why
[tex] \frac{1}{ \sqrt{3 } - 1} \times \frac{ \sqrt{3} + 1}{ \sqrt{3} + 1} = \frac{1 + \sqrt{3} }{2} [/tex]
why not 1+✓3 ?
Answer:
Hey there!
When multiplying fractions, we multiply the numerator by the numerator, and denominator by denominator.
1 x [tex]\sqrt{3}+1[/tex] = [tex]\sqrt{3}+1[/tex]
[tex]\sqrt{3} -1 (\sqrt{3} +1)[/tex] = 2
Thus, the answer is ([tex]\sqrt{3}+1[/tex])/2

How many places after the decimal point does the equivalent decimal have if: a. the denominator of the fraction is 10 b. the denominator of the fraction is 100? Look at your answers to problem 4. Explain the reasoning you used to find the answers.
Answer:I think A is the answer sorry if I’m wrong
Step-by-step explanation:
The equivalent decimal have 1 places right after the decimal point, if
the denominator of the fraction is 10.
And, The equivalent decimal have 2 places right after the decimal point, if
the denominator of the fraction is 100.
Here,
We have to determine places after the decimal point does the equivalent decimal have,
The denominator of the fraction is 10 and the denominator of the fraction is 100.
What is Decimal representation?
A decimal number is a number where the integer part is separated from the fractional part with the help of a decimal point.
Now,
Let the number 2 in numerator,
Denominator = 10
Then, Fraction = 2/10 = 0.2
Hence, The equivalent decimal have 1 places right after the decimal point.
Let the number 3 in numerator,
Denominator = 100
Then, Fraction = 3/100 = 0.03
Hence, The equivalent decimal have 2 places right after the decimal point.
So, The equivalent decimal have 1 places right after the decimal point, if
the denominator of the fraction is 10.
And, The equivalent decimal have 2 places right after the decimal point, if
the denominator of the fraction is 100.

What vector points from the origin to the point (3, -2, 3)?
PLEASE PLEASE HELP
Answer:
The vector [tex]\vec v = (3,-2,3)[/tex] points from the origin to the point (3,-2,-3).
Step-by-step explanation:
Geometrically speaking, a vector is the change between a final point and a initial point. Since vector are located in space, the origin is represented by point (0, 0, 0) That is:
[tex]\vec v = (3,-2,3)-(0,0,0)[/tex]
[tex]\vec v = (3-0,-2-0,3-0)[/tex]
[tex]\vec v = (3,-2,3)[/tex]
The vector [tex]\vec v = (3,-2,3)[/tex] points from the origin to the point (3,-2,-3).
To solve the problem we must know about Vector points.
PointA point is a position in space. It is represented by a dot.
VectorA vector is something that has both magnitude and direction but no fixed position in space. it is represented by an arrow pointing in a particular direction.
Vector pointsWhen we draw vectors, we attach them to specific points, but we should remember that the vector has no fixed position. These points are known as vector points.
The vector will point toward the point (3, -2, 3) in space.
Given to usvector points = (3, -2, 3)Origin, (0, 0, 0)SolutionAs we know a vector has no fixed position in space, but it points towards its final condition starting from the initial condition. Therefore, its tail is towards the initial condition while its arrowhead is towards the final condition. Thus,
Vector calculationFinal condition - Initial Condition
= (3, -2, 3) - (0, 0, 0)
= (3-0, -2-0, 3-0)
= (3, -2, 3)
Hence, the vector will point toward the point (3, -2, 3) in space.

Answer: Carpet required: 35 square yards. Cost: $700.
Wallpaper required 185 square feet, 4.2 double rolls needed, but you must buy full rolls. So 5 rolls will cost $125.
Step-by-step explanation:
Multiply the dimensions of the floor to get total square footage. Divide by 9 to convert to square yards.
314.5 ÷ 9 = 34.944. Round to 35 square yards. Multiply by $20 to get the cost of the carpet.
Multiply the dimensions of the wall to get total square footage.
Divide by 44 to get the number of rolls needed. Partial rolls not allowed. So it's 5 rolls times the $25 per "double roll." $125 is the cost.

