[tex]length = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\width = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\height = 6\ mm[/tex]

Therefore,

[tex]volume = \frac{9}{2} \times \frac{9}{2} \times 6 = 121.5\ mm^3[/tex]

Sally has a storage container for the prism that has a volume of 143 cubic millimeters

What is the difference between the volume of the prism and the volume of the storage container

Difference = 143 - 121.5 = 21.5

Thus difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter

Out of the 1236 employees who work for a particular company, 748 of them work in an office. One employee is selected every month to receive a free
lunch. The probability that the selected employee does not work in an office is

Answers

Answer:

458

Step-by-step explanation:

Final answer:

The probability that the selected employee does not work in an office is calculated by dividing the number of employees not working in an office (488) by the total number of employees (1236), resulting in a probability of approximately 0.395.

Explanation:

The question asks for the probability that the selected employee does not work in an office from a total of 1236 employees, where 748 work in an office. To find this, we first need to determine the number of employees who do not work in an office.

Employees not working in an office = Total employees - Employees working in an office

= 1236 - 748 = 488

Now, the probability of selecting an employee who does not work in an office is calculated by dividing the number of employees not working in an office by the total number of employees:

Probability = Number of employees not working in an office / Total number of employees

Probability = 488 / 1236

Therefore, the probability that the selected employee does not work in an office is approximately 0.395.

The sum of two numbers is 47 and the difference is 19. What are the numbers?

Answers

Answer: The two numbers are 33 and 14

Step-by-step explanation: We shall start by first assigning letters to unknown variables. Therefore let the two numbers be called a and b. The first clue in this question states that the sum of both a and b equals 47. That means we can write the expression;

a + b = 47.

The second clue states that their difference equals 19. This also can be expressed as follows;

a - b = 19

Now we have a pair of simultaneous equations which are

a + b = 47 ———(1)

a - b = 19 ———-(2)

We shall use the substitution method. Therefore from equation (1), make a the subject of the equation.

a = 47 - b

Next we substitute for the value of a in equation (2)

a - b = 19

47 - b - b = 19

47 -2b = 19

By collecting like terms we now have 47 - 19 = 2b

28 = 2b

Divide both sides of the equation by 2

14 = b

We can now substitute for the value of b into equation (1)

a + b = 47

a + 14 = 47

Subtract 14 from both sides of the equation

a = 33.

Therefore the two numbers are 33 and 14.

Final answer:

The two numbers with a sum of 47 and a difference of 19 are 33 and 14. We found this by setting up two equations based on the given information and solving for the two variables.

Explanation:

The sum of two numbers is 47 and the difference is 19. To find these two numbers, we can set up a system of equations and solve them. Let the numbers be x and y.

x + y = 47 (equation 1)x - y = 19 (equation 2)

Adding both equations, we get 2x = 66, hence x = 33.

Substituting x in equation 1, we get 33 + y = 47, hence y = 47 - 33 = 14.

Therefore, the two numbers are 33 and 14.


A lizard is jumping across the water in search of food. The equation h = -12t2 + 6t
models the lizard's height in feet above the water t seconds after he jumps. How long
after Jumping is he back on the water?

Answers

Final answer:

To find the time when the lizard is back on the water, set the height equation equal to zero and solve for t. The lizard is back on the water 1/2 second after jumping.

Explanation:

To find the time when the lizard is back on the water, we need to set the height, h, equal to zero, and solve for t in the given equation, h = -12t^2 + 6t.

Substitute 0 for h:

0 = -12t^2 + 6t

Now we can solve for t. Rearrange the equation to quadratic form:

12t^2 - 6t = 0

Factor out a common factor of 6t:

6t(2t - 1) = 0

Set each factor equal to zero:

t = 0 or 2t - 1 = 0

If t = 0, it means the lizard is on the water at the time it jumps. Therefore, t = 0 is not the solution we're looking for. If 2t - 1 = 0, solving for t:

2t = 1

t = 1/2

Therefore, the lizard is back on the water 1/2 second after jumping.

Eric needs to order programs for the next school football game. Only 1 out of 2 people will buy a program for the game. If there will be 900 people at the game and programs come in boxes of 50, how many boxes of programs should Eric order?

