TANQR
Answer: The length of the other diagonal is 10 cm...
So the diagonal formula is - 1/2* (d1*d2) d1 is the first diagonal and d2 is the second diagonal.
So,
1/2 * (8*d2) = 40
8d2= 40*2
d2= 80/8
d2= 10
Answer:
Arlo's weight = 52.3 kg
Explanation:
Let Arlo be "x"
Then,
Arlo = x
Bert = x+20 (Because Bert is 20 heavier than Arlo)
Cassie = x+20-5 (Because Cassie is 5 lighter than Bert)
Donnie =
(Because Donnie is half of Bert's weight)
Average = 57
Step by step Calculations:
57 =
(The whole divided by 4 because the total people is 4)
57*4 = x + x + 20 + x + 20 - 5 + 
228 = 3x + 35 + 
228 - 3x - 35 = 
193 -3x = 
2(193 - 3x) = x + 20
386 - 6x = x + 20
386 - 20 = x + 6x
366 = 7x
x = 
x = 52.3 kg (corrected to 3 significant figures)
Therefore Arlo's weight is 52.3 kg
25%=25/100
5=25/100*(number she wants to build)
(Number she wants to build)=5/25*100=5*4=20
