Before Tax Price: $40.00

Sale Tax: 5.00% or $2.00

After Tax Price: $42.00

Step-by-step explanation:

Answer:

42 dollars

Step-by-step explanation:

When doing tax problems, we need to memorize the formula of:

price + tax • price = price with sales tax.

This formula works because you have the initial percentage of the cost, with the added tax, which gives the extra value--then added together it gives the sales cost price.

So let's plug our numbers in

40 + (0.05 or 5%) • 40 = price with sales tax

40 + 2 = price with sales tax

42 = price with sales tax

In response to the query, we have that The Pythagorean identity for theta = 30° is therefore confirmed since sin(30°) + cos(30°) = 1.

The fundamental Euclidean geometry relationship between the three sides of a right triangle is the Pythagorean Theorem, sometimes referred to as the Pythagorean Theorem. This rule states that the areas of squares with the other two sides added together equal the area of the square with the hypotenuse side. According to the Pythagorean Theorem, the square that spans the hypotenuse (the side that is opposite the right angle) of a right triangle equals the sum of the squares that span its sides. It may also be expressed using the standard algebraic notation, a2 + b2 = c2.

This trigonometric identity is valid for all theta values. Because it is connected to the geometry-related Pythagorean theorem, it is known as the Pythagorean identity.

According to Pythagorean theory,

[tex]Cos(theta)^2 + Sin(theta^)2 = 1[/tex]

So, you can easily include that value into the equation and simplify it if you need to assess sin(theta) + cos(theta) for a certain value of theta:

[tex]Cos(theta)2 + Sin(theta)2 = 1\\Sin(2) + Cos(30)\\If theta = 30, then 2(30) = 1.\\(1/2)\\c^2 + (√3/2)\\c^2 = 1 \s1/4 + 3/4 = 1 \s1 = 1[/tex]

The Pythagorean identity for theta = 30° is therefore confirmed since sin(30°) + cos(30°) = 1.

The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

Given that the circumference is 132ft and π is 22/7, we can write:

132 = (22/7)d

To solve for d, we can multiply both sides by 7/22:

132 × 7/22 = d

Simplifying the left side:

42 = d

Therefore, the diameter of the circle is 42 feet.

Answer:

D = 42

The decoded message is: "Steve Jobs".

Step-by-step explanation:

The given code is a sequence of binary digits, which represents the ASCII code of a message in binary form. To decode the message, we need to convert each 8-bit binary sequence into its corresponding ASCII character.

1010011 1110100 1100101 1110110 1100101 0100000 1001010 1101111 1100010 1110011

To decode this message, we split it into 8-bit sequences:

01010011 --> 'S'

01110100 --> 't'

01100101 --> 'e'

01110110 --> 'v'

01100101 --> 'e'

00100000 --> ' '

01001010 --> 'J'

01101111 --> 'o'

01100010 --> 'b'

01110011 --> 's'

Therefore, the decoded message is: "Steve Jobs".

1100101 = e

1110110 = v

1100101 = e

0100000 = (space)

1001010 = J

1101111 = o

1100010 = b

1110011 = s

So the decoded message is: "Steve Jobs"

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

Here are the steps to decode the given binary code:

Break the binary code into groups of 8 digits, as each group represents a single ASCII character.

Convert each group of 8 digits into its corresponding ASCII character using a binary-to-text converter or an ASCII code chart.

Write down the decoded ASCII characters in the order in which they appear in the original binary code.

Let's follow these steps to decode the given binary code:

We break this binary code into groups of 8 digits:

1010011 = 53

1110100 = 74

1100101 = 65

1110110 = 76

1100101 = 65

0100000 = 32

1001010 = 74

1101111 = 111

1100010 = 98

1110011 = 115

We convert each group of 8 digits into its corresponding ASCII character using an ASCII code chart:

53 = S

74 = t

65 = e

76 = v

65 = e

32 = (space)

74 = J

111 = o

98 = b

115 = s

We write down the decoded ASCII characters in the order in which they appear in the original binary code:

The scale of measurement used by the researcher is interval scale as the data is continuous and there are equal intervals between the values.

Mean = (1+2+4+5+7+11)/6 = 5

Median = (4+5)/2 = 4.5

Mode = There is no mode in the data set as none of the numbers are repeated.

Range = maximum value - minimum value = 11 - 1 = 10

Sample Variance = ((1-5)^2 + (2-5)^2 + (4-5)^2 + (5-5)^2 + (7-5)^2 + (11-5)^2)/(6-1) = 14.67

Standard Deviation = sqrt(sample variance) = sqrt(14.67) = 3.83

Mean + 2SD = 5 + 2*3.83 = 12.66, rounded to the nearest integer = 13.

