Answer:
If all three digits need to be the same (I assume that's what aaa means) it's 333
Step-by-step explanation:
For a number XYZ to be divisible by 9, X+Y+Z must be divisible by 9. Here's why:
X*100 + Y * 10 + Z = X + Y + Z + 99*X + 9*Y = X + Y + Z + 9(11X + Y)
So we need to find the smallest a so that a+a+a = 3a is divisible by 9. The smallest would be 0, but 000 is not a real 3-digit number. The next one is 3.
Answer:
240 days
Step-by-step explanation:
Create an equation where x represents the total number of days
Use the information that 40 days is 1/6 of the total:
40 = 1/6x
Now, solve for x:
40 = 1/6x
Multiply both sides by 6, since it is the reciprocal of 1/6
40 = 1/6x
240 = x
So, the total number of days he has to record data is 240 days.
I would say 90 degrees. I say this because triangles always will equal 180 so 60 + 30 = 90 and 180 - 90 = 90 degrees!!
Maybe its right. Maybe its wrong!
to vertically compress a function, f(x) by a factor of d, we multiply the whole function by d, so f(x) becomes d*f(x)
to shift a function to the right by c units, subtract c from every x
so f(x) becomes f(x-c)
to shift a function up by c units, add c to the whole function
so f(x) becomes f(x)+c
ok, given f(x)=5x
vertically compress by 1/4, multiply whole thing by 1/4
shift right 3 units, minus 3 from every x
shift up 2 units so add 2 to whole function
if you expand it you get
