Answers
Answer: The correct graph is the bottom left graph.
Step-by-step explanation:
Given function is f(x)=ceil(x+1)
To plot graph of f(x) in interval of(-3,3) :
ceil(x+1) is ceiling function
The output of ceil(x) is least integer greater than x
for example ceil(5.5)=6
For an interval of (-3,-2):
Take x=(-2.4)
x+1=(-1.4)
y=f(x)=ceil(x+1)=(-1)
Similarly,
For an interval of (-2,-1):
Take x=(-1.4)
x+1=(-0.4)
y=f(x)=ceil(x+1)=(0)
For an interval of (-1,0)
y=f(x)=1
For an interval of (0,1)
y=f(x)=2
For an interval of (1,2)
y=f(x)=3
For an interval of (2,3)
y=f(x)=4
Thus, The correct graph is the bottom left graph.

a. An equation that represents the situation is y = 9 x
b. The best Interpretation of the slope is " It costs $9 per hour to rent a kayak " ⇒ 2nd answer
c. It costs $45 to rent the kayak for 5 hours
Step-by-step explanation:
Proportional relationship means two quantities vary with each other
If y varies directly as x, then
y ∝ x y = k xk is called the constant of proportionality You can find k by using the initial values of x and yThe cost " y " in (dollars) to rent a kayak is proportional to the
number of hours " x " that you rent the kayak
∵ y ∝ x
∴ y = k x , where k is the constant of proportionality
∵ It costs $27 to rent the kayak for 3 hours
∴ y = 27 and x = 3
- Substitute these value in the equation above
∴ 27 = k (3)
- Divide both sides by 3
∴ 9 = k
∴ y = 9 x
a. An equation that represents the situation is y = 9 x
∵ The slope is the unit rate of the cost
∵ The slope = 9
∴ The unit rate is $9 per hour
b. The best Interpretation of the slope is " It costs $9 per hour to rent a kayak "
∵ y = 9 x
∵ x = 5 hours
- Substitute x by 5 in the equation above
∴ y = 9 (5) = $45

Final answer:
The equation representing the situation is y = 9x. The slope indicates that it costs $9 per hour to rent the kayak. For 5 hours of rental, the cost is $45.
Explanation:
If the cost (y) to rent a kayak is proportional to the number (x) of hours the kayak is rented, and it costs $27 to rent the kayak for 3 hours, we can use this information to write a linear equation that represents the situation. The cost is $9 per hour since $27 ÷ 3 hours = $9 per hour. Our equation is thus y = 9x.
For the interpretation of the slope, since we've determined the cost is $9 per hour, the correct interpretation of the slope is that it costs $9 per hour to rent the kayak.
To find out how much it costs to rent the kayak for 5 hours, we simply plug in x = 5 into our equation y = 9x. So, it costs y = 9 × 5 = $45 to rent the kayak for 5 hours.
The local appliance store is offering 15% off an entire purchase of $2,000 or more; or 30% off a single
item of $1,000 or more. Use the prices listed above to determine which offer will save the most
money on these appliances?
Answers
Answer:
The offer of 30% off a single item of $ 1000 or more will save most money on these appliances .
Step-by-step explanation:
Given as :
The purchase price = $ 2000
The offering discount = 15 %
Let The price of item after discount = x
So , x = ( $ 2000 ) - ( $ 2000 × 15 % )
Or, x = ( $ 2000 ) - ( $ 2000 × 0.15 )
Or, x = ( $ 2000 ) - ( $ 300 )
∴ x = $ 1700
Now, Again
The purchase price = $ 1000
The offering discount = 30 %
Let The price of item after discount = y
So , y = ( $ 1000 ) - ( $ 1000 × 30 % )
Or, y = ( $ 1000 ) - ( $ 1000 × 0.3 )
Or, y = ( $ 1000 ) - ( $ 300 )
∴ y = $ 700
Now, If we purchase two item at the cost price of $ 700 each , then it will cost as $ 700 × 2 = $ 1400
And for the same number of items at the cost price is $ 1700 after 15 % discount on list price of $ 2000 , So the second offer will save most .
Hence The offer of 30% off a single item of $ 1000 or more will save most money on these appliances . Answer
6. Emma uses 10 pages of paper when she writes anything. She uses an
additional 4 pages of paper every hour that she writes. Write an equation
that would show how many pages of paper she uses when writing.
Answers
Answer:

