Answer:
0.2% increase
Step-by-step explanation:
First, you find the change between $15.50 and $18.60, which is 3.10. Then you do 3.10 divided by the original, which is 15.50. You should get 0.2.
2/5 of 20 = 8.
3/10 of 20= 6.
8+6=14. So 20-14= 6
She needs 14 pints, so you subtract 6 from that. Your final answer should be 8 pints.
To find the slope of the perpendicular line, you can take the negative reciprocal of the slope of the line it is perpendicular to.
Taking the negative reciprocal of -1/5 gives 5.
Now we have y=5x+b, where b is the y-intercept. Since we know that the perpendicular line passes through the point (1,4), we can substitute those values into the equation we have to find b.
y=5x+b
4=5(1)+b
4=5+b
b=-1
Therefore, the equation of the perpendicular line is y=5x-1.
Answer: 4
Step-by-step explanation:
We know that a plane is 2 dimensional surface that extends infinitely far.
The number of points required to define a plane = 3
Here , we have 4 points A, B, C, and D.
So, the number of possible combinations of 3 points to make a plane from 4 points = 
[ 
]
Hence, the greatest number of planes determined using any three of the points A, B, C, and D if no three points are collinear = 4.
