In a certain chemical, the ratio of zinc to copper is 3 to 11. A jar of the chemical contains 473 grams of copper. How many grams of zinc does it contain?
Answer:
[tex]\large \boxed{\text{129 g}}[/tex]
Step-by-step explanation:
We can use ratio and proportion to solve this problem.
Let x = the mass of Zn
[tex]\begin{array}{cccl}\dfrac{\text{Zn}}{\text{Cu}} & = & \dfrac{3}{11} & \\\\\dfrac{x}{473} & = & \dfrac{3}{11} & \text{Substituted the mass of Cu}\\\\x & = & \dfrac{3\times473}{11} &\text{Multiplied each side by 473} \\\\ & = &\mathbf{129} & \text{Simplified}\\\end{array}\\\text{The mass of Zn is $\large \boxed{\textbf{129 g}}$}[/tex]
Check:
[tex]\begin{array}{rcl}\dfrac{129}{473} & = &\dfrac{3}{11} \\\\\dfrac{3}{11} & = & \dfrac{3}{11} \\\end{array}[/tex]

catherine is paying off a $2400 loan by making equal payments over a 12-month period until the loan is paid. express the amount of debt remaining as a function of time in months
Answer:$200 per month is spent.
Step-by-step explanation:
$2400 divided by 12 = $200
The amount of debt remaining as Catherine pays off her $2400 loan over 12 months is expressed by the function D(t) = 2400 - 200t, where t is the time in months.
Explanation:Catherine is paying off a $2400 loan by making equal payments over a 12-month period until the loan is paid. To express the amount of debt remaining as a function of time in months, let's denote the amount of debt remaining as D(t), where t is the time in months.
Since she is making equal payments over 12 months, the total amount she needs to pay each month is $2400 divided by 12 months, which is $200 per month. Therefore, the function that represents the amount of debt remaining at any time t is given by : D(t) = 2400 - 200t
This linear function shows that for each month that passes, $200 is subtracted from the original loan amount of $2400, representing the payments made towards the loan. Thus, after t months, the amount of debt remaining is calculated by subtracting $200 times the number of months from the initial loan amount.

4x+y=5
Solve linear systems by Multiplying
Step-by-step explanation:
The given system of linear equations:
x - 2y = 8 ........ (1)
and 4x + y = 5 ........ (2)
To find, the values of x and y = ?
Multiplying equation (2) by 2, we get
2(4x + y) = 5 × 2
⇒ 8x + 2y = 10 ........ (3)
Adding equations (1) and (3), we get
x - 2y + (8x + 2y) = 8 + 10
⇒ x - 2y + 8x + 2y = 8 + 10
⇒ 9x = 18
⇒ x = 2
Put x = 2 in (1), we get
2 - 2y = 8
⇒ 2y =2 - 8
⇒ 2y = - 6
⇒ y = - 3
∴ x = 2 and y = - 3
y=11 + x
5x+2y= -6

$216.00.
$219.00.
Answer:
$219.00.
Step-by-step explanation:
January 1, 10 units @ $8 (10 x 8) = $80
January 18, 50 units @ $9 (50 x 9) = $450
February 20, 20 units @ $11 (20 x 11) = $220
March 15, 10 units @ $12 (10 x 12) = 120
Ending Inventory = 19 unit
Ending Inventory = (10 x12) + (9 x 11) = $219
Answer:
$219.00 (or $220.00 because it's closest option to $219.00)

Step-by-step explanation:
the function that gives the deer population \( P(t) \) on the reservation t years from now is:
[tex]\[ \boxed{P(t) = 170 \times (1.30)^t} \][/tex]
To write a function that gives the deer population [tex]\( P(t) \)[/tex] on the reservation t years from now, where the population is increasing at a rate of 30% per year, we'll use the formula for exponential growth:
[tex]\[ P(t) = P_0 \times (1 + r)^t \][/tex]
Where:
- [tex]\( P(t) \)[/tex] is the population after t years,
- [tex]\( P_0 \)[/tex] is the initial population (in this case, 170),
- r is the annual growth rate (in decimal form), and
- t is the number of years.
Given that the population is increasing at a rate of 30% per year, we have [tex]\( r = 0.30 \)[/tex].
Substituting the given values into the formula, we get:
[tex]\[ P(t) = 170 \times (1 + 0.30)^t \][/tex]
Simplifying further:
[tex]\[ P(t) = 170 \times (1.30)^t \][/tex]
Therefore, the function that gives the deer population \( P(t) \) on the reservation t years from now is:
[tex]\[ \boxed{P(t) = 170 \times (1.30)^t} \][/tex]
The complete Question is given below:
There are 170 deer on a reservation. The deer population is increasing at a rate of 30% per year. Write a function that gives the deer population P(t) on the reservation t years from now.

