Answers

Answer 1
the answer should be 6! all you have to do is plug the numbers into the equation!
it would be like this:
-1^2+3^2+(-1)-3
doing all of that would equal 6!

the interior sum of a triangle is 180 so add and subtract

63 + 49 = 112

180 - 112 = 68

Answer:

w = 68

Step-by-step explanation:

All angles add up to 180 so:

w + 63 + 49 = 180

w + 112 = 180

w = 180 - 112

w = 68

Answers

Answer:

C

Step-by-step explanation:

30*40=1,200

50%=0.5

1200*0.5 = 600

The answer is C
The reason to this is because the area of 30 and 40 is 120 and you divide that in half because 50% is half do you would get 600 therefore the answer is 600

What was the price, in dollars, of a gallon of milk at the end of 2013?

Answers

Answer:

Price at the end of 2011 :

$3.47 - 0.57 = $2.90

Price at the end of 2012 :

$2.90 + $0.25 = $3.15

Price at the end of 2013 :

$3.15 - $0.08 = $3.07

Step-by-step explanation:

please help im lost i dont understand this objective

Answers

Answer:

Explained Below

Step-by-step explanation:

You'll want to start off by knowing the formulas for the area and perimeter of triangles:

Area Formula - A= 1/2 bh (1/2 x base x height)

Perimeter Formula - P = a + b + c (sides added together)

So, we will plug in the numbers.

Triangle 1: A = 1/2 bh So, A = 1/2 8 x 10, which means half of 8 or 10 multiplied by the number that you did not half. (For instance: If you half 8, that means you multiply 4 and 10.) Now, you should have A = 40 either way (4 x 10 = 40 and 8 x 5 = 40).

P = a + b + c. So, you will add 8, 6, and 10. This is 14.

Triangle 2: A = 1/2 bh. But, this triangle requires you to cut in half. Doing this, that cuts your base as well. It will no longer be 30, by 15. For the left side of triangle 2, it will be A = 1/2 15 x 12, which you half either 15 or 12, where 12 is easier. Now it should be A = 15 x 6, which is 90. The right side of the triangle will be A = 1/2 15 (12) as well, which is also 90. In the end, you will add it together, which is 180.

P = a + b + c. So, you will add 15, 23, and 12 first. Then, add 15, 20, and 12. You should have 50 and 47, which you will add that together as well.

Triangle 3: I will keep working on this one, as I am a little unsure :/

Triangle 4: You will do the same steps for this triangle like you did on #2. Though the numbers you plug on are different. A = 1/2 bh - A = 1/2 10 x 14. (This is for the left side) You will have to half either the base or the height's number. So, it will be A= 5 x 14 or A=10 x 7. Then, you will multiply and find your answer (70). (This is for the right side) A = 1/2 10 x 14. Due to the numbers being the same, it can be shown that the area will also be 70. You then add 70 and 70 together.

P = a + b + c. You will add 10, 14, and 15 for the left side and 10, 14, and 17 for the right side. Once you add them separately, add the answers together (10+14+15 =39 and 10+14+17 = 41. 39 + 41 = 80.

Triangle 5: A=1/2 bh. A = 1/2 12 x 16. You will half either 12 or 16 (It does not matter). Then you should have A = 6 x 16 or A = 12 x 8. Either way, your answer is 96.

P = a + b + c. You will add 12, 16, and 18. This results in 46.

Hope this helps! I will continue to figure out Triangle 3

Answers

Answer:

A = 37 degrees ; B = 82 degrees

Step-by-step explanation:

the angle A plus 143 must measure 180 degrees

angle A = 180 - 143 = 37 degrees

the sum of the inner angles of a triangle is 180 degrees

A + B + C = 180

37 + B + 61 = 180

B = 180 - 98 = 82 degrees

82 Degrees is the answer

Using the two-way table, what percentage of the students that like to travel out of state do not like camping? Round to the nearest whole percent.

Column totals 88 112 200

36%
41%

Answers

to find a percentage of something you take the fraction and multiply it by a hundred

Step-by-step explanation:

step one

to determine what the fraction would be you just read the question:

first you have to see what they want to calculate the percentage of. In this case it's students who like traveling out of state but don't like camping.

88 students like traveling out of state and 36 of those students don't like camping so the fraction you have to use is 36/88

step two

next you multiply your fraction by 100 to calculate your percentage

36/88 ×100= 40.9%

step three

since you have to round to the nearest whole percent your answer would be 41%
