Write an equation to represent the relationship. Then solve the equation.
Six times a number plus 4 is the same as the number minus 11.

Answer: 6,845.9, or to whole number 6,846

Step-by-step explanation:

The age of the bones from the skeleton of s fish is 2000 years.

The formula to be used for calculation of age is-

ln (N/No) = - kt, where N/No represents remaining time, k represents constant of proportionality and t refers to the age or time period.

The remaining time = 100 - 22

Remaining time = 78% or 0.78

Keep the values in mentioned formula to find the time.

ln 0.78 = - 0.000124t

Keeping the value of ln 0.78 on Left Hand Side of the equation

- 0.248 = - 0.000124t

Negative sign will be cancelled as it is present on both sides of the equation

t = 0.248/0.000124

Performing division on Right Hand Side of the equation

t = 2000

Hence, the age is around 2000 years.

If the bucket is allowed to fall, then its linear acceleration is 8.687 m/s^2.

From the given question,

We have to solve, if the bucket is allowed to fall, then its linear acceleration

Mass of Pulley(M)= 0.692 kg

Radius of pulley(r)= 0.131 m

Mass of bucket(m)= 2.70 kg

Net torque on pulley,

[tex]\Sigma[/tex] r = rT = Iα

T = Iα/r

T= tension on string(connecting pulley and bucket)

I= moment of inertia of pulley

α= angular acceleration of pulley

linear acceleration of bucket(a),

a = rα

α = a/r

Pulley is disc shaped so

I = 1/2 Mr^2

Now, T= Iα/r = (1/2 Mr^2) (a/r)/r

T = 1/2 Ma

Now considering the motion of bucket

ma = mg-T

ma = mg-1/2 Ma

ma+1/2 Ma = mg

a = m/(m+1/2 M) g

Now putting the value

a = (2.70)×9.8/ (2.70+1/2 (0.692))

After solving

a = 8.687 m/s^2

If the bucket is allowed to fall, then its linear acceleration is 8.687 m/s^2.

The material that she has left after the cut of 1/2 yard of the material is 2/5 yards left

While I show you how to solve this problem, I would like to highlight some of the words and how they convert into a mathematical equation.

"She cut 1/3 yard off the material."

 This means you multiply whatever you are starting with by 1/3.

 So in this case Mineko begins with 3/5 yards.

 So,

3/5 • 1/3 = 1/5

She used 1/5 yard to make the pillow.

This will translate to Mineko having left

Therefore 3/5-1/5

The subtended arc is 2.14 times as long as the circle's radius.

What is radius of circle?

A circle or sphere's radius is any line segment that connects the object's center to its perimeter in classical geometry; in more contemporary usage, it also refers to the length of those line segments. The word "radius" is derived from Latin and means "ray" as well as "the spoke of a chariot wheel."

Given:

A circle with a radius 7 cm long is centered at an angle's vertex, and the angle's rays subtend an arc length of 15 cm along the circle.  

The radius of the circle is 7 and length of the subtend are is 15 cm. The required value is given by:

Subtended arc / Radius = 15 / 7 = 2.14

Therefore, option (e) is the correct answer.

Hence, the subtended arc is 2.14 times as long as the circle's radius.

Given that,

The combined length and girth of a priority mail package cannot exceed 171 inches, according to postal standards.

We have to find calculate the size of the largest volume, cylindrical container that can be sent via priority mail.

We know that,

Let

Length= Breadth =x

Height=y

Volume can be written as

V=x²y

Now,

Combined length and girth is

7x+y=171

y=171-7x

V(x)=x²(171-7x)

V(x)=171x²-7x³

Differentiating with respect to x.

V'(x)=343x-21x²

The maximum value

V'(x)=0

343x-21x²=0

7x(49-3x)=0

x=0

and

49-3x=0

3x=49

x=49/3

Once again differentiating with respect to x.

V''(x)=343-42x

V''(x)=343-42(0)=343>0(min)

V''(x)=343-42(49/3)=-343<0(max)

The maximum volume is

Vmax=V(49/3)=(49/3)(171-7(49/3))

The given expression can be simplified to obtain the quotient and remainder as 3x + 4 and -4 respectively.

The polynomial p(x) divided by the other polynomial g(x) gives remainder r(x) and quotient as q(x) such that degree of r(x) is not greater than g(x).

The given expression is (3x²+ 22x + 27)/(x+6).

The division can be done as follows,

First take the quotient as 3x so that that the remainder is,

3x²+ 22x - 3x(x + 6)

= 4x

Now, the new dividend is 4x + 6.

Take the quotient as 4 to get the remainder as,

4x + 6 - 4(x + 6)

= -18

It cannot be further divided because the degree of -18 is less than x + 6.

Which implies that the quotient is 3x + 4 and the remainder is -18.

Jane's share in the profit as per the amount invested by her is $39,375.

A ratio shows us the number of times a number contains another number.

Given that Capital balances were $100,000 for John, $75,000 for Sally and $225,000 for Jane. Therefore, the ratio of the capital invested by three can be written as,

John : Sally : Jane = $100,000 : $75,000 : $225,000

John : Sally : Jane = 4 : 3 : 9

Now, the profit will be shared as per the capital invested, therefore, as per the capital invested. Thus, we can write,

4x + 3x + 9x = $70,000

16x = $70,000

x = $70,000 / 16

x = $4,375

Further, Jane's share can be written as,

Jane's share = 9x

                     = 9 × $4,375

Answer:

Step-by-step explanation:To calculate the total cost of the cement manufacturing company, you need to consider the unit variable cost, the commission, and the fixed costs.

First, calculate the total variable cost per day by multiplying the unit variable cost by the number of tons of cement produced per day: $80/ton * 5000 tons/day = $400,000/day

Then, calculate the total commission cost by multiplying the total variable cost by the commission rate: $400,000/day * 5% = $20,000/day

Next, calculate the total fixed cost per day by dividing the monthly fixed cost by the number of days in a month: $12,000/month / 30 days/month = $400/day

Finally, add the total variable cost, the total commission cost, and the total fixed cost to calculate the total cost per day: $400,000/day + $20,000/day + $400/day = $420,400/day

To calculate the break-even revenue, divide the total cost by the difference between the sales price and the unit variable cost, then multiply by the number of tons of cement sold per day: ($420,400/day) / ($150/ton - $80/ton) * 5000 tons/day = $600,000/day

This means that the cement manufacturing company needs to generate at least $600,000 in revenue per day in order to break even.

P---> Future value of an annuity stream

PMT---->Dollar amount of each annuity payment

r -->Interest rate (also known as discount rate)

n--->Number of periods in which payments will be

We have given that

The plot of normal distributions A and B

A has the larger standard deviation

Standard Deviation

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

The name standard deviation for SD came from Karl Pearson. I would guess no more than that he wanted to recommend it as a standard measure. If anything, I guess that references to standardization either are independent or themselves allude to SD.

Mean

In statistics, the mean is one of the measures of central tendency, apart from the mode and median. Mean is nothing but the average of the given set of values. It denotes the equal distribution of values for a given data set. The mean, median and mode are the three commonly used measures of central tendency.

Normal Distribution

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graphical form, the normal distribution appears as a bell curve.
