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.
You can do this by first finding the y intercept which is the point where x = 0
-3(0) + y = 2
so y intercept is the point (0,2)
Now find the x intercept by putting y = 0
-3x = 2
x = -2/3
So we have 2 points (-2/3, 0) and (0,2) Draw a line through these 2 points and you have the required graph.
Answer:
use formula
Step-by-step explanation:
distance between the points A and B=
√((x2-x1)²+(y2-y1)²)
Answer:
1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of mg of sodium in 1 oz of chips.
y is the number of mg of sodium in a cup of soda.
Bryan ate 5 oz of chips and drank 1 cup of soda for a total of 650 mg of sodium.
This means that:
Jadyn ate 1 oz of chips and drank 5 cups of soda for a total of 250 mg of sodium.
This means that:
From the first equation:
Replacing in the second
1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.
Answer:
1) 13 ft
Step-by-step explanation:
1) 13+8=21 which is greater than 15. Would be a triangle.
2) 7+8=15 This would be a single line, not a triangle.
3) 3+8<15 This would be a single line, not a triangle.
2) 15+8=23 This would be a single line, not a triangle.
