Answer:

$1,489.88 (nearest cent)

Step-by-step explanation:

To calculate gross pay, multiply the number of hours worked by the pay per hour.

Warren worked 36.5 hours one week and 32 hours the week before.

Therefore, the total number of hours Warren worked was:

Multiply the total number of hours worked by Warren's rate of pay of $21.75 per hour:

Therefore, Warren's gross pay for the two weeks was $1,489.88 (nearest cent).

Answer:

$1489.875

Step-by-step explanation:

Warren's gross pay for 36.5 hours last week can be calculated as follows:

Gross pay for 36.5 hours = $21.75/hour * 36.5 hours = $793.875

Similarly, Warren's gross pay for 32 hours the week before can be calculated as follows:

Gross pay for 32 hours = $21.75/hour * 32 hours = $696

Adding the gross pay for the two weeks, we get:

Gross pay for 2 weeks = $793.875 + $696 = $1489.875

well, from 1990 to 1998 is 8 years, and we know the amount went from $4800 to $6300, let's check for the rate of growth.

\(\qquad \textit{Amount for Exponential Growth} \\\\ A=P(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$6300\\ P=\textit{initial amount}\dotfill &\$4800\\ r=rate\to r\%\to \frac{r}{100}\\ t=\textit{years}\dotfill &8\\ \end{cases} \\\\\\ 6300=4800(1 + \frac{r}{100})^{8} \implies \cfrac{6300}{4800}=(1 + \frac{r}{100})^8\implies \cfrac{21}{16}=(1 + \frac{r}{100})^8\)

\(\sqrt[8]{\cfrac{21}{16}}=1 + \cfrac{r}{100}\implies \sqrt[8]{\cfrac{21}{16}}=\cfrac{100+r}{100} \\\\\\ 100\sqrt[8]{\cfrac{21}{16}}=100+r\implies 100\sqrt[8]{\cfrac{21}{16}}-100=r\implies \stackrel{\%}{3.46}\approx r\)

now, with an initial amount of $4800, up to 2007, namely 17 years later, how much will that be with a 3.46% rate?

\(\qquad \textit{Amount for Exponential Growth} \\\\ A=P(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &4800\\ r=rate\to 3.46\%\to \frac{3.46}{100}\dotfill &0.0346\\ t=years\dotfill &17\\ \end{cases} \\\\\\ A=4800(1 + 0.0346)^{17} \implies A=4800(1.0346)^{17}\implies A \approx 8558.02\)

The cost price is always used to compute the loss or gain percentage.

No. of packets purchased = 250

Cost price of 250 packets = 8 (250) = 2000

Selling price of 70% of packets =  11 per packet

Selling price of 30% of packets =  9 per packet

II) Selling price of 70% of packets

70% of 250

= 70/100×250

= 175

Selling price of 70% of packets is 11 per packet

S. P of  70%  = 175 * 11

                      = Rs.1925

S. P of  30% = 250- 175 = 75

                     =75* 9

                    = Rs.675

Selling price of 250 packets =  Rs.2600

So, option (a) is correct.

III)  30% of 250

= 30/100×250

= 75

So, option (c) is correct.

IV ) Gain = Selling price - Cost price

              =2600 - 2000

              = 600

So, option (d) is correct.

I) Gain % = Gain/ C.P * 100

              = (600/ 2000) * 100

              = 30 %

So, option (c) is correct.

V) Gain % is always calculated on Cost price

So, option (a) is correct.

Answer:

4x - 2y = 2

Step-by-step explanation:

Given that (1, 1 ) is a solution then it must satisfy the equation

Consider the equations given

2x + y = 2 → 2(1) + 1 = 2 + 1 = 3 ≠ 2 ← not True

4x - 2y = 2 → 4(1) - 2(1) = 4 - 2 = 2 ← True

2x - 2y = 2 → 2(1) - 2(1) = 2 - 2 = 0 ≠ 2 ← not True

x + y = 4 → 1 + 1 = 2 ≠ 4 ← not True

Thus

4x - 2y = 2 completes the system.

Answer:

-49/15

Step-by-step explanation:

To determine the position of point A on the number line, we need to subtract the length of segment AB from the position of point B.

Given that the position of point B is 2/5, we can subtract the length of AB, which is 3 2/3, from 2/5.

To subtract fractions, we need to find a common denominator. The least common denominator for 3/3 and 5 is 15.

Converting 3 2/3 to an improper fraction:

3 2/3 = (3 * 3 + 2)/3 = 11/3

Subtracting the fractions:

2/5 - 11/3 = (2 * 3 - 11 * 5)/(5 * 3) = (6 - 55)/15 = -49/15

The position of point A is -49/15 on the number line.

The zeroes of the function f(x) = 3(x²-25)(4x^2+4x+1) are x = -5, x = 5, x = -0.5 - 0.5i, and x = -0.5 + 0.5i.

To find the zeroes of the given function f(x), we set f(x) equal to zero and solve for x. The function f(x) can be factored as follows: f(x) = 3(x²-25)(4x²+4x+1).

The first factor, (x²-25), is a difference of squares and can be further factored as (x-5)(x+5). The second factor, (4x²+4x+1), is a quadratic trinomial and cannot be factored further.

