<span>If you would like
to know the values of these two numbers, you can calculate this using the following
steps:<span>
a + b = 77.95
a - b = </span></span>30.61 ... a = 30.61 + b
________<span>_______________
a + b = 77.95
(30.61 + b)
+ b = 77.95
30.61 + 2 *
b = 77.95
2 * b =
77.95 - 30.61
2 * b
= 47.34 /2
b = </span>47.34<span> / 2
b = 23.67
a = </span>30.61 + b = 30.61 + 23.67<span> = 54.28
Result:
The numbers are </span>23.67<span> and 54.28.</span>
Answer: 9(3+2)
Step-by-step explanation:
The GCF of 27 and 18 is 9 because the factors of 27 are, 1,3,9 and 27 and the the factors of 18 are, 1,2,3,9 and 18.
The greatest factor that they both share is 9.
And 9 times three is 27 and 9 times 2 is 18.
So you have to find how many seconds it takes to fill up with 1 inch.
TO find that, you have to divide 45/3 which equals to 15.
So it takes 15 seconds for 1 inch. The question is asking you to find out how many seconds will it take to fill the tub with 20 inches.
SO your gonna multiply 15*20.
15*20 = 300
So it would take 300 seconds to fill up Camden's tub.
Answer: A) 0.016
Step-by-step explanation:
The standard error is also known as the standard deviation of sampling distribution.
Formula : 
Given : The proportion of respondents approve the job that President Barack Obama was doing handling the economy : 
Sample size : n= 1000
Then, the standard error (SE) of 
is
Hence, the standard error (SE) of is 0.016 .
