Answer: To find the sales tax rate as a percentage, we can use the following formula:

Sales Tax Rate = (Sales Tax / Cost Before Tax) * 100%

In this case, the sales tax is given as $20, and the cost before tax is $500. Plugging these values into the formula, we have:

Sales Tax Rate = ($20 / $500) * 100%

Simplifying the expression:

Sales Tax Rate = (0.04) * 100%

Sales Tax Rate = 4%

Therefore, the sales tax rate for the item is 4%.

The true statements about the graph of h(x) = ∛(x-4) are:

The domain of h(x) is the set of all real numbers.

For all points (x, h(x)), h(x) exists if and only if x - 4≥0

The graph of h(x) intercepts the x-axis at (4, 0).

The domain of h(x) is the set of all real numbers since there are no restrictions on the input variable x.

For all points (x, h(x)), h(x) exists if and only if x - 4 ≥ 0. This is because the cube root function is only defined for non-negative values, and the expression inside the cube root, x - 4, must be non-negative for h(x) to exist.

The graph of h(x) intercepts the x-axis at (4, 0) since plugging in x = 4 into the equation gives h(4) = ∛(4-4) = ∛0 = 0. This means that the point (4, 0) lies on the graph.

The numerical value of x in the dimensions of the rectangle is 9.

A rectangle is a 2-dimensional shape with parallel opposite sides equal to each other and four angles are right angles.

Area of a rectangle is expressed as;

A = length × width

From the diagram:

Wdith of the rectangle = x - 2

Length of the rectangle = x + 5

Area = 98 ft²

Since area of a rectangle =  length × width:

98 = ( x - 2 )( x + 5 )

Simplify

( x - 2 )( x + 5 ) = 98

Apply distributive property:

x² + 3x - 10 = 98

x² + 3x - 10 - 98 = 0

x² + 3x - 108 = 0

Factor using AC method:

( x - 9 )( x + 12 ) = 0

Hence:

x - 9 = 0 or x + 12 = 0

x = 9 or x = -12

Since, we are dealing with dimensions, we take the positive value.

Hence, the value of x is 9.

Angle C of the triangle measures 40°.

Side AC = 18.84

Side AB= 25.79

Given triangle,

∠A = 112°

∠B = 28°

BC = 37

Now,

Sum of all the interior angles of triangle is 180.

So,

∠A + ∠B +∠C = 180°

112° + 28° + ∠C = 180°

∠C = 40°

Now,

According to sine rule,

Ratio of side length to the sine of the opposite angle is equal.

Thus,

a/SinA = b/SinB = c/SinC

Let,

BC = a

AC = b

AB = c

So,

a/Sin112 = b/Sin28 = c/Sin40

37/0.921 = b/0.469 = C/0.642

Solving,

AB = c = 25.79

AC = b = 18.84

Answer:

Step-by-step explanation:

imagine copy and pasting your question.

The distance between the side AB are 314.2 ft.

In a triangle ABC AC = 200 ft, m ∠A = 72°, and m ∠B = 37°. we need to find the measure of the side AB,

So,

Using sine law.

Sin A / CB = Sin B / AC = Sin C / AB

Using the angle sum property of a triangle we find the value of angle C,

∠C = 180° - (∠A + ∠B)

∠C = 180° - (72° + 37°)

∠C = 180° - 109°

∠C = 71°

So,

Sin 37° / 200 = Sin 71° / AB

AB = 200 / Sin 37° × Sin 71°

AB = 314.2 ft

The probability that a customer ordered vanilla ice cream given they ordered a sundae is 0.75, or 75%.

To find the probability that a customer ordered vanilla ice cream given they ordered a sundae, we can use the concept of conditional probability.

The conditional probability of an event A given event B is denoted as P(A|B) and is calculated as the probability of both events A and B occurring divided by the probability of event B.

In this case, we want to find P(vanilla|sundae), which represents the probability of a customer ordering vanilla ice cream given that they ordered a sundae.

Using the given probabilities:

P(vanilla) = 0.3

P(sundae) = 0.2

P(vanilla and sundae) = 0.15

The probability of a customer ordering a sundae is the denominator for the conditional probability. Therefore, P(sundae) will be the denominator.

P(vanilla|sundae) = P(vanilla and sundae) / P(sundae)

Substituting the given values:

P(vanilla|sundae) = 0.15 / 0.2

Now we can simplify:

P(vanilla|sundae) = 0.15 / 0.2

= 0.75

Therefore, the probability that a customer ordered vanilla ice cream given they ordered a sundae is 0.75, or 75%.

It will take approximately 2.32 hours to fill 11 tanks.

First, we need to convert the capacity of the tanks from gallons to liters, as the rate at which we empty the bottle is given in liters. Since 1 gallon is equal to 3.8 liters, the capacity of each tank is 50 gallons * 3.8 liters/gallon = 190 liters.

Now, let's calculate the time it takes to fill one tank:

The bottle is emptied at a rate of 2 liters every 8 seconds. To find the time it takes to fill one tank, we divide the capacity of the tank (190 liters) by the rate at which we empty the bottle (2 liters/8 seconds):

Time for one tank = 190 liters / (2 liters/8 seconds) = 190 liters * (8 seconds/2 liters) = 760 seconds.

