Which statement(s) can be interpreted from the equation for a real estate value, V(C)=228,000(1.03)' where V(C) represents the value of the real estate and t represents the time in years?
The equation is an exponential growth equation.
The equation is an exponential decay equation
The equation is neither exponential decay nor exponential growth
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
$228,000 represents the initial cost of a real estate that appreciates 30% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 3% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 30% per year over the course of t years
Answer:
The equation is an exponential growth equation.
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
Step-by-step explanation:
the correct equation is: V(C)=228,000(1.03)^t
Hi, to answer this question we have to apply an exponential growth equation:
A = P (1 + r) t
Where:
p = initial cost
r = growing rate (decimal form)
t= years
A =cost after t years
Before applying the formula:
1.03 = 1+r
1.03-1 =r
0.03=r
Replacing with the values given:
A = 228,000 (1+ 0.03)^t
r = 0.03
Since r is in decimal form, we have to multiply it by 100
0.03 x 100 = 3% appreciation per year

A clothes shop has some special offers.
T-shirts are buy one get one free and jumpers are 3 for 2.
The normal price of a T-shirt is £3.50 and the normal price of a jumper is £16.
How much does it cost to get 3 jumpers and 8 T-shirts using this offer as appropriate?
Answer:
£142 for 3 jumpers and 8 T-shirts
Step-by-step explanation:
Since the T-shirts cost £3.50 each and they are buy one get one free, when you buy 8 T-shirts you only pay for 4 of them.
£3.50(4) = £140 for the 8 T-shirts
Since you bought 3 jumpers with a buy 3 for £2 sale, the 3 jumpers cost £2.
Add the amount of money all together to find the total cost of the T-shirts and jumpers.
£140 + £2 = £142

Answer:
2. BD=14m BC=10, CD=4
3. x=43
4. x=14
Step-by-step explanation:
2. The segment BD should be equal to 14, as then problem would be impossible. Then,
BD=14
BC=10 (given)
CD=14-BC=14-10=4
3. Angle CBD is equal to angle DBA, because BD bisects the angle CBA.
So, if we substitute the measures of the angles,
55 =x+12
55-12=x
x=43 degrees
4. Angle QRT+angle TRS=180 degrees because they are both on a straight line, which equals 180 degrees.
So, if we substitute with the measures of the angles,
3x+5+10x-7=180 degrees
13x-2=180
x= 14
Mary earns $5 per hour as a waitress. Last week she took home her regular earnings of $5 per hour plus $186 in tips for a total of $301. Which equation can be used to find how many hours, h, Mary worked last week?
A.
$301 = $5h + $186
B.
$301 = $186h + $5
C.
$301 = $186h - $5
D.
$301 = $5h - $186
Answer:
A
Step-by-step explanation:
Let's set hours as h.
We know that she earns 5 dollars an hour. If, for example, she worked 2 hours, she would have earned 2*5=10 dollars. This is 5h.
Next, we know that she got 186 dollars in tips. Tips means that she earned extra money, so therefore, the equation is 5h+186, or A

this is incorrect because 12 does not equal -12, so there is no solution
Beccas dad told her that she needs to practice piano for two hours this week so far she has practiced 20 minutes on Monday a half an hour on Tuesday and 15 minutes on Wednesday how much longer does she need to practice?
Answer:
Step-by-step explanation:
She needs to practice piano for 2 hours this week:
Lets add the time she played the piano so far:
Monday + Tuesday + Wednesday
Which is
20 + 30 (half an hour) + 15
= 65 minutes
In which 2 hours is equal to 120 minutes
So,
120 - 65 = 55
She needs to practice for 55 more minutes in this week

65
%
salt. She wants to obtain
40
ounces of a mixture that is
60
%
salt. How many ounces of each solution should she use?
Answer:
We need 8 ounces of solution A and 32 ounces of solution B.
Step-by-step explanation:
We are given that a scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt.
She knows that Solution A is 40% salt and Solution B is 65% salt.
First condition states that she wants to obtain 40 ounces of a mixture that is 60 % salt, that means;A + B = 40
B = 40 - A ------------ [Equation 1]
Second condition states that Solution A is 40% salt and Solution B is 65% salt, that means;[tex]0.4 \text{A}+0.65 \text{B}=0.60 \times 40[/tex]
[tex]0.4 \text{A}+0.65 \text{B}=24[/tex]
[tex]0.4 \text{A}+0.65 (40- \text{A})=24[/tex] {from equation 1}
[tex]0.4 \text{A}+26- \text{0.65A}=24[/tex]
[tex]\text{0.65A} - 0.4 \text{A}=26-24[/tex]
[tex]\text{0.25A} =2[/tex]
A = [tex]\frac{2}{0.25}[/tex] = 8 ounces
Now, putting value of A in equation 1, we get;
B = 40 - A
B = 40 - 8 = 32 ounces
Hence, we need 8 ounces of solution A and 32 ounces of solution B.

