Answer:
1. 2 wholes is (2) tenths and (10) hundredths
2 wholes is (0) tenths and (4) hundredths
difference of 2.3 and .26 is (2.04)
2. Yasmine estimated the difference to be (82). The actual difference is (81.91)
Step-by-step explanation:
If you're asking how this is possible,
Answer and explanation:
If Sandy and Allen's mother does the job in 5 hours
And Allen and Sandy's contributions completes the job in 2.5 hours
5 hours - 2.5 hours =2.5 hours
Allen and Sandy's contribution is half of the time it took only Allen and Sandy's mother= 2.5 hours
Therefore Allen and Sandy together will take 2.5×2 = 5 hours to complete the job alone without their mother
A similar example: if it takes one person 2 hours to peel 5 potatoes and it takes 1 hour to peel same number of potatoes if a second person helps, then this second person reduces the time used by 1 hour(50%) and would take 2 hours to complete the work.
Answer:
There are two possible values for r (area): r =-7 or r=3
Step-by-step explanation:
Given the rectangular rug area is:
We have to convert the above equation into factored form.
So two numbers whose product is -21r² and sum is -4r
<=>
= 
= r (r -7) + 3(r -7)
= (r-7)(r+3)
We set = 0
<=> (r-7)(r+3) = 0
<=> (r-7) = 0 or (r+3) = 0
<=> r =-7 or r=3
So, there are two possible values for r (area): r =-7 or r=3

Answer:
The parent graph of (x-2)^4+1
shifts 2
units to the right and one unit up.
The parent graph of 3x^4-6 is stretched vertically by a factor of 3
and then shifted 6
units down.
The parent graph of 2(x+3)^4+10
is shifted 3
units to the left, stretched vertically by a factor of 2 and shifted 10 units up.
The parent graph of 1/4(6x-1)^4
is shifted one unit to the right, compressed horizontally by a factor of 1/6
, and compressed vertically by a factor of 1/4.
