The number of shirts an associate at a local department store can fold and restock, r, varies directly with the amount of time the associate spends folding and restocking, t. If Rebecca spends 2 h folding and restocking, she can fold and restock 129 shirts.


Which direct linear variation equation models the information?



A. r = 64.8t


B. r = 127t


C. r = 64.5t


D. r = 131t

Answers

The equation for the direct linear variation that models the given information is: C. r = 64.5t.

How to Write the Equation of a Direct Linear Variation?

The equation of a direct linear variation can be modelled as y = kx, where the variables are x and y, while the value of k is the constant of proportionality between the variables, x and y.

Given that:

r = number of shirts that can be fold and restock t = amount of time spent folding and restocking

We are told that r varies directly with t. Where k is the constant of proportionality, the equation of the direct linear variation between r and t can be expressed as r = kt.

Constant of proportionality, k = r/t

Number of shirts Rebecca can fold and restock (r) = 129

Amount of time she would spend (t) = 2

Find the constant of proportionality, k:

k = r/t = 129/2

k = 64.5

To write the equation for the direct linear variation, substitute k = 64.5 into r = kt:

r = 64.5t

Suppose the area of a rectangle is 9x3 + 27x2 + 36x + 18 and the length is 3x + 3. What is the width of the rectangle?• Width:

Answers

We know that the area of a rectangle is the width multiplied by its length, basically

[tex]A=b\cdot h[/tex]

But here, we have the area, which is a polynomial, same for the length, then, to find out the width we must do a division of polynomial, I'll call the unknown polynomial as P, we have

[tex]\begin{gathered} A=P\cdot l \\ \\ P=\frac{A}{l} \\ \\ P=\frac{9x^3+27x^2+36x+18}{3x+3} \end{gathered}[/tex]

So now we got to solve

[tex]P=\frac{9x^3+27x^2+36x+18}{3x+3}[/tex]

There is a lot of ways to solve it, first, I'll factor 3 in the denominator

[tex]P=\frac{9x^3+27x^2+36x+18}{3(x+1)}[/tex]

As well the numerator

[tex]P=\frac{3(3x^3+9x^2+12x+6)}{3(x+1)}[/tex]

Then we can already simplify 3, and get an easier expression

[tex]P=\frac{3x^3+9x^2+12x+6}{x+1}[/tex]

Now I'll factor using the grouping method, I want the numerator to be something like (x+1)*(another polynomial), doing that we can "cut" the (x+1).

One way to do it is to expand it in some simple sums, look at 3x³, we want a 3x² to match with him, but look that 9x² is 3x²+6x², let's write that way

[tex]P=\frac{3x^3+3x^2+6x^2+12x+6}{x+1}[/tex]

It doesn't seem to help us at all, but look that now we can factor 3x², then

[tex]P=\frac{3x^2(x+1)+6x^2+12x+6}{x+1}[/tex]

Look, we have our first (x+1) in the numerator. Let's use the same idea but now for the term 6x², we want a 6x to match with him, we have 12x, so let's write it as 6x + 6x.

[tex]P=\frac{3x^2(x+1)+6x^2+6x+6x+6}{x+1}[/tex]

Similar to what we did before, factor 6x, and again

[tex]P=\frac{3x^2(x+1)+6x(x+1)+6x+6}{x+1}[/tex]

Now we have one more (x+1).

Now the easiest one, factor 6

[tex]P=\frac{3x^2(x+1)+6x(x+1)+6(x+1)}{x+1}[/tex]

As we can see we have (x+1) multiplied by something in all terms in the numerator, then we can factor (x+1) now

[tex]P=\frac{(x+1)(3x^2+6x+6)}{x+1}[/tex]

Now we can cancel (x+1), and our final expression will be

[tex]P=3x^2+6x+6[/tex]

Therefore, the width is

[tex]3x^2+6x+6=\text{ width}[/tex]

E)A t-shirt is $23 and a pair of shorts is $7.50

Answers

First option is correct. A t - shirt cost $7.50 and a pair of shorts cost $23

Simultaneous linear equation: what is it?

First, it's crucial to understand linear equations.

Equation connects the two algebraic expressions with an equal to sign to demonstrate the equality between them.

Linear equations are those with one degree.

