Graph a right triangle with the two points forming the hypotenuse. Using the sides, find the distance between the two points in simplest radical form.
(−2,4) and (7,−8)
The distance between the sides of the right-angled triangle is given as follows:
Recall that a right-angled triangle is one that has at least one side equal to 90°
In the question, we know the endpoints and the line hypothenus. To find the length of the hypothenuse, we can state:
Distance = [tex]\sqrt{(x2 - x1)^{2} +(y2 - y1)^{2} }[/tex]
Recall that the distance between the two points is given as (−2,4) for first point and (7,−8) for the second point.; Hence:
Distance = √[(-2+7)²+ (4+-8)²]
Distance = √(5²) + (-4)²
Distance = √(25+16)
Distance = √41
Hence the third point is (-2-8).

The angle B has a measure of 121 degrees
What are angles?Angles are formed when two or more lines intersect. This in other words means that angles is the measure of space between the intersection of rays or lines
How to determine the measure of the angle?The angles are given as
A = 2x + 29
B = 3x - 17
Also, we have:
The angles are vertical angles
Vertical angles are congruent angles
This means that
A = B
So, we have

Evaluate the like terms
x = 46
Substitute x = 46 in B = 3x - 17
B = 3 x 46 - 17

What amount of pure acid must be added to 400 mL of a 30% acid solution to produce a 75% acid solution?
Step-by-step explanation:
pure acid is a 100% acid solution.
x = ml of 100% solution
1×x + 0.3×400 = 0.75×(400 + x)
x + 120 = 300 + 0.75x
0.25x = 180
x = 720 ml
we must add 720 ml of pure acid to the 400 ml of 30% solution to create a 75% solution (1,120 ml in total).

An entry level web developer's annual pay is $56,940 based on 52 weeks per year. Due to the economy, his company is having to cut back on the number of weeks that it employs its web developers. If the firm cuts the work year to 50 weeks but keeps the same rate of pay, how much should the web developer expect his annual pay to decrease? Round your answer to the nearest dollar.
Based on the first entry level web developer salary paid, and the new work year, the amount the web developer can expect his annual pay to decrease by is $2,190
How to find the decrease in pay?First, find the weekly pay of the web developer in the first salary:
= 56,940 / 52
= $1,095 per week
The new salary of the web developer as a result of the work week becoming 50 weeks is:
= 1,095 x 50
= $54,750
The decrease in this annual pay to the web developer is:
= 56,940 - 54,750

What is unitary method?
It is the method by which we find the value of single unit form the value of multiple unit and value of multiple unit from the value of single unit.
Here,
500 g of strawberries cost £4.10
1 g of strawberries cost £[tex]\frac{4.10}{500}[/tex]
300 g of strawberries cost £[tex]\frac{4.10}{500} \times 300[/tex]
= £2.46
400 g of raspberries 300g of strawberries cost a total of £7.46
Let the cost of 400 g of raspberries be £x
so,
x + 2.46 = 7.46
x = 7.46 - 2.46
x = £5
cost of 400 g of raspberries = £5
cost of 1 g of raspberries = £[tex]\frac{5}{400}[/tex]
cost of 200 g of raspberries = £[tex]\frac{5}{400} \times 200[/tex]
= £2.5
cost of 300 g strawberries = £2.46
cost of 1 g strawberries = £[tex]\frac{2.46}{300}[/tex]
cost of 200 g of strawberries = £[tex]\frac{2.46}{300} \times 200[/tex]

Years of experience Salary 0 $40,000 1 $42,150 $44,260 $46,785 $48,820 $51,126 2 3 4 5 Use the equation for the line of best fit to predict the salary for an employee with 7 years of experience? (Round your answer to the nearest dollar) O $52,900 O $53,340 O $53,914 O $55,573
By using the equation for the line of best fit, the salary for an employee who has seven (7) years of experience is: D. $55,573.
What is a line of best fit?A line of best fit is a statistical tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association between a data.
In this scenario, the employee's salary would be plotted on the y-axis of the scatter plot while the years of experience would be plotted on the x-axis of the scatter plot.
By critically observing the scatter plot (see attachment) which models the data in the given table, an equation for the line of best fit is given by:
y = 2233.3x + 39940
Next, we would use the above equation for the line of best fit to predict the salary for an employee with 7 years of experience:
y = 2233.3(7) + 39940
y = 15,633.1 + 39940
y = 55,573.1 ≈ $55,573.

