Answer:
23.3225806
Step-by-step explanation:
First lets get 3% into decimal form.
3% is 3/100 = 0.03
Now multiply 0.03 by 47000 to get how much extra money she was going to get.
47000 * 0.03 = 1410
Now we just add
47000 + 1410 = 48410 is what she was going to make in 2012
Another way to do this is
(47000)(1+0.03) = 48410
you would use (1+0.03) which tells you she increased in pay.
Answer:
BC = 10.24
Step-by-step explanation:
You can use the Pythagoras theorem for this question
+ 
= 
a = 8cm
b = ???
c = 13cm
We will solve for B (length BC)
+ =
+ = 
Rearrange for b
= -
= 105
b = 
b = 10.24
Answer:
the room square side is 4.8m
Area of the room is= 4.8=²23.04²m
perimeter of square tiles=4a =1.2
a=1.2/4
or a=o.3m
area of the square tiles =0.3²=0.09m²
numbers of the tiles are rcover floor of the room
23.0.4/0.09=256
each tiles cost Rs 27
the total cost=256*27=6912
the th coalst cover by the th floor is Rs .6912
If you mean by a(t)=2t+9 is the acceleration function then we integrate...
v(t)=2t^2/2+9t+c where c is vo and we are told that that is -7 so
v(t)=t^2+9t-7 integrating again we get:
s(t)=t^3/3+9t^2/2-7t+c where c is the initial position which is 8 so
s(t)=t^3/3+9t^2/2-7t+8 which neatened up as
s(t)=(2t^3+27t^2-42t+48)/6
