The product of the areas of two rectangular rugs is 84. If each of the dimensions is a prime number, what are the four dimensions? PLEASE help FAST!!!!
A.) 2,3,3,7
b.) 3,3,4,7
C.)2,2,3,3
D.)2,2,3,7
Final answer:
The correct dimensions for the two rectangular rugs, given that the product of their areas is 84 and each dimension is a prime number, are 2, 3, 3, and 7. Option : A) 2, 3, 3, 7 is correct answer .
Explanation:
The student's question is about finding the four dimensions of two rectangular rugs given that the product of their areas is 84 and each dimension is a prime number. We can break down the number 84 into its prime factors which are 2, 2, 3, and 7. Because dimensions must be prime numbers and since the only way to multiply four factors to get 84 is to pair them as (2 x 3) and (2 x 7), the dimensions of the rectangles are 2, 3, 2, and 7. However, since we know that the dimensions of the rugs must also be lengths, and lengths cannot be repeated for the same rug, it follows that the correct option must list each length only once.
Therefore, the four dimensions cannot be 2, 3, 2, and 7 since this would imply one rug has dimensions 2 x 2 which would not yield a prime number length for one side. Looking at the options given, the only set of dimensions that fulfill the criteria of being prime numbers and not repeating any length for the same rug is 2, 3, 3, and 7. Thus, the correct answer is: A) 2, 3, 3, 7.
The four dimensions of the rectangular rugs are 2, 2, 3, and 7. Hence, the correct option is D.
The four dimensions of the rectangular rugs are 2, 2, 3, and 7.
To find the dimensions, we need to factorize 84, which is 2 x 2 x 3 x 7 = 2^2 x 3 x 7.
Therefore, the dimensions are 2, 2, 3, and 7, which are all prime numbers.

Answer:
y=x+5
Step-by-step explanation:
Looking at the answer choices, at first glance you see x=0 and y=5, this mean the y-intercept is 5. And in the equation y=mx+b, positive 5 will go into b.
The only answer with +5 as y-intercept is y=x+5
Now what if there are multiple +5 for y-intercept?
If there is multiple +5, you will also need to find the slope, you can find the slope by using

We divide the number line into ___ so we know how far to move left or right when doing equations.
Answer:
units
Step-by-step explanation:
I had this question on flocabulary.
We divide the number line into intervals to understand how far we need to move left or right when solving equations. This division into intervals creates a physical representation that helps visualize calculations and absolute differences between numbers.
Explanation:We divide the number line into intervals so we know how far to move left or right when doing equations. For understanding, let's consider an example. If we're working with whole numbers and the number line is divided into single-unit intervals, moving to the right from 0 to 5 means we've added 5 to our original number. Similarly, moving to the left of 0 to -5 means we've subtracted 5 from our original number.
The division of the number line helps to visualize the calculation process and see physical representation of absolute differences between numbers. For example, if we make the distance between each interval equal to one unit, the distance between 1 and 3 on the number line is 2 units, which corresponds to the absolute difference between these numbers.

Seth solved a quadratic equation. His work is shown below, with Step 3 missing.
What could Seth have written as the result from Step 3?
+ (x 1)2 + 5 = 23
5(x - 1)2 = 18
Step 1
(x - 1)2 = 36
Step 2
Step 3
x = -5 or = 7
Step 4
Answer:
|x - 1| = 6
Step-by-step explanation:
After step 2, we have that:
(x - 1)^2 = 36
and after step 4, we have the results:
x = -5 or x = 7
After step 2, what we can do in step 3 is: use square root in both sides of the equation:
|x - 1| = 6
This equation can be split in two:
x - 1 = 6 -> x = 7
x - 1 = -6 -> x = -5
So Seth could write this equation in step 3:
|x - 1| = 6
The value of x from the given expression are 5 and 7
Solving expression for the variableGiven the expression
5(x - 1)^2 = 18
Step 2 as shown is given as:
(x - 1)^2 = 36
Take the square root of both sides
√(x - 1)^2 = √36
x - 1 = 6
The solutions are x - 1 = 6 and x + 1 = 6
x = 6 + 1 = 7
x = 6 - 1
x = 5
Hence the value of x from the given expression are 5 and 7

