Answer:
7
Step-by-step explanation:
I can only answer these 2 questions aight?
1.) Jake bought 4 gadgets.
2.) You bought 3 drinks in Kroger.
Let us calculate the teacher's initial speed. It can be calculated as thus:
She does 5 papers in 30 minutes. Thus means her speed is 6 minutes per paper (Because
minutes per paper).
Now, if the teacher has to complete the remaining 30 papers in the remaining 150 minutes (2 hours 30 minutes=120+30=150 minutes), she will have to go through one paper in
minutes. Thus, her speed now will have to be 5 minutes per paper.
Now, we know that 1.2 times 5=6. Therefore, it will not be wrong to say that '' she has to be 1.2 times faster instead of 20% faster" because both mean the same.
Consider Point P to be (0,0) count the grid lines to find the location of points A, B and C
A=. (-6,-3)
B = (-9,6)
C =(3,9)
Now the scale is 1/3. So divide all the points by 3 to get the new location and place the green dots on them:
A’=(-2,-1)
B’ =(-3,2)
C’ =(1,3)
