Answer: 257
257 in delta math
Step-by-step explanation:
After 7 years, Riley would $441.5 more have in her account than Ryan.
What is compound interest?Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Given that Riley invested $5,100 in an account paying an interest rate of \(7\tfrac{3}{4}\)% compounded quarterly. Ryan invested $5,100 in an account paying an interest rate of \(7\tfrac{1}{4}\) % compounded daily, we need to find that after 7 years how much more money would Riley have in her account than Ryan,
\(A = P(1+r/n)^{nt\)
Where A = amount
P = principal
r = rate
n = number of times the amount is compounded and t = time
Riley = compounded quarterly,
\(A = P (1 + r / 4)^{4t\)
\(A = 5100(1+0.019375)^{4(7)}\\\\A = 5100(1.019375)^{28}\\\\\\\)
\(A = 8728.13\)
Therefore, in 7 years Riley has $8728.13.
Ryan = compounded daily,
\(A = P (1 + r / 365)^{365t\)
\(A = 5100(1 + 0.00019)^{356(7)}\\\\A = 5100(1.00019)^{2555}\\\\A = 8286.64\)
Therefore, in 7 years Ryan has $8286.64.
Riley will have $441.5 more.
Hence after 7 years, Riley would $441.5 more have in her account than Ryan.

Suppose a particle moves back and forth along a straight line with velocity v(t), measured in feet per second, and acceleration a(t). a) What is the meaning of 120 â« v(t) dt? 60 b) What is the meaning of 120 â« |v(t)| dt? 60 c) What is the meaning of 120 â« a(t) dt? 60
In this case, the displacement of the particle at time t is given by ∫ v(t) dt, and the displacement after 120 seconds is given by ∫_0^120 v(t) dt.
The integral of |v(t)| over the time interval [0, 120] gives the total distance traveled by the particle during that time.
Specifically, the value of the integral gives us the difference between the velocity of the particle at time t=120 and its velocity at time t=0.
a) The integral 120 ∫ v(t) dt represents the displacement of the particle from its starting point after 120 seconds, assuming that its initial displacement is zero. This can be seen by the fundamental theorem of calculus, which states that if F(x) is an antiderivative of f(x), then ∫ f(x) dx = F(b) - F(a), where a and b are the limits of integration. In this case, the displacement of the particle at time t is given by ∫ v(t) dt, and the displacement after 120 seconds is given by ∫_0^120 v(t) dt.
b) The integral 120 ∫ |v(t)| dt represents the distance that the particle travels in 120 seconds. This is because |v(t)| represents the magnitude of the velocity, or speed, of the particle at time t, regardless of its direction. Thus, the integral of |v(t)| over the time interval [0, 120] gives the total distance traveled by the particle during that time.
c) The integral 120 ∫ a(t) dt represents the change in velocity of the particle over the time interval [0, 120]. This can be seen by the fundamental theorem of calculus, which tells us that if f(x) is the derivative of g(x), then ∫ f(x) dx = g(x) + C, where C is a constant of integration. In this case, a(t) is the derivative of v(t), so the integral of a(t) over the time interval [0, 120] gives us the change in velocity of the particle during that time. Specifically, the value of the integral gives us the difference between the velocity of the particle at time t=120 and its velocity at time t=0.

Drag each value to the correct location on the circle. Not all values will be used.
Circle F has radius of 4 inches with a central angle of 120°. Determine the measure of the central angle in radians, the arc length of RS
, and the area of sector RFS.
The area of sector RFS is approximately 8π square inches, and the measure of the central angle in radians is approximately 2π/3 radians.
What is the central angle?
A central angle is an angle with endpoints and located on a circle's circumference and a vertex located at the circle's center. A central angle in a circle determines an arc.
To determine the measure of the central angle in radians, we can use the formula:
radians = degrees * (π / 180)
So, for the central angle of 120°:
radians = 120 * (π / 180) = 2 * π / 3
The measure of the central angle in radians is approximately 2 * π / 3 radians.
To find the arc length of RS, we can use the formula:
arc length = (central angle / 360) * circumference
The circumference of the circle is given by 2 * π * r, where r is the radius:
circumference = 2 * π * 4 = 8 * π
So the arc length is:
arc length = (120 / 360) * (8 * π) = 4 * π / 3
The arc length of RS is approximately 4 * π / 3 inches.
To find the area of sector RFS, we can use the formula:
area = (central angle / 360) * π * r²
So the area of sector RFS is:
area = (120 / 360) * π * (4)² = 8 * π
Therefore, The area of sector RFS is approximately 8π square inches, and the measure of the central angle in radians is approximately 2π/3 radians.

Area of the circular sidewalk = 405 m²
Step-by-step explanation:
Radius of the circular flower bed = 20 m
Area of the circular bed = πr²
Here r = radius of the circle
Area of the circular bed = π(20)²
= 400π square meter
Radius of the larger circle = Radius of the flower bed + width of the sidewalk
= 20 + 3
= 23 m
Area of the larger circle = π(23)²
= 529π m²
Area of the circular sidewalk = Area of the larger circle - Area of the flower bed
= 529π - 400π
= 129π
= 129(3.14)
= 405.06 square meters

How many grams are in 3.29 X 10²5 molecules of water (H₂O)?
Water molecules with a mass of 3.34 * (10 )23 weigh 9.911 grams.
What is the mass in grams of 3.34 x 1023 molecules of H2O?Firstly, you wish to transform the quantity of water molecules you have into the quantity of moles.
Undoubtedly, you are aware
Number of Particles = Mole Ratio x Avogadro's Constant
Avogadro's constant is equal to 3.34 * (10) 23 / 6.02 * (10) 23 when the number of moles is equal to the number of particles.
=0.55
so 0.55 moles
Consequently, mass/molar mass = number of moles.
Since we must determine the mass, we can use the formula Mass = Number of Moles x Molar Mass.
H 2 O's molar mass is calculated as H - 2(1.01) = 2.02 O- 16 18.02
Consequently, 18.02 g/mol is the molar mass.
We now possess the necessary values to determine the mass because of this.
Mass = 0.55 × 18.02
Mass = 9.911
As a result, the 3.34 mass
There are 9.911 grams in 3.34 * (10 )23 water molecules.

