5.5 : 30.80 = 7 : x
x = 7 * 30.80 / 5.5 = $39.20
Answer: $39.20
Answer:
Step-by-step explanation:
Here we have an implicit function, and so we must use implicit differentiation to find dy/dx.
(d/dx)(3y² - 6 = x) results in 6y(dy/dx) - 0 = (dx/dx), or 6y(dy/dx) = 1.
Then the desired derivative is
1
(dy/dx) = ---------
6y
Answer:
Step-by-step explanation:
Pythagorean theorum: 5^2 +s^2 = 15^2 so 25 + s^2 =225
s^2 =200 so s = square root of 200 which is 10 times the square root of 2. So the first answer is right
The lowest term of 315/1575 is 1/5 because they are both divisible by each other and 5. All you need to do is divide the top and the bottom.
Your answer is: 1/5
Have an amazing day!
3x/2 + x/1 = 9/4
(3x+2x)/2=9/4
5x/2 = 9/4
10x = 9
x = 9/10
