Classify the following triangle. Check all that apply.
I A. Obtuse
B. Acute
C. Scalene
D.slught
E. Isosceles
F. Equilateral

Answers

Answer: B. Acute and F. Equilateral

Step-by-step explanation: Acute triangles contain interior angles that are less than 90 degrees. All triangles must have interior angles that add to 180 degrees when combined. In this triangle, all interior angles are equal. Therefore, we can divide 180 by the 3 angles to find that each angle is 45 degrees. 45 degrees is less than 90, so it is an Acute Triangle.

In equilateral triangles, all sides have the same length. We can see in the diagram that all of the sides contain the same marking, indicating they are the same length. So, the triangle is also equilateral.

you and a friend go to taco bell for lunch. you order four soft tacos and two burritos and your bill totals $11.50. your friend's bill $12.00 for three soft tacos and three burritos. how much do the tacos and burritos cost?​

Answers

Answer:

Answer b = $ 2.25 dollars

             s = $ 1.75 dollars

Please see how to do, it is good to know the answers but if you know how to solve it thats even better!!

Step-by-step explanation:

Let : s = soft tacos

       b = burritos

Step 1: 11.50 = 4s + 2b

           12.00 = 3s +3b

Step 2: Solve using subtraction

12 =3s + 3b

-1 (11.50 = 4s + 2b)  _ times by -1 so you can subtract

-11.50 = -4s -2b      _ once you do this bring the other equation

12.00 = 3s + 3b      _ then subtract/ add

_____________+__

0.50 = -s + b          _ add s to both sides

s + 0.50 = b             _ now you can plug in b into the original equation

12.00 = 3s + 3(s + 0.50)   _distribute the 3 to the s and 0.50

12.00 = 3s + 3s + 1.5          _ add like terms

12.00 = 6s + 1.5                  _ - 1.5 on both sides

-1.5               -1.5

10.5 = 6s                  _ divide by 6 to isolate s

1.75 = s                         _ plug it in to find b

11.5 = 4(1.75) +2b

11.5 = 7 + 2b    _ subtract 7 on both sides

4.5 = 2b         _ divide by 2 on both sides

2.25 = b

Answer b = $ 2.25 dollars

             s = $ 1.75 dollars

Answers

Answer:

Did you know that Aronson and Carnes-McNaughton's have the perspective on how they   study

ancient  things from the past.I agree that Aronson will agree with Carnes--McNaughton's statement because they both  said the same thing but just in different words. For example  in the book "If Stones Could Speak," it will tell what  Aronson statement was about when it comes to archaeology  and in "Profiles Of Archaeologist," it will tell you the same statement but just in different words. For example it states in the book "If Stones Could Speak," on page 56 "Marc Aronson believes that, “It is about putting aside what you think you know, what has been passed along, and being willing to trust what you yourself see and to test it rigorously.” From this quote the reader will now know what Aronson thinks when it comes to archaeology. In "Profiles Of Archaeologist." On paragraph 19 It states "Being an archaeologist means looking at the world around us in a different perspective. We live in the present as we study the past in  order to learn what  to do in the future---- on this planet and possibly other. We learn to be humanities  while at the same time we practice as scientists.  From this quote the reader can understand that both of these statements are similar but they are just reworded. In closing, This why I think that Aronson and Carnes will agree to what to what there statement was.

Step-by-step explanation:

Answer:

Part 1: At eight hours they both charge the same.

Part 2: Flush Plumbing charges the least

Step-by-step explanation:

Part 1:

Flush Plumbing Co Equation: 50 + 10 h (h = hours)

Fire-in-the-hole Plumbing: 90 + 5h (h = hours)

50 + 10h = 90 + 5h

Solve the Equation:

5h = 40

h = 8

Part 2:

Plug in 7:

Flush Plumbing: 50 + 10 x 7 = 50 + 70 = $120

Fire-in-the-hole Plumbing: 90 +5 x 7 = 90 +35 = $125

Flush plumbing chargers the least
