Answer:
The First Table
Step-by-step explanation:
All values can be said to be directly proportional to one another being multipled by 3.
Time=number of cuts times time it takes to make each cut
to cut something into 2 pieces, you need 1 cut
to cut into 3 pieces you need 2 cuts
therefor, to cut something into n pieces, it takes n-1 cuts
so 8piece is 8-1=7 cuts
time=number of cust times time per cut
time=7 times 5 minutes
times=35 minutes
Answer:
I think it's A is the answer
(-1.2,-2.0) and (1.9,2.2) are the best approximations of the solutions to this system.
Option B
<u>Step-by-step explanation:</u>
Here, we have a graph of two functions from which we need to find the approximate value of common solutions. Let's find this:
First look at where we have intersection points, In first quadrant & in third quadrant.
<u>At first quadrant:</u>
Draw perpendicular lines from x-axis & y-axis from this point . After doing this we can clearly see that the perpendicular lines cut x-axis at x=1.9 and y-axis at y=2.2. So, one point is (1.9,2.2)
<u>At Third quadrant:</u>
Draw perpendicular lines from x-axis & y-axis from this point. After doing this we can clearly see that the perpendicular lines cut x-axis at x=-1.2 and y-axis at y= -2.0. So, other point is (-1.2,-2.0).
Answer:
48
Step-by-step explanation:
Wrong : right
1 :12
Multiply by 4 because she gets 4 problems wrong
1*4 : 4*12
4 :48
If she gets 4 problems wrong, she gets 48 problems right