Answer:
x=-4
Step-by-step explanation:
-2x+3=11
subtract 3 from both
-2x=8
divide by -2
x=-4
The solution to the equation is x = -4.
To solve the equation -2x + 3 = 11 for 'x,' follow these steps:
Step 1: Subtract 3 from both sides of the equation to isolate the term with 'x':
-2x + 3 - 3 = 11 - 3
-2x = 8
Step 2: Divide both sides by -2 to solve for 'x':
(-2x) / (-2) = 8 / (-2)
x = -4
The solution to the equation is x = -4. To verify, substitute 'x' with -4 in the original equation:
-2(-4) + 3 = 8 + 3
8 + 3 = 11
Since both sides are equal, the value of x = -4 is correct. Therefore, the solution to the equation is x = -4.

Mr Wong invested 5 000 units of shares valued at $1.60 per unit in Cemerlang Company. He received dividend of $118 twice and a bonus of 3.3% during the time he was holding the shares. After selling all the units of shares, he received $9 100. Calculate the return on investment for Mr Wong.
Answer:
The total amount of money Mr. Wong received from dividends is $118 * 2 = $236.
The total value of Mr. Wong's shares before the bonus was 5,000 * $1.60 = $8,000.
The bonus he received was 3.3% of $8,000 = $264.
So, the total amount of money Mr. Wong received from the investment was $236 + $264 + $9,100 = $9,600.
The return on investment for Mr. Wong is the total amount of money he received from the investment divided by the amount of money he initially invested, expressed as a percentage.
So, the return on investment is ($9,600 / $8,000) * 100% = 120%.
Therefore, the return on investment for Mr. Wong is 120%.

What is chi-square test of hypothesis? Explain more indetail?In the chi-square test of hypothesis, the null hypothesis states that the variables under consideration are independent. That is, there is no relationship between the two variables being studied.
The chi-square test is a statistical method used to determine if two categorical variables are associated or independent. Categorical variables are those that take on values that are categories or labels.
For example, gender (male or female) or educational level (high school, college, graduate school) are categorical variables.
The chi-square test determines the expected frequency of each category based on the null hypothesis, which assumes independence between the two variables.
The observed frequency is then compared to the expected frequency, and if the difference is significant enough, it suggests that the null hypothesis should be rejected, and the two variables are considered to be associated or dependent.
Therefore, in summary, the null hypothesis in the chi-square test of hypothesis states that the two categorical variables under consideration are independent of each other, meaning that there is no relationship or association between them.

abed says he has written a system of two linear equations that has an infinite number of solutions. one of the equations of the system is y
Abed is correct. It is possible to have a system of two linear equations that has an infinite number of solutions. One of the equations in the system is y.
In a system of linear equations, each equation represents a line on a graph. When we solve the system, we are looking for the point(s) of intersection between the lines. There are three possible scenarios for the solution of a system of linear equations: no solution (the lines are parallel and never intersect), a unique solution (the lines intersect at a single point), or infinite solutions (the lines overlap and coincide with each other).
If Abed has written a system with one of the equations being y, it means that the equation represents a horizontal line parallel to the x-axis. Let's denote this equation as y = k, where k is a constant. Since the equation is horizontal, it does not depend on x and remains the same for all values of x. This means that every point on this line satisfies the equation y = k.
Now, let's consider the second equation in the system. Since the system has an infinite number of solutions, the second equation must coincide with the horizontal line y = k. In other words, the second equation can be any equation of the form y = k', where k' is also a constant.
Since both equations are equivalent and represent the same line, every point on the line satisfies the system of equations. Therefore, the system has an infinite number of solutions.

There is a 0.6543 percent chance that no leak will ever appear in any of the homes.
What do you mean by random variable?
A random variable is a numerical representation of how a statistical experiment turned out. Discrete random variables can only take on a finite number of values or an infinite series of values, but continuous random variables can take on any value within a range on the real number line.
Let X represent the quantity of leak-prone homes in a city.
There is a 0.02 percent chance that a house in an urban location may experience a leak.
A sample of n = 21 homes is chosen at random.
Every home has a distinct chance of developing a leak.
As a result, the random variable X follows a binomial distribution with the parameters p = 0.02 and n = 21.
The likelihood that none of the homes will have a leak should be calculated as follows: The likelihood that none of the homes will experience a leak is therefore 0.6543.

Line l has a slope of m and contains points in quadrants I, II, and IV, but no points from quadrant III. Which of the following must be true about the value of m?
a) m < 0
b) m > 0
c) m = 0
d) slope m is undefined
The correct answer is (a) m < 0.Since line l contains points in quadrants I, II, and IV, but not in quadrant III, we can deduce the following.
Quadrant I: In this quadrant, both x and y coordinates are positive. For a line in quadrant I, the slope (m) must be positive. Quadrant II: In this quadrant, x coordinates are negative, and y coordinates are positive. For a line in quadrant II, the slope (m) must be positive. Quadrant IV: In this quadrant, x coordinates are positive, and y coordinates are negative. For a line in quadrant IV, the slope (m) must be negative.
Based on the observations in all the relevant quadrants, we can conclude that the slope (m) must be both positive and negative, indicating that it can take on both positive and negative values. Therefore, the correct answer is (a) m < 0.
