A tank can hold a maximum of 400 gallons of water. The volume of water when pumping water into the tank can be determined by the function f (m) = 12.5m + 25 where m is the number of minutes that the pump is running and f(m) is the volume of gallons of water in the tank. If the tank must maintain a minimum of 25 gallons of water, which inequality represents the domain of this situation?
(Hint: The variable f(m) is like "y" and m is like "x")
0 < m < 400
30 < m < 400
25 < m < 400
0 < m < 30
Inequalities help us to compare two unequal expressions. The inequality that represents the domain of this situation is 0<m<30.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that the volume of the tank should be between 400 gallons of water to 25 gallons of water. While the function of the volume of the water is given as,
f(m) = 12.5m + 25,
Now to know the value of m for which the volume of water in the tank is 400 gallons.
[tex]f(m) = 12.5m + 25\\\\400=12.5+25\\\\375=12.5m\\\\m = 30[/tex]
Also, the value of m for which the volume of the water in the tank is 25 gallons is,
[tex]f(m) = 12.5m + 25\\\\25=12.5+25\\\\0=12.5m\\\\m = 0[/tex]
Hence, the inequality that represents the domain of this situation is 0<m<30.

Which are equivalent ratios to 2:3?
Check all that are true.
10:16
8:12
6:9
9:12
4:6
Answer:
8:12 6:9 4:6
Step-by-step explanation:
Divide each ratio by 2:3 and check if both numbers on either side of : are the same
For example:
8:12 divided by 2:3 = 4:4
Answer:
8:12, 6:9, and 4:6
Step-by-step explanation:
Equivalent ratios are any ratios that represent the same when they are simplified. All the ratios above simplify to 2:3. When the 8 and 12 of 8:12 are both divided by 4, the result is 2:3. When the 6 and 9 in 6:9 are both divided by 3, the result is 2:3. When the 4 and 6 in 4:6 are both divided by 2, the result is 2:3. The ratios 10:16 and 9:12 cannot be simplified to 2:3, and therefore are not correct answers.

You are comparing the costs of a certain model of ladder at a hardware store and online. The sale information can be found below.
PART A: Calculate the final cost of the ladder at each of the stores. Include the proportion(s) or equations(s) you needed to reach your answer.
PART B: Suppose the hardware store decides to offer 10% off the cost of the ladder (but still keep the 6% tax) and the online store decides to offer free shipping and handling (but still keep the 6% tax). In this situation, which store offers the better final cost? Include the proportion(s) or equations(s) you needed to reach your answer.
Answer:
Part A:
Hardware Store = $371Online Store = $355.20Part B: The hardware store is cheaper.
Step-by-step explanation:
Part A:
At the hardware store, the ladder is 350 plus 6% tax. To solve this you would multiply 350 by 1.06 tax. Then you would get 371. Online, the ladder is 320 plus 6% tax and 5% shipping. To solve this you would multiply 320 by 1.11 (tax and shipping combined). Then you would get 355.20.
Part B:
To solve the cost of the ladder at the hardware store, you would need to first multiply 350 by 0.9 for the 10% discount. That would get you 315. Then add the 6% tax to get 333.90. To solve for the online ladder, you would need to multiply 320 by 1.06 (6%), and get an answer of 339.20. This means that the hardware store is cheaper.
Answer
Step-by-step explanation: How to find the percentage from the total value?
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form
16.24%
So, we can rewrite it as;
16.24 / 100
16 and 24/100 or 16 6/25
So the percent as a fraction is 16 6/25
We are given that;
Cost of ladder= $320
Sales tax of shipping and handling is 5% and 6%
Off on hardware= 10%
Now,
PART A:
At the online store, the ladder costs $320, and the sales tax is 6% of $320, which is:
$320 x 0.06 = $19.20
The shipping and handling is 5% of $320, which is:
$320 x 0.05 = $16
So the total cost of buying the ladder online is:
$320 + $19.20 + $16 = $355.20
At the physical store, the ladder costs $350, and the sales tax is 6% of $350, which is:
$350 x 0.06 = $21
So the total cost of buying the ladder at the physical store is:
$350 + $21 = $371
Therefore, buying the ladder online would be cheaper, with a total cost of $355.20.
PART B:
If the hardware store is offering 10% off the price of the ladder, the cost of the ladder would be:
$350 x 0.1 = $35 off
$350 - $35 = $315
So the total cost of buying the ladder at the physical store with the discount would be:
$315 + $18.90 (6% sales tax) = $333.90
If the online store is offering free shipping and handling, the total cost of buying the ladder online would be the same as the cost of the ladder:
$320 + $19.20 (6% sales tax) = $339.20