Next, we need to find the total time required to fill 11 tanks. Since each tank takes 760 seconds to fill, we multiply this by 11 to account for the 11 tanks:

Total time to fill 11 tanks = 760 seconds/tank * 11 tanks = 8,360 seconds.

Finally, we convert the total time from seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour, so:

Total time to fill 11 tanks = 8,360 seconds * (1 minute/60 seconds) * (1 hour/60 minutes) = 2.32 hours (rounded to two decimal places).

Therefore, it will take approximately 2.32 hours to fill 11 tanks.

Let's start by finding the values of a, b, and c using logarithmic properties:

Taking the logarithm of both sides of [tex]\large\sf\:3^a = 9^b\\[/tex], we get:

[tex]\large\sf\:\log_3(3^a) = \log_3(9^b)\\[/tex]

Applying the power rule of logarithms, we can bring down the exponents:

[tex]\large\sf\:a\log_3(3) = b\log_3(9)\\[/tex]

Since [tex]\large\sf\:\log_3(3) = 1[/tex] and [tex]\large\log_3(9) = 2\\[/tex], we simplify to:

[tex]\large\sf\:a = 2b\\[/tex] ---- (1)

Similarly, taking the logarithm of both sides of [tex]\sf\:9^b = 27^c\\[/tex], we get:

[tex]\large\sf\:b\log_3(9) = c\log_3(27)\\[/tex]

Using the values of [tex]\sf\:\log_3(9)\\[/tex] and [tex]\sf\:\log_3(27)\\[/tex] as before, we have:

Now, let's substitute the value of b from equation (1) into equation (2):

[tex]\large\sf\:2(2b) = 3c\\[/tex]

[tex]\large\sf\:4b = 3c\\[/tex]

Rearranging, we find:

[tex]\large\sf\:c = \frac{4b}{3}\\[/tex] ---- (3)

We now have expressions for a, b, and c in terms of b. Let's substitute these into the expression [tex]\large\sf\:\frac{a}{b} + \frac{b}{c} + \frac{c}{a}\\[/tex]:

[tex]\large\sf\:\frac{a}{b} + \frac{b}{c} + \frac{c}{a} = \frac{2b}{b} + \frac{b}{\frac{4b}{3}} + \frac{\frac{4b}{3}}{2b}\\[/tex]

Simplifying further, we get:

[tex]\large\sf\:\frac{2}{1} + \frac{3}{4} + \frac{2}{3}\\[/tex]

Finding the common denominator and combining the fractions, we have:

Using binomial probability formula, we can determine the number of defective batteries

In this case, n = 1,200 (the sample size) and p = 0.006 (the probability of finding a defective battery).

We want to find the probability of finding 5 or fewer defective batteries, which is equivalent to finding the cumulative probability up to 5.

Let's calculate this probability:

P(X ≤ 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

Answer:

$3827.00

Step-by-step explanation:

To calculate the total compound amount at the end of six years with an interest rate of 1.5% compounded annually, we can use the formula for compound interest:

A = P * (1 + r/n)^(n*t)

Where:

A = Total compound amount

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of times interest is compounded per year

t = Number of years

In this case:

P = $3500

r = 1.5% = 0.015 (as a decimal)

n = 1 (compounded annually)

t = 6 years

Substituting these values into the formula, we have:

A = 3500 * (1 + 0.015/1)^(1*6)

Calculating this expression, we get:

A ≈ 3500 * (1.015)^6 ≈ 3500 * 1.093717 ≈ 3827.00

Rounding the total compound amount to 2 decimal places, the final value is approximately $3827.00

Step-by-step explanation:

area of kite = (diagonal 1 × diagonal 2) / 2

Let the length of the shorter diagonal = x.

The length of the longer diagonal is 4x.

The area is the product of the diagonals divided by 2.

area = 4x × x / 2 = 4x²/2 = 2x²

The area is 72 m².

Therefore, 2x² must equal 72 m².

2x² = 72 m²

Divide both sides by 2.

x² = 36 m²

Take the square root of both sides.

x = 6 m

The short diagonal has length 6 m.

The long diagonal is 4x long.

4x = 4(6 m) = 24 m

Answer: 6 m, 24 m

Answer:

6 metres and 24 metres

Step-by-step explanation:

The kite will be composed of two smaller triangles and two larger triangles.

Let's call the shorter diagonal (across the kite) W.

So the longer diagonal (top to bottom of kite) will be 4W.

area = (L X W)/2

= (4W X W)/2

= 4W²/2

= 2W².

2W² = 72

W² = 36

W = 6 metres.

so the shorter diagonal is 6 metres.

the longer diagonal is 4 X 6 = 24 metres

To find the missing angle and side measures of ΔABC, we can use the properties of a triangle.

Given:

∠A = 50°

∠C = 90°

CB = 16

We can start by finding the measure of ∠B:

∠A + ∠B + ∠C = 180° (Sum of angles in a triangle)

50° + ∠B + 90° = 180°

∠B + 140° = 180°

∠B = 180° - 140°

∠B = 40°

Now, using Sine law

CB/ sin A = AB / sin C

16 / sin 50 = AB / sin 90

16 / 0.766044 = AB

AB = 12.25

Again 12.25 = AC/ sin B
