Answer:
The ordered pair for point B after it has been reflected over both the x and y-axis is (4, 6).
This is due to the rule for reflecting over the x-axis, which is to negate the value of the y-coordinate of each point, but leave the x-value the same. This means that after reflecting point B over the x-axis, it's new coordinates would be (-4, 6).
The rule for reflecting over the y-axis is to negate the value of the x-coordinate of each point, but leave the y-value the same. This means that after reflecting point B' over the y-axis, it's new coordinates would be (4, 6).
What is the measure of each angle in a regular polygon with 9 sides?
Answer: 140
Step-by-step explanation:
Measure of each angle in a regular polygon can be determined by the equation 180(n-2)/n, where n is the number of sides. Plug in 9 to get 140 degrees.
shandra has a bag that contains pineapple chews, cherry chews, and peach chews. she performs an experiment. shandra randomly removes a chew from the bag, records the result, and returns the chew to the bag. shandra performs the experiment 57 times. the results are shown below: a pineapple chew was selected 8 times. a cherry chew was selected 25 times. a peach chew was selected 24 times. if the experiment is repeated 400 more times, about how many times would you expect shandra to remove a pineapple chew from the bag? round your answer to the nearest whole number.
Shandra is expected to select a pineapple chew about 56 times in the next 400 selections.
Based on the given results, Shandra selected a pineapple chew 8 times out of 57 selections. To estimate the expected number of times she would select a pineapple chew in the next 400 selections, we can use the proportion of pineapple chews selected in the first 57 selections:
The proportion of pineapple chews selected = 8/57
To estimate the expected number of pineapple chews in the next 400 selections, we can multiply the proportion by the total number of selections:
Expected number of pineapple chews in the next 400 selections = (8/57) x 400
expected number of pineapple chews in the next 400 selections = 56.14
Rounding to the nearest whole number, we would expect Shandra to select a pineapple chew about 56 times in the next 400 selections.

14 Jun 2018 · Norman is 12 years older than Michael. In 6 years, he will be twice as old as Michael. How old is Michael now? (A) 3 (B) 6 (C) 12
Michael is now (B) 6 years old.
Let's start by defining variables for the current ages of Norman and Michael.
Let N be Norman's current age, and M be Michael's current age.
From the problem statement, we know that N = M + 12 (Norman is 12 years older than Michael).
We also know that in 6 years, Norman will be twice as old as Michael.
So we can set up the following equation:
N + 6 = 2(M + 6)
Substituting N = M + 12 into the equation, we get:
M + 12 + 6 = 2(M + 6)
Simplifying:
M + 18 = 2M + 12
M = 6
Therefore, Michael is currently 6 years old.

a vendor at the basket ball game go to 405 bottles of water on Saturday she sold 127 fewer bottles on Sunday she sold 178 bottles on Sunday
The correct answer is 178 bottles of water sold on Sunday.
What is vendor ?Vendor is a person or a company that sells goods or services. The term is commonly used to refer to individuals who sell items at events, markets, or street stalls. Vendors may sell a variety of products, including food, drinks, clothing, accessories, and more
If the vendor sold 405 bottles of water on Saturday, and sold 127 fewer bottles on Sunday, then on Sunday she sold 405 - 127 = 278 bottles of water.
However, the question states that she actually sold 178 bottles of water on Sunday, so the number of bottles she sold on Sunday was incorrect.

The manager of a farmer's market has 350 lb of grain that costs $1.40 per pound. How many pounds of meal costing $0.80 per pound should be mixed with the 350 lb of grain to produce a mixture that costs $1.10 per pound?
350 pounds of the meal should be added to the grain to produce a mixture that costs $1.10 per pound.
What is meant by addition?
In mathematics, addition is the process of fusing two or more integers. The numbers being added are known as addends, while the outcome of the addition process, or the final response, is known as the sum. It is one of the fundamental mathematical operations we employ on a daily basis. We add numbers in many different contexts.
Let the amount of meal mixed with the grain be 'x' pounds.
Now, Total price of the mixture = x*0.80 + 350*1.40 = (x+350)*1.10
350*(1.40 - 1.10) = x*(1.10 - 0.80)
350*0.3 = x*0.3
x = 350
Therefore, the amount of meal that should be added to the grain is 350 pounds.

