Answer:
A= 28.27 ft²
Step-by-step explanation:
if its trying to find area for a circle then we use the formula A=πr²
A=π(3)²
A= 28.27 ft²
Answer:
the answer is 18.85ft
Step-by-step explanation:
the question is asking you to find the circumfrance (the outside of the circle) so the formula you would use is:
C = 2πr
input the values you have into the formula
C= 2 x π x 3
(the radius is the distance between the very centre of the circle to the outside. it gives you the diameter which is the distance all the way across the circle so just half the diameter, which gives you a radius of 3)
put that into your calculator and youll get the answer
C= 18.8495559215
(i rounded the answer to two decimal places = 18.85ft)
A kite and its tail total 48 ft in length. the tails is 7 times the length of the body. How long is the kite's tail?
Answer:
42 ft
Step-by-step explanation:
body = x
tail = 7x
x + 7x = 48
8x = 48
Divide both sides by 8
x = 6
Tail
7x = 7(6)
7x = 42

Luanne and Fiona each made a salt water solution. Luanne mixed 3 cups of salt with every gallon of water. Fiona mixed 2 cups of salt with every 3 gallons water. Which of these statements is true?
Answer:
See Explanation
Step-by-step explanation:
Given
Luanne
[tex]Salt = 3\ cups[/tex]
[tex]Gallon = 1[/tex]
Fiona
[tex]Salt = 2\ cups[/tex]
[tex]Gallon = 3[/tex]
The question is incomplete, as the options are not given.
However, possible comparison that can be made are
(a) The unit amount of salt
(b) Whose solution is more concentrated with salt
(a) The unit amount of salt
To do this, we divide the amount of salt by the number of gallons.
[tex]Unit = \frac{Salt}{Gallon}[/tex]
For Luanne
[tex]Unit = \frac{3}{1}[/tex]
[tex]Unit = 3 cups/gallon[/tex]
For Fiona
[tex]Unit = \frac{2}{3}[/tex]
[tex]Unit = 0.67cups/gallon[/tex]
(b) Whose solution is more concentrated with salt
By comparing the result in (a)
We have:
[tex]Unit = 3 cups/gallon[/tex] --- Luanne
[tex]Unit = 0.67cups/gallon[/tex] --- Fiona
Luanne unit amount implies that there are 3 cups in every gallon of water;
Fiona unit amount implies that there are 0.67 cups in every gallon of water;
[tex]3 >0.67[/tex]
Hence, Luanne solution is more concentrated with salt

Sabrina has gone to work the last 50 days. On 28 of those days, she arrived before 7:30 A.M. On the rest of the days, she arrived after 7:30 A.M. What is the experimental probability that she will arrive at work before 7:30 A.M. On her next day of work? What is the experimental probability that she will arrive after 7:30 A.M.?
Answer:
Prob (Arrive before 7.30) = 14 / 25 ; Prob (Arrive after 7.30) = 11 / 25
Step-by-step explanation:
Prob (Arrive before 7.30) = No. of days before 7.30 arrival / Total work days
= 28 / 50 = 14 / 25
Prob (Arrive after 7.30) = No. of days after 7.30 arrival / Total work days
= (50 - 28) / 50 = 22 / 50 = 11 / 25
or , 1 - Prob (Arrive before 7.30) = 1 - 14/25 = (25 - 11) / 25 = 11/ 25

