Answer: The total amount paid for shoes = $63.75

Step-by-step explanation:

The original price of the shoes = $ 80

Sale Discount = 25 %

So, the discount offered = 25 % of 80 = 20

So, the Discounted Price  = Marked price - discount

= $ 80 -$ 20 = $ 60

Now, we need to calculate the sale tax of 6.25 % on $ 60.

Also, we know that  Sales Tax = Sales Tax rate x Sale Price

= $ 60 x 0.0625  = $ 3.75

Total Cost = Sale Price + Sales Tax

=  $ 60 + $ 3.75  = $63.75

Hence, the total amount paid for shoes = $63.75 included sales tax

We can draw the conclusion that Sadio and Amir's methods for solving the equation are both valid.

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation.

As in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, and others.

Equation: A declaration that two expressions with variables or integers are equal.

In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

So, as we have the equation:

12x + 3 = 3(5x + 9)

Now, as we can see, Sadio took out 3 as common from LHS and RHS and solved the equation.

Which gave her the value of x as -8.

Amir, on the other hand, did not take out anything as common and directly multiply 3 with other terms in the brackets to solve the equation.

He also got -8 as the value of x.

Hence, we can conclude that yes both the ways of solving the equation is correct which is done by Sadio and Amir.

Therefore, we can draw the conclusion that Sadio and Amir's methods for solving the equation are both valid.

The percent increase of the population in the past 10 years is 12.5%.

Percent​ increase is simply the amount of increase from the initial value to the new value in terms of 100 parts of the initial value.

It is expressed as;

C = ((x₂ - x₁) / x₁)100%

Where x₁ is initial value and x₂ is new value

Given that;

Plug in the given values into the above equation and simplify.

C = ((x₂ - x₁) / x₁) × 100%

C = (( 9000 - 8000 ) / 8000) × 100%

C = ( 1000 / 8000) × 100%

C = 0.125 × 100%

Answer:

A van can carry 18 students; a bus can carry 41 students.

Step-by-step explanation:

Let v = capacity of van.

Let b = capacity of bus.

School A:

3v + 12b = 546

School B:

13v + 6b = 480

Our system of equation is:

3v + 12b = 546

13v + 6b = 480

      3v + 12b = 546

+  -26v - 12b = -960

-----------------------------

    -23v         = -414

v = 18

3v + 12b = 546

3(18) + 12b = 546

54 + 12b = 546

12b = 492

b = 41

Answer: A van can carry 18 students; a bus can carry 41 students.

As a rule of thumb, altitude corrections of less than 100 feet for determining the pressure at a given altitude should be corrected using the standard pressure-altitude correction tables.

These tables provide the correction factor for the difference between the actual and standard atmospheric pressure at a given altitude. The correction factor can then be applied to the standard pressure value to obtain the actual pressure value at that altitude. Note that the standard atmospheric pressure is defined as 29.92 inches of mercury (in Hg) at sea level. The pressure decreases with increasing altitude in the lower atmosphere. The pressure-altitude correction tables provide a convenient and accurate way of determining the atmospheric pressure at different altitudes.

If Zach moved the existing sand from the old terrarium into the new terrarium , then the sand in the new terrarium will be  5cm deep .

The dimensions of the old terrarium is = 20 by 50   cm  ;

The dimensions of the new terrarium is = 25 by 64 cm ;

So , amount of sand that Zach has is =  Volume of sand in the old terrarium, that is ( Area of base of the old terrarium) × (height of sand) ;

Volume of Sand = 20 × 50 × 8 = 8000 cm³  ;

When Zach moves the sand to the new terrarium, volume of sand will be same, so we can write the equation ;

⇒ 20 × 50 × 8 = 25 × 64 × h  ;

where h is = height of sand in new terrarium.

Now solving for h, we get ;

⇒ h = (20 × 50 × 8 cm)/(25 × 64 )

The man can wear 15 different outfit combinations by mixing and matching his six different sport shirts and four different pairs of slacks.

