The answer to this question is 8.3
Answer:
7 units
Step-by-step explanation:
A=pi*r^2
153.86=3.14*r^2
153.86/3.14=r^2
49=r^2
r=7
She needs to buy 3 sets of roses and 2 sets of daises
Answer:
Step-by-step explanation:
Here's how you solve this problem:
1. Solve for the slope in between the two points using (y2-y1)/(x2-x1)
For this problem that would be: (5-11)/(4+2), so the slope would be -1
2. Put that slope in a slope-intercept form equation and solve for the y-intercept.
Slope-Intercept Form: y=mx+b
y=-x+b
To solve for the y-intercept, use one of the coordinate pairs and input x and y.
11=-(-2)+b
9=b
3. Put that y-intercept back in the equation: y=-x+9