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. Out of the two given options, 3/4 is closer to 1.
What is a number line?A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.
The value of 13/10 is equal to 1.3, while the value of 3/4 is 0.75. Therefore, the difference between the two numbers from 1 will be equal to,
[tex]D_1 = 1.3-1 = 0.3[/tex]
[tex]D_2 = 1-0.75 = 0.25[/tex]
Since the value of 0.3 is greater than 0.25, therefore, the gap between 13/10 and 1 will be more than 3/4 and 1.
Hence, out of the two given options, 3/4 is closer to 1.

-3x + 6 <21
Which statement best describes the process used to solve the equations?
Answer:
From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that the process is exactly the same for solving the equation and solving the inequalityStep-by-step explanation:
Given that the two equations -3x + 6 = 21 and -3x + 6 <21
To find the statement best describes the process used to solve the equations :From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that
-3x+6-6=21-6
-3x=15
[tex]x=-\frac{15}{3}[/tex]
∴ x=-5-3x + 6 <21
-3x+6-6<21-6
-3x<15
[tex]x< -\frac{15}{3}[/tex]
∴ x< -5 From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that the process is exactly the same for solving the equation and solving the inequality.The first equation is a statement of equality, while the second is an inequality. The process is solving equations and inequalities.
The process used to solve the equations involves identifying whether the given expressions are equations or inequalities and then applying appropriate techniques to find the solution.
For the equation [tex]\( -3x + 6 = 21 \)[/tex], the goal is to find the value of [tex]\( x \)[/tex] that makes the equation true. We start by isolating [tex]\( x \)[/tex] on one side of the equation. By subtracting 6 from both sides and then dividing by -3, we find [tex]\( x = -5 \)[/tex]. This is the solution to the equation.
On the other hand, for the inequality [tex]\( -3x + 6 < 21 \)[/tex], the goal is to find the values of [tex]\( x \)[/tex] that satisfy the inequality. We follow similar steps as with the equation but with one crucial difference: when dividing by a negative number, the direction of the inequality sign must be reversed. After isolating [tex]\( x \)[/tex], we find [tex]\( x > -5 \)[/tex]. This represents all values of [tex]\( x \)[/tex] that make the inequality true.
In summary, the process involves understanding whether we are dealing with equations or inequalities, isolating the variable, and solving for its value. For inequalities, attention must be paid to reversing the inequality sign when dividing by a negative number.

It is
from the bag.
The probability of selecting a yellow disk from a bag of colored disks is 1/5 or 20%
The probability of selecting a yellow disk is 5 out of 25 disks, which simplifies to 1/5 or 0.2 (20%).
If you reach into the bag without looking, you have a 20% likelihood of randomly selecting a yellow disk from the total number of disks.
a. The probability that a yellow disk will be selected is 5/25 or 1/5, b. Complete the sentence to describe the likelihood of randomly selecting a yellow disk: It is 1/5 that a yellow disk will be randomly selected from the bag.
The probability of selecting a yellow disk from the bag is 1/5, as there are 5 yellow disks out of a total of 25 disks. This means that for every 5 disks chosen randomly, one is expected to be yellow. The likelihood of randomly selecting a yellow disk is thus 1 out of 5, or 20%. This probability reflects the relative abundance of yellow disks in the bag compared to other colors. With each random selection, there's an equal chance of picking any individual disk, making understanding probabilities crucial for predicting outcomes in random selections.

