Answer:$1,929.20
Step-by-step explanation:First off, I noted that the answers are pretty far apart so I rounded up to $50 to make it simpler (you should only do this if the answers are pretty far apart from one another.)
$50 per day × 5 days per week × 8 weeks = $2,000. Closest answr (because I rounded) is $1,929.20.
Answer:
I believe the value would be 9.
First find the amount of the difference between the original price and the current price:
$10,600 - $7,400 = $3,200
Divide the difference by the original price:
3200 / 7400 = 0.4324 = 43.2% increase.
Answer:
Twenty two over nine.
Step-by-step explanation:
The bar over the 4 means that 4 is recurring .44444......... It goes on with out bounds and is equal to 4/9.
So 2.4 = 2 4/9
= 22/9.
Answer:
D) 1/5 e 1/3
Step-by-step explanation:
You have the following quadratic equation:
(1)
In order to find the values of x that are solution to the equation (1), you first find the solution for k in the following equation:
![2(k-8)+3(-k+1)=-4k+11\\\\2k-16-3k+3=-4k+11\\\\2k-3k+4k=11+16-3\\\\3k=24\\\\k=8](https://tex.z-dn.net/?f=2%28k-8%29%2B3%28-k%2B1%29%3D-4k%2B11%5C%5C%5C%5C2k-16-3k%2B3%3D-4k%2B11%5C%5C%5C%5C2k-3k%2B4k%3D11%2B16-3%5C%5C%5C%5C3k%3D24%5C%5C%5C%5Ck%3D8)
Next, you replace the previous value of k in the equation (1) and you use the quadratic formula to find the roots:
![15x^2-8x+1=0\\\\x_{1,2}=\frac{-(-8)\pm \sqrt{(-8)^2-4(15)(1)}}{2(15)}\\\\x_{1,2}=\frac{8\pm 2}{30}\\\\x_1=\frac{1}{5}\\\\x_2=\frac{1}{3}](https://tex.z-dn.net/?f=15x%5E2-8x%2B1%3D0%5C%5C%5C%5Cx_%7B1%2C2%7D%3D%5Cfrac%7B-%28-8%29%5Cpm%20%5Csqrt%7B%28-8%29%5E2-4%2815%29%281%29%7D%7D%7B2%2815%29%7D%5C%5C%5C%5Cx_%7B1%2C2%7D%3D%5Cfrac%7B8%5Cpm%202%7D%7B30%7D%5C%5C%5C%5Cx_1%3D%5Cfrac%7B1%7D%7B5%7D%5C%5C%5C%5Cx_2%3D%5Cfrac%7B1%7D%7B3%7D)
Then, the roots of the equation (1) are
D) 1/5 e 1/3
