I think it is 1, 4, 6, and 7, although it looks different from when i learned this unit.
Eli will finish first.
Use 8/10 and 10/12. This represents how many spring rolls over how many minutes. Make your equations like this: 8/10 = 40/x and 10/12 = 40/x. Find x, which will give you the minutes it takes them to make 40 rolls.
You get x = 50 for the first one and x = 48 for the second. Nora makes 40 rolls in 50 minutes, and Eli makes 40 rolls in 48 minutes. Eli is faster.
Hope this helped! Please mark me brainliest!
Answer:
C) -7/3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-(-5))/(-2-4)=(9+5)/-6=14/-6
simplify -14/6 to -7/3
Answer : option D
we need to find out the graph shows a mixed-degree system with exactly one solution
The solution of two graphs will be the intersection of two graphs
In the first graph,
There is no intersection of both circles, So no solution
second graph,
The circle intersects the parabola at two point, so two solution for this graph
Third graph,
The circle and line does not intersects, so no solution
Fourth graph,
Both parabola intersects at one point, so one solution for this graph
So option D has exactly one solution
Answer:
Area= 1371.72m^2
Perimeter: 251.84m
Step-by-step explanation:
A1=L*W
A1=38*28
A1=1064
A2=3.14*r^2
A2=3.14*196
A2=615.44/2
A2=307.72
A1+A2=1371.72