original price of a CD is $17.50 discount is 50%
Answer:
$8.75
Step-by-step explanation:
To calculate this you could use two methods. The first method is to find out what 10% is and multiply it by 5. The second method is to calculate 50% using the formula.
Method 1:
To work this out you would simply divide 17.50 by 10, which is 1.75. This is because percentages are out of 100 and so by dividing by 10 we are finding out what 10% is. Then you would multiply 1.75 by 5, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.
1) Divide 17.50 by 10.
[tex]17.50/10=1.75[/tex]
2) Multiply 1.75 by 5.
[tex]1.75*5=8.75[/tex]
3) Minus 8.75 from 17.50.
[tex]17.50-8.75=8.75[/tex]
4) The new price is $8.75
Method 2:
The formula for percentages is.
[tex]\frac{percentage}{100} * amount[/tex]
To work this out you would first divide 50 by 100, which gives you 0.5. Then you would multiply 0.5 by 17.50, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.
1) Divide 50 by 100.
[tex]50/100=0.5[/tex]
2) Multiply 0.5 by 17.50.
[tex]17.50*0.5=8.75[/tex]
3) Minus 8.75 from 17.50.
[tex]17.50-8.75=8.75[/tex]
4) The new price is $8.75.

Four friends are racing. Lisa finishes four hours ahead of Tony, with Pete finishing eight hours ahead of Max. Max needed six more hours to finish than Lisa. What order do they cross the finish line in?
Need steps. Please
Answer:
Pete, Lisa, Tony, Max
Step-by-step explanation:
Lisa is 4 ahead Tony, putting Tony 4 behind Lisa
Pete is 8 ahead Max, putting Max 8 behind Pete
Lisa is also 6 ahead Max, putting Max 6 behind Lisa
So, Pete is 8 ahead Max, but lisa is 6 ahead Max, so Pete is ahead of Lisa by 2
Then lisa is 4 ahead Tony, so tony is 4 behind lisa and 6 behind Pete
Therefore (I know its confusing) The order is Pete, Lisa, Tony, Max
Final answer:
By analyzing the time differences between their finishes, we can determine that the friends cross the finish line in this order: Lisa first, Pete second, Tony third, and Max last.
Explanation:
To solve the question regarding the order in which four friends cross the finish line, we will use logical reasoning and simple arithmetic based on the information provided. Lisa finishes four hours ahead of Tony, Pete is eight hours ahead of Max, and Max finishes six hours after Lisa. From the given information, we can set up a sequence of events to determine the order in which they finish.
Let’s assume Lisa finishes first. Then Max finishes six hours after Lisa.Since Pete finishes eight hours ahead of Max, Pete must finish ahead of Max and two hours after Lisa, placing him in second.Lisa finishes four hours ahead of Tony, which would mean Tony finishes after Lisa but before Max.Therefore, the final order is: Lisa, Pete, Tony, and then Max.Gertrude is deciding which cell phone plan is the best deal for her to buy.

Proving the parallelogram diagonal theorem answers please
The parallelogram diagonal theorem pertains to vector addition and subtraction, where the diagonals of a parallelogram indicate the resultant and the difference of two vectors. The precision of the resultant vectors is attained through trigonometry laws or by drawing the vectors to scale, with the alternative method of components simplifying calculations. The Pythagorean theorem also aids in accurately determining the lengths of resultants in right-angled vector scenarios.
Explanation:Proving the Parallelogram Diagonal TheoremIn geometry, the parallelogram diagonal theorem states that when two vectors form the sides of a parallelogram, the diagonals of that parallelogram represent the sum and the difference of the two vectors. This can be understood by two distinct operations:
The magnitude and direction of these resultant vectors cannot simply be calculated as the arithmetic sum or difference of the magnitudes of individual vectors A and B. Instead, we must apply trigonometry laws or construct the vectors to scale and measure directly if precision is not paramount. The method of components, involving breaking down vectors into their orthogonal components along the axes, offers an alternative by circumventing complex algebraic calculations.
To add multiple vectors, we can sequentially apply the parallelogram rule to combine pairs until we derive the overall resultant. The process is both commutative and associative, meaning that the order of addition does not affect the final resultant vector.
The Pythagorean theorem, crucial for right triangles, allows us to calculate the straight-line distance (hypotenuse) when we know the lengths of the other two sides. It serves as another example of how vector components can simplify the calculation of resultants in orthogonal directions.