A plane left Kennedy Airport on Tuesday morning for a 730-mile, 6-hour trip. For the first part of the trip, the average speed was 115 mph. For the remainder of the trip, the average speed was 125 mph. How long did the plane fly at each speed?
A. First part of trip: __ h
B. Second part of trip: __ h
The first part of the trip took approximately 6.39 hours and the second part of the trip took approximately 5.84 hours.
Solving for Time and Average Speed in a Two-Part Plane TripIn this problem, we are given the distance, total time, and average speeds for two parts of a plane trip.
Using the formula for average speed
Distance = average speed x time,
We can set up two equations and solve for the times spent flying at each speed.
We define t₁ as the time spent flying at 115 mph and t₂ as the time spent flying at 125 mph.
From the equation
730 miles = 115 mph x t₁,
we solve for t₁ and get
t₁ = 6.391304347826087 hours.
Similarly, from the equation
730 miles = 125 mph x t₂,
we solve for t₂ and get
t₂ = 5.84 hours.
Therefore, the plane flew at an average speed of 115 mph for approximately 6.39 hours and at an average speed of 125 mph for approximately 5.84 hours.

(5pts) c) oh no! where is our head at today? we completely forgot to mention that the bucket has a hole in the bottom. it only weighs 35lb when it reaches the top, due to the water leaking out at a constant rate. now compute the real work required to lift the bucket from the bottom of the well to the top of the well. (recall that the bucket is being lifted at a constant rate, as well.) (5pts)
If the weight of the bucket is 70 lb , then the work required to lift the bucket from bottom is 135240 foot-pounds .
We use the formula : Work = Force × Distance to calculate the work done
where "Force" is weight of bucket filled with water and "Distance" is height it is lifted.
The weight of bucket filled with water is = 70 pounds.
We convert this to a force in pounds force, by using g = 32.2 feet per second squared ;
So , Force = Weight × Gravity
⇒ 70 lb × 32.2 ft/s² = 2254 lb-ft/s²
The distance that the bucket is lifted is = 60 feet ;
So , work required to lift bucket from bottom of well to top is :
⇒ Work = Force × Distance = 2254 lb-ft/s² × 60 ft
⇒ 135240 foot-pounds
Therefore , it will require 135240 foot-pounds of work to lift the bucket filled with water from the bottom of the well to the top.

How to figure out the area of a right angle triangle
The area of a right triangle can be found by multiplying half of the length of the base by the height.
The formula for the area of a right triangle is:
Area = (1/2) * base * height
It is important to note that the base and height must be perpendicular to each other, forming a right angle in the triangle. If the triangle is not a right triangle, then the area cannot be found using this formula.
To use this formula, simply measure the length of the base and height and plug these values into the formula. The result will be the area of the triangle, expressed in square units.
It is also worth noting that the height and base of a right triangle can be any two sides that form a right angle, not just the sides that are labeled as the base and height.

A sample size of 44 is needed to assure with 95% confidence that the sample mean will not differ from the population mean by more than 2.5 units.
To find the sample size needed to assure with 95% confidence that the sample mean will not differ from the population mean by more than 2.5 units, we can use the formula:
n = [ (z * σ) / E ]^2
where n is the required sample size, z is the critical value for the desired confidence level (95% confidence level corresponds to a z-value of 1.96), σ is the population standard deviation (given as the square root of the variance, which is √(70) ≈ 8.37), and E is the maximum error, or the maximum difference between the sample mean and population mean that we are willing to tolerate (which is given as 2.5 units).
Substituting the given values into the formula, we get:
n = [ (1.96 * 8.37) / 2.5 ]^2
n ≈ 43.48
Rounding up to the nearest whole number, we get a required sample size of n = 44.
Therefore, a sample size of 44 is needed to assure with 95% confidence that the sample mean will not differ from the population mean by more than 2.5 units, assuming a normal distribution with a population variance of 70.
