Michael needs 6 1/2 feet of metal flashing to complete a household project. He has two small pieces measuring 3 1/8 feet and 1 3/4 feet. How many feet of metal flashing does Michael need to purchase?

Answers

Michael needs to buy 1 5/8 feet more.

Length of metal flashing needed = 6 1/2

Since he already has two pieces we would add them together and this will be:

= 3 1/8 + 1 3/4

= 3 1/8 + 1 6/8

= 4 7/8

Therefore, we would subtract the above figure from 6 1/2 and this will be:

= 6 1/2 - 4 7/8

= 1 5/8

Therefore, Michael needs to buy 1 5/8 feet more.

Answer:

Michael needs to purchase 1 5/8 feet more of metal flashing.

Step-by-step explanation:

To have the same denominator in both fractions, you can multiply 4 by 2. This will turn out to be 8, resulting in 8 being our common denominator. To achieve this, multiply:

7 x 2 = 14 or 1 6/8

4 2 8

We next add both fractions together, resulting in:

3 1/8 + 1 6/8 = 4 7/8

The fraction 6 1/2 can also be expressed as 6 4/8, so to find out how much metal Michael still needs to purchase, subtract 4 7/8 from 6 4/8.

It mentions that angle 1 is congruent to angle 2. They have the same angle measure. This allows us to replace angle 1 with angle 2 (because they're effectively the same thing).

We can say
(angle 1) + (angle 3) = 90
(angle 2) + (angle 3) = 90
notice the replacement in bold

The second equation is an algebraic way of saying "angle 2 and angle 3 are complementary"

What are the next three numbers 1, -5, 25, -125,

Answers

If you would like to know the following three numbers, you can do this using the following steps:

1, -5, 25, -125, x, y, z
1 * (-5) = -5
-5 * (-5) = 25
25 * (-5) = -125
x = -125 * (-5) = 625
y = 625 * (-5) = -3125
z = -3125 * (-5) = 15625

The correct result would be 625, -3125, and 15625.

It be 625, -3,125 and 15,625

The angle of elevation from a car to the top of an apartment building is 48 degrees. If the angle from another car that is 22 feet directly in front of the first car is 64 degrees. How tall is the building? I know it involves trig, but after an hour of thought i give up on guessing.

Answers

The required height of the building is 53.31 feet.

What is a right angle triangle?

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.

Given that,

Angle of elevation from the first car A to the top of the apartment building = 48 degrees,

Angle of elevation from the second car B to the top of the apartment building = 64 degrees.

Also, car B is 22 feet above the car A.

Let the height of the building is h feet.

And distance from the car B to the building is x feet.

Use formula of tan θ,

tan 64 = h / x

2.050 = h/x

x = h / 2.050 (1)

And tan 48 = h / x + 22
1.1106 = h / x+ 22 (2)

By solving equation (1) and (2)

1.1106 = h / (h/2.050 + 22)

1.1106 = 2.050h / h + 45.1

1.1106h + 50.08 = 2.050h

0.9394 h = 50.08

h = 53.31

The height of the building is 53.31 feet.

To the StudentContents: Members of the PEAMathematics Department have written the materialin this book. As youwork through it, you will discover that algebra, geometry, andtrigonometry havebeen integrated into a mathematical whole. There is no Chapter 5, noris there a section ontangents to circles. The curriculum is problem-centered, rather thantopic-centered.Techniques and theorems will become apparent as you work through theproblems, and youwill need to keep appropriate notes for your records — there are noboxes containingimportant theorems. There is no index as such, but the reference sectionthat starts on page201 should help you recall the meanings of key words that are definedin the problems(where they usually appear italicized).Comments onproblem-solving: You should approacheach problem as an exploration.Reading each questioncarefully is essential, especially since definitions, highlighted initalics, areroutinely inserted into the problem texts. It is important to make accuratediagrams wheneverappropriate. Useful strategies to keep in mind are: create an easierproblem, guess andcheck, work backwards, and recall a similar problem. It is importantthat you work on eachproblem when assigned, since the questions you may have about aproblem will likelymotivate class discussion the next day.Problem-solvingrequires persistence as much as it requires ingenuity. When you get stuck,or solve a problemincorrectly, back up and start over. Keep in mind that you’re probablynot the only one whois stuck, and that may even include your teacher. If you have takenthe time to thinkabout a problem, you should bring to class a written record of yourefforts, not just ablank space in your notebook. The methods that you use to solve aproblem, thecorrections that you make in your approach, the means by which you testthe validity of yoursolutions, and your ability to communicate ideas are just as importantas getting thecorrect answer.About technology: Many of theproblems in this book require the use of technology(graphing calculatorsor computer software) in order to solve them. Moreover, you areencouraged to usetechnology to explore, and to formulate and test conjectures. Keepthe followingguidelines in mind: write before you calculate, so that you will have a clearrecord of what youhave done; store intermediate answers in your calculator for later use inyour solution; payattention to the degree of accuracy requested; refer to your calculator’smanual when needed;and be prepared to explain your method to your classmates. Also,if you are asked to“graphy= (2x−3)=(x+ 1)”, for instance,the expectation is that,although you mightuse your calculator to generate a picture of the curve, you shouldsketch that picture in your notebook oron the board, with correctly scaled axes.
