You have 2 slices of pizza, and I gave you 3 slices of pizza. Can you write the simple expression to find the total number of slices of pizza?

Answer:

1) 2 should be added with 12 only and not with 6x as 6x and 2 are not like terms.

2) When adding polynomials, You should add only like terms.

Step-by-step explanation:

The steps done are:

Step 1: y-2=6x+12

Step 2: Add 2 on both sides

y-2+2=6x+12+2

Answer : y=8x+14

1) What mistake did I made?

You made a mistake in step 2,

When adding polynomials, you add only like terms. i.e

y-2+2=6x+12+2

y=6x+14

2 should be added with 12 only and not with 6x as 6x and 2 are not like terms.

2) Suggestion to avoid Such mistake in the future.

When adding polynomials, You should add only like terms.

Like terms are those that have same degree of variables i,e

2x and 3x, 2x^2 and 3x^2, 2 and 3 they all are like terms.

You can add 2x and 3x but can't add 2x and 2x^2 as they are not like terms.

So, while solving polynomials always add like terms.

Answer: s=u/tr

Step-by-step explanation:

In order to find the value of s, you need to isolate it on the side its on. Since t and r are being multiplied by s, you need to divide t and r from both sides. tsr/tr=s and u/tr remains in that format.

The data set 25 "fast food" represents drive-through service times for Burger King lunches, with a lower class limit of 70 seconds and a class width of 40.

The data can be organized into frequency tables to visualize the distribution of service times. To create the first class, we group all service times from 70 to 109 seconds

(70 + 40 - 1 = 109).

Then, we continue creating classes by adding 40 to the upper limit of the previous class and repeat the process until all data points have been assigned to a class.

The frequency table shows how many times a service time falls within each class interval, allowing us to see the distribution and make inferences about the typical service times at Burger King.

Further analysis such as calculating the mean and standard deviation can also be performed to better understand the data.

The following are the percentage increase or decrease of each employee to the nearest whole number;

Ruiz = 13%

Aria = 36%

Jack = 6%

The employee who had an increase of at least 10% and sold $425 or more in product is Ruiz.

Ruiz:

Percent increase = change in sales / march sales × 100

= ($450 - $400) / $400 × 100

= $50/$400 × 100

= 13%

Aria:

Percent increase = change in sales / march sales × 100

= ($420 - $310) / $310 × 100

= $110/$310 × 100

= 36%

Jack:

Percent decrease = change in sales / march sales × 100

= ($460 - $432) / $460 × 100

= $28/$460 × 100

= 6%

Therefore, Ruiz is the only employee who receives a bonus.

Answer:

72.5mph

Step-by-step explanation:

There is an easy way to work this. Divide the miles he drove by 2 so that you know how much he drove in 1/5 hours.

29/2= 14.5miles driven in 1/5 hours

Now, just multiply that number by 5 so that you know how many miles he drove in 5/5 hours (one full hour).

14.5*5= 72.5miles

You have the following expression:

(a + 2b)/ 5

In order to evaluate the previous expression for a = 1 and b = 2, you proceed as follow:

(a + 2b)/ 5 = ( 1 + 2(2) )/5

= ( 1 + 4 )/5

= (5)/5

= 1

Hence, the answer is 1.

It will take 57.78 years for your investment to reach $5000 with continuous compounding interest.

To determine how many years it will take for your investment to reach $5000 with continuous compounding interest, we can use the formula for continuous compound interest:

A = P * \(e^{rt}\)

Where:

A = Final amount (in this case, $5000)

P = Initial investment ($2000)

e = Euler's number (approximately 2.71828)

r = Interest rate (1.2% = 0.012)

t = Time (in years)

We can rearrange the formula to solve for t:

t = ln(A/P) / r

Substituting the given values:

t = ln(5000/2000) / 0.012

Calculating the value:

t ≈ ln(2.5) / 0.012

Using a calculator or software, we find:

t ≈ 57.78 years

When you are describing a rotation, you would have to include the center of the rotation, the angle of the rotation and the direction

When describing a rotation in mathematics, you must include several pieces of information in order to fully describe the transformation. The information that must be included is:

Center of rotation: The center of rotation is the point around which the rotation takes place.

Angle of rotation: The angle of rotation specifies how far the figure is rotated, typically measured in degrees or radians.

Direction of rotation: The direction of rotation can either be clockwise or counterclockwise.

Image: The image is the final position of the figure after it has been rotated.

For example, a description of a rotation might look like this: "A rotation of 90 degrees counterclockwise about the point (2,3)." This description specifies the center of rotation, the angle of rotation, the direction of rotation, and the image that results from the rotation.

In summary, to describe a rotation, you must specify the center of rotation, the angle of rotation, the direction of rotation, and the image that results from the rotation.

The probability that a randomly selected group of 16 individuals from the campus will be selected is 0.8023 or 80.23%

Based on the sign in the elevator of the college library, the limit of 16 persons and weight limit of 2,500 pounds need to be adhered to. To ensure compliance with both limits, we need to consider both the number of people and their weight.

Assuming that the distribution of weights of individuals on campus is approximately normal with an average weight of 155 pounds and a standard deviation of 29 pounds, we can use this information to estimate the total weight of a group of 16 randomly selected individuals.

The total weight of a group of 16 individuals can be estimated as follows:

Total weight = 16 x average weight = 16 x 155 = 2480 pounds

To determine if this total weight is within the weight limit of 2,500 pounds, we need to consider the variability in the weights of the individuals. We can do this by calculating the standard deviation of the total weight using the following formula:

Standard deviation of total weight = square root of (n x variance)

where n is the sample size (16) and variance is the square of the standard deviation (29 squared).

Standard deviation of total weight = square root of (16 x 29^2) = 232.74

Using this standard deviation, we can calculate the probability that the total weight of the group of 16 individuals is less than or equal to the weight limit of 2,500 pounds:

Z-score = (2,500 - 2,480) / 232.74 = 0.86

Using a standard normal distribution table or calculator, we can find that the probability of a Z-score less than or equal to 0.86 is approximately 0.8023.

Therefore, the probability that a randomly selected group of 16 individuals from the campus will comply with both the number and weight limits in the elevator of the college library is approximately 0.8023 or 80.23%.

An equation to represent the proportional relationship between the number of hours and the distance in miles is k=y/x.

Given that, Percy rides his bike 11.2 miles in 1.4 hours at a constant rate.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

The number of hours Percy rides x, and the distance in miles, y, that he travels

So, the proportional relationship is speed = y/x

Thus, 11.2/1.4

= 8 miles per hour

Therefore, an equation to represent the proportional relationship between the number of hours and the distance in miles is k=y/x.

angle between the ladder and the ground = 89.1°

Step-by-step explanation:

Go to the image below to get the visualisation for what's actually happening in the question and what they have asked for.

We are provided with adjacent which is 1.75 meters and hypotenuse with 110m and asked to find angle between the ladder and the ground.

Here, we will take angle between ground and ladder as x.

using sohcahtoa method,

\(\frac{adjacent}{hypotenuse} = cosx\)

\(\frac{1.75}{110} = cosx\)

\(x = cos^{-1} (\frac{1.75}{110}) \)

x = 89.1°
