Answer: $200
Step-by-step explanation:
Given: In 1 year ,
Linda's parents spend $2400 on cable and internet service.
If they spend the same amount each month, Monthly payment = 
![=\dfrac{\$2400}{12}\ \ \ [\text{Number of months in a year}=12]\\\\=\$200](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5C%242400%7D%7B12%7D%5C%20%5C%20%5C%20%5B%5Ctext%7BNumber%20of%20months%20in%20a%20year%7D%3D12%5D%5C%5C%5C%5C%3D%5C%24200)
Hence, the resulting monthly change in the family's income = $200
F=1.8C+32
We are given C=-20 degrees
plugging this value in the given equation
F=1.8(-20)+32
F=-36+32=-4
F=-4 degree fahrenheit
Since Sylvanite only contains 28% gold by mass, then to obtain 81.0 grams of gold, x amounts of sylvanite must be mined. To determine x, we divide 81 grams by 28%. This equation is shown below:
0.28X = 81
X = 81/0.28
X = 289.29 grams
Therefore, 289.29 grams of sylvanite must be dug up to obtain 81 grams of gold.