Step-by-step explanation:
Emma is guaranteed to use 10 pages when she writes something. Since you can't tell how many hours she has written, you use x to represent the hours she has spent writing. If she writes 4 pages every hour, that would be 4 × (hours spent writing) or 4x. Add 4x to the original guaranteed 10 pages she uses and you have your expression.

of the male fishes. How many female and male fishes in the tank?
(Set up the rational equation, and solve for x!) PLEASE HELP ME
Answers
Answer:
5 Male fishes, and 15 Female fishes
Step-by-step explanation:
We have two unknowns: The number of lady fishes (let's represent this number with "L"), and the number of male fishes (let's name this unknown number "M"). So now we need to create two equations to help us solve for these unknowns.
Use the actual sentences they give you to create the equations:
a) "75% of the total number of fishes are female"
Notice that the total number of fishes is the addition of the number of ladies plus the number of males; that is the total is "L+M". According to the sentence, 75% (which in math terms is written as "0.75") of this total number equals the number of lady fishes:
[tex]0.75 \,*\,(L+M)=L[/tex]
now we work a little the algebra indicated in this equation to simplify it a bit:
[tex]0.75 \,*\,(L+M)=L\\0.75\,L+0.75\,M=L\\0.75\,M=L-0.75\,L\\0.75\,M=0.25\,L\\L=\frac{ 0.75\,M}{0.25}\\L=3\,M[/tex]
which tells us that the number of lady fishes is 3 times thenumber of male fishes.
b) Now the second equation based on the words:
"Lady fishes are 5 more than twice the male fishes"
"Twice the male fishes" can be written as: "2M"
so now we write this sentence as:
[tex]L=2\,M+5[/tex]
Now we combine the two equations by using in the second one the replacement for "L" in terms of "M" that we found in the first equation (that is: "L = 3 M") , so we obtain an equation with just one unknown (M) and we can solve for it:
[tex]L=2\,M+5\\3\,M=2\,M+5\\3\,M-2\,M=5\\M=5[/tex]
Which tells us that the number of male fishes in the tank is "5".
We can use now our first simplified equation to find the number of lady fishes:
[tex]L=3\,M\\L=3\,(5)\\L=15[/tex]
So, there are 15 female fishes in the tank.

F is the force in Newtons
m is the mass in (kilograms)
a is the acceleration (in m/s^2)
Given,
m = 27

A local library bought 54 books. Some cost $32 each and some cost $44 each. The total cost of the books was $1,968. How many of the $32 books were purchased?
Answers
Answer:
Step-by-step explanation:
I think the answer is 34
To find the number of $32 books purchased, we can set up a system of equations. Solving the system using substitution, we find that the library purchased 34 of the $32 books.
Explanation:To solve this problem, we can set up a system of equations. Let's call the number of $32 books x and the number of $44 books y. We know that x + y = 54, since the library bought a total of 54 books. We also know that the total cost of the books is $1,968, which can be expressed as 32x + 44y = 1968. Now, we can solve this system of equations to find the value of x.
One way to solve this system is by substitution. Solving the first equation for x, we get x = 54 - y. Plugging this into the second equation, we have 32(54 - y) + 44y = 1968.
Expanding and simplifying, we have 1728 - 32y + 44y = 1968. Combining like terms, we get 12y = 240. Dividing both sides by 12, we find that y = 20. Plugging this back into the first equation x + 20 = 54, we get x = 34.
Therefore, the library purchased 34 of the $32 books.