Cole buys a new laptop for $335. He makes a down payment of $50 and pays the rest in 6 equal monthly payments, p. What equation represents the relationship between the cost of the laptop and Cole’s payments?
Answer:
f(p) = 6p + 50
Step-by-step explanation:
f(p) = 6p + 50
where f(p) is the total money for the laptop ($335) and p is the monthly payment.
If you wanted to plug in the total cost of the laptop the equation would be 335 = 6p + 50.
A zoo keeper was in charge of determining the population of meerkats at the zoo. He observed the meerkats and noted 8 of them and the special markings are on their face. The next day he went back out and observed the meerkats again. Out of the 20 that he saw, 4 of them were the same meerkats that he saw yesterday. How many meerkats can he assume are living at the zoo?
Answer:
16
Step-by-step explanation:
The zoo-keeper saw 8 special meerkats the day before and then only saw 4 special meerkats out of 20 the day after so 4 - 20 = 16.

one platter has 6 veggie wraps, 12 turkey wraps and costs 64.50 another platter has 8 veggie wraps 8 turkey wraps and costs $56
Which system of equations represents the situation if x represents the cost of a veggie wrap and y represents the cost of a turkey wrap?
A.12x + 6y = 568x + 8y = 64.50
B.6x + 12y = 64.508x + 8y = 56
C.x + 2y = 64.50x + y = 56
D.6x = 64.508y = 56
Answer: $3.25
Step-by-step explanation: The computation of the cost of a veggie wrap is shown below:
Let us assume the veggie strap be x
And the turkey wrap be y
Now the equations are
6x + 12y = $64.50
x + 2y = $10.75
8x + 8y = $56
x + y = 7
Now
x + 2y = $10.75
x + y = $7
y = $3.75
So x = $7 - 3.75
= $3.25
So, the correct option is option (B).

Linear simultaneous equation:Simultaneous linear equations are the system of two linear equations in two or three variables that are solved together to find a common solution. The simultaneous linear equation is represented as follows:
[tex]a_1x+b_1y=c_1\\a_2x+b_2y=c_2[/tex]
It is given that,
[tex]x[/tex] represents the cost of a veggie wrap and [tex]y[/tex] represents the cost of a turkey wrap.
Now, using the first part of the given question we get,
[tex]6x+12y=64.50...(1)[/tex]
Again in the second part of the given question is 8 veggies wraps 8 turkey wraps and costs $56 then we get the equation as,
[tex]8x+8y=56...(2)[/tex]
Then from equations (1) and (2) we get the equation as,
[tex]6x+12y=64.50\\8x+8y=56[/tex]

Answer:
x = 120, y = 160
Step-by-step explanation:
I like to use the elimination strategy in this type of problem.
You need to get one of the terms on the right side of the equation equal to and opposite another term on the right side of the other equation. For example, I'm going to make the y term of the first equation equal and opposite the y term of the second equation by multiplying the entire first equation by -1.5.
-1.5 * (x + y) = (280) * -1.5
2.5x + 1.5y = 540
The new equations are (only the first one changed):
-1.5x - 1.5y = -420
2.5x + 1.5y = 540
-----------------------------------
x = 120
Then plug this back into one of the equations.
(120) + y = 280
y = 160
You can check by plugging these into the other equation to make sure they are correct.
Which of the following operations would you perform on both sides of the given equation to solve it? Check all that apply.3x - 10 = 2x + 6
