Answer 1

Answer:

Side a = 20.8

Side b = 20.5

Side c = 30

Side d = 2

Side e = 12.6

Step-by-step explanation:

We need to know what X is here is the equation:

3.2a+8+12.6+[tex]\frac{1}{2}a[/tex]+5(a+2)+(6a-3.5)=85.9

After doing the math you get a=4.

Apply this to each side and get the answer.

Side a = 20.8

Side b = 20.5

Side c = 30

Side d = 2

Side e = 12.6

Check

20.8+20.5+30+2+12.6=85.9

Answer:

If you want to factor it, it will be 4(m+1).If not factored, it will be 4m+4

Step-by-step explanation:

m+3m+2+2

m+3m = 4m

2+2 = 4

4m+4

To factor that, you can take out 4 as a common factor, so it will be (4)(m+1)

Find the area of the polygon. A = __ft squared

Answers

Answer:

28.5^2

Step-by-step explanation:

The formula is, b(base)+c(height)= b+c over 2. b+c/2.

B=19ft in this problem.

C=38ft

Knowing this, we can further simplify.

19+38/2

Now, we add 19 and 38.

(57)

57/2= 28.5

So, the anwser is 28.5^2

Solve for a:

a – 17 = -15
A. a = -32
B. a = 2
C. a = 32
D. a = 12

Answers

Answer:

Step-by-step explanation:

a-17=-15

so the whole point of solving problems like this is to get the variable on one side (a in this case) and the constants on the other side (-17 and -15 in this case).

so to get rid of the 17 because its negative you have to add 17 or do the inverse sign but whatever you do to on side you have to do to the other side so you add 17 to both side

-17+17 they cancel out

-15+17=2

so now we get that a=2

your answer would be B

hope this helps :D

The value of the expression at y = 2.5 is 6.25.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

y²

Substitute y = 2.5

= y²

= 2.5²

= 2.5 x 2.5

= 6.25

Thus,

The value is 6.25.

Find the value of the fraction 4/15 and multiply the result by 100% to obtain the final answer:

4/15 = 0.26667

Multiplied by 100%, 0.26667 becomes 26.7%: the percentage change in the number of students

In a regular polygon, the measure of an interior angle is 6.5 times the measure of an exterior angle. How many sides does the polygon have?

Answers

Answer:

15 sides

Step-by-step explanation:

Always the sum of interior angle and exterior angle = 180

Let the exterior angle = x

Interior angle = 6.5 *x = 6.5x

x + 6.5x = 180

7.5x = 180

x = 180/7.5

x = 24

Exterior angle = 24°

Sum of exterior angles of any polygon = 360

number of side = Sum of exterior angles ÷ measure of each exterior angle

= 360 ÷ 24

= 15

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 details are used to support the main fact in the fifth paragraph?
