Answers
Answer:
143 degrees
Step-by-step explanation:
The shape is a hexagon therefore the total angle will be 720 degrees.
The sum of the total angle of the shape is 434 degrees
So to get the answer the equation is:
434 + x + x = 720 degrees
So x = 143 degrees.

Find the equation for the vertical line that goes through point M(−2, 6).
Answers
Answer:
Step-by-step explanation:
Every possible value of y will have an x value of x = - 2 associated with it. For example (-2, 58) is also on this vertical line. A line with more than 1 y value associated with x means the line you get is not a function.
The equation you want is x = - 2
8. A submarine's elevation is -14.5 feet relative to sea level. A shark is
swimming at an elevation -56.8 feet. What is the difference in elevation
between the submarine and the shark?
a) 71.3 feet b) 56.8 feet c) 42.3 feet d) 14.5 feet
Answers
Answer:
C.)42.3
Step-by-step explanation:
If it's difficult to do subtraction with negatives, switch them to positive and subtract 14.5 from 56.8. In order to get a lesser negative number(negatives closer to -1 are greater), you have to add a positive number. My math teacher taught me this simple but effective method. This method is used for multiplication and division but it helps:
(Hate=Negative and Love=Positive)
If you hate to hate, you love.(neg. x neg=pos.)
If you hate to love, you hate(neg. x pos.=neg.)
If you love to love, you love(pos. x pos.=pos.)
If you love to hate, you hate(pos. x neg.=neg.)
c) 42.3 feet
Step-by-step explanation:

(5+3)*3
(5+3)*9
Answers
Answer:
The difference is one number is larger than the other.
Step-by-step explanation:
we are doing BOMDAS
so (5+3)*3
we start with the bracket first since we are dealing with BOMDAS
(5+3)*3 = 8*3
then we multiply the 8*3 which equals to 24
(5+3)*9
we start with the bracket first (5+3) equals to 8 and then we multiply the 8 by the 9 and the answer is 72
(5+3)*9
(5+3)= 8*9
= 72
between 24 and 72 the difference is 72 is larger

"Find the measures of two supplementary angles if their measures are 3:7
Since the ratio is 3:7 we can assume that the angles are equal to 3x and 7x?"
3x+7x=180° (180° since a line is equal to that)
then solve
10x=180
x=18
then substitute x=18 in 3x and 7x
3x=54°. 4x=126°
126° and 54°
Answers
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
Answer:
The two angles are 54 degrees and 126 degrees.

Answer:
43.70 ft
Step-by-step explanation:
The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides. The correct computation is ...
Hypotenuse is √(7² +7²) = √(49 +49) = √98 = 7√2
Perimeter of pentagon is ...
7 +7√2 +7√2 +7√2 +7 =
7 +21√2 +7 =
14 +21√2 ≈ 14 +29.70 =
Perimeter is approximately 43.70 ft.
__
There are two errors:
side lengths were used instead of their squares to find the hypotenusecontents of radicals were added, rather than coefficients of themBoth errors are easy to find if you know what the computation is supposed to look like.
The Pythagorean theorem involves a sum of squares.

Alice got these scores in her exam English 45 out of 50. music 45%. art 25 out of 40. maths 85% which subject did Alice get her highest and lowest scores in .
Answers
Answer:
English: 45/50 = 0.9 = 90%
Music: 45%
Art: 25/40 = 0.625 = about 63% (if you round up)
Math: 85%
As you can see: English - highest | Music - lowest
Alice got her highest score in Maths, and her lowest score in Music.
To find out which subject Alice got her highest and lowest scores in, let's compare the scores in each subject.
English: 45 out of 50 = 45/50 = 0.9 (90%)
Music: 45 % = 45/100 = 0.45
Art: 25 out of 40 = 25/40 = 0.625 (62.5%)
Maths: 85 % = 85/100 = 0.85
Now, we can see that the highest score is in Maths (85%) and the lowest score is in Music (45%).
So, Alice got her highest score in Maths, and her lowest score in Music.

Michael bought 8 new Pokemon cards to add to his collection.
The next day his dog ate half of his collection. There are now only
40 cards left. How many cards did Michael start with?
Answers
Answer:
72
Step-by-step explanation:
I like to work backward with problems like these. I'll start out with 40. Then it says that his dog ate half of this number. Instead of dividing by 2, I'll have to multiply by two since I'm working backward.
So, now I have 80, the number of cards he had before his dog ate half of the collection. We also see that he bought 8 new Pokemon cards and added these two his collection. Instead of adding 8, I'll subtract 8 from 80, giving me 72. So, this is his original amount.
If I take this number and go back through the scenario, I can check my work.
72 + 8 = 80, 80/2 = 40
