Ground beef costs $2.19 per pound. Which equation best
represents y, the total cost of x pounds of ground beef?
A. x = 2.19y
B. x= 2.19+y
C. y = 2.19x
D. y = 2.19 + x
Answer:
C
Step-by-step explanation:
When looking at the total cost of x pounds of something when the cost is per pound, you multiply the two numbers. Because y is the total cost, you want that as the answer that you are looking for, so it will be by itself when looking at the two sides of the equation. This means that answer c is the only one correct. A/B cannot be unless you were looking for the number of pounds, and you were dividing y (total cost) by 2.19 (cost per pound). D does not work because you are just adding how many pounds you have to the cost per pound.
Solve the system of equations:
y=5x+3
2x+6y=50
What is the equation?
Answer:
y - 4 = (1/3)(x - 9) or x - 3y = -3
Step-by-step explanation:
Here we're told that the slope is 1/3 and that (9, 4) is a point on the line. Use the point-slope formula y - k = m(x - h). Substitute 4 for k, 9 for h and 1/3 for m:
y - 4 = (1/3)(x - 9) (point-slope formula)
3y - 12 = x - 9 (standard form of the same equation) = >
-12 + 9 = x - 3y, or x - 3y = -3 (standard form)

A model of the ocean floor takes up 2/5 of the space in an aquarium. If 3/8 of the model is coral, what fraction of the space in an aquarium is taken up by coral?
Answer:
Fraction = [tex]\dfrac{3}{20}[/tex]
Step-by-step explanation:
Given that,
A model of the ocean floor takes up 2/5 of the space in an aquarium.
3/8 of the model is coral.
We need to find the fraction of the space in an aquarium is taken up by coral. So, it can be done as follows :
[tex]x=\dfrac{3}{8}\times \dfrac{2}{5}\\\\x=\dfrac{3}{20}[/tex]
So, the fraction of space taken by coral is [tex]\dfrac{3}{20}[/tex] in an aquarium.

Three different accounts are described below. Order the accounts according to their values after 10 years, from greatest to least.
You deposit $950 in an account that earns 9% annual interest compounded daily.
= You deposit $1000 in an account that earns 8% annual interest compounded daily.
= You deposit $1000 in an account that earns 9% annual interest compounded semiannually.
= You deposit $1000 in an account that earns 10% simple interest.
Answer:
`1. You deposit $950 in an account that earns 9% annual interest compounded daily.
2.You deposit $1000 in an account that earns 8% annual interest compounded daily.
3. You deposit $1000 in an account that earns 9% annual interest compounded semiannually.
Step-by-step explanation:
Trick question, number 3 says semiannually so it is only twice a year, so it is the least. In math papa or any algebra calculator, put in the two equations and compare which is greater, in this case, y = 950(1.09)^10 is greater than y=1000(1.08)^10
Accounts according to their values after 10 years, from greatest to least. are Account 3, Account 1, Account 2 and Account 4.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The formula for daily compounding is:
[tex]A = P(1 + r/n)^{nt}[/tex]
where A is the future value,
P is the principal amount,
r is the annual interest rate,
n is the number of times the interest is compounded per year, and t is the time in years.
When we deposit $950 in an account that earns 9% annual interest compounded daily.
A = 950(1 + 0.09/365)³⁶⁵⁰
= $2,436.24
Deposit $1000 in an account that earns 8% annual interest compounded daily.
A = 1000(1 + 0.08/365)³⁶⁵⁰
= $2,223.97
Deposit $1000 in an account that earns 9% annual interest compounded semiannually.
A = 1000(1 + 0.09/2)²⁰
= $2,471.52
Deposit $1000 in an account that earns 10% simple interest.
The formula for simple interest is:
A = P(1 + rt)
where A is the future value, P is the principal amount, r is the annual interest rate, and t is the time in years.
Using this formula, we get:
A = 1000(1 + 0.10(10))
= $2,000
Now we can order the accounts from greatest to least based on their future values after 10 years:
Account 3: $2,471.52
Account 1: $2,436.24
Account 2: $2,223.97
Account 4: $2,000
Hence, accounts according to their values after 10 years, from greatest to least. are Account 3, Account 1, Account 2 and Account 4.

A restaurant gets extremely busy during lunch (11:00 A.M. to 2:00 P.M.) and is trying to decide whether it should increase the number of waitresses from two to three. What considerations would you look at to determine whether simulation should be used to make this decision?
Answer:
Step-by-step explanation:
The two main considerations that you should take into account would be each employee's wage and the number of tables that they can handle simultaneously and efficiently. This would allow you to create a simulation in order to determine if adding an extra waitress would be the best option. Adding an extra waitress would be a worthwhile decision if it divides the workload evenly so that all the waitresses have sufficient tables to handle while also not being too much, and if the extra labor is bringing in more money than it costs.

When you go swimming the pressure in your ears varies directly with the depth at which you swim. At 10 feet, the pressure is about 4.3 pounds per square inch (psi). a) Write the variation function. b) Predict the pressure at 50 feet. c) It is unsafe for amateur divers to swim where the pressure is more than 65 psi. How deep can an amateur swimmer safely swim (round to the nearest thousandth)
Answer:
(a) [tex]p = 0.43d[/tex]
(b) [tex]p = 21.5[/tex]
(c) [tex]d = 151.163[/tex]
Step-by-step explanation:
Given
Variation: Direct
Represent ear pressure with p and depth with d.
So, we have:
[tex]p\ \alpha\ d[/tex]
[tex]d =10[/tex] when [tex]p =4.3[/tex]
Solving (a): Write a variation
We have:
[tex]p\ \alpha\ d[/tex]
Write as an equation
[tex]p = kd[/tex]
Where: k is the constant of variation
[tex]d =10[/tex] when [tex]p =4.3[/tex]
So, we have:
[tex]4.3 = k * 10[/tex]
Make k the subject
[tex]k = \frac{4.3}{10}[/tex]
[tex]k = 0.43[/tex]
Substitute 0.43 for k in [tex]p = kd[/tex]
[tex]p = 0.43d[/tex]
Solving (b): Pressure at 50 feet
Substitute 50 for d in [tex]p = 0.43d[/tex]
[tex]p = 0.43 * 50[/tex]
[tex]p = 21.5[/tex]
The pressure is 21.5 pounds per square
Solving (c): The safe depth
The safe depth stops at a pressure of 65psi.
Substitute 65 for p in [tex]p = 0.43d[/tex]
[tex]65 = 0.43 * d[/tex]
Make d the subject
[tex]d = \frac{65}{0.43}[/tex]
[tex]d = 151.162790698[/tex]
[tex]d = 151.163[/tex] -- approximated
The safe distance for an amateur is 151.163ft

What is 8x times x?
Answer:
8x²
Step-by-step explanation:
Whenever it's multiplication, you would count how many x's there are and raise the x to the power of the number of x's.
The multiplication of 8x and x is 8x^2.
When we have to do multiplication,
We have given 8x and x.
What is the meaning of multiplication?Multiplication is defined as calculating the result of repeated additions of two numbers.
you would count how many x's there are and
Raise the x to the power of the number of x's.
and that is
[tex]=8\times x\times x[/tex]
There are two x therefore we have
[tex]=8x^2[/tex]
Therefore the multiplication of 8x and x is 8x^2.