Answers

Answer:

Eric should order 9 boxes of programs.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Probability of buying a program for the game = 1/2

Number of people at the game = 900

Number of programs per box = 50

2. How many boxes of programs should Eric order?

Let's calculate the answer this way:

Number of programs required for the next football game = Probability of buying a program for the game * Number of people at the game

Replacing with the values given, we have:

Number of programs required for the next football game = 1/2 * 900

Number of programs required for the next football game = 450

Now, we can calculate he number of boxes, this way:

Number of boxes of programs Eric should order = Number of programs required for the next football game /Number of programs per box

Replacing with the values given, we have:

Number of boxes of programs Eric should order = 450/50

Number of boxes of programs Eric should order = 9

How much more blue paint does she need to add to the mixture so that the ratio of white paint to blue paint becomes 1:7?

Answers

Given:

Ratio of white and blue paint is 2:3

Total quantity of paint is 20 litres

To find:

Quantity of blue paint to be mixed so that the ratio of white paint to blue paint becomes 1:7

Solution:

The ratio 2:3 totals 20 that is [tex]2x+3x=20\rightarrow5x=20\rightarrow x=4[/tex]

So, the quantity of white paint in the mixture is [tex]2\times4=8[/tex] and the quantity of blue paint in the mixture is [tex]3\times4=12[/tex]

Now, to get the final ratio as 1:7, Mary should have [tex]7\times8=56 \text{ litres }[/tex] of blue paint. So, she need to add [tex]56-12=44 \text{ litres}[/tex].

Therefore, Mary has to add 44 litres of blue paint to the mixture to make the ratio as 1:7.

The line 2y - x + 5 = 0 and the curve (10 – x)^2+ (y – 5)^ 2= 10 intersect at points A and B.
Find the coordinates of A and of B.​

Answers

Answer:

A(9, 2 ), B(13, 4 )

Step-by-step explanation:

Given the 2 equations

2y - x + 5 = 0 → (1)

(10 - x)² + (y - 5)² = 10 → (2)

Rearrange (1) expressing x in terms of y by adding x to both sides

x = 2y + 5 → (3)

Substitute x = 2y + 5 into (2)

(10 - (2y + 5))² + (y - 5)² = 10, that is

(10 - 2y - 5)² + (y - 5)² = 10

(5 - 2y)² + (y - 5)² = 10 ← expand the factors using FOIL

25 - 20y + 4y² + y² - 10y + 25 = 10

5y² - 30y + 50 = 10 ( subtract 10 from both sides )

5y² - 30y + 40 = 0 ( divide through by 5 )

y² - 6y + 8 = 0 ← in standard form

(y - 2)(y - 4) = 0 ← in factored form

Equate each factor to zero and solve for y

y - 2 = 0 ⇒ y = 2

y - 4 = 0 ⇒ y = 4

Substitute these values into (3) for corresponding values of x

y = 2 : x = 2(2) + 5 = 4 + 5 = 9 ⇒ (9, 2 )

y = 4 : x = 2(4) + 5 = 8 + 5 = 13 ⇒ (13, 4 )

Since we are not given the position of A or B in relation to each other then either of the points can represent A or B, that is

A(9, 2), B(13, 4)

OR

A(13, 4), B(9, 2)

You move down 3 units and right 6 units. You end at (4, -5). Where did you start?

Answers

Answer:

(-2, -2)

Step-by-step explanation:

In this problem, you only know the coordinates of the final point and the distance moved in order to get there (which was moving 3 units down and 6 units to the right). If you want to find the starting point, you simply have to go backwards by subtracting 3 from -5 because the y coordinates move upwards/downwards, and then subtracting 6 from 4 because the x coordinates go left/right in order to get your final answer, (-2, -2).

The sequence of movements can be reversed to find the initial position, which is (-2, -2).

To determine the starting point, we can reverse the given movements: moving down 3 units and right 6 units from the final position (4, -5). If we move 3 units up from the final y-coordinate (-5), we get -5 + 3 = -2.

Similarly, if we move 6 units left from the final x-coordinate (4), we get 4 - 6 = -2. Therefore, the starting point is (-2, -2).

To visualize this, imagine a coordinate plane where moving down represents decreasing the y-coordinate and moving right represents increasing the x-coordinate.

Starting at (-2, -2), moving down 3 units brings us to (-2, -5), and then moving right 6 units from there leads us to the final position (4, -5).
