Answer:
1. <
2. 23/24
3. 487 3/4
4. 29,725
5. Add 2 Add 4
15 17 19
16 19 23
17 21 27
18 23 31
19 25 35
20 27 39
Step-by-step explanation:
1. 11,437 is less than 11,473. 3, the tens place, is less than 7
2. Find the LCD of 5/8 and 1/3. It is 24, 5/8 * 3/3 = 15/24, 1/3 * 8/8 = 8/24
15/24 + 8/24 = 23/24
3. Divide 3902 by 8, 3902/8 = 487.75, As a mixed number, that is 487 3/4
4. 725 * 41 = 29,725
5. Add 2 to 17, 19, 21, 23, and 25. Add 4 to 19, 23, 27, 31, 35, and 39
6. Put each point on the graph, the horizontal line is first, and the vertical line is second:
Horizontal: Vertical:
17 and 19
19 and 23
21 and 27
23 and 31
25 and 35
27 and 39
To convert our number to scientific notation, we are going to move the decimal point to the right until we have only one non-zero digit to the left of the decimal point, and then, we are going to multiply that number by a negative power of 10 equal to the number of times we moved the decimal point to the right:
<span>
Our number is 0.000000016, so we need to move the decimal point 8 times to the right to have </span>only one non-zero digit to the left of the decimal point (1.6). Since we moved the decimal point eight times to the right, we are going to multiply 1.6 by y a negative power of 10 equal to the number of times we moved the decimal point to the right i.e.

.
So 0.000000016 expressed in scientific notation is 1.6x

, or in calculator notation 1.6E-8
We can conclude that the correct answers are <span>
1.6E-8 and </span><span>
1.6 × 10-8</span>
Answer:
x=-4
Step-by-step explanation:
These two angles have to equal 180 because they are opposite of each other. Therefore, the equation will be 129+x+x+59=180. You add all common terms. 2x+188=180. You want to isolate x so you have to subtract both sides by 188. Therefore, the equation will be 2x=-8. Divide both sides by 2 to isolate x. x=-8/2. This is equal to x=-4.
