Jessica fills a cube shaped tank that has an edge of 70 cm with water from a tap. Water flows into the tank at a rate of 7L per minute. How long will it take to fill the tank fully?
The volume of the tank is (70 cm)³ = 343,000 cm³.
Now,
1 mL = 1 cm³
1 L = 1000 mL
so we convert the given rate to
\(\dfrac{7\,\rm L}{1\,\rm min} \cdot \dfrac{1000\,\rm mL}{1\,\rm L} \cdot \dfrac{1\,\mathrm{cm}^3}{1\,\rm mL} = \dfrac{7000\,\mathrm{cm}^3}{1\,\rm min}\)
Then the time it will take to fill up the tank is
\(343,000\,\mathrm{cm}^3 \cdot \dfrac{1\,\rm min}{7000\,\mathrm{cm}^3} = \boxed{49\,\rm min}\)

The third, fifth and eighth terms of an AP are the first 3 consecutive terms of a GP. Given that the first term of the AP is 8, calculate the common difference
Answer:
Common Difference = 2.
Step-by-step explanation:
An AP can be written as a1, a1 + d, a1 + 2d, a1 + 3d, a1 + 4d, a1 + 5d, a1 + 6d , a1 + 7d.
where a1 = first term and d is the common difference.
Here first term = a1 = 8
3rd term = a1 + 2d = 8 + 2d
5th term = a1 + 4d = 8 + 4d
8th term = 8 + 7d
First 3 terms of a GP are a , ar and ar^2
So from the given information:
a = 8 + 2d
ar = 8 + 4d
ar^2= 8 + 7d
Dividing the second equation by the first we have
r = (8 + 4d)/(8 + 2d)
Dividing the third by the second:
r = (8 + 7d) / (8 + 4d)
Therefore, eliminating r we have:
(8 + 4d)/(8 + 2d) = (8 + 7d)/(8 + 4d)
(8 + 4d)^2 = (8 + 2d)(8 + 7d)
64 + 64d + 16d^2 = 64 + 72d^ + 14d^2
2d^2 - 8d = 0
2d(d^2 - 4) = 0
2d = 0 or d^2 = 4, so
d = 0, 2.
The common difference can't be zero so it must be 2.

calculate the coefficient of variation for a sample of cereal boxes with a mean weight of 340 grams and a standard deviation of 5.2 grams.? 0.15% A
1.53% B
15.29% C
0.65% D
The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.
In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.
CV = (Standard Deviation / Mean) * 100
CV = (5.2 / 340) * 100
CV ≈ 1.53%
Therefore, the correct answer is option B: 1.53%.

The elevation of Death Valley is -86 meters. Which equation shows how many meters below sea level Death Valley is located?
This equation shows that Death Valley is located 86 meters below sea level.
What is equation ?
An equation is a mathematical statement that shows the equality between two expressions. It typically contains variables, constants, and mathematical operations
The equation that shows how many meters below sea level Death Valley is located is:
Sea level elevation - Death Valley elevation = Sea level elevation - (-86 meters)
Simplifying this equation gives:
Sea level elevation + 86 meters = Sea level elevation - (-86 meters) + 86 meters
Therefore, the equation is: Sea level elevation + 86 meters = 0
This equation shows that Death Valley is located 86 meters below sea level.

A beg of corn can feed 100 chickens for 12 days . For how many days would the same bag feed 80 chickens
Answer:
9.6 days
Step-by-step explanation:
100 chickens, 12 days
find the days for 10 chickens: 1.2 days (to get 10 you have to divide 100 by ten, so divide 12 by ten too)
times by 8 to get the days for 80 chickens: 9.6 days
Answer: Let's assume that the bag of corn contains "C" units of corn. We know that this amount of corn can feed 100 chickens for 12 days.
To determine how long the same bag of corn would feed 80 chickens, we can use the following proportion:
(Corn units)/(chickens * days) = (Corn units)/(chickens * days)
We can set up two ratios, one for the original situation and one for the new situation, and then cross-multiply to solve for the unknown value:
C/100 * 12 = C/80 * d
where "d" is the number of days that the same bag of corn would feed 80 chickens.
Simplifying the equation, we get:
C/10 = C/80 * d
Multiplying both sides by 80, we get:
8C = Cd
Dividing both sides by "C", we get:
8 = d
Therefore, the same bag of corn would feed 80 chickens for 8 days.