Find the volume of each composite figure. Round to the
nearest tenth. (Hint) Find the Volume of both figures, then additional step is required to find your answer.
Answer:
1209.06 cubic feet
Step-by-step explanation:
use the formula for the volume of a cylinder and the volume of a rectangular prism, and then plug the values into that
The volume of the composite figure consisting of a cylinder and a rectangular prisms to the nearest tenth is 1209.1ft³.
What is a cylinder and a rectangular prism?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi ( π = 3.1415 )
A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles.
The volume of a rectangular prism is expressed as;
V = w × h × l
Where w is width, l is length and h is the height
From the diagram, the figure consist of a cylinder and a rectangular prism.
For the cylinder;
Radius r = 4ftHeight h = 4ftVolume of the cylinder V_c = ?For the rectangular prism;
Width w = 14ftLength l = 12ftHeight h = 6ftVolume of the rectangular prism V_r = ?Volume of the cylinder.
V_c = π × r² × h
V_c = 3.1415 × (4ft)² × 4ft
V_c = 3.1415 × 16ft² × 4ft
V_c = 201.1ft³
Volume of the rectangular prism.
V_r = w × h × l
V_r = 14ft × 6ft × 12ft
V_r = 1008ft³
Now, the volume of the composite figure will be;
V = V_c + V_r
V = 201.1ft³ + 1008ft³
V = 1209.1ft³
Therefore, the volume of the composite figure consisting of a cylinder and a rectangular prisms to the nearest tenth is 1209.1ft³.

Eight friends decided to try white-water rafting on a nearby river. They rented four two-person rafts; one was yellow, one was green, one was red, and one was blue. They selected partners for the four rafts and agreed on a destination at the end of a white-water run.
1. Phil and Cook, who were in the same raft, arrived at the destination without incident, but they were not the ones who finished first. 2. The red raft capsized and did not finish; the green raft was first to finish the white-water run. 3. O’Brien and LeRoy were not on the same raft. 4. Paul and Wilson finished last on their raft. 5. Fortunately, Henry is a good swimmer, and he helped his partner, Hughes (whose first name is not Walt), get to shore. They were able to recover their capsized raft, but declined to finish the white-water run. 6. Frank was the first to select a raft, and he picked the yellow one. He and Hawley were on the second raft to finish the white-water run. 7. Alan and Hughes were on the same raft; they were the first to finish the whitewater run. 8. LeRoy and Smith completed the run and were not in last place. 9. After their nearly tragic capsizing experience, Don and his partner, Gladstone, vowed not to set foot in another raft. 10. Alan did not care that he and his partner finished last; he was just glad they made it.
(a) Based on the following statements, one of which is false, what is the first name (Alan, Don, Frank, Henry, LeRoy, Paul, Phil, or Walt) and surname (Cook, Gladstone, Hawley, Huges, O’Brien, Sands, Smith, or Wilson) of each of the friends? (b) Which were partners on the four rafts? (c) What color raft was used by each?
Answer:
Leroy Sands & Walt Smith - greenFrank Cook & Phil Hawley - yellowPaul O'Brien & Alan Wilson - blueHenry Gladstone & Don Hughes - redStep-by-step explanation:
First of all, it is convenient to choose the false statement.
We note that statements 7 (Alan is first) and 10 (Alan did not finish) are contradictory, so one of them must be false. Statement 5 has Henry & Hughes together, so is not consistent with statement 7 (Alan & Hughes). So, statement 7 is inconsistent with two other statements, thus must be the false one.
__
The attached table shows how we parsed the statements. An "O" signifies a combination that must occur; and "X" signifies one that cannot occur. We have used "-" to fill the spaces that are inconsistent with the locations of "O". The red letters are deduced from the others.
The first complete set we found was Henry & Hughes (Don & Gladstone) who were in the (red) capsized raft and did not finish. The second complete set we found was Phil & Cook (Frank & Hawley) who were in the (yellow) raft that finished second. We know Paul & Wilson (Alan & Partner) finished last, so Phil & Cook could not have been Paul and Wilson. Finally, O'Brien and Leroy were not on the same boat, so Paul must be Paul O'Brien and Leroy must be Leroy Sands.

Answer:
I believe its $66.04. If it asked for the total, then it would have been 66.04 + 508, which it did not ask. So try $66.04.
Step-by-step explanation:
508 is the actual price and 13% of 508 is 66.04.
Answer:
$66.04
Step-by-step explanation:
This is an example of a percentage of an amount.
The formula for the percentage of an amount is : [tex]\frac{Percentage}{100} *amount[/tex]
To work this out you would first need to convert the percentage of 13% into a decimal. You can do this by dividing the percentage of 13 by 100, this gives you 0.13. This is because percentages are out of 100.
To work out the price of shipping and handling you would need to multiply the amount of $508 by the decimal of 0.13, this gives you $66.04. This is because we are working out 13% of $508.
1) Divide 13 by 100.
[tex]13/100=0.13[/tex]
2) Multiply 0.13 by 508.
[tex]0.13*508=66.04[/tex]
