the Total weight of the container that kept figs is 1.6 kg.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, 80 figs are kept in a container. Each fig weighs 0.02 kg.
Since,
One fig is weighing = 0.02 kg
So,
80 figs will weigh = 0.02 * 80

what is 7/22 as a decimal rounded to the nearest tenth
Answer:
0.3
Step-by-step explanation:
To solve this, I asked, "If 7 divided by 21 is 3, then 7 divided by 22 would have little to no difference in the tenths place, right?" And that question is correct. Answering this question, the decimal place could not be greater than 5, because 7/22 is the formula for another, more accurate, albeit shorter version of pi, but backwards. 7/22 is 0.31, and 0.31's tenths place has a 1 in it, so this, according to the laws of rounding, rounds downward. Therefore, the correct answer would be 0.3.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,440 ft Determine the flag's width and length if the length is 340 ft greater than the width
The flag's width is ft. Its length is ft.
Answer:
width of the flag is 440 feet and the length is 780 feet
Step-by-step explanation:
Let's call the width of the flag "w". Then the length of the flag can be represented as "w + 340".
The perimeter of the flag is the sum of all four sides, so we can write the following equation:
2w + 2(w + 340) = 2,440
Expanding the second term on the left side and simplifying:
2w + 2w + 680 = 2,440
4w + 680 = 2,440
Subtracting 680 from both sides:
4w = 1,760
Dividing both sides by 4:
w = 440
So the width of the flag is 440 feet and the length is 780 feet (440 + 340).

The Marginal Revenue MR(29) 11513 dollars per unit.
The velocity is v(t) = 24t² - 96t - 120.
The velocity equals zero at t = 5.
The acceleration of the particle is a(t) = 48t - 96.
What is the velocity?Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.
Suppose a product's revenue function is given by R(q) = -7q² + 600q,
where R(q) is in dollars and q is units sold.
We have to determine a numeric value for the marginal revenue at 29 units
As per the question we have
R(q) = -7q² + 600q
Substitute the value of q = 29, and we get
R(29) = -7(29)² + 600(29)
R(29) = 11513
Thus, the Marginal Revenue MR(29) 11513 dollars per unit
Let s(t) = 8t³ - 48t² - 120t be the equation of motion for a particle.
To find the velocity, we need to differentiate the equation for the position of the particle, s(t).
v(t) = ds/dt = d/dt (8t³ - 48t² - 120t) = 24t² - 96t - 120
To find the t-values where the velocity is equal to zero, we need to set v(t) equal to zero and solve for t.
0 = 24t² - 96t - 120
This is a quadratic equation, and we can solve for t by factoring the GCF
(t - 5)(t + 1) = 0
(t - 5) = 0 and (t + 1) = 0
t = 5 and t = -1
So the velocity equals zero at t = 5
To find the acceleration, we need to differentiate the velocity function, v(t).
a(t) = dv/dt = d/dt (24t² - 96t - 120) = 48t - 96
So the acceleration of the particle is a(t) = 48t - 96.

The area of the walkway around the garden as the sum of two terms is, 2(w + l) = 2(8x + 21).
What is the area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Let's call the width of the garden w and the length of the garden l.
Then, the area of the garden is,
wl = 6(2.5x + 1.5).
The combined area of the garden and the walkway is 7.5(4x + 5).
We can write this as wl + 2(w + l), since the walkway goes around the perimeter of the garden.
Equating the two expressions for the combined area, we have:
wl + 2(w + l) = 7.5(4x + 5)
Substituting wl = 6(2.5x + 1.5), we get:
6(2.5x + 1.5) + 2(w + l) = 7.5(4x + 5)
Expanding both sides, we get:
15x + 9 + 2w + 2l = 30x + 37.5
Solving for w + l, we get:
w + l = 15x + 28.5 - 7.5 = 8x + 21
So the area of the walkway around the garden can be expressed as 2(w + l) = 2(8x + 21).