According to the Empirical Rule, 68% of the sample lies within 1 standard deviation of the mean. Therefore, we need to find the values that are 1 standard deviation away from the mean:

Lower limit = Mean - SD = 5 - 3.83 = 1.17, rounded to the nearest integer = 1.

Upper limit = Mean + SD = 5 + 3.83 = 8.83, rounded to the nearest integer = 9.

So the number of leaves associated with 68% of the sample is between 1 and 9.

The length of the third side is 9.

A right-angled triangle is a triangle in which one of its angles is a right angle, meaning it measures exactly 90 degrees (π/2 radians). The other two angles are acute angles, meaning they measure less than 90 degrees.

In a right-angled triangle, the side opposite the right angle is called the hypotenuse. The other two sides are called the legs. The leg opposite to an acute angle is called the opposite side, and the leg adjacent to that angle is called the adjacent side.

The Pythagorean theorem is a fundamental concept in right-angled triangles. It states that the sum of the squares of the lengths of the legs of a right-angled triangle is equal to the square of the length of its hypotenuse. This theorem is often used to calculate the length of one side of a right-angled triangle when the lengths of the other two sides are known.

Let's call the missing side of the right triangle "x". We can use the Pythagorean theorem to solve for x, which states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

So, we have:

x² + 7² = (√130)²

Simplifying:

x² + 49 = 130

x² = 81

Taking the square root of both sides, we get:

x = 9

The percentage did the total yield, by weight, of her fruit harvest declined by approximately 24%, which is option B.

what is percentage ?

Percentage is a way of expressing a number or quantity as a fraction of 100. It is often denoted by the symbol % (percent). For example, 50% means 50 out of 100, or 50/100, or the equivalent fraction 1/2.
Percentages are commonly used in many real-world situations, such as in finance, statistics, and everyday life. They are often used to express changes, differences, or ratios between two values.

According to the question:

To solve this problem, we need to calculate the total weight of fruit harvested in the first year and the total weight of fruit harvested in the second year, and then calculate the percentage decline.

Total weight of fruit harvested in the first year = 40 + 12 = 52 pounds

After a 25% decline, the weight of pears in the second year = 40 - 0.25(40) = 30 pounds

After a 20% decline, the weight of plums in the second year = 12 - 0.20(12) = 9.6 pounds

Total weight of fruit harvested in the second year = 30 + 9.6 = 39.6 pounds

Percentage decline in the total yield of fruit harvest = [(52 - 39.6)/52] x 100% = 23.8%

Answer:

55 KG

Step-by-step explanation:

To convert pounds to kilograms, we can use the conversion factor 1 kg = 2.2 lbs.So,121 lbs = (121 lbs) * (1 kg/2.2 lbs)Simplifying the expression, we have121 lbs ≈ 55.0 kgRounding to the nearest tenth, we get the final answer:121 lbs ≈ 55.0 kg

Answer:

To convert 121 pounds into kilograms, we can use the conversion factor:

1 kg = 2.2 lb

Dividing both sides of this equation by 2.2, we get:

1 lb = 0.454545 kg (rounded to the nearest tenth, this is 0.5 kg)

Therefore, we can convert 121 pounds to kilograms by multiplying by 0.454545:

121 lb * 0.454545 kg/lb = 54.884545 kg

Rounding this to the nearest tenth gives:

54.9 kg

Therefore, 121 pounds is approximately equal to 54.9 kilograms when rounded to the nearest tenth.

In a right triangle, the tangent of an acute angle is the ratio of the length of the opposite side to the length of the adjacent side, the sine of an acute angle is the ratio of the length of the opposite side to the length of the hypotenuse, and the cosine of an acute angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

Using the side lengths given in the problem, we can identify that angle B is the acute angle opposite the side with length 5.

So, we have:

tanB = opposite/adjacent = 12/5

sinB = opposite/hypotenuse = 12/13

cosB = adjacent/hypotenuse = 5/13

Therefore, the values of the trigonometric functions for angle B in this right triangle are:

tanB = 12/5

sinB = 12/13

cosB = 5/13

Answer:

36 Units

Step-by-step explanation:

The circumference (C) of a circle is related to its diameter (d) by the formula:

C = πd

We can rearrange this formula to solve for the diameter:

d = C / π

In this case, the circumference of the circle is C = 113.04 units and π is approximately 3.14. Substituting these values into the formula, we get:

d = 113.04 units / 3.14

d ≈ 36 units (rounded to the nearest unit)

Therefore, the diameter of the circle is approximately 36 units.