find y(2) if dy/dx=8y and y(0)=10
To find y(2), we first need to solve the given differential equation: dy/dx = 8y.
1. Separate variables: divide both sides by y and multiply both sides by dx. This gives us (1/y) dy = 8 dx.
2. Integrate both sides: ∫(1/y) dy = ∫8 dx.
3. The antiderivative of (1/y) is ln|y|, and the antiderivative of 8 is 8x. So we have ln|y| = 8x + C, where C is the integration constant.
4. Solve for y: y = e^(8x + C) = e^(8x) * e^C. Since e^C is also a constant, we can replace it with another constant, say k: y = k * e^(8x).
5. Use the initial condition y(0) = 10 to find the value of k: 10 = k * e^(8 * 0), so k = 10.
6. Plug in the value of k to get the final solution: y = 10 * e^(8x).
Now we can find y(2) by plugging in x = 2: y(2) = 10 * e^(8 * 2) = 10 * e^16.

Whar wil be the cost of the thbase? A $4 millon B. $20 million C $25 million D. $29 million
The cost of the rebate will be $20 million. Therefore, option B is correct.
To calculate the cost of the rebate:
Given information:
- Current price of the minivan: $31,000
- Price after the rebate: $30,000
- Current sales: 25,000 vehicles
- Estimated sales after the rebate: 29,000 vehicles
- Profit margin per vehicle: $5,000
Increase in sales = Estimated sales after rebate - Current sales
= 29,000 vehicles - 25,000 vehicles
= 4,000 vehicles
Cost of the rebate = Increase in sales * Profit margin per vehicle
= 4,000 vehicles * $5,000 per vehicle
= $20,000,000

Cary sets up a checking account with an initial balance of $27,700, and the rent for her
apartment is deducted every month for a year. After a year the balance is $7900
(Assume no other transactions occur on the account)
Answer:
$1,650
Step-by-step explanation:
First, we need to find how much she paid the whole year. 27,700-x=7900. If we subtract 7900 from each side and add x to each side, we get 19,800=x. Therefore, she paid $19,800 in rent the whole year. Since there are 12 months in a year, and each month she paid the same, she paid $1,650 in rent each year, for 19800/12=1650

determine which point from the specified set satisfies the system of equations. y=3x−3 and y=−x 2
There are two points that satisfy the system of equations:
(0.79, 0.37)
(-3.79, -12.37)
The system of equations is:
y = 3x - 3
y = -x^2
To determine which point from a specified set satisfies the system of equations, we need to find the values of x and y that satisfy both equations simultaneously.
Substituting y = 3x - 3 into the second equation, we get:
3x - 3 = -x^2
Rearranging this equation, we get:
x^2 + 3x - 3 = 0
Using the quadratic formula, we can solve for x:
x = (-3 ± sqrt(3^2 - 41(-3))) / (2*1) = (-3 ± sqrt(21)) / 2
Therefore, there are two possible values of x that satisfy the system of equations:
x = (-3 + sqrt(21)) / 2 ≈ 0.79
x = (-3 - sqrt(21)) / 2 ≈ -3.79
To find the corresponding values of y, we can substitute these values of x into either equation. For example, if we use y = 3x - 3, we get:
y ≈ 0.37 (when x ≈ 0.79)
y ≈ -12.37 (when x ≈ -3.79)
Therefore, there are two points that satisfy the system of equations:

False. The metric system is a decimalized system of measurement, but it is not used exclusively in the United States.
In fact, the United States primarily uses the U.S. customary system, while the metric system is widely used in most other countries around the world.
Most nations throughout the world use the metric system, a decimal-based measurement system that is universally recognised. It offers a standardised method for gauging temperature, length, mass, and other physical attributes. The metre (for length), kilogramme (for mass), second (for time), ampere (for electric current), kelvin (for temperature), mole (for amount of material), and candela (for luminous intensity) are the basic units of the metric system. Because the metric system is based on powers of 10, converting between units is simple.
