The answer to the question is a
Percent means part out o 100
30.75%=30.75/100=3.075/10=0.3075/1=0.3075
thousandth is 3rd place
for 0.1234, thousandth would be the 3
to round to thousandth, look one place to the right (to the 4), if that number is:
greater than or equal to 5, add 1 to the thousandth place (3 turns to 4)
less than or equal to 5, leave the thousandth place as is (3)
so
0.3075
7 is thousandths
5 is before it and is equal to or greater to 5
7+1=8
0.308 is answer
0 means u do not move right or left at all and the 4 means u move up 4 units.
Answer:
* = b²
Step-by-step explanation:
You know that the square of a binomial is of the form ...
(x + y)² = x² + 2xy + y²
Matching given terms, we have ...
49 = y²
2xy = 14b
Solving the first of these relations for y, we have
y = √49 = 7
Putting that in the second relation and solving for x, we find ...
2x·7 = 14b
14x = 14b
x = b
Then the first term of the expansion, x², will be b².
The missing term is b².
We know the two angles add up to 180
5x + 134 + 2x + 32 = 180
Combine like terms
7x + 166 = 180
Subtract both sides by 166
7x = 14
Divide both sides by 7
x = 2
Have an awesome day! :)
