PLEASE HELPPP!!! QUESTION AND ANSWERS IN PICTUR

Answer: she can only make 6 completed barrettes

Step-by-step explanation:

Samantha makes hair barrettes from ribbon. The total length of ribbon that she has is 3 1/4 feet. Converting 3 1/4 feet to improper fraction, it becomes 13/4 feet.

She uses 1/2 feet of ribbon to make each barrette. This means that the number of completed barrettes that Samantha can make with the ribbon she has would be

(13/4)/(1/2) = 13/4 × 2/1

= 6 1/2 barrettes

The complete barrette must be whole number.

Therefore, she can only make 6 completed barrettes

Answer:

Maximum number of 3x3x2 bricks = 23.

Step-by-step explanation:

The volume of the box = 13 x 8 x 4 = 416 cubic unit

The volume of the brick with the dimensions = 18 cubic unit

Now as per the question, we want to fill an empty box with 416 cubic unit with the help of bricks which are 18 cubic unit each.

The maximum number of bricks required to fill the box = Volume of the box ÷ Volume of one brick.

→ The number of bricks required to fill the box = 416 ÷ 18 = 23.11

But, number of bricks can never be in fraction so it means a maximum of 23 bricks can accommodate in the given box. We will not choose 24 or more than 24 bricks because these much bricks will go out of the dimensions.

Note: Volume of a cuboid = length x breadth x height (l x b x h).

To solve the problem, you divide each dimension of the box by the corresponding dimension of the brick, rounding down to the nearest whole number to get the number of bricks that can fit in each direction. You then multiply these together to get the total. In this case, a maximum of 16 bricks can fit.

The problem at hand requires spatial reasoning and division. The challenge is to determine how many 'bricks' (which we'll engage as 3x3x2 units) can fit into a larger 'box' (which is 13x8x4 units). This can be determined by individually dividing the dimensions of the box by the dimensions of the brick.

For instance, considering the length, we divide 13 by 3 to get approximately 4.33. Considering that we can't fractionate a brick, we can place only 4 bricks along the length. Using the same approach, we divide 8 by 3 for the width to get approximately 2.67, and we can place 2 bricks here. It's the same for the height; 4 divided by 2 is 2. Therefore, we can place 2 bricks along the height.

To get the total number of bricks that can fit in the box, multiply the numbers together: 4 (length) x 2 (width) x 2 (height), giving a result of 16 bricks. Hence, a maximum of 16 bricks of size 3x3x2 can fit into a box of size 13x8x4 without going out of the box or overlapping.

Answer:

t = 460.52 min

Step-by-step explanation:

Here is the complete question

Consider a tank used in certain hydrodynamic experiments. After one experiment the tank contains 200 liters of a dye solution with a concentration of 1 g/liter. To prepare for the next experiment, the tank is to be rinsed with fresh water flowing in at a rate of 2 liters/min, the well-stirred solution flowing out at the same rate.Find the time that will elapse before the concentration of dye in the tank reaches 1% of its original value.

Solution

Let Q(t) represent the amount of dye at any time t. Q' represent the net rate of change of amount of dye in the tank. Q' = inflow - outflow.

inflow = 0 (since the incoming water contains no dye)

outflow = concentration × rate of water inflow

Concentration = Quantity/volume = Q/200

outflow = concentration × rate of water inflow = Q/200 g/liter × 2 liters/min = Q/100 g/min.

So, Q' = inflow - outflow = 0 - Q/100

Q' = -Q/100 This is our differential equation. We solve it as follows

Q'/Q = -1/100

∫Q'/Q = ∫-1/100

㏑Q  = -t/100 + c

[tex]Q(t) = e^{(-t/100 + c)} = e^{(-t/100)}e^{c} = Ae^{(-t/100)}\\Q(t) = Ae^{(-t/100)}[/tex]

when t = 0, Q = 200 L × 1 g/L = 200 g

[tex]Q(0) = 200 = Ae^{(-0/100)} = Ae^{(0)} = A\\A = 200.\\So, Q(t) = 200e^{(-t/100)}[/tex]

We are to find t when Q = 1% of its original value. 1% of 200 g = 0.01 × 200 = 2

[tex]2 = 200e^{(-t/100)}\\\frac{2}{200} = e^{(-t/100)}[/tex]

㏑0.01 = -t/100

t = -100㏑0.01

t = 460.52 min

Answer:

(x+3)

Step-by-step explanation:

Volume = Base area × height

Base area = x²+5x+6

= x²+2x+3x+6

= x(x+2)+3(x+2)

= (x+2)(x+3)

Since the length is the longer side, length = (x+3)

Dimensions of the box are:

(x+2)×(x+3)×(x+4)

Answer: The salesperson would take home $1088.01 for the day

Step-by-step explanation:

Let x represent the salesperson's total sales per day.