Simultaneous linear equations are two or more linear equations that can be solved simultaneously to find a common solution.

Let the price of one t-shirt be $x and price of one pair of shorts be $y

A t-shirt and two pairs of shorts cost $53.50

So, x + 2y = 53.50 .................... (1)

Two t-shirts and three pairs of shorts cost $84.

So, 2x + 3y = 84 ................ (2)

Multiplying (1) by 2,

2x + 4y = 107 .............(3)

Subtracting (2) from (3),

4y - 3y = 107 - 84

y = 23

Putting the value of y in (1)

x + 2[tex]\times[/tex]23 = 53.50

x = 53.50 - 46

x = 7.50

Tessa bought stock in a restaurant for $177.00. Her stock is now worth $263.73. What is the percentage increase of the value of Tessa's stock?

Answers

The percentage increase of the value of Tessa's stock is 49%.

Stock is a term used to describe the shares of ownership of a company. It is sometimes also called equity.

To find the percentage value change, we use the formula given below

P = (N-O)/O*100

Here, P = percentage change, N = new value, O = old value.

P = (263.73-177)/177*100

P = 86.73/177*100

P =  8673/177

P = 49%

Therefore, we can conclude that the total percentage increase of the value of Tessa's stock is 49%.

Answers

The probability of rolling a total of 7 on the two dice is 8/63

Probability:

In Mathematics, Probability is a branch that deals with the occurrence of possible outcomes in a random event or experiment. It is also defined as the ratio of the number of favorable outcomes and the total number of outcomes.

The probability of an event is denoted by P(E). And the probability of all the events in the sample space will equal to 1.  

Probability P(E) = No of favorable outcomes /Total No of outcomes  

Here we have,

The probabilities of rolling 1, 2, 3, 4, 5, and 6, on each die, are in the ratio 1: 2: 3: 4: 5: 6  

Let x, 2x, 3x, 4x, 5x, and 6x are the probabilities of rolling 1, 2, 3, 4, 5, and 6, on each die [ since they are in ratio 1: 2: 3: 4: 5: 6 ]  

As we know the total events in a probability = 1

=> x + 2x + 3x + 4x + 5x + 6x = 1  

=> 21 x = 1

=> x = 1/21  

From the above calculations,

The probabilities of rolling 1, 2, 3, 4, 5, and 6 are  [tex]\frac{1}{21} , \frac{2}{21}, \frac{3}{21}, \frac{4}{21}, \frac{5}{21}, \frac{6}{21}[/tex] respectively.  

The possible combinations of two dies that can give a total of 7 are

(1, 6) (2, 5) (3, 4) (4, 3) (5, 2) (6, 1)

Therefore, the probability of rolling a total of 7 on the two dice

=  the sum of the probabilities of rolling each combination

=  [tex]\frac{1}{21} . \frac{6}{21} + \frac{2}{21} .\frac{5}{21} + \frac{3}{21} . \frac{4}{21} + \frac{4}{21} . \frac{3}{21} + \frac{5}{21} .\frac{2}{21} + \frac{6}{21} .\frac{1}{21}[/tex]  

=  [tex]\frac{6}{441} + \frac{10}{441} + \frac{12}{441} + \frac{12}{441} + \frac{10}{441} + \frac{6}{441}[/tex]

Write an equation of the line that passes through the given point and is parallel to the graph of the given equation (-8,6);x+4y=20

Answers

The equation of the line that passes through the point (-8,6) is x + 4y = 16.

What is a slope?

A line's slope often indicates the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them. The letter "m" is frequently used to denote slope.

Given:

point = (-8,6)

equation : x+4y=20

x+4y=20

=> 4y = -x + 20

=> y = - x/4 + 5

Here the slope  m is -1/4.

Now  as the lines are parallel therefore the slope will be equal.

Therefore from the slope intercept form,

y - y1 = m (x - x1)

=> y - 6 = -1/4 ( x + 8 )

=> y - 6 = -x/4 - 2

=> x/4 + y = 4

=> x + 4y = 16

Answers

Price of a single product - part BHow much did Blair paid?

First step

We want to find the cost of each shirt Blair paid. In order to find it we want to find the total price Blair paid for the whole order and then divide it by 150 (total number of shirts).

She chose Company B.

They charge $3.10 per shirt, plus 4% of the total order for shipping.

There are 150 shirts, then the total order for shipping is:

150 · $3.10 = $465

we want to add the 4%. The 4% of $465 is

$465 · 4/100 = $465 · 0.04

= $18.60

If we add it to the total order for shipping:

$465 + $18.60 = $483.60

Second step

Now we divide the total price of 150 into 150: this is the cost for one shirt.

$483.60/150 = $3.224

If we round it to the nearest hundredth:

$3.224 ≅ $3.22

Answer- The total cost Blair paid for one T-shirt is $3.22

Mark up

We know that she needs to add 75% to the total cost.

Let's remember that every percentage is equivalent to it divided by 100: for example 100% is equivalent to 1. For 75%:

75% = 75/100 = 0.75

Then 75% is equivalent to 0.75.

This means that if we want to find the 75% of something we multiply it by its equivalent: 0.75.

Answer- She can calculate the markup by multiplying her total cost by 0.75

Sell price

Based on the previous parts, we know that we want to add the 75% (0.75) of the cost of each T-shirt Blair paid ($3.22).

We first find the 75% of $3.22 and then add it to it: it will be the cost of sell.

First step

The 75% of the total cost of each shirt ($3.22) is:

0.75 · $3.224 = $2.418

Second step

Adding the 75% to the total price:

$3.224 + $2.418 = $5.642

If we round it to the nearest hundredth:

$5.642 ≅ $5.64

Answer- Blair will sell each T-shirt at the carnival for $5.64.

Triangle congruence: Two triangles are said to be congruent if all three of their corresponding sides and angles have the same measure. Slides, rotations, flips, and turns can be used to make these triangles appear identical. They would be in alignment if they were moved. Congruence is represented by the letter "."

When two figures are similar to one another in terms of their size and shape, this is what mathematicians mean by congruence. It can be demonstrated that two triangles are congruent using four congruence rules in general.

However, all six dimensions must be discovered. In light of this, it is possible to determine the congruence of triangles using just three of the six values. Triangles that are congruent have equal corresponding sides and angles.

YX = 2 × AX (A = midpoint of YX)

ZX = 2 × CX (C = midpoint of ZX)

∠X and ∠X are congruent as the Reflexive property rule.

Therefore, triangle XAC is congruent to triangle XYZ (SAS similarity theorem)

First, we need to find the slope of the equation of the line that passes through the points (-2, 6) and (1, -3).

Remember that if a line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

To find the value of b w euse the fact that this line should pass through the point (2, 4), so:

4 = -3*2 + b

4 = -6 + b

4 + 6 = b = 10

The linear equation is:

y = -3*x + 10

To find two points we can evaluate in x = 1 and x = 0, we will get:

y = -3*1 + 10 = 7

y = -3*0 + 10 = 10

So we have the pair of points (1, 7) and (0, 10).

b) A perpendicular equation will have a slope equal to the inverse of the opposite, so we will have a line like:

y = (1/3)*x + c

To find the value of c we use the fact that this line passes through (3, 3), them:

3 = (1/3)*3 + c

3 = 1 + c

3 - 1 = c

2 = c

This line is:

y = (1/3)*x + 2

Again we evaluate in 0 and 1 to get the two points:

y = (1/3)*1 + 2 = 1/3 + 6/3 = 7/3

y = (1/3)*0 + 2 = 2

So we have the pair of points (1, 7/3) and (0, 2)

The weight, in pounds, of a certain type of adult squirrel is normally distributed with a mean of 4. 1 pounds and a standard deviation of 0. 5 pounds. What is the probability that a randomly selected squirrel has a weight less than 3 pounds? round your answer to four decimal places.

Answers

The percentage of squirrels that have a weight between 3 and 5 pounds is; 95.017%

What is percentage?In mathematics ,a percentage is a number that can be expressed as a fraction of 100. If you need to calculate the percentage of a number, divide the number by the whole number and multiply by 100. Percentages therefore mean 1 in 100.  If you need to convert a decimal number like 0.57 to percent just multiply  by 100 So 0.57 x 100 = 57. So as a percentage, 0.57 equals 57%. Percentage can be calculated by dividing the value by the total  and  multiplying the result by 100. The formula used to calculate the percentage is (value/total) x 100%.
