It's 29/7 or 4 and 1/7 as the mixed number
Answers:
x = 9
y = -3
==============================================================
How to get those answers:
Simply multiply the coordinates of the point (3,-1) by the scale factor 3.
The new x coordinate will be 3*3 = 9 and the new y coordinate will be -1*3 = -3.
The point (3, -1) moves to (9, -3) after applying the dilation.
The rule I used is
where k is the scale factor, which is k = 3 in this case.
Note how k > 1 means the point moves further away from the origin. It also means we have an enlargement.
In minutes it is 1500 min because if you just multiply 25 and 60 it equals 1500. I got the 60 from 60 sec. in one minute.
Answer:
34.9
Step-by-step explanation:
Because if you multiply then divide by 2 that will help you alot.
Initial number = 36
Final number = 63
Change in number = 63 - 36
= 27
Percentage change = (27/36) * 100
= (3/4) * 100
= 3 * 25
= 75 percent
So the percentage change from 36 to 63 is 75%. I hope the procedure for solving is absolutely clear for you to understand. In future you can attempt such problems by following the procedure shown and you will require no further help from outside. Just be careful about the numerator and the denominator.
