Step-by-step explanation:

it is super easy

Answer:

C) 5.25s^2

Step-by-step explanation:

1. Multiply 1.5s x 3.5s = 5.25.

2) Because 1.5 has one s, and 3.5 has another s, these 2 s combine (s+s)=s^2. Meaning there is 2 s in the equation. s^2 happens when you multiply two numbers that each have an s. Multiplication in this problem is brought by the use of parenthesizes surrounding these 2 numbers.

Answer:

81 adult tickets were sold that day

Step-by-step explanation:

We will need a system of equations to solve for the number of adult tickets sold.

First equation: For reference, revenue refers to price * quantity.  

(price of child tickets * quantity of child tickets) + (price of adult tickets * quantity of adult tickets) = total revenue.

Allowing C to represent the number of child tickets and A to represent the number of adult tickets, our first equation is:

5.20C + 8.60A = 956.60

Second Equation:  

Thus, our second equation is:

C + A = 131

Method to Solve:  We can solve for A using substitution.  Let's isolate C in the second equation and plug it in for C in the first equation:

Isolating C in second equation:

(C + A = 131) - A

C = -A + 131

Substituting -A + 131 for C in first equation:

5.20 (-A + 131) + 8.60A = 956.60

-5.20A + 681.20 + 8.60A = 956.60

3.40A + 681.20 = 956.60

3.40A = 275.40

A = 81

Optional Checking Step:

We can check that we've correctly found the correct number of adult tickets sold by first using the second equation in our system to solve for C:

C + 81 = 131

C = 50

Second, we want to plug in 81 for A and 50 for C in both equations in our system and check that we get 956.60 and 131 respectively:

Checking solutions for first equation:

5.20(50) + 8.60(81) = 956.60

260.00 + 696.60 = 956.60

956.60 = 956.60

Checking solutions for second equation:

50 + 81 = 131

131 = 131

The sum of first 10 terms is 72.

Concept: Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. It is also called Arithmetic Sequence.

Arithmetic Progression Formula

= an - a. nth term of an AP: an = a + (n - 1)d. Sum of n terms of an AP: Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the last term of the arithmetic progression.

Given:

Eighth term is 8.2

Common difference is 0.4

a(8) = 8.2

a + 7d = 8.2

Since d = 0.4

a + 7(0.4) =8.2

a = 5.4

Sum of 10 terms = n/2 (2a+(n-1)d)

= 5(2*5.4 + 9*0.4)

=5(10.8 +3.6)

Sum=72

Box B has the smaller range of masses, with a range of 49 grams, compared to Box A's range of 97,649 grams.

The question asks which of the boxes has the smaller range of masses and what is the value of this range in grams (g).
To find the range, we need to subtract the smallest value from the largest value in each box.
In Box A, the smallest value is 4 and the largest value is 97653. So, the range in Box A is 97653 - 4 = 97649 g.
In Box B, the smallest value is 2 and the largest value is 8762. However, we are given that key 35 represents a mass of 53 g and key 51 represents a mass of 51 g. So, the actual largest value in Box B is 51. Therefore, the range in Box B is 51 - 2 = 49 g.
Comparing the ranges, we can see that the range in Box B (49 g) is smaller than the range in Box A (97649 g).

Given parallelogram points are (4,3),(-4 3), and (2, -3).

Let's say A= (4,3) , B=(-4 3) ,C=(2, -3) and D=(x, y)

Parallelogram defined as opposite sides are equal and parallel to each other.

From the properties of parallelogram :

We can say diagonals bisect each other.

From this we can easily find 4th point of parallelogram by using mid point concept.

Mid point formula

 (X,Y)=\((\frac{x_{1} +x_{2}}{2},\frac{y_{1} +y_{2}}{2})\)

Find mid point between AC line

midpoint (X,Y)= \((\frac{4 +2}{2},\frac{3-3}{2})\)

                (X,Y)=\((\frac{6}{2},\frac{0}{2})\)

                 (X,Y)=(3,0)

Find mid point between BD Line

Mid point (X,Y)= \((\frac{-4 +x}{2},\frac{3+y}{2})\)

Mid point of AC and BD are equal to each other

(3,0)=\((\frac{-4 +x}{2},\frac{3+y}{2})\)

Equate x-coordinate and y-coordinate.

