A round plate has a radius of 8.25 inches. What is the circumference of the plate?
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.

writing equations of lines
Step-by-step explanation:
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

They go to the cupboard and find 5 pieces of Bristol board. How many ornaments can they make?F Bristol board. How many ornaments can they make?
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: 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

The perimeter of a worksheet is 48 inches. The worksheet is 14 inches long. How tall is it?
inches
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

Jada has $200 to spend on flowers for a school celebration. She decides that the only
flowers that she wants to buy are roses and carnations. Roses cost $1.45 each and
carnations cost $0.65 each. Jada buys enough roses so that each of the 75 people
attending the event can take home at least one rose.
1. Write an inequality to represent the constraint that every person takes home at least
one rose.
2. Write an inequality to represent the cost constraint.
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

Alonzo earns 8% commission on vacuum cleaner sales. This past month, Alonzo sold 70 units at $150.00 each. How much did Alonzo make in commissions for the past month? Explain how you found your answer.
Answer:
Made $840 in commissions for the past month.
Step-by-step explanation:
sales = 70 * 150 = 10500
commission = .08 * 10500 = 840
Answer:
$840
Step-by-step explanation:
8% = 0.08
.08 * 150 = 12 per unit sold
12 * 70 = 840.00

While on vcacation, kevin and his family visit mount rushmore in south dakota. They watcha movie in the vistor center for 1/2 of an hour. This accounta for 1/4 og the toatl time the spend at mount rushmore. What equation can you use to find the total amount of time t kevin's family spends at mount rushmore
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
A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a sure rate of 4.2%. The probability distributions of the risky funds are: Expected Return Standard Deviation Stock fund (S) 12 % 33 % Bond fund (B) 5 % 26 % The correlation between the fund returns is .0308. Suppose now that your portfolio must yield an expected return of 11% and be efficient, that is, on the best feasible CAL. a. What is the standard deviation of your portfolio? (Do n
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%

2- Use the same two points from the error analysis question above and show how to calculate the slope correctly. Then, use the correct slope and one of the points to write the equation in point-slope form of the line. Show all work!
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