(A person bought a water
tank of circular base having the radius 10.5 m and height
21 m for the use of his community from the 'Gyani Tank
Factory'. If the upper part of the tank is semi spherical,
how many litre of water will be contained in the tank?)
Answer:
About [tex]9,693,180\ liters[/tex]
Step-by-step explanation:
we know that
The volume of the tank is equal to the volume of a cylinder plus the volume of hemisphere
so
[tex]V=\pi r^{2}h+\frac{2}{3}\pi r^{3}[/tex]
where
[tex]r=10.5\ m\\h=21\ m\\\pi=3.14[/tex]
substitute
[tex]V=(3.14)(10.5)^{2}(21)+\frac{2}{3}(3.14)(10.5)^{3}[/tex]
[tex]V=7,269.885+2,423.295=9,693.18\ m^3[/tex]
Convert to liters
[tex]1\ m^3=1,000\ L[/tex]
therefore
The volume is equal to
[tex]9,693.18(1,000)=9,693,180\ liters[/tex]
Which is the most accurate measurement of 1 pound? (Remember, there are 16 ounces in a pound
Answer:
16 ounces
Step-by-step explanation:
The answer is option C. 16 ounces.
The most accurate measurement of 1 pound would be 16 ounces, because, by definition, there are 16 ounces in 1 pound.
Among the options provided:
A. 6 ounces: This is less than 1 pound.
B. 20.099 ounces: This is more than 1 pound.
C. 16 ounces: This is equal to 1 pound.
D. 10 ounces: This is less than 1 pound.
So, the most accurate measurement of 1 pound is 16 ounces.
One pound is most accurately measured as 16 ounces. This is because the imperial system defines one pound as equivalent to 16 ounces.
The question is:
Which is the most accurate measurement of 1 pound? (Remember, there are 16 ounces in a pound.)
A. 6 ounces

a) [tex]\frac{dy}{dx} = \frac{1-3lnx}{x^4}[/tex]
b) [tex]\frac{dy}{dx} = \frac{-2}{3\sqrt[3]{1-x} }[/tex]
Explanation:
a) [tex]y=\frac{lnx}{x^3}[/tex]
[tex]y = \frac{lnx}{\sqrt[3]{x} }[/tex]
[tex]y = lnx. x^-3[/tex]
Differentiating the above equation in terms of x
[tex]\frac{dy}{dx} = \frac{1}{x} \times x^-3 - 3lnx\times x^-^4\\\frac{dy}{dx} = \frac{1}{x^4} - \frac{3lnx}{x^4} \\\frac{dy}{dx} = \frac{1-3lnx}{x^4} \\[/tex]
b) [tex]y = \sqrt[3]{1-x^{2} }[/tex]
Differentiating the above equation in terms of x
[tex]y = \sqrt[3]{(1-x)^{2} } \\\frac{dy}{dx} = (1-x)^\frac{2}{3} \\\frac{dy}{dx} = \frac{2}{3}\times (1-x)^\frac{-1}{3} \times -1\\\frac{dy}{dx} = \frac{-2}{3\sqrt[3]{1-x} }[/tex]
Thus,

determine whether the realtionship between the circumference of a circle and its diameter is a direct variation. if so, identify the constant of porportionatlity. justify your response
Step-by-step explanation:
Let the radius of a circle be r
The circumference of a circle is(C) [tex]=2\pi r[/tex]
[tex]=\pi d[/tex] [∵2r =d= diameter]
Therefore [tex]C = \pi d[/tex]
Since the value of [tex]\pi[/tex] is always constant. Here the diameter and the circumference are the variables.
So, [tex]C \propto d[/tex]
Therefore the constant of proportionality is [tex]\pi[/tex]