Setting each factor equal to zero, we have three equations: (x-5)(x+5) = 0 and 4x²+4x+1 = 0. Solving the first equation, we find x = -5 and x = 5 as the zeroes.

To solve the second equation, we can use the quadratic formula: x = (-b ± √(b²-4ac))/(2a), where a = 4, b = 4, and c = 1. Plugging in these values, we get x = (-4 ± √(4^2-4*4*1))/(2*4). Simplifying further, we have x = (-4 ± √(16-16))/(8), which simplifies to x = (-4 ± √0)/(8). Since the discriminant is zero, the quadratic has complex conjugate zeroes. Therefore, x = -0.5 - 0.5i and x = -0.5 + 0.5i are the remaining zeroes of the function.

In summary, the zeroes of the function f(x) = 3(x²-25)(4x²+4x+1) are x = -5, x = 5, x = -0.5 - 0.5i, and x = -0.5 + 0.5i.

For the data generated by the questionnaire item that asked students to indicate their class rank in college, the appropriate measure of location would be the mode.

The mode is the value that occurs most frequently in a dataset and represents the most common response. In this case, the mode would indicate the most common class rank among the students surveyed. It is important to note that the use of the mode as a measure of location is most appropriate when dealing with nominal or ordinal data, such as class rank, where there is no inherent numerical relationship between the categories.

Other measures of location, such as the mean or median, are more appropriate for interval or ratio data where there is a meaningful numerical relationship between the values.

Answer:

Step-by-step explanation:

If the target behavior is recorded whenever it occurs at any point within the scoring interval, the measurement procedure used is called continuous recording or event recording. This method involves observing and recording each instance of the behavior without considering its duration or intensity.

Continuous recording is typically used when the target behavior is discrete and occurs relatively infrequently or has a short duration. With this measurement procedure, each occurrence of the behavior is recorded as a separate event, regardless of when it starts or ends within the scoring interval. Examples of behaviors that can be measured using continuous recording include vocalizations, hand clapping, or instances of aggression.

Continuous recording provides a comprehensive account of the frequency or rate at which the behavior occurs, allowing for a detailed analysis of its occurrence patterns. This method is particularly useful when a precise count of behavior instances is needed and when the duration or intensity of the behavior is not a focus of measurement.

Many psychologists do not use hypnosis in their practices, it is because they know very little about it and are wary of it as a result.

A psychologist is a specialist in the field of psychology who investigates behavior as well as mental states, perceptual, cognitive, emotional, and social processes. They frequently experiment with, observe, and interpret how people interact with one another and their surroundings as part of their work. Someone who examines the mind and behavior is called a psychologist. When people hear the word "psychologist," they frequently picture talk therapy; however, this profession actually covers a wide range of specialization areas, including things like animal studies and organizational behavior.

Answers are ,Right triangle with legs 3 meters and 33 meters, Right triangle with legs 1 meter and 15 meters, Right triangle with legs 12 meters and 140 meters, Right triangle with legs 12 meters and 150

what is Right triangle ?

A right triangle is a triangle that has one angle equal to 90 degrees (a right angle). The other two angles are acute angles (less than 90 degrees). The side opposite to the right angle is called the hypotenuse, and the other two sides are called legs.

In the given question,

The ratio of the legs of the right triangle for a ramp should be 1:12, which means that for every 1 inch of rise, there should be 12 inches of ramp length. To calculate the angle of inclination, we can use the inverse tangent function, which gives us the angle whose tangent is equal to the ratio of the legs. The angle of inclination should be less than or equal to 4.8 degrees.

Let's calculate the angle of inclination for each ramp design:

Right triangle with legs 3 meters and 33 meters:

The ratio of the legs is 3:33, which simplifies to 1:11. The length of the ramp is 11 times the height of the rise. The angle of inclination is:

arctan(1/11) ≈ 4.76 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 1 meter and 15 meters:

The ratio of the legs is 1:15. The length of the ramp is 15 times the height of the rise. The angle of inclination is:

arctan(1/15) ≈ 3.81 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design also meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 12 meters and 140 meters:

The ratio of the legs is 12:140, which simplifies to 3:35. The length of the ramp is 35 times the height of the rise. The angle of inclination is:

arctan(3/35) ≈ 4.56 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 12 meters and 150 meters:

The ratio of the legs is 12:150, which simplifies to 2:25. The length of the ramp is 25 times the height of the rise. The angle of inclination is:

arctan(2/25) ≈ 4.62 degrees

The angle of inclination is less than or equal to 4.8 degrees, so this ramp design meets the requirements of the Americans with Disabilities Act.

Right triangle with legs 24 meters and 240 meters:

The ratio of the legs is 24:240, which simplifies to 1:10. The length of the ramp is 10 times the height of the rise. The angle of inclination is:

arctan(1/10) ≈ 5.71 degrees

The angle of inclination is greater than 4.8 degrees, so this ramp design does not meet the requirements of the Americans with Disabilities Act.

Therefore, the ramp designs that meet the requirements of the Americans with Disabilities Act are:

Right triangle with legs 3 meters and 33 meters.

Right triangle with legs 1 meter and 15 meters.

Right triangle with legs 12 meters and 140 meters.