Formula of a triangle:
B(base) x H(height) x 1/2(basically dividing by 2)
Write your question here (Keep it simple and clear to get the best answer)striangle has vertices A(2;5); B(1;-2) and C(-5;1). Determine:(a) the equation of the line BC. (b) The equation of the perpendicular line from A to Bc
(a) y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex]
(b) y = 2x + 3
Step-by-step explanation:
(a) The equation of a line given by points M(x₁, y₁) and N(x₂, y₂) is given by:
y - y₁ = m(x - x₁) -------------------(i)
Where;
m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = slope or gradient of the line ---------------(ii)
Given points on the triangle are:
A(2,5)
B(1,-2)
C(-5,1)
To find the equation of line BC, we use the formulas in equations (i) and (ii) where the points of the line are B(1,-2) and C(-5,1) and;
x₁ = 1
y₁ = -2
x₂ = -5
y₂ = 1
==> First get the gradient using equation (ii) as follows;
m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = [tex]\frac{1 - (-2)}{-5 -1}[/tex]
m = [tex]\frac{3}{-6}[/tex]
m = [tex]\frac{-1}{2}[/tex]
==> Now, use equation (i) to find the equation of the line as follows;
y - (-2) = [tex]\frac{-1}{2}[/tex](x - 1)
y + 2 = [tex]\frac{-1}{2}[/tex](x - 1)
Multiply both sides by 2
2(y+2) = -1 ( x - 1 )
2y + 4 = -x + 1
2y = -x + 1 - 4
2y = - x - 3
y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex]
Therefore, the equation of the line is y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex]
(b) To find the perpendicular line from A to BC, note that
i. two lines are perpendicular if they meet at 90°
ii. the general equation of a line could also be written as y = mx + c where m is the slope and c is the intercept.
iii. when one line has a slope of m, then a perpendicular line to that line will have a slope of [tex]\frac{-1}{m}[/tex]
The equation of line BC is y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex].
This means that BC has a slope of [tex]\frac{-1}{2}[/tex]
A perpendicular line from A to BC will have a slope of 2.
Now to get the equation of this perpendicular line from A(2, 5) to BC, we use the general equation of a line given in equation (i)
where;
m = 2
x₁ = 2
y₁ = 5
Substitute these values into equation (i)
y - 5 = 2(x - 2)
Solving by simplification gives;
y - 5 = 2x - 2
y = 2x + 3
Therefore, the equation of the perpendicular line is y = 2x + 3
Rays PQ and PS are perpendicular to each other.
What is the measure of LRPS plzzzzz
Answer:
m<RPS = 53 degrees
Step-by-step explanation:
Find the diagram attached
From the diagram shown;
m<QPR + m<RPS = 90
Given that;
m<QPR = x
m<RPS = x+16
Substitute into the formula;
m<QPR + m<RPS = 90
x+x+16 = 90
2x+16 = 90
2x = 90-16
2x = 74
x = 74/2
x = 37degrees
Get m<RPS;
Since m<RPS = x+16
m<RPS = 37 + 16
m<RPS = 53 degrees

Doug worked out for 256 minutes.
Doug has an enemy named Cathy
Cathy worked out a total of 4 hours and 15 minutes.
Who worked out more? What was the difference in minutes?
Answer:
Step-by-step explanation:
Cathy worked 4 hours.
4 hours = 4 * 60 = 240 minutes
She worked an additional 15 minutes which brings her total up to 255.
Doug worked 1 minute longer than Cathy.
Answer:
a.) Doug worked more. b.)The difference is one minute.
Step-by-step explanation:
CAN BE DONE DIFFERENTLY
Cathy has 4 & 15 minutes, since each hour is 60 minutes we can multiply 60 by 4.
60
x4
240
Now adding the 15 it'll be 255.
DOUG WORKED MORE.
DIFFERENCE IS 1 MINUTE.

Determine the area of a circle whose diameter is 8 in Use 3. 14 for TT Enter your answer in the box. Round to the nearest hundredth, if necessary. A= blank inches squared
Answer:
50.24
Step-by-step explanation:
Area = pi*r^2
r = diameter/2
r = 4
Area = pi*4^2
Area = 3.14*16
Area = 50.24
Answer:
Step-by-step explanation:
The area A of a circle of radius r is A = πr², where π is often approximated by 3.14.
Here, with the circle diameter being 8, we figure the radius to be half that, or 4.
Then the area of this circle is A = (3.14)(4 in)², or
A = 50.24 in²

A small business wants to meet the minimum medical loss ratio required. If projections show that the business will pay out an average of $8,900 per policy holder in health care claims, what is the minimum average premium they should charge per policy holder?
Answer:
$7120 or $7565 is the minimum average premium they should charge per policy holder
Step-by-step explanation:
Small business can charge 80-85% of the total value of the policy as premium.
In this case the spending per policy holder is $8900
Hence, per policy holder has to pay a premium of
80-85% of $8900
$7120 or $7565 is the minimum average premium they should charge per policy holder