Combination is a way of counting the number of different groups of items that can be selected from a larger set without regard to the order in which they are selected.

In this case, the man has six different sport shirts and four different pairs of slacks, and he wants to know how many different outfit combinations he can wear. We can use the formula for combinations to calculate the number of possibilities.

The formula for combinations is:

ⁿCₓ = n! / (x! * (n - x)!)

Where n is the total number of items, x is the number of items being selected, and the exclamation mark (!) represents the factorial of a number (i.e., the product of all positive integers up to that number).

Using this formula, we can calculate the number of different combinations the man can wear as follows:

Number of sport shirts (n) = 6

Number of slacks (x) = 4

Number of combinations = ⁶C₄ = 6! / (4! * (6 - 4)!)

= (6 * 5 * 4 * 3 * 2 * 1) / [(4 * 3 * 2 * 1) * (2 * 1)]

Answer:

Step-by-step explanation:

Given the volume of a cylinder, V = πr^2h, where r is the radius, h is the height, and π is Pi, we can find the radius by rearranging the equation and solving for r.

V = πr^2h, so r^2 = V / (πh)

Taking the square root of both sides, we have:

r = √(V / (πh))

Substituting the given values:

r = √(950 / (π * 10))

Since Pi is approximately equal to 3.14, we can calculate the approximate value of r:

r = √(950 / (3.14 * 10))

r ≈ 7.46

Therefore, the radius of the cylinder with a volume of 950 cubic inches and a height of 10 inches is approximately 7.46 inches.

We need  9 sophomore girls to make sex and class independent when a student is selected at random.

No. of freshman boys     (fb) = 4

No. of freshman girls      (fg) = 6

No. of sophomore boys (sb) = 6

Let, the no. of sophomore girls = sg

The total number of students in the class T = fb + fg + sb +sg

                                                                     T = 4+6+6+sg

                                                                     T = 16 + sg

The probability of selecting a girl is  P(G) = (fg + sg) / T

                                                                    = (6+sg)/(16+sg)

The probability of selecting a sophomore is  P(S) = (sb + sg)/T

                                                                                  = (6+sg)/(16+sg)

As the events are independent, the probability of selecting a sophomore girl is                       P(sg) = P(G)*P(S)

                       sg/(16+sg) = (6+sg)*(6+sg)/(16+sg)(16+sg)

                       sg(16+sg)  = (6+sg)(6+sg)

The probability that one card is a spade and the other is a king when two cards are drawn at random from a deck of 52 cards is 0.0196.

To calculate the probability that one card is a spade and the other is a king when two cards are drawn at random from a deck of 52 cards, we need to first determine the total number of possible outcomes, which is the number of ways to select two cards from a deck of 52. This can be calculated using the formula for combinations, which is:

nCr = n! / r!(n-r)!

where n is the total number of objects (52 cards in this case), r is the number of objects to be selected (2 cards), and ! denotes the factorial operation.

So, the total number of possible outcomes is:

52C2 = 52! / 2!(52-2)! = 1326

Next, we need to determine the number of favorable outcomes, which is the number of ways to select one spade and one king from the deck. Since there are 13 spades and 4 kings in a deck, there are 13 x 4 = 52 ways to select one spade and one king.

However, we need to divide this number by 2 to avoid double counting the two possible orders (king-spade or spade-king), which gives us 26 favorable outcomes.

P = favorable outcomes / total outcomes = 26 / 1326 = 0.0196 or about 1.96%

So, there is a very low probability of selecting one spade and one king when two cards are drawn at random from a deck of 52 cards.

The value of csc(3π/2) is -1.

What is a trigonometric function?

Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.

Numerous trigonometric identities and formulas indicate the relationship between the functions and aid in determining the triangle's angles.

The given trigonometry function is csc(3π/2)

Assume that y = csc(3π/2)

Break the angle:

y = csc(π + π/2)

Applying the formula csc(π + θ) = -csc θ:

y = - csc(π/2)

y = -1 [since csc(π/2) = 1]
