Mercury metal is poured into a graduated cylinder that holds exactly 22 ml. The mercury used to fill the cylinder weighs 308 g. From this information, calculate the density of mercury.
Answers
The density of mercury will be equal to 14 g/cm³.
It is given that the graduated cylinder holds exactly 22 ml and mercury used to fill the cylinder weighs 308 g.
We have to find out the density of the mercury.
What is the formula for density ?
The formula for density will be Density (D) = [tex]\frac{M}{V}[/tex] , where M is mass / weight of the object and V is the volume of the object.
As per the question ;
Graduated cylinder holds 22ml.
∵ 1 ml = 1 cc or cm³
So ,
The volume of graduated cylinder = 22 cm³
The weight of mercury = 308g
We know that ;
Density of mercury = Weight / Volume
⇒ Density of mercury = [tex]\frac{308}{22}[/tex]
⇒ Density of mercury = 14 g/cm³
Thus , the density of mercury will be equal to 14 g/cm³.

Because the population size may change over time, you also decide to look at rates,which for drug overdose are generally expressed as deaths/100,000 residents.The statepopulation for 2015 was estimated at 11,620,000.Calculate the rate of drug overdosedeaths
Answers
This question is incomplete, the complete question is;
As the junior public health epidemiologist in a large state in the Midwest Rust Belt, you have been asked by your supervisor to assist her in updating the statistics on opioid deaths. She is also asking for your help in writing a brief report describing the current situation for the annual report on drug abuse.
- In 2015, there were 3050 drug-related deaths, of which 2950 involved opioids, What percent of the deaths were due to opioids? Express your answer in the following format: XX.XX% (e.g., 54.81%).
- Because the population size may change over time, you also decide to look at rates, which for drug overdose are generally expressed as deaths/100,000 residents. The state population for 2015 was estimated at 11,620,000.Calculate the rate of drug overdose deaths.
Answer:
the rate of drug overdosedeaths is 27 per 100,000 residents
Step-by-step explanation:
Given that;
3050 drug-related deaths in 2015,
Deaths due to opioids in 2015 is 2950
percentage = (2950 / 3050) × 100 = 96.72%
therefore
percentage of the deaths that were due to opioids in 2015 is 96.72%
-
we know that
State population for 2015 = 11,620,000
Number of drug-related deaths in 2015 = 3050
Death rate is number of deaths recorded divided by the number of population, and then multiplied by 100,000 as in the question
so
Rate of drug overdose = (3050 / 11620000) × 100,000
=26.25 ≈ 27 per 100,000 residents { since of person can't be decimal)
therefore
the rate of drug overdosedeaths is 27 per 100,000 residents

Given that:
Fair dice is rolled once;
Winning = $4, if output is 6
If otherwise ; winning = - $1
M = amount of money won :
Distribution of M:
The amount of money won (M) is either :

Distribution of M:
Possible outcome : {1, 2, 3, 4, 5, 6}
P(winning $4) = P(rolling a 6)
Probability = number of required / number of total possible outcomes

Find an equation of a parabola that has curvature 6 at the origin. (Assume the parabola has its vertex at the origin, and opens upward.)
Answers
Answer:
The equation of a parabola that has a curvature 6 at the origin is [tex]f(x) = 3\cdot x^{2}[/tex].
Step-by-step explanation:
All parabolas are represented by second-order polynomials, whose standard form is:
[tex]f(x) = a\cdot x^{2}+b\cdot x + c[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficient of the parabola, dimensionless.
From Vectorial Calculus we know that curvature ([tex]K[/tex]), dimensionless, is defined by the following expression:
[tex]K = \frac{\left|\frac{d^{2}y}{dx^{2}} \right|}{\left[1+\left(\frac{dy}{dx} \right)^{2}\right]^{\frac{3}{2} }}[/tex] (Eq. 2)
Where [tex]\frac{dy}{dx}[/tex] and [tex]\frac{d^{2}y}{dx^{2}}[/tex] are the first and second derivatives of the function, respectively. Each expression is described below:
[tex]\frac{dy}{dx} = 2\cdot a\cdot x + b[/tex]
[tex]\frac{d^{2}y}{dx^{2}} = 2\cdot a[/tex]
If we know that [tex]a > 0[/tex], [tex]b = c = 0[/tex], [tex]x = 0[/tex] and [tex]K = 6[/tex], then the equation of curvature and polynomial are, respectively:
[tex]\frac{2\cdot a}{1^{\frac{3}{2} }} = 6[/tex]
[tex]a = 3[/tex]
The equation of a parabola that has a curvature 6 at the origin is [tex]f(x) = 3\cdot x^{2}[/tex].
An equation of a parabola that has curvature 6 at the origin is [tex]\rm f(x) = 3x^2[/tex].
We have to determine
An equation of a parabola that has curvature 6 at the origin.
What is the equation of a parabola that has a curvature at the origin?The equation of a parabola that has a curvature a at the origin is;
[tex]\rm f(x) = ax^2[/tex]
The value of a is given by k(0) = 8;
[tex]\rm k(0) = 2a\\\\6 = 2a\\\\a = \dfrac{6}{2}\\\\a=3[/tex]
Therefore,
The equation of a parabola that has a curvature a at the origin is;
[tex]\rm f(x) = ax^2[/tex]
[tex]\rm f(x) = 3x^2[/tex]
Hence, an equation of a parabola that has curvature 6 at the origin is [tex]\rm f(x) = 3x^2[/tex].

a) Write an equation to find the cost (c) to make a bracelet with b beads.
b) one of shawn's popular bracelets, the Charmer, includes 15 stone beads. Another bracelet, the sparkler, uses 20 beads. how much does it cost to make each bracelet?
I have no idea how to do this!
Answers
B). $10.70
The equation to find the cost (c) is C= 0.30b + 0.10.
The cost to make each bracelet is $10.70.
We have,
Shawn buy beads for $0.30 each.
The wire used to make each bracelet costs $0.10.
If C is the cost then the equation for the cost is
C = 0.30b + 0.10
where b is number of beads.
Now, Number of beads = 15 then cost is
C = 0.30(15) + 0.10 = $4.6
and, if number of beads is 20 then the cost is
C = 0.30(20)+ 0.10 = 6.1
Then, the total cost is = 4.6 + 6.1 = $10.7

3. Aimee bought 9.8 meters of Geena satin cloth. One-fifth of the cloth was damaged by rats and the rest was
used to make 7 similar blouses.
A. How much cloth did she use for each blouse?
B. If she sold each blouse for P 178.25, how much money would she receive in all?
Answers
Answer:
a, 1.12m
b, P 1257.75
Step-by-step explanation:
A,
9.8m × 4/5 = 7.84m
7.84m ÷ 7 = 1.12m
B,
7 × 178.25 = P1247.75
We are required to find how much cloth she used for each blouse
cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75
Total quantity of geena satin bought = 9.8 meters
Quantity damaged by rat = 1/5 of 9.8 meters
= 0.2 × 9.8
= 1.96 meters
Total cloth used for 7 blouse = Total quantity of geena satin bought - Quantity damaged by rat
= 9.8 meters - 1.96 meters
= 7.84 meters
Cloth used for each blouse = Total cloth used for 7 blouse / 7
= 7.84 / 7
= 1.12 meters
Cost of each blouse = P 178.25
Total cost of 7 blouses = P 178.25 × 7
= P 1247.75
Therefore, cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75

Answers
Answer:
There are 50 students in the sixth grade.
Step-by-step explanation:
Given that 88% of students have pets which means that only 12% do not have pets. It says that only 6 students do not have pets so we can assume that 12% is equals to 6 students. We have to form an expression for the number of students.