company a operates stores under multiple banners in 34 states in the us a. how many states do not have a store operated by company a? b. what fraction of states do not have a store operated by company a?
Answers: 16 states and [tex]\frac{16}{50}[/tex]
Explanation:
Question A involves finding the number of states that do not have a store operated by company A. This can be easily found by subtracting the number of states where the company operates stores, which is 34 states, from the total of states, which is 50.
50 - 34 = 16
This means 16 states do not have a store operated by this company
Question B involves writing a fraction to represent the number of states that do not have a store operated by the company. A fraction includes a numerator (top number) that represents the parts selected (number of states without a store: 16), and a denominator, which is the total of parts (total of states: 50). Thus, the fraction is [tex]\frac{16}{50}[/tex]. Moreover, this can be simplified as [tex]\frac{8}{25}[/tex] by dividing both numbers by the seame number (2).
The expression, 20(4x) + 500, represents the cost in dollars of the materials and labor needed to build a square fence with side length x feet around a playground. What is the meaning of the coefficient 20?
Answer:
20 represent the cost per variable inputs
Step-by-step explanation:
C(x) = 20(4x) + 500
Total cost is the addition of variable cost and fixed cost
Fixed cost are cost that do not change during the production process such as machinery, furnitures and fittings.
Variable cost are cost of production that changes with production process such as cost of labor, cost of raw materials.
C(x) = 20(4x) + 500
C(x) represent the total cost
20(4x) represent the variable cost
500 represent the fixed cost
From the variable cost 20(4x)
20 represent the cost per variable inputs

Situation 1: Two students, Theo and Lance, each have some chocolates. They know that
they have the same number of chocolates. Theo has four full bags of chocolates and five
loose chocolates. Lance has two full bags of chocolates and twenty-nine loose
chocolates.
Determine the number of chocolates in a bag. Determine the number of chocolates each
child has.
They each have two chocolates so those numbers of chocolates are the same.
Not counting the tubs, Arthur has one bag of chocolates and 25 loose chocolates; Oliver has two bags and 7 loose. If they both have the same total number of chocolates, then the difference in the number of loose chocolates they have (25-7=18) must be the number of chocolates in a bag.
There is no information given, in the problem as you show it, that allows us to determine the number of chocolates in a tub.
Answers: chocolates in a bag: 18. chocolates in a tub: unknown.

How many combinations are possible on a 4 number computer cable lock. each space can be any number 0-9 . The only exception is that all four numbers cannot be the same. How many combinations are possible ?
Answer:
5040
Step-by-step explanation:
Given
Digits: 0 - 9
Required
Number of combinations of 4 digits where no repetition is allowed
First, we need to count the number of digits
[tex]Number = 10[/tex]
Then, we perform the following analysis.
The first space can contain any of the 10 digits;
The second space can contain any of the remaining 9 digits;
The third space can contain any of the remaining 8 digits;
The fourth space can contain any of the 7 digits;
Hence; the umber of combination is
[tex]Number = 10 * 9 * 8 * 7[/tex]
[tex]Number = 5040[/tex]
Hence, there are 5040 possible combinations

Find the values for k so that the intersection of x = 2k and 3x + 2y = 12 lies in the first quadrant. PLEASSSSEEEE
Answer:
0< k < 2
Step-by-step explanation:
x = 2k
3x + 2y = 12
Substitute the first equation into the second equation
3(2k) +2y = 12
6k+2y = 12
Subtract 6k from each side
2y = 12 -6k
Divide by 2
y = 6 - 3k
For this to be in the first quadrant y > 0
6 - 3k > 0
6 > 3k
Divide by 3
2 > k
The lower limit is when it reaches the axis or when k=0
0 <k <2
Checking for x
x = 2k
If 0<k <2 then it will be in the first quadrant
Answer:
k = any value between 0 and 2
Step-by-step explanation:
We can start by considering the graph of 3x + 2y = 12. If you convert this line into point - slope form it will have a negative slope, and hence will extend infinitely in the negative direction. Therefore if we calculate the x - intercept, k will be bound by 0 to the x - intercept if their intersection lies in the first quadrant.
3x + 2y = 12,
3x + 2(0) = 12,
3x = 12,
x = 4 - this is the x - intercept
As x = 4 is the x - intercept, k can be any value between 0 and 4, and will lie in the first quadrant. But remember that we have the equation " x = 2k. " k will only be between 0 and 4 is the equation is " x = k. "
- Therefore k will instead be any positive value between 0 and 2.
