Answer:
Volume of a in z = 876 ounces
Step-by-step explanation:
For z, the ratio of x and y is 3 : 11
x : y = 3 : 11 , which means in 14 parts of solution z : x will be 3 parts and y will be 11 parts
So, in 2520 ounces solution of z ,
Volume of a in z = { Volume of a in x + Volume of b in x }
Therefore,
So, Volume of a in z = 876 ounces
The expression is:
(z^2 - 4)
_______
z - 3
_______________
z + 2
___________
z^2 + z - 12
You can factor the numerator z^2 - 4 = (z + 2) (z - 2)
And the denominatior z^2 + z + 12 = (z + 4)(z - 3)
That permits to write the quotient as:
(z + 2)(z - 2)
___________
z - 3
_______________
z + 2
___________
(z + 4)(z - 3)
Now you can multiplicate the numerator of the numerator times the denominator of the denominator, and multtiplicate the denominator of the numerator times the numerator of the denominator to obtain:
(z + 2)(z - 2)(z + 4)(z - 3)
____________________
(z - 3)((z + 2)
Cancel the factors (z - 3) and (z + 2) because they are in both the numerator and the denominator =>
(z - 2)(z + 4) = z^2 + 2z - 8
The restrictions are that none of the cancelled factors can be 0, so z ≠ 3 and z ≠- 4.
It's gonna be a long problem: Remember PEMDAS
3n-5=8(6+5n)
3n-5= 48 + 40n Distribute 8 into parenthesis
3n-3n-5=48+40n-3n Put variable on one side.
-5-48=48-48+37n Isolate the variable
-43/37=37n/37 Isolate variable more
-1.162=n Simplify
The answer is repeating; that is a shortened version.
Answer:
the answer to the problem is -1/4
Put them in order from lowest to highest. Identify the lowest number in the data set, as well as the highest number. Subtract the lowest number in the set from the highest number. The resulting value is the range of the set of temperature values.
