Answer:
158
Step-by-step explanation:
10.89-2.99 = 7.90
.5/7.90=158
Answer:
Step-by-step explanation:
The salaries are the same. Only the fraction of how much is saved is quite different.
Equation
x ( 9/11 - 7/9) = 1584
Explanation: The salary amount is x. The fractional amounts saved are also given. You have to take the difference because one of the people saves more than the other.
The amount that is more is 1584.
Solution
9/11 = 0.8182
7/9 = 0.7778
9/11 - 7/9 = 0.8182 - 0.7778 = 0.0404
Put that into the equation.
x(0.0404) = 1584 Divide by 0.0404)
x(0.0404) = 1584/0.0404
answer:x = 39204
W= 7
38=2w+2(12)
/
38=2w + 24
-24 -24
14=2w
divid by 2 divid by 2
7=w
Answer:
<em>x = ± ( 5√5 - 3 ) / 2</em>
Step-by-step explanation:
We are given the equation ( 2x + 3 )² = 125;
<em>Solution ; x = ± ( 5√5 - 3 ) / 2</em>
Keeping in mind that "R" and "r" are constants whilst "s" is a variable and θ is a function in terms of "s", thus
![\bf s^2=R^2+r^2-2Rrcos(\theta )\implies 2s^1=0+0-2Rr\left[ \stackrel{chain~rule}{-sin(\theta )\cfrac{d\theta }{ds}} \right] \\\\\\ 2s=2Rrsin(\theta )\cfrac{d\theta }{ds}\implies 2s=\cfrac{2Rrsin(\theta )d\theta }{ds}\implies \cfrac{2s\cdot ds}{2Rr}=sin(\theta )d\theta \\\\\\ \cfrac{s\cdot ds}{Rr}=sin(\theta )d\theta](https://tex.z-dn.net/?f=%5Cbf%20s%5E2%3DR%5E2%2Br%5E2-2Rrcos%28%5Ctheta%20%29%5Cimplies%202s%5E1%3D0%2B0-2Rr%5Cleft%5B%20%5Cstackrel%7Bchain~rule%7D%7B-sin%28%5Ctheta%20%29%5Ccfrac%7Bd%5Ctheta%20%7D%7Bds%7D%7D%20%5Cright%5D%0A%5C%5C%5C%5C%5C%5C%0A2s%3D2Rrsin%28%5Ctheta%20%29%5Ccfrac%7Bd%5Ctheta%20%7D%7Bds%7D%5Cimplies%202s%3D%5Ccfrac%7B2Rrsin%28%5Ctheta%20%29d%5Ctheta%20%7D%7Bds%7D%5Cimplies%20%5Ccfrac%7B2s%5Ccdot%20ds%7D%7B2Rr%7D%3Dsin%28%5Ctheta%20%29d%5Ctheta%20%0A%5C%5C%5C%5C%5C%5C%0A%5Ccfrac%7Bs%5Ccdot%20ds%7D%7BRr%7D%3Dsin%28%5Ctheta%20%29d%5Ctheta)