If a cylindrical barrel has a radius of 5.7 ft and a height of 8.4 ft, tripling the height of the concerned barrel will triple up its current volume.
As per the question statement, a cylindrical barrel has a radius of 5.7 ft and a height of 8.4 ft.
We are required to determine the dimension or dimensions which on tripling, will triple up the current volume of our question-mentioned barrel.
To solve this question, first we need to know the formula to calculate the volume of a cylinder, which goes as (π * r² * h)
Where [π = (22/7)], (r = radius of the cylinder)
And, (h = height of the cylinder).
Here, (r = 5.7 ft) and (h = 8.4 ft).
Now, considering [V = (π * r² * h)], where, ["V" is the volume]
if we triple our radius "r", our Volume "V₁" will become {π * (3r)² * h}
or, V₁ = 9πr²h
or, V₁ = 9(π * r² * h)
or, V₁ = 9V,
That is, 9 times the current volume. Hence, tripling the radius will not triple up the current volume of our concerned barrel.
Now, considering we triple our height "h", our Volume "V₂" will become {π * r² * 3h}
or, V₂ = 3πr²h
or, V₂ = 3(π * r² * h)
or, V₂ = 3V,
That is, 3 times the current volume. Hence, tripling the height will triple up the current volume of our concerned barrel.
As Proof,
Current Volume of our barrel = [(22/7) * (5.7)²* (8.4)]
= 857.74 ft²
And Volume of our barrel tripling the height = [(22/7) * (5.7)²* (3*8.4)]
= 2573.21 ft²
And, (2573.21/857.74) = 3.
Therefore, tripling the height of the concerned barrel will triple up its current volume, thus Proved.

Suppose that kellogg believes that the average weight for a box of frosted flakes is 18 ounces. As part of a quality control effort, they sample 30 boxes and find that the mean of those 30 boxes is 18. 2 ounces. Historical records show that the standard deviation of the filling process is 0. 32 ounces. How likely is it for the sample mean to have been 18. 2 ounces or larger if the actual mean is 18 ounces and the standard deviation of the filling process is 0. 32 ounces? round your answer to four decimal places.
Probability for the sample mean to have been 18.2 ounces or larger = 0.0003
Sample size, n = 30 boxes
Sample mean, [tex]\bar x[/tex] = 18.2 ounces
Population mean, μ = 18 ounces
Standard deviation of the population, σ = 0.32 ounces
We assume that this follows normal distribution.
Then the z-score, z = [tex]\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}} }[/tex]
= [tex]\frac{18.2-18}{\frac{0.32}{\sqrt{30}} }[/tex]
= 3.42
This z-score follows Standard Normal Distribution with mean = 0 and standard deviation = 1
Probability for the sample mean to have been 18.2 ounces or larger =
P(z ≥ 3.42) = 0.5 - P(0 < z < 3.423)

its B.4
Using percentage we can calculate that the team is expected to lose 4 matches.
A figure or ratio that is stated as a fraction of 100 is referred to as a percentage in mathematics. Although the abbreviations "pct," and occasionally "pc" is also used, the percent symbol "%" is most frequently used to denote it. A percentage is a number without any dimensions or established units of measurement.
By dividing the value by the entire value and multiplying the result by 100, the percentage may be computed. Calculating percentages using the formula (Value/Total Value)×100%.
Given in percentages the team will win 65% , team will draw =15%
Therefore in percentage the team will lose = 100 - ( 65 + 1 5 )% = 20 %
Now calculating the total number of matches the team will lose :
20% of 20 matches = 4 matches
Hence the team is expected to lose 4 matches out of 20.

Athletes who play baseball = 48 athletes
Athletes who don't play baseball = 33 athletes
Athletes who play basketball will be:
