Answer:
a) R = 3.6
b) A = 2
Step-by-step explanation:
From the above question, we are told that:
R is inversely proportional to A.
Mathematically =
R ∝ 1/A
= R = k × 1/A
R = k/A
Where k = Constant of Proportionality
We are given
R= 12 when A= 1.5
Hence, we find k
R = k/A
k = RA
k = 12 × 1.5
k = 18
a) Work out the value of R when A= 5.
We have our formula
R = k/A
k = 18
A = 5
R = 18/5
R = 3.6
b) Work out the value of A when R= 9
We have our formula
R = k/A
k = 18
9 = 18/A
Cross Multiply
9A = 18
A = 18/9
A = 2

All tickets to a musical have the same cost. A group bought 7 tickets and paid a total of $100. Write an equation that can be used to determine the cost c in dollars for each ticket.
Answer:
$14.28
Step-by-step explanation:
Given data
Lets say the cost of one ticket is x dollars
so
hence for 7 tickets the cost c can be given as
c= 7x
100= 7x
x= 100/7
x= 14.28
Hence the cost of a ticket is $14.28

Answer:
Felicia, these questions are tough for a lot of reasons, so it makes sense to me that nobody is giving you the right answers. here is a right one :)
Step-by-step explanation:
1st we need a strategy. brainstorm :P we are given the cost of material for boxes in area, we are asked how much 12 boxes would cost. let's find the area of the material for one box multiply that by the given cost. and then multiply that by 12 for the total cost. seem good? Yes there are other good ways to solve this problem if you're thinking that. this is just how I'm arbitrarily choosing to solve it.
1) surface area of prism box
1a) triangles on ends
1/2* b*p ( I think 6.2 is P for you, not positive about that)
1/2*6.4*6.2= 19.84
1b) flat sides
6.4*25 =160 ( this is B )
1c) add up the 5 sides
160*3 + 19.84 * 2 = 839.68 [tex]cm^{2}[/tex]
2) find the cost on 1 box
839.68 [tex]cm^{2}[/tex] * $0.0001 = 0.8397
about $0.84
3) find the cost for 12 boxes
0.8397 * 12 = 10.076
about $10.08
try those answers :)

Rewrite the following equation in slope-intercept form.
y + 3 = }(x + 6)
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
Slope-intercept form is
y = mx + b
We want to get the y by itself on one side of the equation.
0 = 18x + 6y – 2
First let's subtract 6y from both sides.
-6y = 18x – 2
Next let's divide both sides by -6.
y = (18 / -6)x - (2 / -6)
y = -3x + 1/3
...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)

-14=3x-y
2y=-8x
final answer: how many solutions are there??
Answer:
One solution: (-2, 8)Step-by-step explanation:
2y = -8x ⇒ y = -4x
-14 = 3x - y
-14 = 3x - (-4x)
-14 = 3x + 4x
-14 = 7x
x = -2
y = -4(-2) = 8
The solution: (-2, 8)

28 Matty ings 9 km/hr Identify the
find each angle m1,m2,m3
Answer Angle 1= 97 angle 2= 83 and angle 3= 62
Step-by-step explanation:
To find angle one all you have to do is add your interior angles of the other triangle togther which always equals your exterior angle which is angle 1 making it equal to 97. To find angle 2 we know that the two angle are supplemetary meaning it doesn't matter what order they are in they always equal 180. to find the measure of angle 2 you subtract angle one 97 from 180 which equals 83 the measure of angle 2. Now to find the measure on angle 3 is the sum of the two other interior angles minus 180 degrees which is always the total sum of interior angles on a triangle. 83 plus 35 equals 118 which is the sum of the two know interior angles then you subtract that sum from 182 degrees equaling 62 degrees the measure of angle 3.
I hope this helps but don't know if this right.

New Orleans averages 77% humidity in the mornings, but it decreases by 20% in the afternoon. What is the average relative humidity in the afternoon in New Orleans? (enter a percent rounded to the tenths place)
Answer: 61.6%
Step-by-step explanation:
The afternoon humidity average is 20% of the morning average.
The morning average is 77% so the afternoon average must be:
= Morning average * ( 1 - percentage decrease)
= 77% * (1 - 20%)
= 77% * 80%
= 61.6%
If a person's eye level is h meters above sea d level and he can see kilometers to the horizon, then d= 3.57 h. Suppose the person's eye level is 10.24 meters above sea level. How far can he see to the horizon
Answer: 36.56 km
Step-by-step explanation:
If the eye level is h meters above the sea level
The person can see up to d kilometer horizontally
The relation between d and h is
[tex]\Rightarrow d=3.57 h[/tex]
For h=10.24 m, d is
[tex]\Rightarrow d=3.57\times 10.24=36.556\ km[/tex]

What will a $160,000 house cost 8 years from now if the price appreciation for homes over that period averages 7% compounded annually?
Answer:
Step-by-step explanation:
We will use the A=P*(1+r/n)^nt formula
P = 160,000
R = the rate 7%
N= the times compounded. Since it is annually it is 1
T = 8 years
Filling in the information...
A = 160,000 x (1 + .07)^1*8
= 160,000 x 1.07^8
= 160,000 x 1.71818617983
= 274909.788773
Round up as needed.

what is the area in square centimeters of the figure below
Answer:
A. 6.96 square cm
Step-by-step explanation:
A = 5.8 x 2.4 x 1/2
A = 5.8 x 1.2
A = 6.96
Hope that helps!
Answer:
6.96
Step-by-step explanation:
The area of a triangle is base times height over 2. The base is 5.8 and the height is 2.4. The product of these numbers is 13.92. We now have to divide this by 2. This gives our final answer of 6.96
