A game for $40 and the sales tax is two dollars what percent of the game price are you paying sales tax

Answer:

$96.93

Step-by-step explanation:

1. multipy the cost of the item (89.75) times the 8% tax.

    89.75 * 0.08 = 7.18 in tax

2. add the item cost plus tax

    89.75 + 7.18 = $96.93

Max will have to pay $ 96.93  in total for the DVD player.

An extra amount of money to be paid to the seller as tax on sales or on the receipt of sales is called sales tax.

According to the problem,

So, Max will have to pay $ { 89.75 + [tex](\frac{8}{100}) 89.75[/tex]}

                                   = $ 96.93

Answer:

The perimeter would also be multiplied by 6.

Step-by-step explanation:

The perimeter would also be multiplied by 6. Suppose the sides are 5 and 10. The perimeter would be the sum of the side lengths or 5 + 5 + 10 + 10 = 30.

Multiply each side length so 5*6 = 30 and 10*6 = 60. Find the perimeter by finding their sum, 30 + 30 + 60 + 60 = 180.

Divide the new perimeter by the old perimeter to find a scale factor.

180/30 = 6.

The new perimeter is exactly 6 times bigger since 6*30 = 180.

Answer:

The perimeter is multiplied by 6.

Step-by-step explanation:

For this case we must find the area of a scalene triangle (different sides) by means of Heron's formula:

[tex]S = \sqrt {p (p-a) (p-b) (p-c)}[/tex]

Where:

S: It's the area

p: It is the semiperimeter

a, b, c: They are the sides:

[tex]p = \frac {a + b + c} {2}\\p = \frac {25 + 13 + 17} {2}\\p = 27.5 \ units[/tex]

In the context of the problem, the zeros of the function represent the points in time when the roller coaster is at ground level. Specifically, the roller coaster goes underground at t = 5 seconds and comes back above ground at t = 8 seconds.

In the function f(t) = (t^2 − 13t + 40)(t^2 − 2t + 3), which models the height of the roller coaster above the ground, the zeros represent the points in time when the roller coaster is at ground level. In other words, when f(t) = 0, the height of the roller coaster is zero, implying it is at ground level. In your case, the zeros you found signify that the coaster is on the ground at the time instances t = 5 and t = 8 seconds since passing point A.

The values t = 5 and t = 8 seconds are the time instances when the roller coaster enters and exits the underground portion of the track respectively. It's crucial to comprehend the physical significance of mathematical solutions, particularly in real-world scenarios.

To calculate the volume of the triangular prism, first find the area of the right triangle that forms the base and then multiply it by the height of the prism.

The question involves finding the volume of a triangular prism whose base is a right triangle with sides measuring 7 inches, 24 inches, and 25 inches, where 25 inches is the hypotenuse. The height of the prism is given as 3 inches. To find the volume of the prism, we use the formula for the volume of a triangular prism, which is the area of the triangular base times the height of the prism.

First, we find the area of the triangular base using the formula for the area of a right triangle, which is (1/2) × base × height. For this triangle, the base and height are the perpendicular sides, which are 7 inches and 24 inches respectively. Thus, the area of the base triangle is (1/2) × 7 × 24 square inches.

Next, we multiply the area of the base by the height of the prism to get the volume. The height of the prism is 3 inches, so the volume will be the area of the base triangle times 3 inches.

For a system of 2 equations in 2 unknowns, there are 3 cases:

When slopes are different, the two lines intersect at one point, the solution.

When slopes are the same, the lines may be either parallel (different y-intercepts) or the same (same y-intercepts). If the lines are parallel, there are no points of intersection, hence no solutions. If the lines are the same line, they intersect at all points, so there are infinitely many solutions.

