Answer:
She has an initiall amount of 6 hours, so if T is the amount of time that passed since she rented the boat, the inequality that describes this system is:
0≤ T ≤ 6
This means that she can use the boat from 0 hours to 6 hours, here we are allowing the intermediate values because, of course, she can return the boat earlier than in the given time.
From this we have that the maximum time left that she has can be written as:
x + T = 6
so if T = 3h, meaning that 3 hours passed, she has:
X + 3 = 6
x = 6 - 3 = 3
3 hours left.

VolumeSurface area==========================================
Explanation:
The volume is the amount of stuff that a container can hold on the inside, while the surface area is the amount of stuff that goes on the outside of the container (eg: the amount of paint or wallpaper). In the case of wallpapering a room, we're actually doing the inner walls rather than the outside walls; however, it's the same concept. The surface area only deals with the surface and we want to find out how much area we have to cover. That way we can know how much wallpaper to buy. For problem 1, he needs to know the volume so he can find out how much trash each can would be able to hold. The greater the volume, the larger the bin. For instance a small wastebasket would have a small volume compared to a large waist high heavy duty trash container.

Sara is planning on fully renovating her kitchen. She figures that this will cost a total of $25,750. If Sandra already has $21,400 saved up, what annual interest rate
compounded semiannually would Sara need to earn in order to have the required
funds if she invests her money for 2.5 years?
Answer:
She needs an annual interest rate of 7.54%.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
She figures that this will cost a total of $25,750.
This means that [tex]A = 25750[/tex].
Sandra already has $21,400 saved up
This means that [tex]P = 21400[/tex].
Semianually compunding, 2.5 years.
This means that [tex]n = 2, t = 2.5[/tex]
What interest rate?
We have to find r. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]25750 = 21400(1 + \frac{r}{2})^{2*2.5}[/tex]
[tex](1 + 0.5r)^5 = \frac{25750}{21400}[/tex]
[tex]\sqrt[5]{(1 + 0.5r)^5} = \sqrt[5]{\frac{25750}{21400}}[/tex]
[tex]1 + 0.5r = (\frac{25750}{21400})^{\frac{1}{5}}[/tex]
[tex]1 + 0.5r = 1.0377[/tex]
[tex]0.5r = 0.0377[/tex]
[tex]r = \frac{0.0377}{0.5}[/tex]
[tex]r = 0.0754[/tex]
0.0754*100% = 7.54%
She needs an annual interest rate of 7.54%.

Answer:
1.Make the circle open
2.put the dot on 5
3. change direction
Step-by-step explanation:
A solid dot on a number line graph indicates that the given number should be included as a possible solution, whereas an open dot indicates that the given number cannot be a solution. For example, if you graph x > 7, you place an open dot at 7.

What is the measure of ∠E?
Answer:
80 degrees
Step-by-step explanation:
first we need to find the measure of F, we know a straight line equals 180 so we subtract 120 from 180
180-120=60
then add that to angle D
60+40=100
and all triangle angles add up to 180 so subtract 100 from 180
180-100=80
80 is your answer

Answer:
The common difference is: -0.75
Step-by-step explanation:
Given

Required
The common difference
From the graph, we have:
[tex]T_n: -3.75, -4.5, -5.25, -6, -6.75, -7.5, -8.25, -9.[/tex]
The x coordinates represent the position of each term
The common difference (d) is:
[tex]d = T_n - T_{n-1}[/tex]
Let [tex]n = 2[/tex]
[tex]d = T_2 - T_{2-1}[/tex]
[tex]d = T_2 - T_1[/tex]
So, we have:
[tex]d = -4.5 - (-3.75)[/tex]
[tex]d = -4.5 +3.75[/tex]
[tex]d = -0.75[/tex]
Find a polynomial f(x) of degree 3 that has the following zeros. -5, 8, 2 Leave your answer in factored form
Answer:
f(x) = (x+5)(x-8)(x-2)
Step-by-step explanation:
If we know the zeros, the polynomial is of the form
f(x) = (x-a)(x-b)(x-c) where a,b,c are the zeros
f(x) = (x - -5)(x-8)(x-2)
f(x) = (x+5)(x-8)(x-2)
Answer:
f(x) = (x + 5)(x - 8)(x - 2)
Step-by-step explanation:
Given a polynomial with zeros x = a , x = b , then the corresponding factors are
(x - a) and (x - b)
The polynomial is a product of the factors, that is
f(x) = (x - a)(x - b)
Here the zeros are x = - 5, x = 8, x = 2, then corresponding factors are
(x - (- 5)), (x - 8), (x - 2) , that is
(x + 5), (x - 8), (x - 2) and the polynomial is
f(x) = (x + 5)(x - 8)(x - 2)
The lateral areas of two similar cylinders are 196π in^2 and 324π in^2. The volume of smaller cylinder is 1715π in^3. Find the volume of the larger cylinder.
Answer:
3,645 π in³
Step-by-step explanation:
the ratio of the radius :
r1 : r2 = √196 : √324
= 14 : 18
= 7 : 9
the ratio of the volume:
v1 : v2 = 7³ : 9³
= 343 : 729
so, the volume of the larger cylinder =
729/343 x 1715π = 3,645 π in³
Answer:
since the cylinders are similar their area and volume will be proportional
[tex]\frac{lateral\:area \:of \:smaller \:cylinder}{laternal\: area \:of \:larger\: cylinder}=\frac{volume \:of\: larger\: cylinder}{volume \:of \:larger \:cylinder}[/tex]
[tex] \frac{196π}{324π}=\frac{1715π}{V}[/tex]
V=1715π*324π/126π
V=4410πin³
the volume of the larger cylinder is 4410πin³.

Explain the meaning of probability. What does it mean if an event has a probability of 0? Give an example. What does it mean if an event has a probability of 1? Give an example. What does it mean if an event has a probability of 1/2? Give an example. (LONG ANSWERS ONLY)
Answer:
If an event has a probability of 0 it means that it is impossible. For example when they say there is 0% of rain. It is very unlikely it is going to rain. If an event has a probability of 1 it means that it is certain. For example, if they say there is a 100% chance it is going to rain. It is very certain that it's going to rain. If an event is 1/2 then it means there it is likely as it is unlikely. For example, if they say there is a 50% chance of rain. Then it might not rain, but there is a chance that it might rain as well.
Step-by-step explanation:
Hope this helps!
Probability can simply be defined as the chances of an event a, occuring with respect to event b, with respect to event n, given an nth number of possible outcomes.
Probability can be calculated using the following expression:
[tex] \frac{freq \: of \: event \: n}{freq \: of \: total \: number \: of \: events} [/tex]
When an event has a probability of 0, it means that by no chance or condition will the event be true. For example, the probability of a person who is a boy has 0 probability that he is a girl.
When an event has a probability of 1, it means that with every chance or condition, the event will be true. For example, the probability that a person who is a boy has a probability of 1 that he is a boy.
An event that has a probability of 1/2 means that the event could either return a probability of 0 or 1 on different chances or conditions. For example, the probability of a fuetus whose gender is not known has a probability of 1/2 for being a boy and 1/2 for being a girl.

The lateral area of a cube is 36 square inches. How long is each edge?
Answer:
8
3
Step-by-step explanation:
Volume of a cylinder = πr²h
Volume = 3207
Radius, r
Height, = 5
320π = π * 5 * r²
320 = * 5 * r²
320 = 5 * r²
r² = 320/ 5
r² = 64
r = 8 m
The lateral surface area of a cube is
LSA = 4s²
Where s = edge length
36 = 4s²
s² = 36/4
s² = 9
s =. sqrt(9)
s = 3
