Answer: The circumference of the plate = 51.86 inches.

Step-by-step explanation:

Given : The radius of a round plate = 8.25 inches

Formula: circumference of a circle = [tex]2\pi r[/tex] , where r = radius of circle .

Then, the circumference of the plate [tex]=2\times\dfrac{22}{7}\times8.25[/tex]   [ [tex]\pi=\dfrac{22}{7}[/tex] ]

[tex]=51.857142857\approx51.86\ \text{inches}[/tex]

Hence, the circumference of the plate = 51.86 inches.

Step-by-step explanation:

In order to find the average, I must add the numbers and divide them by 4.

2.34 + -2/7 + -0.45 + 3/8 = 2.55071428571

2.55071428571/4 = 0.6376785714275

Answer: 6 ft and 2 ft

Step-by-step explanation:

Answer:

6ft and 2ft

Step-by-step explanation:

8ft board ÷ 2 pieces = 4ft each

4ft and 4ft boards. But one of them is longer by 2ft so:

4ft - 2ft = 2ft

4ft + 2 ft = 6ft

So, one piece is 2ft and the other piece is 6ft

Answer:

x=3

Step-by-step explanation:

6x - 2 = x + 13

subtract 1x from both sides

5x - 2 = 13

isolate the 5x by adding 2 to both sides

5x = 15

finnaly devide both by 5

x = 3

Answer:

28.63%

Step-by-step explanation:

Given data:

correlation between funds = 0.308

Risk-free rate = 0.042

Expected return rate = 0.11

Calculate the standard deviation of the new portfolio

standard deviation of portfolio = ( weight of risky assets )* (standard deviation of optimal risky portfolio )

weight of risky assets = (expected return - risk-free rate) / ( expected return of optimal portfolio - risk-free rate ) ( calculated using excel spreadsheet)

= 0.9696

Standard deviation of optimal risky portfolio = 29.525489% ( calculated using excel spreadsheet )

hence standard deviation of portfolio that would an expected return of 11%

= 0.9696 * 29.525489%

= 28.63%

Equation of straight line is y=mx+c

choose any two points on straight line

for me I choose:(-3,11) and (3,-1)

use these two points to find gradient,m.

m= (-1-11)/(3-(-3))

m= -2

now, y=-2x+c

choose any point on the straight line

I choose point (3,-1)

sub the point into the equation to find c

-1=-2(3)+c

c=5

equation: y=-2x+5

Answer:

Please check explanations for answer

Step-by-step explanation:

Let’s have two points (5,10) and (15,20)

1. Let’s find the slope of these two points

Mathematically, the slope can be calculated using the formula;

m = (y2-y1)/(x1-x2)

So m = (20-10)/(5-15) = 10/-10 = -1

The error here is the formula used in calculating the slope

The formula should be;

m = (y2-y1)/(x2-x1) and not x1-x2

2. To calculate the slope correctly, we have;

m = (y2-y1)/(x2-x1)

So the slope will be;

m = (20-10)/(15-5) = 10/10 = 1

In the point slope form, the equation can be represented as;

y-y1 = m(x-x1)

Let’s use the point (5,10)

y- 10 = 1(x-5)

The above is the point slope form

using one of the points and the correct slope of the line

Step-by-step explanation:

The temperature increase in degrees Fahrenheit that is equivalent to a temperature increase by 10 degrees Celsius is 50 degree Fahrenheit.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.

As we know:

F = 32 + 1.8C

We have C = 10 degree Celsius

F = 32 + 1.8×10

F = 50 degree Fahrenheit

Thus, the temperature increase in degrees Fahrenheit that is equivalent to a temperature increase by 10 degrees Celsius is 50 degree Fahrenheit.

Answer:

The students can make 70 pieces of ornament from the 5 pieces of Bristol board from the cupboard.

Step-by-step explanation:

Since each student takes 14 of a piece of Bristol board to make an ornament, and we have 5 pieces of Bristol board in the cupboard, this implies that we require 1 Bristol board makes 14 pieces of ornament. Therefore 5 pieces of Bristol Board will make 5 × 14 pieces of ornament = 70 pieces of ornament.

So, the students can make 70 pieces of ornament from the 5 pieces of Bristol board from the cupboard.

Answer:

t = 1/2 ÷ 1/4

t = 2 hours

Step-by-step explanation:

Time spent watching movies = 1/2 of an hour

This accounts for 1/4 of the total time thei spend at mount rushmore.

1/2 = 1/4t

Where t = total time they spent at mount rushmore (hours)

1/2 = 1/4t

Determine the equation to find t

t = 1/2 ÷ 1/4

= 1/2 × 4/1

= 4 / 2

= 2

t = 2 hours

Answer: 10 inches

Step-by-step explanation:

1. multiply 14 by 2 to get 28.

2. Subtract 28 from 48 to get 20

3. Divide 20 by 2 to get 10

your answer is 10

Answer: 10 inches

Step-by-step explanation:

a worksheet is usually a rectangle

the formula for the perimeter of a rectangle is 2x + 2y

Lets say that x = the length and y = the height

it already gives you x = 14, so plug everything in to find y

P = 2x + 2y

48 = 2(14) + 2y

48 = 28 + 2y            plug in x = 14 and multiply

20 = 2y                    subtract 28 from both sides to get this

y = 10                       then divide both sides by 2 to get the answer

Answer:

1). R ≥ 75

2). 1.45R + 0.65C ≤ 200

Step-by-step explanation:

Total amount with Jada = $200

Let the number of roses purchased by her = R

Number of people = 75

Cost of R roses at the rate of $1.45 each = 1.45R

Along with roses she purchased carnations = C

Cost of carnations = $0.65 each

Total cost of Carnations = $0.65C

1). Inequality to represent the constraint that every person takes home at least  one rose,

R ≥ 75

2). Inequality representing the cost constraint will be,

    1.45R + 0.65C ≤ 200

This can be determined by  using inequality concept. Hence inequality to represent the constraint that every person takes home at least  one rose will be, R ≥ 75 and for the cost constraint will be, 1.45R + 0.65C ≤ 200.

Given:

Jada has $200 to spend on flowers.Roses cost $1.45 and  carnations cost $0.65 each and 75 people  attending the event can take home at least one rose.

Jada has total amount  = $200

 Let the number of roses purchased by Jada = R roses

Total number of people who will attending  event  = 75 people

Therefore,cost of R roses at the rate of $1.45 each = 1.45R

Along with roses Jada purchased carnations = C

Now the cost of each carnations= $0.65

Therefore,cost of C carnations at the rate of $0.65 each = 0.65C

1). Inequality to represent the constraint that every person takes home at least  one rose will be,

     R ≥ 75

2). Inequality representing the cost constraint will be,

      1.45R + 0.65C ≤ 200