Answer:

m∠A = 9.1°

m∠B = 10.9°

c = 54.2

The answer is (d)

Step-by-step explanation:

∵ a = 25

∵ b = 30

∵ m∠C = 160°

∴ c² = a² + b² - 2 × ab × cos(C)

∴ c² = 25² + 30² - 2(25)(30) × cos(160) = 2934.5389

∴ c = 54.2

∵ a/sin(A) = b/sin(B) = c/sin(C)

∵ 25/sin(A) = 54.2/sin(160)

∴ sin(A) = (25 × sin(160)) ÷ 54.2 = 0.1577584

∴ m∠A = 9.1°

∵ 30/sin(B) = 54.2/sin(160)

∴ sin(B) = (30 × sin(160)) ÷ 54.2 = 0.18931

∴ m∠B = 10.9°

Answer:

The weight of the parcel is approximately 6 kilograms.

Step-by-step explanation:

The weight of the parcel is  12 lbs and 8 oz.

1 lb = 16 oz

So,  8 oz =  lb.

That means,  12 lbs and 8 oz = (12 + 0.5) lbs = 12.5 lbs

Now, 1 lb = 454 g

So,  12.5 lbs = (12.5 × 454) g = 5675 g

As,  1 kilogram = 1000 g

That means, 1 g = 0.001 kilogram

So,  5675 g  kilograms. (Rounded to the nearest whole kilogram)

Thus, the weight of the parcel is approximately 6 kilograms.

(c) it is not unusual for a radomly selected resident to oppose the casino and strongly oppose the​ casino.

Step-by-step explanation:

​(a) Find the probability that a randomly selected resident opposes the casino and strongly opposes the casino. ​

The probability that a radomly selected resident opposes the casino and strongly opposes the cassino is the product of the two probabilities, that a resident opposes the casino and that it strongly opposes the casino (once it is in the first group) as it is shown below.

Use this notation:

i) Determine the probability that a radomly selected resident opposes the casino, P(A)

Probability = number of favorable outcomes / number of possible outcomes

ii) Next, determine,the probability that a resident who opposes the casino strongly opposes it, P(B/A):

iii) You want the probability of both events, which is the joint probability or  intersection: P(A∩B).

So, you can use the definition of conditional probability:

iv) From which you can solve for P(A∩B)

(b) Find the probability that a randomly selected resident who opposes the casino does not strongly oppose the casino.

In this case, you just want the complement of the probability that a radomly selected resident who opposes the casino does strongly oppose the casino, which is 1 - P(B/A) = 1 - 8/10 = 1 - 0.8 = 0.2.

​(c) Would it be unusual for a randomly selected resident to oppose the casino and strongly oppose the​ casino?

You are being asked about the joint probability (PA∩B), which you found in the part (a) and it is 0.48.

That is almost 0.50 or half of the population, so you conclude it is not unusual for a radomly selected resident to oppose the casino and strongly oppose the​ casino.

f(x)=x^2+4x-5

Step-by-step explanation:

Quadratic functions are second-order polynomials. To solve a quadratic equation, set the function equal to zero, and use the quadratic formula. The corresponding polynomial function in this case is f(x) = x² + 5x - 1.

Quadratic functions are second-order polynomials. They are of the form f(x) = ax² + bx + c, where a, b, and c are constants. To solve a quadratic equation, set the function equal to zero, and use the quadratic formula: x = (-b ± √(b²-4ac))/(2a). The discriminant, b²-4ac, determines the number and nature of the solutions. If the discriminant is positive, there are two real solutions. If it is zero, there is one real solution (a perfect square). If it is negative, there are no real solutions, but there are two complex solutions.

In this case, the corresponding polynomial function is f(x) = x² + 5x - 1.

We are given a diameter of 10, the radius is half of the diameter, so for our problem r = 5.  Plug that in and evaluate

A = π(5²)

 A = 25π

or

A = 78.5398 if you multiply out pi

A full circle is 360 degrees.

The circle is separated into 8 parts, so each arc is 1/8 of a circle, which equals: 360/8 = 45 degrees.