The length, in units, of the rectangle is 9 units.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Length = x
Width = x - 8
Area = 9 square units
Now,
The area of the rectangle = length x width

Solve for x.
x² - 8x - 9 = 0
x² - (9 - 1)x - 9 = 0
x² - 9x + x - 9 = 0
x(x - 9) + 1(x - 9) = 0
(x - 9) (x + 1) = 0

K * K > N, because if the square of K is greater than N, it is not possible to add K distinct odd integers to get N.
If you square an integer (multiply it by itself), the result will always be an even number. If K is an odd number, then K * K will be an odd number plus one, which makes it even.
For example, if K = 3, then K * K = 9, which is an even number. If we take the square root of 9, we get 3, which is K. This means that the square of K will always be greater than K itself.
Now, if we want to add K distinct odd integers to get N, then N must be greater than K * K. This is because the sum of K odd numbers will always be less than K * K, and we need N to be greater than this sum.
Therefore, if K * K > N, it means that it is not possible to add K distinct odd integers to get N, because N is smaller than K * K, and the sum of K odd numbers will be smaller than N.

Option(a) is the correct answer.

Here we can add 12 to both sides:
|X+6| <13 + 12
⇒|X+6| <25
⇒|X+6| < 25
We can separate it into two equations:
if x > -6, then |X+6| = x + 6
⇒ (x + 6) < 25
⇒x < 25 - 6
⇒ x < 19
if x < -6, then |X+6| = -(x + 6)

x is not an integer, and is instead an irrational number that lies between -1/6 and 1/9.
We can solve this problem using the law of sines. The law of sines states that for a triangle, the ratio of the side opposite an angle to the sine of that angle is equal for all three angles. Therefore, we can solve for x by setting up two equations, one for angle W and one for angle X.
For angle W, the equation is:
18x - 2 = sin-1(VX/WY)
For angle X, the equation is:
12x + 2 = sin-1(VW/YX)
Since we know the ratio of the sides of the triangle, we can solve for x by substituting these values into the equations.
For angle W, we get:
18x - 2 = sin-1(VX/WY)
18x - 2 = sin-1(2/2)
18x - 2 = 0
18x = 2
x = 1/9
For angle X, we get:
12x + 2 = sin-1(VW/YX)
12x + 2 = sin-1(2/2)
12x + 2 = 0
12x = -2
x = -1/6

You have 2 different savings accounts. For Account A, the simple interest earned after 6 months is $3.30. For Account B, the simple interest earned after 30 months is $37.50. If the interest rate is 3.3% for Account A and 2.5% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer
Principal amount in each account is $200 for Account A and $600 for Account B. Simple interest is most earned for Account B.
What is Simple Interest?Simple interest is defined as the interest obtained over the principal amount on a certain rate.
Simple interest is calculated by the formula,
SI = P × r × t,
where P is the principal amount, r is the interest rate and t is the time in years.
Account A :
t = 6 months = 0.5 year
S.I = $3.30
r = 3.3% = 0.033
Substituting in the formula,
3.30 = P × 0.033 × 0.5
P = 200
Principal amount in Account A is $200.
Simple interest earned in the first month = 200 × 0.033 × (1/12) = $0.55
Account B :
t = 30 months = 2.5 years
S.I = $37.50
r = 2.5% = 0.025
Substituting in the formula,
37.50 = P × 0.025 × 2.5
P = 600
Principal amount in Account B is $600.
Simple interest earned in the first month = 600 × 0.025 × (1/12) = $1.25
Account B earned more interest in the first month.
Hence Account B earned most interest in the first month with am amount of $1.25.

The entropy of X (number of defective chips) in bits is a measure of uncertainty about the value of X.
The entropy of a random variable represents the amount of uncertainty or randomness associated with the outcome of the variable. To calculate the entropy of a discrete random variable, we need to determine the probability distribution function and use the formula:
H(X) = -Σ P(X=x) log2(P(X=x))
In this case, the random variable X represents the number of defective chips in 5 randomly chosen chips from a box of 50, with 3 defective chips. The possible outcomes are 0, 1, 2, 3, and 4, with probabilities:
P(X=0) = (47/50)^5
P(X=1) = (5 * (3/50) * (47/50)^4)
P(X=2) = (10 * (3/50)^2 * (47/50)^3) / 2!
P(X=3) = (5 * (3/50)^3 * (47/50)^2) / 3!
P(X=4) = (3/50)^4 / 4!
By plugging in the probabilities into the entropy formula, we can find the entropy in bits.