\(3=(\frac{-4 +x}{2})\)        and      \(0=(\frac{3+y}{2})\)

6=-4+x             and       0=3+y

The coordinates of the fourth point that would complete the parallelogram are (10, -3).

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

We know A, B, and C, where A = (4, 3), B = (-4, 3), and C = (2, -3).

To determine the fourth point, which represents D.

First, we need to find the vector representing side AB.

Subtracting the coordinates of point B from the coordinates of point A. So:

AB = A - B = (4, 3) - (-4, 3) = (8, 0)

Next, we need to find a point that is on the line that is parallel to AB and passes through point C.

The vector CD (where D is the point) is equal to AB. So:

CD = AB = (8, 0)

We know that C = (2, -3),

We can start by adding CD to C to get D:

D = C + CD = (2, -3) + (8, 0) = (10, -3)

Therefore, the coordinates of the fourth point are (10, -3).

Answer:The question is a little incorrect, the ice sheet thickness should be 2m and not 222m.

The required function formula is,

S(t) = 2 - 0.25 t

Step-by-step explanation:

Here, the initial thickness of the ice sheet = 2 meters,

After 3 weeks, the thickness of ice sheet = 1.25 meters

Total changes in the thickness in 3 weeks = 2 - 1.25 = 0.75 meters,

⇒ Total changes in the thickness in 1 weeks = 0.75/3 = 0.25 meters,

Since, the ice is melting with the constant rate.

⇒ The rate of ice decreasing = 0.25 meters per week.

⇒ Total changes in t weeks = 0.25 t meters

The new thickness of ice after t weeks = Initial thickness - Total changes in t weeks.

⇒ S(t) = 2 - 0.25 t

Which is the required function's formula.

The total cost of the loan with yearly compounding is $34,140, with quarterly compounding is $34,262.03, and with monthly compounding is $34,331.97.

To determine the total cost of the loan under different compounding frequencies, we can use the formula for compound interest: Total cost = Principal amount + Interest. Given: Principal amount (P) = $31,840, Annual interest rate (r) = 7.5% = 0.075. Yearly compounding: To calculate the total cost with yearly compounding, we can use the formula: Total cost = P * (1 + r)^n, Where n represents the number of years.

Using the given values, the total cost with yearly compounding is: Total cost = $31,840 * (1 + 0.075)^1 = $34,140. Quarterly compounding: To calculate the total cost with quarterly compounding, we need to adjust the interest rate and the compounding period: Annual interest rate (r) = 7.5% = 0.075. Number of compounding periods per year (n) = 4. The formula for quarterly compounding is: Total cost = P * (1 + r/n)^(n*t), Where t represents the number of years. Using the given values, the total cost with quarterly compounding is: Total cost = $31,840 * (1 + 0.075/4)^(4*1) = $34,262.03

Monthly compounding: To calculate the total cost with monthly compounding, we adjust the interest rate and the compounding period again: Annual interest rate (r) = 7.5% = 0.075, Number of compounding periods per year (n) = 12, The formula for monthly compounding is:

Total cost = P * (1 + r/n)^(n*t), Using the given values, the total cost with monthly compounding is: Total cost = $31,840 * (1 + 0.075/12)^(12*1) = $34,331.97. Therefore, the total cost of the loan with yearly compounding is $34,140, with quarterly compounding is $34,262.03, and with monthly compounding is $34,331.97.

The correlation coefficient that indicates the strongest relationship between two variables is a. -1.0.

The correlation coefficient is a numerical measure that quantifies the relationship between two variables. It ranges from -1 to +1, where -1 indicates a perfect negative correlation, +1 indicates a perfect positive correlation, and 0 indicates no correlation.

In this case, a correlation coefficient of -1.0 represents a perfect negative correlation, meaning that the two variables have a strong, linear relationship where as one variable increases, the other decreases in a perfectly predictable manner. This indicates a very strong and consistent inverse relationship between the variables.

In comparison, a correlation coefficient of 0.80 indicates a strong positive correlation, but it is not as strong as a perfect negative correlation of -1.0. A correlation coefficient of 0.1 suggests a weak positive correlation, while a correlation coefficient of -0.45 indicates a moderate negative correlation.

Therefore, out of the given options, the correlation coefficient of -1.0 represents the strongest relationship between two variables.