► If the ratio of cars to trucks in a parking lot is 8 to 3 and there are 21 trucks, how many cars are there? I don’t know where to start I need help!! This needs to be shown full work on my college math class that’s a requirement!! Can anyone give me an explanation ASAP!!!
Answers
Answer:
So a ratio of 8:3 means for every 8 cars that is 3 trucks so we have the number of trucks which is 21 so what i did to find the answer was see how many times 3 went into 21 which is 7 times then you would take the 7 and times it by 8 and get 56 so there are 56 cars.
Step-by-step explanation:
Final answer:
To determine the number of cars, we use the ratio of cars to trucks (8 to 3) with the total number of trucks (21) to find the common multiplier. Multiplying the ratio number for cars (8) by the multiplier (7) gives us 56 cars in the parking lot.
Explanation:
Calculating the Number of Cars in a Parking Lot
To calculate the number of cars in the parking lot when we know the ratio of cars to trucks and the number of trucks, we can set up a proportion. Given that the ratio of cars to trucks is 8 to 3 and there are 21 trucks, we can represent the number of cars as 8x and the number of trucks as 3x, where x is the common multiplier for the ratio. Since we know there are 21 trucks, we can set 3x equal to 21 and solve for x:
3x = 21
Divide both sides of the equation by 3:
x = 21 / 3
x = 7
Now that we have the value of x, we can find the number of cars by multiplying the ratio number for cars (8) by x (7):
Number of cars = 8 x 7
Number of cars = 56
Therefore, there are 56 cars in the parking lot.
how long will it take for an investment to triple if it is compounded continuously at 12%
Answers
Answer:
9.694 years
Step-by-step explanation:
Let the investment is $P.
So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.
Let the time is y years.
So, from the formula of compound interest we can write
[tex]3P = P(1 + \frac{12}{100} )^{y}[/tex]
⇒ [tex](1 + \frac{12}{100} )^{y} = 3[/tex]
⇒ [tex](1.12)^{y} = 3[/tex]
Now, taking log both sides we get,
y log 1.12 = log 3 {Since, [tex]\log a^{b} = b \log a[/tex] }
⇒ 0.04922y = 0.477712
⇒ y = 9.694 years (Answer)

The volume of gas in a container is 125,000
liters, and the pressure is 1.2 atmospheres. Suppose the temperature remains constant, and the pressure changes to 1.6 atmospheres.
What is the new volume of the gas in liters?
Answers
Answer:
93750 L
Step-by-step explanation:
P1V1 = P2V2
1.2 atm*125000L = 1.6 atm* V2
V2 = 93750 L
The new volume of the gas is 93750 liters.
Given,
The volume of gas in a container is 125,000 liters.
The pressure is 1.2 atmospheres.
Suppose the temperature remains constant.
The pressure changes to 1.6 atmospheres.
We have to find the new volume of the gas.
What is the ideal gas law equation?The equation is given by:
PV = nRT
Where P is the pressure of the gas.
V is its volume.
n is the number of moles of the gas.
T is its kelvin temperature.
R is the ideal (universal) gas constant.
Let the initial volume and pressure of the gas be [tex]V_{1}[/tex] and [tex]P_{1}[/tex].
The final volume and pressure of the gas be [tex]V_{2}[/tex] and [tex]P_{2}[/tex].
We have,
[tex]V_{1}[/tex] = 125000 litres.
[tex]P_{1}[/tex] = 1.2 atmospheres.
Since temperature remains constant.
[tex]P_{1} V_{1}[/tex] / nR = T and [tex]P_{2} V_{2}[/tex] / nR = T
We can write as:
[tex]P_{1} V_{1}[/tex] / nR = [tex]P_{2} V_{2}[/tex] / nR
[tex]P_{1} V_{1}[/tex] = [tex]P_{2} V_{2}[/tex]
Putting the values we get,
[tex]P_{1} V_{1}[/tex] = [tex]P_{2} V_{2}[/tex]
1.2 x 125000 = 1.6 x [tex]V_{2}[/tex]
[tex]V_{2}[/tex] = (1.2 x 125000) / 1.6
= 93750 litres.
Thus the new volume of the gas is 93750 liters.
