Answer: (total amount paid - $40) / 0.05
Step-by-step explanation:
Given the following :
Monthly fee = $40
Additional fee = $0.05 per minute on phone
Given the the amount paid for the month is available, number of minutes he was on phone can be determined thus :
Total amount to be paid = monthly fee + additional fee
Additional fee = $0.05 × n
Where n = number of minutes on phone
Hence,
Total amount paid = $40 + $0.05n
If the amount paid is known, the number of minutes on phone can be calculated thus;
(Total amount paid - monthly fee) = $0.05n
n = (Total amount paid - monthly fee) / fee per minute on phone
(total amount paid - $40) / 0.05
Answer:

Step-by-step explanation:
The complete question is
What is the length of leg y of the right triangle?
A right triangle with hypotenuse 26 and legs 24 and y
We need to use the Pythagorean Theorem, where
and
,
![h^{2} =x^{2} +y^{2}\\ 26^{2}=24^{2}+y^{2}\\y=\sqrt{26^{2}-24^{2}}\\ y=\sqrt{676-576}\\ y=\sqrt{100}\\ y=10](https://tex.z-dn.net/?f=h%5E%7B2%7D%20%3Dx%5E%7B2%7D%20%2By%5E%7B2%7D%5C%5C%2026%5E%7B2%7D%3D24%5E%7B2%7D%2By%5E%7B2%7D%5C%5Cy%3D%5Csqrt%7B26%5E%7B2%7D-24%5E%7B2%7D%7D%5C%5C%20y%3D%5Csqrt%7B676-576%7D%5C%5C%20y%3D%5Csqrt%7B100%7D%5C%5C%20y%3D10)
Therefore, the right answer is A. The length of the missing leg is 10 units.
Answer:
B: x=-2
Step-by-step explanation:
This is because x=-2 is where the parabola is split into two equal halves.
Answer:
I will show all the steps to lead to the solution.
1) 10b = 5 (√c + 2) <---- starting equation
2) divide by 5 => 2 b = √c + 2
3) subtract 2 => 2b - 2 = √c
4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.
Now these are two equivalent forms:
1) extract 2 from the parentheses: c = 4 (b -1)^2
2) expand the parentheses: c = 4b^2 - 8b + 4)
Step-by-step explanation:
Choice D
It is a math mathematical form of objects natural stance, to find it you need the positive integer and its finite sequence of digits.
