factorise completely 3m^2-48​

Answers

Answer 1

Answer:

3 (m^2 - 16)

Step-by-step explanation:

factoring means taking out a common multiple of all the terms in the expression

in this case, if you multiply 3 and m^2, 3 and -16, you would get 3m^2-48​

so you take the three and put it outside of the parenthesis that contains the factored terms

this leaves you with 3 (m^2 - 16)

The smiths went to Larosa's for dinner and spent $42.50 on dinner. There is a 6.5% tax and they want to give a tip of 20% before the tax is added. What is the total price of their bill?

Answers

Answer:

Step-by-step explanation:

cost of dinner = $42.5

Tax = 6.5%

Tip = 20%

Total amount percent on food  = 26.5%

Amount paid on the original price = 26.5% of $42.5

Amount paid on the original price = 0.265*42.5 = $26.5625

Total price of the bill = $42.5 + $26.5625

Total price of bill = $69.0625

Answer:

The ladder is 35.71 feet up the building

Step-by-step explanation:

Here, we want to calculate how far up the building is the ladder placed

We should picture a right angled triangle with hypotenuse 50 and one of the other sides as 35

To find the height in this case, we proceed to use Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides

In this case, let the height be

50^2 = 35^2 + h^2

h^2 = 50^2-35^2

h^2 = (50+35)(50-35)

h^2 = (85)(15)

h^2 = 1275

h = square root of 1275

h = 35.71 ft

Jackson buys a softball for $15 plus a 6% tax. Avery buys a volleyball for $13 plus a 6% tax. Enter the difference in the amount Jackson and Avery paid, including tax. Round your answer to the nearest cent.

Answers

Answer:

The answer is that the difference in the amount that Jackson and Avery paid including tax is $1.31.

Step-by-step explanation:

First, you have to calculate the amount they paid including the tax by finding the 6% of each price and adding this amount to the price:

-Jackson: $15*6%=0.09

$15+$0.09=$15.09

-Avery: $13*6%=$0.78

$13+$0.78=$13.78

Now, you have to subtract to find the difference:

$15.09-$13.78=$1.31

According to this, the answer is that the difference in the amount that Jackson and Avery paid including tax is $1.31.

Step-by-step explanation:

You would have to add 2 and 9 and then divide by 2. (Find the average of the two)

2 + 9 = 11

Describe your approach to solving a given triangle. Include specific details about what you look for and how you start the problem. What are the important pieces of information that affect how you solve the triangle?
(edginuity)

Answers

Answer:

In order to solve a right triangle, you must first figure out which angle is the right angle. Knowing the right angle will also tell you which side is the hypotenuse, since the hypotenuse will always stand opposite the right angle. In this text, for the sake of consistency, in all triangles we will designate angle C as the right angle, and side c and the hypotenuse. To finish solving a right triangle, you then must either know the lengths of two sides, or the length of one side and the measure of one acute angle. Given either of these two situations, a triangle can be solved. Any further information about a triangle may be helpful, but it is not necessary.There are four basic techniques to use in solving triangles.Using the Pythagorean Theorem, once two sides are known, the third side can be calculated.Using the fact that the acute angles of a right triangle are complementary, once one acute angle is known, the other can be calculated.Using the definitions of the trigonometric functions, any two parts of a triangle can be related in an equation to equal a third part.Using the definitions of the inverse trigonometric functions, any two sides of a triangle can be related in an equation to equal the inverse function of an unknown acute angle

Java Please simplify/evaluate 7x - 2x + 30 Read very very carefully and it says what to choice). In this lesson you learned about time lines and how Thematic Time Lines show events pertaining to a particular historical theme. You will create a time line of important events related to a single theme from prehistory to A.D. 1600. ( You will have three lessons in which to complete): 1: Themes)--> For this assignment you will create a thematic time line of five events. To begin with, however, you will first decide on two possible themes for the time line. You will choose one of these themes. Choose two themes from the list below that you would consider for your Thematic Time Line: Politics, The Miltary, and Economics. Religion, Philosophy, and Learning. Science, Technology, and Innovations. Literature, Visual Arts, Theater, and Music. To give you some practice in associating events with themes, choose the event that would be included on a time line for each of the following themes: ---> I posted a picture of the practice sheet. ( 2: Events ---> Choose five events for each of the two themes you chose in Step 1 ( for a total of ten events). Your final time line will cover only five events for one theme. The events must have occurred within the period under study ( Prehistory to A.D. 1600). You may wonder how you can represent such a long time span, from prehistory to A.D. 1600, with only five events. It won't be easy. You must choose events that you believe are major milestones of this period; events that had a major impact on history. Later in the assignment, you will defend your choices and explain why you included each event on your time line. ( To give you some practice choosing events, choose the one event in each group below that you believe is the most important; the one event that had the biggest effect on history. Below, you will defend your choice by explaining why you think it was the most important. (Group A--> Second century B.C: Romans build aqueducts to supply water to cities. A.D. Second century: Pulp papermaking process is invented in China. Seventh century: Muslim architects build mosques with domes. ( Group B--> c. Second century B.C: Zhang Qian helps establish the Silk Road. c. A.D. 1080: Venice and Byzantium sign a treaty governing commerce. 1158: Munich, Germany, becomes center of salt trade in Europe). Now it's time to choose five events for each of the two themes you chose. First you'll need to review the major events from prehistory to A.D. 1600. A convenient way to do this would be to look at the time lines for Chapters 1 through 17 that appear at the beginning of each chapter. As you review this time period, write down events that are good candidates for thematic time lines related to the themes you chose. Remember that you are only interested in events that are related to these two themes. Try to compile a list of about 10 events for each theme. Don't write long entries; just jot down key ideas. Now choose the five most important events for each theme. Write these events in the corresponding section of the Graded assignment sheet. Include a time for each event ( such as 509 B.C., A.D. second century, 1066, and so on). (Part 3. Select a Theme: Select one of the two themes you chose earlier. You will create a thematic time line based on this theme. Write this theme in the corresponding section. ( Part 4: --> Rationale/Defense of Entries: You now have a theme and five events for a Thematic time line covering prehistory to A.D. 1600. You need to defend your choices for the events by explaining why you included each one. For each event, be as specific as possible as you answer the following questions: 1) Why is this event important?, 2) What impact did this event have on society?, 3) How is the world different because of this event?, 4) Why is this event more significant than most other events within the theme? For each event you selected in groups A and B above, write a short paragraph that defends your choice and provides a rationale for why you think it is the most important of the three. Group A: and Group B: Write a short paragraph for each event that explains why you included the event on your time line. ( Part 5:--> Create a thematic time line for the theme you chose that includes, at a minimum, the five events you selected for that theme. Follow these guidelines as you develop the time line. 1) Your time line can include up to ten events.( The time line must included at a minimum five events. 2) Each entry on the time line should include a date( year or century), a description of the event, and an image. The image can be something you illustrate or find on the internet. 3) Include a title for the time line that incorporates the time line's theme. [ Will Mark Brainliest ]. Need Help ASAP Please.
