The requried measure of length x in the right triangle is 16.15 units.

What are Pythagorean triplets?  

In a right-angled triangle, its sides, such as hypotenuse, and perpendicular, and the base is Pythagorean triplets.

Here,
For the given right-angle triangle,
Applying the Pythagoras theorem,
hypotenuse² = perpendicular² + base²
19² = 18² + x²
x = √19² - 10²
x = 16.15

Thus, the requried measure of length x in the right triangle is 16.15 units.

Answer:

X Intercept: (-2, 0)

Y Intercept: (0, 7)

Explanation:

Plug y = 0 into the equation and solve the resulting equation 7x = −14 for x. Plug x = 0 into the equation and solve the resulting equation −2y = −14 for y.

Answer:

(- 2, 0 ) and (0, 7 )

Step-by-step explanation:

To find the x- intercept let y = 0 in the equation and solve for x

7x - 2(0) = - 14, that is

7x = - 14 ( divide both sides by 7 )

x = - 2 ⇒ (- 2, 0 ) is the x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

7(0) - 2y = - 14, that is

- 2y = - 14 ( divide both sides by - 2 )

y = 7 ⇒ (0, 7 ) is the y- intercept

Sally has 5 times more sweets than paul but sally is feeling generous so she gives Paul 10. How many did Paul have in the first place

Answers

if sally has five times more sweets than paul and she gives paul ten, then she probably has 50 sweets, and if you divide 50 by 10 you get five. so Paul would have 5 candies in the first place. im not exactly sure but it’s an idea

Answer:

Paul had  5 sweets  in the first place ( Now he has 15)

Step-by-step explanation:

p= Paul   Sally = 5p

5p -10 = p+10

4p =  20

p = 5

Now Paul has 15 and Sally has 15 too

The ratio of pears to bananas in a fruit basket is 6 to 5. If there are 44 pears and bananas altogether, how many bananas must there be?

Answers

Answer:

20 Bananas

Step-by-step explanation:

we are going to apply the part to all method to solve this problem

Step one:

Given that the ratio of pears to banana is 6:5

the total ratio is 6+5= 11

and the total fruit is 44

Step two:

let the number of banana be x

applying the part to all method

5/11=x/44

cross multiply we have

11x=44*5

11x=220

divide both sides by 11

x=220/11

x=20

the bananas are 20 in numbers

A rose bush of height `h` is planted at an initial height of 3 feet. The bush is expected to grow an average of 0.5 feet per year. How tall will the bush be 3 years after planting? Show the work that leads to your answer (either in the text box below or on the white board to the right).

Answers

Answer:

The height is 4.5ft

Step-by-step explanation:

Given

[tex]Initial\ Height = 3\ ft[/tex]

[tex]Growth = 0.5\ ft[/tex] yearly

Required

Determine the height in 3 years

First, we need to determine the growth equation.

Represent the height with h and the years with x

So:

[tex]y = Initial\ Height + Growth * x[/tex]

[tex]y = 3 + 0.5 * x[/tex]

[tex]y = 3 + 0.5x[/tex]

To solve the required, we have that:

[tex]x = 3[/tex]

[tex]y = 3 + 0.5x[/tex] becomes

[tex]y = 3 + 0.5 *3[/tex]

[tex]y = 3 + 1.5[/tex]

[tex]y = 4.5[/tex]

Hence, the height is 4.5ft

35 out of the 50 employees at the sports shop are part-time employees. What percentage of the employees at the sports shop work part-time?

Answers

Answer:

70% Employee at the sports shop work part time.

Step-by-step explanation:

Given Data:

Total Employees = 50

Part-Time Employees = 35

Formula:

Percentage of Part-Time Employees =

(Part-Time Employees/Total Employees) x 100

=(35 / 50) x 100

=(0.7) x 100

= 70

so

The Percentage of Part-Time Employees is 70%.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data provided in the question,

The amount of floor required to make the recipe = 9/4 = 2.25 cups

But, Saron wants to make 3 1/2 times of recipe.

= 7/2 times or 3.5 times.

So, the amount of floor requried for this will be equal to,

3.5 × 2.25 = 7.87 cups of the floor.

Question 6(Multiple Choice Worth 5 points) (MC) New Technology Leads to Bigger Cities In the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas. Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. The abundance caused food prices to fall. The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas. As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization. In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents. The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in rural areas. Which sentence from the conclusion paragraph best rephrases the author's thesis? The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly.