A salesperson earns $99 per day, plus a 9% sales commission. This means that in a day in which the salesperson makes a total sales of x dollars, the total amount that he would earn is

99 + 0.09x

Therefore, the function that expresses her earnings as a function of sales is

99 + 0.09x

if the total sales were $999, then the amount that the salesperson would take home for the day is

99 + 0.99 × 999

= $1088.01

ARITHMETIC SENTENCE

Step-by-step explanation:

Final answer:

Naledi's altitude sequence is an arithmetic sequence because it increases by a constant amount each hour.

Explanation:

Naledi's altitude at the beginning of the nth hour of her climb can be described by the function g(n), where g(n) is the altitude at that hour. Since she starts at 40 meters above sea level and increases her altitude by 10 meters every hour, the sequence representing her altitude over time is an arithmetic sequence. This is because each term in the sequence increases by a constant value, which is the definition of an arithmetic sequence.

The general formula for the nth term of an arithmetic sequence is aₙ = a₁ + (n - 1)d, where a₁ is the first term and d is the common difference between terms. In Naledi's case, a₁ is 40 meters (her initial altitude), and d is 10 meters (the constant increase each hour).

The domain for n is  [tex]-\infty<n<\infty[/tex]

Explanation:

The arithmetic sequence is    

To determine the domain of the sequence, let us consider  [tex]a_n[/tex] as  [tex]f(n)[/tex]  

Thus, the sequence becomes,  [tex]f(n)=4-4(n-1)[/tex]  

The domain of the function is the set of all x-values for which the function is real and well defined.

Since, the function has no domain constraints or undefined points. Therefore, the domain of the function is

Thus, the domain of the arithmetic sequence  [tex]a_n=4-4(n-1)[/tex] is  [tex]-\infty<n<\infty[/tex]

Answer:

The work done is 5.084 J

Step-by-step explanation:

From Hooke's law of elasticity,

F = ke

F/e = k

F1/e1 = F2/e2

F2 = F1e2/e1

F1 = 10 lbf, e2 = 6 in, e1 = 4 in

F2 = 10×6/4 = 15 lbf

Work done (W) = 1/2F2e2

F2 = 15 lbf = 15×4.4482 = 66.723 N

e2 = 6 in = 6×0.0254 = 0.1524 m

W = 1/2×66.723×0.1524 = 5.084 J

The exact circumference of the circle is [tex]7 \frac{49}{150} k m[/tex]

The approximate circumference of the circle is [tex]7.33 k m[/tex]

Explanation:

The diameter of the circle is [tex]2 \frac{1}{3} \mathrm{km}[/tex]

Now, we shall find the circumference of the circle.

The formula to determine the circumference of the circle is given by

[tex]C=\pi d[/tex]

Where C is the circumference , [tex]\pi[/tex] is 3.14 and [tex]d=2 \frac{1}{3} \mathrm[/tex] is the diameter of the circle.

The exact circumference of the circle is given by

[tex]\begin{aligned}C &=\pi d \\&=(3.14)\left(2 \frac{1}{3}\right) \\&=(3.14)\left(\frac{7}{3}\right) \\&=\frac{21.98}{3}\end{aligned}[/tex]

Multiply both numerator and denominator by 100, we get,

[tex]C=\frac{2198}{300} \\C=\frac{1099}{150}[/tex]

Converting [tex]\frac{1099}{150}[/tex] into mixed fraction, we get,

[tex]C=7 \frac{49}{150}[/tex]

Thus, the exact circumference of the circle is [tex]7 \frac{49}{150} k m[/tex]

The approximate value of the circumference can be determined by dividing the value [tex]\frac{1099}{150}[/tex]

[tex]C=\frac{1099}{150}=7.327[/tex]

[tex]C=7.33km[/tex]

Thus, the approximate circumference of the circle is [tex]7.33 k m[/tex]

Answer:

263,606.9

Step-by-step explanation:

In 2004 the population in Morganton, Georgia, was 43,000.

(0, 43000)

The population in Morganton doubled by 2010

In 6 years the population is doubled (86000)

(6,86000)

[tex]A= a(b)^t[/tex]

Use (0,43000) in the above equation

[tex]A= a(b)^t\\43000= a(b)^0\\a=43000[/tex]

Now plug in (6,86000)

[tex]A= a(b)^t\\A= 43000(b)^t\\86000=43000(b)^6\\2=b^6\\b=\sqrt[6]{2} \\b=1.12[/tex]

[tex]A=43000(1.12)^t[/tex]

Now find out A when t=16 (2020)

[tex]A=43000(1.12)^t\\A=43000(1.12)^{16}\\A=263606.9[/tex]

If the growth rate from 2004 to 2010 continues, the expected population in Morganton, Georgia in 2020 would be around 172,000 as the population is doubling every 6 years.

The population of Morganton, Georgia in 2004 was 43,000 and it doubled by 2010 to 86,000. This shows a constant growth rate in which the population size doubles every 6 years. If this rate of growth remains consistent, the population of Morganton is expected to double again by 2020. Therefore, by 2020, the population of Morganton, Georgia could be around 172,000 people.

Line perpendicular to m is y =–4.

Distance from P to m is 5 units.

Solution:

Line m contains points (1, 1) and (5, 1).

Slope passing through two points formula:

[tex]$\text{slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

        [tex]$=\frac{1-1}{5-1}[/tex]

Slope = 0

Slope of the line perpendicular to the line m:

[tex]$\text{Slope}=\frac{-1}{\text{slope}}=0[/tex]

Equation of a line passing through one point and slope formula:

[tex]y-y_1=m(x-x_1)[/tex]

Here, m = 0 and P(2, –4)

[tex]$\Rightarrow y-(-4)=0(x-2)[/tex]

[tex]$\Rightarrow y+4=0[/tex]

[tex]$\Rightarrow y=-4[/tex]

⇒ y = –4

Equation of a line perpendicular to m and passing through P is y = –4.

Option C is the correct graph. Because it only has slope 0 and P(2, –4).

Point of intersection where line m and P meets is (2, 1).

Let us find the distance between the line m in the point (2, 1) and P(2, –4).

Distance formula:

[tex]\text {Distance}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

              [tex]=\sqrt{(2-2)^2+(-4-1)^2}[/tex]

              [tex]=\sqrt{25}[/tex]

              = 5

Distance = 5 units

Hence line perpendicular to m is y =–4.

Distance from P to m is 5 units.

Duku is 9 meters below the surface of the water, calculated by adding Duku's 5 meters above Kojo's position to Kojo's 14 meters below the surface.

The question asks about Duku's position relative to the surface of the water given Kojo is 14 meters below the surface and Duku is 5 meters above Kojo. To find Duku's position, subtract 5 meters (Duku's position above Kojo) from -14 meters (Kojo's position below the surface). Therefore, Duku's position relative to the surface of the water is -14 meters + 5 meters = -9 meters. This means Duku is 9 meters below the surface of the water.

Answer:

The value of the [tex]13^{th}[/tex] term is ≈ 1.

Step-by-step explanation:

A geometric sequence is a series of numbers where each term is computed by multiplying the previous term by a constant, r also known as the common ratio.

The formula to compute the [tex]n^{th}[/tex] term of a GP is: [tex]a_{n}=a_{1}\times r^{n-1}[/tex]

Here, a₁ is the first term.

It is provided that a₄ = 19625 and a₉ = 95.

Determine the value of a₁ and r as follows:

[tex]\frac{a_{4}}{a_{9}}=\frac{a_{1}r^{4-1}}{a_{1}r^{9-1}} \\\frac{19625}{95}= \frac{r^{3}}{r^{8}}r^{5}=\frac{95}{19625}\\ r=(\frac{95}{19625})^{1/5}\\=0.344[/tex]

The common ratio is, r = 0.344.

The value of a₁ is:

[tex]a_{4}=19625\\a_{1}\times(0.344)^{3}=19625\\a_{1}=\frac{19625}{0.040707584} \\=482096.898\\\approx482097[/tex]

The first term is, a₁ = 482097.

13th term of this geometric sequence is:

[tex]a_{13}=a_{1}\times r^{13-1}\\=482097\times (0.344)^{12}\\=1.3234\\\approx1[/tex]

Thus, the [tex]13^{th}[/tex] term is approximately equal to 1.

Answer:

The response does not seem reasonable.

Step-by-step explanation:

The current price of shorts is a sum of the original price plus profit. In this case, a simple formula is given:

Profit = Selling price  - Buying price

Therefore, the selling price can be anything less than $ 41.

Expressing the information in a linear equation gives x ≤ 41

where x is the buying price of the shorts.

To determine if David's answer that the original price of the shorts was $41 seems reasonable, we can use an equation to represent the situation. By solving the equation, we find that the original price of the shorts is $21.98, not $41.

To determine if David's answer that the original price of the shorts was $41 seems reasonable, we can use an equation to represent the situation. Let's assume the original price of the shorts is x dollars.

If the total cost of the T-shirt and shorts, including tax, is $22.45 as given, we can write the equation: x + 1.47 = 22.45.

Simplifying the equation, we subtract 1.47 from both sides: x = 21.98.

Therefore, the original price of the shorts would be $21.98, not $41. Hence, David's answer does not seem reasonable.

[tex]50x=750+30x[/tex]

Subtract 30x from both sides of the equation.

[tex]20 x=750[/tex]

Divide by 20 on both sides of the equation, we get

x = 37.5 (or) [tex]\frac{75}{2}[/tex]

Hence the value of x is 37.5 or [tex]\frac{75}{2}[/tex].
